Abstract
How often does the dust bag need to be replaced? This question is a question that most customers will ask when customizing our company's dust bag. The service life of the filter bag is not universal. There is no suitable replacement time. Analyze actual usage. In the bag dust collector, the dust removal bag skeleton cloth cage is the core, the electromagnetic pulse valve controller is the auxiliary, and the dust removal bag is the important dust removal component of the whole dust removal system driven by the bag dust collector., In direct contact with harmful gases and dust, the flue gas is captured and filtered through filterability. If you want to extend the service life of the filter bag, you need to pay attention to the maintenance of the equipment, and you need to master the correct use and operation methods of the bag filter in the process of using the bag filter equipment. The dust bag gradually wears. The main causes of wear are the grinding force of dust, the deterioration of filter material caused by high temperature and the corrosion of chemical substances. When the grinding force of the dust is strong, the wear of the bag bottom is serious, and the increase of the system capacity will also accelerate the wear.
The dust collector cannot work with damaged cloth bags, otherwise it will accelerate the scrapping of the dust collector. When individual bags are damaged in a small area, you can use old bags or new filter cloth of the same material to repair the holes. The method of filling the holes is to bond with a silicone rubber compound. As long as the temperature and chemical properties can be adapted to the process conditions. Most of the bags are damaged when they should be replaced (when the filter material is working for a long time, the accumulated dust in the air filter material layer reduces the penetration and affects the air volume of the system, even if it is not damaged, it should be replaced), it is replaced when the bag filter stops working. At this time, the dust removal controller should be closed, the manhole door at the top should be opened, and the cloth bag should be removed. When disassembling, take out the bag cage first, and then put the cloth bag on it. Pinch the spring ring into a concave shape and pull up the cloth bag. Before installing the new cloth bag, clean the dust on the hole of the flower plate. In theory, the replacement cycle of the dust bag is 3-5 months. Under normal circumstances, except for special end high temperature and high sulfur conditions, most conditions are replaced once a year.

The structure of high temperature bag type dust collector is mainly composed of upper box body, middle box body, lower box body (ash hopper), ash cleaning system and ash release mechanism.
Commonly used cleaning methods are:
1. Mechanical knockout: divided into upper knockout and middle knockout (filter bag knockout). The mechanical percussion device periodically knocks each row of filter bags in turn to remove the filter bags. Dust on the bag.
2. Manual tapping: each filter bag is manually tapped to remove the dust on the filter bag.
3. Gas cleaning: Gas cleaning is by high pressure gas.
