Description

Technical Field

[0001] The utility model relates to the field of cooling tower water quality treatment, and more specifically, to a cooling tower water quality treatment device. Background Art

[0002] A cooling tower is a device used to cool circulating water in industrial production or air-conditioning systems. Hot water flows from industrial equipment or air-conditioning systems into the cooling tower. Inside the cooling tower, the hot water comes into contact with the air. On the one hand, the hot water increases its contact area with the air through spraying or filling. On the other hand, air is introduced into the cooling tower by a fan, forming a countercurrent or crosscurrent flow state with the hot water. In this process, the heat in the hot water is transferred to the air, the hot water temperature drops, and the air temperature rises and takes away the heat.

[0003] Chinese patent application number: CN202221277283.0, provides a water purification treatment device for a circular cooling tower. This solution can slow down the speed of water flow by inclination angle, so as to improve the filtration quality. The filter element A includes a foam breaking net, filter cotton, and filter net; the foam breaking net, filter cotton, and filter net are arranged in sequence from top to bottom. The foam is broken on the foam breaking net, which reduces the foam generated during the filtration process and further improves the filtration quality. However, during the filtration process, if there are impurities in the water, the impurities may block the filter holes when filtering the water flow, which is not conducive to the filtration of the water flow.

[0004] Therefore, in order to solve the above problems, a cooling tower water treatment device is proposed. Utility Model Content

[0037] Specific implementation process: First, the water in the cooling tower is introduced into the sand filter barrel 301 of the sand filter assembly 3 through the conical water inlet pipe cover 4. The water is filtered through sand of different particle sizes in the sand filter barrel 301. The large specific surface area and porosity of the sand can effectively remove impurities in the water. At the same time, the motor 303 in the protective cover 302 is started, and the motor 303 drives the transmission shaft 304 to rotate, thereby causing the blades 305 to turn over the sand in the sand filter barrel 301. This can prevent impurities from always adhering to specific parts of the sand layer, avoid local pore blockage of the sand, ensure that water can smoothly pass through the sand layer, and improve filtration efficiency. The water after sand filtration flows into the filter assembly 2 through the filter holes at the bottom of the sand filter barrel 301, and the water flow first contacts the diverter block 30 6. The water storage tank at the top of the diversion block 306 stores water to a certain extent, and then diverts the water in the water storage tank through multiple equidistantly arranged water guide grooves in the middle to prevent the water from gathering together when the water is discharged. The diverted water flows through multiple filters 202 that are equidistantly arranged up and down and with gaps gradually smaller from top to bottom. The filter screen 202 can perform multi-stage filtration on the water, filtering out suspended particles, impurities, etc. in the water step by step to prevent these substances from affecting the effect of chemicals and reducing the substrate for the growth of bacteria and algae. Finally, the water after multi-stage filtration by the filter component 2 flows into the shell 101 of the base component 1 and is discharged through the drain pipe 102 at the bottom of the shell 101, completing the treatment process of the cooling tower water quality.
