Industrial Dust Collection Equipment

Definition

An industrial dust collector, also known as industrial dust collection equipment, is a device used to separate industrial dust from flue gas. The performance of a dust collector is expressed by the gas volume it can handle, the pressure drop (resistance loss) as gas passes through the collector, and the dust collection efficiency. Additionally, the price, operating and maintenance costs, service life, and ease of operation and management are also important factors in evaluating the performance of a dust collector.

Applications

Industrial dust collection equipment is widely used for workshop air purification and the recovery and reuse of dust-laden gas in industries such as metallurgy, mining, building materials, foundry, chemicals, tobacco, electronics, asphalt, cement, machinery, grain, machining, boilers, flour production, and others.

Working Principles

1. Biological Nano-Membrane Dust Suppression Technology

The biological nano-membrane is a double-ion layer membrane with an interlayer spacing at the nanometer scale. It maximizes the extensibility of water molecules and possesses strong electrostatic adsorption properties. When sprayed onto the surface of materials, it attracts and agglomerates small dust particles, causing them to form larger dust aggregates. As the aggregate weight increases, they settle naturally. This technology achieves a dust removal efficiency of over 99%, with an average operating cost of 0.05–0.5 RMB per ton.

2. Cloud Fog Dust Suppression Technology

This technology uses high-pressure ion atomization and ultrasonic atomization to generate ultra-fine dry fog with particle sizes ranging from 1 μm to 100 μm. The ultra-fine dry fog particles are dense and fully increase the contact area with dust particles. Water fog particles collide and coalesce with dust particles, forming agglomerates that continuously grow larger and heavier until they naturally settle, achieving dust elimination. Of the dry fog particles generated, 30%–40% have a particle size below 2.5 μm, making this technology particularly effective for controlling fine particulate air pollution.

3. Wet Dust Collection

Wet dust collection technology uses pressure drop to absorb air containing attached dust. Dust removal is achieved through the combined action of centrifugal force and the mixing of water with dust-laden gas. Key design features such as specialized impellers provide extremely high dust collection efficiency.
