Self-excited wet dust collector

Description

Wet dust collector is commonly known as “demister”. It is a device that makes dust-containing gas and liquid (usually water) in close contact, uses the inertial collision of water droplets and particles or the full mixing of water and dust and other effects to capture particles or make particles larger or remain in a fixed container to achieve the effect of water and dust separation.

Wet dust collector can effectively remove liquid or solid particles with a diameter of 0.1-20 microns from the airflow, and at the same time, it can also remove some gaseous pollutants. It has the advantages of simple structure, small footprint, convenient operation and maintenance, and high purification efficiency. It can handle high-temperature and high-humidity airflow and minimize the possibility of fire and explosion. However, when using wet dust collector, special attention should be paid to equipment and pipeline corrosion and sewage and sludge treatment. The wet dust removal process is also not conducive to the recovery of by-products. If the equipment is installed indoors, it is also necessary to consider the problem that the equipment may freeze in winter. In addition, if the efficiency of removing fine particles is also high, the liquid phase needs to be better dispersed, but the energy consumption increases.

Advantages
1. Since the process of mass transfer and heat transfer occurs simultaneously during the contact between gas and liquid, this type of dust collector has both dust removal and flue gas cooling and absorption of harmful gases.
2. Suitable for handling high temperature, flammable and explosive and harmful gases;
3. Normal operation and high purification efficiency;
4. Can be used for dust and gas where fog and dust gather;
5. Exhaust volume balance;
6. Simple structure, small footprint, low investment;
7. Safe operation, easy operation and maintenance

Scope of application
Washing and purification of various industrial dusts, organic odors, acid and alkali waste gas absorption and purification and other harmful gases, boiler flue gas desulfurization, die-casting machines, central furnaces, incinerators and other flue gases, chemical pharmaceuticals, food processing, metallurgy, casting, carbon materials, mechanical processing, building materials, tablet presses, granulators, mixers, ingredients, mixing, vibration screening and other industries.
