Wet Scrubber

As a commonly used waste gas treatment equipment in industrial waste gas, wet scrubber is divided into circulating water wet scrubber, alkali liquid wet scrubber, acid liquid wet scrubber (alias: pickling tower) according to the working principle. According to the material of the tower body, it is divided into FRP wet scrubber, PP wet scrubber and SS wet scrubber. Choose reasonable spray material and spray technology according to the different nature of waste gas.

In fishmeal processing, a large amount of odors are easily generated in the process of cooking, pressing, drying, including crushing and concentration. According to the characteristics of fishmeal odors that are easy to biochemically and easily collect, Feed Machinery proposes a biological spray method, which uses a wet scrubber tower combined with biological fillers. It can effectively control and remove the odor of fish meal.

Light weight, easy to install, transport and manage;
Especially suitable for odor removal of fish meal odor;

Application

It can be applied to the exhaust gas purification treatment of fish meal plants, shrimp shell meal plants, meat and bone meal plants, etc.

At the same time, it is suitable for all kinds of electronic component material manufacturing industry, chemical industry and experimental sites containing chemical substances, iron and steel metal industry, electroplating and metal surface treatment industry, pickling and grinding, and removal of combustion exhaust gas.

It can effectively purify sulfuric acid mist, hydrogen chloride, hydrogen fluoride, chlorine, ammonia and sulfur oxides, nitrogen oxides, carbon oxides and other gases generated in the production process.

Working Principle

The exhaust gas is introduced into the scrubber tower by the air duct, and the dust-laden gas is sprayed and washed with the neutralizing liquid in the scrubber tower. Various acid mists, etc.), this type of waste gas is fully contacted and mixed with the neutralizing liquid water mist and fully neutralized, forming a better gas-liquid two-intersection sum. After spraying, the water mist forms a treatment layer with a larger porous contact surface in the packing layer in the scrubbing tower to further purify the gas. After the water mist passes through the packing layer, it continues to return to the water tank at the bottom of the scrubbing tower for recycling. The waste gas is circulated and absorbed through the packing layer from bottom to top, and the spray liquid is sprayed evenly into the packing layer through the nozzle device in the tower, moves down along the surface of the packing layer, and enters the circulating water tank. Due to the continuous contact between the ascending gas and the descending neutralizing liquid in the packing layer, the concentration of the fluid in the ascending gas flow becomes lower and lower, and finally the discharge requirements are met.
