Abstract

The present invention relates to a cooling system improved in terms of heat exchange (cooling) efficiency. In a body (100), coolant is supplied in a lower portion and air is circulated in an upper portion by means of a suction and discharge fan (120). Heated wastewater flowing into a heated wastewater inflow pipe (10) in the lower portion is subjected to heat exchange on a water-cooling basis by the coolant for primary heat exchange (cooling). Then, an air inflow partition wall is installed on a side surface for lateral air inflow, and a collision with air-cooling heat exchange occurs for upward discharge. Heat exchange (cooling) by means of secondary air and outward discharge are performed in this manner. The coolant is circulated and injected in the upper portion in the body. Then, evaporation heat resulting from contact with an air-cooling heat exchange pipe (13) is discharged to the outside for tertiary heat exchange (cooling). The heat-exchanged wastewater is discharged in this manner.

Description

Shatter-proof wastewater cooling system [0002]

The present invention relates to Scattering type wastewater cooling apparatus employing both a water-cooling system for cooling and an air-cooling system for cooling by air.

Generally, the cooling device can be divided into a water-cooling type and an air-cooling type according to the heat-dissipating type of the thermal medium. The water-cooled type cooling system is a system in which a heat medium is scattered in a cooling tower to dissipate heat. In the air-cooled type cooling system, a heat exchanger through which a heat medium flows is in contact with air to dissipate heat.

The water-cooled cooling system can cool the thermal medium to almost room temperature with minimal energy corresponding to the temperature change of the outside air.

The closed evaporation type cooling tower requires a shedding water tank, a water collecting tank, a pumping water pump, and the structure is complicated. In addition, since the supply source of the acid water is necessary, the installation place is limited. In addition, when water quality of the replenishing water is poor, or where the installation environment including dust, soot, and salt is bad, corrosion and scale are generated in the piping, and regular maintenance and inspection are troublesome.

On the other hand, the cooling system does not spray water on the heat transfer pipe, so it does not require a sump or a water tank. Accordingly, the air cooling type cooling system does not cause corrosion or scaling of the heat transfer tube by the arithmetic water, so that it is easier to repair than the water cooling type cooling system.

In addition, since a pump for supplying cooling water is not required, power consumption can be saved.

The conventional air cooling type cooler as described above has an advantage in that the gas refrigerant is phase-changed into the liquid refrigerant by passing air around the refrigerant pipe through which the gas refrigerant flows at a high temperature and a high pressure. However, A large number of pins must be installed on the outer surface of the pipe, and a blower of a large size is required. The air cooling type cooler is suitable for the cooling efficiency in the summer when the outside air temperature rises, but it can have a sufficient cooling effect even if the heat transfer area is substantially small in the season when the outside air temperature is low. , And since the cooler is larger than necessary in this way, the cost of raw materials is increased, handling is inconvenient, a lot of installation space is occupied, power consumption is increased, and so on. The odor is scattered and diffused when the wastewater is input and the wastewater is dropped downward from the upper side and contact heat exchanged with the air. In this case, the wastewater externally stays due to the influence of the strong fan, There is a problem of polluting the surrounding environment such as buildings,

On the other hand, the water-cooled type cooler is a type in which water (cooling water) is brought into contact with a refrigerant pipe, and the heat capacity of water is larger than that of air, so that the size of the cooler as a whole can be reduced. In order to secure the quantity of water, the cooling tower to be installed outdoors is very large and the water (cooling water) is transferred by the pump. Therefore, the construction cost is high and it is difficult to install in the existing building, It is a solution of the present invention that the cooler solves the problems that the cooling water volatilizes and splashes to the outside.

In order to solve the above problem, according to the present invention, cooling water is supplied to the inside of the body (100), and air is circulated by the intake / exhaust fan (120) The heating wastewater is heat-exchanged in a water-cooled manner by cooling water to perform primary heat exchange (cooling), and then an air inlet partition wall is provided on the side surface so that air is introduced from the side and collided with the air- Exchanged by the air and discharged to the outside, and the cooling water stored in the lower part of the inside of the body 100 is circulated and sprayed from the upper part inside the body to come in contact with the air-cooling type heat exchange tube 13 to discharge the generated heat of vaporization to the outside (Cooling) the heat exchanged wastewater, and the heat exchange (cooling) efficiency for discharging the heat-exchanged wastewater is increased, is a technical problem to be solved by the present invention.

The present invention adopts both a water-cooling method for cooling by water and an air-cooling method for cooling by air,

It is possible to cool products having various characteristics by using one cooling device, and in particular, it is possible to increase the heat exchange efficiency while alternately performing air cooling and water cooling, and the installation space of the cooling device is also reduced, .
