Frameless natural gas filter element structure and mounting and fixing method

Abstract

The invention discloses a frameless natural gas filter element structure and a mounting and fixing method and belongs to the technical field of machinery. An upper end cover of the filter element is in a blind cover form; a lower end cover of the filter element is in a circular hole form; the lower end cover is provided with a sealing ring groove; the sealing ring groove is connected with an O-shaped sealing ring; a lower bonding groove is formed in the upper end surface of the lower end cover; the lower end cover and the filter layer are bonded by the lower bonding groove; and the lower end cover is connected with a core base. The upper end cover of the filter element comprises a handle, an end cover and a filter element positioning disc, wherein the handle is connected with the filter element positioning disc; the other surface of the filter element positioning disc is connected with the end cover; an upper bonding groove is formed in the lower end surface of the upper end cover; theupper end cover is bonded with the filter layer through the upper bonding groove in a hot melting manner; a pipe plate is connected with a branch pipe; the outer circumference of the other end of thebranch pipe is connected with the core base and the framework, and an inner cavity of the other end of the branch pipe is connected with a rear supporting rib plate; a central screw hole of the rearsupporting rib plate is connected with a pull rod; an inner cavity of the framework is connected with a front supporting rib plate, and a central circular hole of the front supporting rib plate is connected with the other end of the pull rod; and a center connecting tie rod is connected to the front supporting rebar plate through a fastening nut

Description

technical field [0001] The invention relates to a frameless natural gas filter element structure and an installation and fixing method, belonging to the technical field of machinery. Background technique [0002] Natural gas filter separators are widely used in long-distance natural gas pipelines. They are mainly used to remove solid dust impurities and large liquid droplets in natural gas. They play a very important role in protecting important equipment such as compressors, gas turbines and flow meters. The filter separator is equipped with a large number of natural gas filter elements, which are the key units for intercepting dust and removing impurities. After the natural gas filter element has been used for a period of time, when the replacement pressure difference is reached, the filter element needs to be replaced. Therefore, the maintenance personnel of the natural gas station need to replace the filter element every year. [0003] The existing natural gas filter s...
