Example 1
According to an embodiment of the present invention, there is provided an embodiment of a urea-based water purification method, it is noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than that presented herein.
Fig. 1 is a flow chart of a water purification method based on a urea machine according to an embodiment of the invention, as shown in fig. 1, the method comprises the following steps:
and S102, controlling the water purifier to filter the water source to be filtered to obtain a first water source.
In step S102, the water purifier is disposed in a urea machine, and the water source to be filtered may be tap water, where the urea machine is a vehicle urea machine. Optionally, the water source to be filtered is subjected to filtration treatment, which may include two treatment steps of pretreatment and reverse osmosis treatment, wherein the pretreatment mainly includes filtering out impurities with large particles, such as silt and clay, in the water source to be filtered, and the reverse osmosis treatment mainly filters impurities such as dissolved salts, colloids, bacteria and viruses in the tap water.
It should be noted that tap water cannot be directly used for producing the urea solution, and the tap water needs to be purified by a water purifier before being used for producing the urea solution.
And step S104, storing the first water source to a preset water tank under the condition that the conductivity of the first water source is smaller than the preset conductivity.
In step S104, when the conductivity of the first water source is less than the preset conductivity, it indicates that the first water source has satisfied the requirement of pure water, and the user can drink the first water source. Optionally, the preset conductivity is 20 μ s · cm.
In addition, in step S104, the pre-set water tank may be, but is not limited to, an ultrapure water tank in which stored water is used to produce a urea solution.
Step S106, controlling the water purifier to execute corresponding water purification operation according to the water amount in the preset water tank, wherein the water purification operation at least comprises the following steps: a first water purification operation for purifying a first water source into drinking water, and a second water purification operation for purifying the first water source into a second water source for producing a urea solution.
Optionally, when the amount of water in the ultrapure water tank (i.e. the preset water tank) has reached the maximum capacity of the ultrapure water tank, it indicates that the urea machine is not producing urea solution any more, and at this time, the water purifier directly stores the first water source into the pure water tank for the user to drink. When the water amount in the ultra-pure water tank (namely the preset water tank) does not reach the maximum capacity of the ultra-pure water tank, the urea machine is indicating to produce the urea solution, at the moment, the water purifier further performs water purification treatment on the first water source to obtain a second water source, and the second water source is utilized to produce the urea solution.
It should be noted that, as shown in step S106, the water source purified by the water purifier in the urea machine of the present application can be used not only for producing the urea solution, but also as drinking water for users, so that the functions of the urea machine are diversified.
Based on the solutions defined in the foregoing steps S102 to S106, it can be known that, in the embodiment of the present invention, different filtering manners are adopted for different requirements to filter the water source to be filtered, a first water source is obtained by controlling the water purifier to filter the water source to be filtered, and the first water source is stored in the preset water tank when the electrical conductivity of the first water source is smaller than the preset electrical conductivity, and then the water purifier is controlled to execute a corresponding water purification operation according to the water amount in the preset water tank, where the water purification operation at least includes: a first water purification operation for purifying a first water source into drinking water and a second water purification operation for purifying the first water source into a second water source for producing a urea solution.
It is easy to notice that, in the above-mentioned process, the water purification operation that the purifier was executed is determined to the water yield in the predetermined water tank to make the water that the purifier generated can be used for producing urea solution, also can be used for generating drinking water, and then make the urea machine not only can produce urea solution, still can generate drinking water and supply the user to drink.
Therefore, the purpose that the urea machine can produce the drinking water while producing the urea solution is achieved through the scheme provided by the application, the technical effect of perfecting the function of the urea machine is achieved, and the technical problem that the existing urea machine can only generate the urea solution and cannot provide the drinking water is solved.
In an alternative embodiment, fig. 2 shows an alternative water purification method based on a urea machine, as shown in fig. 2, the urea machine firstly controls the water purifier to filter the water source to be filtered, and a first water source is obtained. Specifically, firstly, the water source to be filtered is subjected to second filtering treatment to obtain a pretreated water source, and then the pretreated water source is subjected to reverse osmosis treatment to obtain a first water source.
Optionally, as shown in fig. 2, firstly, tap water (i.e., a water source to be filtered) is introduced into a urea machine as raw water, and is subjected to a pretreatment unit, and then is subjected to a treatment of pressurizing and introducing the raw water into a two-stage reverse osmosis treatment unit through a first-stage high-pressure pump and a second-stage high-pressure pump, so as to finally obtain a first water source, wherein the pretreatment unit mainly filters impurities with large particles in the water source to be filtered through a sand filtration module, a carbon filtration module, a softening module and an ultrafiltration module; the two-stage Reverse Osmosis treatment unit mainly comprises a first-stage RO (Reverse Osmosis) membrane and a second-stage RO membrane for filtering out impurities such as dissolved salts, colloids, bacteria, viruses and the like in a pretreated water source.
As can be seen from fig. 2, after the treatment by the two stages of reverse osmosis treatment units, the water purifier further detects whether the first water source meets the requirement of drinking water, that is, detects whether the conductivity of the first water source is smaller than the preset conductivity, wherein, when the conductivity of the first water source is greater than or equal to the preset conductivity, the water purifier is controlled to stop working, and alarm information is generated, and the alarm information can prompt a user to replace a filter element of the water purifier. Optionally, the water purifier has a conductivity instrument that detects the conductivity of the first water source.
Further, if it is detected that the conductivity of the first water source is less than a preset conductivity, the first water source is stored in an RO (Reverse Osmosis) tank, wherein the RO tank may be connected to a pure water tank for providing drinking water to a user, and when the amount of water in the ultrapure water tank reaches the preset amount of water, the water in the RO tank may be introduced into the pure water tank for providing drinking water to the user.
Specifically, under the condition that the water quantity in a preset water tank does not reach the preset water quantity, controlling the water purifier to execute a first water purification operation; and controlling the water purifier to perform a second water purification operation under the condition that the water amount in the preset water tank reaches the preset water amount.
When the water amount in the preset water tank does not reach the preset water amount, performing electric deionization operation on the first water source to obtain a third water source, performing heating operation on the third water source to obtain a second water source under the condition that the resistivity of the third water source meets the preset condition, and finally controlling a urea machine to stir the second water source and urea materials to generate urea solution.
Optionally, as shown in fig. 2, when the water amount in the ultrapure water tank does not reach the preset water amount, the water in the RO water tank is filtered by EDI (Electro Deionization) to obtain a third water source, and then a resistivity instrument is used to detect whether the resistivity of the third water source reaches the standard. If the resistivity of the third water source reaches the standard, the third water source is allowed to be led out to the ultrapure water tank; and if the resistivity of the third water source does not reach the standard, controlling the third water source to directly flow back to the RO water tank for circulation, and not allowing the third water source to be led out to the ultrapure water tank. Further, ultrapure water (namely a second water source) in the ultrapure water tank is heated by the heating module and then applied to a subsequent urea solution stirring unit, so that the second water source and the urea material are stirred, and finally the urea solution is obtained.
Optionally, as shown in fig. 2, when the amount of water in the ultrapure water tank reaches a preset amount of water, the water purifier performs pressurization processing on the first water source to obtain a fourth water source, then performs first filtration processing on the fourth water source to obtain a fifth water source, and finally performs sterilization processing on the fifth water source to obtain a drinking water source.
Specifically, when the water amount in the ultrapure water tank reaches the preset water amount, the RO water tank is controlled by the water purifier to be communicated with the EDI pipeline, the valve communicated with the pure water tank is closed, the valve communicated with the pure water tank is opened, and the water in the RO water tank is introduced into the pure water tank. The method comprises the steps of pressurizing pure water (namely a first water source) in a pure water tank by a variable-frequency water supply pump to obtain a fourth water source, filtering by a precision filter to obtain a fifth water source, and finally sterilizing by a flow type ultraviolet lamp to reach a water intake of a user of the water purifier to obtain the drinking water source.
It should be noted that the precision filter may include, but is not limited to, five pieces of 20 inch PP (rayon) cotton.
In addition, it should be noted that the urea machine is controlled to stop producing the urea solution before the water purifier is controlled to perform the second water purification operation. The urea solution's in-process is produced at the urea machine promptly, and drinking water is not produced to this purifier, stops to produce urea solution when the urea machine, and the drinking water is just produced to the purifier.
