What Is an Industrial Dust Collector?

Jul. 13, 2021

Industrial dust collector is a kind of air pollution control equipment used in factories, workshops, warehouses and other industrial or commercial places to meet the safety requirements of the environment and workplaces. An effective dust collection system controls, reduces and removes potentially harmful particles and smoke in the gas or air and the surrounding environment during the production process. This equipment is specially used to purify and filter harmful dust and fine particulate pollutants released into the working environment or the atmosphere to maintain and improve air quality.

The types of pollutants vary from industry to industry. Therefore, the industrial dust collector is designed for the extraction method required by each industry. The working principle of the dust collection system is generally to suck dust and particles in the air through a filter. The filter first captures and separates the substances, and then discharges the purified air back to the workplace or the environment. The goal of each design application is essentially the same-filter, separate and capture dust and particulate matter, and release purified air.

The basic components of the dust collector include a blower, a dust filter, a dust collector cleaning system, a dust collector and a dust removal system. Five common types of dust removal equipment are fabric filter baghouses, inertial separator (such as mechanical cyclone), drum collector, wet scrubber and electrostatic precipitator.

Bag filters come in various designs and are the most commonly used system due to their 99% efficiency.

Dust collection is vital to many industrial sectors such as woodworking, agriculture, food processing, pharmaceuticals, recycling, cement and rock products, metal manufacturing, mining and chemical processing. Dust collectors called filter receivers are an important part of the processing system, used in many thermal and downsizing applications and as receivers for pneumatic conveying.

Pulse jet dust collector is another bag type dust collector system, in order to meet the needs of industrial applications, a variety of designs are used. The bag cleaning system is cleaned by a rapid, high-pressure air jet, sending shock waves or impacts through the bag, crushing and discharging the dust cake for processing. The rapid pulsation of air allows the fan to run continuously, so the system is generally not divided. Pulse jet models are the most common type of industrial dust collector because of their ability to be easily customized, their ability to handle a wide range of temperatures and pressures, and their high collection efficiency.

The cyclone dust collector is an inertial separator that separates dust from the airflow by centrifugal force. By generating a cyclone in the cyclone collection chamber, the air is purified. An intense circular airflow resembling a vortex pushes dust particles to the wall of the cyclone separator, and then slides to the bottom of the hopper for collection. The cyclone system can remove heavier and larger particles mixed with fine dust. They are often used as pre-cleaners before the baghouse.
