Description

Technical Field

[0001] This utility model belongs to the field of waste gas treatment technology, and in particular relates to an activated carbon adsorption device. Background Technology

[0002] Activated carbon adsorption is a common separation, purification, and decontamination technology that is widely used in various fields. Activated carbon has porosity, chemical stability, and renewability, so it can efficiently adsorb harmful substances in waste gas.

[0003] Based on the renewability of activated carbon, traditional activated carbon adsorption devices typically employ different methods to regenerate it. For example, Chinese patent application number (2022112222591) discloses an activated carbon box for waste gas treatment. This application installs multiple detachable activated carbon storage components. After the activated carbon reaches adsorption saturation, the activated carbon storage components are removed and replaced sequentially to ensure waste gas treatment efficiency. However, when replacing the activated carbon storage components, this application requires removing the existing activated carbon components and placing new ones, which is complex, time-consuming, and labor-intensive, and needs improvement. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing an activated carbon adsorption device that can automatically switch when activated carbon needs regeneration, thus saving time and effort.

[0005] In view of this, the present invention provides an activated carbon adsorption device, comprising:

[0006] The housing is equipped with two activated carbon units for adsorbing waste gas, each with an air inlet on the opposite side and an outlet and a collection port on the top.

[0007] An air intake box is installed between two boxes, and both sides are equipped with air outlet pipes adapted to the air inlets, which are slidably connected between the two boxes.

[0013] The frame is detachably attached to the inner wall of the box.

[0014] Metal mesh, mounted on a frame, is used to pass exhaust gas through activated carbon plates.

[0015] In the above technical solution, the heating mechanism further includes:

[0016] The heating tube has a heating medium flowing inside, and both ends extend out of the housing, forming an inlet and an outlet respectively.

[0017] The heating elements are arranged in a serpentine pattern.

[0018] In the above technical solution, the air intake box further includes:

[0019] The intake pipe is installed on the side of the intake box and is used to guide exhaust gas into the intake box.

[0020] The first opening and closing component is installed on the air outlet pipe;

[0021] The housing is equipped with a second opening and closing component at the air inlet, which, along with the first opening and closing component, is used to close the air inlet when the air outlet pipe is not inserted into the air inlet and to open the air inlet when the air outlet pipe is inserted into the air inlet. At the same time, the first opening and closing component and the second opening and closing component trigger each other.

[0022] In the above technical solution, the first opening and closing element further includes:

[0023] A sleeve is fitted onto the vent pipe, and multiple first vent holes are opened on the radial circumference of the sleeve.

[0024] The first spring is sleeved on the air outlet pipe, and its two ends abut against the sleeve and the air inlet box respectively;

[0025] The first sealing plate is installed on the axial end face of the sleeve and the axial end face of the air outlet pipe;

[0026] The air outlet pipe has a second air outlet hole on its radial surface. When the first spring is compressed, the first air outlet hole and the second air outlet hole correspond to each other. After the first spring is released from compression, the first air outlet hole and the second air outlet hole are staggered.

[0027] In the above technical solution, the second opening and closing element further includes:

[0028] The second sealing plate is installed inside the box and is used to seal and open the air inlet;

[0029] The second spring has its two ends connected to the second sealing plate and the inner wall of the box, respectively.

[0030] When the second spring is stretched, the second sealing plate opens the air inlet; when the second spring is unstretched, the second sealing plate closes the air inlet.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0046] Example 1:

[0047] This embodiment provides an activated carbon adsorption device, including:

[0048] The box 1 is equipped with two activated carbons for adsorbing waste gas, each with an air inlet 2 on the opposite side and an exhaust outlet 3 and a collection outlet 4 on the top surface.

[0049] An air intake box 5 is installed between two boxes 1, and both sides are provided with air outlet pipes 6 adapted to the air inlet 2, and are slidably connected between the two boxes 1.

[0050] The drive unit 7 is installed on the side of the air intake box 5 and is used to push the air intake box 5 to move, and to switch between the two boxes 1 in connection.

[0051] Among them, the driving component 7 can be a cylinder, and the sliding connection of the air intake box 5 can be a slider and slide rail structure, both of which are existing technologies and will not be described in detail here.

[0052] As can be seen from this embodiment, by setting two boxes 1 and setting a movable air intake box 5 in the two boxes 1, the air intake box 5 is moved by the driving component 7, thereby switching between the two boxes 1. One box 1 is used for adsorption and the other box 1 is used for regeneration, and vice versa. No manual operation is required, which effectively improves convenience, saves time and effort, and can effectively improve the waste gas treatment efficiency by adsorption and regeneration simultaneously.

[0053] Example 2:

[0054] This embodiment provides an activated carbon adsorption device, which, in addition to the technical solutions of the above embodiments, also has the following technical features and further includes:

[0055] Multiple activated carbon plates 8 are arranged at equal intervals inside the box 1 and are filled with activated carbon.

[0056] Multiple heating mechanisms 9 are provided and installed between two adjacent activated carbon plates 8.

[0057] As can be seen from this embodiment, by alternating between the activated carbon plate 8 and the heating mechanism 9, the uniformity and efficiency of the regeneration of the activated carbon plate 8 can be effectively improved, while energy consumption can be reduced, thus achieving the effect of energy saving.

[0058] Example 3:

[0059] This embodiment provides an activated carbon adsorption device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the activated carbon plate 8 includes:

[0060] Frame 80 is detachably connected to the inner wall of housing 1;

[0061] Metal mesh 81 is installed on frame 80 and is used for passing exhaust gas through activated carbon plate 8;

[0062] The detachable connection between the frame 80 and the inner wall of the box 1 can be made by bolts.

[0063] As can be seen from this embodiment, by setting the activated carbon plate 8 as a metal mesh 81 and a frame 80, it is easy to ensure that the exhaust gas passes through the activated carbon plate 8, and at the same time, the activated carbon plate 8 can be filled to ensure the stability and uniformity of the placement of the activated carbon.

[0064] The detachable connection of the frame 80 facilitates the installation and removal of the activated carbon plate 8, improving the convenience of maintenance and replacement of the activated carbon plate 8.

[0065] Example 4:

[0066] This embodiment provides an activated carbon adsorption device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the heating mechanism 9 includes:

[0067] Heating tube 90, with heating medium flowing inside, and both ends extending out of the housing 1, forming an inlet end 91 and an outlet end 92 respectively;

[0068] Among them, the heating tubes 90 are arranged in a serpentine pattern;

[0069] Meanwhile, steam can be used as the heating medium.

[0070] As can be seen from this embodiment, by using heating tubes 90 and introducing heating medium inside, the structure is simple and the energy consumption is low. At the same time, the serpentine arrangement of heating tubes 90 can effectively improve the heating uniformity of activated carbon plate 8 and ensure the thermal desorption efficiency and effect of activated carbon.

[0071] Example 5:

[0072] This embodiment provides an activated carbon adsorption device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the air inlet box 5 further includes:

[0073] An intake pipe 50 is installed on the side of the intake box 5 and is used to introduce exhaust gas into the intake box 5.

[0074] The first opening and closing element 51 is installed on the air outlet pipe 6;

[0075] The housing 1 is provided with a second opening and closing element 10 at the air inlet 2. Both the first opening and closing element 51 and the second opening and closing element 10 are used to close the air inlet 2 when the air outlet pipe 6 is not inserted into the air inlet 2 and to open the air inlet 2 when the air outlet pipe 6 is inserted into the air inlet 2. At the same time, the first opening and closing element 51 and the second opening and closing element 10 trigger each other.

[0076] As can be seen from this embodiment, the first opening and closing element 51 and the second opening and closing element 10 can seal the exhaust pipe 6 and the air inlet 2 when they are not connected, thereby preventing the leakage of waste gas and avoiding pollution to the treatment environment.

[0077] Example 6:

[0078] This embodiment provides an activated carbon adsorption device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the first opening and closing element 51 includes:

[0079] The sleeve 510 is fitted onto the air outlet pipe 6, and a plurality of first air outlet holes 511 are opened on the radial circumference of its surface;

[0080] The first spring 512 is sleeved on the air outlet pipe 6, and its two ends abut against the sleeve 510 and the air inlet box 5 respectively.

[0081] The first sealing plate 513 is installed on the axial end face of the sleeve 510 and the axial end face of the air outlet pipe 6.

[0082] The air outlet pipe 6 has a second air outlet hole 514 circumferentially opened on its radial surface. When the first spring 512 is compressed, the first air outlet hole 511 and the second air outlet hole 514 correspond to each other. After the first spring 512 is decompressed, the first air outlet hole 511 and the second air outlet hole 514 are staggered.

[0083] Meanwhile, the two ends of the first spring 513 are fixedly connected to the sleeve 510 and the air intake box 5 respectively. Specifically, a clamping plate can be used and bolts can be used for fastening, which is existing technology and will not be described in detail here.

[0084] As can be seen from this embodiment, with the above structure, when the exhaust pipe 6 is not inserted into the air inlet 2, the first opening and closing member 51 is not triggered by the second opening and closing member 10. Therefore, the first exhaust hole 511 and the second exhaust hole 514 can be staggered under the action of the first spring 512, which can effectively prevent the exhaust gas from leaking from the exhaust pipe 6, ensure the treatment of exhaust gas, and avoid affecting the treatment environment. When the exhaust pipe 6 is inserted into the air inlet 2, the first opening and closing member 51 is triggered by the second opening and closing member 10, which presses the sleeve 510, thereby compressing the first spring 512, so that the first exhaust hole 511 and the second exhaust hole 514 are aligned, thereby connecting the air inlet box 5 with the box body 1, ensuring the delivery of exhaust gas.

[0085] Example 7:

[0086] This embodiment provides an activated carbon adsorption device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the second opening and closing element 10 includes:

[0087] The second sealing plate 100 is installed inside the housing 1 and is used to close and open the air inlet 2;

[0088] The second spring 101 has its two ends connected to the second sealing plate 100 and the inner wall of the box 1, respectively;

[0089] When the second spring 101 is stretched, the second sealing plate 100 opens the air inlet 2; when the second spring 101 is unstretched, the second sealing plate 100 closes the air inlet 2.

[0090] Meanwhile, the two ends of the second spring 101 can be fixedly connected to the second sealing plate 100 and the inner wall of the box 1. Specifically, a clamping plate can be used and bolts can be used for fastening. This is existing technology and will not be described in detail here.

[0091] As can be seen from this embodiment, when the exhaust pipe 6 is continuously inserted into the air inlet 2, the sleeve 510 will first abut against the second sealing plate 100, thereby pushing the second sealing plate 100 to open the air inlet 2 and stretching the second spring 101. When the elastic restoring force of the second spring 101 is greater than the elastic restoring force of the first spring 512, it will push the first spring 512 to compress until the exhaust pipe 6 is inserted into the air inlet 2 and the first exhaust hole 511 is aligned with the second blowing hole, thereby realizing the connection between the air inlet box 5 and the box body 1, ensuring the delivery of exhaust gas, and automatically triggering the opening and closing, effectively improving convenience.

[0092] Example 8:

[0093] This embodiment provides an activated carbon adsorption device, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0094] The housing 1 includes an adsorption chamber 11 and a collection chamber 12, and a partition 13 is provided between the collection chamber 12 and the adsorption chamber 11. An air passage 14 is provided on the partition 13, and the air passage 14 is correspondingly provided with the heating mechanism 9.

[0095] Among them, the discharge port 3 is connected to the adsorption chamber 11, and the collection port 4 is connected to the collection chamber 12;

[0096] Meanwhile, discharge port 3 is connected to a discharge pipe, such as a vent pipe, and collection port 4 is connected to a collection pipe, which is then connected to a storage tank or secondary treatment device.

[0097] As can be seen from this embodiment, the collection chamber 12 and the collection port 4 facilitate the collection of waste gas generated during the regeneration of activated carbon, making it easier to reuse and recycle, thus realizing the reuse of resources.

[0098] In addition, it should be noted that this application also provides multiple rubber sealing elements, such as the annular sealing gasket at the air inlet 2 when the air inlet box 5 abuts against the surface of the box body 1, the annular rubber ring between the sleeve 510 and the air outlet pipe 6, and the annular sealing gasket between the second sealing plate 100 and the inner wall of the box body 1 at the air inlet 2. These are all existing technologies, and corresponding sealing elements can be set as needed. They will not be described in detail here.

[0099] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
