1、 Introduction to wet dust collector technology:
The wet dust collector can effectively remove liquid or solid particles with a diameter of 0.1-20 microns from the gas flow, and can also remove some gaseous pollutants. It has the advantages of simple structure, small floor area, convenient operation and maintenance and high purification efficiency. It can deal with high temperature and high humidity airflow and minimize the possibility of ignition and explosion. However, when using wet dust collector, special attention should be paid to equipment and pipeline corrosion and sewage and sludge treatment. Wet dust removal process is also not conducive to the recovery of by-products. If the equipment is installed outdoors, the problem that the equipment may freeze in winter must also be considered. In addition, if the efficiency of removing fine particles is high, the liquid phase needs to be better dispersed, but the energy consumption increases.
2、 Advantages of wet dust collector:
1. Because mass transfer and heat transfer occur simultaneously in the process of gas and liquid contact, this kind of dust collector has the function of dust removal, flue gas cooling and absorbing harmful gases.
2. Suitable for handling high temperature, flammable, explosive and harmful gases;
3. Normal operation and high purification efficiency;
4. Dust and gas that can be used for fog and dust accumulation;
5. Exhaust metering;
6. Simple structure, small floor area and low investment;
7. Safe operation, convenient operation and maintenance, etc.
3、 Classification of wet dust collector:
According to its structure, it can be divided into the following types:
(1) gravity spray wet deduster, such as washing tower.
(2) Cyclone wet dust collector, such as rotary air water film dust collector and water film dust collector.
(3) Self excited wet dust collector, such as impulse dust collector and water bath dust collector.
(4) Packed wet dust collector, such as packed tower and turbulent ball tower.
(5) foam wet dust catcher, such as foam precipitator, cyclone dust collector and leaking tower.
(6) Venturi wet dust collector, such as venturi dust collector.
(7) Mechanically induced dust collector, such as water wheel dust collector.
4、 Scope of application:
Washing and purification of harmful gases such as industrial dust, organic odor, acid-base waste gas absorption and purification, boiler flue gas desulfurization, flue gas from die casting machine, central furnace and incinerator, chemical pharmacy, food processing, metallurgy, casting, carbon materials, machining, building materials, tablet press, granulator, mixer, batching, mixing, vibrating screen and other industries.
