Baghouse Dust Collector

Efficient Pulse-Jet Dust Filtration System

The baghouse dust collector, also known as a pulse-jet bag filter, is an advanced type of pulse jet dust collector designed to overcome the limitations of traditional bag filters, such as insufficient ash cleaning strength and uneven airflow distribution. It uses compressed air pulses to effectively remove dust particles adhered to the filter media, enhancing overall dust collection efficiency.

Baghouse Dust Collector

Controlling the flue gas filtration speed is critical during operation. Typically, filter speeds range from 0.5 to 2 meters per minute. For particles larger than 0.1 micrometers, the dust removal efficiency can exceed 99%, while the system operates at a pressure loss between 980 and 1470 Pascals.

The PPC type baghouse dust collector finds widespread application in industries such as building materials, cement, metallurgy, machinery, chemical processing, and refractory manufacturing. It is especially prevalent in cement plants for dust collection systems associated with crushers, packaging machines, warehouse tops, clinker coolers, and various cement grinding machines. Alongside baghouse dust collectors, electrostatic precipitators and cyclone dust collectors are also common in cement plant dust control systems.

Advantages of Baghouse Dust Collector

The baghouse dust collector consists of key components including an ash bucket, upper, middle, and lower box bodies divided into chambers. During operation, dusty gas enters through the air inlet and larger dust particles settle directly into the ash bucket by gravity. Finer dust rises with the airflow into the middle and lower boxes, where dust accumulates on the outer surfaces of filter bags. The filtered clean air then passes into the upper box and is discharged through the clean gas collector pipe and exhaust duct by an exhaust fan.

Dust Removal Process

Ash cleaning is achieved by temporarily stopping airflow through specific filter chambers. Compressed air pulses are released through pulse valves to dislodge dust from the filter bags. Adequate closing time of the airtight valves ensures ash settles into the hopper without contaminating adjacent filters. This process is fully controlled by a programmable controller that manages exhaust valves, pulse valves, and discharge valves automatically.

Dust-laden gas enters through the air inlet, where large particles separate by inertia and gravity, falling into the dust hopper. Remaining gases pass through the filter bags where dust particles are trapped on the surface, allowing purified air to exit through the upper chamber.

Key Features

Excellent Sealing: Advanced sealing technologies reduce air leakage to below 2%, prolonging filter bag life and improving dust removal.
Wide Applicability: Utilizes new high-quality filter materials and reliable flue gas temperature tracking for use in diverse industrial gases.
High Efficiency: Pulse-jet bag filters achieve dust removal rates above 99.9%, maintaining dust emissions below 30 mg/Nm³ and handling dust concentrations up to 100 g/Nm³.
Stable Operation & Easy Maintenance: Key components are highly automated and reliable. Pulse backflushing with high-temperature flue gas prevents dew formation and bag clogging.
Advanced Design: The gas box structure minimizes local resistance and simplifies filter bag installation.
Simple Selection Guide

Systems can be tailored to site-specific conditions with either online or offline ash cleaning to address different cleaning needs efficiently. Depending on process and pressure requirements, operators may choose high or low-pressure pulse cleaning modes. The typical service life of pulse valves exceeds five years, while filter bags last over two years.

Low operating costs are maintained through efficient compressed air usage and gas injection drainage, ensuring optimal dust removal pressure at the filter bag’s base.
