AI Technical Summary
The existing method of cleaning the screens in the circulating water passageway is labor-intensive, and debris is easily dislodged during the cleaning process and enters the circulating water pump and heat exchanger, leading to equipment failure and unstable system operation.
The system uses a combination of a first grid and a second grid to separate and intercept debris by size. The inclined design and guide rail structure facilitate cleaning. After the debris falls off, it enters the interception grid and support grid, where it is further intercepted by a rake to prevent it from entering the circulating water system.
It achieves comprehensive interception and convenient cleaning of debris, preventing debris from entering the circulating water pump and heat exchanger, ensuring the safe and stable operation of the system, and reducing the risk of equipment failure.
