Description

Technical Field

[0001] The present invention relates to the field of carbon dioxide purification, in particular to a device for purifying carbon dioxide by recycling waste resources. Background Art

[0002] In the current existing technology, the organic matter in the crushed garbage is converted into gas through pyrolysis or gasification, and then the gas is pressurized and transported to the carbon dioxide purification device through a fan. The purification device is equipped with an adsorption module made of adsorption material. Commonly used adsorption materials are calcium oxide adsorbent materials, activated carbon, and zeolite molecular sieves. Zeolite molecular sieves generate a "surface force" on the solid surface through molecular attraction. When carbon dioxide gas flows through, the molecules in it will collide with the surface of the adsorption material and gather there. Subsequently, the carbon dioxide on the zeolite molecular sieve is desorbed through a desorption and regeneration process, thereby realizing the recovery and purification of carbon dioxide from garbage resources;

[0003] The desorption regeneration process is to reduce the pressure around the molecular sieve so that the carbon dioxide molecules adsorbed on the molecular sieve can be spontaneously desorbed at a lower pressure, thereby completing the regeneration of the zeolite molecular sieve.

[0004] However, when the adsorption module of the existing carbon dioxide purification device reaches the limit of its adsorption capacity, the staff needs to shut down the device and replace it with a new adsorption module, which makes it inconvenient for the staff to use. Therefore, to address the above problem, a device for purifying carbon dioxide by recycling waste resources is proposed. Summary of the Invention

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Specific examples are given below.

[0028] See also Figure 1-4 As shown, a device for purifying carbon dioxide by recycling waste resources includes a warehouse body 11, wherein a plurality of zeolite molecular sieve modules are arranged inside the warehouse body 11, and air ducts 13 are fixedly connected on both sides of the warehouse body 11, and a support 12 is rotatably connected to the interior of the warehouse body 11, and a plurality of adsorption chambers 18 are opened on the support 12, and the zeolite molecular sieve modules are installed inside the adsorption chamber 18, and through holes corresponding to the air ducts 13 are opened on both sides of the adsorption chamber 18; a frame 16 is rotatably connected to the warehouse body 11, and a motor 17 is fixed to the frame 16, and the output end of the motor 17 is fixedly connected to the support 12, and the motor 17 can drive the support 12 to rotate in the warehouse body 11; a vacuum pump 14 is fixedly connected to the bottom of the frame 16, and a negative pressure pipe 15 is fixedly connected between the air inlet end of the vacuum pump 14 and the warehouse body 11, and the vacuum pump 14 can form a negative pressure inside the adsorption chamber 18;

[0029] When in use, the bin body 11 is divided into an adsorption area corresponding to the air duct 13 and a desorption area installed with a negative pressure tube 15. The motor 17 is a servo motor 17, which can drive the support 12 to rotate, thereby driving the multiple adsorption chambers 18 on the support 12 to rotate and switch to communicate with the air duct 13 or the negative pressure tube 15. When the through holes on both sides of the adsorption chamber 18 correspond to the air duct 13, the pressurized gas is injected into the adsorption chamber 18 through the air duct 13. After the adsorption chamber 18 rotates to communicate with the negative pressure tube 15, it is extracted by the vacuum pump 14, so that the dioxygen adsorbed on the molecular sieve is Carbon dioxide molecules spontaneously desorb at a lower pressure to complete the regeneration of the zeolite molecular sieve. Relying on the multiple adsorption chambers 18, when the motor 17 drives the support 12 to rotate, it drives the adsorption chamber 18 to switch to adsorption and desorption regeneration, thereby reducing the need for staff to shut down and replace new adsorption modules, making it convenient for staff to use. The zeolite molecular sieve module is composed of a whole piece of zeolite molecular sieve or multiple pieces of plate-shaped zeolite molecular sieves stacked together. The zeolite molecular sieve module is made of high-temperature adsorption material calcium oxide or low-temperature adsorption material zeolite molecular sieve.

[0030] Further, such as Figure 1-4As shown, the zeolite molecular sieve module is composed of multiple zeolite molecular sieve plates 21, which are installed inside the adsorption chamber 18. A heat conducting plate 22 is installed between two adjacent zeolite molecular sieve plates 21, and a heat conducting pipe 23 is fixed to the heat conducting plate 22; a plurality of liquid injection components are installed on the warehouse body 11, and the liquid injection components can inject heat exchange liquid into the heat conducting pipe 23. When adsorbing carbon dioxide, low-temperature heat exchange liquid is injected to cool the heat conducting plate 22. When desorbing carbon dioxide, high-temperature heat exchange liquid is injected to heat the heat conducting plate 22; when in use, heat exchange liquid flows in the heat conducting pipe 23 to heat the heat conducting pipe 23 and the heat conducting plate 22, and when desorbing carbon dioxide, high-temperature heat exchange liquid is injected to heat the heat conducting plate 22. When the heat transfer plate 22 is heated, a high-temperature heat exchange liquid is injected to heat the heat conducting plate 22. The zeolite molecular sieve plate 21 is a low-temperature adsorption material. Its adsorption capacity for carbon dioxide will decrease at high temperatures. The above-mentioned heating can facilitate the desorption of carbon dioxide. By means of heat transfer through the heat conducting plate 22, it can facilitate heat exchange in the adsorption chamber 18 where the vacuum pump 14 sucks and causes a lower pressure. When adsorbing carbon dioxide, a low-temperature heat exchange liquid is injected to cool the heat conducting plate 22, thereby quickly cooling the zeolite molecular sieve plate 21 and reducing the problem of cooling at the central position inside the plate. The zeolite molecular sieve plate 21 can also be maintained at a low temperature, thereby facilitating the adsorption of carbon dioxide by the zeolite molecular sieve plate 21.

[0031] Further, such as Figure 1-4 As shown, the liquid injection assembly includes a cylinder 33, a cannula 34 connected to a heat exchange liquid conveying pipeline, and a connecting seat 32. A plurality of supports 12 are fixedly connected to the surface of the warehouse body 11. The cylinder 33 is fixedly connected to the support 12. The output end of the cylinder 33 is fixedly connected to a transverse plate. The cannula 34 is fixedly connected to the transverse plate. Both ends of the plurality of heat conducting pipes 23 are fixedly connected to connecting pipes 31. The connecting seat 32 is fixedly connected to the connecting pipe 31. A sliding hole for sliding the cannula 34 is opened on the warehouse body 11. The cylinder 33 can drive the cannula 34 through the sliding hole and insert it into the connecting seat 32; when in use, the adsorption area and desorption area of ​​the warehouse body 11 are both equipped with heat exchange components, which rely on the cylinder 33 to drive the cross plate to move, so that the insert 34 extends from the sliding hole on the warehouse body 11 and is inserted into the corresponding connecting seat 32, thereby connecting the insert 34 and the connecting seat 32, and the connecting seat 32 is connected to multiple heat-conducting pipes 23 through the connecting pipe 31 to transport heat exchange liquid. The heat exchange liquid pipeline is connected to the water pump, and the water pump transports the heated heat exchange liquid or the cooled heat exchange liquid to the insert 34 connected to the heat exchange liquid pipeline.

[0032] Further, such as Figure 4-5As shown, a cavity 42 is provided inside the heat conducting plate 22, and the heat conducting pipe 23 passes through the wall of the cavity 42 and is fixed thereto, and the heat conducting pipe 23 is located inside the cavity 42, and a plurality of air holes 41 are provided on both sides of the cavity 42; during adsorption, since carbon dioxide is adsorbed after the air flow passes through the zeolite molecular sieve plate 21, the uniformity of the air flow distribution will decrease. In this embodiment, the air flow passes through the zeolite molecular sieve plate 21 and then enters the cavity 42 through the air holes 41, and then flows in the cavity 42, and then is distributed and flows out through the air holes 41 on the other side, which plays a role in uniform distribution of the air flow, and the air flow flowing in the cavity 42 can contact the heat conducting pipe 23, which is convenient for cooling the air flow.

[0033] Further, such as Figure 5 As shown, the heat pipe 23 is fixed with a heat conducting seat 51 corresponding to the position of the air hole 41, and the heat conducting seat 51 is fixed with a rubber membrane 52. The space between the rubber membrane 52 and the heat conducting seat 51 is filled with an expansion liquid. When the heat conducting plate 22 is heated, the expansion liquid vaporizes to expand the rubber membrane 52 to block the air hole 41. When the heat conducting plate 22 is cooled, the expansion liquid liquefies and the rubber membrane 52 contracts to release the blockage of the air hole 41. When in use, since the air flow will flow in the cavity 42, in order to facilitate the flow, the heat conducting pipe 23 needs to be suspended in the air. The cavity 42 is supported and fixed by a porous bracket, but after vacuuming, the cavity 42 loses gas to form heat convection to assist heat exchange between the heat pipe 23 and the heat conducting plate 22, thereby affecting the temperature rise of the heat conducting plate 22. In this embodiment, when the heat conducting plate 22 is heated, the expansion liquid vaporizes, causing the rubber membrane 52 to expand to block the pores 41, thereby reducing the outflow of gas in the cavity 42 when vacuuming, thereby facilitating heat exchange between the heat pipe 23 and the heat conducting plate 22. The expansion liquid is one of ethyl acetate, methanol, and ethanol.

[0034] Further, such as Figure 5As shown, a vertical hole 64 is provided on the heat-conducting seat 51; the rubber membrane 52 is annular and has a middle hole 63 formed in the middle. A rubber ring 62 is sleeved on the middle of the rubber membrane 52. The rubber ring 62 can shrink the middle of the rubber membrane 52 to block the middle hole 63. Elastic membranes 61 are fixed between the two ends of the rubber membrane 52 and the heat-conducting seat 51. An expansion cavity 65 is formed between the two ends of the rubber membrane 52 and the heat-conducting seat 51 through the elastic membrane 61. The expansion liquid is filled in the expansion cavity 65. During desorption, after the pores 41 are blocked, the heat-conducting plate 22 will form a The closed plate is sandwiched between the zeolite molecular sieve plates 21, which will affect the discharge of carbon dioxide through the zeolite molecular sieve plates 21. In this embodiment, the middle part of the rubber membrane 52 is made of hard rubber material, and the expansion chambers 65 at both ends expand and fit with the side walls of the cavity 42, and pull the middle part of the rubber membrane 52 to open the middle part, and then the pores 41 and the middle hole 63 in the middle of the rubber membrane 52 are connected, thereby sealing the cavity 42 and allowing the carbon dioxide to flow through. When the temperature drops, the rubber ring 62 can shrink the middle part of the rubber membrane 52 to seal the middle hole 63.

[0035] Further, such as Figure 5 As shown, the air hole 41 is fixedly connected to an air inlet seat 71 on one side close to the heat conducting seat 51. The air inlet seat 71 has a hollow structure design, and the end of the air inlet seat 71 is inserted into the middle hole 63. A plurality of air grooves 72 are provided on the air inlet seat 71. The two ends of the vertical hole 64 and the air inlet seat 71 are fixedly connected to a convex ring 73 at a position corresponding to one end of the middle hole 63. The gap between the convex ring 73 and the exhaust seat is adapted to the thickness of the rubber membrane 52, and the rubber membrane 52 can slide between the convex ring 73 and the exhaust seat. When in use, the convex ring 73 The gap between the rubber membrane 52 and the exhaust seat is adapted to the thickness of the rubber membrane 52. The expansion chambers 65 at both ends of the rubber membrane 52 expand, which will pull the middle of the rubber membrane 52, so that the middle hole 63 in the middle of the rubber membrane 52 is connected. The rubber membrane 52 can slide between the convex ring 73 and the exhaust seat, so as to limit the expansion of the rubber membrane 52, thereby reducing the situation where the middle of the reverse vertical hole 64 expands to block the middle hole 63. The rubber membrane 52 expands along the intake seat 71 to cover the air groove 72, thereby blocking the air groove 72.

[0036] Further, such as Figure 1-4 As shown, a guide rod 82 is fixed to the transverse plate, and the guide rod 82 passes through the side wall of the warehouse body 11 and is slidably connected thereto. A positioning hole 81 is opened on the support 12 at a position corresponding to the guide rod 82, and the guide rod 82 can be inserted into the positioning hole 81 and slidably connected thereto; when in use, the cylinder 33 drives the transverse plate to move the cannula 34, which drives the guide rod 82 to be inserted into the corresponding positioning hole 81, so that the support 12 can be fixed, its stability is improved, and the stability of the connection between the cannula 34 and the connecting seat 32 is improved.

[0037] Further, such as Figure 4 As shown, grooves 91 are provided on the surface of the support 12 and on both sides of the adsorption chamber 18. Two fixed arms 92 are rotatably connected in the adsorption chamber 18, and a sealing film 93 is fixed to the groove 91; when in use, the fixed arms 92 make the sealing film 93 bulge outward, and at the same time, there is a certain gap between the sealing film 93 and the inner wall of the warehouse body 11. When the support 12 rotates, it does not fit with the inner wall of the warehouse body 11, reducing the pattern of the sealing film 93. When the adsorption chamber 18 is under negative pressure, the pressure will cause the sealing film 93 to deform, and the fixed arms 92 will rotate to squeeze the sealing film 93 to fit with the inner wall of the warehouse body 11, thereby improving the sealing effect of the adsorption chamber 18.

[0038] Further, such as Figure 5 As shown, the air inlet seat 71 is arranged in a conical structure, and the two ends of the rubber membrane 52 are sleeved on the surface of the air inlet seat 71; when in use, relying on the above arrangement, the two ends of the rubber membrane 52 can be easily expanded to seal the air groove 72, thereby facilitating sealing.

[0039] Working principle: When in use, the bin body 11 is divided into an adsorption area corresponding to the air duct 13 and a desorption area installed with a negative pressure tube 15. The motor 17 is a servo motor 17, which can drive the support 12 to rotate, thereby driving the multiple adsorption chambers 18 on the support 12 to rotate and switch to communicate with the air duct 13 or the negative pressure tube 15. When the through holes on both sides of the adsorption chamber 18 correspond to the air duct 13, the pressurized gas is injected into the adsorption chamber 18 through the air duct 13. After the adsorption chamber 18 rotates to communicate with the negative pressure tube 15, it is extracted by the vacuum pump 14, so that the adsorption gas adsorbed on the molecular sieve is discharged. Carbon dioxide molecules spontaneously desorb at a lower pressure to complete the regeneration of the zeolite molecular sieve. Relying on the multiple adsorption chambers 18, when the motor 17 drives the support 12 to rotate, it drives the adsorption chamber 18 to switch to adsorption and desorption regeneration, thereby reducing the need for staff to stop and replace new adsorption modules, making it easier for staff to use. The zeolite molecular sieve module is composed of a whole piece of zeolite molecular sieve or multiple pieces of plate-shaped zeolite molecular sieves stacked together. The zeolite molecular sieve module is made of high-temperature adsorption material calcium oxide or low-temperature adsorption material zeolite molecular sieve;

[0040] When in use, heat exchange liquid flows in the heat pipe 23 to heat the heat pipe 23 and the heat conducting plate 22. When desorbing carbon dioxide, high-temperature heat exchange liquid is injected to heat the heat conducting plate 22. The zeolite molecular sieve plate 21 is a low-temperature adsorption material. Its adsorption capacity for carbon dioxide will decrease at high temperatures. The above-mentioned heating can facilitate the desorption of carbon dioxide. By means of heat transfer by the heat conducting plate 22, it can facilitate heat exchange in the adsorption chamber 18 with a lower air pressure caused by suction by the vacuum pump 14; when adsorbing carbon dioxide, low-temperature heat exchange liquid is injected to cool the heat conducting plate 22, so that the zeolite molecular sieve plate 21 can be quickly cooled, reducing the problem of cooling at the central position inside it, and keeping the zeolite molecular sieve plate 21 at a low temperature, so that the zeolite molecular sieve plate 21 can be easily For the adsorption of carbon dioxide, both the adsorption area and the desorption area of ​​the bin body 11 are equipped with heat exchange components, which rely on the cylinder 33 to drive the cross plate to move, so that the cannula 34 extends from the sliding hole on the bin body 11 and is inserted into the corresponding connecting seat 32, thereby connecting the cannula 34 and the connecting seat 32. The connecting seat 32 is connected to multiple heat-conducting pipes 23 through the connecting pipe 31 to transport heat exchange liquid. The heat exchange liquid pipeline is connected to the water pump, and the water pump transports the heated heat exchange liquid or the cooled heat exchange liquid to the cannula 34 connected to the heat exchange liquid pipeline. The cylinder 33 drives the cross plate to move the cannula 34, which drives the guide rod 82 to be inserted into the corresponding positioning hole 81, so as to fix the support 12, improve its stability, and improve the stability of the connection between the cannula 34 and the connecting seat 32;

[0041] During adsorption, the carbon dioxide is adsorbed after the airflow passes through the zeolite molecular sieve plate 21, and the uniformity of the airflow distribution will decrease. In this embodiment, the airflow passes through the zeolite molecular sieve plate 21 and enters the cavity 42 through the pores 41, then flows in the cavity 42, and then flows out through the pores 41 on the other side, thereby achieving a uniform distribution of the airflow. In addition, the airflow flowing in the cavity 42 can contact the heat pipe 23, thereby facilitating cooling of the airflow.

[0042] During use, since air will flow in the cavity 42, in order to facilitate the flow, the heat pipe 23 needs to be suspended in the cavity 42 or fixed by a porous bracket. However, after vacuuming, the cavity 42 loses gas to form heat convection to assist the heat exchange between the heat pipe 23 and the heat conducting plate 22, which will affect the temperature rise of the heat conducting plate 22. In this embodiment, when the heat conducting plate 22 is heated, the expanding liquid vaporizes, causing the rubber membrane 52 to expand and block the pores 41, thereby reducing the outflow of gas in the cavity 42 during vacuuming. This facilitates heat exchange between the heat pipe 23 and the heat conducting plate 22. The expansion liquid is one of ethyl acetate, methanol, and ethanol. During desorption, after the pores 41 are blocked, the heat conducting plate 22 will form a closed plate sandwiched between the zeolite molecular sieve plates 21, which will affect the discharge of carbon dioxide through the zeolite molecular sieve plates 21. In this embodiment, the middle part of the rubber membrane 52 is made of hard rubber material, and the expansion chambers 65 at both ends expand and fit with the side walls of the cavity 42, and pull the middle part of the rubber membrane 52 to open the middle part. , then the pore 41 is connected to the middle hole 63 in the middle of the rubber membrane 52, thereby sealing the cavity 42 and allowing the carbon dioxide to flow through. When the temperature drops, the rubber ring 62 can shrink the middle of the rubber membrane 52 to block the middle hole 63. The gap between the convex ring 73 and the exhaust seat is adapted to the thickness of the rubber membrane 52. The expansion cavity 65 at both ends of the rubber membrane 52 expands, which will pull the middle of the rubber membrane 52, so that the middle hole 63 in the middle of the rubber membrane 52 is connected. The rubber membrane 52 can be between the convex ring 73 and the exhaust seat. The air inlet seat 71 is provided with a conical structure, and the two ends of the rubber membrane 52 are sleeved on the surface of the air inlet seat 71. When in use, relying on the above arrangement, the two ends of the rubber membrane 52 can be easily expanded to block the air groove 72, thereby facilitating sealing.

[0043] When in use, the fixed arm 92 causes the sealing film 93 to bulge outward, and at the same time there is a certain gap between the sealing film 93 and the inner wall of the warehouse body 11. The support 12 does not fit with the inner wall of the warehouse body 11 when rotating, reducing the pressure on the sealing film 93. When the adsorption chamber 18 is under negative pressure, the pressure will cause the sealing film 93 to deform, and the fixed arm 92 will rotate to squeeze the sealing film 93 to fit with the inner wall of the warehouse body 11, thereby improving the sealing effect of the adsorption chamber 18.
