Description

Technical Field

[0001] The present application relates to the technical field of waste gas treatment, and in particular to a waste gas treatment device. Background Art

[0002] The panel industry generates a large amount of waste gas during production. This waste gas contains a variety of components, including some that are easily soluble in water and others that are insoluble. Directly discharging this waste gas into the atmosphere can cause severe environmental pollution. Existing waste gas treatment equipment primarily uses physical and chemical methods to treat waste gas. Physical methods primarily involve adsorption and condensation. However, these devices treat waste gas of varying components using the same method, for example, simultaneously utilizing both atomization and condensation. This results in poor waste gas treatment effectiveness and can easily lead to wasteful resources. Utility Model Content

[0003] The purpose of this application includes, for example, providing an exhaust gas treatment device that can adjust the opening and closing of atomization and condensation according to the composition of the exhaust gas to improve the treatment effect and reduce resource waste.

[0004] The embodiments of the present application can be implemented as follows:

[0005] An embodiment of the present application provides an exhaust gas treatment device, which includes an exhaust gas inlet pipe, an exhaust gas composition detector, an atomization treatment device, a condensation treatment device and a controller. The exhaust gas composition detector can detect the composition of the exhaust gas when the exhaust gas passes through the exhaust gas inlet pipe, the atomization treatment device can atomize the exhaust gas when the exhaust gas passes through itself, and the condensation treatment device can condense the exhaust gas when the exhaust gas passes through itself. The exhaust gas composition detector, the atomization treatment device and the condensation treatment device perform exhaust gas composition detection, atomization treatment and condensation treatment on the exhaust gas in turn, and the treated gas is discharged through the condensation treatment device. The controller is electrically connected to the exhaust gas composition detector, the atomization treatment device and the condensation treatment device at the same time, and can obtain the composition of the exhaust gas detected by the exhaust gas composition detector. According to the obtained exhaust gas composition, the controller controls the opening and closing and adjustment of the atomization treatment device, and controls the opening and closing and adjustment of the condensation treatment device.

[0006] In the process of using the exhaust gas treatment equipment to treat the exhaust gas, the exhaust gas composition detector first detects the composition of the exhaust gas and transmits it to the controller. The controller controls the opening and closing and adjustment of the atomization treatment device according to the acquired exhaust gas composition, as well as the opening and closing and adjustment of the condensation treatment device, so that the exhaust gas treatment method is more adapted to the exhaust gas composition, thereby making the exhaust gas treatment effect better and less likely to cause waste of resources.

[0017] It should be noted that, in the absence of conflict, the features in the embodiments of this application can be combined with each other.

[0018] The inventors of this application have discovered that existing waste gas treatment equipment utilizes both atomization and condensation to treat waste gas, but cannot adjust the atomization and condensation modes based on the composition of the waste gas, resulting in poor waste gas treatment and a waste of resources. The embodiments of this application provide a waste gas treatment device that at least addresses this technical problem.

[0019] Please refer to Figure 1-Figure 3 The exhaust gas treatment equipment provided in the embodiment of the present application includes an exhaust gas component detector 100, an atomization treatment device 200, a condensation treatment device 300, a controller 400 and an exhaust gas inlet pipe 500. The exhaust gas component detector 100 is arranged on the exhaust gas inlet pipe 500 for detecting the components of the exhaust gas. The exhaust gas inlet pipe 500, the atomization treatment device 200 and the condensation treatment device 300 are connected in sequence. The atomization treatment device 200 is used to atomize the exhaust gas, and the condensation treatment device 300 is used to condense the exhaust gas. The controller 400 is electrically connected to the exhaust gas component detector 100, the atomization treatment device 200 and the condensation treatment device 300 at the same time, and is used to control the opening and closing and adjustment of the atomization treatment device 200 and the condensation treatment device 300 according to the detection results of the exhaust gas component detector 100.

[0020] In some examples, the exhaust gas composition detector 100 can send the detected exhaust gas composition parameters to the controller 400. The controller 400 stores multiple gas identification codes, and the multiple gas identification codes correspond to multiple exhaust gas components. After the controller 400 obtains the composition of the exhaust gas through the exhaust gas composition detector 100, it controls the opening and closing of the atomization treatment device 200 and the opening and closing of the condensation treatment device 300 according to the corresponding gas identification code.

[0021] Exemplarily, when the exhaust gas detected by the exhaust gas component detector 100 only contains waste gas components that are easily soluble in water, such as NMP, the controller 400 controls the atomization treatment device 200 to open, and controls the condensation treatment device 300 to close. At this time, only the exhaust gas is subjected to atomization treatment; when the exhaust gas detected by the exhaust gas component detector 100 only contains waste gas components that are not easily soluble in water, such as BDG and MEA, the controller 400 controls the atomization treatment device 200 to close, and controls the condensation treatment device 300 to open. At this time, only the exhaust gas is subjected to condensation treatment; and when the exhaust gas detected by the exhaust gas component detector 100 contains both waste gas components that are easily soluble in water, such as NMP, and waste gas components that are not easily soluble in water, such as BDG and MEA, the controller 400 controls the atomization treatment device 200 to open, and controls the condensation treatment device 300 to open. At this time, the exhaust gas is subjected to both atomization treatment and condensation treatment.

[0022] In the process of treating the waste gas using the waste gas treatment equipment, the waste gas component detector 100 detects the components of the waste gas. When the waste gas only contains waste gas components that are easily soluble in water, the controller 400 only controls the atomization treatment device 200 to turn on; when the waste gas only contains waste gas components that are not easily soluble in water, the controller 400 controls the atomization treatment device 200 to be closed, and only controls the condensation treatment device 300 to be turned on; when the waste gas contains both waste gas components that are easily soluble in water and waste gas components that are not easily soluble in water, the controller 400 controls the atomization treatment device 200 to be turned on, and the controller 400 controls the condensation treatment device 300 to be turned on, so that the waste gas treatment method is more adapted to the composition of the waste gas, thereby making the waste gas treatment effect better, and thus less likely to cause waste of resources.

[0023] In this embodiment, the atomization treatment device 200 includes a cavity 210, an air intake pipe 220, a first water intake pipe 230 and an atomizing nozzle 231. The cavity 210 is connected to the exhaust gas inlet pipe 500. The air intake pipe 220 and the first water intake pipe 230 are at least partially arranged in the cavity 210 and are both connected to the atomizing nozzle 231. The air intake pipe 220 and the first water intake pipe 230 are both provided with a first proportional solenoid valve 240 electrically connected to the controller 400.

[0024] The air intake pipe 220 is used to introduce compressed air, and the first water intake pipe 230 is used to introduce public water. The air intake pipe 220 and the first water intake pipe 230 are partially arranged in the cavity 210. The first proportional solenoid valve 240 on the air intake pipe 220 is arranged in the part of the air intake pipe 220 located outside the cavity 210. The first proportional solenoid valve 240 on the first water intake pipe 230 is arranged in the part of the first water intake pipe 230 located outside the cavity 210. The atomizing nozzle 231 is arranged in the cavity 210. The number of atomizing nozzles 231 is reasonably arranged according to the model and the cross-section of the cavity 210, so that the spraying area of the atomizing nozzle 231 fully covers the cross-section of the cavity 210.

[0025] Among them, the first proportional solenoid valve 240 is electrically connected to the controller 400 using the RS-485 serial bus standard. Data can be transmitted to the controller 400 over a long distance in an anti-interference manner through the RS-485 serial bus standard. The PID algorithm inside the controller 400 keeps the compressed air and water at the optimal gas-liquid setting ratio, thereby constructing a stable and precise atomization treatment device 200. Among them, the first proportional solenoid valve 240 can be a servo proportional valve. In this way, the first proportional solenoid valve 240 can infinitely and accurately adjust the pressure of the compressed air and the water flow rate to ensure that the atomizing nozzle 231, which uses the spraying effect of compressed air to atomize the water body, has a stable and precise supply of compressed air and water, so that the atomized water is evenly and finely sprayed, and the exhaust gas passing through is evenly humidified and dissolved in water to form droplets, thereby completing gas-liquid separation and ensuring the treatment effect of the atomization treatment device 200.

[0026] When the atomizing treatment device 200 is needed, the controller 400 controls the first proportional solenoid valve 240 on the air intake pipe 220 and the first water intake pipe 230 to open, and the compressed air in the air intake pipe 220 and the water in the first water intake pipe 230 are sprayed out through multiple atomizing nozzles 231, thereby dissolving the water-soluble exhaust gas components in the exhaust gas into water to form droplets.

[0027] In this embodiment, the atomization treatment device 200 also includes a compressed air pipeline 250 and a water supply pipeline 260. The number of air intake pipelines 220 is multiple, and the compressed air pipeline 250 is simultaneously connected to multiple air intake pipelines 220. The number of first water intake pipelines 230 is multiple, and the water supply pipeline 260 is simultaneously connected to multiple first water intake pipelines 230. Each first water intake pipeline 230 and each air intake pipeline 220 are respectively connected to multiple atomization nozzles.

[0028] The compressed air pipeline 250 and the water supply pipeline 260 are both arranged outside the cavity 210. The compressed air pipeline 250 is used to introduce compressed air, and the compressed air pipeline 250 simultaneously provides compressed air to multiple air inlet pipelines 220; the water supply pipeline 260 is used to introduce public water, and the water supply pipeline 260 simultaneously provides public water to multiple first water inlet pipelines 230; each first water inlet pipeline 230 is connected to multiple atomizing nozzles 231 at the same time, and each air inlet pipeline 220 is connected to multiple atomizing nozzles 231 at the same time.

[0029] Exemplarily, a single air intake pipe 220 is located between two first water intake pipes 230, and the single air intake pipe 220 is connected to two rows of atomizing nozzles 231. The first water intake pipe 230 adjacent to the air intake pipe 220 is connected to a row of atomizing nozzles 231. The air intake pipe 220 and the two first water intake pipes 230 adjacent to the air intake pipe 220 form a spray group. By arranging multiple spray groups at intervals in the cavity 210, the treatment effect of the exhaust gas entering the cavity 210 can be improved.

[0030] In this embodiment, a first electromagnetic switch valve 261 and a first electromagnetic flowmeter 262 are provided on the compressed air pipeline 250 and the water supply pipeline 260 , and the controller 400 is electrically connected to the first electromagnetic switch valve 261 and the first electromagnetic flowmeter 262 .

[0031] By installing a first electromagnetic on-off valve 261 on both the compressed air pipeline 250 and the water supply pipeline 260, and electrically connecting the first electromagnetic on-off valve 261 to the controller 400, the controller 400 can control the opening and closing of the first electromagnetic on-off valve 261, thereby controlling the on-off of the compressed air pipeline 250 and the water supply pipeline 260. By installing a first electromagnetic flowmeter 262 on both the compressed air pipeline 250 and the water supply pipeline 260, and electrically connecting the first electromagnetic flowmeter 262 to the controller 400, the controller 400 can monitor the gas flow in the compressed air pipeline 250 and the water flow in the water supply pipeline 260 in real time through the first electromagnetic flowmeter 262.

[0032] In some embodiments, a first filter 251 for filtering impurities is provided on the compressed air pipeline 250. Specifically, the compressed air contains impurities, such as liquid impurities such as oil mist and solid particles. By providing the first filter 251 on the compressed air pipeline 250, the impurities flowing in the compressed air pipeline 250 are filtered to improve the purity of the compressed air.

[0033] In some embodiments, the compressed air pipeline 250 and the water supply pipeline 260 are each provided with a pressure gauge 263 for detecting the pressure within the compressed air pipeline 250 and the water supply pipeline 260, respectively. The compressed air pipeline 250 and the water supply pipeline 260 are each also provided with a first one-way valve 264 for preventing backflow of compressed air within the compressed air pipeline 250 and backflow of water within the water supply pipeline 260, respectively. The water supply pipeline 260 is also provided with a first safety valve 265.

[0034] In this embodiment, the condensation treatment device 300 includes a surface cooler 310, a second water inlet pipe 320 and a return water pipe 330. The air inlet of the surface cooler 310 is connected to the atomization treatment device 200, and the second water inlet pipe 320 and the return water pipe 330 are respectively connected to the water inlet and return water port of the surface cooler 310. A second electromagnetic switch valve 322 electrically connected to the controller 400 is provided on the second water inlet pipe 320.

[0035] It should be noted that the cooler 310 has a water inlet and a water return port. The second water inlet pipe 320 is connected to the water inlet of the cooler 310, and the return water pipe 330 is connected to the return water port of the cooler 310. The second water inlet pipe 320 is used to pass low-temperature water into the internal pipes of the cooler 310 through the water inlet of the cooler 310, and the return water pipe 330 is used to return water to the external refrigeration equipment through the return water port of the cooler 310. The cooler 310 has an air inlet and an exhaust port. The air inlet of the cooler 310 is connected to the cavity 210 in the atomization treatment device 200, and the exhaust port of the cooler 310 is used to discharge the treated gas.

[0036] When the condensation treatment device 300 needs to be used, the second electromagnetic switch valve 322 is controlled to open by the controller 400, and the low-temperature water in the second water inlet pipe 320 flows to the internal pipe of the surface cooler 310, so that a low-temperature zone is formed inside the surface cooler 310. When the high-temperature exhaust gas passes through the internal space of the surface cooler 310, the exhaust gas components that are not easily soluble in water in the exhaust gas are condensed into liquid, and then discharged through the exhaust port of the surface cooler 310.

[0037] In this embodiment, a first pressure transmitter 323 , a first temperature transmitter 324 and a second electromagnetic flowmeter 325 are provided on the second water inlet pipe 320 , and the controller 400 is electrically connected to the first pressure transmitter 323 , the first temperature transmitter 324 and the second electromagnetic flowmeter 325 at the same time.

[0038] By setting a first pressure transmitter 323, a first temperature transmitter 324 and a second electromagnetic flowmeter 325 on the second water inlet pipe 320, the controller 400 can obtain the water pressure, water temperature and water flow in the second water inlet pipe 320 in real time through the first pressure transmitter 323, the first temperature transmitter 324 and the second electromagnetic flowmeter 325 on the second water inlet pipe 320.

[0039] In this embodiment, a second proportional solenoid valve 331, a third solenoid switch valve 332, a second pressure transmitter 333 and a second temperature transmitter 334 are provided on the return water pipe 330. The third solenoid switch valve 332 and the second proportional solenoid valve 331 are connected in parallel, and the controller 400 is electrically connected to the third solenoid switch valve 332, the second proportional solenoid valve 331, the second pressure transmitter 333 and the second temperature transmitter 334 at the same time.

[0040] By providing the second pressure transmitter 333 and the second temperature transmitter 334 on the return water pipeline 330 , the controller 400 can obtain the water pressure and water temperature in the return water pipeline 330 in real time through the second pressure transmitter 333 and the second temperature transmitter 334 on the return water pipeline 330 .

[0041] A manual valve 335 and a second safety valve 336 are also provided on the return water pipeline 330. There are two manual valves 335, one of which is close to the surface cooler 310, and the other is close to the external refrigeration equipment. The second proportional solenoid valve 331 is located between the two manual valves 335. The third solenoid switch valve 332 is connected in parallel with the second proportional solenoid valve 331 and the two manual valves 335. Under normal working conditions, the manual valve 335 is normally open, the second proportional solenoid valve 331 is open, and the third solenoid switch valve 332 is closed.

[0042] When the second proportional solenoid valve 331 fails and needs to be replaced and repaired, the two manual valves 335 are fully closed, and the third solenoid switch valve 332 is controlled to open by the controller 400 so that the return water pipeline 330 can return water normally.

[0043] In some embodiments, a second filter 321 for filtering impurities is provided on the second water inlet pipe 320. By providing the second filter 321 on the second water inlet pipe 320, impurities in the second water inlet pipe 320 are filtered to improve the purity of the low-temperature water, prevent clogging, ensure the normal operation of the equipment, and reduce maintenance.

[0044] In some embodiments, a second one-way valve 326 is provided on the second water inlet pipe 320 to prevent the low-temperature water in the second water inlet pipe 320 from flowing back.

[0045] In this embodiment, the exhaust gas treatment equipment further includes an exhaust gas volume detector 600 provided on the exhaust gas inlet pipe 500 for detecting the exhaust gas volume. The exhaust gas volume detector 600 is electrically connected to the controller 400 .

[0046] The controller 400 detects the exhaust gas volume detected by the exhaust gas volume detector 600 and adjusts the opening of the second proportional solenoid valve 331 on the return water pipe 330 based on the detected exhaust gas volume to ensure the condensation efficiency of the exhaust gas treatment equipment. Specifically, when the exhaust gas volume increases or decreases, the controller 400 controls the opening of the second proportional solenoid valve 331 based on the data feedback, thereby adjusting the cold water flow rate in a timely manner to ensure condensation efficiency.

[0047] The working principle of the exhaust gas treatment equipment provided in the embodiment of the present application is as follows: in the process of treating the exhaust gas, the exhaust gas air volume detector 600 and the exhaust gas component detector 100 respectively detect the air volume and components of the exhaust gas. When the exhaust gas component detector 100 detects that the exhaust gas only contains exhaust gas components that are easily soluble in water, the controller 400 only controls the atomization treatment device 200 to open, that is, the controller 400 controls the electromagnetic switch valves on the compressed air pipeline 250 and the water supply pipeline 260 to open, and controls the first proportional solenoid valve 240 on the air intake pipeline 220 and the first water intake pipeline 230 to open and adjusts the opening of the first proportional solenoid valve 240, thereby controlling the degree of atomization; when the exhaust gas component detector 100 detects that the exhaust gas only contains exhaust components that are not easily soluble in water When the exhaust gas contains both water-soluble and insoluble exhaust gas components, the controller 400 controls the atomization treatment device 200 to open, and the controller 400 controls the condensation treatment device 300 to open, that is, the controller 400 controls the second electromagnetic switch valve 322 on the second water inlet pipe 320 to open. When the exhaust gas volume detector 600 detects that the exhaust gas volume increases or decreases, the controller 400 controls the opening size of the second proportional electromagnetic valve 331 on the return water pipe 330 to ensure the condensation treatment efficiency. When the exhaust gas contains both water-soluble and water-insoluble exhaust gas components, the controller 400 controls the atomization treatment device 200 to open, and the controller 400 controls the condensation treatment device 300 to open, so that the exhaust gas treatment method is more adapted to the exhaust gas composition, thereby making the exhaust gas treatment effect better and thus less likely to cause waste of resources.

[0048] The technical effects of the exhaust gas treatment equipment provided by the embodiment of the present application include at least: the controller 400 can control the opening and closing of the atomizing treatment device 200 and the condensing treatment device 300 according to the exhaust gas components detected by the exhaust gas component detector 100; when the exhaust gas contains only exhaust gas components that are easily soluble in water, the controller 400 only controls the atomizing treatment device 200 to be turned on; when the exhaust gas contains only exhaust gas components that are not easily soluble in water, the controller 400 only controls the condensing treatment device 300 to be turned on; when the exhaust gas contains both exhaust gas components that are easily soluble in water and exhaust gas components that are not easily soluble in water, the controller 400 controls the atomizing treatment device 200 and the condensing treatment device 300 to be turned on at the same time, thereby effectively treating the exhaust gas. The treatment method is more adapted to the exhaust gas composition, thereby achieving a better exhaust gas treatment effect and less likely to cause waste of resources; the controller 400 can adjust the opening size of the second proportional solenoid valve 331 on the return water pipe 330 according to the exhaust gas volume detected by the exhaust gas volume detector 600 to ensure the condensation treatment efficiency of the exhaust gas treatment equipment; by providing a first filter 251 on the compressed air pipe 250, impurities flowing in the compressed air pipe 250 are filtered to improve the purity of the compressed air; by providing a second filter 321 on the second water inlet pipe 320, impurities in the second water inlet pipe 320 are filtered to improve the purity of the low-temperature water.

[0049] In summary, the embodiment of the present application provides a waste gas treatment device. During the process of treating the waste gas, the waste gas enters the cavity 210 through the waste gas inlet pipe 500, and the waste gas component detector 100 detects the components of the waste gas. When the waste gas only contains waste gas components that are easily soluble in water, the controller 400 only controls the atomization treatment device 200 to turn on; when the waste gas only contains waste gas components that are not easily soluble in water, the controller 400 only controls the condensation treatment device 300 to turn on; when the waste gas contains both waste gas components that are easily soluble in water and waste gas components that are not easily soluble in water, the controller 400 controls the atomization treatment device 200 and the condensation treatment device 300 to turn on at the same time; the waste gas air volume detector 600 detects the air volume of the waste gas, and the controller 400 can adjust the opening size of the second proportional solenoid valve 331 on the return water pipe 330 according to the air volume of the waste gas detected by the exhaust gas air volume detector 600.
