Description

Technical Field

[0001] This utility model relates to the technical field of carbon dioxide treatment devices, and in particular to a device for industrial carbon dioxide adsorption and desorption. Background Technology

[0002] Large-scale carbon dioxide emissions primarily contribute to the greenhouse effect. For chemical production, carbon dioxide can be recycled and reused, which not only reduces environmental pollution but also improves resource utilization efficiency. Carbon dioxide capture technologies can be categorized into several types, including chemical absorption, physical absorption, physical adsorption, membrane separation, and cryogenic separation. Activated carbon has excellent adsorption properties for carbon dioxide, and the adsorbed carbon dioxide will be stably stored in the pores of the activated carbon.

[0003] However, existing industrial carbon dioxide adsorption and desorption devices only have one set of adsorption mechanisms, that is, multiple activated carbon adsorption plates adsorb carbon dioxide in flue gas. After adsorption is completed, the multiple activated carbon adsorption plates are placed in the desorption zone for heating and desorption. Adsorption and desorption cannot be carried out simultaneously, which is inconvenient to use and leads to low adsorption and desorption efficiency of carbon dioxide. At the same time, when the activated carbon adsorption plates adsorb for a long time, their adsorption performance will decrease. At this time, the machine needs to be stopped and the activated carbon adsorption plates are transferred to the desorption zone for desorption. This results in low flue gas treatment efficiency and weak continuous processing capacity of the device. Therefore, it is necessary to design an industrial carbon dioxide adsorption and desorption device that can facilitate simultaneous adsorption and desorption. Utility Model Content

[0004] In order to overcome the shortcomings of existing industrial carbon dioxide adsorption and desorption devices, which only have one set of adsorption mechanisms, that is, adsorbing carbon dioxide in flue gas through multiple activated carbon adsorption plates, and then placing multiple activated carbon adsorption plates into the desorption zone for heating and desorption after adsorption is completed, it is not convenient to carry out adsorption and desorption simultaneously, thus making it inconvenient to use and resulting in low adsorption and desorption efficiency of carbon dioxide, one of the purposes of this utility model is to provide an industrial carbon dioxide adsorption and desorption device.

[0005] One of the objectives of this utility model is achieved through the following technical solution: an industrial carbon dioxide adsorption and desorption device, comprising a base; a fixed tube is fixedly connected to the upper surface of the base, a housing is fixedly connected to the upper surface of the fixed tube, a support tube is fixedly connected to one side of the upper surface of the housing, an inlet tube is fixedly connected to the upper surface of the support tube, a baffle is inserted into the middle of the inner wall of the housing, the baffle divides the housing into an adsorption zone and a desorption zone from left to right; an adsorption mechanism one and an adsorption mechanism two are slidably connected to the inner walls of the adsorption zone and the desorption zone, respectively; the adsorption mechanism one includes a fixed plate symmetrically fixedly connected to the inner walls of the adsorption zone and the desorption zone, a support frame is slidably connected to the outer surface of the fixed plate, activated carbon adsorption plates are equidistantly installed on one side of the support frame, a sliding groove is opened on the inner wall of the housing near the support frame, a moving groove is fixedly connected to the inner wall of the sliding groove, a sliding plate is slidably connected to the inner wall of the moving groove, and a screw is rotatably connected to the inner wall of the moving groove. This design facilitates the alternating adsorption of carbon dioxide in flue gas by adsorption mechanism one and adsorption mechanism two. When adsorption mechanism one is adsorbing carbon dioxide in the flue gas in the adsorption zone, adsorption mechanism two is in the desorption zone. After adsorption mechanism one has adsorbed carbon dioxide for a certain period of time, adsorption mechanism two is moved into the adsorption zone for adsorption, and adsorption mechanism one is moved into the desorption zone to desorb carbon dioxide on the activated carbon adsorption plate. This alternating adsorption of carbon dioxide effectively improves the adsorption and desorption efficiency.

[0006] According to the aforementioned industrial carbon dioxide adsorption and desorption device, the structure and working principle of the second adsorption mechanism are consistent with those of the first adsorption mechanism. The support frame is connected to the sliding plate by screws, the screw passes through the sliding plate and is threadedly connected to it, and the support frame is slidably connected to the fixed plate. This facilitates alternating use.

[0007] According to the aforementioned industrial carbon dioxide adsorption and desorption device, a sealing plate is installed on one inner wall of the housing using screws. This facilitates sealing of the housing and prevents carbon dioxide flue gas leakage.

[0008] According to the aforementioned industrial carbon dioxide adsorption and desorption device, a shut-off valve is installed on the upper surface of the inlet pipe to facilitate the opening and closing of the inlet pipe.

[0009] According to the aforementioned industrial carbon dioxide adsorption and desorption device, an electric heating tube is installed on the inner wall of the desorption zone, a temperature controller body is installed on the front surface of one side of the housing, and a temperature sensor is installed on the inner top wall of the desorption zone. Both the electric heating tube and the temperature sensor are electrically connected to the temperature controller body. This facilitates heating of the desorption zone, thereby heating and desorbing the carbon dioxide adsorbed on the activated carbon adsorption plate two of adsorption mechanism one or adsorption mechanism two, making it convenient to use.

[0010] According to the aforementioned industrial carbon dioxide adsorption and desorption device, a cylinder is fixedly connected to one upper surface of the base. A conveying pipe is fixedly connected to the side wall of the fixed pipe near the cylinder. The other end of the conveying pipe extends through the side wall of the cylinder and into the interior of the cylinder. A one-way valve is installed on the upper surface of the conveying pipe. This facilitates the conveying of the adsorbed flue gas into the cylinder for collection via the conveying pipe.

[0011] According to the aforementioned industrial carbon dioxide adsorption and desorption device, a discharge pipe is fixedly connected to the middle of the upper surface of the cylinder. This facilitates the discharge of flue gas from the cylinder through the discharge pipe for further processing.

[0012] According to the aforementioned industrial carbon dioxide adsorption and desorption device, a second conveying pipe is fixedly connected to the upper surface of one side of the desorption zone, and a carbon dioxide collection cylinder is fixedly connected to the other end of the second conveying pipe. The carbon dioxide collection cylinder is fixedly connected to the base, and a second one-way valve is installed on the upper surface of the second conveying pipe. This facilitates the conveying of the desorbed carbon dioxide through the second conveying pipe into the carbon dioxide collection cylinder for collection and storage.

[0013] The above-mentioned solution has the following beneficial effects:

[0014] 1. By setting up adsorption mechanism one and adsorption mechanism two, compared with the prior art, this device can alternately enter the adsorption zone and the desorption zone to simultaneously adsorb and desorb carbon dioxide. This alternating operation avoids the problem of incomplete adsorption of carbon dioxide in flue gas caused by prolonged adsorption of activated carbon adsorption plates on adsorption mechanism one or adsorption mechanism two. This effectively improves the efficiency of carbon dioxide adsorption and desorption, and at the same time improves the practicality and continuity of the device.

[0015] 2. By incorporating an electric heating element, a temperature sensor, and a temperature controller, the desorption zone can be heated to a suitable temperature for desorption of carbon dioxide adsorbed on adsorption mechanism one or adsorption mechanism two. This design is convenient to use and allows for easy temperature control, resulting in more complete carbon dioxide desorption.

A housing 3 is fixedly connected to the upper surface of the fixing pipe 2. A support pipe 4 is fixedly connected to one side of the upper surface of the housing 3. An inlet pipe 5 is fixedly connected to the upper surface of the support pipe 4. A baffle 6 is inserted into the middle of the inner wall of the housing 3, dividing the housing 3 into an adsorption zone 301 and a desorption zone 302 from left to right. Adsorption mechanism 1 7 and adsorption mechanism 2 8 are slidably connected to the inner walls of the adsorption zone 301 and the desorption zone 302, respectively. Adsorption mechanism 1 7 includes symmetrically fixed connections. A fixed plate 71 is attached to the inner wall of the adsorption zone 301 and the desorption zone 302. A support frame 72 is slidably connected to the outer surface of the fixed plate 71. Activated carbon adsorption plates 73 are equidistantly installed on one side of the support frame 72. A sliding groove 74 is provided on the inner wall of the housing 3 near the support frame 72. A movable groove 75 is fixedly connected to the inner wall of the sliding groove 74. A sliding plate 76 is slidably connected to the inner wall of the movable groove 75. A screw 77 is rotatably connected to the inner wall of the movable groove 75. The structure and working principle of the second adsorption mechanism 8 are consistent with those of the first adsorption mechanism 7. The support frame 72 is connected to the sliding plate 76 by screws. The connection is as follows: screw 77 passes through slide plate 76 and is threadedly connected to slide plate 76; support frame 72 is slidably connected to fixed plate 71; a sealing plate 9 is installed on one side inner wall of box 3 by screws; a shut-off valve 10 is installed on the upper surface of inlet pipe 5; an electric heating tube 11 is provided on the inner wall of analytical zone 302; a temperature controller body 12 is installed on one side front surface of box 3; a temperature sensor 13 is installed on the inner top wall of analytical zone 302; both electric heating tube 11 and temperature sensor 13 are electrically connected to temperature controller body 12; and a cylinder is fixedly connected to one side upper surface of base 1. 14. A conveying pipe 15 is fixedly connected to the side wall of the fixed pipe 2 near the cylinder 14. The other end of the conveying pipe 15 passes through the side wall of the cylinder 14 and extends into the inside of the cylinder 14. A one-way valve 16 is installed on the upper surface of the conveying pipe 15. An outlet pipe 17 is fixedly connected to the middle of the upper surface of the cylinder 14. A conveying pipe 28 is fixedly connected to the upper surface of one side of the analytical zone 302. A carbon dioxide collection cylinder 19 is fixedly connected to the other end of the conveying pipe 28. The carbon dioxide collection cylinder 19 is fixedly connected to the base 1. A one-way valve 20 is installed on the upper surface of the conveying pipe 28.

[0028] This configuration, with multiple activated carbon adsorption plates 73 on adsorption mechanism 2 8 and adsorption mechanism 1 7 arranged alternately, ensures sliding between adsorption mechanism 1 7 and adsorption mechanism 2 8. The alternating arrangement of adsorption mechanism 1 7 and adsorption mechanism 2 8 allows for simultaneous adsorption and desorption of carbon dioxide in the flue gas, effectively improving work efficiency. It also avoids the problem of decreased adsorption capacity caused by prolonged adsorption by multiple activated carbon adsorption plates 73 on adsorption mechanism 1 7, thus significantly enhancing the practicality and convenience of the device. Furthermore, the one-way valve 16 and one-way valve 20 prevent flue gas from re-entering the adsorption zone 301 through the cylinder 14 and prevent desorbed carbon dioxide from entering the desorption zone 302 from the carbon dioxide collection cylinder 19, achieving unidirectional flow and facilitating operation.

[0029] Working principle: Flue gas is introduced into the adsorption zone 301 through the inlet pipe 5 and the support pipe 4. The flue gas flows from top to bottom and is adsorbed by multiple activated carbon adsorption plates 73 on the adsorption mechanism 7. The activated carbon adsorption plates 73 adsorb carbon dioxide in the flue gas. After adsorption, the flue gas enters the cylinder 14 through the fixed pipe 2 and the conveying pipe 15 and is discharged through the outlet pipe 17 for further processing. When the adsorption mechanism 7 has been adsorbing for a long time and its adsorption capacity is affected, the inlet pipe 5 is cut off by the shut-off valve 10, so that the flue gas no longer enters the adsorption zone 301. The baffle 6 is removed from the box 3. The screw 77 of the adsorption mechanism 7 is rotated to drive the slide plate 76 to slide in the moving groove 75 and the sliding groove 74. The slide plate 76 drives the support frame 72 to slide on the fixed plate 71, thereby moving the adsorption mechanism 7 into the desorption zone 302 for desorption. The temperature sensor 13, the temperature controller body 12 and the electric heating tube 11 heat the desorption zone 302 to a certain temperature, thereby heating the flue gas. The method involves desorbing the carbon dioxide adsorbed by the activated carbon adsorption plate 73 on the adsorption mechanism 7, thereby improving the adsorption capacity of the activated carbon adsorption plate 73. The desorbed carbon dioxide is then transported to the carbon dioxide collection cylinder 19 through the delivery pipe 18 for collection. Simultaneously, when the adsorption mechanism 7 moves to the desorption zone 302, the screw 77 of the adsorption mechanism 8 is rotated, which drives the support frame 72 to move through the slide plate 76, thereby moving the adsorption mechanism 8 into the adsorption zone 301 for use. After the adsorption mechanism 7 and the adsorption mechanism 8 have been alternated, the baffle 6 is inserted into the box 3 for partitioning to prevent flue gas from entering the desorption zone 302. Then, the shut-off valve 10 is opened, and the flue gas re-enters the adsorption zone 301 for carbon dioxide adsorption by the adsorption mechanism 8. The above operation is repeated alternately, thereby improving the adsorption and desorption efficiency of carbon dioxide in the flue gas by the adsorption mechanism 7 and the adsorption mechanism 8. The operation is convenient, and the alternating operation of carbon dioxide adsorption and desorption effectively improves the working efficiency.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
