Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas recovery, in particular to a waste gas recycling device of a composite flame retardant. Background Art

[0002] During the production process of composite flame retardants, a large amount of waste gas containing volatile components will be generated. Under the traditional production model, these waste gases are usually discharged directly into the atmosphere, which not only causes waste of resources, but also pollutes the environment. For example, some volatile substances may form acid rain or photochemical smog and other hazards. With the increasingly stringent environmental protection requirements and the continuous popularization of the concept of resource recycling, it is urgent to develop a waste gas recycling device for composite flame retardants in order to achieve energy conservation and emission reduction, reduce production costs, and meet the needs of sustainable industrial production, while reducing the negative impact on the surrounding environment and residents' lives. During the preparation of composite flame retardants, a large amount of unreacted carbon dioxide will be discharged as waste gas.

[0003] However, during use, the existing waste gas recycling device of composite flame retardants is not convenient for separating carbon dioxide and water vapor in the waste gas, resulting in a large amount of water in the recovered carbon dioxide. This water not only reduces the purity of the carbon dioxide, but also reacts with the carbon dioxide to form carbonic acid, corroding the equipment and causing economic losses. Utility Model Content

[0004] The purpose of the utility model is to provide a waste gas recycling device for a composite flame retardant. By setting a separation mechanism, the utility model solves the problem that the existing waste gas recycling device for a composite flame retardant is not convenient for separating carbon dioxide and water vapor in the waste gas during use, resulting in the recovered carbon dioxide containing a large amount of water. This water not only reduces the purity of the carbon dioxide, but also reacts with the carbon dioxide to form carbonic acid, corroding equipment and causing economic losses.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a waste gas recycling device for composite flame retardants, comprising a chassis, on which a separation mechanism and a circulation mechanism are arranged;

[0007] A sealed door is hingedly provided on the left side of the chassis, the separation mechanism includes a connecting pipe fixedly connected to the top of the chassis, the inner wall of the connecting pipe is fixedly connected to a silicone block, the top of the chassis is fixedly connected to a thin tube, the right side of the thin tube is connected to the connecting pipe, the circulation mechanism includes an air pump fixedly connected to the top of the chassis, and the right side of the connecting tube is connected to the air pump.

[0008] Furthermore, the inner wall of the chassis is fixedly connected to a bellows, the top of the bellows is connected with a thick tube, the outer wall of the thick tube is connected to the thin tube, the inner wall of the bellows is fixedly connected to two brackets, and the inner walls of the two brackets are rotatably connected to a rotating shaft.

[0009] Furthermore, a fan is fixedly connected to the outer wall of the rotating shaft, a motor sleeve is fixedly connected to the bottom of the bracket below, a motor is fixedly connected to the inner wall of the motor sleeve, and an output shaft of the motor is fixedly connected to the rotating shaft through a coupling.

[0010] Furthermore, a storage tank is fixedly connected to the bottom of the inner wall of the chassis, and a pipe 1 is provided on the top of the storage tank. The top of the pipe 1 extends outside the chassis, and the top of the pipe 1 is connected to the air pump.

[0011] Furthermore, a second pipe is provided on the left side of the storage tank, a reaction pool is provided at the bottom of the inner wall of the chassis, the left side of the second pipe extends into the reaction pool, and the bottom of the bellows is connected to the reaction pool.

[0012] The utility model has the following beneficial effects:

[0013] 1. By setting up a separation mechanism, during the reaction, a large amount of carbon dioxide will escape to the top of the raw materials without participating in the reaction in time. At this time, the motor can be started to rotate its output shaft, thereby driving the fan to rotate through the shaft. The wind force generated by the fan rotation will drive the exhaust gas in the chassis to be sucked into the thick pipe through the bellows, and then into the thin pipe. When the exhaust gas enters the thin pipe from the thick pipe, the speed will increase. Subsequently, the exhaust gas will enter the connecting pipe, and the silica gel block in it will absorb the water vapor in the exhaust gas, so that the unreacted carbon dioxide in the exhaust gas generated by the production process can be separated from the water vapor, preventing the water vapor from reducing the purity of the carbon dioxide. At the same time, it can avoid the situation where the water formed after the water vapor condenses and reacts with the carbon dioxide to corrode the device, thereby reducing economic losses;

[0014] 2. By setting up a circulation mechanism, open the sealed door and pour the reaction raw materials into the reaction pool, then close the sealed door and open the storage tank, so that the high-concentration carbon dioxide gas stored inside can be transported to the reaction pool through pipeline 2. The carbon dioxide will react with the raw materials in the reaction pool, and then the carbon dioxide will be recovered through the separation mechanism. Then the air pump can be started to allow the carbon dioxide to enter the storage tank through pipeline 1 under its action, so that the residual carbon dioxide that failed to participate in the reaction in time can be re-compressed and recycled, avoiding waste and ensuring that only high-concentration carbon dioxide participates in the reaction, thereby increasing the reaction speed.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom of the lower bracket 206 is fixedly connected to a motor sleeve 209, and the inner wall of the motor sleeve 209 is fixedly connected to a motor 210. The output shaft of the motor 210 is fixedly connected to the rotating shaft 207 through a coupling. By setting up a separation mechanism 2, the unreacted carbon dioxide and water vapor in the exhaust gas generated in the production process can be separated to prevent the water vapor from reducing the purity of the carbon dioxide. At the same time, it can avoid the situation where the water formed after the water vapor condenses and the carbon dioxide reacts with the corrosion of the device, thereby reducing economic losses.

[0026] The circulation mechanism 3 includes an air pump 301 fixedly connected to the top of the chassis 1, the right side of the connecting pipe 201 is connected to the air pump 301, and a storage tank 302 is fixedly connected to the bottom of the inner wall of the chassis 1. The top of the storage tank 302 is connected to a pipe 1 303, the top of the pipe 1 303 extends to the outside of the chassis 1, the top of the pipe 1 303 is connected to the air pump 301, and the left side of the storage tank 302 is connected to a pipe 2 304. A reaction pool 305 is provided at the bottom of the inner wall of the chassis 1, the left side of the pipe 2 304 extends into the reaction pool 305, and the bottom of the bellows 204 is connected to the reaction pool 305. By setting up the circulation mechanism 3, the residual carbon dioxide that fails to participate in the reaction in time during the reaction can be recompressed and recycled, avoiding waste and ensuring that the carbon dioxide participating in the reaction is high-concentration carbon dioxide, thereby improving the reaction speed.

[0027] A specific application of this embodiment is: when in use, first open the sealed door 101 to pour the reaction raw materials into the reaction pool 305, then close the sealed door 101, open the storage tank 302, and make it transport the high-concentration carbon dioxide gas stored inside through the pipeline 304 to the reaction pool 305, wherein the model of the storage tank 302 is CFL-15-2.16, and its working principle is to maintain the internal low temperature through the vacuum insulation layer, control the pressure with a safety valve, and feed and discharge materials through the pipeline, and assist in monitoring with a liquid level meter.

When the exhaust gas enters the thin pipe 203 from the thick pipe 205, the speed will increase. Subsequently, the exhaust gas will enter the connecting pipe 201, and the silicone block 202 therein will absorb the water vapor in the exhaust gas. Then the air pump 301 can be started. The model of the air pump 301 is FB-STA25CL-S. Its working principle is to use compressed air as a power source. When the compressed air enters the drive cylinder, it pushes the piston to move. The piston drives the piston of the boosting cylinder through the connecting component to pressurize the carbon dioxide, thereby achieving compression, so that the carbon dioxide will enter the storage tank 302 through pipe 1 303 under its action, thereby achieving recycling.
