Problems solved by technology

This is only to change people's sense of smell, but it cannot essentially remove harmful substances in the gas and kill bacteria. Moreover, the combination of sprayed chemicals and odorous gas produces new pollutants, which are ignored by people, and the cost is also high.

Embodiment 1

[0038] see Figure 1-Figure 10 , as shown in the legend therein, a photocatalytic sterilization and deodorization device for removing bacteria and odors in the air, including:

[0039] A case 1 is provided with an air intake 11, an exhaust port 12, three board frames 13, two rows of light frames (each row of light frames includes three light frames 14), a fan frame 15 and a case door 16;

[0040] A sterilizing and deodorizing mechanism, including a photocatalytic plate and a catalytic light source, the photocatalytic plate is a mesh plate 2 coated with a photocatalyst layer on the surface of one or more layers; the mesh plate 2 is detachably connected to the plate frame 13 and divide the inner chamber of the cabinet 1 into an air inlet chamber 17 corresponding to the air inlet 11 and an air outlet chamber 18 corresponding to the exhaust port 12; the catalytic light source is the ultraviolet lamp 3, and the ultraviolet lamp 3 Arranged on one or both sides of the mesh plate 2 a...

Embodiment 2

[0059] All the other are identical with described embodiment 1, and difference is that above-mentioned photocatalytic sterilization deodorization device is at least two, and this sterilization deodorization device forms air convection and circulation, adopts more than two photocatalytic sterilization devices, makes gas flow in the toilet Convection and circulation are formed inside to prevent dead ends.

Embodiment 3

[0061] The rest is the same as the first embodiment, except that the above-mentioned variable speed axial flow fan 4 is arranged in the air intake chamber 17 .

[0062] Beneficial effects of adopting the above technical solutions: Using advanced photocatalysis technology, using the extremely strong oxidation function of photocatalysis, the harmful substances in the gas in the toilet, including ammonia, sulfide and organic volatile gases, can be efficiently oxidized into harmless substances, The deodorization rate can reach more than 99%, and it can kill almost all bacteria and make it impossible to regenerate; 2. Use a mesh plate coated with a photocatalyst layer on the surface to make the contact surface between the treated air and the photocatalyst And the contact time is greatly increased, thereby improving the photocatalytic efficiency; 3. The automatic control of the photocatalytic sterilization and deodorization device can be realized by adopting a control system with a m...

Abstract

The invention discloses a photocatalysis sterilization deodorization device which is used for eliminating bacteria and odor in the air, and comprises a chassis, a sterilization deodorization mechanism, an exhaust mechanism and a control system, wherein the sterilization deodorization mechanism comprises a photocatalysis plate and a catalysis light source, the catalysis light source is arranged on one side or two sides of the photocatalysis plate and illuminates a light catalyst layer; the exhaust mechanism is used for enabling the air to sequentially flow by an air inlet cavity, the photocatalysis plate and an air outlet cavity to reach an exhaust port from an air suction port; and the control system is respectively electrically connected with the catalysis light source and the exhaust mechanism. By adopting the advanced photocatalysis technology and utilizing the strong oxidation function of the photocatalysis, harmful substances including ammonia, sulfide and organic volatize gases in the air of a toilet can be high efficiently oxidized into harmless substances, the deodorization rate can reach more than 99 percent and all bacteria can be basically killed and cannot be recovered.

Description

technical field [0001] The invention relates to a sterilization and deodorization device, in particular to a photocatalytic sterilization and deodorization device. Background technique [0002] With the acceleration of urbanization and the development of tourism in my country, public toilets have become an indispensable infrastructure in cities. Insufficient sexual awareness or poor management lead to the spread of odor and bacteria in and around the toilet. Especially in densely populated areas, such as railway waiting rooms, long-distance bus stations, comprehensive service buildings, service units, hospitals, tourist areas and downtown areas, there are frequent crowds entering the toilet. If there are no effective environmental protection measures, the pollution will be even greater. serious. The pollution of the toilet not only endangers people's health, but also directly affects the appearance and civilization of the city. According to relevant reports, my country's t...
