[0021] As shown in the accompanying Figure 1 to the accompanying Figure 3 As shown:

[0022] The utility model provides a kind of carbon dioxide separation and recovery device, including recovery separation tank 1, exhaust pipe 2, replacement cover 3, carbon dioxide adsorption plate group 4, injection lance 5, multi-angle drive box 6, overhaul cover 7, reciprocating cylinder 8, drive rack 9, driven gear 10, gas injection pipe 11 and spray head 12, recovery separation tank 1 is equipped with gas pipe 2 and is installed with replacement cover 3 on top;Carbon dioxide adsorption plate group 4 is slidably installed in the middle of recovery separation tank 1, one side of carbon dioxide adsorption plate group 4, i.e. the inside one end of recovery separation tank 1 is rotatably installed with a plurality of injection lance 5, any end of each injection lance 5 rotatably passes through recovery separation tank 1, and passes into the multi-angle drive box 6 fixedly installed outside recovery separation tank 1, and is rotatably connected with the gas injection pipe 11 fixedly installed in multi-angle drive box 6, the output end of reciprocating cylinder 8 fixedly installed above multi-angle drive box 6 is fixed with the drive rack 9 slidably installed in it, and the drive rack 9 is engaged with the driven gear 10 fixedly installed on injection lance 5, and each injection lance 5 is provided with a plurality of spray heads 12.

[0023] Further, recovery separation tank 1 adopts center type box structure, which helps to realize efficient use of the internal space of the device. In the inside of recovery separation tank 1, carbon dioxide adsorption plate group 4 is slidably installed through sliding connection structure such as slide, and it is accurately located just below replacement cover 3. In actual production, the slide can be made of wear-resistant metal material, such as stainless steel, to ensure that it is not easily damaged during long-term use and ensure that carbon dioxide adsorption plate group 4 can slide smoothly. Such layout design makes it more convenient to operate when replacing carbon dioxide adsorption plate group 4. Only by opening replacement cover 3, carbon dioxide adsorption plate group 4 can be directly replaced, greatly improving the convenience of maintenance.

[0024] Further, injection lance 5 is vertically arranged at one end inside recovery separation tank 1 and located at one side of carbon dioxide adsorption plate group 4. In specific implementation, injection lance 5 is rotatably installed inside recovery separation tank 1 to ensure stable connection and subsequent multi-angle injection of carbon dioxide. At the same time, exhaust pipe 2 provided on recovery separation tank 1 is located at the other side of carbon dioxide adsorption plate group 4. Such layout forms a clear gas flow path. After mixed gas is sprayed out from injection lance 5 and separated by carbon dioxide adsorption plate group 4, the remaining gas is discharged from exhaust pipe 2, avoiding chaotic flow of gas inside recovery separation tank 1 and improving the efficiency of carbon dioxide separation and recovery.

[0025] Further, a plurality of spray heads 12 are arranged on each injection nozzle 5, and the spray heads 12 are all arranged to face the carbon dioxide adsorption plate group 4. The spray heads 12 can be fixed on the injection nozzle 5 by screwing or gluing, and the spray heads 12 can be made of corrosion-resistant plastic or metal, such as polytetrafluoroethylene or stainless steel. This arrangement allows the mixed gas to be sprayed to the carbon dioxide adsorption plate group 4 with a large coverage area, increasing the contact area between the mixed gas and the carbon dioxide adsorption plate group 4, thereby improving the adsorption effect of carbon dioxide and further improving the efficiency of separation and recovery.

[0026] Further, a plurality of spray heads 12 are arranged on each injection nozzle 5, and the spray heads 12 are all arranged to face the carbon dioxide adsorption plate group 4. The spray heads 12 can be fixed on the injection nozzle 5 by screwing or gluing, and the spray heads 12 can be made of corrosion-resistant plastic or metal, such as polytetrafluoroethylene or stainless steel. This arrangement allows the mixed gas to be sprayed to the carbon dioxide adsorption plate group 4 with a large coverage area, increasing the contact area between the mixed gas and the carbon dioxide adsorption plate group 4, thereby improving the adsorption effect of carbon dioxide and further improving the efficiency of separation and recovery.

[0027] Further, the gas injection pipe 11 fixedly installed on one side inside the multi-angle drive box 6 is connected to the injection nozzle 5 through a rotary sealing joint. The gas injection pipe 11 is made of a metal pipe, and sealing materials such as sealing rubber rings are used at the connection part to ensure that the gas does not leak. The upper end of the gas injection pipe 11 penetrates out of the multi-angle drive box 6, and the penetrating end is the gas inlet pipe. The mixed gas enters the gas injection pipe 11 from the gas inlet pipe, then flows into the injection nozzle 5 through the rotary sealing joint, and finally is sprayed out of the spray head 12, providing a gas source for carbon dioxide separation and recovery.

[0028] The working principle is as follows: mixed gas enters the gas injection pipe 11 from the gas inlet pipe outside the multi-angle drive box 6. The gas injection pipe 11 is made of a metal pipe and is connected to the injection nozzle 5 through a rotary sealing joint, and sealing materials such as sealing rubber rings are used at the connection part to prevent gas leakage. The mixed gas flows into each injection nozzle 5 through this channel, ensuring stable supply of the gas source.

[0029] The reciprocating air cylinder 8 fixedly installed above the multi-angle driving box 6 is the key to realize multi-angle spraying. After the reciprocating air cylinder 8 is started, the output end thereof drives the fixed driving rack 9 to make reciprocating linear motion in the multi-angle driving box 6. Each injection nozzle 5 rotating into one end of the multi-angle driving box 6 is provided with a driven gear 10, and the driven gears 10 are vertically arranged and simultaneously engaged with the driving rack 9. When the driving rack 9 slides, all the driven gears 10 are driven to rotate synchronously, thereby enabling the injection nozzle 5 to rotate around the rotation axis thereof. Since a plurality of nozzles 12 facing the carbon dioxide adsorption plate group 4 are horizontally arranged on each injection nozzle 5, the rotation of the injection nozzle 5 enables the nozzles 12 to spray the mixed gas at multiple angles, greatly improving the uniformity of the mixed gas spraying and increasing the contact area with the carbon dioxide adsorption plate group 4.

[0030] The mixed gas sprayed from the nozzles 12 rushes to the carbon dioxide adsorption plate group 4. The recovery separation box 1 adopts a center type box structure, and the carbon dioxide adsorption plate group 4 is installed in the recovery separation box 1 through a slide way and located directly below the replacement cover 3. The injection nozzle 5 is vertically arranged on one side of the carbon dioxide adsorption plate group 4, and the exhaust pipe 2 is located on the other side. The carbon dioxide is adsorbed in the mixed gas at the carbon dioxide adsorption plate group 4, and the remaining gas is discharged through the exhaust pipe 2, forming a clear gas flow path, avoiding the chaotic flow of gas in the box, and improving the carbon dioxide separation and recovery efficiency.

[0031] When the adsorption capacity of the carbon dioxide adsorption plate group 4 decreases or is damaged, the replacement cover 3 above the recovery separation box 1 can be opened for replacement. Since the carbon dioxide adsorption plate group 4 is slidably installed through a slide way and located directly below the replacement cover 3, the operation is simple and convenient, and the replacement can be completed by directly sliding out the old plate and sliding in the new plate, thereby reducing the maintenance time and cost and ensuring the continuous and stable operation of the device.

[0032] The technical scheme of the utility model or the technical scheme inspired by the technical scheme of the utility model by those skilled in the art is designed to achieve the above technical effects, and falls within the protection scope of the utility model.
