Description

Filterless water purification system

The present invention relates to a water purification device, and more specifically, water and oil contaminated using circulation and centrifugation, without the use of filters, water and sewage management industry, industrial machinery operation industry, rainwater treatment industry, food processing industry, It relates to a filterless water purifier that can be applied to aquaculture industries, industrial facilities using cooling water, golf courses, and island areas where water purification is required.

In general, raw water that has not been filtered through a water purification equipment (purifying water filtration device) contains various impurities. Only 52% of tap water users directly consume raw water that has not purified impurities for domestic and industrial use, for example, domestic use. The water supply to each household through the water meter is mixed with rust and foreign substances in the tap water by the old pipes of each building, so it is difficult to drink the tap water directly. Therefore, only drinking water is actually used for drinking water and purified water. There has been a demand for a method to solve the various parts as described above. In addition, when manufacturing plastic products, when used as cooling water, impurities are deposited in the heat exchanger, which can cause a significant impediment to the performance of the heat exchanger. When used as irrigation water for production and raw vegetables, crop damage will occur.

Such industrial water purification equipment (purifying water filtration equipment) is a facility that supplies industrial or industrial water. When processing or manufacturing various products, organic and inorganic pollutants contained in raw water for cooling or washing, various bacteria or It is a facility for supplying purified water by removing ionic substances including viruses and heavy metals. It is currently used in a wide range of fields and is gradually expanding its scope of use.

A number of technologies have emerged, such as industrial water purifying equipment (purifying water filtration equipment), such as Patent Registration No. 876548, "Industrial Water Purification Equipment", and Public Utility Model No. 1998-69008, "Industrial Water Purifying Equipment." Mainly used in industrial sites, groundwater or polluted water mixed with foreign substances and impurities has many differences in water quality in each region, so in places where water quality is poor, the filter installed inside the water purifier housing and the water purification equipment equipped with this filter There is a problem that the structure is complicated and it is not possible to remove foreign substances from ground water or polluted water with a structure other than the filter installed in the industrial water purification equipment (water filtration equipment).

There are several types of water treatment processes, but recently, the use of membrane filtration devices using membranes has been increasing in the treatment of purified water, sewage, wastewater, reuse, seawater desalination, ultrapure water, etc. It can be divided into microfiltration membrane (MF), ultrafiltration membrane (UF), nanofiltration membrane (NF), and reverse osmosis membrane (RO) according to pore size.

In a water treatment device including a membrane filtration device, the recovery rate means the amount of the final treated water compared to the raw water to be treated. If the amount of treated water is small even though a lot of treated water is input, many more processes are required to secure the same treated water, so it is uneconomical, and many studies are being conducted to increase the recovery rate.

On the other hand, in the membrane filtration process, in order to control membrane fouling, the filtration mode and the cleaning mode, especially backwashing, are continuously operated at regular intervals.

However, in general, when only one membrane filtration unit is used, the recovery rate is only about 85% to 95%. Therefore, in order to achieve a high recovery rate, it is common to use two or more membrane filtration units together. In particular, for efficiency, it is recommended to use a membrane filtration unit of 1 stage with a high recovery rate of about 85 to 95%, and a membrane filtration unit of 2 stages having a recovery rate of about 80 to 90% and treating backwash concentrated water. It is common. In this case, the total recovery rate is known to be 98% to 99%.

For the membrane filtration process according to the prior art and its cleaning mode, the pre-treatment water treated in the pre-treatment section is stored in the pre-treatment water storage section of the main treatment section, and the filtered water filtered in the first membrane filtration section is the membrane filtration processing water storage section. And filtered to the post-treatment unit, unfiltered unfiltered concentrated water from the first membrane filtration unit is transferred to the first backwash concentrated water storage unit, and treated water retreated from the second membrane filtration unit is membrane filtered. Combined into the treated water storage and stored, the second concentrated water that has been untreated and excluded is transferred to the concentrated water treatment.

Chemicals such as flocculants, oxidizing agents, and antimicrobial agents are injected into the front end of the first membrane filtration unit and the second membrane filtration unit through the chemical injection unit, and an oxidizing agent such as sodium hypochlorite (NaOCl) is backwashed to control membrane contamination. In the mode, the first membrane filtration backwash pump portion and the second membrane filtration backwash pump portion are injected into the front end.

For the cleaning process to control membrane contamination after the filtration process, the first membrane filtration unit is physically cleaned by the first membrane filtration backwash pump unit and the first membrane filtration scrubbing washing unit, and the second membrane filtration unit is the second membrane filtration station. Physical cleaning is performed by the washing pump unit and the second membrane filtration scrubbing washing unit.

In addition, since membrane fouling occurs due to long-term operation in the membrane filtration process, and the performance of the filtration membrane is deteriorated, backwashing of water or air, air scrubbing, and flushing after a filtration process for a predetermined period of time. A cleaning process such as "physical cleaning" such as (flushing) is performed, and when recovery is not possible by physical cleaning, "CIP (chemical in place)" is performed using chemicals.

First, the pre-treatment water in the pre-treatment water storage tank is filtered through a first membrane filtration module in a first membrane filtration module and stored in the membrane filtration treatment water storage tank. In addition, as the filtration mode of the two-stage membrane filtration process, untreated concentrated water from the first-stage membrane filtration process stored in the first backwash concentrated water storage tank is transferred from the second membrane filtration module in the second membrane filtration immersion tank with a second membrane inflow pump. It is filtered and stored in a membrane filtration water storage tank, and the more concentrated sludge that is not filtered is transferred to the concentrated water treatment unit.

Next, in the cleaning mode, the membrane filtration concentrated water generated immediately after the filtration mode concentrated in the first membrane filtration module 202A of the first membrane filtration unit is drained to the first backwash concentrated water storage tank, In the cleaning mode, immediately after air scrubbing of the first membrane filtration scrubbing scrubber through the first membrane filtration scrubbing feeder, the air-washed concentrated water is discharged and transferred as a downstream flow to the first backwash concentrated water storage tank, and the membrane filtration treated water The treated water produced in the filtration mode of the storage tank is backwashed using a first membrane filtration backwash pump, and immediately afterwards, the backwash concentrated water is discharged and transferred as a downstream flow to the first backwash concentrated water storage tank.

In addition, in the washing mode of the second membrane filtration unit, sludge under the second membrane filtration immersion tank, which is generated immediately after air cleaning of the second membrane filtration scrubbing washing unit through the second membrane filtration scrubbing feeder, flows downward to the concentrated water treatment unit. The discharged and transported, and the treated water produced in the filtration mode of the membrane filtration water storage tank is backwashed using the second membrane filtration backwash pump, and the sludge under the second membrane filtration immersion tank immediately generated is sent to the concentrated water treatment section. It is discharged and transferred in a downstream flow.

As described above, as described above, the application of the floating separation method as a physical cleaning method of the prior art membrane filtration process is because the flow direction of the discarded air washing concentrated water and backwashing concentrated water is downstream and the floating separation method is upstream. There was a difficult problem.

In addition, as described above, the physical cleaning method of the prior art membrane filtration process requires a periodic cleaning or replacement of the filtration membrane or filter, resulting in a high maintenance cost.

In addition, as described above, the physical cleaning method of the prior art membrane filtration process has a problem in that most of the cleaning targets are limited to water and cannot be applied to industrial sites that want to purify oil or cooling water.

A first water purification chamber (23a), which is divided into the collection chamber (21) and is divided into a partition plate (22) so that the fluid that has passed through the filter unit (50) is simultaneously filled and flows sequentially in an overflow manner. The cross-section forming the n-purification chamber 23n forms a water purification chamber 23 having a'Y' shape.

Here, a fresh water outlet end 23n' through which clean purified water is discharged is formed on an upper side of the n-th water purification chamber 23n.

At this time, the water purification chamber 23 is arranged, the first water purification chamber (23a) to the n-th water purification chamber (23n) is installed in a sequential series arrangement based on the collection chamber 21, the area of each chamber and the partition plate The height of (22) is produced by calculating and calculating the water-purifying capacity and the over-proiling capacity.

The height of the dividing plate 22 is between the first water purification chamber 23a and the second water purification chamber 23b, the first partition plate 22b, the second water purification chamber 23b and the third water purification chamber 23c. ), the second partition plate (22c), the third water purification chamber (23c) and the third partition plate (22d) located between the n-th water purification chamber (23n) is installed, the height is formed the same .

It is configured to supply the sediment and sludge collected and deposited on the lower part of the water purification chamber 23 to the cyclone treatment unit 40 to re-supply the purified fluid from which condensed foreign substances and solids are separated into the water purification chamber 23.

This, the water purification chamber 23 is divided into a partition plate 22 is installed, debris and solids, slurry is precipitated flows toward the center to form a first inclined bottom plate 24 inclined downward and inverted pentagonal The water purification part 27 is formed.

That is, the bottom of the water purification chamber 23 forms a second inclined bottom plate 25 so as to decrease as it progresses in the direction of the nth water purification chamber 23n based on the first water purification chamber 23a.

In more detail, when the water to be purified is filled in the water purification chamber 23, foreign matter, solids, and sediment sink to the first inclined bottom plate 24, move by inclination, and then move to the sediment collection section 28. The inclination of the collecting section 28 is moved and moved.

Here, the water purification chamber 23 is installed to sterilize bacteria, pathogens, bacteria, etc. existing on the surface of the water by installing an ultraviolet sterilization lamp 26. In the present invention, a separate frame is disposed on the top of the third water purification chamber 23. The installation is explained using an example, and the location may be changed as needed.

On the other hand, the cyclone processing unit 40 is formed at one side of the supply end 41 is supplied from the pump 30 and the discharge end 42 is formed to discharge the condensed and agglomerated foreign matter and solids by centrifugation is discharged (42) A body 43 in the form of a tapered tube having a small diameter is formed.

On the upper part of the body 43, a water purifying passage 44 is formed at the center so as to discharge the purified water from which foreign substances and solids are separated and discharge it to the water purification chamber 23.

In another embodiment, a water purifying pipe 46 for guiding the discharge of the fluid rising from the body 43 may be configured in the water purifying passage 44 of the cover 45.

In addition, the body 43 is configured in a cylindrical shape in which a cylindrical section and a conical section are combined.

The cyclone processing unit 40 is a device that uses the principle of centrifugal force dust collector (CYCLONE) to directly separate and remove particles using the difference between the centrifugal force and inertia force of gas and dust without using other devices such as filter media, water, and electricity. In the case of large and large specific dust, it can be used alone.

As a type of application of the cyclone treatment unit 40, the tangential inflow method is a method in which the fluid to be treated flows into the side of the cylinder, and the inlet flow rate is 7 to 15 m/s, and the pressure loss can be configured to be about 100 mmAq. have.

In addition, the axial flow method is a method in which the fluid to be flowed is introduced and processed in a moving axial direction to create a swirl flow by installing a spiral induction fan. The inlet flow rate is 10 m/s, and the pressure loss is applied to a multi-cyclone of about 80 mmAq. It can also be configured.

In addition, it is possible to configure the generator 60 for supplying the power required for the operation of the circulating water purifier 100, the generator 60 is a sudden power failure or power supply smoothly in a place where the water purification process is required in real time It is installed in case it cannot, and is separately installed to supply electric power to the motor, pump 30 and UV sterilization lamp 26 for operating the filter unit 50.

In addition, the circulation type water purification device 100 may be configured by installing a separate control unit 70 to control the operation of the generator 60, the filter unit 50, the pump 30, and the UV sterilization lamp 26. .

In addition, the purified water fluid that can be purified using the circulating water purification apparatus 100 includes water, sewage, rainwater, aquaculture water, oils, cutting oil, cooling water, and brine.

Looking at the use state of the circulating water purification device 100 configured as described above is as follows.

As shown in Figures 1 to 9, while operating the control unit 70 to rotate the belt filter 51 of the filter unit 50 through manipulation, and at the same time filter water to be filtered through the raw water pipe 10 Drain it with the belt filter 51 of (50).

At this time, in the fluid to be purified, the fluid passes through the belt filter 51 and foreign matter is caught, and the foreign matter collected in the collection chamber 21 by the rotating belt filter 51 is periodically discharged.

Subsequently, the purified water from which the foreign matter is removed from the filter unit 50 flows into the inside of the first purification chamber 23 of the purification chamber 23 and fills up from the sediment collection unit 28 of the purification chamber 23. It is evenly distributed into the water purification chambers 23a to n-th water purification chambers 23n to fill up.

Next, when the purified water is continuously supplied through the raw water pipe 10 in a state where the purified water fluid is full in the purified water chamber 23, the first divided water plate is supplied to the first purified water chamber 23a. (22b) overflows and flows into the second water purification chamber 23b, and when the water to be purified is full in the second water purification chamber 23b, the second partitioning plate 22c overflows and the third water purification chamber 23c When the water to be purified is filled in the third water purification chamber 23c, the third partition plate 22d overflows and flows to the nth water purification chamber 23n.

At this time, when the first water purification chamber (23a) to n-th water purification chamber (23n) flows through the process of overflow, it is not filtered by the belt filter (51). 1 It is deposited on the inclined bottom plate (24).

Thus, the first water purification chamber 23a to nth water purification chamber 23n is filled or overflowed with foreign matter, solids, and sludge of the water to be purified fluid are settled on the first inclined bottom plate 24 and then flowed along the slope. When it moves to the sediment collection part 28, it flows back to one side along the inclination of the second inclined bottom plate 25.

In addition, the ultraviolet sterilizing lamp 26 is irradiated with ultraviolet light to sterilize bacteria, pathogens, and bacteria in the fluid to be flowed.

Then, the foreign matter, solids, and sludge flowed by the second inclined bottom plate 25 flow along a slope and are supplied to the cyclone processing unit 40 by the pumping force of the pump 30 through the foreign material discharge port 25a.

That is, when the pump 30 is operated, the purified water fluid containing foreign matter, solids, and sludge collected in the second inclined bottom plate 25 is provided through the supply end 41 of the cyclone treatment unit 40 to the body 43. Spray to rotate along the inner wall surface.

In more detail, when the water to be purified flows into the interior of the body 43 through the supply end 41, a strong rotational force starts inside the body 43 due to the inflow in the tangential direction of the inner wall surface, thereby causing strong vortex movement. It occurs inside, and a centrifugal force accelerating the movement of foreign substances toward the outside occurs, so that the particles move downward in a spiral through the cylindrical portion and the cone portion.

In addition, the particles in the powerful vortex motion inside the body 43 are affected by gravity, centrifugal force, and drag force, and the influence of gravity is smaller than the other two forces. . The fluid containing the fine fraction moves to the center of the body 43 under the influence of drag, and forms a strong upward flow generated here, discharged through the water purification passage 44 at the upper center, and is discharged through the second water purification chamber. (23).

At this time, the fluid purified through the cyclone processing unit 40 and introduced into the second water purification chamber 23b flows sequentially along the second water purification chamber 23b to the nth water purification chamber 23n to undergo an additional water purification process. do.

On the other hand, the large particle (coarse fraction) is controlled by the centrifugal force acting in the circumferential direction, and the particle is prevented from flowing inward, whereby particles moving to the inner wall surface of the body 43 collide with the inner wall and inertia force. And is discharged to the belt filter 51 of the filter part 50 after being discharged along the wall of the cone part and separated through the lower discharge end 42 as a sludge or porridge state, and then discharged to the collection chamber 21.

In addition, when the water purification pipe 46 is formed in the cyclone processing unit 40, fresh water is drained to the second water purification chamber 23b through the water purification passage 44 through the water purification pipe 46.

At this time, the fresh water, which is moved to the n-th water purification chamber 23n and is full of purified water, is drained through the fresh water outlet end 23n'.

That is, the circulating water purification device 100 is continuously and semi-permanently purified by using a water purification method for separating foreign substances while flowing through the water purification chamber 23 and a water purification method for separating foreign substances by using the cyclone treatment unit 40. There are possible features.

In the above description, specific shapes and directions have been mainly described in the description of the circulating water purification device of the present invention with reference to the accompanying drawings, but the present invention can be variously modified and changed by those skilled in the art, and such modifications and changes are the scope of the present invention.
