Abstract

The invention discloses an automatic filter core cleaning and sewage discharge system suitable for gas filters, and relates to the technical field of gas filters. The present invention includes a gas filter, which includes a cylinder body, a flange cover, a filter element, a gas inlet, a gas outlet, and a sewage outlet; Valve, rotary driver, rotator and differential pressure transmitter; the filter element is placed in the rotator, and a connecting pipe is arranged at the bottom of the rotator, which communicates with the inner cavity of the filter element. The outlet is sealed and connected with a sealed structure. The invention can realize the conversion of high-pressure air flow from the normal working state to the reverse flow of air flow, so as to realize the back blowing of the filter element, achieve the effect of automatic filter element cleaning and sewage discharge, and have a high degree of automation.

Description

technical field [0001] The invention relates to the technical field of gas filters, in particular to an automatic filter core cleaning and sewage discharge system suitable for gas filters. Background technique [0002] At present, the filters used in gas chemical industry mainly use such as figure 1 The structure shown includes flange cover, filter element, cylinder body, gas outlet, sewage outlet, differential pressure gauge and gas inlet. Set in the cylinder, the inner cavity of the filter element communicates with the gas outlet. The working principle of the filter is: the gas enters the barrel through the gas inlet, and is discharged from the gas outlet after being filtered by the filter element. Use for a certain period of time, and the differential pressure gauge shows that the pressure difference reaches the specified value, you need to switch to another set of filters, and then close the filter for manual cleaning. When cleaning, it is necessary to disassemble the...
