Description

Technical Field

[0001] This utility model relates to the field of organic pollutant purification technology, specifically to an ultraviolet photocatalytic degradation device for organic pollutants. Background Technology

[0002] Ultraviolet (UV) photocatalytic degradation of organic pollutants utilizes UV light to irradiate a photocatalyst, causing it to generate strong oxidizing substances (such as hydroxyl radicals and superoxide radicals), which decompose organic pollutants into harmless CO2, H2O, and small-molecule inorganic compounds. This method is characterized by high efficiency, environmental friendliness, and no secondary pollution, and is widely used in the treatment of organic pollutants in wastewater and exhaust gases.

[0003] In the treatment of organic pollutants, ultraviolet (UV) photocatalytic degradation devices are required. Chinese utility model patent CN203095666U discloses a photochemical reaction experimental device, specifically an UV photocatalytic degradation device for organic pollutants used to study the photodegradation process of organic pollutants in surface water, groundwater, and industrial wastewater. The device includes a photodegradation reactor housing, a UV lamp source, a reaction vessel, and a magnetic stirrer. The UV lamp source includes at least two UV lamps controlled by independent UV lamp switches. The reaction vessel is equipped with a circulating cooling glass tube, which is a coil connected to an external cooling water pipeline. This utility model's device allows for controllable UV irradiation intensity, enabling control of the water reaction temperature within the reaction vessel and thus the reaction rate. The UV light directly irradiates the water being treated from the top, resulting in high UV absorption. It eliminates the need for quartz vessels and is cost-effective. This utility model is suitable for practical application by enterprises discharging organic pollutants or for industrial application through scale-up.

[0004] However, during use, this utility model cannot introduce oxygen into the organic pollutants, thus failing to achieve the aeration effect. Consequently, the organic pollutants cannot fully react with ultraviolet light, affecting the photocatalytic reaction rate and failing to meet production requirements. Therefore, an ultraviolet photocatalytic degradation device for organic pollutants is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an ultraviolet photocatalytic degradation device for organic pollutants. It has the advantage of improving the photocatalytic reaction rate and solves the problem that existing photocatalytic devices cannot introduce oxygen into organic pollutants, thus failing to achieve the aeration effect and causing the organic pollutants to not fully react with ultraviolet light, thereby affecting the photocatalytic reaction rate.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an organic pollutant ultraviolet photocatalytic degradation device, comprising a reaction vessel and a sealing cover plate fixedly connected to the top of the reaction vessel, wherein the top of the sealing cover plate is provided with an air-filling structure extending into its interior;

[0007] The inflation structure includes a rotating cylinder rotatably connected to the upper surface of the sealing cover plate. An inflation pipe extending into the top of the rotating cylinder is provided. A sealed bearing is fixedly connected inside the rotating cylinder. A drive shaft extending into the reaction vessel is fixedly connected to the bottom end of the rotating cylinder. An inflation head is fixedly connected to the outer surface of the drive shaft.

[0008] Furthermore, the inflation pipe passes through the sealed bearing and is fixedly connected to it, and a limit ring is fixedly connected to the outer surface of the inflation pipe.

[0009] Furthermore, a drive motor is fixedly connected to the top of the sealing cover, a transmission gear is fixedly connected to the output shaft of the drive motor, and a driven gear that meshes with the transmission gear is fixedly connected to the outside of the rotating cylinder.

[0010] Furthermore, a stirring blade is fixedly connected to the outside of the drive shaft, and a supercharger turbine is fixedly connected to the bottom end of the drive shaft.

[0011] Furthermore, a photocatalytic inner liner is fixedly connected inside the reaction vessel, an ultraviolet ring tube is fixedly connected to the outer surface of the photocatalytic inner liner, and a TiO catalytic coating is provided on the inner wall of the photocatalytic inner liner.

[0012] Furthermore, a feed pipe communicating with the inside of the reaction vessel is fixedly connected to the top of the sealing cover, and three support rods are fixedly connected to the bottom of the reaction vessel.

[0013] Furthermore, a discharge pipe connected to the bottom of the reaction vessel is fixedly connected to its interior, and a control valve is fixedly connected to the outside of the discharge pipe.

[0014] Compared with the prior art, this utility model provides an ultraviolet photocatalytic degradation device for organic pollutants, which has the following beneficial effects:

[0015] 1. This ultraviolet photocatalytic degradation device for organic pollutants, by setting up an air supply pipe and a rotating cylinder, and by setting up a drive shaft and an air supply head, can fill the reaction tank with external oxygen. By setting up a sealed bearing, it can achieve a sealing effect on the one hand, and on the other hand, it can make the rotating cylinder rotate smoothly. In turn, the drive motor can drive the booster turbine to rotate, further improving the reaction efficiency.

[0016] 2. This ultraviolet photocatalytic degradation device for organic pollutants, by setting up a photocatalytic inner tank and an ultraviolet ring tube, can carry out photocatalytic degradation of organic pollutants inside the photocatalytic inner tank. At the same time, with the addition of an aeration structure, it can greatly improve the photocatalytic reaction efficiency, making it impossible for organic pollutants to fully react with ultraviolet light. This solves the problem in existing photocatalytic devices that cannot introduce oxygen into the organic pollutants, thus failing to achieve the aeration effect and causing the organic pollutants to not fully react with ultraviolet light, thereby affecting the photocatalytic reaction rate.

[0024] It should be noted that the drive shaft 7 is externally fixedly connected to the stirring blades 12, and the bottom end of the drive shaft 7 is fixedly connected to the booster turbine 13.

[0027] Specifically, the ultraviolet loop tube 15 is a low-pressure mercury lamp, which has the advantages of low cost and wavelength matching with the best excitation light of TiO2. By setting up the photocatalytic inner liner 14 and the ultraviolet loop tube 15, the organic pollutants inside the photocatalytic inner liner 14 can be degraded by photocatalytic reaction. At the same time, with the air filling structure, the photocatalytic reaction efficiency can be greatly improved, so that the organic pollutants cannot fully react with ultraviolet light.

During the catalytic process, oxygen or air is introduced into the photocatalytic inner tank 14 through the air filling pipe 4. At the same time, the drive motor 9 is started to drive the stirring blades 12 and the supercharger turbine 13 to rotate, further improving the catalytic reaction rate. Then, it is discharged through the discharge pipe 18.
