Dust collector is a technical equipment used to remove particulate matter from dusty gases to reduce their emissions into the atmosphere. It is widely used in industrial environments to control air pollution and improve air quality.
A dust collector is a set of equipment that uses a dust hood installed at the site of dust emission to transport dusty gas to the dust removal device through a pipeline gas path. After gas-solid separation, the dust is collected in the dust removal device, and the clean gas is introduced into the main pipe or directly discharged into the atmosphere. Its function is to separate solid small particles from aerosols.
The main functions of a dust collector include:
1. Gas solid separation: Separating dust from dusty gases through different working principles.
2. Purifying the air: removing dust from the air and reducing harm to the environment and human health.
3. Dust collection: Collect the separated dust for easy processing and recycling.
应用
Dust collectors have a wide range of applications in industry:
Industrial applications: Used in industries such as metallurgy, mining, building materials, casting, and chemical engineering for workshop dust purification and the recycling and reuse of dust containing gases. The types of industrial dust collectors include gravity settling dust collectors, inertial dust collectors, electrostatic precipitators, wet dust collectors, filter dust collectors, etc.
Dust collectors can be divided into the following types according to their operating principles:
1. Dry mechanical dust collector: relying on mechanical force to remove dust particles from the airflow, with a simple structure and low cost, but low dust removal efficiency.
2. Wet dust collector: a dust removal device that relies on hydraulic humidification to separate and capture dust particles, with high separation efficiency for coarser and hydrophilic dust.
3. Particle layer dust collector: a device that uses layers of particle materials with different particle sizes as filter media to block and filter dust contained in the air solution.
4. Electrostatic precipitator: uses electrostatic force to separate dust particles from airflow, with a dust removal efficiency of over 99%.
5. Filter dust collector: Separate and capture dust particles by passing the dusty airflow through the filter material, with a dust removal efficiency generally ranging from 90% to 99%.
