Description

Technical Field

[0001] This application relates to the technical field of waste gas treatment, and particularly to a waste gas treatment device. Background Art

[0002] Volatile organic compounds (VOCs) include non-methane hydrocarbons, oxygen-containing organic compounds, halogenated hydrocarbons, nitrogen-containing organic compounds, sulfur-containing organic compounds, etc. Volatile organic compounds mainly come from waste gas generated in processes such as coal chemical industry, petrochemical industry, fuel and coating manufacturing, and solvent manufacturing. Most volatile organic compounds are toxic, irritating, teratogenic, and carcinogenic, seriously affecting people's physical health. Therefore, it is necessary to collect and uniformly treat the waste gas.

[0003] In traditional technologies, high-energy ultraviolet beams are usually used to irradiate waste gas to decompose volatile organic compounds in the waste gas. However, this method has limited decomposition effect on volatile organic compounds in the waste gas, and the treated waste gas still affects people's physical health after being discharged. Summary of the Invention

[0004] Based on this, in view of the problem of poor waste gas treatment effect in traditional technologies, it is necessary to provide a waste gas treatment device.

[0005] Its technical solution is as follows:

[0006] An embodiment provides a waste gas treatment device, including:

[0007] A container having a first chamber, a second chamber, and an exhaust port. The first chamber communicates with the second chamber. A catalytic module is provided in the second chamber, and the exhaust port communicates with the second chamber;

[0008] An ozone intake mechanism provided in the first chamber and having a first intake port for introducing ozone from the first intake port into the first chamber;

[0009] A waste gas intake mechanism provided in the first chamber and having a second intake port for introducing waste gas from the second intake port into the first chamber. The second intake port is disposed opposite to the first intake port.

[0010] The above-mentioned waste gas treatment device, the ozone inlet mechanism and the waste gas inlet mechanism respectively introduce ozone and waste gas into the first chamber. The ozone and the waste gas are mixed in the first chamber and undergo a preliminary oxidation reaction. Subsequently, the mixed ozone and waste gas enter the second chamber. The ozone forms hydroxyl radicals under the catalysis of the catalytic module, and the hydroxyl radicals react with the waste gas again to remove harmful substances in the waste gas. Finally, the waste gas that meets the emission standards is discharged from the exhaust port. During this process, since the first inlet of the ozone inlet mechanism and the second inlet of the waste gas inlet mechanism are oppositely arranged in the first chamber, when the ozone and the waste gas are respectively introduced into the first chamber from the first inlet and the second inlet, the ozone and the waste gas can come into more sufficient contact and mixing. This can not only improve the effect of the preliminary oxidation reaction of the ozone and the waste gas in the first chamber, but also enable the ozone and the waste gas to be fully mixed before entering the second chamber for catalysis by the catalytic module, so that the hydroxyl radicals formed by catalysis can fully react with the waste gas. Compared with the traditional technology, the above-mentioned waste gas treatment device has a better treatment effect on the waste gas and ensures the safety of the waste gas after discharge.

[0035] Please refer to Figure 1 , an embodiment of the present application provides an exhaust gas treatment device 10, including a container 100, an ozone inlet mechanism 200 and an exhaust gas inlet mechanism 300. The container 100 has a first chamber 110, a second chamber 120 and an exhaust port 130. The first chamber 110 is communicated with the second chamber 120. The second chamber 120 is provided with a catalytic module 121. The exhaust port 130 is communicated with the second chamber 120. The ozone inlet mechanism 200 is disposed in the first chamber 110 and is provided with a first inlet 210. The ozone inlet mechanism 200 is used to introduce ozone from the first inlet 210 into the first chamber 110. The exhaust gas inlet mechanism 300 is disposed in the first chamber 110 and is provided with a second inlet 310. The exhaust gas inlet mechanism 300 is used to introduce exhaust gas from the second inlet 310 into the first chamber 110. The second inlet 310 is disposed opposite to the first inlet 210.

[0036] In the above exhaust gas treatment device 10, the ozone inlet mechanism 200 and the exhaust gas inlet mechanism 300 respectively introduce ozone and exhaust gas into the first chamber 110. The ozone and the exhaust gas are mixed in the first chamber 110 and undergo a preliminary oxidation reaction. Subsequently, the mixed ozone and exhaust gas enter the second chamber 120. The ozone forms hydroxyl radicals under the catalysis of the catalytic module 121. The hydroxyl radicals react with the exhaust gas again to remove harmful substances in the exhaust gas. Finally, the exhaust gas reaching the emission standard is discharged from the exhaust port 130. During this process, since the first inlet 210 of the ozone inlet mechanism 200 and the second inlet 310 of the exhaust gas inlet mechanism 300 are disposed opposite to each other in the first chamber 110, when the ozone and the exhaust gas are respectively introduced into the first chamber 110 from the first inlet 210 and the second inlet 310, the ozone and the exhaust gas can come into more sufficient contact and mixing, which can not only improve the effect of the preliminary oxidation reaction of the ozone and the exhaust gas in the first chamber 110, but also enable the ozone and the exhaust gas to be fully mixed and then enter the second chamber 120 to be catalyzed by the catalytic module 121, so that the hydroxyl radicals formed by catalysis can fully react with the exhaust gas. Compared with the traditional technology, the above exhaust gas treatment device 10 has a better treatment effect on exhaust gas and ensures the safety of the exhaust gas after discharge.

[0037] As a supplementary explanation, after the waste gas and ozone are introduced into the first chamber 110, a preliminary oxidation reaction will first occur in the first chamber 110. During this process, a small part of the harmful substances in the waste gas are oxidized by the ozone. Subsequently, the waste gas and ozone enter the second chamber 120 together. The catalytic module 121 catalyzes the ozone to generate hydroxyl radicals, and the hydroxyl radicals then react with the waste gas entering the second chamber 120. Since the waste gas and ozone have been fully mixed before entering the second chamber 120, the hydroxyl radicals formed by the catalytic action of the catalytic module 121 on the ozone can also be fully mixed with the waste gas, thereby performing a multi-effect oxidation reaction on the waste gas, enabling it to be fully oxidized, improving the service life of the catalytic module 121, and reducing the operating cost.

[0038] As a further explanation, in the above embodiment, the relative setting of the first air inlet 210 and the second air inlet 310 means that the first air inlet 210 is arranged facing the second air inlet 310, so that the gas discharged from the first air inlet 210 can generate convection and be fully mixed with the gas discharged from the second air inlet 310.

[0039] Specifically, in one embodiment, the container 100 is a reaction tank, and the first chamber 110 and the second chamber 120 are distributed in the reaction tank in the vertical direction.

[0040] Furthermore, during specific use, a soluble liquid 600, such as water, can also be added to the reaction tank, so that the ozone and the waste gas, as well as the hydroxyl radicals and the waste gas, can be fully mixed in the liquid 600, improving the treatment effect on the waste gas.

[0041] Please refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 , in one embodiment, the ozone intake mechanism 200 includes a first pipeline 220. The first pipeline 220 is used to communicate with the ozone generating device 20. The pipe wall of the first pipeline 220 is provided with a first air inlet 210. The waste gas intake mechanism 300 includes a second pipeline 320. The second pipeline 320 is used to communicate with the waste gas storage device 30. The pipe wall of the second pipeline 320 is provided with a second air inlet 310.

[0042] The ozone generated by the ozone generating device 20 can enter the first pipeline 220 and enter the first chamber 110 through the first air inlet 210 on the first pipeline 220. The waste gas in the waste gas storage device 30 can enter the second pipeline 320 and enter the first chamber 110 through the first air inlet 210 on the second pipeline 320. With such a setting, both the ozone and the waste gas can be smoothly introduced into the first chamber 110, and the introduction process is reliable and the implementation cost is low.

[0043] Furthermore, please refer to Figure 1, the exhaust gas in the exhaust gas storage device 30 is pumped into the second pipeline 320 by a centrifugal fan.

[0044] Please refer to Figure 4 and Figure 5 , in one embodiment, the first pipeline 220 includes a first main pipe 221 and a first branch pipe 222. The first main pipe 221 is used to communicate with the ozone generating device 20. There are at least two first branch pipes 222 which are communicated with the first main pipe 221, and all the first branch pipes 222 are arranged at intervals along the axial direction of the first main pipe 221. There are at least two first air inlets 210 which are arranged at intervals on the first main pipe 221 or / and the first branch pipe 222. The second pipeline 320 includes a second main pipe 321 and a second branch pipe 322. The second main pipe 321 is used to communicate with the exhaust gas storage device 30. There are at least two second branch pipes 322 which are communicated with the second main pipe 321, and all the second branch pipes 322 are arranged at intervals along the axial direction of the second main pipe 321. There are at least two second air inlets 310 which are arranged at intervals on the second main pipe 321 or / and the second branch pipe 322.

[0045] The first main pipe 221 is communicated with the ozone generating device 20 to introduce the ozone generated by the ozone generating device 20 into at least two first branch pipes 222, and then the ozone enters the first chamber 110 from the first air inlet 210. The second main pipe 321 is communicated with the exhaust gas storage device 30 to introduce the exhaust gas into at least two second branch pipes 322, and then the exhaust gas enters the first chamber 110 from the second air inlet 310. The arrangements of the first branch pipe 222 and the second branch pipe 322 can make the ozone and the exhaust gas evenly distributed in the first chamber 110, further ensuring that the ozone and the exhaust gas can be fully mixed.

[0046] As a supplementary explanation, please refer to Figure 4 and Figure 5 , there are at least two first air inlets 210, and the first air inlets 210 are arranged on at least one of the first main pipe 221 and the first branch pipe 222 to ensure the evenness of air intake; correspondingly, there are at least two second air inlets 310, and the second air inlets 310 are arranged on at least one of the second main pipe 321 and the second branch pipe 322 to ensure the evenness of air intake.

[0047] Optionally, the first air inlet 210 can be arranged on the side wall, end, etc. of the first main pipe 221 or the first branch pipe 222, and no specific limitation is made here; similarly for the second air inlet 310, which will not be elaborated here.

[0048] Please refer to Figure 4 and Figure 5, in one embodiment, the ozone intake mechanism 200 further includes a first mounting rod 231, a second mounting rod 232, and a third mounting rod 233.

The first main pipe 221 is provided on the third mounting rod 233. One end of the first branch pipe 222 is provided on the first mounting rod 231, and the other end of the first branch pipe 222 is provided on the second mounting rod 232.

[0049] The first mounting rod 231 is connected to the second mounting rod 232 through the third mounting rod 233. The first main pipe 221 is provided on the third mounting rod 233. One end of the first branch pipe 222 is provided on the first mounting rod 231, and the other end of the first branch pipe 222 is provided on the second mounting rod 232. In this way, effective support can be provided for the first pipeline 220, ensuring the installation strength of the first pipeline 220 and preventing damage to the first pipeline 220.

[0050] Furthermore, in one embodiment, the first main pipe 221 overlaps the side wall of the third mounting rod 233, and the third mounting rod 233 can provide a certain supporting effect for the first main pipe 221 to ensure the installation strength of the first main pipe 221; at least two first branch pipes 222 are provided and spaced apart along the axial direction of the first mounting rod 231. The opposite ends of the first branch pipe 222 overlap the first mounting rod 231 and the second mounting rod 232 respectively to ensure the installation strength of the first branch pipe 222.

[0051] It can be understood that the first main pipe 221 and the third mounting rod 233, as well as the first branch pipe 222 and the first mounting rod 231 and the second mounting rod 232, can also be connected by welding or other means, which will not be elaborated here.

[0052] Please refer to Figure 4 and Figure 5 , as an embodiment that can be implemented simultaneously with the above embodiment, the exhaust gas storage device 30 further includes a fourth mounting rod 331, a fifth mounting rod 332, and a sixth mounting rod 333. The fourth mounting rod 331 and the fifth mounting rod 332 are parallel and spaced apart in the first chamber 110.

The second main pipe 321 is provided on the sixth mounting rod 333. One end of the second branch pipe 322 is provided on the fourth mounting rod 331, and the other end of the second branch pipe 322 is provided on the fifth mounting rod 332.

[0053] The fourth mounting rod 331 is connected to the fifth mounting rod 332 through the sixth mounting rod 333. The second main pipe 321 is provided on the sixth mounting rod 333. One end of the second branch pipe 322 is provided on the fourth mounting rod 331, and the other end of the second branch pipe 322 is provided on the fifth mounting rod 332. In this way, effective support can be provided for the second pipeline 320, ensuring the installation strength of the second pipeline 320 and preventing damage to the second pipeline 320.

[0054] Specifically, the first mounting rod 231, the second mounting rod 232, the third mounting rod 233, the fourth mounting rod 331, the fifth mounting rod 332, and the sixth mounting rod 333 in the above embodiments are all connected to the inner wall of the second chamber 120.

[0055] Please refer to Figures 1 to 2 , in one embodiment, the waste gas treatment device 10 further includes a partition plate 400. The partition plate 400 is provided in the container 100 and divides the inner cavity of the container 100 into a first chamber 110 and a second chamber 120. The partition plate 400 is provided with at least two through holes 410, and the first chamber 110 communicates with the second chamber 120 through the through holes 410.

[0056] The first chamber 110 and the second chamber 120 communicate through the through holes 410 on the partition plate 400. The mixed gas of ozone and waste gas enters the second chamber 120 from the first chamber 110 through the through holes 410 for subsequent catalytic reactions. At least two through holes 410 on the partition plate 400 can make the mixed gas of ozone and waste gas enter the second chamber 120 more dispersedly and evenly, ensuring the subsequent catalytic effect.

[0057] Specifically, please refer to Figure 2 , the through holes 410 are provided in plurality and are uniformly arranged on the partition plate 400, so that the mixed gas of ozone and waste gas can enter the second chamber 120 evenly and dispersedly.

[0058] Furthermore, the catalytic module 121 includes a solid catalyst. The solid catalyst is placed on the partition plate 400, and the partition plate 400 can support the solid catalyst to ensure that the solid catalyst can be stably placed in the container 100.

[0059] Please refer to Figures 2 to 3 , in one embodiment, the waste gas treatment device 10 further includes at least two dispersing members 500, which are provided in one-to-one correspondence with the through holes 410. The dispersing member 500 includes a wire mesh cover 510, a gas guide pipe 520, and a mounting plate 530. The wire mesh cover 510 covers one side of the mounting plate 530 to form a mixing chamber. The gas guide pipe 520 is provided on the other side of the mounting plate 530 and communicates with the mixing chamber. The wire mesh cover 510 is provided with at least two communication ports 511, and all the communication ports 511 are arranged at intervals along the circumference of the wire mesh cover 510. The gas guide pipe 520 is arranged through the through holes 410.

[0060] The circumferential direction of the wire mesh cover 510 is provided with at least two spaced communication ports 511. In this way, when the ozone and waste gas in the first chamber 110 enter the mixing chamber formed by the combination of the wire mesh cover 510 and the mounting plate 530 through the air duct 520, they can enter the second chamber 120 through at least two communication ports 511. The at least two communication ports 511 provided along the circumferential direction of the wire mesh cover 510 can disperse the mixed gas in the mixing chamber to a certain extent, so that the mixed gas formed by ozone and waste gas enters the second chamber 120 more evenly and contacts the catalytic module 121 more evenly to carry out the catalytic reaction, ensuring the subsequent catalytic and oxidation effects.

[0061] Specifically, please refer to Figure 3 , the wire mesh cover 510 is in an umbrella shape and covers the side of the mounting plate 530 away from the air duct 520, and the side wall of the wire mesh cover 510 is provided with a plurality of communication ports 511 at intervals along the circumferential direction of the wire mesh cover 510. In this way, the mixed gas can enter the second chamber 120 through a plurality of communication ports 511 at the same time, ensuring the uniformity of the mixed gas entering the second chamber 120 and further improving the subsequent catalytic effect.

[0062] Please refer to Figure 3 , in one embodiment, a limiting portion 540 is provided at the outer edge of the end of the air duct 520 away from the mounting plate 530, and the limiting portion 540 is used for abutting and cooperating with the outer edge of the through hole 410.

[0063] The limiting portion 540 provided at the end of the air duct 520 away from the mounting plate 530 can abut against the outer edge of the through hole 410 to limit the axial movement of the air duct 520 along the through hole 410 and prevent it from disengaging from the through hole 410.

[0064] Further, the limiting portion 540 includes a protrusion provided at the outer edge of the end of the air duct 520 away from the mounting plate 530, and the protrusion can abut against the outer edge of the through hole 410 to prevent the air duct 520 from falling off from the through hole 410.

[0065] Please refer to Figure 1 , in one embodiment, the second chamber 120 and the first chamber 110 are sequentially arranged in the container 100 along the gravity direction, the container 100 is used to hold the liquid 600, and the catalytic module 121 is immersed in the liquid 600.

[0066] The container 100 is used to hold the liquid 600. The second chamber 120 and the first chamber 110 are arranged in the container 100 in sequence along the direction of gravity, and the catalytic module 121 is immersed in the liquid 600. Thus, when the ozone inlet mechanism 200 and the waste gas inlet mechanism 300 introduce ozone and waste gas into the first chamber 110 respectively, the ozone and the waste gas will dissolve in the liquid 600 and undergo a preliminary oxidation reaction. Subsequently, the mixed gas dissolved in the liquid 600 enters the second chamber 120, and the catalytic module 121 is used to catalyze the ozone. After forming hydroxyl radicals, they come into full contact with the waste gas in the liquid 600 and continue to produce an oxidation reaction, ensuring the reliability of the oxidation reaction process and the reaction time.

[0067] Furthermore, the liquid 600 can be water or other solvents, etc., and no specific limitation is made here.

[0068] Please refer to Figure 1 and Figure 5 In one embodiment, the ozone inlet mechanism 200 further includes an aeration head 240. The aeration head 240 is arranged at the first air inlet 210. The aeration head 240 can make the ozone fully dissolve in the liquid 600, increasing the contact area between the ozone and the liquid 600, and making the oxidation process more sufficient.

[0069] By way of explanation, the aeration head 240, as a special sewage treatment element, can reduce the size of the bubbles, increase the number of bubbles, improve the turbulence degree of the liquid 600, and extend the contact time between the bubbles and the liquid 600, so as to fully dissolve the ozone in the liquid 600.

[0070] Please refer to Figure 1 In one embodiment, the waste gas treatment device 10 further includes a demisting mechanism 700. The demisting mechanism 700 is arranged in the second chamber 120 and is located between the liquid 600 and the exhaust port 130.

[0071] The demisting mechanism 700 arranged between the liquid 600 and the exhaust port 130 can remove the liquid particulate matter in the treated waste gas, preventing the waste gas carrying the liquid particulate matter from being discharged from the exhaust port 130 and polluting the environment.

[0072] Please refer to Figure 1 In one embodiment, the demisting mechanism 700 includes a mounting frame and a wire mesh. The mounting frame is arranged in the second chamber 120 and is located between the liquid 600 and the exhaust port 130, and the wire mesh is arranged on the mounting frame.

[0073] The mounting frame disposed between the liquid 600 and the exhaust port 130 can fix the wire mesh. When the exhaust gas carrying liquid particles passes through the wire mesh, the liquid particles will adhere to the wire mesh when they touch the wire mesh. After repeated adsorption, the liquid particles gather into large droplets. The droplets move along the wire mesh and continue to adsorb liquid particles. When the weight of the droplets is too large, they will fall due to their own gravity to achieve the effect of defogger.

[0074] Furthermore, the screen has multiple layers. When liquid particles touch the upper screen, they will be adhered to the upper screen. After repeated adsorption, the liquid particles will gather into large droplets. Under the action of gravity, the droplets move downward along the intersections between the different layers of screens and continue to adsorb liquid particles. The grown liquid particles flow to the bottom screen and fall down by their own gravity. The above method is used for demisting, which has the characteristics of small pressure drop, large specific surface area and high demisting efficiency. For liquid particles larger than 3μm, the demisting efficiency can reach more than 98%.

[0075] See also Figure 1 In one embodiment, an ozone concentration monitoring mechanism 800 is also provided at the exhaust port 130. The ozone concentration monitoring mechanism 800 can monitor the ozone concentration in real time, reasonably control the amount of ozone entering, reduce the operating costs of the device, and reduce the secondary pollution of ozone to the air.

[0076] See also Figure 1 In one embodiment, a drain valve 900 is further provided at the bottom of the container 100, through which the liquid 600 can be regularly replaced to ensure the normal operation of the device.

[0077] See also Figure 1 In one embodiment, the exhaust gas treatment device 10 further includes an exhaust pipe, which is connected to the exhaust port 130 and is used to discharge the treated exhaust gas.

[0078] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
