The air box pulse bag dust collector is a highly efficient dust removal equipment. Its manual usually contains the following key contents:
1. Overview
Air box pulse bag dust collector is widely used in cement, electric power, metallurgy and chemical industry. It combines the advantages of dust collectors of chamber reverse and jet pulse, and has the characteristics of advanced technology, excellent performance, strong adaptability, high dust collection efficiency and long service life of filter bags.
2. Introduction to the structure
The main components of air box pulse bag dust collector inculde: box body, bag chamber, ash hopper, air inlet and outlet, blowing system and cleaning controller.
① Box body: to fix bag cage, filter bag and air circuit components.
② Bag chamber: to hold bag cages and filter bags to form a filtering space.
③ Ash hopper: to store collected dust and serve as an air intake manifold.
④ Air inlet and outlet: according to the structure, they can divide into different types to ensure uniform distribution of airflow.
⑤ Blowing system: it includes pulse controller, solenoid pulse valve, blowing pipe and air bag.
3. Working principle
First, with dust-laden gas entering ash hopper from air inlet, coarse dust settles directly into ash hopper, and fine dust enters bag chamber with air flow. Next, in bag chamber, dust is retained by filter bag, while purified gas passes through filter bag into clean air chamber, and discharged from air outlet. Next, as filtration time passes, the dust on filter bag gradually increases, resulting in increase of resistance. At this time, dust cleaning controller triggers each control valve in sequence to open pulse valve, thus the compressed air in air bag is ejected instantly, then it induces surrounding clean air to enter filter bag. Finally, with filter bag expanding rapidly, the dust falls off, achieving the aim of dust cleaning.
4. Technical parameter
A. Filtration wind speed: it depends on factors such as dust property and dust concentration. The common recommended value is 1.25-1.5m/min.
B. Filter material selection: it includes polyester needle felt and nomex needle felt. It should depend on operating temperature and dust properties to choose the proper material.
C. Pulse cycle: it depends on factors such as: dust concentration in gas, filtration wind speed and air pressure for dust cleaning.
D. Gas consumption calculation: it relies on parameters of number of pulse valves, spraying time and pulse cycle.
5. Installation and debugging
❊ Before installation, check whether all accessories of the dust collector are complete, and whether the host is damaged.
❊ Install according to the instruction and ensure that all parts are tightly connected and well sealed.
❊ During debugging, check whether the control system operates normally, and adjust pulse period and pulse time to optimal state.
6. Maintenance
ⅰCheck the wear of the filter bags regularly and replace damaged ones in time.
ⅱ Clean the ash in the ash hopper to prevent blockage.
ⅲ Check the working status of each component of the injection system to ensure good cleaning effect.
ⅳ Regularly clean water separator to maintain the quality of compressed air.
7. Precautions
★ In practical application, ensure that the compressed air is clean and dry to avoid damage to filter bag.
★ Regularly inspect and maintain equipment to ensure long-term stable operation.
★ Follow safe operating rules to prevent accidents.
postscript
In actual application, air box pulse bag dust collectors can combine with grinding mill and classifying mill. It can effectively collect and handle the dust generated during operation of these equipment and reduce environmental pollution.
