Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, specifically a waste gas treatment device for pharmaceutical workshops. Background Technology

[0002] Pharmaceutical workshops generate large amounts of waste gas containing volatile organic compounds (VOCs), dust, and odor components during the production process. If this waste gas is discharged directly without effective treatment, it will cause serious harm to the environment and human health. Currently, the waste gas treatment method usually adopts the adsorption method. Among them, the adsorption method often uses materials such as activated carbon to capture organic matter in the waste gas. However, existing devices still suffer from problems such as low treatment efficiency, high energy consumption, and frequent replacement of adsorption materials in practical applications, making it difficult to meet the demand for efficient, stable, and economical waste gas treatment. In particular, when using high-efficiency activated carbon as the adsorption medium, although it can improve the adsorption capacity, the traditional large-space honeycomb structure is prone to uneven airflow distribution and insufficient adsorption, which limits its performance. Therefore, there is an urgent need to develop a waste gas treatment device for pharmaceutical workshops. Summary of the Invention

[0003] The purpose of this invention is to provide a waste gas treatment device for pharmaceutical workshops, so as to solve the problems of uneven airflow and insufficient adsorption caused by the activated carbon adsorption structure in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A waste gas treatment device for a pharmaceutical workshop includes a separation device, an adsorption device, and a spraying device, wherein the spraying device is connected to a pumping device. The adsorption device includes an adsorption tube and several adsorption groups, the adsorption tube being connected to the adsorption groups; the several adsorption groups are arranged vertically, and a rotating fan is provided between two adjacent adsorption groups, the rotating fan being connected to the adsorption tube, and the rotating fan being driven by a driving device. The spraying device includes a spray pipe, several spray rings and a compressor. The spray pipe is connected to the adsorption pipe, the spray rings are connected to the spray pipe, the compressor is connected to the spray rings, and the spray pipe is connected to the separation device. A conveying device is provided between the adsorption pipe and the spray pipe. The conveying device includes a conveying pipe and a diversion group. The two ends of the conveying pipe are respectively connected to the adsorption pipe and the spray pipe.

[0005] After the waste gas enters the adsorption device, it passes through several adsorption groups in sequence through the adsorption tube. Under the adsorption action of the adsorption groups, the impurities in the waste gas are adsorbed and treated. When the waste gas passes through a group of adsorption groups and is conveyed to the next group, the drive device drives the rotating fan to rotate. The rotation of the rotating fan can speed up the conveying speed of the waste gas, thereby extracting the waste gas conveyed by the previous adsorption group and pushing the waste gas conveyed by the next adsorption group, thus increasing the conveying speed of the waste gas. The waste gas treated by the adsorption device is transported to the conveying pipe through the adsorption pipe. Then the waste gas moves along the conveying pipe to the spray pipe. During the movement, the waste gas will flow through the diversion group. At this time, the waste gas will be diverted by the diversion group. Part of the waste gas will be transported back to the adsorption pipe for adsorption treatment again through the diversion group, while the other part of the waste gas will be transported to the spray pipe. The adsorbed waste gas is transported to the spraying device. First, the waste gas enters the spray pipe and is transported along the spray pipe to the spray ring. When the waste gas enters the space between the spray ring and the compressor, the spray ring sprays atomized liquid onto the waste gas. The atomized liquid then sprays and mixes the waste gas, thereby further treating the waste gas. The waste gas treated by spraying is transported to the separation device through the spraying device, where the atomized liquid and the waste gas are separated.

[0006] Preferably, the adsorption group consists of several adsorption tanks, which are arranged around the axis of the adsorption tube. Adsorption material is provided in each adsorption tank, and the adsorption material divides the space of the adsorption tank.

[0007] After the waste gas enters the adsorption pipe, it first flows through the conveying top cover and then flows to several adsorption groups. Before entering the conveying pipe, the waste gas needs to flow through each adsorption group, so that the waste gas enters the adsorption tank through the adsorption pipe, passes through the adsorption material in the adsorption tank, and then enters the adsorption pipe again after passing through the adsorption material, and is conveyed to the next adsorption group. Thus, through multiple adsorption treatments, the impurities in the waste gas are adsorbed, thereby achieving the effect of waste gas treatment.

[0008] Preferably, a plurality of spray rings are arranged vertically along the axis of the spray pipe, and a plurality of protrusions are provided on the inner side of the spray rings. Each protrusion is provided with a plurality of spray nozzles. The spray nozzles are connected to a pumping device through a pipe. A drive shaft is provided at the bottom of the compression body. The compression body is rotatably connected to the drive shaft, and the drive shaft is connected to a power device.

[0009] After the exhaust gas enters the spray pipe, the controller starts the pumping device, which delivers the spray liquid through the pipeline to the spray nozzle. The spray liquid is sprayed out through the spray nozzle and forms an atomized liquid. The compressor rotates around the spray ring, which compresses the space between the compressor and the spray ring. As a result, the space in which the atomized liquid is sprayed becomes smaller, thus achieving a higher spraying effect with a smaller atomization amount, and ensuring that the atomized liquid and exhaust gas are fully mixed.

[0010] Preferably, a blocking block is provided on one side of the compression body, the compression body is rotatably connected to the blocking block, the blocking block is crescent-shaped, the blocking block is also connected to the drive shaft, and cover plates are provided at the upper and lower ends of the spray ring, the cover plates are connected to the blocking block, and the blocking block and cover plates are respectively rotatably and sealingly connected to the spray ring.

[0011] During the rotation of the drive shaft, both the compressor and the blocking block rotate. The blocking block revolves around the axis of the spray ring. Simultaneously, the blocking block rotates the cover plate, causing it to also revolve around the axis of the spray ring. As the cover plate rotates, the crescent-shaped blocking block creates a conveying channel with the spray ring. Thus, the exhaust gas entering the spray pipe via the conveying device can only enter the space between the compressor and the spray ring through the crescent-shaped opening of the blocking block. This compresses the exhaust gas's conveying path, allowing the exhaust gas and atomized liquid to be sprayed and washed within a smaller space. This saves atomized liquid while achieving a better spraying effect, further improving the quality of exhaust gas treatment.

[0012] Preferably, the spray ring is toothed, the compression body is gear-shaped, and the compression body meshes with the spray ring.

[0013] When the drive shaft rotates under the action of the power unit, it drives the compressor to rotate. The compressor revolves around the axis of the spray ring. At this time, since the compressor and the spray ring are in a meshing state, the compressor will rotate on its own axis under the influence of the spray ring during the revolution. This causes the protruding teeth of the compressor to extend into the space between two adjacent protrusions. After the protruding teeth extend in, the space between the two adjacent protrusions is compressed. This causes the exhaust gas flowing through this space to move towards the side closer to the spray nozzle under the action of the protruding teeth. This results in a shorter spraying distance of the atomized liquid sprayed from the spray nozzle, thus achieving the maximum spraying effect on the exhaust gas in a limited space, thereby improving the quality of exhaust gas treatment.

[0014] Preferably, the diversion group consists of a large conveying port, a small conveying port, and a conveying top cover. The large conveying port is located on the side of the conveying pipe near the spray pipe, the small conveying port is located at the connection between the conveying pipe and the spray pipe, the conveying top cover is connected to the large conveying port, a conveying fan is provided inside the large conveying port, the conveying fan is rotatably connected to the large conveying port, a power component is provided inside the conveying top cover, the power component is connected to the conveying fan blades, and the side of the large conveying port near the conveying top cover is connected to the adsorption pipe.

[0015] During the process of conveying the exhaust gas through the conveying pipe, the controller starts the power component, which then drives the conveying fan blades to rotate. The rotation of the conveying fan blades generates a certain suction force, so that when the exhaust gas flows through the large conveying port, the exhaust gas is captured by the conveying fan blades. Then, a part of the exhaust gas is conveyed to the large conveying port, and then conveyed to the top cover of the conveying pipe. Finally, under the driving action of the conveying fan blades, it re-enters the adsorption pipe and flows through the adsorption group again for further adsorption treatment. The exhaust gas, which is not affected by the conveyor blades, continues to move along the conveyor pipe and is conveyed to the side near the small conveyor port, and then conveyed to the spray pipe for spray washing treatment.

[0016] Preferably, the diameter of the large conveying port is larger than the diameter of the small conveying port.

[0017] Because the diameter of the large conveying port is larger than that of the small conveying port, the exhaust gas will first encounter the large conveying port when flowing in the conveying pipe. In addition, the rotation of the conveying fan blades will cause a larger portion of the exhaust gas to flow towards the large conveying port. At the same time, the unadsorbed impurities in the exhaust gas will also be attracted, causing the impurities to be transported back to the adsorption pipe for further adsorption. Meanwhile, the other part of the exhaust gas is transported to the spray pipe through the small conveying port.

[0018] Preferably, the drive shaft of the compression body extends towards the side near the small conveying port, and a suction fan is provided on the side of the drive shaft near the small conveying port; the rotation direction of the conveying fan blades is opposite to the rotation direction of the suction fan.

[0019] While the conveyor fan blades are rotating, the drive shaft also drives the suction fan to rotate. The suction fan draws the exhaust gas in the conveyor pipe to the spray pipe, so that the conveyor fan blades and the suction fan work together to divert the exhaust gas in the conveyor pipe. This allows the smaller flow of exhaust gas to be fully sprayed and washed in the spray pipe, thereby improving the quality of the exhaust gas after subsequent spraying treatment and achieving the effect of treating small amounts of gas multiple times. Because the rotation direction of the conveying fan blades is opposite to that of the suction fan, the exhaust gas in the conveying pipe will flow to the large conveying port and the small conveying port respectively, thus achieving the effect of diversion treatment. Part of the exhaust gas is subjected to adsorption treatment again, while the other part of the exhaust gas is subjected to spray treatment, thereby avoiding the problem of a large amount of exhaust gas being transported into the spray pipe, resulting in poor spraying effect, and thus improving the quality of exhaust gas treatment.

[0020] Compared with the prior art, the beneficial effects of the present invention are: 1. The adsorption device employs multiple vertically arranged adsorption groups, each consisting of multiple adsorption tanks arranged around the axis of the adsorption tube. The adsorption tanks are filled with high-efficiency activated carbon material. During the multiple flow processes, the waste gas comes into full contact with the activated carbon, significantly improving the adsorption capacity for organic pollutants and odors. At the same time, the rotating fans set between adjacent adsorption groups rotate under the drive of the drive device, which not only accelerates the transport of waste gas, but also realizes the extraction and propulsion of the airflow between the adsorption groups, improving the uniformity of gas flow and adsorption efficiency.

[0021] 2. The spray device is equipped with multiple spray rings and a compressor. The protruding part on the inner side of the spray ring is equipped with a spray nozzle, which is connected to the pumping device. The spray liquid is atomized through the spray nozzle and mixed with the exhaust gas. The compressor revolves around the spray ring and rotates on its own axis under the drive of the power device. The structure that meshes with the spray ring effectively compresses the spray space. The atomized liquid fully contacts the exhaust gas in the limited space, which significantly improves the spray washing effect and saves the amount of spray liquid used. At the same time, a crescent-shaped blocking block and a cover plate are provided on one side of the compressor to form a sealed spray channel. The exhaust gas can only enter the spray area through the crescent-shaped notch of the blocking block, further compressing the airflow path and enhancing the gas-liquid mixing effect.

[0022] 3. A conveying device is installed between the adsorption pipe and the spray pipe, including a conveying pipe and a diversion group. The diversion group consists of a large conveying port, a small conveying port, and a conveying top cover. A conveying fan is installed in the large conveying port, which can introduce some of the waste gas back into the adsorption pipe for secondary adsorption, thereby improving the adsorption utilization rate. At the same time, the drive shaft of the compressor extends to the vicinity of the small conveying port and is equipped with an suction fan, which forms an airflow in the opposite direction to the conveying fan, further realizing the diversion and circulation treatment of waste gas, ensuring that the amount of waste gas entering the spray pipe is moderate and the concentration is uniform, and avoiding overload of the spray system.

[0028] In one specific embodiment of the present invention, the spray ring 22 is toothed, the compression body 23 is gear-shaped, and the compression body 23 meshes with the spray ring 22.

[0029] In one specific embodiment of the present invention, a blocking block 24 is provided on one side of the compression body 23, the compression body 23 is rotatably connected to the blocking block 24, the blocking block 24 is crescent-shaped, the blocking block 24 is also connected to the drive shaft, and cover plates 25 are provided at the upper and lower ends of the spray ring 22, the cover plates 25 are connected to the blocking block 24, and the blocking block 24 and the cover plates 25 are respectively rotatably and sealingly connected to the spray ring 22.

[0030] In one specific embodiment of the present invention, a conveying device 3 is provided between the adsorption pipe 11 and the spray pipe 21. The conveying device 3 includes a conveying pipe 31 and a diversion group 32. The two ends of the conveying pipe 31 are respectively connected to the adsorption pipe 11 and the spray pipe 21.

[0031] In one specific embodiment of the present invention, the diversion group 32 consists of a large conveying port 33, a small conveying port 34, and a conveying top cover 35. The large conveying port 33 is located on the side of the conveying pipe 31 near the spray pipe 21.

[0032] In one specific embodiment of the present invention, the diameter of the large conveying port 33 is larger than the diameter of the small conveying port 34.

[0033] In one specific embodiment of the present invention, the drive shaft of the compression body 23 extends along the side close to the small conveying port 34, and a suction fan 37 is provided on the side of the drive shaft close to the small conveying port 34.

[0034] In one specific embodiment of the present invention, the rotation direction of the conveying fan blade 36 is opposite to the rotation direction of the suction fan 37.

[0035] Working principle of the invention: After the waste gas enters the adsorption device 1, it passes through several adsorption groups 12 in sequence through the adsorption tube 11. Under the adsorption action of the adsorption groups 12, the impurities in the waste gas are adsorbed and treated. When the waste gas passes through a group of adsorption groups 12 and is conveyed to the next adsorption group 12, the drive device drives the rotating fan 13 to rotate. The rotation of the rotating fan 13 can speed up the conveying speed of the waste gas, thereby extracting the waste gas conveyed by the previous adsorption group 12 and pushing the waste gas conveyed by the next adsorption group 12, thereby increasing the conveying speed of the waste gas. After the waste gas enters the adsorption pipe 11, it first flows through the conveying top cover 35 and then flows through the conveying top cover 35 to several adsorption groups 12. Before entering the conveying pipe 31, the waste gas needs to flow through each adsorption group 12, so that the waste gas enters the adsorption tank 14 through the adsorption pipe 11 and passes through the adsorption material 15 in the adsorption tank 14. After passing through the adsorption material 15, it re-enters the adsorption pipe 11 and is conveyed to the next adsorption group 12. Thus, through multiple adsorption treatments, the impurities in the waste gas are adsorbed. The waste gas treated by the adsorption device 1 is transported to the conveying pipe 31 through the adsorption pipe 11. Then the waste gas moves along the conveying pipe 31 to the spray pipe 21. During the movement, the waste gas will flow through the diversion group 32. At this time, the waste gas will be diverted by the diversion group 32. Part of the waste gas will be transported back to the adsorption pipe 11 through the diversion group 32 for another adsorption treatment, while the other part of the waste gas will be transported to the spray pipe 21. During the process of conveying the exhaust gas through the conveying pipe 31, the controller starts the power component, which then drives the conveying fan blade 36 to rotate. The rotation of the conveying fan blade 36 generates a certain suction force, so that when the exhaust gas flows through the large conveying port 33, the exhaust gas is captured by the conveying fan blade 36. Then, a part of the exhaust gas is conveyed to the large conveying port 33, and then conveyed from the large conveying port 33 to the conveying top cover 35. Finally, under the driving action of the conveying fan blade 36, it re-enters the adsorption pipe 11 and flows through the adsorption group 12 again for further adsorption treatment. The exhaust gas that is not affected by the conveying fan blades 36 continues to move along the conveying pipe 31 and is conveyed to the side near the small conveying port 34, and then conveyed to the spray pipe 21 for spray washing treatment through the small conveying port 34. Because the diameter of the large conveying port 33 is larger than that of the small conveying port 34, the exhaust gas will first encounter the large conveying port 33 when it flows in the conveying pipe 31. In addition, the rotation of the conveying fan blade 36 will cause a larger portion of the exhaust gas to flow toward the large conveying port 33. At the same time, the unadsorbed impurities in the exhaust gas will also be attracted, causing the impurities to be transported back to the adsorption pipe 11 for further adsorption along with the exhaust gas. The other part of the exhaust gas is transported to the spray pipe 21 through the small conveying port 34. As the conveying fan blades 36 rotate, the drive shaft also drives the suction fan 37 to rotate. The suction fan 37 draws the exhaust gas in the conveying pipe 31 towards the spray pipe 21, so that the conveying fan blades 36 and the suction fan 37 cooperate to divert the exhaust gas in the conveying pipe 31. At the same time, since the rotation direction of the conveying fan blades 36 is opposite to that of the suction fan 37, the exhaust gas in the conveying pipe 31 will flow to the large conveying port 33 and the small conveying port 34 respectively, thereby further achieving the effect of diversion treatment. After the exhaust gas enters the spray pipe 21, the controller controls the pumping device to start. The pumping device delivers the spray liquid through the pipeline to the spray nozzle 222. After the spray liquid is sprayed out through the spray nozzle 222, it forms an atomized liquid. Meanwhile, the compressor 23 rotates around the spray ring 22, which compresses the space between the compressor 23 and the spray ring 22, thereby reducing the space in which the atomized liquid is sprayed. During the rotation of the drive shaft, the drive shaft drives the compressor 23 and the blocking block 24 to rotate. The blocking block 24 only revolves around the axis of the spray ring 22. While the blocking block 24 is rotating, it drives the cover plate 25 to rotate, so that the cover plate 25 also revolves around the axis of the spray ring 22. As the cover plate 25 rotates, since the blocking block 24 is crescent-shaped, the crescent-shaped notch of the blocking block 24 forms a conveying channel with the spray ring 22. Thus, the exhaust gas entering the spray pipe 21 through the conveying device 3 can only enter the space between the compressor 23 and the spray ring 22 through the crescent-shaped notch of the blocking block 24. This compresses the conveying path of the exhaust gas, thereby enabling the exhaust gas and atomized liquid to be sprayed and washed in a smaller space, thus saving atomized liquid and achieving a better spraying effect. When the drive shaft rotates under the action of the power device, the drive shaft drives the compressor 23 to rotate. The compressor 23 revolves around the axis of the spray ring 22. At this time, since the compressor 23 and the spray ring 22 are in a meshing state, the compressor 23 will rotate on its own axis under the influence of the spray ring 22 during the revolution. This causes the protruding teeth of the compressor 23 to extend into the space between two adjacent protrusions 221. After the protruding teeth extend in, the space between two adjacent protrusions 221 is compressed. This causes the exhaust gas flowing through the space to move towards the side closer to the spray nozzle 222 under the action of the protruding teeth. This makes the distance of the atomized liquid sprayed from the spray nozzle 222 smaller, thus achieving the maximum spraying effect on the exhaust gas in a limited space. The waste gas treated by spraying is transported to the separation device through the spraying device 2, where the atomized liquid and waste gas are separated.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
