★ What are the common types of vacuum cleaners?

Bag filter is a dry dust filter. Suitable for collecting fine, dry and non-fibrous dust.

The filter bag is made of woven filter cloth or non-woven felt, and uses the filtering effect of fiber fabric to filter dusty gas. When the dusty gas enters the bag filter, the dust with large particles and heavy proportion settles down and falls into the ash hopper. When the gas containing fine dust passes through the filter material, the dust is trapped and the gas is purified.

2, wet dust collector

Wet dust collector, commonly known as "demister", is a device that makes dusty gas closely contact with liquid (usually water), and uses the inertial collision between water droplets and particles or the full mixing of water and dust to capture particles or make particles grow or stay in a fixed container, so as to achieve the separation effect of water and dust.

3. Electric vacuum cleaner

Electrostatic precipitator, also known as electrostatic precipitator, is a dust removal device that charges dust particles in gas by corona discharge and separates them from airflow by electrostatic field. According to the different forms of collecting electrodes, electrostatic precipitators can be divided into plate type and tube type.

Electrostatic precipitator is composed of corona electrode, dust collecting electrode, air distribution device, vibrating dust cleaning device, shell and power supply equipment.

4, industrial dust collector

Industrial dust collector, also known as industrial vacuum cleaner, is used for industrial purposes to collect and absorb waste media particles, dust and smoke, oil and water generated in the process of production, operation and transportation.

Industrial vacuum cleaners use AC power supply with high power, which is generally divided into two types: mobile and fixed. The multiphase mixture involved in industrial dust removal is called gas suspension system or aerosol. The fine particles dispersed in it are called dust particles or particles, and the accumulation state of dust particles is called powder.

5, filter dust collector

Filter dust collector is a kind of high-efficiency dust removal equipment, which makes dusty gas pass through a certain filter material and separates solid dust from the gas. There are two main types of filter dusters.

One is a bag filter with fiber braid as filter medium; The other is granular layer dust collector, which uses sand, gravel, coke and other particles as filter media.
