Description

Technical Field

[0001] The utility model relates to the technical field of purification equipment, in particular to a fume purification device utilizing ozone water for deodorization. Background Art

[0002] At present, some industries in industrial production will produce a large amount of oil smoke during the production process. These oil smoke gases contain many odor molecules such as ammonia, trimethylamine, hydrogen sulfide, methyl mercaptan, methyl sulfide, dimethyl disulfide, carbon disulfide and styrene. These oil smoke gases will cause environmental pollution if they are directly discharged into the air, endangering the health of surrounding residents.

[0003] Usually, some oil fume purification equipment is installed in the production workshop, and the more common one is the tower purification device, such as the existing technologies such as a new organic oil fume gas treatment device disclosed in Chinese Patent Publication No. CN213643697U and an odorous oil fume gas ozone water oxidation deodorization and disinfection device disclosed in Chinese Patent Publication No. CN212942271U.

[0004] The oil fume purification equipment in the existing technology usually uses a spray head to directly spray ozone water. The ozone water contacts the oil fume gas and uses the ozone water to decompose and remove the odor molecules in the oil fume gas. The contact effect between the ozone water and the oil fume gas is not very good if it is only sprayed, and some oil fume gas is easily discharged directly from the device.

[0005] Therefore, the existing technology still needs to be improved and developed. Utility Model Content

[0006] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide an oil fume purification device that uses ozone water for deodorization, so as to solve the problem that the prior art only sprays ozone water by spraying, resulting in unsatisfactory contact effect between ozone water and oil fume gas.

[0007] An oil fume purification device using ozone water for deodorization, characterized by comprising:

[0008] A chassis, wherein the chassis is provided with an inlet for introducing oil fume gas and an outlet for discharging oil fume gas, a gas passage connecting the inlet and the outlet is provided in the chassis, and the airflow direction in the gas passage is from bottom to top;

[0009] an aeration module, comprising an aeration net disposed in the gas channel and separating the gas channel, the aeration net being provided with a plurality of air holes;

[0010] an ozone water spray module, comprising a nozzle disposed above the aeration net and spraying ozone water toward the aeration net;

[0011] After the aeration module is turned on, an ozone water vapor bubble film is formed on the upper end of the aeration net.

[0012] Specifically, the ozone water spray module further includes an ozone generator for generating ozone, an ozone water mixing device connected to the air outlet of the ozone generator and used to produce ozone water, and a liquid pump for pumping the ozone water produced by the ozone water mixing device to the nozzle.

[0013] Specifically, a water collecting tank is provided at the bottom of the gas channel, and the ozone water in the water collecting tank flows back to the ozone water mixing device through a pipeline or is directly discharged to the outside.

[0014] Specifically, the oil fume purification device includes a water vapor intercepting module disposed above the nozzle and used for intercepting water vapor.

[0015] Specifically, the water vapor interception module includes a driving device fixed to the chassis, and a baffle connected to the output end of the driving device. The baffle is provided with a plurality of through holes for the oil smoke gas to pass through.

[0016] Specifically, the aeration module further includes an aeration box detachably fixed to the chassis, the aeration box is connected vertically, and the aeration net is detachably fixed to the lower end of the aeration box.

[0017] Specifically, the chassis is provided with an inspection window, and the inspection window is located on one side of the aeration box.

[0018] Beneficial effects of the utility model:

[0019] The oil fume purification equipment of the present invention can be applied to scenes such as industrial workshops, restaurant kitchens, and garbage disposal stations where oil fume purification and deodorization are required. When deodorization and purification are required in these scenes, when the oil fume gas in the gas channel flows from bottom to top, after the aeration module is started, the nozzle sprays ozone water toward the aeration net. Since the oil fume gas passes through the pores of the aeration net from bottom to top, a layer of ozone water bubble film will be formed on the upper end of the aeration net. The oil fume gas passes through the ozone water bubble film and has more contact with the ozone water. After the ozone water comes into contact with the odor molecules in the oil fume gas, it can decompose and remove them. Finally, the oil fume gas discharged through the outlet of the chassis is non-toxic and odorless and meets the emission standards. BRIEF DESCRIPTION OF THE DRAWINGS

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0028] like Figures 1 to 5 This embodiment discloses a fume purification device for deodorizing with ozone water, comprising:

[0029] The chassis 10 is provided with an inlet 11 for introducing oil fume gas and an outlet 12 for discharging oil fume gas. A gas passage 13 is provided in the chassis 10 to connect the inlet 11 and the outlet 12. The airflow direction in the gas passage 13 is from bottom to top.

[0030] The aeration module 20 includes an aeration net 21 disposed in the gas channel 13 and separating the gas channel 13. The aeration net 21 has a plurality of air holes 211.

[0031] The ozone water spray module includes a nozzle 31 disposed above the aeration net 21 and spraying ozone water toward the aeration net 21;

[0032] After the aeration module 20 and the exhaust module are turned on, an ozone water vapor bubble film is formed on the upper end of the aeration net 21.

[0033] The oil fume purification equipment of this embodiment can be applied to scenes such as industrial workshops, restaurant kitchens, and garbage disposal stations where oil fume purification and deodorization are required. Specifically, pipes can be used to connect the indoor space of these scenes with the inlet 11 of the chassis 10. The exhaust module can also be used in conjunction with the exhaust module. The exhaust module can be connected to one end of the inlet 11 or one end of the outlet 12 to drive the oil fume gas in the gas channel 13 to flow from bottom to top. When deodorization and purification are required in these scenes, the exhaust module and the aeration module 20 can be turned on to cooperate with the exhaust function of the exhaust module. The oil fume gas in the channel 13 flows from bottom to top. After the aeration module 20 is started, the nozzle 31 sprays ozone water toward the aeration net 21. Since the oil fume gas passes through the air holes 211 of the aeration net 21 from bottom to top, a layer of ozone water bubble film will be formed on the upper end of the aeration net 21. The oil fume gas passes through the ozone water bubble film and has more contact with the ozone water. After the ozone water comes into contact with the odor molecules in the oil fume gas, it can decompose and remove them. Finally, the oil fume gas discharged through the outlet 12 of the chassis 10 is non-toxic and odorless, and meets the emission standards.

[0034] In addition, the nozzle 31 also has an ozone water compensation function. Since the ozone water will flow down through the pores 211 of the aeration net 21, in order to ensure that the ozone water bubble film can be continuously formed at the upper end of the aeration net 21, it is also necessary to combine the flow rate of the ozone water flowing down from the pores 211 to appropriately control the flow rate of the ozone water sprayed out of the nozzle 31.

[0035] It should be noted that in order to ensure that a layer of ozone water vapor bubble film can be formed on the upper end of the aeration net 21, the aperture of the pore 211 cannot be set too large. If the aperture of the pore 211 is set too large, the ozone water will flow down through the pore 211 of the aeration net 21, making it difficult to form the ozone water vapor bubble film; and the aperture of the pore 211 cannot be set too small. Because if the aperture of the pore 211 is too small, the efficiency of the oil smoke gas passing through the pore 211 is low, affecting the deodorization efficiency.

[0036] For further information, please refer to Figure 1 The exhaust module of this embodiment includes a fan 41, which is arranged at one end of the outlet 12 of the chassis 10. After the fan 41 is started, under the action of negative pressure, the oil smoke gas can quickly pass into the gas channel 13 from the inlet 11 of the chassis 10. Moreover, due to the exhaust effect of the fan 41, the ozone water bubble film on the aeration net 21 has the power to tend toward the outlet 12 of the chassis 10 under the action of wind, which slows down the speed of the ozone water falling directly from the air hole 211, which is more conducive to the formation of the ozone water bubble film on the upper end of the aeration net 21.

[0037] Furthermore, the ozone water spray module of this embodiment also includes an ozone generator 32 for generating ozone, an ozone water mixing device 33 connected to the air outlet of the ozone generator 32 and used to produce ozone water, and a liquid pump 34 for pumping the ozone water produced by the ozone water mixing device 33 to the nozzle 31. The ozone generated by the ozone generator 32 is passed into the ozone water mixing device 33 through a pipe. Water can be automatically added to the ozone water mixing device 33 and it has a stirring function, so that the ozone and water are evenly mixed to produce ozone water. The ozone water in the ozone water mixing device 33 is then pumped to the nozzle 31 by the liquid pump 34 and finally sprayed out from the nozzle 31.

[0038] In addition, since part of the ozone water will flow down through the air holes 211, in order to recycle this part of the ozone water, this embodiment provides a water collecting tank 14 at the bottom of the gas channel 13. The ozone water in the water collecting tank 14 flows back to the ozone water mixing device 33 through a pipeline, thereby realizing the resource reuse of ozone water and reducing the manufacturing cost of ozone water.

[0039] Please refer to Figure 1 The oil fume purification device of this embodiment includes a water vapor interception module 50 arranged above the nozzle 31 and used to intercept water vapor. By setting the water vapor interception module 50, ozone water can be effectively intercepted to prevent a small amount of ozone water from being directly discharged from the outlet 12 of the chassis 10 under the action of wind pressure.

[0040] Furthermore, the water vapor interception module 50 of this embodiment includes a driving device 51 fixed to the chassis 10 and a baffle 52 connected to the output end of the driving device 51. The baffle 52 is provided with a number of through holes for oil fume gas to pass through. During the purification and dust removal process, the water vapor interception module 50 is started at the same time. After the driving device 51 is powered on, the baffle 52 is driven to rotate. After the water vapor molecules of the ozone water contact the baffle 52, they can drip along the baffle 52 and drip back onto the aeration net 21, while the oil fume gas can pass through the through holes and be discharged from the outlet 12 of the chassis 10.

[0041] Please refer to Figure 2 and Figure 3 The aeration module 20 of this embodiment also includes an aeration box 22 that is detachably fixed to the chassis 10. Specifically, the aeration box 22 can be fixed to the chassis 10 by screws. The aeration box 22 is connected from top to bottom. The aeration net 21 is detachably fixed to the lower end of the aeration box 22. Specifically, the aeration net 21 can be fixed to the aeration box 22 by screws. After the oil fume purification equipment has been used for a period of time, the aeration box 22 and the aeration net 21 need to be cleaned and maintained. In this embodiment, the aeration box 22 and the aeration net 21 are designed to be detachable structures, which can be convenient for staff to disassemble and clean them.

[0042] The formation of the ozone water vapor bubble film requires multiple debugging. In order to facilitate observation by the staff, this embodiment provides an inspection window 15 on the chassis 10. The inspection window 15 is located on one side of the aeration box 22. The inspection window 15 can be a transparent glass window. The staff can visually observe the formation of the ozone water vapor bubble film on the upper end of the aeration net 21 through the inspection window 15. Combined with the water flow control of the nozzle 31, a layer of ozone water vapor bubble film can be smoothly formed on the upper end of the aeration net 21.

Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of the present invention.
