[0003] After the dust removal bag of the dust collector is used for a period of time, the dust removal effect of the dust removal bag of the dust collector is not very ideal due to the blockage of dust or the running time is too long, and it cannot meet the standards required by the country, so a large number of Replacing the dust bag of the dust collector is a very high investment. Now, cleaning technology can be used to clean the dust bag of the dust collector used in power plant boilers and other equipment. The effect is good and the cost is low. However, the dust bag is easy to be damaged after cleaning. A dust bag that does not need to be cleaned and will not be clogged

Abstract
The invention discloses a dust removal bag of an environmental-friendly dust collector. The dust removal bag is cylindrical, wherein the side surface of the dust removal bag is divided into an inner layer and an outer layer; the inner layer is made from a polytetrafluoroethylene filtration membrane; the outer layer is made from needled non-woven fabrics; a filtration material is arranged between the inner layer and the outer layer; the dust removal bag comprises an air inlet and an air outlet; a fixing base is arranged on the outer side of the air inlet; a metal filtration screen is arranged at the air outlet; at least one layer of filtration cloth is arranged between the air inlet and the air outlet; a circular air reversing interface is fixedly formed in the outer side of the metal filtration screen; at least two connection pipes are arranged in the air reversing interface; movable objects are arranged in the connection pipes; a steel wire mesh is arranged at the outmost end of the air reversing interface. The dust removal bag of the environmental-friendly dust collector is free of static electricity, high in tensile resistance, and has anti-corrosion and heat-resistant effects; dust is hard to stick to the dust removal bag; adsorbed dust can be shaken off by virtue of irregular movement of the movable objects in the air reversing interface under the action of wind; the dust removal bag is hard to block and is washing-free in long time; the frequency of demounting the filtration screen is reduced; and the working efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of dust removal, in particular to a dust removal bag of an environmental protection dust collector. Background technique [0002] Dust bag refers to the matching cloth bag in the bag filter, which is made of dust cloth. In the production process of thermal power generation, steel, and cement industries, a large amount of dust will be generated, which will cause serious pollution to the atmosphere. Therefore, the country Strict requirements are set for the atmospheric emissions of such enterprises, and bag dust removal is an ideal dust removal method widely used. The dust bag is called the heart of the bag filter and plays a very important role in the dust removal effect. [0003] After the dust removal bag of the dust collector is used for a period of time, the dust removal effect of the dust removal bag of the dust collector is not very ideal due to the blockage of dust or the running time is too long, and ...
