Long bag low pressure spray dust collector

Product Introduction: JDMC series large pulse long bag dust collector is a new type of high-efficiency long bag dust collector successfully developed by our company's technical personnel by drawing on advanced dust removal technology at home and abroad. It not only combines the advantages of chamber backblowing and pulse cleaning, but also overcomes the shortcomings of insufficient strength of ordinary chamber backblowing and dust reattachment of general pulse cleaning. In addition, the filter bag is lengthened to give full play to the role of compressed air in strong cleaning. 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, electric power, building materials, mining, chemical industry and other industries.
Application areas: Applied in building materials, metallurgy, machinery, electricity, chemical industry and other industries

    Product Introduction

    JDMC series large pulse long bag dust collector is a new type of high-efficiency long bag dust collector successfully developed by our company's technical personnel by drawing on advanced dust removal technology at home and abroad. It not only combines the advantages of chamber backblowing and pulse cleaning, but also overcomes the shortcomings of insufficient strength of ordinary chamber backblowing and dust reattachment of general pulse cleaning. In addition, the filter bag is lengthened to give full play to the role of compressed air in strong cleaning. 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, electric power, building materials, mining, chemical industry and other industries.

    Outstanding advantages

    ● 1. Pulse jet cleaning technology is adopted, which has strong cleaning ability, high dust removal efficiency, low emission concentration, small air leakage rate, low energy consumption, small footprint, stable and reliable operation, and good economic benefits. It is suitable for flue gas dust removal in metallurgy, building materials, cement, machinery, chemical industry, electric power, and light industry.
    ● 2. The box body adopts airtight design with good sealing performance. The inspection door uses excellent sealing materials and the air leakage rate is very low.
    ● 3. The inlet and outlet air ducts are compactly arranged with small air flow resistance.
    ● 4. It adopts chamber-by-chamber air-stop pulse jet cleaning, which has a long cleaning cycle and low consumption, and can multiply the life of the filter bag and valve plate.
    ● 5. Bag replacement can be achieved without stopping the machine, and maintenance will not affect the normal operation of the equipment.
    ● 6. The upper bag extraction method is adopted to improve the operating conditions for bag changing.

    How it works

    JDMC pulse long bag dust collector is composed of ash hopper, upper box, middle box, lower box and other parts. The upper, middle and lower boxes are chamber structures. When working, dusty gas enters the ash hopper from the air inlet duct, coarse dust particles fall directly into the bottom of the ash hopper, and fine dust particles enter the middle and lower boxes upward with the turning of air flow. Dust accumulates on the outer surface of the filter bag, and the filtered gas enters the upper box to the clean air collection room - the exhaust duct, and is discharged to the atmosphere through the exhaust fan.

    The cleaning process is to first cut off the clean air outlet duct of the room, so that the bag in the room is in a state of no airflow (cleaning by stopping air in each room). Then open the pulse valve to use compressed air for pulse spraying and cleaning. The closing time of the cut-off valve is to ensure that the dust peeled off from the filter bag after spraying settles in the ash hopper, avoiding the phenomenon that the dust is attached to the surface of the adjacent filter bag with the gas flow after leaving the surface of the filter bag, so that the filter bag is cleaned thoroughly, and the lifting valve and pulse valve are fully automatically controlled by the programmable controller.

    Note: 1. The air volume in the table is calculated based on the filtration wind speed of 1.0-1.5m/min. If the user requires, it can be reduced or increased according to the specific situation.

    2. The filtration area is calculated based on the filter bag length of 6m. If the user requires, the filter bag can be lowered or appropriately lengthened to reduce or appropriately increase the filtration area.
