[0002] In life, a lot of waste is usually generated. Among them, some hazardous waste needs to be treated by incineration due to its special physical and chemical properties. Although most of the hazardous waste can be treated cleanly by incineration, the tail gas generated by incineration is still harmful to a certain extent. Therefore, a tail gas treatment device is also needed to treat its tail gas.
[0003] Most of the existing tail gas treatment devices have a two-layer design. First, a filter screen is used to filter the particulate matter in the tail gas, and then substances such as activated carbon are used to collect the harmful gases in it. Once the filter screen is blocked, the gas flow rate will be reduced, which may lead to a decrease in the purification efficiency. The operator needs to replace or clean the filter plate again to make the device return to normal operation. The purification efficiency of the overall device is relatively low. For this reason, a tail gas treatment device for incinerating hazardous waste is proposed to solve the above problems. Summary of the Utility Model

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0030] Referring to Figure 1 - Figure 3 In one embodiment provided by the present utility model: A waste incineration tail gas treatment device includes an intake pipe 1 for allowing tail gas to enter the interior of the device. The right end of the intake pipe 1 is provided with a collection pipe 2 for temporarily storing the tail gas. The top of the collection pipe 2 is provided with a drainage pipe 3 for blocking the tail gas to prevent it from entering the interior of the exhaust pipe 4 without being filtered. The top of the drainage pipe 3 is provided with an exhaust pipe 4 for discharging the purified tail gas. The bottom of the collection pipe 2 is provided with a collection assembly 6 for collecting the filtered particulate matter. The collection assembly 6 includes a bottom plate 65 for closing the bottom opening of the collection pipe 2. The bottom plate 65 is inserted into the bottom of the collection pipe 2. The top of the bottom plate 65 is provided with a filter assembly 5 for filtering the tail gas. The filter assembly 5 includes a rotating shaft 53 for supporting the rotation of the filter sleeve 51. The rotating shaft 53 penetrates and is rotatably connected to the top of the bottom plate 65.
[0031] Referring to Figure 1 - Figure 3The filter assembly 5 also includes a filter sleeve 51 for filtering particulate matter in the exhaust gas. The bottom end of the filter sleeve 51 is detachably mounted on the top of the rotating shaft 53. When the rotating shaft 53 rotates, the filter sleeve 51 will also rotate accordingly. The inner wall of the filter sleeve 51 is detachably mounted with an absorption tube 52 for absorbing harmful substances in the exhaust gas. Activated carbon is stored inside the absorption tube 52, which can be used to absorb harmful gases in the exhaust gas. The cross-section of the drainage tube 3 is set to be trapezoidal. The inner diameter of the drainage tube 3 is the same as the outer diameter of the absorption tube 52. The exhaust gas must pass through the filter sleeve 51 and the absorption tube 52 before it can be discharged from the inside of the drainage tube 3. The bottom end of the rotating shaft 53 is fixedly connected with a rotary shaft 53 for facilitating the operator to rotate the rotary shaft 53. The top of the bottom plate 65 is fixedly connected to the handle 54 of the shaft 53 and a rubber sleeve 58 for closing the outer wall of the shaft 53. The shaft 53 passes through and rotates on the bottom end of the rubber sleeve 58. By providing the rubber sleeve 58, the exhaust gas can be prevented from leaving the interior of the collecting pipe 2 from the shaft 53. The bottom end of the bottom plate 65 is fixedly connected to a storage box 56 for accommodating a shift block 57. The right end of the storage box 56 passes through and is slidably connected to a shift block 57 for fixing the shaft 53 and the bottom plate 65. The outer wall of the shaft 53 is provided with a fixing groove 55 for accommodating the shift block 57. The fixing groove 55 and the shift block 57 are adapted to each other. When the shift block 57 is inserted into the fixing groove 55, the shaft 53 will be fixed and cannot rotate.
[0032] Reference Figure 2 - Figure 4 The rear end of the shift block 57 is fixedly connected to a slide plate 59 for driving the shift block 57 to move. The right end of the slide plate 59 is fixedly connected to a return spring 510 for pulling the slide plate 59. The right end of the return spring 510 is fixedly connected to the inner wall of the storage box 56. When the slide plate 59 is not at the center line position inside the storage box 56, the return spring 510 will return to the center position by deformation. The collection assembly 6 also includes a collection box 61 for collecting particulate matter. The collection box 61 is plugged into the outer wall of the rubber sleeve 58. The collection box 61 is set to a semicircular ring. Two sets of collection boxes 61 can be spliced oppositely to complete The outer wall of the fully wrapped rubber sleeve 58, the bottom end of the collecting tube 2 is fixedly connected with a connecting block 62 for fixing the bottom plate 65, the top of the connecting block 62 is provided with a connecting groove 64 for accommodating the shift block 57, the connecting groove 64 and the shift block 57 are adapted to each other, when the shift block 57 is inserted into the connecting groove 64, the bottom plate 65 will be fixed to the bottom end of the collecting tube 2 and cannot be detached, the front end of the shift block 57 passes through and is slidably connected to the front end of the storage box 56, and the front end of the shift block 57 can be driven to move left and right by shifting it, and the inner wall of the collecting tube 2 is fixedly connected with a cleaning brush 63 for cleaning the outer wall of the filter sleeve 51.
[0033] Working principle: When there are excessive particles on the outer wall of the filter sleeve 51, resulting in a decline in the filtering effect of the device, the dial block 57 can be first toggled to the left to drive it to move leftward out of the inside of the fixing groove 55, and then the rotary handle 54 can be rotated to drive the filter sleeve 51 to rotate. In this way, the filter sleeve 51 can use the unobstructed surface at the other end to face the air inlet pipe 1, so that the filtering effect of the device can be restored. Then, the dial block 57 can be released, and the return spring 510 will pull the slide plate 59 to drive the dial block 57 to move rightward and re-engage into the inside of the fixing groove 55 to fix the rotating shaft 53 again.
[0034] When the filter sleeve 51 rotates, the cleaning brush 63 will rub against its outer wall, forcing the particles adhering to its outer wall to detach. The particles will move downward under the action of gravity and fall into the inside of the collection box 61. When it is necessary to clean the collection box 61, the air supply can be first cut off, and then the dial block 57 can be toggled to the right to drive it to move rightward out of the inside of the connection groove 64. Then, the bottom plate 65 and the components on its top will move downward under the action of gravity. When the collection box 61 is completely detached from the inside of the collection pipe 2, the collection box 61 can be taken out for cleaning.
[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
