AI Technical Summary

Technical Problem

Existing evaporative condensers are not good at filtering water entering the spray pipe, which leads to the accumulation of impurities and blockage of the pipe, affecting the working efficiency of the condenser.

Method used

A counter-flow evaporative condenser was designed, which adopts a filter box and a three-way ball valve structure. The filter box is equipped with multiple filter plates. The water flow direction is switched by the three-way ball valve to achieve water filtration and cleaning, and prevent impurities from entering the water spray pipe.

Benefits of technology

It effectively prevents impurities from entering the water spray pipe and causing blockage, ensuring the normal working efficiency of the condenser. The design of the filter box and three-way ball valve makes water filtration and cleaning convenient.

Abstract

The utility model discloses a reverse flow type evaporative condenser, and particularly relates to the technical field of condensers, which comprises a condenser shell, a supplement pipe arranged on one side of the outer surface of the condenser shell and a water pump arranged on one side of the outer surface of the condenser shell, and a water delivery pipe is fixedly connected between an inlet of the water pump and the condenser shell. And a transmission pipe is fixedly mounted at an outlet of the water pump. According to the reverse flow type evaporative condenser, in actual work, water in the condenser shell can pass through the filtering box when being conveyed into the water spraying pipe in the condenser shell through the water pump, impurities in the water can be filtered out through the three filtering plates in the filtering box, the water conveying direction can be controlled through the three-way ball valve, and therefore the water conveying direction can be controlled, and the water conveying direction can be controlled. And when one filter box is shut down for cleaning, the other filter box can replace the filter box for operation, so that water entering the water spraying pipe is conveniently filtered, and the situation that impurities enter the water spraying pipe to cause blockage of the water spraying pipe, and consequently the working efficiency of the condenser is affected is effectively avoided.
