Description

Technical Field

[0001] The utility model relates to the technical field of fine chemical engineering, in particular to a reaction kettle with a tail gas absorption and treatment component. Background Art

[0002] A reaction kettle refers to a device commonly used in the production of products in the field of fine chemical engineering. A reaction kettle is a container for physical or chemical reactions. After adding a variety of raw materials into the kettle body, a series of heating, evaporation, cooling, and mixing functions at low and high speeds can be carried out on the raw materials according to the process requirements. It is widely used in fields such as petroleum, chemical industry, and rubber. Since certain waste gases may be generated during the reaction in the reaction kettle, causing air pollution, a reaction kettle with a tail gas absorption and treatment component is required.

[0003] Currently, the reaction kettle with a tail gas absorption and treatment component uses a filter screen to first filter impurities in the gas, and then passes the tail gas into a purification box for purification. However, on the one hand, the filter screen is easily blocked, and the filtering effect on small particles in the gas is not good. Therefore, it may affect the treatment effect of waste gases. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a reaction kettle with a tail gas absorption and treatment component that can overcome the above problems or at least partially solve the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A reaction kettle with a tail gas absorption and treatment component, including: a reaction kettle body, further including: a sealing cover, threadedly connected to the reaction kettle body; a treatment box; a second rotating shaft, rotatably arranged in the treatment box; a plurality of mesh plates, fixedly arranged in a circle on the second rotating shaft; a second motor, fixedly arranged on one side of the treatment box, and the output end of the second motor is fixedly connected to the second rotating shaft; an air inlet pipe, arranged on the sealing cover, and the air inlet pipe is communicated with the lower end of the treatment box; an exhaust pipe, arranged on the upper side of the treatment box; a purification box, fixedly arranged on one side of the treatment box, and the input end of the purification box is communicated with the exhaust pipe.

[0007] Preferably, a threaded cover is threadedly connected to the sealing cover. A first rotating shaft is rotatably arranged in the reaction kettle body. A first motor is fixedly connected to the sealing cover, and the output end of the first motor is fixedly connected to the first rotating shaft. A plurality of stirring rods are fixedly connected to the first rotating shaft.

[0008] To fully filter the waste gas, preferably, arc-shaped parts are symmetrically arranged in the treatment box, and the arc-shaped parts are matched with the mesh plate. When the mesh plate rotates along the axis of the second rotating shaft, at least one of the mesh plates is in contact with the arc-shaped part on one side.

[0009] To facilitate the discharge of the waste gas in the reactor body, further, an air pump is fixedly connected to the treatment box. The air suction end of the air pump is communicated with the exhaust pipe, and a connecting pipe is fixedly connected between the air exhaust end of the air pump and the purification box.

[0010] To prevent the mesh plate from being blocked, preferably, a fixed pipe is fixedly connected to the lower side of the treatment box. The two ends of the fixed pipe in the treatment box are symmetrically and fixedly connected with branch pipes. One-way valves are arranged in the branch pipes, and the upper end of the fixed pipe is communicated with the intake pipe.

[0011] To facilitate the cooling of the water and waste gas in the treatment box, further, an inclined pipe is fixedly connected to the upper end of the fixed pipe. A safety valve is arranged in the inclined pipe. When the negative pressure in the fixed pipe reaches the set value, the gas enters the fixed pipe from the inclined pipe.

[0012] Compared with the prior art, the present utility model provides a reactor with a tail gas absorption and treatment component, having the following beneficial effects:

[0013] 1. For the reactor with a tail gas absorption and treatment component, the waste gas enters the bottom of the treatment box through the intake pipe. At this time, the gas entering the treatment box forms bubbles in the water, and the large bubbles floating upward are separated into multiple small bubbles by the mesh plate, thereby effectively increasing the contact area between the waste gas and the water, and further effectively improving the filtering effect on the waste gas. The filtered gas enters the purification box through the connecting pipe, and the waste gas is purified in the purification box.

[0014] 2. For the reactor with a tail gas absorption and treatment component, the mesh plate rotates along the second rotating shaft through the second motor and the second rotating shaft. The rotating mesh plate squeezes the bubbles in the water in the treatment box, making the bubbles broken and smaller, thereby effectively improving the filtering effect on the waste gas. And when the lower side of the right mesh plate is blocked, the blocked mesh plate moves to the left and the blocked part is located on the upper side. At this time, the blocked part is cleaned by the upward floating bubbles, thereby effectively backwashing the mesh plate and preventing the mesh plate from being blocked and affecting the treatment effect of the waste gas.

[0015] 3. For the reactor with a tail gas absorption and treatment component, the air pump is used for air extraction to discharge the waste gas in the reactor body. And when the negative pressure in the fixed pipe reaches the set value of the safety valve, the outside gas enters the fixed pipe through the inclined pipe. By contacting the outside air with the water in the treatment box, the water and waste gas in the treatment box can be effectively cooled.

[0016] The parts not involved in this device are the same as those in the prior art or can be implemented using the prior art. The utility model effectively increases the contact area between the waste gas and water, thereby effectively improving the filtering effect on the waste gas. And by performing backwashing on the mesh plate, it prevents the mesh plate from being blocked and affecting the treatment effect on the waste gas. Brief Description of the Drawings

[0021] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments.

[0022] Embodiment 1: Refer to Figures 1 - 3 , a reactor with a tail gas absorption and treatment assembly, including: a reactor body 1, and further including: a sealing cover 101, threadedly connected to the reactor body 1; a treatment box 2; a second rotating shaft 202, rotatably arranged in the treatment box 2; a plurality of mesh plates 203, fixedly arranged in a circle on the second rotating shaft 202; a second motor 204, fixedly arranged on one side of the treatment box 2, and the output end of the second motor 204 is fixedly connected to the second rotating shaft 202; an inlet pipe 205, arranged on the sealing cover 101, and the inlet pipe 205 is communicated with the lower end of the treatment box 2; an exhaust pipe 206, arranged on the upper side of the treatment box 2; a purification box 207, fixedly arranged on one side of the treatment box 2, and the input end of the purification box 207 is connected to the exhaust pipe 206.

[0023] A threaded cover 102 is threadedly connected to the sealing cover 101. A first rotating shaft 104 is rotatably arranged in the reactor body 1.

A plurality of stirring rods 105 are fixedly connected to the first rotating shaft 104.

[0024] Arc-shaped parts 201 are symmetrically arranged in the processing box 2, and the arc-shaped parts 201 are matched with the mesh plate 203. When the mesh plate 203 rotates along the axis of the second rotating shaft 202, at least one mesh plate 203 is in contact with the arc-shaped part 201 on one side.

[0025] The waste gas generated by the reaction in the reactor body 1 enters the bottom of the processing box 2 through the intake pipe 205. At this time, the gas entering the processing box 2 forms bubbles in the water, and the upward floating large bubbles are separated into multiple small bubbles through the mesh plate 203, thereby effectively increasing the contact area between the waste gas and the water, and further effectively improving the filtering effect on the waste gas. The filtered gas enters the purification box 207 through the connecting pipe 401, and the waste gas is purified in the purification box 207.

[0026] The second motor 204 and the second rotating shaft 202 are used to make the mesh plate 203 rotate along the second rotating shaft 202. The rotating mesh plate 203 squeezes the bubbles in the water in the processing box 2, making the bubbles broken and smaller, thereby effectively improving the filtering effect on the waste gas. And when the lower side of the right mesh plate 203 is blocked, the blocked mesh plate 203 moves to the left and the blocked part is on the upper side. At this time, the upward floating bubbles are used to clean it, thereby effectively backwashing the mesh plate 203 and preventing the mesh plate 203 from being blocked and affecting the treatment effect of the waste gas.

[0027] Example 2: Refer to Figures 1 - 3 , a reactor with a tail gas absorption and treatment component, which is basically the same as Example 1. Further, an air pump 4 is fixedly connected to the processing box 2. The air suction end of the air pump 4 is communicated with the exhaust pipe 206, and a connecting pipe 401 is fixedly connected between the air exhaust end of the air pump 4 and the purification box 207.

[0028] A fixed pipe 3 is fixedly connected to the lower side of the processing box 2. One end of the fixed pipe 3 in the processing box 2 is symmetrically and fixedly connected with branch pipes 301. One-way valves 302 are arranged in the branch pipes 301, and the upper end of the fixed pipe 3 is communicated with the intake pipe 205.

[0029] An inclined pipe 303 is fixedly connected to the upper end of the fixed pipe 3. A safety valve 304 is arranged in the inclined pipe 303. When the negative pressure in the fixed pipe 3 reaches the set value, the gas enters the fixed pipe 3 from the inclined pipe 303.

[0030] Air is pumped out through the air pump 4 to discharge the waste gas in the reactor body 1. And when the negative pressure in the fixed pipe 3 reaches the set value of the safety valve 304, the outside air enters the fixed pipe 3 through the inclined pipe 303. By contacting the water in the treatment tank 2 with the outside air, the water and waste gas in the treatment tank 2 can be effectively cooled down.

[0031] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
