Description

Technical Field

[0001] This invention relates to the field of gas recovery and treatment technology, specifically to a safe gas recovery and treatment device for chemical production. Background Technology

[0002] Chemical production processes generate large amounts of waste gas containing volatile organic compounds, toxic and harmful gases, and dust. This type of waste gas is not only an important precursor to urban haze and photochemical smog, but also poses toxic, irritating, and even carcinogenic risks to human health. As the core equipment for gas recovery and treatment in chemical production, the spray tower achieves gas purification and resource recovery by dissolving pollutants in the waste gas or causing chemical reactions through the contact and reaction of gas and liquid phases within the tower.

[0003] In the prior art, Chinese Patent No. CN221815757U discloses a chemical waste gas recovery and treatment device, including a water storage tank; a purification tower is set on one side of the upper end of the water storage tank, the lower end of the purification tower has a metal adsorption layer, a spray plate is set on the upper part of the purification tower, and the bottom of the spray plate has densely distributed nozzles. A water conveying component is set on the outside of the purification tower to guide the water in the water storage tank to the spray plate, and a sieve assembly is set on the upper part of the spray plate. When the waste gas after being treated by the decomposition box enters the purification tower, the spray plate, with the cooperation of the water pump and the water conveying pipe, can use the nozzles to thoroughly wash the incoming waste gas, so that the dust and other solid particles in the waste gas are washed into the metal adsorption layer for sieve purification. At the same time, the washed gas will naturally float upward, and the fine filter screen can filter out a small amount of fine particles in the gas, while the activated carbon layer can deeply adsorb odor molecules and dust in the gas, so that the waste gas is effectively treated.

[0004] For example, in the prior art, Chinese patent CN218485591U discloses a chemical waste gas recovery and treatment device, including: an exhaust pipe, a gas-liquid separation device, a waste gas treatment device, and a sewage discharge valve. The exhaust pipe is connected to the gas-liquid separation device, the gas-liquid separation device is connected to the waste gas treatment device, and the sewage discharge valve is connected to the exhaust pipe. The waste gas treatment device includes: a drying box, a waste gas processor shell, a waste gas treatment chamber, a rotating shaft, a filter screen, activated carbon, an air inlet door, an exhaust port, a push-suction filter plug, a one-way suction tip, an auxiliary moving frame, and a cylinder. By adding a gas-liquid separation device and a waste gas treatment device, rapid treatment of chemical waste gas and recycling and reuse of waste liquid can be achieved, improving the working environment for employees and saving resources.

[0005] Based on the above information, existing chemical gas recovery and treatment devices suffer from limitations in practical applications. The fixed installation of nozzles prevents adjustment of the spray range, leading to insufficient contact between some gases and the washing liquid, resulting in low gas-liquid mass transfer efficiency and ultimately affecting gas purification. Furthermore, the static structure of the internal filter media makes it prone to agglomeration, solidification, or blockage during long-term operation, increasing resistance to waste gas flow, reducing treatment efficiency, and posing a potential threat to environmental safety. Therefore, we propose a safer gas recovery and treatment mechanism for chemical production. Summary of the Invention

[0006] The purpose of this invention is to provide a safe gas recovery and treatment device for chemical production, in order to solve the problems mentioned in the background art. In practical applications, the existing chemical gas recovery and treatment devices use fixed installation of nozzles, which makes it impossible to adjust the spray range. This results in some gases not being able to fully contact the washing liquid, leading to low gas-liquid mass transfer efficiency and ultimately affecting the gas purification effect. Furthermore, the internal filter packing layer of the device has a static structure, which is prone to agglomeration, solidification, or blockage during long-term operation, causing increased resistance to waste gas flow, reduced treatment efficiency, and thus posing a potential threat to environmental safety.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a safe gas recovery and treatment mechanism for chemical production, comprising a treatment tower body, an air inlet assembly at the bottom of the treatment tower body, a spray assembly at the top of the treatment tower body, a packing disc inside the treatment tower body, the packing disc being filled with filter packing, a drain port at the bottom of the treatment tower body, and an exhaust port at the top of the treatment tower body, a mixing mechanism inside the treatment tower body for promoting gas-liquid mixing, the mixing mechanism including a rotating disc rotatably mounted on the inner wall of the treatment tower body, the inner wall of the rotating disc being provided with a guide plate and a baffle plate, and an anti-caking mechanism inside the packing disc for preventing the filter packing from caking and clogging.

The spray assembly includes a spray main pipe fixedly installed on the upper part of the treatment tower body, and spray branch pipes are rotatably connected to the side wall of the spray main pipe and are evenly distributed. Spray nozzles are evenly distributed at the bottom of the spray branch pipes.

[0009] Preferably, the mixing mechanism further includes a drive rod fixedly installed at the bottom of the rotating disk, and the bottom end of the drive rod is connected to the bottom of the processing tower body through a bearing. A drive motor is fixedly installed at the bottom of the processing tower body, and the output end of the drive motor is provided with a bevel gear set for driving the drive rod to rotate. The top of the rotating disk is provided with a lifting assembly for driving the spray branch pipe to swing.

[0010] Preferably, the packing disc is located between the rotating disc and the spray assembly, the guide plate is generally inclined and the guide plates are distributed at equal angles on the inner wall of the rotating disc to guide the gas to the packing disc, the baffle is generally Z-shaped bent and the baffles are distributed at equal intervals along the radial direction of the rotating disc, and the baffles are located at the top of the guide plate.

[0011] Preferably, the lifting assembly includes a top block disposed on the top of the rotating disk, a lifting rod slidably installed inside the packing disk, a driving rack at the top of the lifting rod, a return spring sleeved at the bottom of the lifting rod, a spiral pattern at the lower part of the lifting rod, an external toothed ring on the outer wall of the spray branch pipe, a limiting frame at the top of the packing disk, and the lifting rod slidably connected to the limiting frame.

[0012] Preferably, the lifting rod is perpendicular to the packing disc, and the lifting rod has an inverted T-shaped cross-section. A lifting rod is provided between every two sets of spray branch pipes. The outer walls of both sides of the drive rack are provided with teeth, and the teeth on both sides of the drive rack mesh with the adjacent outer gear rings. The end of the top block is designed with a slope, and the slope of the top block contacts the bottom of the lifting rod. The top block and the lifting rod are arranged in a one-to-one correspondence. The top end of the return spring abuts against the bottom of the packing disc, and the bottom end of the return spring abuts against the bottom of the lifting rod.

[0013] Preferably, the anti-caking mechanism includes a spiral sleeve rotatably installed at the bottom of the packing disc, and the outer wall of the spiral sleeve is provided with an agitator, and the end of the agitator is provided with an agitator rod, and the top of the packing disc is provided with a striking component.

[0014] Preferably, the stirring blocks are evenly distributed on the outer wall of the spiral sleeve, and the side walls of the stirring blocks are designed with an inclined surface. The stirring rod is set perpendicular to the stirring blocks, and the spiral sleeve and the lifting rod are connected by a spiral thread.

[0015] Preferably, the striking assembly includes a striking block fixedly installed on the outer wall of the lifting rod, and a transmission column is provided at the center of the packing disc, with both ends of the transmission column connected to the bottom of the limiting frame and the bottom of the packing disc, respectively. In the striking state, the bottom of the striking block contacts the top of the limiting frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This safe chemical production gas recovery and treatment device, through the linkage design of the mixing mechanism and the spray assembly, realizes the dynamic swing of the spray branch pipe. Combined with the evenly distributed spray heads, it expands the spray coverage of the washing liquid. At the same time, the rotating disk drives the guide plate and baffle plate to stir the airflow, promote the full contact and turbulent mixing of the gas and liquid phases, greatly improve the mass transfer efficiency, and ensure that the pollutants in the waste gas are efficiently absorbed and purified. It solves the problems of limited spray range and insufficient gas-liquid contact of traditional fixed nozzles, and improves the stability and safety of the treatment process.

[0017] 2. By setting up an anti-caking mechanism, the spiral sleeve rotates with the lifting rod, driving the stirring block and stirring rod to stir and disperse the filter packing in all directions. At the same time, the striking component periodically strikes the packing disc, effectively preventing the filter packing from clumping, solidifying and clogging during long-term operation, maintaining the permeability of the packing layer, reducing the resistance to exhaust gas flow, ensuring the long-term stable operation of the device, and avoiding the reduction of treatment efficiency due to packing blockage.

[0018] 3. By linking a single drive motor with the mixing mechanism, spray oscillation, anti-caking agitation, and knocking functions, multiple actions are coordinated, simplifying the equipment transmission structure and reducing energy consumption and maintenance costs. At the same time, the air intake assembly adopts a multi-branch pipe and multi-nozzle design, which makes the exhaust gas evenly distributed into the treatment tower. With the guiding effect of the baffle, local airflow concentration is avoided, improving the stability and safety of the treatment process and reducing the risk of leakage of toxic and harmful gases.

[0019] 4. The lifting component and the return spring work together to realize the reciprocating swing of the spray branch pipe and the periodic striking of the striking component. The spiral transmission ensures that the stirring action and the lifting action are precisely synchronized. The overall structure is compact and the action coordination is strong. There is no need to add an additional drive device, which reduces the equipment manufacturing cost. Moreover, each component adopts a modular design, which is easy to disassemble and maintain, and improves the ease of operation.

[0020] 5. Thorough gas-liquid mixing and efficient absorption significantly improve the removal rate of pollutants in waste gas, reducing the pollution of the environment and the harm to human health caused by the emission of toxic and harmful gases; at the same time, the anti-caking mechanism of the filter packing extends its service life, and the washing liquid is recycled and reused through the drain port, realizing resource recycling, which is in line with the concept of energy conservation and environmental protection, and has both environmental and economic benefits.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figures 1-8 The present invention provides the following technical solution: a safe gas recovery and treatment mechanism for chemical production, comprising a treatment tower body 1, an air inlet assembly at the bottom of the treatment tower body 1, a spray assembly at the top of the treatment tower body 1, a packing disc 11 inside the treatment tower body 1, the packing disc 11 being filled with filter packing, a drain port 5 at the bottom of the treatment tower body 1, an exhaust port 6 at the top of the treatment tower body 1, and a mixing mechanism for promoting gas-liquid mixing inside the treatment tower body 1, the mixing mechanism comprising a rotating disc 12 rotatably mounted on the inner wall of the treatment tower body 1, and a guide plate 13 and a baffle plate 14 on the inner wall of the rotating disc 12.

[0025] like Figures 1-4 as well as Figure 7As shown, the air intake assembly consists of an air intake main pipe 2, an air intake branch pipe 3, and an air intake nozzle 4. The air intake branch pipes 3 are evenly distributed on the side wall of the air intake main pipe 2, and the air intake nozzles 4 are evenly distributed on the top of the air intake branch pipes 3. The spray assembly includes a spray main pipe 7 fixedly installed on the upper part of the treatment tower body 1. The side wall of the spray main pipe 7 is rotatably connected to spray branch pipes 8 that are evenly distributed, and the bottom of the spray branch pipes 8 is provided with spray nozzles 9 that are evenly distributed.

[0026] like Figures 1-8 As shown, the mixing mechanism also includes a drive rod 15 fixedly installed at the bottom of the rotating disk 12, and the bottom end of the drive rod 15 is connected to the bottom of the processing tower body 1 through a bearing. A drive motor 17 is fixedly installed at the bottom of the processing tower body 1, and the output end of the drive motor 17 is provided with a bevel gear set 16 for driving the drive rod 15 to rotate. The top of the rotating disk 12 is provided with a lifting assembly for driving the spray branch pipe 8 to swing. The packing disk 11 is located between the rotating disk 12 and the spray assembly. The guide plate 13 is generally inclined and is distributed at equal angles on the inner wall of the rotating disk 12 to guide the gas to the packing disk 11. The baffle plate 14 is generally Z-shaped bent and is distributed at equal intervals along the radial direction of the rotating disk 12. The baffle plate 14 is located on top of the guide plate 13.

[0027] like Figures 2-8 As shown, the lifting assembly includes a top block 25 disposed on the top of the rotating disk 12, a lifting rod 18 slidably mounted inside the packing disk 11, a driving rack 20 at the top of the lifting rod 18, a return spring 21 sleeved at the bottom of the lifting rod 18, a spiral pattern 19 at the lower part of the lifting rod 18, an external gear ring 10 on the outer wall of the spray branch pipe 8, a limiting frame 27 at the top of the packing disk 11, and the lifting rod 18 slidably connected to the limiting frame 27; the lifting rod 18 is perpendicular to the packing disk 11, and the lifting rod 18 is slidably mounted on the top of the packing disk 11. The cross-section of the 8 is designed in an inverted T shape, and a lifting rod 18 is provided between every two sets of spray branch pipes 8. The outer walls on both sides of the drive rack 20 are provided with teeth, and the teeth on both sides of the drive rack 20 respectively mesh with the adjacent outer gear ring 10. The end of the top block 25 is designed with a bevel, and the bevel of the top block 25 contacts the bottom of the lifting rod 18. The top block 25 and the lifting rod 18 are set in a one-to-one correspondence. The top of the return spring 21 abuts against the bottom of the packing disc 11, and the bottom of the return spring 21 abuts against the bottom of the lifting rod 18.

[0028] Chemical waste gas is diverted from the main inlet pipe 2 to the branch inlet pipes 3, and released into the main body 1 of the treatment tower through evenly distributed inlet nozzles 4, achieving uniform gas distribution. At the same time, the main spray pipe 7 delivers washing liquid to the branch spray pipes 8, which is sprayed in a mist form through the spray nozzles 9. When the rotating disk 12 rotates, the inclined guide plate 13 on its inner wall guides and agitates the rising airflow, evenly guiding the waste gas towards the packing disk 11. The Z-shaped baffle 14 further divides the airflow, making the airflow turbulent. Simultaneously, the inclined top block 25 at the top of the rotating disk 12 rotates synchronously, periodically contacting the bottom of the lifting rod 18 and pushing the lifting rod 18 to slide upward along the limiting frame 27. When the powerful return spring 21 is compressed, the drive rack 20 at the top of the lifting rod 18 drives the outer gear ring 10 of the adjacent spray branch pipe 8 to rotate through the teeth on both sides. The up and down movement of the lifting rod 18 causes the spray branch pipe 8 to swing back and forth around the spray main pipe 7, thereby expanding the coverage area of ​​the washing liquid spray. When the top block 25 rotates and disengages from the lifting rod 18, the powerful return spring 21 elastically resets and pushes the lifting rod 18 down. The drive rack 20 drives the spray branch pipe 8 to reset in the opposite direction. This cycle realizes the dynamic swing of the spray branch pipe 8. Combined with the stirring effect of the guide plate 13 and the baffle plate 14 on the airflow, it greatly increases the contact area and turbulence intensity of the gas and liquid phases, and promotes the efficient dissolution and reaction of pollutants.

[0029] Example 2: Please refer to Figures 1-10 Based on Embodiment 1, an anti-caking mechanism is also disclosed, the specific structure of which is as follows: The stuffing disc 11 is provided with an anti-caking mechanism for preventing filter packing from caking and clogging. The anti-caking mechanism includes a spiral sleeve 22 rotatably installed at the bottom of the stuffing disc 11, and an agitator 23 is provided on the outer wall of the spiral sleeve 22. An agitator 24 is provided at the end of the agitator 23. A knocking component is provided on the top of the stuffing disc 11.

[0030] like Figures 2-10 As shown, the stirring blocks 23 are evenly distributed on the outer wall of the spiral sleeve, and the side wall of the stirring blocks 23 is designed with an inclined surface. The stirring rod 24 is set perpendicular to the stirring blocks 23. The spiral sleeve and the lifting rod 18 are connected by a spiral thread 19.

[0031] like Figures 8-10 As shown, the striking assembly includes a striking block 26 fixedly installed on the outer wall of the lifting rod 18. A transmission column 28 is provided at the center of the filling plate 11, and the two ends of the transmission column 28 are respectively connected to the bottom of the limiting frame 27 and the bottom of the filling plate 11. In the striking state, the bottom of the striking block 26 contacts the top of the limiting frame 27.

[0032] The anti-caking mechanism and the mixing mechanism are linked by the lifting rod 18. When the lifting rod 18 is pushed vertically up and down along the packing disc 11 by the top block 25, the spiral thread 19 at its lower part engages with the inner thread of the spiral sleeve 22. Since the spiral sleeve 22 and the packing disc 11 are rotatably connected, it will not follow the lifting rod 18 in the vertical direction to reciprocate. This causes the spiral sleeve 22 to rotate at the bottom of the packing disc 11. When the spiral sleeve 22 rotates, the inclined stirring blocks 23 evenly distributed on its outer wall rotate synchronously, forming a lateral pushing and dispersing of the filter packing in the packing disc 11. The stirring rod 24 at the end of the stirring block 23 penetrates into the packing layer to further break up the packing agglomeration. The upward movement of the lifting rod 18 prevents clumping and solidification. Simultaneously, during the lifting process, the striking block 26 fixed to its outer wall moves downwards. When the lifting rod 18 returns to its lowest position, the bottom of the striking block 26 collides with the top of the limiting frame 27. The resulting vibration is transmitted through the limiting frame 27 and the transmission column 28 to the entire packing disc 11, causing slight vibration in the packing layer. This shakes off impurities and condensates adhering to the packing surface, clearing the gaps between the packing layers. Through the combined effects of rotational agitation and vibration, the permeability of the filter packing layer is continuously maintained, effectively preventing packing caking and blockage, reducing exhaust gas flow resistance, ensuring long-term stable operation of the device, and avoiding efficiency reduction due to packing blockage.
