Description

Technical Field

[0001] This utility model relates to the field of petrochemical waste gas treatment technology, specifically a waste gas treatment device for petrochemical applications. Background Technology

[0002] The petrochemical industry generates a large amount of waste gas during production. This waste gas has a complex composition, mainly including hydrocarbons, hydrogen sulfide, nitrogen oxides, volatile organic compounds (VOCs), and particulate matter. These pollutants not only cause serious air pollution but may also harm human health, such as causing respiratory diseases and nervous system damage. Therefore, effective treatment of petrochemical waste gas is crucial and requires the use of waste gas treatment equipment.

[0003] According to the description in the patent application published on the Internet as a waste gas treatment device for petrochemical industry (authorization announcement number: CN219023667 U), "This utility model is a waste gas treatment device for petrochemical industry, including a filter barrel, an inlet valve and an outlet valve fixedly installed at both ends of the filter barrel, a number of support legs fixedly installed at the bottom of the filter barrel, a number of filter screen frames slidably installed on the side of the filter barrel, a slide rail fixedly installed at the top side of the filter barrel, a first motor, a second gear and a second motor slidably installed on the side of the slide rail, a first gear fixedly installed at the output end of the first motor, and a roller brush fixedly installed at the bottom of the second gear."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In the process of using this utility model, petrochemical waste gas is first introduced into the filter barrel through the inlet valve. The waste gas passes through the filter screen in the filter barrel to filter out toxic and harmful particulate matter. The filtered gas is then introduced into the next treatment stage through the outlet valve. However, in actual use, the size of the inlet is fixed during the air intake process, which prevents the device from adjusting according to the actual situation of waste gas emissions. Therefore, when the waste gas flow exceeds the device's designed processing capacity, the processing efficiency will be severely affected. Excessive waste gas flow may lead to insufficient treatment, and harmful substances in the waste gas may not be effectively removed. Therefore, it is necessary to improve the waste gas treatment device for petrochemical industry. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0030] Based on the existing technology, this device, due to the fixed size of the air inlet during the air intake process, cannot adjust according to the actual situation of the exhaust gas emission. Therefore, when the exhaust gas flow rate exceeds the device's design processing capacity, the processing efficiency will be severely affected. Excessive exhaust gas flow may lead to insufficient treatment, resulting in the ineffective removal of harmful substances from the exhaust gas. Please refer to [link / reference needed]. Figures 1-7 This utility model provides a technical solution: a waste gas treatment device for petrochemical industry, including a waste gas treatment device body 1, an air inlet pipe 2 fixedly connected to the left side of the waste gas treatment device body 1, an air inlet pipe 2 with an air dispersing mechanism 3 inside the air inlet pipe 2, a replacement mechanism 4 on the top of the waste gas treatment device body 1, an air outlet pipe 5 fixedly connected to the right side of the waste gas treatment device body 1, a filter plate 6 inserted inside the waste gas treatment device body 1, an activated carbon filter plate 7 inserted inside the waste gas treatment device body 1, and a molecular sieve plate 8 fixedly connected to the right side of the activated carbon filter plate 7;

[0031] The ventilation and dispersion mechanism 3 includes a ventilation component 31 and a dispersion component 32, with the dispersion component 32 disposed inside the main body 1 of the waste gas treatment device;

[0032] The ventilation assembly 31 includes a fixed sleeve 311, which is fixedly connected to the top of the air inlet pipe 2. A servo motor 312 is fixedly connected to the back of the fixed sleeve 311. A bevel gear 313 is fixedly connected to the output end of the servo motor 312.

This facilitates the adjustment of the air inlet and its size, thus preventing insufficient treatment of waste gas in petrochemical processes.

[0033] Furthermore, the second bevel gear 314 is rotatably connected to the inner side of the top of the fixed sleeve 311, and the rotating column 315 is rotatably connected to the inside of the air intake pipe 2, which facilitates the stable rotation of the rotating column 315.

[0034] Furthermore, the rotating sleeve 317 is rotatably connected inside the air intake pipe 2, and holes are opened at the corresponding positions of the rotating sleeve 317, the bevel gear 318 and the rotating column 315. The rotating sleeve 317 and the bevel gear 318 are rotatably connected outside the rotating column 315, so as to synchronously drive the two side baffles 316 and 319 to rotate.

[0035] Furthermore, the dispersion component 32 includes a connecting frame 321, which is fixedly connected to the top of the main body 1 of the exhaust gas treatment device. A second servo motor 322 is fixedly connected to the top of the connecting frame 321. A first gear 323 is fixedly connected to the output end of the second servo motor 322. A second gear 324 meshes with the back of the first gear 323. A guide plate 325 is fixedly connected to the bottom of the second gear 324. A partition 326 is fixedly connected inside the main body 1 of the exhaust gas treatment device to facilitate the flow guidance and dispersion.

[0036] Furthermore, the main body 1 of the exhaust gas treatment device has holes at the corresponding positions of the guide plate 325, and the guide plate 325 is rotatably connected in the holes, so as to facilitate the synchronous rotation of the guide plate 325. Example

[0037] Based on the existing technology, there is a need for easy removal of filter plate 6, activated carbon filter plate 7, and molecular sieve plate 8. Please refer to [link / reference needed]. Figure 7 Furthermore, in conjunction with Embodiment 1, it is further obtained that the replacement mechanism 4 includes a card holder 41, which is fixedly connected to the top of the main body 1 of the waste gas treatment device. A motor 42 is fixedly connected to the top of the card holder 41, and a rotating rod 43 is fixedly connected to the output end of the motor 42. A limiting post 44 is fixedly connected to the bottom of the rotating rod 43, and a card frame 45 is movably connected to the outside of the limiting post 44. A connecting plate 46 is fixedly connected to the front of the card frame 45, and a sealing sleeve 47 is fixedly connected to the bottom of the connecting plate 46. A sealing ring 48 is fitted onto the outside of the sealing sleeve 47, which facilitates the quick removal of the filter plate 6, activated carbon filter plate 7, and molecular sieve plate 8 inside the device after long-term use.

[0038] Furthermore, the activated carbon filter plate 7, molecular sieve plate 8, and filter plate 6 are all fixedly connected to the back of the sealing sleeve 47, and the main body 1 of the exhaust gas treatment device has a groove at the corresponding position of the sealing sleeve 47, and the sealing sleeve 47 is inserted into the groove. The card holder 41 and the card frame 45 have grooves at the corresponding positions, and the card frame 45 is slidably connected in the groove, so as to facilitate the synchronous movement of the sealing sleeve 47.

[0039] In actual operation, when the device is in use, firstly, waste gas is generated in the petrochemical process. According to the waste gas flow rate and velocity, the servo motor 312 is activated through the set ventilation and dispersion mechanism 3. The servo motor 312 drives the bevel gear 313 to rotate, which in turn drives the second bevel gear 314 and the second bevel gear to rotate synchronously. This causes the second bevel gear 314 to drive the rotating column 315 to rotate synchronously. At the same time, the third bevel gear 318 drives the rotating sleeve 317 to rotate synchronously. This causes the rotating column 315 and the rotating sleeve 317 to drive the first baffle 316 and the second baffle 319 to rotate in sequence. This causes the first baffle 316 and the second baffle 319 to rotate relative to each other, thereby controlling the size of the air inlet in the air inlet pipe 2 as needed. Then, the waste gas enters the main body 1 of the waste gas treatment device from the air inlet pipe 2. And through the forward and reverse servo motor 322, the servo motor 322 rotates synchronously with the second bevel gear 314 to rotate synchronously with the second bevel gear 315 ... The first gear 323 rotates, which in turn drives the second gear 324 to rotate, which in turn drives the guide plate 325 to rotate, thus controlling the guide plate 325 to swing left and right, which is conducive to gas dispersion. This allows the waste gas to pass through the filter plate 6, and then through the activated carbon filter plate 7 and the molecular sieve plate 8, thereby filtering out harmful substances in the waste gas and completing the waste gas treatment. Then, through the set replacement mechanism 4, the motor 3 42 is started, which drives the rotating rod 43 to rotate, and then the rotating rod 43 drives the limiting column 44 to rotate, which pushes the clamping frame 45 to move along the guide of the clamping frame 41, which in turn drives the connecting plate 46 to move, which in turn drives the sealing sleeve 47 to move, and then the sealing sleeve 47 drives the corresponding filter plate 6, activated carbon filter plate 7, and molecular sieve plate 8 to move, thus moving them out of the waste gas treatment device.
