Description

Wet dust collector

Technical Field

The utility model relates to a chemical industry field, concretely relates to wet dust collector.

Background

A wet dust collector is a device which makes dust-contained gas and liquid (generally water) closely contact, utilizes inertial collision of water drops and particles or utilizes the full mixing action of water and dust and other actions to trap the particles or make the particles enlarge or retain in a fixed container to achieve the effect of separating water from dust. The suction force of the high-pressure centrifugal fan is utilized to press the dust-containing gas into the water tank filled with water with a certain height, and the water bath can absorb a part of dust into the water. After the uniform distribution and the flow division, the gas flows from bottom to top, and the high-pressure spray head sprays water mist from top to bottom to collect the rest dust particles. The filtering efficiency can reach more than 85%.

Compared with a dry dust remover, the traditional wet dust remover also needs to deal with secondary pollution of slurry; and a large amount of water is consumed, which means that in cold regions, the risk of icing is also faced. And by itself tends to clog more easily with sticky smoke.

In order to solve the above problems, we have made a series of improvements.
