[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0029] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0031] In one embodiment, see Figure 1 , a zeolite adsorption device for purifying paint waste gas is provided, including an adsorption box support frame 13, on which a primary adsorption box 11 and a secondary adsorption box 12 are mounted; the top of the primary adsorption box 11 is set as an output end and is externally connected to a circulating pipeline 16, the bottom of the secondary adsorption box 12 is set with an input end and is externally connected to a secondary introduction machine pump 18, and the secondary introduction machine pump 18 is connected to the circulating pipeline 16; the primary adsorption box 11 is equipped with a primary adsorption auxiliary machine 15, the primary adsorption box 11 is externally connected to an air supply pipe body 14, and the output end of the air supply pipe body 14 is connected to the primary adsorption auxiliary machine 15; the secondary adsorption box 12 is provided with a secondary adsorption auxiliary machine 17; the top of the secondary adsorption box 12 is also respectively provided with a heat exchange pipe 21 and a circulation pump 23, the heat exchange pipe 21 is provided with a heater 22, the circulation pump 23 is externally connected to a reflux pipe 24, and the reflux pipe 24 is then connected to the heat exchange pipe 21.

[0032] The present embodiment is used for the purification of paint exhaust gas, and is designed to adopt a two-stage adsorption implementation method. The adsorption box support frame 13 is the main supporting structure and is installed on the equipment workstation. The gas supply pipe body 14 is the inlet pipe for the paint exhaust gas, and is externally connected to the paint exhaust gas supply pipeline. The primary adsorption box 11 is a preliminary purification structure for the paint exhaust gas. The primary adsorption box 11 is equipped with a primary adsorption auxiliary mechanism 15. The paint exhaust gas is introduced into the primary adsorption box 11 through the gas supply pipe body 14, and diffuses from the center line position of the primary adsorption box 11 to the periphery. At the same time, the primary adsorption auxiliary mechanism 15 in the primary adsorption box 11 is kept in a continuous motion state, so that the airflow is diffused in a ring shape along the box body of the primary adsorption box 11, thereby improving the movement path of the airflow in the primary adsorption box 11 and improving the adsorption degree of the airflow by the zeolite in the primary adsorption box 11.

[0033] The airflow is introduced into the turnover pipeline 16 at the top of the primary adsorption box 11, and is introduced into the secondary adsorption box 12 from the bottom of the secondary adsorption box 12. An output pump 19 is provided at the bottom of the other side of the secondary adsorption box 12 to provide drainage power. A secondary adsorption auxiliary machine 17 is provided in the secondary adsorption box 12. The secondary adsorption auxiliary machine 17 drives the paint exhaust gas in the secondary adsorption box 12 to move in a spiral manner in the inner cavity of the secondary adsorption box 12 toward the output pump 19. The zeolite in the secondary adsorption box 12 continuously adsorbs harmful gases in the exhaust gas during the movement. At the same time, the heat exchange tube 21, the heater 22, the circulation pump 23 and the reflux pipe 24 are combined into a thermal desorption system. The heat exchange tube 21 and the reflux pipe 24 are combined into a heat desorption system. It is a circulation pipeline with an inert gas built in it. The inert gas is used as the medium gas for heat conduction, and the heater 22 is used as a tool for continuous heating. The medium gas carries the high temperature into the inner cavity of the secondary adsorption box 12. The temperature of the zeolite is increased by heat conduction and maintained at a high temperature. When the paint exhaust gas is adsorbed by the zeolite, the volatile organic compounds (VOCs) therein will be oxidized and decomposed into harmless carbon dioxide (CO2) and water (H2O) under high temperature conditions, thereby decomposing the main harmful substances VOCs in the paint exhaust gas when absorbing the paint exhaust gas; this can achieve a purification effect on the one hand, and reduce the saturation of zeolite adsorption on the other hand, so that the zeolite adsorption amount is larger and the adsorption time is longer. The medium gas is then transferred through the circulation pump 23 as a conduction tool, and then recirculated into the heat exchange tube 21 through the reflux pipe 24, and then heated by the heater 22 (the medium gas will be mixed with carbon dioxide and water vapor, but the overall gas heating system is in a closed state, which does not affect the effect as a heat medium); the purified exhaust gas is output from the output pump 19 at the bottom to the next processing station.

[0034] In one embodiment, see Figures 1 to 3 This embodiment is a further design of the above embodiment. On this basis, the specific implementation structure of the primary adsorption auxiliary mechanism 15 is designed as follows:

[0035] The primary adsorption auxiliary mechanism 15 includes a hollow support shaft 35, a rotating disk 33 mounted on the hollow support shaft 35, and an inner disk support plate 34 arranged on the rotating disk 33. The rotating disk 33 is provided with two inner disk support plates 34 supported between the rotating disks 33 on both sides. The inner disk support plates 34 are arranged in an equiangular ring along the rotating disk 33 with the hollow support shaft 35 as the axis; the hollow support shaft 35 is provided with an air outlet surface 36, and the air outlet surface 36 is located between the rotating disks 33. The adsorption box support frame 13 is provided with a support bottom frame 31, and a box outer support frame 32 is provided and installed on the support bottom frame 31. The box outer support frame 32 is arranged on the periphery of the primary adsorption box 11 (such as Figure 2As shown in the figure, the primary adsorption box 11 is treated as a perspective with dotted lines), and both ends of the hollow support shaft 35 pass through the outer wall of the primary adsorption box 11 and are mounted on the outer support frame 32 of the box;

[0036] The output end of the gas transmission pipe body 14 is connected to the hollow support shaft 35, and the paint exhaust gas is introduced into the inner cavity of the primary adsorption box 11 from the air hole of the air outlet surface 36, which is located at the center line position of the primary adsorption box 11. When the paint exhaust gas is discharged, there is a movement tendency to diffuse toward the periphery; at the same time, the zeolite is arranged in the circular space area sandwiched between the rotating disks 33, a part of the zeolite is located in the center line area of ​​the space area, and the other part of the zeolite is located in the outer ring area outside the center line area, and the outer ring area is separated by the inner disk support plate 34; during operation, the rotating disk 33 and the inner disk support plate 34 are driven to rotate, thereby driving the airflow movement in the primary adsorption box 11, and at the same time driving the outer zeolite to flip, and the exhaust gas will then expand in a spiral manner in the inner cavity of the primary adsorption box 11, and due to the movement of the zeolite, the contact range with the zeolite is greatly increased, thereby improving the absorption effect of the zeolite.

[0037] In one case of this embodiment, see Figure 4 A shaft seat 41 is provided on one side of the outer support frame 32 of the box body, a shaft support sleeve 42 and a sealing connection sleeve 43 installed in the shaft support sleeve 42 are provided on the shaft seat 41, and a hollow shaft gas connection section 44 is installed at the input end of the hollow support shaft 35, and the hollow shaft gas connection section 44 is connected to the gas delivery pipe body 14. As for the connection design of the gas delivery pipe body 14, in this embodiment, the sealing connection sleeve 43 is used to connect the hollow shaft gas connection section 44 and the gas delivery pipe body 14, and the shaft support sleeve 42 is fixedly supported to ensure the stable connection between the pipe bodies.

[0038] In one case of this embodiment, see Figure 5 A driving mechanism 51 is arranged on the other side of the outer support frame 32 of the box body, and a driving frame 52 and a power motor 53 mounted on the driving frame 52 are mounted on the driving mechanism 51. A wheel connecting shaft 54 ​​is externally connected to the driving end of the hollow support shaft 35, and a transmission wheel 55 is mounted on the wheel connecting shaft 54. The driving end of the driving frame 52 and the transmission wheel 55 are connected through a transmission belt 56. During operation, the power motor 53 is used as a driving source to drive the transmission belt 56 to move, and the belt drive drives the transmission wheel 55 to move, thereby driving the hollow support shaft 35 to move, and then driving the rotating disk 33 and the inner disk support plate 34.

[0039] In one embodiment, see Figure 1 and Figure 6 This embodiment is a further design of the above embodiment. On this basis, the specific implementation structure of the secondary adsorption auxiliary mechanism 17 is designed as follows:

[0040] The secondary adsorption auxiliary mechanism 17 includes a main support roller 61 of the frame, a frame support plate 65 and a transverse support beam 66. A roller outer support tube 64 is installed on the axial surface of the main support roller 61 of the frame. The driving end of the main support roller 61 of the frame is externally connected to an extended roller segment 62, and the extended roller segment 62 is connected to a power roller 63; the frame support plate 65 is provided with a plurality of roller outer support tubes 64 that are equidistantly arranged, and the transverse support beams 66 are provided with a plurality of transverse support beams 66 that are erected between the frame support plates 65, and adjacent transverse support beams 66 are arranged at equal angles.

[0041] The exhaust gas is input into the inner cavity of the secondary adsorption box 12 by the secondary inlet pump 18 at the bottom of the secondary adsorption box 12. The inner cavity of the secondary adsorption box 12 is filled with zeolite, and the zeolite is filled in the structural gap of the secondary adsorption auxiliary mechanism 17. During operation, the power roller 63 is used as a power input tool to drive the extension roller segment 62 to move, thereby driving the overall main support roller 61 of the frame to move, and the frame support plate 65 and the cross support beam 66 on the periphery thereof rotate accordingly. During the movement, the rotating structure of the frame support plate 65 drives the zeolite and the airflow to flip, and the cross support beam 66 is used to guide the airflow toward the discharge side of the secondary adsorption box 12 during the rotation process, thereby driving the airflow to rotate in the inner cavity of the secondary adsorption box 12 as a whole, and filling and moving between the zeolites in the inner cavity of the secondary adsorption box 12 in a spiral trajectory, so that the zeolite can fully absorb the harmful positions in the airflow to ensure the absorption effect.

[0042] In one case of this embodiment, see Figure 6 , Figure 7 and Figure 8 The horizontal support beam 66 is a strip plate structure, and a guide surface 74 is provided on one side of the horizontal support beam 66, and a guide line groove 75 is provided on the guide surface 74; the frame support plate 65 is provided with disk grooves 71 at equal angles, and a disk groove section 77 is formed in the disk groove 71, and the horizontal support beam 66 passes through the disk groove section 77 of the frame support plate 65, and the horizontal support beam 66 is installed in the groove on one side of the disk groove 71, and the swing bolt 72 is installed in the groove on the other side of the disk groove 71 through the inner groove recess 76, and a swing plate 73 is provided on the swing bolt 72.

[0043] As an example, a mechanism arrangement is shown in the figure. In this embodiment, three frame support plates 65 are arranged on the periphery of the roller outer support tube 64. Four plate body grooves 71 are opened on the periphery of the plate body of each frame support plate 65, so four transverse support beams 66 are also correspondingly arranged. The design function of this embodiment is:

[0044] Firstly, it plays a role in heat conduction. The cross beam 66 is a strip plate structure, and the thermal desorption system composed of the heat exchange tube 21, the heater 22, the circulation pump 23 and the return pipe 24 can help improve the conduction of heat energy between the zeolites, thereby facilitating the zeolite to adsorb exhaust gas, and cooperate with the high-temperature heat energy it carries to perform an endothermic reaction to decompose volatile organic compounds (VOCs).

[0045] Secondly, during the movement, the airflow rotates with the movement of the frame support plate 65, but the airflow will inevitably be blocked by the horizontal support beam 66 during the rotation process, so that it will be retained on the side of the guide surface 74, and a number of guide grooves 75 are set on the guide surface 74, and the guide grooves 75 are used to guide the flow of the airflow, thereby assisting the backward movement of the airflow: the prior art often adopts a spiral guide structure, which will also drive the zeolite to move while guiding the airflow, resulting in the disadvantage of zeolite accumulation on one side of the chassis. In this case, the present embodiment has the effect of guiding the airflow but will not affect the zeolite, so that the zeolite can be evenly distributed while guiding the airflow.

[0046] Thirdly, the inner diameter of the groove of the disc body groove 71 is larger than the outer diameter of the cross beam 66, so that there is a certain gap in the inner space of the disc groove interval 77. A swing plate 73 is provided at the groove on the other side of the disc body groove 71. The swing plate 73 is a square plate and is installed by a swing bolt 72. It can swing slightly. Then, during the rotation of the overall secondary adsorption auxiliary mechanism 17, under the influence of the movement trend, the swing plate 73 will swing irregularly, and the zeolite in the disc groove interval 77 will be shaken during the swinging process. In this way, the zeolite near the airflow direction area will show a slightly irregular movement trend. On the one hand, it will not hinder the airflow, and on the other hand, it will further improve the contact effect between the airflow and the zeolite.

[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

[0048] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
