Full-automatic back-flush filtering system

Abstract

The invention discloses a full-automatic back-flush filtering system which comprises an emptying tank, a nitrogen tank, a pollution receiving tank, a first multi-channel rotating valve, a second multi-channel rotating valve and a plurality of filters, wherein the bottoms of the plurality of filters are communicated with a filtrate inlet pipe through the second multi-channel rotating valve; the tops of the plurality of filters are communicated with a filtrate outlet pipe through the first multi-channel rotating valve; the first multi-channel rotating valve is connected with the emptying tank through a coupling valve; a filtered coupling valve connected with the first multi-channel rotating valve in parallel is arranged between the coupling valve and the filtrate outlet pipe; the emptying tank is connected with the nitrogen tank; the second multi-channel rotating valve is connected with a soaking inlet pipe and the pollution receiving tank; a fluid infusion filtering valve connected with the second multi-channel rotating valve in parallel is arranged between the soaking inlet pipe and the filtrate inlet pipe; the pollution receiving tank is communicated with the emptying tank; a differential pressure transmitter is arranged between the filtrate outlet pipe and the filtrate inlet pipe. According to the system disclosed by the invention, the back-flushing efficiency can be improved, the degree of automation is high, centralized monitoring is facilitated, and unattended full-automatic operation can be realized.

Description

technical field [0001] The invention relates to filtering equipment, in particular to a fully automatic backwashing filtering system. Background technique [0002] The traditional filter system has a small amount of dirt and is easily blocked by dirt. The filter part needs to be disassembled and cleaned, which has great limitations and is difficult to operate and maintain. It is also not effectively monitored, and the degree of automation is not high. Contents of the invention [0003] In order to solve the above problems, the present invention provides a fully automatic backwashing filter system, which has high backwashing efficiency and automation, and can be monitored centrally. [0004] The present invention adopts the following technical solutions: a full-automatic backwashing filter system, including an empty tank, a nitrogen tank, a dirt tank, a first multi-channel rotary valve, a second multi-channel rotary valve and a plurality of filters arranged side by side. ...
