Introduction

Long Bag Offline Pulse Dust Collector lefilter

Long Bag Offline Pulse Dust Collector

LCM type long-bag pulse dust collector is a new type of high-efficiency bag-type dust collector developed on the basis of conventional short-bag pulse dust collector. It not only combines the advantages of sub-chamber backflushing and pulse jet cleaning, but also lengthens the bag to give full play to the powerful jet cleaning of compressed air. It overcomes the shortcomings of low intensity of backflushing in separate chambers, and simultaneous pulse jet cleaning and dust filtration, and prevents the problem of dust reattachment and out-of-control, thereby increasing the filtration speed, saving energy consumption for cleaning and prolonging the life of the filter bag. . The electric control of the dust collector adopts advanced PLC programmable controller.

Application Mechanical equipment workshop, grinding power plant, steel plant, cement plant, carbon foundry and other industries
Filter media air particles, smoke pollution, ultra-fine dust air, etc.

Working Principle

The dust collector is composed of an ash hopper, an upper box, a middle box, a lower box, etc. The upper, middle and lower boxes are of sub-chamber structure. When working, the dust-laden gas enters the ash hopper from the air inlet duct, the coarse dust particles fall directly into the bottom of the ash hopper, and the fine dust particles enter the middle and lower boxes with the turning of the air flow, and the dust accumulates on the outer surface of the filter bag. The gas enters the upper box to the net s gas collection pipe-exhaust duct, and is exhausted to the atmosphere through the exhaust fan. The cleaning process is to cut off the clean air outlet air duct of the chamber first, so that the cloth bag of the chamber is in a state of no airflow passing through the chamber and the air is stopped to clear the dust). Then open the pulse valve and use compressed air for pulse blowing to clean the dust. The shut-off valve is closed for a sufficient time to ensure that the dust peeled off the filter bag after the injection settles into the ash hopper, and the dust is removed from the surface of the filter bag and attached to the air flow. The phenomenon that collects on the surface of the adjacent filter bag makes the filter bag completely clean, and the programmable controller performs automatic control of the exhaust valve, pulse valve and ash discharge valve.

Advantage

  • Long Bag Offline Pulse Dust Collector advantage

    Baghouse dust collector:
    The use of sub-chamber air-stop pulse jet cleaning technology overcomes the shortcomings of conventional pulse dust collectors and sub-chamber back-flushing dust collectors

    structure

    Thickened sheet:

    Strong cleaning ability
    High dust removal efficiency
    Low emission concentrations

  • Long Bag Offline Pulse Dust Collector advantage

    The mouth of the filter bag adopts an elastic expansion ring, which has good sealing performance and is firm and reliable.

    Stability

    Safe and reliable operation:

    The maintenance and replacement of bags can be carried out in different rooms under the normal operating conditions of the system without stopping the system fan.

  • Long Bag Offline Pulse Dust Collector advantage

    The inlet and outlet air ducts are compactly arranged, and the airflow resistance is small

    Efficiencies

    Long service life:

    The filter bag keel adopts polygonal shape, which reduces the friction between the bag and the keel and prolongs the life of the filter bag

  • Long Bag Offline Pulse Dust Collector advantage

    Dust collectors can be selected according to factors such as dust concentration and different filter materials

    Convenience

    Air tightness design:

    Good sealing performance, excellent inspection Sealing material, coal is used in the production process Oil leak detection, low air leakage rate
