Overview
The bag dust collector is mainly composed of four major systems. These are the dust cleaning system, the control system, the inspection system, and the safety protection system. The safety protection system includes boiler ignition and oiling, a pre-coating system for low-load operation, and a stable combustion filter protection system. When the smoke temperature exceeds the set value, the emergency water spray system starts to reduce the smoke temperature and protect the filter bag.
The ash cleaning system acts as the digestive organ of the bag dust collector. The operating effect of the bag dust collector largely depends on the dust cleaning mechanism and its control system.
Working principle
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 surface outside the filter bag blocks the dust.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 newly long bag dust collector is efficient and builds upon the conventional short bag pulse dust collector.
This design integrates chamber backflush and pulse cleaning. It overcomes the shortcomings of insufficient backflush intensity in ordinary chambers and the re-attachment of dust in general pulse cleaning. The filter bag is lengthened to maximize the powerful cleaning effect of compressed air.
The dust collector is large-scale equipment that offers high dust removal efficiency, a small footprint, stable operation, reliable performance, and easy maintenance. It finds widespread application in industries such as metallurgy, casting, building materials, mining, and chemical processing.
Performance characteristics
The inlet and outlet air ducts are compactly arranged, resulting in small airflow resistance. The system uses pulse jet dust cleaning technology, which provides strong dust cleaning ability and high dust removal efficiency. It also features low emission concentration, a small air leakage rate, and low energy consumption.
Additionally, it has low steel consumption and a small footprint. The operation is stable and reliable, delivering good economic benefits.
This dust collector is suitable for flue gas dust removal in industries such as metallurgy, building materials, machinery, chemical processing, electric power, and light industry.
The box body adopts an airtight design, ensuring good sealing performance. Darko constructs the inspection door using excellent sealing materials. We use kerosene to detect leaks during production, resulting in a very low air leakage rate.
When dust-containing gas passes through the fibers of the filter cloth, dust particles larger than 1 μm maintain linear motion due to inertia. These particles hit the fibers and get captured. The larger the diameter of the dust particles, the greater their 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.
