[0023] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0024] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and 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 direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.
[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0026] See also Figure 1-4 The utility model provides an oil fume purification device, which includes a purification box 21 for storing oil fume treatment liquid. The purification box is provided with an oil fume inlet 22 for oil fume to enter and an oil fume outlet 23 for oil fume to be discharged. A vibration component 28 located above the oil fume treatment liquid is provided in the purification box 21. The oil fume enters the purification box 21 through the oil fume inlet 22 and contacts with the oil fume treatment liquid to generate foam. The vibration component 28 increases the amount of foam by vibration to increase the contact area between the oil fume and the foam.
[0027] Specifically, the lower part of the purification box 21 is filled with oil fume treatment liquid, the oil fume inlet 22 is arranged at the lower part of the purification box 21 and corresponds to the oil fume treatment liquid, and a vibration component 28 is provided in the purification box 21, and the vibration component 28 is arranged above the oil fume treatment liquid and below the oil fume outlet 23.
[0028] Therefore, the oil fume purification device of the present invention arranges oil fume treatment liquid in the purification box 21, and arranges a vibration component 28 above the oil fume treatment liquid. The oil fume entering the purification box 21 first contacts with the oil fume treatment liquid located at the lower part of the purification box 21 to generate foam, and then carries the foam and blows upward to the vibration component 28 to make the vibration component 28 vibrate repeatedly to increase the amount of foam, thereby increasing the contact area between the oil fume and the foam, making the contact between the oil fume and the oil fume treatment liquid more complete, and then the oil fume is effectively purified through mutual inertial collision, retention, diffusion of fine particles and mutual coagulation and reaches the emission standard, thereby avoiding environmental pollution.
[0029] It is worth noting that the positions of the oil fume inlet 22 and the oil fume outlet 23 need to meet the requirements that the oil fume enters the oil fume treatment liquid in the purification box 21 from the oil fume inlet 22 to ensure that the oil fume treatment liquid absorbs and purifies the oil fume, and the absorbed and purified oil fume flows upward through the vibration component 28 and is discharged from the oil fume outlet 23.
[0030] In the present invention, the oil fume treatment liquid is a common oil fume purifier or oil fume absorbent on the market, and its main raw material is a purifier, which is generally an alkaline substance. The purifier stock solution has a certain corrosiveness, so it is mixed with water for use. The ratio of purifier to water depends on the corrosion resistance of the oil fume purification device and the purification requirements, and is not specifically limited here.
[0031] On the basis of the above structure, the oil fume inlet 22 is provided with a pipeline 4, which extends into the purification box 21 through the oil fume inlet 22, and the oil fume outlet of the pipeline 4 faces the bottom of the purification box 21. The oil fume entering through the oil fume inlet 22 flows toward the bottom of the purification box 21 after being discharged from the pipeline 4, and then flows upward, so that the oil fume can be fully absorbed and purified by the oil fume treatment liquid, thereby improving the oil fume purification efficiency.
[0032] The fume treatment liquid can be poured into the purification box 21 after being prepared externally, but there is a disadvantage of cumbersome operation. In the utility model, the purification box 21 is provided with a water inlet 24 for water supply and a discharge port 25 for drainage, the discharge port 25 is provided at the bottom of the purification box 21, and the water inlet 24 is provided at the side of the purification box 21. The fume purification device also includes a purifier box 5 for storing purifiers, and the purifier box 5 is connected to the purification box 21.
[0033] Among them, the water inlet 24 is used to introduce water into the purification box 21, and the purifier is introduced from the purifier box 5 into the purification box 21, so as to achieve the mixing of water and purifier. The amount of water and purifier introduced into the purification box 21 is operated according to the ratio of the two, and the oil fume treatment liquid needs to be prepared before the oil fume purification. The oil fume treatment liquid can be manually prepared, which may affect the accuracy of the ratio. In the utility model, the oil fume purification device is provided with a control module to realize the automatic preparation of water and purifier through the control module to ensure the accurate ratio of water and purifier.
[0034] The water inlet 24 is provided with a valve, and the pipeline connecting the purifier box 5 and the purifier box 21 is also provided with a valve. The two valves are electrically connected to the control module to open the valves during the preparation and close the valves after the preparation is completed. The purifier box 5 is also provided with a purifier addition port 51, so that the purifier is added to the purifier box 5 through the purifier addition port 51.
[0035] After the oil fume treatment liquid has absorbed and purified the oil fume for a long time and many times, it will contain a large amount of impurities, and its absorption and purification capacity will be reduced. It needs to be discharged from the purification box 21 to replace the new oil fume treatment liquid. The discharge port 25 is used to discharge the oil fume treatment liquid that has absorbed and purified the oil fume for a long time and many times. The discharge port 25 is provided with a valve, and the valve is electrically connected to the control module. During the operation of the oil fume purification device, the control module controls the valve to be closed. When the oil fume treatment liquid that has absorbed and purified the oil fume for a long time and many times needs to be discharged, the control module controls the valve to be opened.
[0036] In addition, the oil fume purification device of the utility model further includes a circulation loop 26, the liquid inlet end of the circulation loop 26 is connected to the bottom of the purification box 21, and the liquid outlet end of the circulation loop 26 is connected to the top of the purification box 21 and faces the vibration assembly 28. The circulation loop 26 is arranged outside the purification box 21, and is provided with a driving pump to provide power. The oil fume treatment liquid flows out from the bottom of the purification box 21 to the circulation loop 26, and then flows back into the purification box 21 from the top of the purification box 21 through the circulation loop 26. The oil fume flowing to the bottom of the purification box 21 through the oil fume inlet 22 first contacts the oil fume treatment liquid located at the bottom of the purification box 21 to generate foam, and then carries the foam and blows upward to the vibration assembly 28 to make the vibration assembly 28 vibrate repeatedly to increase the amount of foam, thereby increasing the contact area between the oil fume and the foam, so that the oil fume and the oil fume treatment liquid contact more fully. At the same time, the oil fume treatment liquid flowing back from the top of the purification box 21 impacts the vibration component 28 again, increasing the vibration amplitude of the vibration component 28, thereby increasing the amount of foam generated, making the contact between the oil fume and the purifier more complete. In addition, the oil fume treatment liquid flowing back from the top of the purification box 21 can also impact, absorb, and purify the oil fume again, and then discharge the oil fume from the oil fume outlet 23. The oil fume is absorbed and purified twice by the oil fume treatment liquid in the purification box 21, and the vibration of the vibration component increases the contact area between the oil fume and the purifier, further improving the oil fume purification efficiency.
[0037] On this basis, a spray head 27 is provided at the other end of the circulation loop 26, the spray head 27 faces the vibration assembly 28, and the spray head 27 extends from the top of the purification box 21 to the inside of the purification box 21. The oil fume treatment liquid flows out from the bottom of the purification box 21 to the circulation loop 26, and then is sprayed back into the purification box 21 from the top of the purification box 21 through the spray head 27 through the circulation loop 26. The impact force of the spray head 27 is greater, and it can disperse and spray the oil fume treatment liquid, which not only further increases the amount of foam generated, but also disperses and strongly impacts the particulate matter in the oil fume and is absorbed by the oil fume treatment liquid and falls into the bottom of the purification box 21, so that the oil fume is effectively purified.
[0038] Furthermore, the water spray port of the spray head 27 is connected to a plurality of nozzles, which are spaced apart and directed toward the vibration assembly 28. The arrangement of the plurality of nozzles allows the oil fume treatment liquid flowing back from the top of the purification box 21 to be sprayed more evenly, further improving the purification effect.
[0039] Since the mixture of the purifier and water flowing back from the top of the purification box 21 needs to flow to the bottom of the purification box 21, there is a gap between the vibration component 28 and the inner wall of the purification box 21. And / or, the side wall of the vibration component 28 is fixedly connected to the inner wall of the purification box 21, and the vibration component 28 is provided with a plurality of through holes 281 running longitudinally, so that the oil fume treatment liquid flows to the bottom of the purification box 21 through the plurality of through holes 281, and the through holes 281 can be used for the oil fume to carry the oil fume treatment liquid and foam through.
[0040] In the present invention, the vibration component 28 can be an elastic screen-like structure. When the oil smoke blows toward the vibration component 28, it vibrates itself to make the oil smoke treatment liquid generate a large amount of foam.
[0041] Alternatively, the vibration assembly 28 includes a carrier box 282 and a plurality of vibration balls (not shown in the figure), the carrier box 282 is provided with a plurality of through holes 281 therethrough, the plurality of vibration balls are vibratingly arranged in the carrier box 282, and the plurality of vibration balls vibrate when the oil smoke blows. Based on cost considerations, the vibration balls of the utility model can be plastic balls.
[0042] Specifically, the carrying box 282 includes a box body 2821 and a cover plate 2822. The box body 2821 is a cavity structure with an opening facing upward. The bottom plate of the box body 2821 is provided with a plurality of through holes 281, and a plurality of vibration balls can be vibratedly arranged in the box body 2821. The cover plate 2822 is provided on the box body 2821 to prevent the plurality of vibration balls from vibrating out of the box body 2821. The cover plate 2822 is provided with a plurality of through holes 2823. Thus, by providing a plurality of vibration balls in the box body 2821 and covering the cover plate 2822, the vibration of the vibration balls can be limited to prevent the vibration balls from being separated from the box body 2821 and affecting the vibration effect, thereby affecting the foam generation effect. The through holes 2823 facilitate the passage of the fume carrying the fume treatment liquid and the foam, and the collision of the vibration balls with the cover plate 2822 can further increase the foam production.
[0043] Since the oil fume carrying the oil fume treatment liquid and foam will generate a large amount of foam after passing through the vibration component 28, it will pollute the environment if it is discharged directly. Therefore, a defoaming member 29 is provided in the purification box 21 corresponding to the oil fume outlet 23. The defoaming member 29 includes a plurality of blades 291, and the plurality of blades 291 are arranged at an angle and spaced laterally. When the oil fume carrying the oil fume treatment liquid and a large amount of foam passes between two adjacent blades 291, it will hit the inclined blades 291 to remove part of the foam, thereby reducing the pressure of removing the foam in the subsequent process.
[0044] In this embodiment, the blade 291 includes an upper inclined section 2911, a lower inclined section 2912 and a connecting section 2913. The upper inclined section 2911 and the lower inclined section 2912 are connected by the connecting section 2913. The angle between the upper inclined section 2911 and the connecting section 2913 and the angle between the lower inclined section 2912 and the connecting section 2913 do not exceed 90°. That is, the angle between the upper inclined section 2911 and the connecting section 2913 is an acute angle or a right angle, and the angle between the lower inclined section 2912 and the connecting section 2913 is also an acute angle or a right angle. When the oil smoke carries the oil smoke treatment liquid and a large amount of foam through the defoaming member 29, it will experience multiple collisions, and the foam removal effect is better.
[0045] In addition to the above-mentioned oil fume purification device, the utility model also provides a range hood, which includes the above-mentioned oil fume purification device. The above-mentioned oil fume purification device is used in the range hood, and the oil fume sucked by the range hood is purified by the oil fume purification device and then discharged into the environment. After passing through the range hood, the oil fume is effectively purified and meets the emission standards, avoiding emission pollution to the environment.
[0046] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
