Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts belong to the protection scope of the present application. It can be understood that the accompanying drawings are only for reference and illustration, and are not used to limit the present application. The connection relationships shown in the drawings are only for clear description and do not limit the connection methods.

[0035] Specifically, as Figure 1As shown in the figure, an exhaust gas treatment device for AOP water treatment disinfection is provided in an embodiment of the present application. Here, AOP is the advanced oxidation processes. The treatment device is mainly provided with a reaction tank gas-liquid separation valve 300, an ozone destructor 200, and a water seal pipe 100. Among them, the reaction tank gas-liquid separation valve 300 mainly discharges the exhaust gas generated by the reaction of ozone and water. During the discharge process, the gas first enters the water seal pipe 100. A water seal device 120 is provided on the water seal pipe 100, and the water seal device 120 can perform water seal treatment on the exhaust gas. Specifically, the treatment process is as follows:

[0036] The water seal pipe 100 is specifically a pipe body 110. A flow cavity 111 is opened in the pipe body 110. An intake pipe 130 and an outlet pipe 140 are also provided on the pipe body 110. Both the intake pipe 130 and the outlet pipe 140 communicate with the flow cavity 111. In an embodiment of the present application, both the intake pipe 130 and the outlet pipe 140 are provided on one side of the water seal pipe 100. A water seal device 120 is provided at a position in the flow cavity 111 away from the intake pipe 130 and the outlet pipe 140. The water seal device 120 can seal one end of the flow cavity through condensed water. Specifically, the water seal device 120 includes a fixing member 121 and a floating member 122. The fixing member 121 is located inside the pipe body 110 and is integrally connected to the pipe body 110. A through hole 1211 is provided on the fixing member 121. The through hole 1211 penetrates the pipe body 110 and communicates with the flow cavity 111. When the gas is in the flow cavity 111, the gas will flow out of the flow cavity 111 through the through hole 1211. To avoid this situation, a floating member 122 is sleeved on the fixing member 121. A fixing cavity 1222 is opened at a position on the floating member 122 corresponding to the fixing member 121. An opening 1223 is opened at a position on the fixing cavity 1222 corresponding to the fixing member 121. The fixing member 121 enters the fixing cavity 1222 through the opening 1223, realizing the sleeving of the floating member 122 on the fixing member 121. Among them, the density of the floating member 122 is less than the density of water.

[0037] Regarding the fixing member 121, in an embodiment of the present application, a water seal device 120 is also provided. In the water seal device 120, the fixing member 121 is fixedly connected through a bushing at the bottom of the pipe body 110.

[0038] Setting the above structure can make it so that when the gas enters the water seal pipe 100, when the gas contacts the inner wall of the pipe body 110, the gas temperature decreases, and some substances (i.e., water vapor) in the gas will condense into water droplets and hang on the pipe body 110. And in an embodiment of the present application, as Figures 4 - 6As shown, the water seal tube 100 is vertically arranged, and the water seal device 120 is arranged at the bottom position. When water droplets flow into the water seal device 120 at the bottom of the tube body 110 under the action of their own gravity, since the density of the float 122 in the water seal device 120 is less than the density of the water, when the water at the bottom position accumulates, the float 122 will be lifted, wherein the through hole 1211 on the fixing member 121 is blocked by the float 122, and the float 122 will be partially located under the water surface due to its own gravity, so that the through hole 1211 cannot be connected with the flow cavity 111, thereby achieving the effect of water seal.

[0039] In the embodiment of the present application, when more and more water accumulates in the tube body 110, the water needs to be discharged. At this time, when the water depth in the tube is greater than the height of the fixing member 121, the water will be discharged from the through hole 1211 through the communicating vessel principle.

[0040] At the same time, a limiting member 1221 is also provided on the tube body 110. Two limiting members 1221 are provided. The two limiting members 1221 are arranged opposite to each other. Figure 3 As shown, when the water pressure in the circulation chamber 111 increases, it will drive the float 122 to rise. When the float 122 rises to a certain height, the top of the float 122 will contact the limiting member 1221, so that the float 122 cannot continue to rise. At this time, the part of the float 122 facing the water surface is still in the water, so as to maintain the water seal state. At the same time, the setting of the limiting member 1221 can make the float 122 abut against the inner wall of the circulation chamber 111. When the water level rises, the opening 1223 of the float 122 will be separated from the corresponding position of the fixing member 121, so as to prevent the float 122 from being unable to be mounted on the fixing member 121.

[0041] In the embodiment of the present application, an ozone destroyer 200 is also provided. Figure 7 As shown, the ozone destroyer 200 can destroy ozone to achieve the purpose of protecting the environment. Specifically, the ozone destroyer 200 mainly includes a shell 210 and a heat-insulating cotton 220. An inner cavity 221 is opened in the heat-insulating cotton 220. Ozone can be destroyed through the inner cavity 221. The destruction process mainly destroys the ozone gas through the electric heating element 240 and decomposes it into oxygen. In order to improve the decomposition efficiency, a heating rod 241 is arranged on the electric heating element 240. The heating rod 241 is arranged as a whole in the inner cavity 221. When the ozone gas passes through the inner cavity 221, the ozone can be decomposed at high temperature to prevent the ozone gas from causing harm to the atmosphere.

[0042] In the embodiment of the present application, a temperature sensor 230 and a temperature controller are also included, wherein the temperature sensor 230 is located in the inner cavity 221 , and the temperature controller is arranged on the ozone destroyer 200 .

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
