A bag filter is a filtration-based dust removal device that uses organic or inorganic fiber filters to remove dust from gases. Dust removal process: The dust-containing gas enters the middle chamber through the inlet, passes from outside the filter bags into their interior; the dust is trapped on the surface outside the filter bags, while the cleaned air enters the filter bags. From there, it moves upward to the upper chamber and is finally discharged through the exhaust pipe. A bag filter is a type of large-scale dust removal equipment with high efficiency in removing dust, low space requirements, stable operation, reliable performance, and easy maintenance. It can be widely used in industries such as metallurgy, foundry, building materials, mining, and chemicals, and it operates on the principle of filtration. The entire bag filter uses organic or inorganic fiber filter cloth to remove dust from the gas. Dust removal process of the bag filter: Dusty gas enters the middle chamber through the inlet, passes inside the bags from the outside, with the dust remaining on the surface outside the filter bags. The cleaned air enters the bags and then moves to the upper chamber via the top of the bags, before being discharged through the exhaust pipe. The large-scale pulse long-bag dust collector is a new type of high-efficiency long-bag dust collector developed by drawing on advanced technologies from home and abroad. It represents a novel and efficient bag-type dust collector that has evolved from conventional short-bag pulse dust collectors. It not only combines the advantages of chamber reverse blowing and pulse cleaning, overcoming the shortcomings of insufficient cleaning intensity in ordinary chamber reverse blowing as well as dust re-deposition in typical pulse cleaning methods, but also features longer filter bags, thereby making full use of the powerful cleaning effect of compressed air. Performance features of the bag filter: It features a novel design with an air inlet structure that allows larger, high-temperature particles to fall directly into the ash hopper, thereby effectively protecting the filter bags. The entire equipment is controlled by a PLC, enabling automatic ash cleaning, ash discharge, automatic temperature control, and over-temperature alarm. By using long filter bags, the equipment occupies less space at the same processing capacity, making it easier to upgrade existing plants. The filter bag opening features a spring-tightening structure, which facilitates installation and removal and ensures good sealing performance. The use of a chamber-separated line for dust removal ensures high efficiency, reduces secondary dust adsorption, and simultaneously lowers the energy consumption of the equipment. It also decreases the wear and fatigue of the filter bags and pulse valves, thereby significantly extending their lifespan and greatly reducing the costs associated with equipment operation and maintenance.
