The interior of the exhaust gas treatment device 1 is provided with a liquid storage layer 11, a packing layer 12, a spray layer 13 and a demisting layer 14 in sequence from bottom to top. The packing layer 12 and the spray layer 13 can be arranged in multiple layers. The liquid storage layer 11 is used to store the spray liquid and transport the spray liquid to the spray layer 13; the packing layer 12 is used to increase the contact area between the exhaust gas and the spray liquid, prolong the contact time between the exhaust gas and the spray liquid, so that the exhaust gas and the spray liquid fully react, and improve the purification efficiency; the spray layer 13 draws the spray liquid from the liquid storage layer 11, evenly sprays the spray liquid, and the exhaust gas reacts with the spray liquid; the demisting layer 14 is located at the top of the exhaust gas treatment device 1, and is used to demist the treated exhaust gas, and the purified gas after demisting is discharged from the top of the exhaust gas treatment device 1.

The liquid storage layer 11 includes a liquid storage tank 111, a valve 112, a dosing box 113, a cleaning device 114, a water pump 115, an air inlet 116 and a water storage inspection port 117. The bottom of the liquid storage tank 111 is funnel-shaped, and the valve 112 is opened at the bottom. The bottom of the liquid storage tank 111 is connected to the dosing box 113, and the valve 112 is immersed in the dosing box 113. The dosing box 113 adjusts the concentration of the spray agent in the liquid storage tank 111 and controls the dosing amount through a metering pump. The liquid storage tank 111 can be connected to the sewage pool (not shown) outside the waste gas treatment device 1 through the valve 112 connecting pipe; the cleaning device 114 passes through the tower body of the waste gas treatment device 1, and the nozzle is aimed at the center of the liquid storage tank 111, which is used to clean the liquid storage tank 111. The bottom of the liquid storage tank 111 can be connected to the external sewage pool through a pipe. When the cleaning device 114 cleans, pollutants and sewage flow into the sewage pool along the tank wall of the liquid storage tank 111. The water pump 115 is located outside the waste gas treatment device 1 and is connected to the liquid storage tank 111 through a pipe. The water pump 115 is used to circulate the spray agent. The water pump 115 extracts the spray liquid in the liquid storage tank 111 to the spray layer 13, and the spray liquid sprayed by the spray layer 13 falls back to the liquid storage tank 111. The spray agent reacts with the waste gas to produce a neutralization reaction, and the concentration of the spray liquid decreases. The bottom of the liquid storage tank 111 is connected to the dosing box 113 to add medicine to increase the concentration of the spray liquid, and the amount of medicine added is controlled by a metering pump. The liquid storage layer 11 is also provided with an air inlet 116, which is located between the liquid storage tank 111 and the packing layer 12. The waste gas to be treated enters the interior of the waste gas treatment device 1 from the air inlet 116. The air inlet 116 tilts into the interior of the waste gas treatment device 1 until the center position. The pipe mouth of the air inlet 116 is bent and aligned with the bottom of the tower, so that the waste gas is evenly distributed inside the waste gas treatment device 1; the water storage inspection port 117 is opened on the liquid storage layer 11, and the water storage inspection port 117 is located above the liquid storage tank 111.

The demisting device 141 is installed on the top of the exhaust gas treatment device 1 and is used to demist the treated exhaust gas. The exhaust port 142 is located above the demisting device 141 and at the top of the exhaust gas treatment device 1. The exhaust port 142 is used to discharge the treated harmless gas.

The working principle of the waste gas treatment device 1 described in the utility model is as follows: when treating waste gas, the waste gas enters the waste gas treatment device 1 from the air inlet 114, and the waste gas passes through the packing layer 12, the spray layer 13 and the demisting layer 14 in sequence upward, and is discharged from the exhaust port 142; the spray agent is pumped from the liquid storage tank 111 into the water pipe 131 through the water pump 113, enters the spray layer 13, and is sprayed downward from the spray head 133; the packing layer 12 performs gas-liquid exchange, and the contact area of the waste gas with the spray liquid increases when passing through the packing layer 12, the movement speed slows down, and the contact time with the spray liquid is prolonged, the packing layer 12 washes out the fine particles in the waste gas, and absorbs part of the gas dissolved in water, and the spray liquid after the reaction falls back to the liquid storage tank 111; the demisting layer 14 demists the treated waste gas, and the purified gas after demisting is discharged from the exhaust port 142. After the spray liquid reacts with the exhaust gas for a period of time, the concentration decreases. The bottom of the liquid storage tank 111 is connected to a dosing box, and the spray liquid is added to the liquid storage tank 111 through a metering pump.

When the waste gas treatment device 1 is maintained, the bottom end of the liquid storage tank 111 is connected to the sewage tank, and the cleaning device 112 cleans the liquid storage tank 111. Pollutants and sewage flow into the sewage tank from the bottom end of the liquid storage tank 111. Maintenance personnel can enter the liquid storage tank 111 from the water storage inspection port 115 for cleaning; maintenance personnel enter the packing layer 12 from the packing inspection port 123, lay a support plate for easy work on the workbench 122, remove the support plate during non-maintenance period, and rinse the packing 121 on the workbench 122. Pollutants and sewage flow along the workbench 122 to the packing inspection port 134 or fall into the liquid storage tank. The packing layer 12 has a loose structure, and maintenance personnel cannot stand on the packing layer 120 to work. Since the water pipe 131 passes through the spray inspection port 134 and is placed on the mounting platform 132, the water pipe 131 is removed and pulled out from the spray inspection port 134. The maintenance personnel do not need to enter the exhaust gas treatment device 1, and the time-consuming and labor-intensive measures of setting up scaffolding and other high-altitude facilities inside the exhaust gas treatment device to maintain the water pipe 131 and the spray head 133 are avoided.

In summary, the utility model is convenient for later maintenance and prolongs the service life of the exhaust gas treatment device; at the same time, it increases the contact area between the exhaust gas and the spray liquid, prolongs the contact time, and improves the efficiency of exhaust gas purification.
