Description

Technical Field

[0001] The utility model relates to the field of air purification, in particular to an air purification device for a carbon capture enterprise. Background Art

[0002] Carbon dioxide is a greenhouse gas. With the current rise in global temperatures, the international community has gradually begun to control greenhouse gas emissions. Carbon capture companies are mainly committed to the research of carbon capture collection and storage. The main means of carbon capture include absorption, adsorption, membrane separation and oxygen-enriched combustion. Among them, carbon absorption is widely used as a low-cost and effective way to capture carbon. At present, air purification devices based on carbon absorption are mainly realized by water. For example, patent CN220346156U discloses an air purification device for a carbon capture industrial park, which mainly uses water to convectively spray the incoming air to the air to purify it. The purification effect of this method is general. Due to the rapid flow of air, the sprayed water cannot be fully and thoroughly in contact with the air, resulting in a decrease in the purification effect. There is also a carbon dioxide capture and purification mechanism in flue gas disclosed by patent CN220737044U, which is purified by alkaline solution absorption. However, we know that the chemical solution absorption method requires more requirements for the alkaline solution, such as non-toxicity and non-irritation. However, in most cases, although the chemical solution is non-toxic, it will have an odor. In order to achieve the purification effect of the air, some corresponding odor removal components must be equipped while capturing carbon. Obviously, this increases the complexity of the device and is not conducive to the simplified structural setting. Utility Model Content

[0003] Existing carbon capture air purification devices generally use water spraying or alkaline solution absorption. The water spraying method has a general purification effect. Due to the rapid flow of air, the sprayed water cannot fully and thoroughly contact the air, which leads to a general purification effect. The use of chemical solution absorption often makes the purified air have a pungent odor, which will put the cart before the horse. At least one aspect or one purpose of the present application can solve the above problems. Specifically, a carbon capture enterprise air purification device is designed, and the technical solution adopted is:

[0004] An air purification device for a carbon capture enterprise comprises a U-shaped box, wherein a partition is arranged inside the U-shaped box to separate it into a first box and a second box, wherein purified water is respectively stored in the first box and the second box, a heat exchange device is arranged at the bottom of the second box for reducing the temperature of the purified water in the second box, an air blowing device is arranged outside the U-shaped box, an air outlet of the air blowing device is connected to an air outlet pipe, the air outlet pipe extends into the first box and extends below the purified water level, an air outlet is arranged above the first box, the air outlet is connected to an air outlet pipe, the air outlet pipe extends into the second box and extends below the purified water level, and an air outlet is arranged above the second box.

[0005] Preferably, an air pressure opening and closing valve is connected to the air outlet pipe.

[0006] Preferably, the first box body and the second box body are commonly connected to a drain pipe, and the drain pipe is connected to a drain valve.

[0007] Preferably, an activated carbon filter is also provided in the second box, and the activated carbon filter is located above the level of the purified water.

[0008] Preferably, a filter is provided on the outside of the air outlet pipe corresponding to the U-shaped box.

DETAILED DESCRIPTION

[0014] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0015] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0016] like Figure 1-2 As shown, an air purification device for a carbon capture enterprise includes a U-shaped box 1, a partition 13 is provided inside the U-shaped box 1 to separate it into a first box 101 and a second box 102, the first box 101 and the second box 102 respectively store purified water 5, the water level of the purified water 5 is less than the height of the first box 101 and the second box 102, so that there is space for air to overflow above the first box 101 and the second box 102. In order to improve the effect of carbon dioxide purification and the solubility of carbon dioxide, a heat exchange device is provided at the bottom of the second box 102, which is mainly used to reduce the temperature of the purified water 5 in the second box 102, and a blast device 7 is provided outside the U-shaped box 1, and the air outlet of the blast device 7 is connected to an air outlet pipe 10, which extends into the first box 101 and extends below the liquid level of the purified water 5. It should be understood that the above-mentioned air outlet pipe 10 is a sealed connection at the connection with the first box 101, and is sealed by using existing sealing technology. The first box body 101 has an air outlet on the top, and the air outlet is connected to an air outlet pipe 8. The air outlet pipe 8 extends into the second box body 102 and extends below the liquid level of the purified water 5. The second box body 102 also has an air outlet 2 on the top.

[0017] External air enters the first box body 101, and the carbon dioxide in the air dissolves in the purified water 5 in the first box body 101, thereby achieving the purpose of primary carbon capture air purification. In addition, the gas that has undergone primary purification enters the second box body 102 again through the air outlet. Since the heat exchange device in the second box body 102 cools the water, the water temperature in the second box body 102 is lower than the water temperature in the first box body 101. Therefore, the water in the second box body 102 increases the solubility of carbon dioxide in the gas, and further performs carbon capture to achieve the purpose of secondary air purification. The two carbon capture air purifications improve the purification effect. At the same time, the purified water 5 for air purification will not be mixed with other odors, and there is no need to additionally configure a deodorization device, thereby reducing costs.

[0018] Furthermore, an air pressure opening and closing valve 9 is connected to the above-mentioned air outlet pipe 8. The air pressure opening and closing valve 9 can select air pressure opening and closing valves 9 of different pressures as needed. The setting of the air pressure opening and closing valve 9 can ensure that the gas in the first box body 101 can enter the second box body 102 through the air outlet pipe 8 only when it reaches a certain pressure, thereby increasing the solubility of carbon dioxide in the first box body 101 and improving the carbon capture air purification effect.

[0019] Furthermore, the purified water 5 in the first box 101 and the second box 102 will gradually become saturated due to the dissolution of carbon dioxide after being purified several times. Therefore, in order to replace the purified water 5 in the first box 101 and the second box 102 in time, the first box 101 and the second box 102 are commonly connected with a drain pipe 3, and the drain pipe 3 is connected with a drain valve 4. The drain valve 4 is opened when draining, and is closed during normal use.

[0020] Furthermore, in order to further purify larger particles in the air, an activated carbon filter 12 is further provided in the second box body 102 , and the activated carbon filter 12 is located above the liquid level of the purified water 5 .

[0021] Furthermore, a filter 11 is provided on the outside of the air outlet pipe 10 corresponding to the U-shaped box 1. The filter 11 has larger pores and can filter smoke particles in the air.

[0022] Furthermore, in order to increase the length of the heat exchange tube 6 in the second box 102 and improve the heat exchange efficiency, the heat exchange tube 6 of the above-mentioned heat exchange device is coiled in an S-shaped direction at the bottom of the second box 102, and the cooling medium in the heat exchange tube 6 can be input by an external fluid power pump.

[0023] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.

[0024] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
