Open-type circulating water bypass filtration apparatus and circulating water treatment method utilizing same

Abstract

The invention provides an open-type circulating water bypass filtration apparatus and a circulating water treatment method utilizing same. The apparatus comprises a first filter, a second filter, a dosing tank, a dosing pump and corresponding connecting pipelines and valves. The circulating water treatment method comprises a filter step, a backwashing step and a dosing step. The circulating water bypass filtration apparatus adopts an advanced filtering, backwashing and dosing process, two filters can be switched to use, the medicine soaking and clean water backwashing can be carried out online, and the 24-hour continuous operation can be realized.

Description

technical field [0001] The invention relates to an open circulating water bypass filter device and a circulating water treatment method using the same, in particular to an open circulating water bypass filter device and a circulating water treatment method using a tubular ceramic membrane as a filter element. Background technique [0002] In the industrial field, the circulating cooling water system is divided into a closed circulating water system and an open circulating water system. The open circulating water system has been widely used due to its low investment and convenient maintenance. During the operation of the open circulating water system, there is a large amount of suspended solids, especially in the cooling water. Due to the entry of dust and debris in the air, some scale, rust, and microbial slime will fall off and disperse after daily dosing treatment, resulting in turbidity of the water quality, resulting in pipeline blockage or affecting the performance of ...

AI Technical Summary

Problems solved by technology

[0005] The invention provides an open circulating water side filter device, which can solve the problems of hardening, twisting, large running resistance, long backwashing time and low filtration efficiency of the filter material caused by the existence of slime and suspended matter in the circulating cooling water filtration process. The problem is to ensure the turbidity requirements of open circulating water and achieve the effect of closed circulating water. The anti-collision structure of the filter can prevent the filter from colliding and breaking during transportation, installation and disassembly.
