Problems solved by technology

Since the filter bag may attach or breed bacteria in the filtering process, and it is difficult to effectively inhibit the bacteria in the dust cleaning process, so during the service life of the filter bag, although the filtering operation can still be performed, the dust gas after filtration is safe. decreased

Abstract

The invention relates to a filtering bag capable of generating negative ions. The filtering bag comprises a bag body, wherein the bag body has a bottom part; the bottom part comprises a dust receiving layer, a middle layer and a base cloth layer in sequence from outside to inside; a containing cavity is formed between the middle layer and the base cloth layer; air vents are formed in the surface of the containing cavity; and negative ion powder is stored in the containing cavity. According to the filtering bag provided by the technical scheme, inverted airflow enters the containing cavity in an ash cleaning operation process; and when the inverted airflow is generated intermittently, the containing cavity is repeatedly expanded and retracted in a gap layer and the negative ion powder in the containing cavity is carried by the airflow to enter the bag body, so that the inside of the bag body is subjected to virus killing and sterilization by the negative ions. The invention further provides a filtering material of the filtering bag; a polytetrafluoroethylene film is adopted for the dust receiving layer; the middle layer is formed by blending polyester staple fibers and polyester filaments; and the base cloth layer is formed by mutually hooking glass fibers and carbon fibers.

Description

technical field [0001] The invention relates to a filter bag, in particular to a filter bag capable of generating negative ions; the invention also provides a filter material of the filter bag, which belongs to the technical field of environmental protection equipment. Background technique [0002] The filter bag is a key part in the operation of the bag filter, and the cylindrical filter bag is usually hung vertically in the filter bag. The fabric and design of the filter bag should be as efficient as possible, easy to remove dust and durable. In the pulse and air box pulse dust collector, the dust is attached to the outer surface of the filter bag. When the dusty gas passes through the dust collector, the dust is collected on the outer surface of the filter bag, and the clean gas enters the inside of the filter bag through the filter material. The skeleton inside the filter bag is used to support the filter bag and prevent the filter bag from collapsing. [0003] After ...
