DETAILED DESCRIPTION

[0027] ​​The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1: Figures 1-3 As shown, the technical solution adopted by the present invention is as follows: an activated coking tail gas treatment device includes a flushing pipe 2, and an air intake device is detachably installed on the top of the flushing pipe 2.

[0029] The air intake system includes a fan 4. The top of the flushing pipe 2 is detachably mounted with an intake pipe 1 via bolts 3. A support plate is fixedly attached to the interior of the intake pipe 1, and the fan 4 is fixedly attached to the top of the support plate. Connecting the top of the intake pipe 1 to the exhaust output port generated during the carbonization process and starting the fan 4 draws the exhaust gas into the flushing pipe 2 for easy treatment.

[0030] The outer surface of the flushing pipe 2 is fixedly connected to a water tank 5 , and a water inlet is provided on the top of the water tank 5 so that water can be passed into the water tank 5 through the water inlet.

[0031] A water pump is fixedly mounted inside the water tank 5. The pump's input is fixedly connected to a water inlet pipe, which extends into the bottom of the water tank 5. The pump's output is fixedly connected to a circular outlet pipe, to which several nozzles 6 are evenly and fixedly connected. Each nozzle 6 is fixedly inserted through the side of the flushing pipe 2. The spraying ends of the nozzles 6 are positioned within the flushing pipe 2, allowing water from the water tank 5 to be sprayed into the flushing pipe 2.

[0032] A filter tube 7 is detachably mounted on the bottom of the flushing tube 2 .

[0033] The filter tube 7 is connected to the flushing tube 2 by bolts 3. The inner diameters of the intake tube 1, flushing tube 2 and filter tube 7 are equal, so that the exhaust gas passes through the intake tube 1, flushing tube 2 and filter tube 7 in sequence, and is processed by the flushing tube 2 and filter tube 7.

[0034] The interior of the filter tube 7 is slidably provided with a mounting frame 8, and the interior of the mounting frame 8 is provided with a filter cotton net 9. When the mounting frame 8 slides on the filter tube 7, the filter cotton net 9 is driven to move together.

[0035] Two connectors are symmetrically fixed on the bottom surface of the mounting frame 8, and two clamping members are symmetrically provided on the filter tube 7. When the mounting frame 8 is located in the filter tube 7, the connectors correspond to the clamping members one by one and the connectors are clamped in the corresponding clamping members.

[0036] The connecting piece comprises a clamping block 11. Two limiting blocks 10 are symmetrically fixed on the outer surface of the mounting frame 8, and two limiting grooves 15 are symmetrically formed on the inner wall of the filter pipe 7, and the limiting blocks 10 are slidingly arranged in the corresponding limiting grooves 15. The limiting grooves 15 position the limiting blocks 10, and then position the up-and-down sliding of the mounting frame 8 in the filter pipe 7. The top end of the limiting groove 15 is flush with the top surface of the filter pipe 7, facilitating the installation and disassembly of the mounting frame 8.

[0037] The clamping block 11 is fixedly connected to the bottom of the corresponding limiting block 10, so that there is one clamping block 11 in each limiting groove 15. Second clamping grooves 21 are formed on the corresponding two outer surfaces of the clamping block 11, and the second clamping grooves 21 are arc-shaped.

[0038] The clamping piece comprises an elastic plate 13. A fixed plate 12 is fixedly connected to the inside of each limiting groove 15, and the elastic plate 13 is fixedly connected to the top of the corresponding fixed plate 12.

[0039] The elastic plate 13 is U-shaped, the two ends of the opening of the elastic plate 13 are close to each other, and the two ends of the opening of the elastic plate 13 are arc-shaped. The shape of the two ends of the opening of the elastic plate 13 is matched with the shape of the second clamping groove 21. The bottom surface of the clamping block 11 is arc-shaped, the clamping block 11 is movably arranged in the corresponding elastic plate 13, and the two ends of the opening of the elastic plate 13 are movably arranged in the corresponding second clamping groove 21.

[0040] The elastic plate 13 is a functional part that works by elasticity, which deforms under external force and returns to its original state after the external force is removed. Elastic material refers to a material that deforms under external force and returns to its original state after the external force is removed. The elastic material is a product.

[0041] A first spring 14 is fixedly connected to the corresponding two sides of each elastic plate 13, and the other end of the first spring 14 is fixedly connected to the side wall of the corresponding limiting groove 15. The first spring 14 facilitates the rapid recovery of the elastic plate 13, and makes the clamping of the elastic plate 13 on the clamping block 11 more stable.

[0042] Working principle:

[0043] In use, the top end of the air inlet pipe 1 is connected with the tail gas output end generated in the carbonization process. Water is introduced into the inside of the water tank 5.

[0044] Start the fan 4 and the water pump.

[0045] The fan 4 generates suction force to suck the tail gas into the air inlet pipe 1, and the tail gas will enter the flushing pipe 2.

[0046] The water pump draws water from the water tank 5 into the outlet pipe, where it is then sprayed through several nozzles 6 into the flushing pipe 2. The exhaust gas comes into contact with the water and then falls onto the filter mesh 9, soaking it. The exhaust gas is then filtered through the filter mesh 9 and discharged through the bottom end of the filter pipe 7.

[0047] When the filter cotton mesh 9 needs to be replaced, the bolts 3 on the filter tube 7 are removed to separate the filter tube 7 from the flushing tube 2.

[0048] Pull the installation frame 8 upwards to slide the installation frame 8 upwards in the filter tube 7 , driving the limiting block 10 to slide upwards in the limiting groove 15 .

[0049] The limiting block 10 drives the clamping block 11 to move upward, so that the clamping block 11 presses the two ends of the opening of the elastic plate 13, so that the opening of the elastic plate 13 opens, and the two ends of the opening of the elastic plate 13 leave the second clamping groove 21. At the same time, the elastic plate 13 presses the first spring 14.

[0050] After the clamping block 11 leaves the elastic plate 13 , the elasticity of the elastic plate 13 and the elastic force of the first spring 14 will squeeze the two ends of the opening of the elastic plate 13 toward each other until the elastic plate 13 returns to its original shape.

[0051] When installing the replaced filter cotton mesh 9, move the installation frame 8 to the top of the filter tube 7 so that the limiting blocks 10 and the limiting grooves 15 correspond one to one.

[0052] Pressing down the mounting frame 8 causes the limit block 10 to slide downward into the limit slot 15, driving the clamping block 11 downward. The clamping block 11 presses the two ends of the opening of the elastic plate 13 and compresses the first spring 14. At this time, the first spring 14 exerts a thrust on the elastic plate 13.

[0053] As the block 11 moves downward, the two ends of the opening of the elastic plate 13 are locked into the second slots 21. The elastic plate 13 clamps the block 11, thereby positioning the mounting frame 8 within the filter tube 7. The filter tube 7 is then fixed to the bottom of the flushing tube 2 using bolts 3, and the exhaust gas can continue to be processed through the filter tube 7.

[0054] Example 2: Figures 4-5 As shown, the difference between this embodiment and embodiment 1 is that two connecting pieces are symmetrically fixed on the bottom surface of the mounting frame 8, and two clamping pieces are symmetrically provided on the filter tube 7. When the mounting frame 8 is located within the filter tube 7, the connecting pieces correspond one-to-one with the clamping pieces, and the connecting pieces are clamped into the corresponding clamping pieces.

[0055] The connecting piece comprises a clamping plate 16. Two limiting blocks 10 are symmetrically fixed on the outer surface of the mounting frame 8, two limiting grooves 15 are symmetrically formed on the inner wall of the filter pipe 7, and the limiting blocks 10 are slidingly arranged in the corresponding limiting grooves 15. The limiting grooves 15 position the limiting blocks 10, and thus position the up-and-down sliding of the mounting frame 8 in the filter pipe 7. The top end of the limiting groove 15 is flush with the top surface of the filter pipe 7, facilitating the installation and dismounting of the mounting frame 8.

[0056] The clamping plate 16 is fixedly connected to the bottom of the corresponding limiting block 10, so that there is one clamping plate 16 in each limiting groove 15. The clamping plate 16 is L-shaped, and the end of the clamping plate 16 away from the limiting block 10 is arc-shaped.

[0057] The clamping piece comprises a rotating plate 18. Two connecting plates 17 are fixedly connected in the interior of each limiting groove 15, and the rotating plate 18 is rotatably connected between the two connecting plates 17. A first clamping groove 19 is formed on one side of the rotating plate 18, and the shape of the first clamping groove 19 is adapted to the shape of the arc-shaped end of the clamping plate 16. The end of the clamping plate 16 is movably arranged in the first clamping groove 19.

[0058] The other side of the rotating plate 18 is fixedly connected with a second spring 20, and the other end of the second spring 20 is fixedly connected to the side wall of the corresponding limiting groove 15. One side of the top of the rotating plate 18 is provided with a round corner, which facilitates the pushing of the clamping plate 16 to the rotating plate 18.

[0059] Working principle:

[0060] When the filter cotton net 9 needs to be replaced, the bolt 3 on the filter pipe 7 is removed, and the filter pipe 7 is separated from the flushing pipe 2.

[0061] The mounting frame 8 is pulled upwards, so that the mounting frame 8 slides upwards in the filter pipe 7, and the limiting block 10 slides upwards in the interior of the limiting groove 15.

[0062] The limiting block 10 drives the clamping plate 16 to move upwards, one end of the clamping plate 16 pushes the rotating plate 18 to rotate, and the rotating plate 18 compresses the second spring 20.

[0063] After one end of the clamping plate 16 leaves the first clamping groove 19, the rotating plate 18 is pushed to rotate under the elastic force of the second spring 20, so that the rotating plate 18 abuts against one end of the clamping plate 16.

[0064] When the clamping plate 16 leaves the rotating plate 18, the rotating plate 18 returns to the initial state.

[0065] When the filter cotton net 9 is installed and replaced, the mounting frame 8 is moved to the top of the filter pipe 7, so that the limiting block 10 and the limiting groove 15 correspond to each other.

[0066] The installation frame 8 is pressed downward, the limiting block 10 is slid downward into the limiting groove 15, and the clamping plate 16 is moved downward. The end of the clamping plate 16 is in contact with the rotating plate 18, and the clamping plate 16 will extrude the rotating plate 18, so that the rotating plate 18 is rotated and the second spring 20 is compressed.

[0067] When the end of the clamping plate 16 is located in the first clamping groove 19, the second spring 20 pushes the rotating plate 18, so that the inner wall of the first clamping groove 19 is in abutment with the clamping plate 16. Then, one end of the clamping plate 16 is positioned in the first clamping groove 19, and the installation frame 8 is positioned in the filter pipe 7. Then, the filter pipe 7 is fixed at the bottom of the flushing pipe 2 by using the bolt 3, and the tail gas can be continuously treated through the filter pipe 7.

[0068] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
