The advantages of wet dust remover in the industry

The cost of the wet dust collector is relatively low. But for chemical, spray paint, spray glaze, pigments and other industries with water, sticky and pungent odor of dust is an ideal way of dust removal. Because it can not only remove dust, but also use water to remove a part of peculiar smell. If it is harmful gas (such as a small amount of sulfur dioxide, hydrochloric acid fog... Absorbents can be absorbed in the washing liquid.

Shortcomings:

1, there are washing sludge to solve the problem of sludge and sewage.

2, the equipment needs to choose the corrosion resistant material.

3, the power consumption is larger.

4, northern or cold areas need to consider equipment antifreeze.

There are many wet dust remover used in engineering. In general, it can be divided into two types: low energy and high energy. The pressure loss of the low energy wet dust collector is 0.2 - 1.5kPa, including the spray tower and the cyclone scrubber. The water consumption (liquid and gas ratio) is 0.5 to 3 litres per cubic meter under the general operating conditions. The purification efficiency of the particles above 10 microns can reach 90% to 95%. The pressure loss of the high energy wet dust collector is 2.5 to 9.0kPa, and the purification efficiency is 2.5. The rate can reach over 99.5%, such as Venturi scrubber.

Wet dust remover can effectively remove liquid or solid particles with diameters of 0.1 to 20 microns from the airstream, and also remove some gaseous pollutants. It has the advantages of simple structure, small area, convenient operation and maintenance and high purification efficiency. It can handle high temperature and high humidity airflow, and reduce the possibility of ignition and explosion to low. But when using wet dust remover, 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 indoors, it is also necessary to consider the problem of equipment freezing in winter.
