For example, the reaction between gas and liquid is used to absorb certain components in the flue gas (such as carbon dioxide or sulfur dioxide), thereby purifying the flue gas, or the reaction between gas and liquid is used to cause carbon dioxide to precipitate from the liquid that absorbs carbon dioxide, thereby obtaining a high concentration of carbon dioxide gas for subsequent treatment of the carbon dioxide gas. These are all specific applications of gas-liquid reaction technology.

[0003] In the process of practical application, how to improve the reaction efficiency between gas and liquid is one of the important technical directions of gas-liquid reaction technology research. Utility Model Content

[0004] One purpose of the utility model is to provide a gas-liquid reaction device which can effectively improve the reaction efficiency of gas and liquid.

[0005] A further object of the present invention is to increase the degree of penetration of liquid into the packing member.

[0006] In particular, the utility model provides a gas-liquid reaction device, comprising:

[0007] A tower body, the tower body forming a reaction space; and

[0008] At least one reaction component is disposed in the reaction space, and each reaction component includes:

[0009] A packing member, wherein the packing member is formed with a structural region penetrating the packing member in the longitudinal direction, and the aperture of the structural region decreases from the top to the bottom; and

[0010] The spray head sprays toward the top of the tower body, and the spray head is located in the structural area so that the liquid sprayed by the spray head enters the structural area.

[0011] Optionally, the packing component includes a plurality of packing rings, which are arranged close to each other in the longitudinal direction, and the plurality of packing rings are arranged such that the diameters of the annular holes of the plurality of packing rings are smaller from top to bottom, so that the annular holes of the plurality of packing rings arranged in the longitudinal direction together constitute a construction area.

[0012] Optionally, among two adjacent packing rings, the top surface of the packing ring located at the bottom has a contact surface portion abutting against the bottom surface of the packing ring located at the top and a water receiving surface portion located inside the contact surface portion.

[0013] Optionally, the ratio of the radial width of the water contact surface portion to the thickness of the packing ring in which the water contact surface portion is located is greater than or equal to 0.5.

[0014] Optionally, the cross section of the spray head is circular, the spray head is provided with a plurality of spray holes, the plurality of spray holes are arranged around the central axis of the spray head, and the central axes of all the spray holes are located within the construction area.

[0015] Optionally, the radial widths of all water receiving surface portions are equal and the thicknesses of all packing rings are equal, and the central axis of the spray hole whose opening direction deviates most from the central axis of the spray head fits the upper edges of the annular holes of all packing rings.

[0016] Optionally, the shower head can rotate around its own central axis.

[0017] Optionally, the gas-liquid reaction equipment further comprises a water dispersion ring, which is arranged in the structural area, coaxially arranged with the spray head and located on the spray path of the spray head, so as to disperse the liquid sprayed from the spray head.

[0018] Optionally, each packing ring is formed by splicing together a plurality of sector ring parts.

[0019] Optionally, the gas-liquid reaction equipment includes a plurality of reaction components, and the plurality of reaction components are distributed in the reaction space along the longitudinal direction of the tower body.

[0020] The gas-liquid reaction device of the utility model is provided with a reaction assembly consisting of a packing member and a spray head forming a structural area in a tower body, the aperture of the structural area is set to be smaller and smaller from the top to the bottom, and the spray head is located in the structural area and sprayed toward the top of the tower body, so that the liquid sprayed by the spray head can diffuse in the structural area. During the operation of the gas-liquid reaction device, the gas to be treated is sent into the reaction space from the bottom of the tower body and flows from bottom to top in the reaction space. When flowing through the reaction assembly, part of the gas to be treated enters the structural area from the bottom of the structural area. Because the spray head continuously sprays the liquid for reacting with the gas to be treated into the structural area, the liquid and the gas to be treated react in the structural area, thereby absorbing the carbon dioxide in the gas to be treated. At the same time, because the aperture of the structural area becomes smaller and smaller from the top to the bottom, the gas can be said to flow through an increasingly wider channel as it flows upward along the structural area. Each time the gas passes through a point where the aperture changes, the gas flow rate slows down due to the wider channel. At the same time, the space in the structural area becomes larger, which helps to increase the reaction time of the gas and liquid, and also helps to increase the contact area between the gas and liquid, thereby effectively improving the reaction efficiency of the gas and liquid.

[0021] In addition, the liquid sprayed by the shower head can also fall on the filling component, so that the filling component is soaked with liquid for reacting with the gas to be treated, so that the gas flowing through the inside of the filling component can also react with the liquid soaked in the filling component, that is, the gas flowing through the reaction component from all places can react with the liquid. In addition, because the filling component is arranged around the shower head, the penetration effect of the liquid on the filling component is more uniform, so that the reaction effect of the filling component to the gas is more uniform.

[0022] Furthermore, the gas-liquid reaction device of the utility model arranges the packing member to be composed of a plurality of packing rings. On the one hand, because there are gaps between the packing rings, it is helpful for the liquid falling on the packing member to quickly penetrate along the gaps under the capillary action, thereby facilitating the penetration degree of the liquid in the packing member. On the other hand, when placing the packing member in the tower body, it can be placed one packing ring at a time, reducing the volume of the packing to be operated, making the packing placement work more convenient.

[0034] like Figures 1 to 3 As shown, in one embodiment, the gas-liquid reaction device 100 includes a tower body 110 and seven reaction assemblies 120. The tower body 110 is formed with a reaction space 111, and the seven reaction assemblies 120 are distributed in the reaction space 111 along the longitudinal direction of the tower body 110. Each reaction assembly 120 includes a packing member 121 and a spray head 122. The packing member 121 is formed with a structural area 1201 that penetrates itself in the longitudinal direction, and the aperture of the structural area 1201 becomes smaller and smaller from the top to the bottom. The spray head 122 sprays toward the top of the tower body 110, and the spray head 122 is located in the structural area 1201 so that the liquid sprayed by the spray head 122 enters the structural area 1201.

[0035] Reference Figures 1 to 3As shown, specifically, the reaction space 111 in the tower body 110 is a space for gas and liquid to react, and the reaction space 111 is cylindrical. Matchingly, the outer shape of the filler member 121 is cylindrical, so that the outer peripheral surface of the filler member 121 is adapted to the inner wall surface of the reaction space 111. The construction area 1201 can be regarded as a space obtained by hollowing out the cylinder from one end to the other end of the cylinder in the middle part of the cylinder. The aperture of the construction area 1201 is getting smaller and smaller from the top to the bottom, that is, the space size of the construction area 1201 is continuously limited from top to bottom. In other words, the complete construction area 1201 can be observed from the top to the bottom of the filler member 121 without being blocked.

[0036] Continue to refer to Figures 1 to 3 As shown, the setting position of the spray head 122 is located in the construction area 1201 and close to the bottom of the construction area 1201. The spray head 122 sprays upward, that is, the spray head 122 sprays from the bottom to the top of the construction area 1201, so that the liquid sprayed by the spray head 122 can be diffused in the construction area 1201.

[0037] Exemplarily, the gas-liquid reaction device 100 can be an absorption tower, which utilizes the reaction between gas and liquid to make the liquid absorb carbon dioxide in the gas to achieve carbon capture. Specifically, during the operation of the device, the gas to be treated is sent into the reaction space 111 from the bottom of the tower body 110, and flows upward along the reaction space 111. When flowing through the reaction assembly 120, part of the gas to be treated enters the structural area 1201 from the bottom of the structural area 1201. At the same time, the spray head 122 continuously sprays the liquid used to react with the gas to be treated into the structural area 1201, so that the liquid and the gas to be treated react in the structural area 1201, thereby absorbing the carbon dioxide in the gas to be treated. Because the aperture of the structural area 1201 becomes smaller and smaller from the top to the bottom, the gas flows through an increasingly wide channel in the process of flowing upward along the structural area 1201. Each time the aperture changes, the gas flow rate slows down due to the widening of the channel, thereby increasing the reaction time with the liquid. At the same time, the space becomes larger, and the reaction area with the liquid is increased.

[0038] In addition, the liquid sprayed by the shower head 122 can also fall onto the filling component 121, so that the filling component 121 is soaked with liquid for reacting with the gas to be treated. In this way, the gas flowing through the inside of the filling component 121 can also react with the liquid soaked in the filling component 121, that is, the gas flowing through the reaction component 120 from all places can react with the liquid.

[0039] In the scheme of the present embodiment, a reaction assembly 120 consisting of a filling member 121 and a spray head 122 forming a structural area 1201 is arranged in a tower body 110, the aperture of the structural area 1201 is set to become smaller and smaller from the top to the bottom, and the spray head 122 is located in the structural area 1201 and sprayed toward the top of the tower body 110, so that the liquid sprayed by the spray head 122 can diffuse in the structural area 1201. During the operation of the gas-liquid reaction equipment 100, the gas to be treated is sent into the reaction space 111 from the bottom of the tower body 110, and flows from bottom to top in the reaction space 111. When flowing through the reaction component 120, part of the gas to be treated enters the structural area 1201 from the bottom of the structural area 1201. Because the spray head 122 continuously sprays liquid for reacting with the gas to be treated into the structural area 1201, the liquid and the gas to be treated react in the structural area 1201, thereby absorbing the carbon dioxide in the gas to be treated.

[0040] At the same time, because the aperture of the structural area 1201 becomes smaller and smaller from the top to the bottom, the gas can be said to flow through an increasingly wider channel as it flows upward along the structural area 1201. Each time the gas passes through a point where the aperture changes, the gas flow rate slows down due to the wider channel. At the same time, the space of the structural area 1201 becomes larger, which helps to increase the reaction time of the gas and liquid, and also helps to increase the contact area between the gas and liquid, thereby effectively improving the reaction efficiency of the gas and liquid.

[0041] In addition, the liquid sprayed by the shower head 122 can also fall on the filling member 121, so that the filling member 121 is soaked with the liquid for reacting with the gas to be treated, so that the gas flowing through the inside of the filling member 121 can also react with the liquid soaked in the filling member 121, that is, the gas flowing through the reaction assembly 120 from all places can react with the liquid. In addition, because the filling member 121 is arranged around the shower head 122, the penetration effect of the liquid on the filling member 121 is more uniform, so that the reaction effect of the filling member 121 on the gas is more uniform.

[0042] It should be noted that, in some other embodiments, the number of reaction components may be one, two or more, and those skilled in the art may flexibly configure the number of reaction components according to the height of the tower body and the height of the reaction components.

[0043] like Figure 3 to Figure 4As shown, further, the packing component 121 includes a plurality of packing rings 1211, and the plurality of packing rings 1211 are arranged close to each other in the longitudinal direction, and the plurality of packing rings 1211 are arranged such that the aperture of the annular holes becomes smaller from top to bottom, so that the annular holes of the plurality of packing rings 1211 arranged in the longitudinal direction together constitute the construction area 1201.

[0044] Reference Figure 3 to Figure 4 As shown, in this embodiment, the packing member 121 includes four packing rings 1211, and the four packing rings 1211 are arranged in abutment with each other in the longitudinal direction, that is, for two adjacent packing rings 1211, the bottom surface of the upper packing ring 1211 abuts against the top surface of the lower packing ring 1211. The four packing rings 1211 have the same outer diameter, so that the outer peripheral surface formed after the four packing rings 1211 are stacked together is a cylindrical outer peripheral surface. The inner diameter of the packing ring 1211 is the aperture of its own ring hole. From top to bottom, the aperture of the ring hole of the packing ring 1211 becomes smaller and smaller, so that after the four packing rings 1211 are stacked together, the space formed by all the ring holes constitutes a longitudinal structural area 1201.

[0045] By configuring the packing member 121 to be composed of a plurality of packing rings 1211, on the one hand, because there are gaps between the packing rings 1211, it is helpful for the liquid falling on the packing member 121 to quickly penetrate along the gaps under the capillary action, thereby facilitating the penetration of the liquid into the packing member 121. On the other hand, when placing the packing member 121 into the tower body 110, the packing ring 1211 can be placed one at a time, thereby reducing the volume of the packing that needs to be operated at one time, making the packing placement work more convenient.

[0046] Continue to refer to Figure 3 and Figure 4 As shown, further, among the two adjacent packing rings 1211, the top surface of the packing ring 1211 located at the bottom has a contact surface portion that abuts against the bottom surface of the packing ring 1211 located at the top and a water receiving surface portion located inside the contact surface portion. And the annular holes of all packing rings 1211 are coaxially arranged. Specifically, the aperture of the annular hole of each packing ring 1211 itself is fixed, that is, the inner annular surface of each packing ring 1211 is a vertical surface, and the top surface and the bottom surface are annular surfaces of equal area.

[0047] Further, for two adjacent packing rings 1211, the aperture of the annular hole of the packing ring 1211 located below is smaller than the aperture of the annular hole of the packing ring 1211 located above, that is, the area of ​​the top surface of the packing ring 1211 located below is larger than the area of ​​the bottom surface of the packing ring 1211 located above, so that the complete annular hole of the packing ring 1211 located below and the partial top surface of the packing ring 1211 located below, that is, the water-receiving surface portion, can be observed from the top of the packing ring 1211 located above. Because the annular holes of all packing rings 1211 are coaxially arranged, for the packing ring 1211 located below, the contact surface portion and the water-receiving surface portion are both annular surfaces, and the contact surface portion is the same as the bottom surface of the packing ring 1211 located above, and the water-receiving surface portion is divided into the top surface of the packing ring 1211 located below minus the bottom surface of the packing ring 1211 located above. Or, in other words, the surface of the packing member 121 used to enclose the construction area 1201 is stepped.

[0048] It can be understood that by making the top surface of the packing ring 1211 located at the bottom of the two adjacent packing rings 1211 have a contact surface portion that is in contact with the bottom surface of the packing ring 1211 located at the top and a water receiving surface portion located inside the contact surface portion, that is, making the packing ring 1211 located at the bottom have a lateral surface that can receive the liquid sprayed by the spray head 122, the liquid receiving effect of the packing component 121 can be improved, thereby improving the penetration degree of the liquid in the packing component 121.

[0049] In addition, by arranging the annular holes of all the packing rings 1211 coaxially, the processing effect of the packing member 121 on the gas in the circumferential direction is made more uniform.

[0050] It should be noted that, in some other embodiments, the annular hole of each packing ring may not have a fixed aperture, but may be an annular hole with a gradually decreasing aperture. In this case, of two adjacent packing rings, the aperture at the top surface of the packing ring located at the bottom may be equal to the aperture at the bottom surface of the packing ring located at the top, so that the spatial shape of the entire structural area is truncated cone-shaped. Alternatively, the aperture at the top surface of the packing ring located at the bottom may be smaller than the aperture at the bottom surface of the packing ring located at the top.

[0051] In addition, it should be noted that, in some other embodiments, the annular holes of each packing ring may also be arranged in a non-coaxial manner, and a water-connecting surface portion may also be formed.

[0052] It should be noted that, in some other embodiments, the number of packing rings of the packing component may also be two, three, five or more.

[0053] Reference Figure 3As shown, further, the ratio of the radial width of the water-contacting surface portion to the thickness of the packing ring 1211 in which it is located is greater than or equal to 0.5. Specifically, the radial width of the water-contacting surface portion is the dimension in the direction of the center of the packing ring 1211. Figure 3 Taking the second packing ring 1211 from top to bottom as an example, the radial width of the water-receiving surface portion is D, and the thickness of the packing ring 1211 is H, that is, D / H is greater than or equal to 0.5, for example, it can be 0.5, 0.7, 1, 1.5 or 2, so as to help ensure the penetration effect of the liquid on the packing ring 1211. Preferably, the ratio of the radial width of the water-receiving surface portion to the thickness of the packing ring 1211 where it is located is greater than or equal to 1 and less than or equal to 2.

[0054] like Figure 3 As shown, further, the cross section of the spray head 122 is circular, and the spray head 122 is provided with a plurality of spray holes, and the plurality of spray holes are arranged around the central axis of the spray head 122, and the central axis of all the spray holes is located within the structural area 1201. Specifically, the cross section of the spray head 122 is the cross section after being cut off by the transverse surface, and the central axis of the spray head 122 is the longitudinal line passing through the center of the circle of its cross section. Among them, the spray head 122 can be a truncated cone, and the plurality of spray holes are distributed in multiple circles along the longitudinal direction of the spray head 122, and each circle of spray holes is arranged around the central axis of the spray head 122. Alternatively, the spray head 122 can also be a disc-shaped, and the plurality of spray holes are distributed on the transverse top surface of the spray head 122, and the plurality of spray holes are distributed in multiple circles along the circumference of the spray head 122, and each circle of spray holes is arranged around the central axis of the spray head 122.

[0055] Furthermore, the central axis of the spray hole, that is, the straight line passing through the center of the opening of the spray hole and extending along the opening direction of the spray hole, the central axis of all the spray holes is located in the structural area 1201, that is, the central axis of all the spray holes will not pass through the solid part of the filling component 121. This helps to prevent the liquid sprayed by the spray head 122 from being blocked by the filling component 121, thereby helping to improve the utilization rate of the spray holes and reduce design redundancy on the basis of allowing the liquid sprayed by the spray head 122 to more fully cover the structural area 1201.

[0056] Reference Figure 3 As shown, further, the radial widths of all water-receiving surface parts are equal and the thicknesses of all packing rings 1211 are equal, and the central axis of the spray hole whose opening direction deviates most from the central axis of the spray head 122 fits the upper edges of the ring holes of all packing rings 1211. Specifically, that is, the water-receiving surface widths of the second packing ring 1211, the third packing ring 1211, and the fourth packing ring 1211 from top to bottom are equal, and the thicknesses of the four packing rings 1211 are equal. The spray hole whose opening direction deviates most from the spray head 122 is also the spray hole whose tilt direction deviates most from the spray head 122. Figure 3 As shown in the figure, the two inclined straight lines, i.e., the central axes of the two spray holes whose opening directions are most deviated from the central axis of the spray head 122, are schematic diagrams. Since the radial widths of all water-connecting surface parts are equal and the thicknesses of all packing rings 1211 are equal, a straight line can simultaneously fit the upper edges of the annular holes of all packing rings 1211, that is, the edges of the annular holes of all packing rings 1211 on the top surfaces of the packing rings 1211, and then the upper edges of the annular holes of all packing rings 1211 whose opening directions are most deviated from the central axis of the spray head 122 can be fit.

[0057] The above structure is advantageous in that the spraying range of the spray head 122 can more fully cover the entire structural area 1201 , thereby helping to further improve the reaction efficiency of the liquid and gas in the structural area 1201 .

[0058] Reference Figure 3 As shown, further, the spray head 122 can rotate around its own central axis, so that the spray head 122 can rotate during the spraying process so that the sprayed liquid can more effectively cover the entire construction area 1201, and help to enhance the turbulent mixing effect of the liquid and the gas, thereby helping to further improve the reaction efficiency of the liquid and the gas in the construction area 1201.

[0059] like Figure 4 and Figure 5 As shown, further, each packing ring 1211 is composed of a plurality of fan ring parts 1212. Specifically, the plurality of fan ring parts 1212 can be regarded as structures obtained by cutting the packing ring 1211 along different radial directions. Figure 5 As shown, taking a packing ring 1211 as an example, it is composed of four sector ring parts 1212.

[0060] By making each packing ring 1211 composed of a plurality of fan-shaped parts 1212, on one hand, each packing ring 1211 can have a gap, which helps the liquid falling on the packing ring 1211 to quickly penetrate along the gap under the capillary action, thereby further improving the penetration degree of the liquid in the packing member 121. On the other hand, when placing the packing member 121 in the tower body 110, it can be placed in a manner of placing one fan-shaped part 1212 of a packing ring 1211 at a time, further reducing the volume of the packing required to be operated at one time, making the packing placement work more convenient.

[0061] It should be noted that the number of sector ring parts of each packing ring may be different or the same.

[0062] like Figure 6As shown, in one embodiment, the gas-liquid reaction device further includes a water dispersion ring 130, which is disposed in the structural area 1201. The water dispersion ring 130 is coaxially disposed with the spray head 122 and is located on the spray path of the spray head 122, so as to disperse the liquid sprayed by the spray head 122. Specifically, the water dispersion ring 130 is a circular ring structure. When the spray head 122 sprays the liquid, the liquid sprayed by the spray head 122 can hit the water dispersion ring 130, thereby having a dispersion effect on the liquid, so that the liquid is dispersed into smaller droplets, and the flight direction of the droplets is also more divergent, which can improve the reaction efficiency of the liquid and the gas on the one hand, and also help to make the liquid more evenly scattered on the filler component 121 on the other hand.

[0063] It should be noted that the water dispersion ring can be fixed to the sprinkler head via a connecting rod, or can also be fixed to the tower body via a connecting rod.

[0064] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
