[0002] In related technologies, fixed-bed adsorption towers and moving-bed adsorption towers are commonly used to purify flue gas through adsorption. However, both fixed-bed and moving-bed adsorption towers are inconvenient and time-consuming to replace the packing material.

This dust is then discharged with the flue gas, failing to meet purification requirements. Summary of the Invention

Detailed Implementation

[0022] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] like Figure 1-4 As shown, the drawer-type material changing adsorption device 100 of this embodiment includes a cylinder 110, a drawer component 120 and a plurality of adsorption cylinders 130.

[0024] The cylinder 110 defines a cavity, and the cylinder 110 is provided with a flue gas inlet 113 and a flue gas outlet 114. A material replacement window 1101 is opened on the side wall of the cylinder 110.

[0025] The drawer component 120 can be pulled out of the cylinder 110 and pushed into the cylinder 110 through the material changing window 1101.

[0026] The adsorption cylinder 130 is filled with adsorbent and is detachably mounted on the drawer assembly 120. The adsorption cylinder 130 has an air inlet 133 and an air outlet 134. The drawer assembly 120 and the adsorption cylinder 130 isolate the cavity inside the cylinder body 110 into an air inlet cavity 111 and a clean air cavity 112. It is understood that when the drawer assembly 120 pushes the adsorption cylinder 130 into the cylinder body 110, there must be no air leakage between the air inlet cavity 111 and the clean air cavity 112 to prevent the flue gas that has not been adsorbed and purified by the adsorption cylinder 130 from leaking from the air inlet cavity 111 into the clean air cavity 112. The air inlet cavity 111 is connected to the flue gas inlet 113, and the clean air cavity 112 is connected to the flue gas outlet 114.

[0027] When the drawer-type material-changing adsorption device 100 of this embodiment is working, the flue gas enters the air inlet chamber 111 from the flue gas inlet 113 and enters the adsorption cylinder 130 from the air inlet 133. During the flow of the flue gas to the air outlet 134, it comes into contact with the adsorbent in the adsorption cylinder 130. The adsorbent adsorbs and purifies the flue gas. The clean flue gas enters the clean air chamber 112 from the air outlet 134 of the adsorption cylinder 130 and is finally discharged through the flue gas outlet 114.

[0028] The drawer-type adsorption device of the present invention allows for the replacement of the adsorbent by pulling out and pushing the adsorption cylinder through the drawer component 120 when the adsorbent needs to be replaced. The adsorbent replacement is unitized and modularized, making adsorbent replacement more convenient and faster. No loading and unloading operations are required, which reduces friction and collision between adsorbent particles, reduces dust generation and adsorbent loss, and the adsorption cylinder has a simple structure and low manufacturing cost.

[0029] In some embodiments, the outer peripheral wall of the adsorption cylinder 130 is provided with an outwardly protruding limiting portion 132, and the drawer component 120 is provided with an opening groove 121. The adsorption cylinder 130 can be pushed into and pulled out of the opening groove 121 through the opening. The limiting portion 132 abuts against the drawer component 120 to suspend and fix the adsorption cylinder 130 on the drawer component 120. It is understood that when the adsorption cylinder 130 is positioned in the drawer component 120, the adsorption cylinder 130 and the drawer component 120 are airtightly connected to avoid air leakage.

[0030] For example, the adsorption cylinder 130 includes a straight cylindrical portion 131 and a limiting portion 132 connected to the top of the straight cylindrical portion 131. The limiting portion 132 can be an integrally formed flange. A plurality of straight cylindrical portions 131 of the adsorption cylinders 130 are correspondingly disposed in the opening groove 121. The width of the limiting portion 132 is greater than the width of the opening groove 121, such that the lower surface of the limiting portion 132 abuts against the upper surface of the drawer component 120 near the opening groove 121, thus hanging the adsorption cylinder 130 on the drawer component. When it is necessary to replace the adsorption cylinder 130, the limiting portion 132 can slide along the opening groove 121, thereby facilitating the disassembly and assembly of the adsorption cylinder 130.

[0031] Optionally, the cylindrical portion 131 may have a rectangular, square, or circular cross-section, or other cross-section shapes.

[0032] In some embodiments, the drawer component 120 is provided with a plurality of opening slots 121. Optionally, the opening slot 121 is an elongated hole that passes through the drawer component 120 in the vertical direction and is closed at one end and open at the other end.

[0033] The adsorption device 100 with drawer-type material replacement provided in this embodiment of the invention is filled with adsorbent in several adsorption cylinders 130. The adsorption cylinders 130 are supported and fixed in the cylinder body 110 by a drawer component 120. The drawer component 120 can enter and exit the cavity through the material replacement window 1101. When replacing the adsorbent that has been saturated with adsorption, the material replacement window 1101 is opened, the drawer component 120 is pulled out, and the adsorption cylinders 130 are removed from the drawer component 120 one by one. The adsorption cylinders 130 filled with new adsorbent are then pushed into the cavity.

[0034] Therefore, the unitized and modular design of the adsorbent replacement system makes the replacement process more convenient and faster, eliminating the need for loading and unloading operations, reducing friction and collision between adsorbent particles, and minimizing dust generation and adsorbent loss. Furthermore, the simple structure of the replacement mechanism and adsorption cylinder results in low manufacturing costs, making it particularly suitable for flue gas adsorption in small-scale equipment, or for the adsorption of small quantities of flue gas, as well as for the deep removal of clean gas.

[0035] In some embodiments, such as Figure 2 As shown, multiple adsorption cylinders 130 can be installed in each opening slot 121, and the spacing between the adsorption cylinders 130 is adjustable. For example, multiple adsorption cylinders 130 can be installed in one opening slot 121, and the spacing between two adjacent adsorption cylinders 130 can be adjusted. Thus, the number of adsorption cylinders 130 in each opening slot 121 can be flexibly set by adjusting the spacing between the adsorption cylinders 130 to meet different purification needs.

[0036] In some embodiments, such as Figure 2 As shown, the drawer-type material changing adsorption device 100 includes several sealing blocks 150. The sealing blocks 150 are detachably installed on the drawer component 120 and can slide along the opening groove 121. The sealing blocks 150 are located on the opening groove 121 between two adjacent adsorption cylinders 130 and are sealed to the adsorption cylinders 130 to prevent flue gas from leaking from the opening groove 121 between the air inlet chamber and the clean air chamber.

[0037] For example, a sealing block 150 is provided between two adjacent adsorption cylinders 130. The structure of the connection between the sealing block 150 and the adsorption cylinder 130 can be adapted to the surface of the adsorption cylinder 130 so as to seal the connection with the adsorption cylinder 130, thereby preventing flue gas from leaking between the adsorption cylinder 130 and the sealing block 150. The sealing block 150 is detachably connected to the opening groove 121. For example, the sealing block 150 can move along the opening groove 121.

[0038] Optionally, there may be multiple sealing blocks 150 and various lengths of sealing blocks 150, so that the spacing between two adjacent adsorption cylinders 130 can be adjusted by using sealing blocks 150, thereby facilitating the adjustment of the number of adsorption cylinders 130.

[0039] In some embodiments, such as Figure 4 As shown, the cylinder 110 is provided with a slide rail 1102, and the drawer component 120 is supported on the slide rail 1102 and slides into and out of the cylinder 110 through the material changing window 1101 along the slide rail 1102.

[0040] like Figure 3As shown, the inner wall of the cylinder 110 is provided with inwardly protruding and opposite support parts 1103, the upper surface of the slide rail 1102 is provided with a slide groove 1104, and the drawer component 120 is provided with sliding parts 122 on both sides. The two sliding parts 122 are matched one-to-one in the two slide grooves 1104 and can slide relative to the slide grooves 1104.

[0041] For example, a support portion 1103 is provided on the inner wall surface of the cylinder 110. The support portion 1103 protrudes inward from the inner wall surface of the cylinder 110. A groove 1104 is provided on the surface of the support portion 1103. Two oppositely arranged sliding members 122 are provided on the drawer component 120. The two sliding members 122 are slidably engaged in the two grooves 1104 respectively. Thus, the grooves 1104 and the sliding members 122 can facilitate the drawer component 120 to enter and exit the cylinder 110 through the material changing window 1101, thereby facilitating the replacement of the adsorption cylinder 130.

[0042] Optionally, the slider 122 is provided at the bottom of the drawer component 120, so that the upper surface of the support 1103 can abut against the lower surface of the drawer component 120 to support the drawer component 120.

[0043] The slider 122 fits into the slide groove 1104, thereby better positioning the drawer component 120 within the cylinder 110.

[0044] In some embodiments, the drawer component 120 can swing up and down in the pulled-out position of the pulled-out cylinder 110 to adjust the inclination of the opening slot 121, thereby making it easier to slide the adsorption cylinder 130 out of the opening slot 121 by gravity, further improving convenience.

[0045] In some embodiments, such as Figure 4 As shown, the drawer component 120 includes a pivot, and the slide rail 1102 has a locking groove 11021 adjacent to the material changing window 1101. When the drawer component 120 is pulled out to the pulled-out position, the pivot falls into and engages in the locking groove 11021 and can rotate relative to the locking groove 11021, thereby allowing the drawer component 120 to swing relative to the cylinder 110, which facilitates the replacement of the suction cylinder 130. Optionally, the drawer component 120 also has a handle 123 to allow the operator to push and pull the drawer component 120.

[0046] The flue gas treatment system of this invention includes the drawer-type refrigerant adsorption device 100 and the cooling module 140 described in the above embodiments. The cooling module 140 is used to cool the flue gas to be adsorbed supplied to the cylinder 110 to room temperature or below, so as to perform low-temperature adsorption purification and thereby improve the flue gas purification effect. Figure 1 As shown, the cooling module 14 is integrated into the cylinder 110, which can reduce the number of devices and the floor space occupied by the flue gas treatment system, thereby improving the integration of the equipment.

[0047] The flue gas treatment system of this invention has the advantages of convenient adsorbent replacement and high equipment integration.

[0048] The following is based on Figures 1-4 The adsorption device 110 and the flue gas treatment system having the present invention are described in specific embodiments.

[0049] like Figure 1 and Figure 2 As shown, the drawer-type material changing adsorption device 100 of this embodiment includes a cylinder 110, a drawer component 120 and a plurality of adsorption cylinders 130.

[0050] The cylinder 110 has a hollow structure defining a cavity. The drawer component 120 can enter and exit the cavity through the material changing window 1101. The cavity of the cylinder 110 is divided into an air inlet cavity 111 and a clean air cavity 112. The cylinder 110 is provided with a flue gas inlet 113 and a flue gas outlet 114. The flue gas inlet 113 is connected to the air inlet cavity 111, and the flue gas outlet 114 is connected to the clean air cavity 112.

[0051] During operation, flue gas enters the intake chamber 111 from the flue gas inlet 113 and enters the adsorption cylinder 130 from the intake port 133. As the flue gas flows toward the outlet 134, it comes into contact with the adsorbent in the adsorption cylinder 130. The adsorbent adsorbs and purifies the flue gas. The clean flue gas enters the clean gas chamber 112 from the outlet 134 of the adsorption cylinder 130 and is finally discharged through the flue gas outlet 114.

[0052] In the drawer-type adsorption device 100 of this invention, the adsorbent is filled in a plurality of adsorption cylinders 130. The adsorption cylinders 130 are supported and fixed in the cylinder body 110 by a drawer component 120. The drawer component 120 can enter and exit the cylinder body 110 through the material replacement window 1101. When it is necessary to replace the adsorbent that has been saturated, the material replacement window 1101 is opened, the drawer component 120 is pulled out, the adsorption cylinder 130 is removed from the drawer component 120 as a whole, and then an adsorption cylinder 130 filled with new adsorbent is put in and then pushed into the cylinder body 110. Then the material replacement window 1101 is closed.

[0053] The adsorption cylinder 130 includes a straight cylindrical portion 131 and a limiting portion 132 provided on the top of the straight cylindrical portion 131. The straight cylindrical portions 131 of a plurality of adsorption cylinders 130 are provided in the opening groove 121 in a one-to-one correspondence. The width or radial dimension of the limiting portion 132 is greater than the width of the opening groove 121, such that the lower surface of the limiting portion 132 abuts against the upper surface of the drawer component 120 near the opening groove 121 so that the adsorption cylinder 130 is hung on the drawer component.

[0054] Multiple adsorption cylinders 130 are installed in an open slot 121. The distance between two adjacent adsorption cylinders 130 can be adjusted by a sealing block 150. The structure of the sealing block 150 at the connection with the adsorption cylinder 130 can be adapted to the surface of the adsorption cylinder 130 so as to seal the connection with the adsorption cylinder 130.

[0055] A support portion 1103 is provided on the inner wall surface of the cylinder 110. The support portion 1103 protrudes inward from the inner wall surface of the cylinder 110 and is provided with a sliding groove 1104. The drawer component 120 is provided with two oppositely arranged sliding members 122. The two sliding members 122 are slidably engaged in the two sliding grooves 1104 respectively. Thus, the sliding grooves 1104 and the sliding members 122 can facilitate the drawer component 120 to enter and exit the material changing window 1101, thereby facilitating the replacement of the adsorption cylinder 130 and making the replacement of the adsorption cylinder 130 convenient and quick.

[0056] The cooling module 140 is a spray cooling module 140 and is located in the lower part of the cylinder 110. The spray cooling module 140 includes a packing layer 141 and a coolant spraying assembly 142. The coolant spraying assembly 142 sprays coolant onto the packing layer 141. In the packing layer 141, the coolant directly contacts the flue gas for heat exchange and cools the flue gas. The coolant flows out from the coolant outlet 143 on the bottom wall.

[0057] In another embodiment of the flue gas adsorption device of the present invention, a slide rail 1102 is provided on the inner side of the cylinder 110, and a drawer component 120 cooperates with the slide rail 1102 and is slidably arranged along the slide rail 1102. For example, the drawer component 120 is provided with a pulley, which is mounted on the slide rail 1102 so that the drawer component 120 can move on the slide rail 1102, thereby realizing the entry and exit of the material replacement window 1101, and thus facilitating the replacement of the adsorption cylinder 130.

[0058] The drawer component 120 includes a pivot, and the slide rail 1102 is provided with a locking groove 11021. When the drawer component 120 is pulled out, the pivot enters and engages in the locking groove 11021 and can rotate relative to the locking groove 11021, thereby causing the drawer component 120 to swing relative to the cylinder 110, which facilitates the replacement of the suction cylinder 130.

[0059] The drawer component 120 has an inner end and an outer end. The outer end of the drawer component 120 is the end adjacent to the material changing window 1101, and the inner end of the drawer component 120 is the end away from the material changing window 1101. The drawer component 120 can swing. When it is necessary to disassemble the adsorption cylinder 130, the drawer component 120 is tilted downward relative to the material changing window 1101, so that the adsorption cylinder 130 can slide along the opening groove 121 to the outer end of the opening groove 121, thereby facilitating the removal of the adsorption cylinder 130 by the operator. When installing the adsorption cylinder 130, the drawer component 120 is tilted upward relative to the material changing window 1101, so that the adsorption cylinder 130 can slide along the opening groove 121 to the inner end of the opening groove 121, thereby facilitating the installation of the adsorption cylinder 130.

[0060] The other structures in this embodiment are similar to those in the above embodiments, and will not be described again here.

[0061] In summary, the drawer-type refill adsorption device and flue gas treatment system of this invention feature unitized and modular adsorbent replacement, making adsorbent replacement more convenient and faster. It eliminates the need for loading and unloading operations, reducing friction and collision between adsorbent particles, thus minimizing dust generation and adsorbent loss. Furthermore, the refill mechanism and adsorption cylinder have simple structures and low manufacturing costs, making them particularly suitable for flue gas adsorption in small-scale equipment, or for adsorbing small amounts of flue gas and for deep removal of clean gas.
