Description

Technical Field

[0001] This invention relates to the field of gas treatment technology, and more specifically to an odor gas treatment device for highly polluted environments. Background Technology

[0002] If malodorous gases generated in some highly polluted environments are directly discharged into the atmosphere, they will seriously pollute the surrounding atmospheric environment. Therefore, it is necessary to use malodorous gas treatment equipment to treat the gases before they are discharged.

[0003] Chinese patent document with authorization announcement number 223221257U discloses an odor wet oxidation treatment device, which includes: a gas conveying unit for collecting and conveying odorous gases; and a wet ozone catalytic oxidation unit connected to the gas conveying unit for preliminary treatment of the odorous gases to remove some of the odorous substances in the odorous gases. The above-mentioned prior art has the characteristics of low cost and low pollution, and can be better adapted to the subsequent treatment of odorous gases in industrial enterprises.

[0004] However, during use, the liquid sprayed from the spray component in the gas treatment equipment comes into contact with the malodorous gas and falls to the bottom of the treatment tower. Then, through the circulation component, the liquid at the bottom is transported back to the spray component. However, the malodorous gas also contains some particulate matter, and these particulate matter may cause damage to the spray component and circulation component after entering the circulation system with the liquid.

[0026] Preferably, the deodorization and sterilization mechanism includes an intelligent control module, an aerosol generation unit, a persulfate storage tank, a spiral catalytic mesh I, a spiral catalytic mesh II, and a phase inversion targeted reactor;

[0027] The intelligent control module is connected to the input pipeline; the aerosol generation unit is connected to the input pipeline; the persulfate storage tank is connected to the aerosol generation unit; both the spiral catalytic mesh one and the phase inversion targeted reactor are installed in the primary treatment tower, with the spiral catalytic mesh one located above the phase inversion targeted reactor; the spiral catalytic mesh two is installed in the secondary treatment tower.

[0028] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects:

[0029] Odorous gases enter the input pipeline through the gas delivery unit and then enter the primary treatment tower. At this point, the concentration is detected by the exhaust gas concentration sensor on the intelligent control module. Aerosols are generated by the aerosol generation unit, and highly active free radicals are produced under the action of a catalyst. The persulfate is then transported to the storage bin through the persulfate storage tank. Inorganic free radicals are then generated under the catalysis of the filter metal. Next, the external liquid input source is connected to the input end of the delivery pump, and the liquid is sprayed into the primary treatment tower through the spray nozzle. Subsequently, the odorous gases undergo primary treatment through the phase inversion targeted reactor and the spiral catalytic mesh one. Then, they are transported to the secondary treatment tower through the connecting pipe and the spiral catalytic mesh two for secondary treatment before being discharged.

[0030] When the malodorous gas enters the inner cavity of the primary treatment tower, liquid is sprayed into the inner cavity from the spray nozzles at the bottom of the cylinder. The liquid comes into contact with the particulate matter of the malodorous gas in the primary treatment tower and is filtered by the filter plates on the support plate. The filtered liquid passes through the filter plates and enters the storage chamber for subsequent use. At this time, the drive unit is activated to drive the cylinder to descend. Then, the elasticity of the coil spring causes the end of the support plate near the L-shaped plate to tilt towards the L-shaped plate, while the other end of the support plate is blocked by the round rod and cannot descend. Thus, the support plate presses down the L-shaped plate, connecting the storage chamber and the temporary storage box, and the support... The entire plate is tilted towards an L-shaped plate. At this time, due to the fixation of the pull rope and the storage tank, when the support plate is tilted, the pull rope pulls the blocking plate to move inside the support plate, blocking the bottom of the filter plate. Then, the liquid is sprayed onto the support plate. At this time, the particles above the support plate and above the filter plate are washed into the temporary storage tank by the liquid, thus washing the particles on the filter plate into the temporary storage tank, completing the collection of particles on the filter plate. This achieves the goal of filtering particles by the filter plate while washing the particles with liquid, thus preventing the filter plate from clogging.

[0031] When odorous gas enters the inner cavity of the primary treatment tower, the bending of the bending unit surface turbulently slows down the flow of the odorous gas, promoting its full passage through the phase-inversion targeted reactor and the spiral catalytic mesh, as well as its contact with the liquid. During daily use, the drive unit can be activated to lift the support plate, which in turn lifts the bending unit at the top of the push rod. Then, the support plate separates from the push rod. At this time, the elasticity of the elastic element three causes the bending unit to vibrate, thereby shaking off the water droplets on the surface of the bending unit and preventing liquid from accumulating on the surface of the bending unit, which would reduce the liquid recovery efficiency.

[0032] When the bending unit vibrates, it drives the push rod at the top of the push rod to rise, and then drives the bottom cylinder to rise through the linkage plate, thereby causing the water spray head to move towards the cleaning brush. At this time, the cleaning brush passes through the water spray head and removes the particle crystals generated at the water outlet of the water spray head due to gas or liquid.

[0043] Example 1, as Figures 1-9 As shown, the present invention proposes an odor gas treatment device for highly polluted environments, comprising a primary treatment tower 1, a connecting pipe 2, a secondary treatment tower 3, an input pipe 4, an odorization and sterilization mechanism, a filtration mechanism, a turbulence mechanism, a spraying mechanism, and a gas delivery unit 6; the top of the primary treatment tower 1 is connected to the bottom of the secondary treatment tower 3 through the connecting pipe 2, the input pipe 4 is connected to the primary treatment tower 1, and the gas delivery unit 6 is connected to the input pipe 4;

[0044] The deodorization and sterilization mechanism is installed on the primary treatment tower 1, the input pipeline 4, and the secondary treatment tower 3, and is used to treat gases;

[0045] The filtration unit is installed inside the primary treatment tower 1;

[0046] The flow disturbance mechanism is installed inside the primary treatment tower 1 and is used to slow down the gas flow rate;

[0047] The spraying mechanism is installed at the top inside the primary treatment tower 1 and is used to spray liquid;

[0048] The filtration mechanism includes a support assembly, a filter assembly, a collection assembly, a circulation assembly, and a storage chamber 9. The storage chamber 9 is installed through the bottom of the primary treatment tower 1. The support assembly is installed inside the storage chamber 9. The filter assembly is installed inside the support assembly and is used to filter the liquid. The collection assembly is installed on the storage chamber 9 and is used to collect the liquid containing particulate matter. The two ends of the circulation assembly are connected to the storage chamber 9 and the spraying mechanism, respectively. The filter assembly on the support assembly filters the particles, and then the support assembly carries the filter assembly towards the collection assembly, so that the liquid washes the surface of the filter assembly.

[0049] The support assembly includes a drive unit 10, a cylinder 11, a coil spring 12, and a support plate 14. The drive unit 10 is mounted on the storage chamber 9. The coil spring 12 is mounted inside the cylinder 11. The support plate 14 is connected to the center of the coil spring 12, and the support plate 14 rotates around the center of the coil spring 12. The drive unit 10 drives the cylinder 11 to descend, and the cylinder 11 drives the support plate 14 to tilt towards the L-shaped plate 21 and presses down the L-shaped plate 21, so that the temporary storage box 23 is connected to the storage chamber 9. At this time, the support plate 14 is tilted towards the L-shaped plate 21, so that the particles on the support plate 14 are washed into the temporary storage box 23.

[0050] The filter assembly includes a limiting unit, an elastic element 16, a blocking plate 17, a filter plate 18, and a pull rope 19; the two ends of the elastic element 16 are respectively connected to the support plate 14 and the blocking plate 17; the blocking plate 17 is slidably connected inside the support plate 14, and the filter plate 18 is arrayed on the support plate 14; the two ends of the pull rope 19 are respectively connected to the storage compartment 9 and pass through the support plate 14 to connect to the blocking plate 17.

[0051] The liquid is filtered by the filter plate 18, which accumulates particles. The filtered liquid then falls into the storage chamber 9. When the support plate 14 descends, the support plate 14 moves the blocking plate 17 down because one end of the pull rope 19 is fixed to the storage chamber 9. The pull rope 19 pulls the blocking plate 17 to block the filter plate 18, thereby promoting the liquid to flow into the temporary storage tank 23 after washing away the particles.

[0052] The limiting unit includes a first rectangular plate 13 and a second rectangular plate 15. The first rectangular plate 13 is installed on the outside of the cylinder 11, and the second rectangular plate 15 is installed on the support plate 14. The second rectangular plate 15 presses against the first rectangular plate 13. The first rectangular plate 13 restricts the rotation path of the second rectangular plate 15. Both ends of the support plate 14 are curved surfaces, and the second rectangular plate 15 presses against the first rectangular plate 13. Thus, through the restriction of the second rectangular plate 15 and the first rectangular plate 13, the support plate 14 is prevented from tilting towards the round rod 22, thereby ensuring that the support plate 14 remains flat during the upward movement of the support plate 14.

[0053] The collecting assembly includes an elastic element 20, an L-shaped plate 21, a round rod 22, a temporary storage box 23, and a conveying assembly 27. The two ends of the elastic element 20 are connected to the storage chamber 9 and the L-shaped plate 21, respectively. The L-shaped plate 21 is located on the descending path of the support plate 14. The round rod 22 is installed on the side of the storage chamber 9 away from the L-shaped plate 21, and is located on the descending path of the support plate 14. The temporary storage box 23 is installed on the storage chamber 9. The input end of the conveying assembly 27 is connected to the top of the temporary storage box 23, and its output end is connected to the input pipe 4. As the support plate 14 descends, both ends of the support plate 14 are blocked by the round rod 22 and pressed down by the L-shaped plate 21, causing the temporary storage box 23 and the L-shaped plate 21 to descend. Storage chamber 9 is open; the L-shaped plate 21 is supported by elastic element 20, and the L-shaped plate 21 blocks the storage chamber 9 and temporary storage box 23, preventing the gas inside the primary treatment tower 1 from leaking out of the temporary storage box 23; the liquid entering the temporary storage box 23 is accumulated inside the temporary storage box 23, and then the odorous gas entering the temporary storage box 23 is transported back to the input pipeline 4 by the conveying component 27 for further treatment; a discharge valve is installed at the bottom of the temporary storage box 23. After the liquid accumulates inside the temporary storage box 23, the storage chamber 9 and temporary storage box 23 can be blocked by the L-shaped plate 21, and then the collected liquid can be discharged through the discharge valve at the bottom of the temporary storage box 23.

[0054] The circulation assembly includes a circulation component 25 and a delivery pump 26; the input end of the circulation component 25 is connected to the storage chamber 9, and its output end is connected to the spray assembly; the delivery pump 26 is installed on the circulation component 25; the circulation component 25 delivers the liquid entering the storage chamber 9 to the spray mechanism, and after a portion of the liquid in the inner cavity of the storage chamber 9 is lost, new liquid can be delivered by the delivery pump 26.

[0055] Example 2, as Figure 3 , Figure 4 and Figure 6 As shown, the present invention proposes an odor gas treatment device for highly polluted environments. Compared with Embodiment 1, the turbulence mechanism in this embodiment includes an elastic element 28, a bending unit 29, and a push rod 30.

[0056] The two ends of the elastic element 28 are connected to the primary treatment tower 1 and the bending unit 29 respectively; the bottom end of the bending unit 29 is connected to the push rod 30; the push rod 30 is located on the lifting path of the support plate 14; through the bending shape of the bending unit 29, during the rising process of the odorous gas after entering the primary treatment tower 1 through the input pipe 4, the bending unit 29 blocks the airflow to avoid the situation where the airflow speed is too fast and the reaction is insufficient.

[0057] Example 3, as Figures 2-5As shown, the present invention proposes an odor gas treatment device for highly polluted environments. Compared with Embodiment 2, the spray mechanism of this embodiment includes a linkage plate 31, an elastic element 32, a top cylinder 33, a bottom cylinder 34, a spray head 35, and a cleaning brush 38.

[0058] Linkage plate 31 is installed on top of push rod 30; the two ends of elastic element 32 are respectively connected to linkage plate 31 and top cylinder 33; linkage plate 31 is connected to bottom cylinder 34, and top cylinder 33 is installed on primary treatment tower 1; top cylinder 33 and bottom cylinder 34 are movably connected; spray head 35 is installed at the bottom of bottom cylinder 34, and cleaning brush 38 is installed at the top of the inner cavity of top cylinder 33; linkage plate 31 drives spray head 35 at the bottom of bottom cylinder 34 to rise, so that cleaning brush 38 passes through spray head 35 to clean the outlet of spray head 35; liquid is input into top cylinder 33 and bottom cylinder 34 through transfer pump 26, and then sprayed out into the inner cavity of primary treatment tower 1 through spray head 35; elastic element 16, elastic element 20, elastic element 38 and elastic element 4 32 are composed of telescopic rod and spring, and the spring can be set inside the telescopic rod; there are two spraying mechanisms, which are respectively set above primary treatment tower 1 and secondary treatment tower 3, or a spray water pipe can be set above secondary treatment tower 3.

[0059] Example 4, as Figures 1-3 As shown, the present invention proposes an odor gas treatment device for highly polluted environments. Compared with Embodiment 3, the deodorization and sterilization mechanism of this embodiment includes an intelligent control module 5, an aerosol generation unit 7, a persulfate storage tank 8, a spiral catalytic mesh 1 36, a spiral catalytic mesh 2 37, and a phase inversion targeted reactor 24.

[0060] The intelligent control module 5 is connected to the input pipe 4; the aerosol generating unit 7 is connected to the input pipe 4; the persulfate storage tank 8 is connected to the aerosol generating unit 7; the spiral catalytic mesh 36 and the phase-inversion targeted reactor 24 are both installed in the primary treatment tower 1, with the spiral catalytic mesh 36 located above the phase-inversion targeted reactor 24; the spiral catalytic mesh 37 is installed in the secondary treatment tower 3; the phase-inversion targeted reactor 24 is equipped with a multi-stage catalytic layer, and the surface of the phase-inversion targeted reactor 24 is loaded with a MnO-CeO2 composite catalyst; the intelligent control module 5 is equipped with an odor gas concentration sensor, which monitors the odor gas concentration in real time and adjusts the ultrasonic power and the temperature of the spiral catalytic mesh 36 and the spiral catalytic mesh 37.

[0061] Spiral catalytic mesh 36 and spiral catalytic mesh 37 can be biased with 0.8V to guide free radical targeted attack. First, the persulfate in the persulfate storage tank 8 is converted into aerosol through the aerosol generation unit 7 and then transported to the primary treatment tower 1. Subsequently, the aerosol carrying particulate matter in the malodorous gas triggers a gas-solid-liquid phase inversion reaction with the phase inversion targeted reactor 24 in the primary treatment tower 1, which converts ozone into hydroxyl radicals and sulfate radicals. Meanwhile, the pollutants are decomposed into water and carbon dioxide on the surface of spiral catalytic mesh 36 and spiral catalytic mesh 37 through electron-directed transfer, and then fall into the storage chamber 9.

[0062] In summary, in this invention, the odorous gas is input into the input pipe 4 from the gas delivery unit 6, then passes through the concentration sensor on the intelligent control module 5, and then the persulfate in the persulfate storage tank 8 is converted into aerosol by the aerosol generation unit 7. The aerosol then carries the odorous gas to the primary treatment tower 1. The liquid is then delivered to the top cylinder 33 and the bottom cylinder 34 by the delivery pump 26 and sprayed into the inner cavity of the primary treatment tower 1. At this time, the aerosol carrying the odorous gas rises and is first turbulent by the bending unit 29 to prevent the flow rate from being too fast and thus preventing subsequent full reaction.

[0063] Next, the gas-solid-liquid phase inversion reaction is triggered by the phase inversion targeted reactor 24. Then, the gas at the top of the primary treatment tower 1 enters the secondary treatment tower 3 along the connecting pipe 2, and is decomposed into water and carbon dioxide through electron-directed transfer on the surfaces of the spiral catalytic mesh 36 and spiral catalytic mesh 37.

[0064] In the daily treatment of odorous gases, the liquid mixed with particulate matter is filtered by the filter plate 18 on the support plate 14, and the particulate matter is filtered by the filter plate 18. The filtered liquid falls into the inner cavity of the storage chamber 9, and is then circulated to the top cylinder 33 and the bottom cylinder 34 by the circulation component 25. Then, the liquid is sprayed into the inner cavity of the primary treatment tower 1 by the spray nozzle 35.

[0065] Next, the drive unit 10 is activated to drive the cylinder 11 to descend. The cylinder 11 drives the support plate 14 in the middle of the coil spring 12 to descend, thereby driving the support plate 14 to descend as a whole. One end of the support plate 14 is blocked by the round rod 22, and the other end of the support plate 14 presses the L-shaped plate 21 downward. At this time, the support plate 14 is tilted towards the bottom of the temporary storage box 23. At this time, the pull rope 19 pulled by the storage compartment 9 pulls the blocking plate 17 in the inner cavity of the support plate 14 to move towards the elastic element 16, thereby blocking the filter plate 18 by the blocking plate 17, so that the liquid falling on the support plate 14 no longer passes through the filter plate 18. At this time, the liquid washes the particles on the top of the support plate 14 into the temporary storage box 23 along the inclined surface of the support plate 14.

[0066] The liquid in the temporary storage tank 23 is discharged through the discharge valve at the bottom of the temporary storage tank 23, while the conveying assembly 27 conveys the gas in the temporary storage tank 23 to the input pipe 4.

[0067] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
