Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, and more specifically, to a sewage discharge device for a cooling tower. Background Technique

[0002] In industry, a cooling tower uses water as a circulating coolant. Its cooling utilizes the principle of heat exchange between water and air flow contact to generate steam, and the evaporation of steam takes away heat to achieve evaporation heat dissipation, convective heat transfer, and radiative heat transfer, etc., to dissipate the waste heat generated in industry or refrigeration and air conditioning to reduce the water temperature. An evaporation heat dissipation device is used to ensure the normal operation of the system and requires sewage discharge treatment for clean water quality.

[0003] In the prior art, the patent document with the publication number CN217877299U provides a sewage discharge device for a cooling tower. The device uses the cooperation of a sewage discharge tank, a top shell, bolts, a skeleton, a filter cartridge, a downpipe, etc. The filter cartridge in the sewage discharge tank adsorbs impurities in the water. Clean water is injected into the top shell through a curved pipe. The clean water enters the cavity of the skeleton and seeps out through the filter cartridge, which can clean the impurities remaining on the surface of the filter cartridge. The valve of the downpipe is opened to discharge sewage, and the filter cartridge is cleaned using the principle of backwashing.

[0004] Although this method has many beneficial effects, there are still the following problems: directly discharging the cooling water into the sewage pipe for filtration treatment, algae growth and sludge accumulation will occur inside the cooling tower after long-term use. Direct filtration is likely to cause blockage of the filtration pipeline. Using the backwashing principle to clean the filter cartridge, impurities will still adsorb on the surface of the filter cartridge after long-term use, resulting in a decline in the filtration effect; secondly, replacing the filter cartridge is cumbersome and the filtration device needs to be disassembled.
