A method for integrating the net ring side filter water supply pump group and the net ring water supply pump group

Abstract

The invention relates to a method for integrating a clean circulating side-filtration water supply pump set and a clean circulating water supply pump set. A clean circulating cooling water system comprises a clean circulating cooling water suction well, a plurality of clean circulating water supply pump sets, a bypass filter and a clean circulating cooling tower. In order to remove impurities brought into the system in the circulation cooling process, the bypass filter is arranged; one pump set with the pressure grade the same as or close to that of the clean circulating side-filtration water supply pump set is selected from the clean circulating water supply pump sets, the two pump sets are integrated, and then the integrated pump set is used so that the clean circulating water supply function and the bypass filtration function can be achieved at the same time. A branch pipe is branched from a clean circulating cooling water supply pipe of the integrated pump set for the bypass filter, and water filtered by the bypass filter flows back to the clean circulating cooling water suction well through a filtered water return pipe. By means of the method, the clean circulating side-filtration water supply pump set and the clean circulating water supply pump set are integrated, the technological process is simple and smooth, operations are stable, investment is small, the occupied area is saved, the production and maintenance cost is greatly reduced, the maintenance period is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention relates to an industrial clean ring cooling water system, in particular to a method for integrating a clean ring side filter water supply pump set and a clean ring water supply pump set. Background technique [0002] At present, the water supply pump group of the net bypass filter generally adopts a separate group of water pumps (one working and one standby) to complete the function of the net bypass filter, such as figure 1 As shown, the net ring cooling water system is composed of a net ring cold water suction well, a net ring side filter water supply pump set, pipes and valves, multiple clean ring water supply pump sets, bypass filters and a clean ring cooling tower; each pump set consists of A plurality of water pumps are connected in parallel, and valves are set on each parallel branch; the net ring water supply pump group is connected to the net ring water user through the net ring cooling water supply pipe, and then connected to th...
