Description

Technical Field

[0002] The waste gas spray tower is an important component of the spray method for treating waste gas or recovering raw materials, so it is also called a water scrubber, a washing tower, or a purification tower. According to the type of waste gas and the spray liquid, it can be divided into a water spray tower, an acid spray tower, an alkali spray tower, an oil spray tower, a water film dust collector / wet dust collector; according to the shape, it can also be divided into a vertical scrubber and a horizontal scrubber; according to the material, it can be divided into a PP scrubber, a glass fiber reinforced plastic scrubber, etc.

[0003] At present, when the spray tower is in operation, the waste gas is continuously introduced into the purification tower through the air duct, and the waste gas is fully contacted with the sodium hydroxide absorption liquid for absorption and neutralization reaction. After the acid mist waste gas is purified, it is dehydrated and defogged by the defogger plate and then discharged into the atmosphere by the fan. The spray liquid is sprayed out from the spray hole to spray the entire cross-sectional range of the spray tower. The spray liquid after spraying flows into the bottom space of the spray tower through the filtering effect of the filter plate under the action of gravity, forming a spray liquid circulation system, so that the spray liquid purifies the waste gas discharged from multiple gas distribution pipes. However, during the long-term use of the filter plate in the existing waste gas spray tower equipment, when the dirt accumulates to a certain extent, it is easy to cause blockage, and it is difficult to clean it in time, which greatly reduces the filtration efficiency of the waste gas and the spray liquid, bringing inconvenience to people's use.
