Description

Technical Field

[0001] The invention relates to an air treatment system. Background Art

[0002] The current air treatment systems generally include the following: 1. Filtering harmful substances in the air through a filter. The filtering method is just to store the harmful substances in the filter, and the harmful substances are slowly released on the filter, forming secondary pollution; 2. On the basis of the former, ultraviolet lamps or electrodes are added to first photocatalyze or ionize the harmful substances before entering the filter, and the filter further filters the untreated air. It still has the shortcomings of the above-mentioned "first" type; 3. On the basis of the above-mentioned "second" type, a water curtain is also installed in front of the ultraviolet lamp, so that part of the harmful substances in the air are mixed into the water. This structure also has the shortcomings of the above-mentioned "first" type, but the impact is slower than the first two. However, since the intensity of ultraviolet light is greatly weakened after it is irradiated into the inside of the water curtain, the photocatalytic and strong oxidation capabilities are reduced, so that the water in the water curtain is constantly polluted but cannot be cured, and even the problem of sewage treatment is derived. 4. Install a spray in front of the UV lamp, but the water mist of the spray does not enter the UV irradiation area. The role of the spray is only to absorb part of the pollutants in the air into the water, and then the air still carrying pollutants enters the UV irradiation area for photocatalysis. However, due to the limited UV irradiation capacity, the photocatalytic effect is poor.

[0003] In addition, the air treatment systems currently on the market mainly deal with pollutants in the air, but there is no good solution for dealing with some stubborn odors (for example, the tar smell and "smoke smell" in the air). Summary of the invention

[0004] The purpose of the present invention is to provide an air treatment system with a simple and reasonable structure, good air purification effect and good odor treatment effect, so as to overcome the shortcomings of the prior art.

[0005] The object of the present invention is achieved in that:

[0006] An air treatment system includes a housing, wherein the housing is provided with an air inlet and an air outlet, and the air inlet and the air outlet are connected through an air duct; the housing is also provided with a fan for allowing air to flow through the air duct, and is characterized in that: an atomization zone, a photocatalytic zone and a wastewater collection zone are sequentially provided between the corresponding air inlet and the air outlet in the air duct, and the atomization zone, the photocatalytic zone and the wastewater collection zone are sequentially connected. In this structure, the water mist generated by the atomization zone contacts the air to a certain extent, so that a part of the air and the pollutants in the air are integrated into the water mist, and the water mist enters the photocatalytic zone, and the ozone generated by the photocatalytic zone contacts the water mist, so that the pollutants in the water mist are strongly oxidized. In addition, after the photocatalytic zone irradiates the water mist, the water mist refracts the light, so that the range of the light increases geometrically, bringing a stronger strong oxidation effect to the air that has not contacted the water mist, thereby making the photocatalytic effect stronger, more thorough and more comprehensive.

[0007] The purpose of the present invention can also be solved by the following technical measures:

[0008] As a more specific solution, the atomization area is provided with an atomization chamber, an atomizer and a water supply tank for providing water to the atomizer. The atomizer is arranged in the atomization chamber, and the atomization chamber is connected with the air inlet and the photocatalytic area. The atomizer atomizes the water source provided by the water supply tank to form countless tiny mist beads. When the treated air passes through the atomization chamber filled with tiny mist beads, the tiny mist beads are contaminated (the tiny mist beads are in contact with the air) and continue to flow with the air to the photocatalytic area.

[0009] As a further solution, the photocatalytic zone includes a UV catalytic chamber and a UV lamp, and the UV catalytic chamber is connected to the atomization chamber. When the UV lamp is working, the ultraviolet light (UV) is emitted, and the polluted tiny mist beads contact the surface of the UV lamp. The ultraviolet light irradiates the tiny mist beads, and then refracts and reflects to produce N times of ultraviolet light with no dead angle (or almost no dead angle), so as to achieve photocatalysis of the treated air.

[0010] In addition, the treated air can basically come into contact with tiny mist beads when passing through the UV catalytic chamber, because ultraviolet light irradiates the air to produce ozone, and the ozone strongly oxidizes the air pollutants in the tiny mist beads after contacting the tiny mist beads; and because the tiny mist beads are roughly spherical, they have a certain refraction and reflection effect on ultraviolet light, so that ozone is evenly distributed in the photocatalytic area, thereby strongly oxidizing the pollutants in the treated air in all directions, thereby forcibly treating the pollutants and odors in the treated air. In addition, the treated air does not directly contact the UV lamp, but the tiny mist beads are in contact with the UV lamp. The oil and pollutants in the treated air do not adhere to the UV lamp, ensuring that the UV lamp continuously and efficiently releases ultraviolet light.

[0011] As a further solution, the UV catalytic chamber is long, and the UV lamp extends along the length of the UV catalytic chamber; one end of the UV catalytic chamber is connected to the atomizing chamber, and the other end of the UV catalytic chamber is connected to the wastewater collection area. The UV catalytic chamber and the UV lamp are designed to be long, so that the tiny mist droplets generated by the atomizing chamber are more fully oxidized.

[0012] As a further solution, the UV lamps are provided with more than two, and a certain gap is provided between the UV lamps to allow air and water mist to pass through. By providing more than two UV lamps, the illumination area is more comprehensive and the air treatment effect is better.

[0013] As a further solution, the wastewater collection area includes a water-throwing device, an air-collecting box and a wastewater collection box. The water-throwing device includes a water-throwing wheel and a water-throwing driving motor. The water-throwing driving motor is connected to the water-throwing wheel in a driving manner. The water-throwing wheel is arranged in the air-collecting box. The air-collecting box is provided with an air-collecting port, an air-exhausting port and a water-draining port. The air-collecting port is connected to the UV catalytic chamber, the air-exhausting port is connected to the air-outlet, and the water-draining port is connected to the wastewater collection box. Since the tiny mist droplets are very light and can float with the air flow, the tiny mist droplets treated in the photocatalytic zone contain oxides, carbides and ozone (a small part of ozone), etc. Ozone can be released from them. After the oxides and carbides evaporate with the tiny mist droplets, the oxides and carbides form substances floating in the air, so the tiny mist droplets treated in the photocatalytic zone need to be treated. To this end, this scheme uses a water wheel to separate the water vapor in the tiny mist droplets after being treated in the photocatalytic zone. Specifically, when the tiny mist droplets pass through the high-speed rotating water wheel, the water and ozone are separated, and solid substances such as oxides and carbides contained in the water fall into the wastewater collection box together.

[0014] As a further solution, the water wheel is a wheel body with a plurality of pores. The water wheel is essentially the oil fume separation wind wheel used in some current range hoods, which can be purchased directly. At the same time, the water wheel can refer to the structure of a high-efficiency oil fume separator disclosed in Chinese patent number CN201320428427.2 on January 8, 2014, which includes a wind wheel and a steel wire. The wind wheel is composed of a wheel frame, a wheel hub and an arc-shaped wind blade. Therefore, the structure of the water wheel is not described in detail here.

[0015] As a further solution, the wind collecting box includes an outer box body and an inner cover, the bottom and top of the outer box body are respectively provided with a wind collecting port and an air outlet, and the top of the wind collecting port is provided with a water retaining plate; the inner cover is arranged in the outer box body and covers the wind collecting port and the water retaining plate, a water throwing chamber is formed between the inner cover and the inner wall of the outer box body, the top and the lower end of the inner cover are respectively provided with an upper opening and a lower opening, the water throwing wheel is located in the water throwing chamber and is located between the air outlet and the upper opening; the drain port is arranged at the bottom of the outer box body and is connected to the water throwing chamber. Some tiny mist beads are still floating after passing through the water throwing wheel, and the floating tiny mist beads pass through the lower opening between the bottom of the inner cover and the bottom wall of the outer box body and pass through the upper opening of the inner cover again to enter the water throwing wheel, and the cycle continues, and finally most of the tiny mist beads are thrown into the water throwing chamber, and the ozone in the tiny mist beads is released. The tiny mist beads are thrown to the wall of the water throwing chamber, and when the tiny mist beads on the wall of the water throwing chamber gather into large volume water droplets, they flow downward and finally fall into the wastewater collection box through the drain port. The gas (such as the above-mentioned ozone) in the tiny mist droplets after contacting the water wheel flows toward the air outlet through the pores. Users can centrally treat the wastewater in the wastewater collection box.

[0016] As a further solution, a filter chamber is provided between the wastewater collection area and the air outlet in the air duct, and a deozonation filter is provided in the filter chamber. After the residual ozone passes through the deozonation filter, clean and odorless air is finally discharged from the air outlet.

[0017] The above-mentioned deozonation filter is a well-known product in the art, and its structure is not described in detail here. For details, please refer to the Chinese patent CN200520053754.X on May 17, 2006, which discloses an activated carbon deozonation filter, in which a deozonation layer is arranged on the inner surface or outer surface of a porous substrate. And the Chinese patent CN200510032799.3 on October 12, 2005 discloses a method for manufacturing an activated carbon deozonation filter, in which activated carbon, a dispersant and a catalyst are combined on a porous substrate, and then an adhesive is added, and then a flame retardant dissolved in water is made.

[0018] As a further solution, a positive pressure chamber is provided between the filter chamber and the wastewater collection area in the air duct, and the fan sucks air from the wastewater collection area and blows it to the positive pressure chamber. The positive pressure chamber has a relatively high pressure, and the air to be discharged can be forcibly blown into the filter chamber.

[0019] The beneficial effects of the present invention are as follows:

[0020] (1) This air treatment system mixes the treated air with water mist and then performs photocatalytic treatment. The catalytic effect of pollutants in the treated air is doubled, and the water mist treated in the photocatalytic area is collected and treated (the water mist contains oxides and carbides);

[0021] (2) The residual ozone in the water mist after the photocatalytic treatment in this air treatment system can be filtered by the ozone removal filter in the filter chamber, thus ensuring that the air discharged from the outlet is odorless;

[0022] (3) The filter chamber of this air treatment system uses ozone decomposition materials to decompose residual ozone. BRIEF DESCRIPTION OF THE DRAWINGS
