The bag dust collector is mainly composed of four major systems, namely the dust cleaning system, the control system, the inspection system, and the safety protection system (including boiler ignition and oiling, pre-coating system when the oil is added for low-load operation and stable combustion, and filter protection system). bag; when the smoke temperature exceeds the set value, the emergency water spray system is started to reduce the smoke temperature and protect the filter bag. The ash cleaning system is the digestive organ of the bag dust collector, and the operating effect of the bag dust collector depends to a large extent. In the dust cleaning mechanism and its control system.

Working principle of bag dust collector:

Bag dust collector is a filter-type dust removal equipment based on the filtration principle. It uses agricultural production system fiber or inorganic fiber filter cloth to filter out the dust in the gas. Dust removal process: Dust-containing gas enters the middle box from the air inlet and enters the bag from outside the filter bag. The dust is blocked on the surface outside the filter bag. The purified air enters the bag and then enters the upper box from the upper part of the bag. Expelled from the exhaust pipe. The large pulse long bag dust collector draws on advanced domestic and foreign technologies. The new and efficient long bag dust collector successfully developed is a new and efficient type developed on the basis of the conventional short bag pulse dust collector. It not only integrates chamber backflush and The characteristics of pulse cleaning overcome the shortcomings of insufficient backflush intensity of ordinary chambers and the re-attachment of dust in general pulse cleaning, and the filter bag is lengthened to give full play to the powerful cleaning effect of compressed air. It is a large-scale dust removal equipment with high dust removal efficiency, small footprint, stable operation, reliable performance and easy maintenance. It can be widely used in metallurgy, casting, building materials, mining, chemical industry and other industries. Performance characteristics: The inlet and outlet air ducts are compactly arranged and the air flow resistance is small. Using pulse jet dust cleaning technology, it has strong dust cleaning ability, high dust removal efficiency, low emission concentration, small air leakage rate, low energy consumption, low steel consumption, small floor space, stable and reliable operation, and good economic benefits. Suitable for flue gas dust removal in metallurgy, building materials, machinery, chemical industry, electric power and light industry. The box body adopts an air-tight design with good sealing performance. The inspection door is made of excellent sealing materials. Kerosene is used to detect leaks during the production process, so the air leakage rate is very low.

When dust-containing gas passes through the fibers of the filter cloth, dust larger than 1 μm still maintains linear motion due to inertia and hits the fibers and is captured. The larger the diameter of the dust particles, the greater the inertial effect. The higher the filtration air speed, the greater the inertial effect. However, if the air speed is too high, the air volume passing through the filter cloth will also increase, and the air flow will penetrate the weak points of the filter cloth, resulting in a reduction in dust removal efficiency. The higher the gas speed, the more serious the puncture phenomenon will be.
