Description

A spray type exhaust gas purification tank

technical field

The utility model relates to the technical field of purification for tail gas discharge, in particular to a spray type purification tank for tail gas discharge.

Background technique

Industrial exhaust gas refers to the general term for all kinds of pollutant gases discharged into the air generated during fuel combustion and production processes in the enterprise factory area. These exhaust gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, lead mercury sulfate, beryllium compounds, soot and productive dust, which will pollute the air when discharged into the atmosphere. These substances enter the human body through the respiratory tract in different ways, some directly cause harm, and some have a cumulative effect, which will seriously endanger human health. Different substances will have different effects.

At present, industrial tail gas is one of the important factors that pollute the environment. Then, when purifying industrial tail gas, it is necessary to use a purification tank. Generally, a spray device is installed in the purification tank, and the spray device is used to enter the purification tank. The industrial tail gas is sprayed with purification liquid, and the filter screen is installed inside the purification tank, and the sprayed purification liquid is filtered and reused. Then, the prior art has the following disadvantages: on the one hand, the filter screen is not detachably fixed In the closed integrated purification tank body, the filter screen is easy to block and fail after being used for a long time, which greatly reduces the filtration efficiency of the spray liquid. On the other hand, the position of the nozzle on the spray device is fixed, resulting in the spray range of the purification liquid being limited. Therefore, it cannot fully contact with the industrial exhaust gas, thereby greatly reducing the purification effect. Therefore, we propose a purification tank for spraying exhaust gas discharge.
