Description

Technical Field

[0001] The present invention relates to the technical field of gas separation, and particularly to a gas separation device for air pollution. Background Art

[0002] With the rapid development of industrial production, a large amount of harmful gas emissions have caused serious pollution to the atmospheric environment, including volatile organic compounds, sulfur dioxide, nitrogen oxides, etc. These polluting organic gases not only affect air quality but also pose a threat to human health and the ecosystem.

[0003] In the existing treatment of organic waste gas, a cyclone tower is often used as a front-end treatment device. However, most of the existing cyclone towers use a conventional demisting layer and cannot effectively centrifugally separate water molecules in the waste gas through a swirl plate. Therefore, a large amount of water mist and water molecules are still carried at the air outlet, and the treatment standard cannot be achieved, which in turn affects production efficiency. Moreover, the gas flow rate in the cyclone tower is unstable during operation. When the flow rate is too large, the water molecules cannot be completely centrifugally separated, and when the flow rate is too small, an effective swirl cannot be formed, resulting in poor separation effect. Summary of the Invention

[0004] In view of the problems existing in the above-mentioned existing gas separation devices for air pollution, the present invention is proposed.

[0005] Therefore, the present invention provides a gas separation device for air pollution, and its purpose is to solve the problems that the existing cyclone tower cannot effectively centrifugally separate water molecules in the waste gas through a swirl plate, resulting in a large amount of water mist and water molecules still being carried at the air outlet, making it difficult to meet the treatment standard, and when the cyclone tower is operating, an effective swirl cannot be formed when the flow rate is too large or too small, and the water molecules cannot be completely centrifugally separated.

[0006] To solve the above technical problems, the present invention provides the following technical solutions: a cyclone tower unit, including a cyclone tower body, an exhaust member provided on the cyclone tower body, an activated carbon adsorption layer provided inside the cyclone tower body, a contact layer provided at the bottom of the activated carbon adsorption layer, and a collection member provided at the bottom of the cyclone tower body; An intake unit, including a guiding assembly provided on the cyclone tower body and an adjustment assembly provided on the guiding assembly; A separation unit, including a separation component provided on the guiding assembly, and the separation component is connected to the cyclone tower body; A water tank unit, including a component provided on the cyclone tower body and connected to the contact layer and the collection member.

[0008] As a preferred solution of the gas separation equipment for atmospheric pollution described in the present invention, the adjustment component includes a mounting portion arranged on the outer diameter of the connecting pipe, an electric push rod arranged inside the mounting portion, a driving gear ring arranged at the output end of the adjustment component, a gear shaft arranged on the inner diameter of the driving gear ring, and a connecting seat one arranged at one end of the gear shaft, and the connecting seat one is connected to the connecting pipe.

[0009] As a preferred solution of the gas separation device for atmospheric pollution described in the present invention, seal 1 is provided on the outer diameter of the gear shaft, seal 2 is provided on the outer diameter of the gear shaft, and seal 2 and seal 1 are staggered and rotated inside the mounting portion.

[0010] As a preferred solution of the gas separation device for atmospheric pollution described in the present invention, a seal is provided at the other end of the gear shaft, a second connecting seat is provided at the other end of the seal, and the second connecting seat is connected to the connecting pipe.

[0011] As a preferred solution of the gas separation equipment for atmospheric pollution described in the present invention, the separation component includes an air guide member arranged on the guide portion, a separation tank arranged at the other end of the air guide member, and a disturbance fan arranged inside the separation tank, and the disturbance fan is rotatably connected to the cyclone tower body.

[0012] As a preferred solution of the gas separation device for atmospheric pollution described in the present invention, a spiral shaft is provided at the bottom of the disturbance fan.

[0016] Advantages of the present invention: Through the synergistic effect of the guiding component and the adjusting component, the pipe diameter is adjusted according to the waste gas flow rate, thereby stabilizing the gas flow velocity and ensuring the formation of an effective swirl within the separation component. When a large amount of waste gas impacts the separation component, the driving member, the spiral shaft, and the disturbing fan rotate in coordination to generate a centrifugal force, separating the particulate soot and water mist in the waste gas and flinging them towards the tower wall. At the same time, the spraying system sprays water mist into the tower to further adsorb the particulate matter, causing it to flow into the collecting member with the water flow to achieve solid-liquid separation. The separated gas further removes water molecules through the activated carbon adsorption layer and is finally discharged through the exhaust member, meeting the environmental protection standards. Meanwhile, the device also has an adaptive adjustment ability, which can automatically adjust the diameter of the guiding component according to the size of the waste gas flow rate, ensuring that a stable swirl can be formed for the gas under different working conditions and effectively separating water molecules. This solves the problems of poor separation effect and water mist at the air outlet caused by unstable flow velocity in traditional cyclone towers, enhancing the practicality of waste gas separation.

Detailed implementation manners

[0029] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention in conjunction with the drawings in the specification.

[0030] Example 1, referring to Figure 1 - Figure 4 , which is the first embodiment of the present invention, and provides a gas separation device for air pollution. This device includes: a cyclone tower unit 100, an intake unit 200, a separation unit 300, and a water tank unit 400.

[0031] Among them, the cyclone tower unit 100 includes a cyclone tower body 101, an exhaust part 102 arranged on the cyclone tower body 101, an activated carbon adsorption layer 103 arranged inside the cyclone tower body 101, a contact layer 104 arranged at the bottom of the activated carbon adsorption layer 103, and a collection part 105 arranged at the bottom of the cyclone tower body 101. When separating waste gas, the contact layer 104 increases the contact surface between water and waste gas, so that the ability of water to adsorb soot in the waste gas is further enhanced; The intake unit 200 includes a guiding component 201 disposed on the cyclone tower body 101 and an adjusting component 202 disposed on the guiding component 201. The separation unit 300 includes a separation component 301 disposed on the guiding component 201, and the separation component 301 is connected to the cyclone tower body 101. When separating organic waste gas, by connecting the guiding component 201 to the waste gas conveying pipeline, when the waste gas conveyed through the waste gas pipeline passes through the inside of the guiding component 201, the adjusting component 202 can be adjusted according to the flow rate of the waste gas; The water tank unit 400 includes a spraying component 401 disposed on the cyclone tower body 101, and the spraying component 401 is connected to the contact layer 104 and the collecting member 105. When separating organic waste gas, by connecting the guiding component 201 to the waste gas conveying pipeline, when the waste gas conveyed through the waste gas pipeline passes through the inside of the guiding component 201, the adjusting component 202 can be adjusted according to the flow rate of the waste gas, that is, when the waste gas flow rate inside the guiding component 201 is large, the adjusting component 202 rotates to make the pipeline diameter inside the guiding component 201 larger, so that a large amount of waste gas inside the guiding component 201 can pass through quickly. When the waste gas flow rate inside the guiding component 201 is small, the adjusting component 202 rotates to reduce the diameter inside the guiding component 201, so that the passing waste gas flow rate is restricted and squeezed, so that the waste gas can always ensure the impact of the air flow when passing through the adjusting component 202. The adjusting component 202 can be adjusted at any time according to the waste gas flow rate inside the guiding component 201. And when the waste gas passing through the adjusting component 202 impacts the inside of the separation component 301, due to the control and adjustment of the adjusting component 202, the driving member 3015 inside the separation component 301 starts to rotate under the impact of the air flow, so that a centrifugal force is generated inside the separation component 301. The greater the waste gas flow rate, the stronger the centrifugal force. At the same time, the spraying component 401 starts to spray water inside the separation component 301. During the spraying of the spraying component 401 and the centrifugal rotation of the separation component 301, the ash and dust particles inside the waste gas are all adsorbed by the water, and are thrown to the inner wall of the separation component 301 under the action of the centrifugal force inside the separation component 301, and then slide down along the inner wall of the separation component 301 together with the water under the influence of gravity and are uniformly collected inside the collecting member 105.

[0032] During use, when separating organic waste gas, by connecting the guiding component 201 to the waste gas conveying pipeline, as the waste gas conveyed through the waste gas pipeline passes through the inside of the guiding component 201, the adjusting component 202 can be adjusted according to the waste gas flow rate. That is, when the waste gas flow rate inside the guiding component 201 is large, the adjusting component 202 rotates to adjust, making the pipeline diameter inside the guiding component 201 larger, so that a large amount of waste gas inside the guiding component 201 can pass through quickly. When the waste gas flow rate inside the guiding component 201 is small, the adjusting component 202 rotates to reduce the diameter inside the guiding component 201, restricting and squeezing the passing waste gas flow rate, so that when the waste gas passes through the adjusting component 202, the impact of the air flow can always be ensured. The adjusting component 202 can be adjusted at any time according to the waste gas flow rate inside the guiding component 201. And when the waste gas passing through the adjusting component 202 impacts the inside of the separating component 301, due to the control and adjustment of the adjusting component 202, the driving part 3015 inside the separating component 301 starts to rotate under the impact of the air flow, causing a centrifugal force to be generated inside the separating component 301. The greater the waste gas flow rate, the stronger the centrifugal force. At the same time, the spraying component 401 starts to spray water inside the separating component 301. During the spraying of the spraying component 401 and the centrifugal rotation of the separating component 301, the ash and dust particles inside the waste gas are all adsorbed by the water, and are thrown to the inner wall of the separating component 301 under the action of the centrifugal force inside the separating component 301, and then slide down along the inner wall of the separating component 301 together with the water under the influence of gravity, and are uniformly collected inside the collecting part 105 to achieve the separation of gas, solid and liquid. The separated gas further removes water molecules through the activated carbon adsorption layer 103 and is finally discharged through the exhaust part 102.

[0033] Example 2, refer to Figure 1 - Figure 9, which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: the guide assembly 201 includes a guide portion 2011 arranged on the collecting member 105, a guide member 2012 arranged inside the guide portion 2011, and a connecting pipe 2013 arranged on the guide portion 2011; the adjustment assembly 202 includes a mounting portion 2021 arranged on the outer diameter of the connecting pipe 2013, an electric push rod 2022 arranged inside the mounting portion 2021, a driving gear ring 2024 arranged at the output end of the adjustment assembly 202, a gear shaft 2025 arranged on the inner diameter of the driving gear ring 2024, and a connecting seat 2026 arranged at one end of the gear shaft 2025, The connecting seat 1 2026 is connected to the connecting pipe 2013, a seal 1 2027 is provided on the outer diameter of the gear shaft 2025, a seal 2028 is provided on the outer diameter of the gear shaft 2025, and the seal 2028 and the seal 1 2027 are staggered and rotated inside the mounting portion 2021, the other end of the gear shaft 2025 is provided with a seal 2023, the other end of the seal 2023 is provided with a connecting seat 2029, and the connecting seat 2029 is connected to the connecting pipe 2013. Before separating the organic waste gas, the connecting pipe 2013 is connected to the exhaust port of the waste gas. When the waste gas transported by the waste gas pipeline passes through the inside of the connecting pipe 2013, The seal 1 2027 and the seal 2028 can adjust the exhaust gas volume inside the connecting pipe 2013. When the exhaust gas flow inside the connecting pipe 2013 is too large, the electric push rod 2022 inside the mounting part 2021 works to make the driving gear ring 2024 rotate inside the seal 2023. While the driving gear ring 2024 rotates, the gear shaft 2025 also starts to rotate and shrink with the seal 1 2027 and the seal 2 2028, so that the seal 1 2027 and the seal 2 2028 are all shrunk to the inside of the connecting seat 2 2029 and the connecting seat 1 2026, so that the exhaust gas inside the connecting pipe 2013 can pass through in large quantities. On the contrary, when the exhaust gas flow rate inside the connecting pipe 2013 is small, the electric push rod 2022 inside the mounting part 2021 is extended to make the driving gear ring 2024 move in the opposite direction, so that the gear shaft 2025 rotates and shrinks with the seal 1 2027 and the seal 2 2028, and adjusts the diameter inside the connecting pipe 2013, so that the exhaust gas inside the connecting pipe 2013 has impact, and the adjustment component 202 can be adjusted according to the exhaust gas flow rate inside the connecting pipe 2013, so that the gas can stably form a vortex under different working conditions, effectively separate water molecules, and solve the problem of poor separation effect caused by unstable flow rate in traditional cyclone towers.

[0034] Compared with Embodiment 1, further, the separation component 301 includes a wind guiding member 3011 disposed on the guiding portion 2011, a separation tank 3012 disposed at the other end of the wind guiding member 3011, and a disturbing fan 3013 disposed inside the separation tank 3012. The disturbing fan 3013 is rotatably connected to the cyclone tower body 101. A spiral shaft 3014 is disposed at the bottom of the disturbing fan 3013, and a sewage discharging member 3016 is disposed at the bottom of the spiral shaft 3014. The sewage discharging member 3016 cooperates with the collecting member 105. A driving member 3015 is disposed on the outer diameter of the bottom of the spiral shaft 3014, and the driving member 3015 cooperates with the spiral shaft 3014. The organic waste gas controlled and adjusted by the adjusting component 202 impacts on the driving member 3015 inside the wind guiding member 3011 through the guiding of the guiding portion 2011. As the waste gas flow rate increases, the driving member 3015 begins to rotate. At the same time as the driving member 3015 rotates, the spiral shaft 3014 and the disturbing fan 3013 also rotate together, causing a centrifugal force to be generated inside the wind guiding member 3011. And as the waste gas flow velocity increases, the centrifugal force becomes stronger, enabling effective gas separation of the organic waste gas.

[0035] During use, before separating the organic waste gas, the connecting pipe 2013 is connected to the exhaust outlet of the waste gas. When the waste gas transported through the waste gas pipe passes through the inside of the connecting pipe 2013, the seal member one 2027 and the seal member two 2028 can adjust the amount of waste gas inside the connecting pipe 2013. When the waste gas flow rate inside the connecting pipe 2013 is too large, the electric push rod 2022 inside the installation portion 2021 operates to cause the driving gear ring 2024 to rotate inside the seal member 2023. While the driving gear ring 2024 rotates, the gear shaft 2025 also begins to drive the seal member one 2027 and the seal member two 2028 to rotate and contract, causing the seal member one 2027 and the seal member two 2028 to contract completely into the inside of the connecting seat two 2029 and the connecting seat one 2026, so that a large amount of waste gas inside the connecting pipe 2013 can pass through. On the contrary, when the waste gas flow rate inside the connecting pipe 2013 is small, the electric push rod 2022 inside the installation portion 2021 extends to cause the driving gear ring 2024 to move in the opposite direction, causing the gear shaft 2025 to drive the seal member one 2027 and the seal member two 2028 to rotate and shrink, adjusting the diameter inside the connecting pipe 2013 to make the waste gas inside the connecting pipe 2013 have an impact, enabling the adjusting component 202 to adjust according to the waste gas flow rate inside the connecting pipe 2013, so that the gas can stably form a vortex under different working conditions, effectively separating water molecules, and solving the problem of poor separation effect caused by unstable flow velocity in traditional cyclone towers.

[0036] The organic waste gas controlled and adjusted by the adjustment component 202 impacts the driving component 3015 inside the air guiding component 3011 through the guidance of the guiding part 2011. As the waste gas flow rate increases, the driving component 3015 begins to rotate. While the driving component 3015 rotates, the spiral shaft 3014 and the disturbing fan 3013 also rotate together, causing centrifugal force to be generated inside the air guiding component 3011. And as the waste gas flow velocity increases, the centrifugal force becomes stronger, enabling effective gas separation of the organic waste gas.

[0037] The remaining structure is the same as that of Embodiment 1.

[0038] Embodiment 3, refer to Figure 1 - Figure 10 , is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is: The water tank unit 400 includes a water tank body 4011 provided on one side of the cyclone tower body 101, a water pump 4012 provided on the water tank body 4011, a water pipe 4013 provided at the output end of the water pump 4012, a guiding pipe 4014 provided at the other end of the water pipe 4013, a conveying pipe 4015 provided on the guiding pipe 4014, and a spray head 4016 provided on the conveying pipe 4015. When the waste gas adjusted by the adjustment component 202 is conveyed to the inside of the air guiding component 3011 through the guiding component 201, as the waste gas flow rate increases, the driving component 3015 begins to rotate. While the driving component 3015 rotates, the spiral shaft 3014 and the disturbing fan 3013 also rotate together, causing centrifugal force to be generated inside the air guiding component 3011. And as the waste gas flow velocity increases, the centrifugal force becomes stronger. At the same time, the water pump 4012 also starts to work, pumping the water inside the water tank body 4011 into the water pipe 4013, conveying it through the water pipe 4013 to the guiding pipe 4014 and the conveying pipe 4015, and finally spraying the inside of the air guiding component 3011 through the spray head 4016, so as to cooperate with the centrifugal force inside the air guiding component 3011 to adsorb all the dust and particulate matter in the waste gas. And under the action of the centrifugal force inside the air guiding component 3011, all the dust and particulate matter adsorbed by the water are thrown onto the inner wall of the air guiding component 3011, and then, under the influence of gravity, they flow downward along the inner wall of the air guiding component 3011 together with the water, thus being collected inside the collecting component 105. The separated gas starts to move upward. After being adsorbed by the activated carbon adsorption layer 103 to ensure that there are no water molecules in the gas, the clean gas is discharged through the exhaust component 102, thus completing the separation of the organic waste gas.

[0039] During use, when the waste gas adjusted by the adjusting component 202 is transported to the inside of the air guiding component 3011 through the guiding component 201, as the waste gas flow rate increases, the driving component 3015 begins to rotate. At the same time as the driving component 3015 rotates, the spiral shaft 3014 and the disturbing fan 3013 also rotate together, causing a centrifugal force to be generated inside the air guiding component 3011. And as the waste gas flow velocity increases, the centrifugal force becomes stronger. At the same time, the water pump 4012 also starts to work, transporting the water inside the water tank body 4011 into the water pipe 4013, and through the water pipe 4013 to the guiding pipe 4014 and the conveying pipe 4015, and finally spraying the inside of the air guiding component 3011 through the nozzle 4016, so as to cooperate with the centrifugal force inside the air guiding component 3011 to adsorb all the dust and particulate matter in the waste gas. And under the action of the centrifugal force inside the air guiding component 3011, all the dust and particulate matter adsorbed by the water are thrown onto the inner wall of the air guiding component 3011, and then, under the influence of gravity, they start to flow downward along the inner wall of the air guiding component 3011 together with the water, so as to be collected inside the collecting component 105. The separated gas starts to move upward. After being adsorbed by the activated carbon adsorption layer 103 to ensure that there are no water molecules in the gas, the clean gas is discharged through the exhaust component 102, thus completing the separation of the organic waste gas, ensuring that a stable vortex can be formed under different working conditions, effectively separating water molecules, solving the problems of poor separation effect and water mist at the air outlet caused by unstable flow velocity in the traditional cyclone tower, and enhancing the practicability of waste gas separation.
