pulse jet baghouse dust collector with chamber cleaning

Pulse Jet Baghouse Dust Collector Overview

Different from the traditional bag filter, the pulse jet baghouse dust collector utilizes high pressure airflow to instantaneously jet backblast the dust adhering to the surface of the filter bag, thus keeping the filter bag clear and prolonging the service life of the equipment.
The structure of this kind of dust collector is sturdy, the main body shell is generally welded with carbon steel plate of 5mm or above, and the inner part is equipped with bag assembly, skeleton, pulse spraying system, ash hopper and ash discharging device. The product specifications are varied and suitable for industrial applications of different sizes.

Features of Pulse Jet Baghouse Dust Collector

• High filtration precision: the surface of the filter bag can effectively capture dust particles with a particle size as small as 0.3 microns, with a filtration efficiency of more than 99.9%.
• Modular design: each filter chamber can be individually cleaned, flexible to adapt to different working conditions.
• Strong adaptability: can handle high load airflow with dust concentration up to 1000g/m³.
• Convenient maintenance: the filter bag is easy to install and replace, and the equipment runs stably and reliably.
• Low emission: the dust concentration of the exhaust gas after purification is generally lower than 30mg/m³, far better than most national emission standards.

Advantages of Pulse Jet Baghouse Dust Collector

• High efficiency dust cleaning ability: the use of pulse jetting + chamber offline dust cleaning mode, blowing thoroughly, does not affect the normal filtration of other filter bags, significantly improve the dust removal efficiency and filter bag life.
• Low energy consumption: intelligent control of pulse valve, moderate blowing intensity, saving compressed air consumption, reduce operating costs.
• Stable system operation: reasonable structure, uniform airflow distribution, effectively avoiding filter bag overload and local wear.
• Simplified maintenance: intelligent control system can monitor the pressure difference and ash cleaning cycle in real time, which is convenient for remote management and fault warning.
• Flexible configuration: a variety of combinations of bag number and bag length (such as 32, 64, 96, 128 bags, bag length 2450mm and 3060mm), to meet the needs of different processing capacity.
• Adapt to harsh environments: cold areas can be added with insulation and heating devices to ensure the normal operation of the equipment in winter.

Principle of Pulse Jet Baghouse Dust Collector

Dust-containing waste gas enters into the dust collector through the air inlet, and firstly encounters the inclined partition to divert the flow, and the coarse particles of dust fall into the dust hopper directly due to inertial settling to form the pre-collection of dust. The remaining fine dust goes up with the airflow and passes through the filter bag supported by metal skeleton. The dust is blocked and attached to the outer surface of the filter bag, and the clean gas after purification enters the clean gas room through the filter bag and is discharged through the air outlet.
When the accumulation of dust on the outer surface of the filter bag reaches a set amount, the differential pressure sensor sends out a signal and the control system starts the pulse valve, releasing the compressed air instantly, which is rapidly sprayed inside the filter bag through the blowing pipe, and the surface of the filter bag is briefly swollen and shakes violently, so that the adhering dust is dislodged to the ash hopper.
The design of off-line dust removal in separate chambers suspends the airflow in the chamber during the dust removal process, avoiding secondary dust raising and improving the overall dust removal effect and equipment stability.

Application Areas of Pulse Jet Baghouse Dust Collector

• Building materials industry: cement plant crushing, clinker cooling, grinding mill, warehouse top dust and other processes of dust management.
• Metallurgical industry: iron and steel plant sintering machine, electric arc furnace, blast furnace outlet and other flue gas dust removal.
• Chemical industry: fertilizers, dyes, chemical reactors and other dust and flue gas purification.
• Mining industry: mining, ore dressing, crushing and screening system dust removal.
• Timber and pharmaceutical industry: saw dust, drug powder transportation and drying system dust removal.
• Energy industry: coal dust preparation, coal-fired boiler flue gas purification and waste heat power generation system.
