Anti-blocking type gas filter

Abstract

The invention provides an anti-blocking type gas filter which is provided with a cylindrical filter body. The filter body is internally provided with a first vertical screen plate, a second vertical screen plate and a third vertical screen plate, wherein the first vertical screen plate, the second vertical screen plate and the third vertical screen plate are arranged at intervals along the radial direction of the filter body; an inner cavity of the filter body is divided into a first cavity, a second cavity, a third cavity and a fourth cavity, wherein a first filter screen, a second filter screen, a third filter screen and a fourth filter screen are correspondingly placed in the first cavity, the second cavity, the third cavity and the fourth cavity, and the mesh numbers of the first filter screen to the fourth filter screen are gradually increased; four openings are formed in the bottom of the filter body at intervals, the openings correspond to the first cavity, the second cavity, the third cavity and the fourth cavity, and sealing plates are respectively arranged on the openings in a covering way; the mesh aperture of the second vertical screen plate is smaller than the mesh aperture of the first vertical screen plate and larger than the mesh aperture of the third vertical screen plate.

Description

technical field [0001] The invention belongs to the field of oil and gas exploitation, and in particular relates to an anti-blocking gas filter used on a gas pipeline. Background technique [0002] At present, the filter element of the filter used on the gas pipeline is often blocked by various impurities (sand, iron blocks and other foreign objects) in the gas, and the filtering effect is also very general, and after the blockage, It is very difficult to clean the filter element, which affects the work efficiency. [0003] In view of this, the inventor has developed an anti-clogging gas filter based on years of experience in production design in this field and related fields, in order to solve the problems existing in the prior art. Contents of the invention [0004] The purpose of the present invention is to provide an anti-clogging gas filter, which can filter the gas from coarse to fine, can effectively filter out impurities, and is convenient for cleaning various sun...
