Abstract

The invention provides a PPS modified acid-base-resistant high-temperature-resistant oxidation-resistant dust removal filter bag and relates to the technical field of industrial environmental protection. The dust removal filter bag comprises a dust removal filter bag inner layer and a dust removal filter bag outer layer, the dust removal filter bag outer layer sleeves the dust removal filter bag inner layer, an outer bag opening and an inner bag opening are respectively formed in the tops of the dust removal filter bag inner layer and the dust removal filter bag outer layer, the outer bag opening is flush with the inner bag opening, a bag opening supporting framework is fixedly arranged between the outer bag opening and the inner bag opening, a reinforcing bag fixing ring is fixedly arranged on the bag opening supporting framework, a reinforcing bag is movably arranged on the reinforcing bag fixing ring, the reinforcing bag fixing ring comprises a fixing ring body, the fixing ring bodyis fixedly arranged on the bag opening supporting framework, the fixing ring body is of an annular structure, the section of the fixing ring body is rectangular, and breakpoints are arranged on the fixing ring body. The dust removal filter bag has the advantages that the collapse phenomenon in use is avoided and the ash removal efficiency is improved.

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...
