A pps modified acid and alkali resistant high temperature resistant oxidation resistant dust filter bag

Abstract

The invention provides a PPS modified acid and alkali resistant, high temperature and oxidation resistant dust removal filter bag, which relates to the technical field of industrial environmental protection, comprising an inner layer of a dust removal filter bag and an outer layer of a dust removal filter bag, and the outer layer of the dust removal filter bag is sleeved in the dust removal filter bag Outside the outer layer, the inner layer of the dust filter bag and the top of the outer layer of the dust filter bag are respectively provided with an outer bag mouth and an inner bag mouth, the outer bag mouth and the inner bag mouth are flush, and the outer bag mouth and the inner bag mouth are fixed. There is a support frame for the pocket mouth, a reinforcement bag fixing ring is fixedly arranged on the pocket mouth support frame, a reinforcement bag is movable on the reinforcement bag fixing ring, and the reinforcement bag fixing ring includes a fixing ring body, and the fixing ring body is fixedly arranged on the pocket mouth supporting frame , the fixed ring body is a ring structure, and the cross section of the fixed ring body is rectangular, and the fixed ring body is provided with breakpoints. The invention has the advantages of avoiding the collapsing phenomenon during use and improving the cleaning efficiency.

Description

technical field [0001] The invention relates to the technical field of industrial environmental protection, in particular to a PPS modified acid and alkali resistant high temperature resistant oxidation resistant dust removal filter bag. Background technique [0002] At present, the commonly used dust filter bag is cylindrical, with an open top and a closed (or open) bottom. When the dust filter bag is in working condition, the airflow blows from the inside of the dust filter bag to the outside. The dust filter bag itself is always in a cylindrical bulging state under the action of the airflow. However, when the wind is turned off or the airflow is not sufficient, the dust filter bag is prone to collapse, that is, the inner walls of the dust filter bag are bonded together, which is likely to cause incomplete dust removal. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a PPS modified acid and alkali resistant h...
