Compared with the single ozone method, the deodorization device using ultraviolet light to decompose ozone to produce active oxygen for deodorization has better performance.

[0022] In an example of the utility model, the ultraviolet light source comprises an LED ultraviolet lamp and a low-pressure mercury lamp; wherein the light emission wavelength of the ultraviolet light source is 240nm-280nm, and the orientation angle of the ultraviolet light source is greater than 90°.

[0023] Compared with the prior art, the technical effects reached by adopting the technical scheme are: the orientation angle of the ultraviolet light source is greater than 90°, the residence time of the ultraviolet light in the active oxygen generating device is prolonged, so that the ozone generated by the ozone generating device can be completely decomposed into active oxygen by the ultraviolet light, and the production efficiency of the active oxygen is improved.

[0024] In an example of the utility model, the active oxygen generating device further comprises: a surrounding component, which surrounds the periphery of the ultraviolet light source.

DETAILED DESCRIPTION

[0047] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0048] In daily life, various odors such as the odor of adhesives and paints including building materials and furniture, tobacco odor, and spice odor during cooking often exist in indoor environment. Therefore, air purifiers capable of removing these odors and purifying air or air conditioning products equipped with air purification function are widely used. The deodorization method of the air purifier or the air conditioning product includes the following methods used alone or in combination: removing cooking fumes or tobacco smoke particles, etc. using high-performance filter screens; adsorbing odors using activated carbon or zeolite, etc.; and removing odors by reacting odor components with catalysts such as platinum and ozone. Among them, the reaction of ozone with odor components to change them into odorless components is the fundamental solution to odor. However, when the ozone concentration is high, it can be harmful to the human body, so when using ozone deodorization, the air purifier using ozone needs to be diluted to a harmless concentration under the action of an ozone decomposition catalyst such as manganese dioxide before being released into the indoor environment.

[0049] In addition, compared with the single ozone method, the deodorizing module using ultraviolet light to decompose ozone to generate active oxygen for deodorization has better performance. However, since the ultraviolet light has a large absorption coefficient and the intensity of the ultraviolet light is greatly affected by the installation position of the active oxygen generating device, it is easy to have the problem that the ozone is not fully decomposed by the ultraviolet light. In order to decompose all the ozone generated by the ozone generating device, the existing deodorizing device usually uses the method of increasing the number of ultraviolet light sources to achieve this.

[0050] However, the related art has at least one of the following problems: In order to decompose all the ozone generated by the ozone generating device, the deodorizing device in the prior art usually uses the method of increasing the number of ultraviolet light sources to achieve this, which reduces the utilization rate of the ultraviolet light generated by the ultraviolet light source, thereby increasing the production cost of the deodorizing device.

[0051] It should be noted that, as Figures 1 to 3 A deodorizing device 100 provided by an embodiment of the present application, Figure 1 The straight arrow outside the deodorizing device 100 in the figure indicates the flow direction of the air flow, Figure 3The straight arrow outside the active oxygen generating device 120 indicates the flow direction of the air fluid, and the straight arrow inside the active oxygen generating device 120 indicates the reflection direction of the ultraviolet light emitted by the ultraviolet light source; as Figure 4 The air conditioner 200 provided by the embodiment of the utility model, Figure 4 The straight arrow inside the air conditioner 200 indicates the flow direction of the air fluid.

[0052] To solve the above technical problems, as Figures 1 to 3 The utility model provides a deodorization device 100, deodorization device 100 is applied to air conditioner, deodorization device 100 includes ozone generator 110, active oxygen generating device 120, ultraviolet light source 130, ultraviolet light reflection material 140, specifically, ozone generator 110 sets up in the windward side of air conditioner, is used to generate ozone, active oxygen generating device 120 sets up in the leeward side opposite with windward side, is used to generate active oxygen, ultraviolet light source 130 sets up inside active oxygen generating device 120, is used to produce the ultraviolet light that decomposes ozone, ultraviolet light reflection material 140 sets up inside active oxygen generating device 120, is used to reflect ultraviolet light, wherein, the air flow direction in the air passage of air conditioner is from the windward side of deodorization device 100 blows to the leeward side of deodorization device 100, and the ozone generated by ozone generator 110 is decomposed by ultraviolet light, and active oxygen is generated as shown in (reaction formula 1):

[0053] Reaction formula 1: O3+ hν → O2( 1 Δ g ) + O( 1 D);

[0054] In reaction formula 1, h is Planck's constant, ν is light vibration number, O2( 1 Δ g ) is excited singlet oxygen molecule, O( 1 D) is singlet oxygen atom, and the wavelength λ of the ultraviolet light required by the deodorization device provided in the utility model example is less than 310 nm.

[0055] As can be obtained from reaction formula 1, ozone is decomposed into excited singlet oxygen molecule and singlet oxygen atom, wherein the singlet oxygen atom is also called atomic oxygen, which belongs to one kind of active oxygen and has very high reactivity. The generated active oxygen collides with gaseous odor molecules more quickly than ozone, oxidizes and decomposes the odor molecules to achieve deodorization.

[0056] Specifically, the present scheme is to set the ultraviolet light reflecting material 140 in the active oxygen generating device 120 to reflect the ultraviolet light emitted from the ultraviolet light source 130 through the ultraviolet light reflecting material 140, so that the irradiation of the ultraviolet light inside the active oxygen generating device 120 is more uniform, thereby improving the utilization rate of the ultraviolet light. Specifically, the ultraviolet light emitted by the ultraviolet light source 130 decomposes the ozone in the active oxygen generating device 120, and then is emitted through the ultraviolet light reflecting material 140. The ultraviolet light reflected by the ultraviolet light reflecting material 140 continues to decompose the ozone in the active oxygen generating device 120, thereby improving the utilization rate of the ultraviolet light. Further, the method of setting the ultraviolet light reflecting material 140 in the active oxygen generating device 120 provided by the present scheme compared with the method of increasing the number of ultraviolet light sources 130 in the prior art reduces the number of ultraviolet light sources 130, thereby reducing the production cost of the deodorizing device 100.

[0057] It should be noted that the ozone generation method of the ozone generating device 110 in the embodiments provided by the present application is not particularly limited and can include any one of the discharge method, 185nm vacuum ultraviolet light irradiation, etc. Among them, the discharge method can realize the miniaturization and light weight of the ozone generating device 110, and is easy to apply to the air conditioner. The discharge method includes corona discharge, silent discharge, and surface discharge, all of which can generate ozone, and the corona discharge and silent discharge are more easily applied. Further, if the ultraviolet light source 130 is a low-pressure mercury lamp or an LED ultraviolet lamp with a light-emitting wavelength less than 310nm, it can be used for ozone decomposition. The ozone absorption wavelength peak of the gas is 254nm. Therefore, among the ultraviolet light sources 130 with a light-emitting wavelength less than 310nm, the ultraviolet light source 130 with a light-emitting wavelength closest to 254nm is preferred. Among these light sources, it is recommended to use an LED ultraviolet lamp without harmful substances (such as no mercury), low power consumption, small size, and high installation freedom.

[0058] Further, as shown in Figure 3 , the ultraviolet light reflecting material 140 is provided with a plurality of ultraviolet light reflecting materials 140, and the plurality of ultraviolet light reflecting materials 140 are arranged in an array inside the active oxygen generating device 120; or the ultraviolet light reflecting material 140 is provided with a plurality of ultraviolet light reflecting materials 140, and the orthogonal projection of one ultraviolet light reflecting material 140 in the gravity direction at least partially overlaps with the orthogonal projection of another ultraviolet light reflecting material 140 in the gravity direction.

[0059] Specifically, the present scheme is to set the ultraviolet light reflecting material 140 in the active oxygen generating device 120 to reflect the ultraviolet light emitted from the ultraviolet light source 130 through the ultraviolet light reflecting material 140, so that the irradiation of the ultraviolet light inside the active oxygen generating device 120 is more uniform, thereby improving the utilization rate of the ultraviolet light. Specifically, the ultraviolet light emitted by the ultraviolet light source 130 decomposes the ozone in the active oxygen generating device 120, and then is emitted through the ultraviolet light reflecting material 140. The ultraviolet light reflected by the ultraviolet light reflecting material 140 continues to decompose the ozone in the active oxygen generating device 120, thereby improving the utilization rate of the ultraviolet light. Further, the method of setting the ultraviolet light reflecting material 140 in the active oxygen generating device 120 provided by the present scheme compared with the method of increasing the number of ultraviolet light sources 130 in the prior art reduces the number of ultraviolet light sources 130, thereby reducing the production cost of the deodorizing device 100.

[0060] Further, due to the improvement of the utilization rate of ultraviolet light and the uniformity of irradiation, the efficiency of ozone decomposition into active oxygen is improved, thereby enhancing the deodorization effect of the deodorization device 100 and more effectively removing odors and pollutants in the air.

[0061] Further, as shown in Figures 1 to 3 The ozone generation device 110 is provided with a first outlet on the side close to the active oxygen generation device 120. The active oxygen generation device 120 comprises a first inlet provided on the side of the active oxygen generation device 120 connected with the ozone generation device 110 and in communication with the first outlet, and a second outlet provided on the side of the active oxygen generation device 120 away from the ozone generation device 110, and the second outlet is oppositely arranged with the first inlet. The ultraviolet light source 130 is arranged in the active oxygen generation device 120 adjacent to the second side wall 122 of the first side wall 121 where the second outlet is located. As shown in the figure, the active oxygen generation device 120 has four second side walls 122.

[0062] Specifically, the arrangement of the first outlet and the first inlet in the present scheme ensures that the ozone generated by the ozone generation device 110 can directly enter the active oxygen generation device 120, reduces the escape of ozone in the transmission process, and improves the utilization rate of ozone.

[0063] The present scheme ensures that the ozone is immediately irradiated by ultraviolet light after entering the active oxygen generation device 120, rapidly decomposes into active oxygen, and enhances the effect of deodorization and air purification by arranging the ultraviolet light source 130 on the second side wall 122.

[0064] Further, as shown in Figure 3 The ultraviolet light source 130 comprises two or more, and the first plane where the optical axis 123 of each two oppositely arranged ultraviolet light sources 130 is located intersects with the second plane where the first inlet is located.

[0065] Specifically, the present scheme makes the ultraviolet light emitted by the ultraviolet light source 130 straight, and the ultraviolet light can also be reflected at various angles in the active oxygen generation device 120, thereby increasing the uniformity of the intensity of ultraviolet light in the active oxygen generation device 120, by arranging the first plane where the optical axis 123 of each two oppositely arranged ultraviolet light sources 130 is located intersects with the second plane where the first inlet is located.

[0066] Further, the ultraviolet light source 130 comprises at least one, and the number of the ultraviolet light sources 130 is determined according to the maximum production speed of ozone generated by the ozone generation device 110, the wavelength of the light source of the ultraviolet light source 130, and the light source radiation beam of the ultraviolet light source 130.

[0067] Specifically, the present scheme determines the number of the ultraviolet light sources 130 by the maximum production speed of the ozone generated by the ozone generator 110 and the light source wavelength of the ultraviolet light source 130 and the light source radiation beam of the ultraviolet light source 130, so that the ultraviolet light around the light axis 123 with the strongest light intensity of the ultraviolet light does not overlap each other in the active oxygen generator 120, thereby further increasing the uniformity of the intensity of the ultraviolet light in the active oxygen generator 120 and achieving the purpose of light quantity equalization.

[0068] Further, the number of light sources is set as f, the maximum production speed is set as b, the light source wavelength is set as λ, and the energy radiated per second by the light source is set as a. The calculation formula of the number of light sources is:

[0069] Formula 1: ;

[0070] wherein t is the time of the number of photons radiated by the ultraviolet light source 130, h is the Planck constant, c is the speed of light, M is the molecular weight of ozone, and the value of f is rounded up, N is the Avogadro constant (N = 6.0 x 1023 mol-1), b / M represents the number of moles of ozone produced when the ozone generator 110 works for t, hc / λ represents the energy of one photon of light radiated by one ultraviolet light source 130, which represents the number of moles of photons produced per second by one ultraviolet light source 130.

[0071] Specifically, the present scheme determines the number of the ultraviolet light sources 130 by the maximum production speed of the ozone generated by the ozone generator 110 and the light source wavelength of the ultraviolet light source 130 and the light source radiation beam of the ultraviolet light source 130, and the value of f is rounded up, so as to ensure that the ozone generated by the ozone generator 110 can be completely decomposed into active oxygen by the ultraviolet light, preventing high-concentration ozone from leaking into the room and causing harm to the human body. At the same time, it also avoids the waste of resources caused by using too many ultraviolet light sources 130.

[0072] In a specific embodiment, the ultraviolet light source 130 in the active oxygen generator 120 of the deodorization device 100 uses a LED ultraviolet lamp with a light source wavelength of 280 nm, the light source radiation beam of the LED ultraviolet lamp is 110 mW, and the orientation angle of the LED ultraviolet lamp is greater than 90 degrees. The maximum production speed of the ozone generated by the ozone generator 110 is set as 80 mg / h, the Planck constant is 6.6 x 10-34 Js, and the speed of light is 3.0 x 108 m / s. Therefore, the energy of one photon of light radiated by one LED ultraviolet lamp per second is hc / λ = 6.6 x 10-34 Js x 3.0 x 108 m / s ÷ (280 x 10-9 m) = 7.1 x 10-19 J;

[0073] The energy of the radiation beam of the LED ultraviolet lamp is a=110x10-3J, and the number of photons is 110x10-3J / 7.1x10-19J=1.5x1017;

[0074] Further, the number of moles of photons generated per second by one LED ultraviolet lamp is:

[0075] (i.e. 0.0009 mol / h);

[0076] Meanwhile, the molecular weight of ozone is 48 g / mol, and the number of moles of ozone generated by the ozone generator 110 per hour of operation is:

[0077]

[0078] The quantum yield of ozone irradiation of ultraviolet light to form singlet oxygen is almost 1, so the number of LED ultraviolet lamps required relative to the ozone generation speed per hour is:

[0079]

[0080] In the utility model, in order to satisfy that the ozone generation speed is less than the number of photons, two LED ultraviolet lamps should be used, so that the generated odor is completely reacted with ultraviolet light.

[0081] Further, the ultraviolet light source 130 includes an LED ultraviolet lamp and a low-pressure mercury lamp; wherein the light-emitting wavelength of the ultraviolet light source 130 is 240nm-280nm, and the orientation angle of the ultraviolet light source 130 is greater than 90°. The present scheme prolongs the residence time of ultraviolet light in the active oxygen generator 120 by setting the orientation angle of the ultraviolet light source 130 to be greater than 90°, thereby ensuring that the ozone generated by the ozone generator 110 can be completely decomposed into active oxygen by ultraviolet light, and improving the production efficiency of active oxygen.

[0082] Further, in order to prolong the service life of the ultraviolet light source 130, the ultraviolet light source 130 in the utility model embodiment is preferably an LED ultraviolet lamp.

[0083] Further, the active oxygen generator further includes a surrounding component (not shown in the figure), which surrounds the periphery of the ultraviolet light source 130.
