Description

Technical Field

[0001] The utility model relates to the technical field of ecological environment restoration, in particular to a photocatalytic algae removal device based on ultraviolet rays. Background Art

[0002] Eutrophication of water bodies is a common problem around the world. It is mainly due to excessive fertilization, wastewater discharge and other reasons that lead to excessive nutrient concentrations in water bodies, thereby promoting the growth of algae. The large-scale growth of algae not only consumes oxygen in the water, causing water hypoxia, but also releases toxic substances, causing serious damage to the aquatic ecosystem. Traditional algae removal methods mainly include chemical agents, biological control and physical methods, but these methods have problems such as high cost, complex operation and great impact on water quality. Therefore, exploring new algae removal methods has become an urgent need. As a green and pollution-free technology, photocatalytic technology has become a new technology with great application prospects in the field of deep sewage treatment. It has the advantages of mild reaction conditions, simple reaction equipment, low secondary pollution, easy operation and control, easy availability of catalytic materials and low operating costs. It is hailed as the most promising advanced oxidation technology for environmental purification in the 21st century.

[0003] However, the application of photocatalytic technology in wastewater treatment is still at the laboratory stage. The main reason is that the research and development of photocatalytic reactors is backward. The existing photocatalytic reactors generally have problems such as small photocatalytic action area, low light energy utilization, poor mass transfer effect, difficulty in replacing catalysts, and the inability to maximize the performance of photocatalysts. Therefore, its promotion and practical application in industry are seriously restricted.

[0004] Chinese Patent Publication No. CN217148647U discloses an algae removal device based on photocatalytic degradation. When water flows through the blades, the blades are driven to rotate slowly, ensuring that the algae are fully and evenly attached to the blades under the action of the water flow and complete the photocatalytic reaction. After the reaction is completed, the filler on the blades is fully in contact with the water surface, achieving the purpose of removing degradation products. In addition, the photocatalyst is tightly bonded to the filler, overcoming the problem of difficult photocatalyst recovery.

[0005] However, in actual use, the above structure uses natural light for photocatalysis, and the natural photocatalytic conditions are easily affected by fluctuations in weather factors. Specifically, in clear and cloudless weather, the solar radiation is strong, and the device can fully absorb and utilize light energy to promote the activity of the photocatalyst, thereby effectively improving the algae removal efficiency and achieving rapid purification of the water body. However, once encountering weather conditions such as continuous rain, haze, or shortened daylight hours, the intensity and irradiation time of natural light will drop significantly, which directly leads to insufficient light energy required for the photocatalytic reaction, and the activity of the photocatalyst is inhibited, which in turn makes the algae removal efficiency unstable, and may even be significantly reduced, making it difficult to meet the continuous and stable algae removal needs.

[0026] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] See also Figure 1 and Figure 2 As shown, a photocatalytic algae removal device based on ultraviolet rays includes a shell 1, a through groove 11 arranged in the middle of the shell 1, a pretreatment channel 2 arranged in the shell 1 and used for filtering sewage, and a core reaction component 3 arranged in the pretreatment channel 2 for treating algae attached to the sewage. The core reaction component 3 includes an ultraviolet lamp tube 31 arranged in the core reaction component 3 and a UV reflector 32 wrapped around the outside of the core reaction component 3, and also includes a plurality of detachable monomers 4 arranged in the through groove 11 and a plurality of metal meshes 41 arranged on the detachable monomers 4. The number of detachable monomers 4 is preferably eight, and each detachable monomer 4 is provided with five layers of metal mesh 41 loaded with photocatalysts.

[0028] When treating algae in the water area within the core reaction component 3, the water can fully contact the photocatalyst loaded on the metal mesh 41 during the flow of water, thereby improving the degradation efficiency of the algae. Placing the photocatalyst on the metal mesh 41 also makes it easy to replace and recycle the photocatalyst. Through the detachable monomer 4, the combination of disassembly and installation can be carried out according to the different water treatment volumes and the different degrees of eutrophication of the water body. The treatment range is wide. The pretreatment channel 2 is preferably made of metal material, and the higher thermal efficiency of the metal material can be used to increase the temperature of the water body. When the ultraviolet lamp tube 31 irradiates, the UV reflector 32 effectively reflects the light emitted by the ultraviolet lamp tube 31, ensuring that the ultraviolet light is evenly irradiated on the metal mesh 41, thereby improving the photocatalytic efficiency.

[0029] See also Figure 1 and Figure 2As shown, the core reaction component 3 also includes a water inlet 33, a water outlet 34 and a filter device 35; the water inlet 33 is located at the water inlet end of the pretreatment channel 2, so that the water flows into the pretreatment channel 2 and then passes through the core reaction component 3; the water outlet 34 is arranged at the water outlet end of the core reaction component 3; the filter device 35 is arranged on the water inlet 33, and the filter device 35 is used to collect algae in the water.

[0034] Since the core reaction component 3 is made of light-transmitting material, when the battery 37 supplies power to the ultraviolet lamp 31 , the ultraviolet lamp 31 can irradiate light onto the metal mesh 41 and cooperate with the photocatalyst to improve the degradation efficiency of algae.

[0035] See also Figure 4-Figure 6 As shown, the detachable unit 4 includes a placement plate 42 for placing the metal mesh 41 and a quick-release mechanism 5 for quickly installing and removing the metal mesh 41 on the placement plate 42; the quick-release mechanism 5 includes a placement limit groove 51, a docking block 52, a docking groove 53 and a positioning bolt 54; the placement limit groove 51 is opened on the placement plate 42, and the placement limit groove 51 is used to support the metal mesh 41; the docking block 52 is set on the placement plate 42; the docking groove 53 is opened on the light-transmitting plate 38 and is used to engage with the docking block 52; the positioning bolt 54 is threadedly installed on the docking block 52 and the docking groove 53.

[0036] When it is necessary to quickly install the metal mesh 41 and the detachable unit 4 on the light-transmitting plate 38, first insert the placement plate 42 into the docking groove 53 provided on the light-transmitting plate 38 through the docking block 52, and then rotate it to the light-transmitting plate 38 and the docking block 52 through the positioning bolt 54, so that the placement plate 42 can be quickly installed on the light-transmitting plate 38. When it is necessary to quickly install the metal mesh 41 on the placement plate 42, the metal mesh 41 is processed and placed on the placement limiting groove 51 provided on the placement plate 42. At this time, the metal mesh 41 can be quickly placed on the placement limiting groove 51. At this time, the metal mesh 41 can be preliminarily limited, so that the placement plate 42 can be quickly installed on the light-transmitting plate 38. The combination of disassembly and installation can be carried out according to the different water treatment volumes and the different degrees of eutrophication of the water body, and the treatment range is wide.
