It is mainly used in water plants, sewage plants, power plants, papermaking, bleaching and dyeing, chemical industries and other places where chlorine is used and stored in large quantities. It is of great significance to ensure production safety and environmental protection.

[0003] After searching, the Chinese patent application number 202123042684.6 discloses an alkali washing tower for tail gas treatment, including a device bottom plate, a water storage tank is fixedly connected to the top of the device bottom plate, a hood shell is fixedly connected to the top of the water storage tank, a circulating water pump is fixedly installed inside the hood shell, and a first connecting pipe is fixedly connected to the output end of the circulating water pump, and a three-way valve is fixedly connected to the inside of the first connecting pipe. In the utility model, by connecting the power supply of the circulating water pump, the water mixed with the neutralizing agent is pumped out, and the extracted mixed liquid enters the two spray layers respectively, and finally the exhaust gas is neutralized through the spray head, and the liquid after spraying will return to the water storage tank through two circulating downpipes, achieving the effect of recycling the spray water.

[0004] The above patent still has the following deficiencies: (1) It is not convenient to adjust the concentration of the absorbent. Since the absorbent reacts with chlorine during the use of the device, its concentration gradually decreases. If the concentration is too low, the absorbent is not convenient to effectively remove pollutants in the exhaust gas. Although the above patent can add the agent into the water tank through the dosing structure, the amount of agent cannot be accurately added, resulting in reduced purification efficiency due to too low agent concentration or waste of agent due to too high agent concentration, thereby affecting the continuity and stability of exhaust gas purification.

[0005] (2) The spray pipe is prone to clogging. Since the inhaled air contains certain dust and foreign matter, during the purification process, the dust and foreign matter are mixed in the absorption liquid and easily enter the circulating water pump and the spray pipe, affecting their normal use.

[0006] Therefore, a chlorine gas absorption and treatment device is urgently needed to solve the above problems. Utility Model Content

[0037] A drain valve 12 is installed on one side of the bottom end of the casing 1;

[0038] The circulating water pump 10 is installed at the top of one side of the casing 1, and the top of the circulating water pump 10 is connected to the first water pipe 7, the top of the first water pipe 7 is connected to the shunt pipe 6, and one side of the shunt pipe 6 is connected to a plurality of spray pipes 15 extending to the inside of the casing 1; Figure 3 As shown, there are 14 spray pipes 15 in total.

[0039] A top cover 4 is fixed to the top of the housing 1, and one side of the top cover 4 is connected to an air suction pipe 5, and one side of the air suction pipe 5 is connected to a fan 11;

[0040] The impurity removal structure 8 is arranged inside the bottom end of the casing 1 and is used to filter the absorption liquid sucked by the circulating water pump 10;

[0041] The dosing structure 9 is arranged at the bottom end of the casing 1, wherein the dosing structure 9 includes a metering pump 904 installed on one side of the casing 1, a dosing pipe 905 installed on one side of the metering pump 904 and extending into the casing 1, a pH value detector 903 installed on one side of the casing 1, and a stirring assembly arranged at the bottom end of the casing 1.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the stirring assembly includes a stirring motor 901 installed at the bottom of the casing 1 and a stirring blade 902 installed at the bottom of the casing 1 and connected to the output shaft of the stirring motor 901. A rotating seal is provided at the connection between the output shaft of the stirring motor 901 and the casing 1. The input end of the metering pump 904 is electrically connected to the output end of the control system of the machine room through a wire. The pH value detector 903 monitors the pH acidity and alkalinity index of the absorbent, so that the machine room can control the metering pump 904 to extract the agent and inject it into the casing 1 through the dosing pipe 905 according to the change of the absorbent index, control the pH value of the absorbent, and ensure the stable operation of the system. The machine room controls the start of the metering pump 904 according to the structure detected by the pH value detector 903. When the pH value exceeds the upper limit, the metering pump 904 stops adding medicine. When the pH value is lower than the lower limit, the metering pump 904 automatically adds medicine, and the stirring motor 901 is started to drive the stirring blade 902 to stir the absorbent to make the absorbent mixed evenly.

[0043] like Figure 1 , Figure 2 and Figure 4 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the impurity removal structure 8 includes a guide shell 801 fixed at the bottom end of the inner part of the casing 1, a connection cover 802 fixed at the top end of the guide shell 801, a second water pipe 803 installed at the top end of the connection cover 802, a filter screen 804 fixed at the bottom end of the connection cover 802, a fixing frame 805 sleeved on the outside of the filter screen 804 and connected to the guide shell 801, and a drain valve 806 installed at the bottom end of the guide shell 801. A water inlet is provided on the side of the connection cover 802, and the front cross section of the guide shell 801 is a funnel-shaped inclined structure, and the guide shell 801 and the casing 1 are integrated. The absorbent enters from the water inlet and is introduced into the interior of the circulating water pump 10 through the second water pipe 803. At the same time, the filter screen 804 filters the absorbent, causing foreign matter to accumulate inside the filter screen 804. When the foreign matter accumulates too thickly, the foreign matter is easily affected by gravity and settles to the bottom of the guide shell 801. By opening the drain valve 806, the sediment inside the guide shell 801 can be easily discharged.

[0044] A packing layer 14 is fixed inside the casing 1 , and a demister 13 is detachably mounted on the top of the casing 1 .

[0046] By monitoring the pH value of the absorbent through the pH value detector 903, the machine room can easily control the metering pump 904 to extract the agent and inject it into the interior of the casing 1 through the dosing pipe 905 according to the changes in the absorbent index, control the pH value of the absorbent, and ensure the stable operation of the system. The machine room controls the start of the metering pump 904 according to the structure detected by the pH value detector 903. When the pH value exceeds the upper limit, the metering pump 904 stops adding medicine. When the pH value is lower than the lower limit, the metering pump 904 automatically adds medicine and starts the stirring motor 901 to drive the stirring blade 902 to stir the absorbent so that the absorbent is evenly mixed.

[0047] The absorbent is introduced into the interior of the circulating water pump 10 through the second water pipe 803, and at the same time, the filter 804 filters the absorption liquid entering the second water pipe 803, so that foreign matter is placed on the surface of the filter 804. When the foreign matter accumulates too thickly, the foreign matter is easily affected by gravity and settles to the bottom end of the guide shell 801. By opening the drain valve 806, the sediment inside the guide shell 801 can be easily discharged.

[0048] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
