Simple filtering device for air conditioner circulating water system and use method for simple filtering device

Abstract

The invention provides a simple filtering device for an air conditioner circulating water system and a use method for the simple filtering device. The device comprises a branch pipe for connecting anair conditioner water supply pipe with an air conditioner water return pipe as well as a first cutoff valve, a filter and a second cutoff valve which are sequentially arranged on the branch pipe, wherein one end of the branch pipe is connected with the air conditioner water supply pipe through a precipitator; the other end of the branch pipe is connected with the air conditioner water return pipe;the precipitator is arranged at the bottom of the air conditioner water supply pipe; the bottom of the filter is connected with a blow-off pipe; a blow-down valve is arranged on the blow-off pipe. Byarranging the precipitator at the bottom of the air conditioner water supply pipe, impurities are deposited in the precipitator when air conditioner circulating water flowing in the air conditioner water supply pipe passes through the upper part of the precipitator, and further the impurities accumulated in the precipitator are driven by the air conditioner circulating water to be incepted in thefilter, and the problems of low operation efficiency, high operation energy consumption, equipment damage and the like of an air conditioner system caused by excessive impurities inside the air conditioner circulating water system are avoided.

Description

technical field [0001] The invention relates to the field of air-conditioning circulating water systems, in particular to a simple filter device for air-conditioning circulating water systems and a method for using the same. Background technique [0002] During the construction of the air-conditioning circulating water pipeline, it is inevitable that sand, gravel, iron filings, welding slag, hemp silk and other sundries will fall into the pipeline and remain on the bottom layer of the inner wall of the pipeline. At the same time, the iron oxide remaining on the inner wall of the pipeline due to oxidation and corrosion will also fall off and deposit inside the pipeline. [0003] Before the pipe network is put into operation, these impurities must be removed, otherwise it will cause low operating efficiency of the air conditioning system, increased operating energy consumption, and even more serious equipment damage. [0004] Therefore, how to provide a simple filter device f...
