Description

Technical Field

[0001] The utility model relates to the technical field of carbon dioxide adsorption, in particular to a carbon dioxide capture and recovery system. Background Art

[0002] Carbon neutrality and carbon peak are important measures to address global climate change, and are of great significance for protecting the ecological environment and promoting green development.

[0003] In industries such as petroleum, coking, metal smelting, electric power and heat, there is a large amount of industrial waste heat in the form of waste water, waste gas, etc. This waste heat cannot be utilized, thus wasting energy.

[0004] A carbon dioxide ion exchange resin with a carbon dioxide adsorption rate at low temperature greater than that at high temperature can fully solve the problem of existing industrial waste heat in the above industries. However, large-scale carbon dioxide ion exchange resin is required to efficiently adsorb carbon dioxide. Therefore, the adsorption device is often very large in volume, which increases the difficulty of building the adsorption device. Utility Model Content

[0005] The purpose of the utility model is to provide an assembled carbon dioxide adsorption module to solve at least one of the above technical problems.

[0006] The technical problem solved by the present invention can be achieved by adopting the following technical solutions:

[0007] The assembled carbon dioxide adsorption module includes a carbon dioxide ion exchange resin capable of adsorbing carbon dioxide, and is characterized in that it also includes an exchange chamber, wherein the exchange chamber has an airtight shell;

[0008] The shell is provided with an air inlet and an air outlet;

[0009] The exchange chamber is filled with carbon dioxide ion exchange resin;

[0010] The air inlet has a connection mechanism, and the air outlet has another connection mechanism;

[0011] One connecting mechanism and another connecting mechanism adopt a connection matching structure;

[0012] A carrying device is also provided at the air outlet, and a filtering mechanism is provided on the carrying device;

[0013] A heat exchange device is also arranged in the exchange chamber.

[0014] The utility model discloses a unit module capable of realizing carbon dioxide adsorption. A plurality of unit modules can be assembled together to realize more efficient carbon dioxide adsorption.

[0015] The utility model includes an exchange chamber, the shell of the exchange chamber includes an air inlet and an air outlet, a connecting mechanism is arranged at the air inlet, and another connecting mechanism is arranged at the air outlet, and the two connecting mechanisms are mechanisms that can be connected to each other. Through this design, the air outlets and air inlets of the two exchange chambers can be connected to each other to form a new airtight airflow channel. After the exchange chambers are connected to each other, more carbon dioxide ion exchange resins are added, and the adsorption capacity of carbon dioxide becomes stronger.

[0016] A carrying device is arranged at the gas outlet to prevent the carbon dioxide ion exchange resin from leaking out of the exchange chamber, and a filtering mechanism is arranged on the carrying device to clean the carbon dioxide ion exchange resin.

[0017] In the utility model, the carbon dioxide ion exchange resin adopts a cross-linked polystyrene type primary amine type carbon dioxide ion exchange resin.

[0018] Cross-linked polystyrene primary amine carbon dioxide ion exchange resin is a new type of carbon dioxide ion exchange resin with the ability to adsorb carbon dioxide gas in recent years. One cubic cross-linked polystyrene primary amine carbon dioxide ion exchange resin can adsorb 29kg of carbon dioxide. The cross-linked polystyrene primary amine carbon dioxide ion exchange resin can be in micro-granular or powder form and has a large surface area, which is conducive to the adsorption of carbon dioxide gas.

[0019] The recovery of carbon dioxide by carbon dioxide ion exchange resin is divided into two stages: the first stage is the adsorption stage, when air is introduced into the exchange chamber and the carbon dioxide ion exchange resin adsorbs carbon dioxide gas; the second stage is the release stage, when the exchange chamber is closed to form an enclosed space, the heat exchange device heats up, and drives the temperature in the exchange chamber to rise, at which time the carbon dioxide ion exchange resin releases the previously adsorbed carbon dioxide gas.

[0020] Furthermore, the shell is made of metal.

[0021] In this design, hot water or hot air is introduced outside the exchange chamber. The shell is made of metal material and has a heat-conducting function, which can increase the temperature in the exchange chamber, and then the carbon dioxide ion exchange resin releases the adsorbed carbon dioxide gas under high temperature conditions.

[0022] For further optimization, the heat exchange device adopts heat exchange plates; the heat exchange plates are fixed on the inner wall of the shell.

[0023] In this design, a heat exchange plate is further arranged in the shell. Through the thermal conductivity of the heat exchange plate, heat can be introduced from the shell into the exchange chamber, thereby accelerating the temperature rise in the exchange chamber, and then the carbon dioxide ion exchange resin releases the adsorbed carbon dioxide gas under high temperature conditions.

[0024] For further optimization, the heat exchange device uses metal strips arranged in a staggered manner; the metal strips are fixed to the inner wall of the shell.

[0025] This design is another heat conduction solution that uses metal strips with heat conduction properties to conduct heat from the shell to the inside of the exchange chamber, accelerate the temperature rise in the exchange chamber, and then the carbon dioxide ion exchange resin releases the adsorbed carbon dioxide gas under high temperature conditions.

[0026] Furthermore, the heat exchange device adopts a heat exchange pipe, and the heat exchange pipe includes an inlet and an outlet.

[0027] This design is another solution for raising the temperature in the exchange chamber. There is no need to introduce hot water or hot air outside the exchange chamber. Instead, a heat exchange pipe is set inside the exchange chamber. Hot water or hot air is introduced into the heat exchange pipe to increase the temperature in the exchange chamber. Under high temperature conditions, the carbon dioxide ion exchange resin releases the adsorbed carbon dioxide gas.

[0028] In a further optimization, the inlet has a docking mechanism, and the outlet has another docking mechanism; one docking mechanism and the other docking mechanism adopt a docking matching structure.

[0029] In the utility model, after one exchange chamber is connected to another exchange chamber, the design can allow the heat exchange pipes in the two exchange chambers to be connected in series through a docking mechanism. An external heat source is connected to the heat exchange pipe of one of the exchange chambers and can flow in the heat exchange pipes in the other exchange chambers. The beneficial effect is that the cost and complexity of connecting the heat exchange pipes are reduced.

[0030] Furthermore, another carrying device is arranged at the air inlet, and a filtering mechanism is arranged on the other carrying device.

[0031] This design is suitable for the horizontal setting scenario of the utility model. When the exchange chamber is set horizontally, it is necessary to set a bearing device at both the air inlet and the air outlet to intercept the loss of carbon dioxide ion exchange resin in the exchange chamber.

[0032] For further optimization, a non-woven filter layer is provided between the carbon dioxide ion exchange resin and the supporting device.

[0033] In the utility model, the carbon dioxide ion exchange resin adopts cross-linked polystyrene type primary amine type ion exchange resin, and the cross-linked polystyrene type primary amine type ion exchange resin adopts one of granular or powdery micro-particles.

[0034] In this design, a non-woven fabric filter layer is provided between the carbon dioxide ion exchange resin and the supporting device to further enhance the protection against the loss of the carbon dioxide ion exchange resin, especially when the carbon dioxide ion exchange resin is in the form of powdery tiny particles. The carbon dioxide ion exchange resin in the form of powdery tiny particles cannot be effectively intercepted from being lost by the supporting device alone.

[0035] Furthermore, the connection mechanism is a flange connection mechanism.

[0036] The flange connection mechanism is provided with a sealing ring on the connection end face. After being fixed by bolts, the gas outlet of one exchange chamber is sealed and connected to the gas inlet of another exchange chamber to form an airtight gas path. When the carbon dioxide ion exchange resin releases carbon dioxide, the airtight gas path can prevent the carbon dioxide gas from escaping.

[0037] Furthermore, the cross section of the exchange chamber is circular, the circumference is 300 to 1250 cm, and the height is 30 to 100 cm.

[0038] The exchange chamber adopts a circular shape, which has the largest volume under the same material, and the circular shape is also conducive to air circulation. If the volume of the exchange chamber is too large, it will be inconvenient for transportation and installation; if the volume of the exchange chamber is too small, the adsorption and release efficiency will be too low. Therefore, an appropriate size is required to reduce the cost of manufacturing, transportation, installation, etc. while ensuring high efficiency of carbon dioxide adsorption and release.

[0039] The utility model adopts a modular approach to design an assemblable carbon dioxide adsorption device, in which carbon dioxide ion exchange resin is filled, and a heat exchange device is also provided. The heat exchange device is used to heat the adsorption device, and the carbon dioxide ion exchange resin has different carbon dioxide gas adsorption rates at low and high temperatures, thereby achieving the purpose of carbon dioxide gas adsorption and release recovery.

[0040] Its beneficial effect also lies in that heating can utilize waste heat, waste water or waste heat and waste gas within the industry, reduce energy waste, and achieve the social goal of reducing emissions and increasing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

A connecting mechanism is arranged at the air inlet, and another connecting mechanism is arranged at the air outlet. The two connecting mechanisms are mechanisms that can be connected to each other. Through this design, the air outlet and the air inlet of the two exchange chambers can be connected to each other to form a new airtight airflow channel. After the exchange chambers are connected to each other, more carbon dioxide ion exchange resins are added, and the adsorption capacity of carbon dioxide becomes stronger.

[0059] The air outlet is provided with a carrier device 7 to prevent the carbon dioxide ion exchange resin from leaking out of the exchange chamber. The carrier device 7 is provided with a filtering mechanism for cleaning the carbon dioxide ion exchange resin.

[0060] In this embodiment, the carbon dioxide ion exchange resin is a cross-linked polystyrene primary amine carbon dioxide ion exchange resin.

[0061] Cross-linked polystyrene primary amine carbon dioxide ion exchange resin is a new type of carbon dioxide ion exchange resin with the ability to adsorb carbon dioxide gas in recent years. One cubic cross-linked polystyrene primary amine carbon dioxide ion exchange resin can adsorb 29kg of carbon dioxide. The cross-linked polystyrene primary amine carbon dioxide ion exchange resin can be in micro-granular or powder form and has a large surface area, which is conducive to the adsorption of carbon dioxide gas.

[0062] The recovery of carbon dioxide by carbon dioxide ion exchange resin is divided into two stages: the first stage is the adsorption stage, when air is introduced into the exchange chamber and the carbon dioxide ion exchange resin adsorbs carbon dioxide gas; the second stage is the release stage, when the exchange chamber is closed to form an enclosed space, the heat exchange device heats up, and drives the temperature in the exchange chamber to rise, at which time the carbon dioxide ion exchange resin releases the previously adsorbed carbon dioxide gas.

[0070] The heat exchange device uses staggered metal strips; the metal strips are fixed on the inner wall of the shell 1.

[0071] This embodiment is another heat conduction solution, which uses a metal strip with heat conduction properties to conduct heat from the shell 1 to the inside of the exchange chamber, accelerate the temperature rise in the exchange chamber, and then the carbon dioxide ion exchange resin releases the adsorbed carbon dioxide gas under high temperature conditions.

[0072] Embodiment 4: The heat exchange device adopts a heat exchange pipe 4 , and the heat exchange pipe 4 includes an inlet 5 and an outlet 6 .

[0073] This embodiment is another solution for increasing the temperature in the exchange chamber. There is no need to introduce hot water or hot air outside the exchange chamber. Instead, a heat exchange pipe 4 is provided inside the exchange chamber. Hot water or hot air is introduced into the heat exchange pipe 4 to increase the temperature in the exchange chamber. Under high temperature conditions, the carbon dioxide ion exchange resin releases the adsorbed carbon dioxide gas.

[0074] The inlet 5 has a docking mechanism, and the outlet 6 has another docking mechanism; one docking mechanism and the other docking mechanism adopt a docking matching structure.

[0075] In this embodiment, after one exchange chamber is connected to another exchange chamber, this design allows the heat exchange pipes 4 in the two exchange chambers to be connected in series through a docking mechanism.
