Abstract

The invention discloses an elastomer corrugated filter tube. Metal sintered felt is coiled to form a cylindrical tubular filter element, the surface of the filter element is provided with a plurality of grooves and raised lines extending along the axial direction, the external tubular surface of the filter element is provided with the grooves and the raised lines alternately, and each raised line serves as a connection part of two adjacent grooves. The elastomer corrugated filter tube is greatly suitable for gas-solid and gas-liquid separation occasions. During the use process of the elastomer corrugated filter tube, gas with impurities impacts the grooves and the raised lines, dust in the gas with impurities falls or gathers in the grooves, the raised lines can keep good filtering performance continuously, and when the dirt holding quantity of the filter element reaches a certain limit, dirt can be cleaned in a backwashing type sound wave manner, a vibrating manner and other manners so as to recover the filter capacity. According to the invention, the metal sintered felt can be further directly prefabricated into an elastic corrugated plate sheet, the grooves and the raised lines can be in an arc transition state, and thus fatigue failure can be effectively prevented.

Description

technical field

[0001] The invention relates to the technical field of structural design of gas-solid and gas-liquid filter elements, in particular to an elastic body corrugated filter tube. Background technique

[0002] At present, for dust filtration, bag filter is mostly used. The bag filter is a dry dust filter device, which is suitable for collecting fine, dry, non-fibrous dust. The filter tube used is generally a filter bag with a cloth bag structure. It is made of cloth or non-woven felt, and uses the filtering effect of the fiber fabric to filter the impurity gas. When the impurity gas enters the bag filter, the dust with large particles and specific gravity will settle down due to the action of gravity and fall into the bag filter. When the gas containing fine dust passes through the filter bag, the dust will be blocked and the gas will be purified.

[0003] The filter tubes of the existing filter bag structure are all made of polymers, the processing procedures a...
