The MDC Pulse Bag Filter

Introduction：The pulse bag dust collector, with its core technology of “separate chamber airflow-stop + pulsed injection,” achieves near-zero emissions through intelligent control and innovative materials. Its modular design adapts to high-dust, high-temperature, and high-corrosion environments across multiple industries, making it a key piece of equipment for cost reduction, efficiency improvement, and environmental compliance in the green industrial transformation. The equipment consists of a hopper (coarse particle settling area), a middle housing (filter bag filtration area), an upper housing (clean air chamber), and a pulse jet system. The filter bag material can be selected according to the operating conditions.
Working principle：Dust-laden air enters the middle and lower housings from the dust collector's air inlet. It is filtered through the filter bags, separating dust and air. Dust is adsorbed on the filter bag surfaces, and clean air passes through the bags and is discharged through the air outlet. Over time, as dust accumulates on the filter bag surfaces, the pulse jet valves are triggered and opened sequentially according to the pulse jet instrument's program. Compressed air in the air bag is instantly ejected from each hole in the jet pipe, through a venturi, and into the corresponding filter bag. Dust adsorbed on the filter bag surfaces is then dislodged and falls into the hopper, where it is discharged through the ash discharge valve or directly into the hopper.
