Furthermore, activated carbon becomes clogged with impurities after a period of use, requiring regular replacement to maintain adsorption efficiency. Existing activated carbon adsorption layers are mostly fixed inside the device, making replacement inconvenient. Utility Model Content

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0032] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Please refer to Figures 1-2 An embodiment of this utility model provides a petrochemical waste gas adsorption device, comprising:

[0034] Bracket 1;

[0035] Tank 2 is fixedly mounted on support 1. The bottom of tank 1 is divided by partition 21 to form discharge chamber 22. The bottom of tank 2 is connected to discharge pipe 23, and discharge valve 24 is installed on discharge pipe 23.

[0036] Adsorption assembly 3 is fixedly mounted on partition 21. Adsorption assembly 3 includes a first partition cylinder 31, a second partition cylinder 32, and a third partition cylinder 33 arranged sequentially from the inside out. Each of the first, second, and third partition cylinders has numerous through holes 34. The top of the third partition cylinder 33 is sealed to the top of the tank body 2. The top of the second partition cylinder 32 is lower than the third partition cylinder 33, and the top of the first partition cylinder 31 is lower than the second partition cylinder 32. A first adsorption chamber is formed between the first partition cylinder 31 and the second partition cylinder 32. The second partition cylinder 32 and the third partition cylinder 33... A second adsorption chamber is formed between the first and second adsorption chambers. Both the first and second adsorption chambers are filled with activated carbon particles 35. Several first connecting pipes 36, which connect to the discharge chamber 22, are evenly distributed around the bottom of the first adsorption chamber. Each first connecting pipe 36 is equipped with a first solenoid valve 37. Several second connecting pipes 38, which connect to the discharge chamber 22, are evenly distributed around the bottom of the second adsorption chamber. Each second connecting pipe 38 is equipped with a second solenoid valve 39. An air inlet pipe 25, which connects to the first partition cylinder 31, is provided on one side of the tank body 2. An air outlet pipe 26, which connects to the space between the tank body 2 and the third partition cylinder 33, is provided on the other side.

[0037] The feeding component 4 is fixedly installed on the support 1, located above the tank 2, and connected to the top of the adsorption component 3. It is used to inject activated carbon particles 35 into the adsorption component 3.

[0038] The feeding component 5 is located at the top of the first separator cylinder 31 and is used to guide the activated carbon particles 35 injected by the feeding component 4, so that they switch between being injected into the first adsorption chamber and being injected into the second adsorption chamber.

[0039] In this embodiment, when treating petrochemical waste gas, it is injected into the first separator cylinder 31 through the inlet pipe 25. The petrochemical waste gas passes through the activated carbon particles 35 in the first and second adsorption chambers through the through holes 34. Harmful gases are adsorbed by the activated carbon particles 35. The treated gas enters the tank 2 and is discharged through the outlet pipe 26. The annular structure of the first and second adsorption chambers effectively increases the adsorption area of ​​the activated carbon particles 35 in the same space, thus improving the adsorption effect.

[0040] When periodically replacing the activated carbon granules 35, firstly, open each of the first solenoid valves 37. The activated carbon granules 35 in the first adsorption chamber enter the discharge chamber 22 through each of the first connecting pipes 36. Open the discharge valve 24 to discharge the activated carbon granules 35 through the discharge pipe 23 and collect them in the collection container. Then, the feeding component 4 injects activated carbon granules 35 into the adsorption component 3, and the guiding component 5 guides them into the first adsorption chamber. After the activated carbon granules 35 are filled, close the feeding component 4 to complete the replacement of the activated carbon granules 35 in the first adsorption chamber. Then, following the same steps, guide the activated carbon granules 35 injected by the feeding component 4 into the second adsorption chamber through the guiding component 5 to complete the replacement of the activated carbon granules 35 in the second adsorption chamber. During the replacement of the activated carbon granules 35, the activated carbon granules 35 in the first or second adsorption chamber are always in working condition, realizing online replacement of the activated carbon granules 35 without stopping the machine for disassembly and replacement, thus improving the treatment efficiency of waste gas.

[0041] The top heights of the first separator 31, the second separator 32, and the third separator 33 increase sequentially, which facilitates the material guiding assembly 5 to accurately guide the activated carbon particles 35 into the first adsorption chamber or the second adsorption chamber.

[0042] Preferably, sensors are installed at the top and bottom of the first adsorption chamber and the second adsorption chamber respectively to monitor the height position of the activated carbon particles 35, so as to accurately identify whether the failed activated carbon particles 35 have been completely discharged and whether the new activated carbon particles 35 have been replenished.

[0043] Preferably, an exhaust gas sensor is installed in the exhaust pipe 26 to monitor whether the discharged exhaust gas meets the treatment requirements, and the activated carbon granules 35 are replaced in time if the requirements are not met.

[0044] In a preferred embodiment, such as Figure 1 As shown, the bottom of the discharge chamber 22 is semi-circular or semi-elliptical, and the discharge pipe 23 is located at the lowest point of the discharge chamber 22, ensuring that the activated carbon particles 35 are smoothly discharged through the discharge pipe 23.

[0045] In a preferred embodiment, such as Figure 1As shown, a plurality of first support rods 310 are evenly distributed circumferentially between the first separator 31 and the second separator 32 to ensure the structural strength of the first adsorption chamber; a plurality of second support rods are evenly distributed circumferentially between the second separator 32 and the third separator 33 to ensure the structural strength of the second adsorption chamber.

[0046] In a preferred embodiment, such as Figure 1 As shown, a fixing frame 312 is provided between the third separator 33 and the tank 2, which improves the structural stability of the adsorption assembly 3.

[0047] In a preferred embodiment, such as Figure 1 As shown, a flow regulating valve 27 is installed on the air inlet pipe 25. When the activated carbon particles 35 are replaced, the flow rate of the petrochemical waste gas is reduced by the flow regulating valve 27 because the thickness of the activated carbon particle 35 adsorption layer is relatively reduced, so as to ensure the adsorption effect of the single adsorption layer.

[0048] In a preferred embodiment, such as Figure 1 As shown, the feeding assembly 4 includes a material tank 41 fixedly mounted on the bracket 1 above the tank body 2. The bottom of the material tank 41 is connected to the top of the tank body 2 through a feeding pipe 42. A feeding valve 43 is provided on the feeding pipe 42. A feeding port 44 is provided on the top of the material tank 41. A material cover 46 is provided on the feeding port 44.

[0049] In this embodiment, the material cover 46 is opened, and activated carbon granules 35 can be injected into the material tank 41 through the feeding port 44 for later use. When replacing the activated carbon granules 35, the feeding valve 43 is opened, and the activated carbon granules 35 enter the tank 2 through the feeding pipe 42 and then enter the adsorption assembly 3. After the replacement of the activated carbon granules 35 is completed, the feeding valve 43 is closed, realizing automatic replacement of activated carbon granules 35 and making the replacement of activated carbon granules 35 convenient.

[0050] In a preferred embodiment, such as Figure 1 As shown, a pressure relief valve 46 is provided at the top of the material tank 41 to regulate the pressure inside the material tank 41 and ensure that the activated carbon particles 35 are smoothly output through the feed pipe 42; the bottom of the material tank 41 is inverted cone-shaped to prevent the activated carbon particles 35 from accumulating on the bottom edge of the material tank 41 for a long time and becoming ineffective.

[0051] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the material guiding assembly 5 includes a support plate 51 fixedly installed inside the first dividing cylinder 31 near the top. A lifting cylinder 52 is fixedly installed on the top surface of the support plate 51. A support 53 is fixedly connected to the top of the lifting cylinder 52. A guide cone 54 is fixedly installed on the top of the support 53. The outer diameter of the support 53 is clearance-fitted with the inner diameter of the top of the first dividing cylinder 31. The height of the support 53 is greater than the lifting stroke of the lifting cylinder 52. The outer diameter of the bottom end of the guide cone 54 is equal to the outer diameter of the top of the first dividing cylinder 31.

[0052] In this embodiment, the guide cone 54 is located directly below the feed pipe 42. When the guide cone 54 is placed at the top of the first separator 31, the activated carbon particles 35 falling through the feed pipe 42 fall onto the guide cone 54 and slide down the inclined surface of the guide cone 54 into the first adsorption chamber.

[0053] like Figure 2 As shown, after the lifting cylinder 52 drives the guide cone 54 to rise, the activated carbon particles 35 falling through the feeding pipe 42 are guided by the guide cone 54 and enter the second adsorption chamber. At this time, the support 53 remains embedded in the top of the first separator cylinder 31 to prevent the activated carbon particles 35 from entering the interior of the top of the first separator cylinder 31. Even if a small amount of activated carbon particles 35 enters the first adsorption chamber, it will not have any impact.

[0054] In a preferred embodiment, such as Figure 1 As shown, the apex angle of the guide cone 54 is 130°-160°, which provides good guidance and deceleration effects.

[0055] In a preferred embodiment, such as Figure 1 As shown, the outer diameter of the top of the first separator 31 gradually decreases from bottom to top, the outer diameter of the top of the second separator 32 gradually decreases from bottom to top, and the outer diameter of the top of the third separator 33 gradually decreases from bottom to top, ensuring that the activated carbon particles 35 guided by the feeding assembly 5 are smoothly injected into the first adsorption chamber or the second adsorption chamber.
