DMC Pulse Bag Dust Collector
Introduction
The DMC Pulse Bag Dust Collector is a high-efficiency industrial dust collection and air purification system that uses pulse-jet cleaning technology to maintain continuous filtration performance across demanding industrial environments. Also known as a pulse jet baghouse or pulse jet fabric filter, the system operates by injecting high-pressure compressed air into the top of filter bags at timed intervals, dislodging accumulated dust particles and restoring filter bag permeability without interrupting operation.
The DMC Pulse Bag Dust Collector is suitable for dust removal, air purification, and material recovery from non-fibrous industrial dust across a wide range of processing conditions. It delivers high dust collection efficiency, long filter bag service life, low air leakage rates, stable operation, and strong economic performance across extended continuous production runs.
Application Fields and Range
Application Fields
The DMC Pulse Bag Dust Collector is widely used across cement, electronics, chemicals, food processing, metallurgy, casting, carbon materials, machinery processing, wood, and building materials industries.
Application Range
Specific applications include dust removal from calcium carbide furnaces, electric furnace dust collection in iron alloy plants, fuel gas purification in iron and steel plants, dust removal from coal-fired boilers and power plant boilers, dust collection from garbage incinerators, fuel gas purification in aluminum plants, tail gas dust collection in carbon black plants, and fuel gas purification in smelting operations.
Key Technical Parameters:
Filter area: 24 to 84 m²
Resistance: 1200 Pa or less
Inlet dust concentration: below 200 Nm³/min
Filtration speed: 1.2 to 2.0 m/min
Filter bag selection varies according to dust particle size and specific processing conditions.
Structure and Working Principle
The DMC Pulse Bag Dust Collector consists of the following primary components: clean air chamber, electromagnetic pulse valve, cylinder, air chamber with sealed access door, enclosure, clean gas outlet, outlet pipes, chimney, air volume control valve, induced draft fan, lower housing, closed air feeder, dust chamber, support legs, screw conveyor, pulse controller, storage tanks, reflux valve, air compressor, pressure valve, compressed air system, inlet pipe, filter bags, air bag, and pulse valve assembly.
In operation, the system uses compressed air as the driving force for dust cleaning. The pulse injection mechanism releases compressed air in timed bursts, inducing a secondary high-speed air pulse into the filter bags. This causes the bags to expand rapidly, shaking off accumulated dust and restoring filtration efficiency without taking the system offline.
The DMC series is available in the following filter bag configurations: 24, 36, 48, 60, 72, 84, 96, 108, 112, and up to 180 bags, allowing the system to be scaled to match specific processing volumes and dust loads.
Sequence of Operation
1. Dust-laden air enters the dust collector through the inlet duct.
2. Air passes through the filter media while dust particles are retained on the outer surface of the filter bags.
3. A signal from the pulse controller timer actuates the opening of the normally closed solenoid valve at timed intervals.
4. A momentary pulse of compressed air flows from the air header through the purge pipe and into each filter bag in sequence. This pressure reversal momentarily takes each row of bags offline for cleaning.
5. Dislodged dust particles fall into the filter hopper or collection bin below.
6. Cleaned air exits through the clean air plenum and exhaust outlet, completing the filtration cycle.
Features and Advantages
1. High dust collection efficiency with low energy consumption, maintaining effective filtration performance across continuous industrial production operations.
2. Long filter bag service life achieved through advanced pulse-jet cleaning technology that removes accumulated dust without mechanical stress on the filter media.
3. Strong cleaning capability with low air leakage rate, ensuring consistently clean exhaust air output that meets environmental protection standards.
4. Small footprint relative to processing capacity, reducing space requirements in industrial facilities without compromising filtration performance.
5. Stable and reliable operation with low maintenance requirements, delivering strong economic performance across extended production runs.
6. Available in multiple filter bag configurations from 24 to 180 bags, allowing flexible scaling to match specific dust loads and processing volumes.
