DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] A chemical production waste gas treatment device for a buffer tank, such as Figure 1-Figure 4As shown, it includes a buffer tank 1; a buffer mechanism 2 is arranged in the buffer tank 1, and a reaction mechanism 3 includes an air inlet pipe 201, the air inlet pipe 201 is fixedly connected to the bottom end of the buffer tank 1, the end of the air inlet pipe 201 is a U-shaped pipe structure, the end of the air inlet pipe 201 is fixedly connected to a buffer pipe 202, the bottom end of the buffer tank 1 is fixedly connected to a partition 203, the partition 203 is an annular structure, the top of the partition 203 is fixedly connected to a baffle 204, the end of the buffer pipe 202 and the baffle 204 are located corresponding to each other, the buffer mechanism 2 can buffer the gas entering the buffer tank 1, thereby reducing the flow rate of the gas after entering the interior, prolonging the time between the exhaust gas and the reaction material, and thus improving the exhaust gas treatment effect, the baffle 204 structure will buffer The interior of the buffer tank 1 is divided into four independent exhaust gas treatment areas. The end of the buffer pipe 202 corresponds to the baffle 204. When the exhaust gas in the buffer pipe 202 enters the buffer tank 1 at different gas flow rates, the exhaust gas will enter different exhaust gas treatment areas, so as to keep the exhaust gas treatment time similar under different exhaust gas flow rates, thereby stabilizing the exhaust gas treatment effect. The bottom of the buffer tank 1 is filled with a buffer solution, and the bottom of the baffle 204 is immersed in the buffer solution. A liquid exchange port 205 is provided at the bottom of the buffer tank 1. The buffer solution can pre-treat the exhaust gas. At the same time, the liquid can buffer the exhaust gas when the exhaust gas impacts, thereby increasing the resistance of the exhaust gas entering the buffer tank 1, and further achieving the buffering effect of the exhaust gas. The flow trajectory in the body is related to the flow rate of the exhaust gas, so that the exhaust gas can be guided to different reaction treatment areas at different flow rates. When the exhaust gas flow rate is low, the exhaust gas flows out of the buffer tube 202 and is directly floated by the resistance of the buffer solution, thereby guiding the exhaust gas to one side of the baffle 204, while the exhaust gas treatment area on the other side of the baffle 204 is in an idle standby state. When the exhaust gas flow rate is high, the exhaust gas forms a flow channel inside the buffer solution and impacts the bottom end of the baffle 204, so that the exhaust gas can flow directly to both sides of the baffle 204, thereby increasing the exhaust gas treatment space. By increasing the treatment space, the flow rate of the exhaust gas inside the buffer tank 1 can be reduced, thereby achieving the effect of improving the exhaust gas treatment. The buffer tube 202 An adjusting block 206 is fixedly connected to the outer end, and an adjusting rod 207 is rotatably connected to one end of the adjusting block 206. The adjusting block 206 structure can conveniently adjust the angle of the buffer tube 202, and the buffering effect of the exhaust gas can be adjusted by adjusting the angle of the buffer tube 202. A screw 208 is rotatably connected to the bottom end of the buffer tank 1, and a driving block 209 is meshedly connected to the screw 208. The end of the adjusting rod 207 is rotatably connected to the side of the driving block 209, and the bottom end of the screw 208 is set through the buffer tank 1. A driving handle 210 is fixedly connected to the bottom end of the screw 208. The screw 208 structure can cooperate with the driving block 209, thereby driving the adjusting block 206 and the buffer tube 202 to be adjusted synchronously.

[0027] Example 2

[0028] like Figure 1-Figure 3 As shown, a reaction mechanism 3 is provided inside the buffer tank 1, and the reaction mechanism 3 includes a bracket 301, the bracket 301 is fixedly connected between the baffles 204, a guide plate 302 is fixedly connected in the middle of the bracket 301, and a storage block 303 is movably connected to the bracket 301. The reaction mechanism 3 can process the exhaust gas, and the bracket 301 can support the storage block 303. At the same time, the storage block 303 is a porous structure, and the reaction position is filled and stored inside. When the exhaust gas passes through and passes through the storage block 303, the reaction material inside the storage block 303 contacts and reacts with the exhaust gas to achieve the treatment of the exhaust gas. The guide plate 302 structure can guide the flow trajectory of the exhaust gas, so that the exhaust gas inside the buffer tank 1 An N-shaped flow is carried out, thereby further extending the treatment time of the exhaust gas. A maintenance plate 304 is rotatably connected to the guide plate 302, and a maintenance door 305 is rotatably connected to the outer side of the buffer tank 1. The maintenance door 305 and the maintenance plate 304 correspond to each other. The outer sides of the maintenance plate 304 and the maintenance door 305 are surrounded by sealing gaskets. The maintenance plate 304 and the maintenance door 305 structure can facilitate the staff to maintain the inside of the buffer tank 1 and replace the storage block 303, so as to maintain the treatment effect of the exhaust gas. An exhaust pipe 306 is fixedly connected to the middle of the buffer tank 1. The top of the exhaust pipe 306 is arranged through the buffer tank 1, and an exhaust port 307 is opened at the bottom end of the side of the exhaust pipe 306.

[0029] When the waste gas treatment device for a buffer tank of the utility model is in use, the waste gas enters the buffer tank 1 from the air inlet pipe 201 and contacts the buffer solution at the bottom of the buffer tank 1. The buffer solution buffers the buffer solution through the resistance of the liquid. When the waste gas flow rate is low, it directly floats to one side of the baffle 204. When the waste gas flow rate is high, it impacts the bottom of the baffle 204 and flows to both sides of the baffle 204. When the waste gas flows into the buffer tank 1, the waste gas flows along the flow channel inside the buffer tank 1 and contacts the waste gas storage block 30. 3, and then contacts with the reaction material inside the storage block 303, and processes the waste gas. After multi-stage processing, the waste gas flows through the exhaust port 307 and is discharged from the exhaust pipe 306 to the subsequent equipment. When it is necessary to adjust the angle of the buffer tube 202, it is only necessary to rotate the driving handle 210, and the screw 208 rotates accordingly and drives the adjusting block 206 to move through the meshing driving block 209, so that the angle of the buffer tube 202 can be adjusted. By adjusting the buffer tube 202, the waste gas with different flow rates can be diverted and buffered.
