Description

Technical Field

[0001] This utility model belongs to the technical field of water quality treatment experimental equipment, specifically relating to a far-ultraviolet light water purification device. Background Technology

[0002] Excessive algae growth in water bodies can negatively impact the aquatic ecosystem, causing oxygen depletion and death of aquatic plants and animals, leading to water quality deterioration. Some algae, especially cyanobacteria, release toxic substances such as algal toxins and hydrogen sulfide when their cells are damaged or aging, directly harming aquatic animals. Therefore, inhibiting and eliminating algae plays a crucial role in water purification.

[0003] Microcystis aeruginosa is a dominant algal species in cyanobacterial blooms. Its massive proliferation not only pollutes drinking water and landscape water bodies, increasing the cost of water treatment and maintenance, but also disrupts the aquatic ecosystem. Furthermore, Microcystis aeruginosa produces and releases microcystin into water bodies. Microcystin can accumulate in aquatic organisms through the food chain and food web, exerting toxic effects on organisms in the aquatic environment. In addition, microcystin can enter the human body through various pathways, causing health risks such as tumors.

[0004] Traditional ultraviolet (UV) algae-killing devices pose significant health risks, requiring personnel to avoid the area during use. Furthermore, accidents during operation are difficult to handle promptly, making them highly dangerous. Far-ultraviolet light with a wavelength of 222 nm is effective at killing algae and is essentially harmless to humans. However, the technology for algae killing with 222 nm far-ultraviolet light is not yet fully developed; therefore, it is necessary to design an experimental device for testing and optimizing the algae-killing effect of 222 nm far-ultraviolet light. Summary of the Invention

[0005] The purpose of this invention is to provide a far-ultraviolet light water purification device that can be used to conduct far-ultraviolet algae removal experiments, thereby promoting the development of a far-ultraviolet algae removal process that is efficient, harmless to the human body, and not easily affected by the external environment.

[0006] In a first aspect, this utility model provides a far-ultraviolet light water purification device, which includes a housing, an algae-carrying container, and an ultraviolet irradiation component installed in the housing. The ultraviolet irradiation component includes an ultraviolet lamp and a collimating tube. The ultraviolet lamp is installed at the top of the inner cavity of the housing and faces the top opening of the algae-carrying container. The collimating tube is fixed to the inner cavity of the housing and is located between the ultraviolet lamp and the algae-carrying container.

[0007] Preferably, the ultraviolet irradiation assembly further includes a light-shielding cover. The light-shielding cover is disposed at the top opening of the housing. The ultraviolet lamp is installed inside the light-shielding cover.

[0008] Preferably, the ultraviolet lamp is a 222 nm far-ultraviolet lamp tube, which is installed on the inside of the light-shielding cover.

[0009] Preferably, the bottom of the light-shielding cover is provided with a quartz plate. The quartz plate is located between the ultraviolet lamp and the collimator.

[0010] Preferably, the collimating tube is aligned with the algae-carrying container and has the same cross-sectional profile.

[0011] Preferably, it also includes a stirring component for promoting the flow of water within the algae-carrying container.

[0012] Preferably, the stirring assembly includes a magnetic stirrer and a magnetic stirring rod. The magnetic stirrer is installed at the bottom of the inner cavity of the housing. The magnetic stirring rod is placed inside the algae-carrying container. The algae-carrying container is positioned on the magnetic stirrer.

[0013] Preferably, a temperature control component is also included. The temperature control component includes a thermostatic bath. The thermostatic bath has an inlet and an outlet for circulating the liquid medium. The thermostatic bath is placed on a magnetic stirrer. The algae carrier container is placed inside the thermostatic bath.

[0014] Preferably, the side of the housing has an opening. A closing door is rotatably connected to one side of the opening.

[0015] Preferably, the box is rectangular.

[0016] The beneficial effects of this invention are:

[0017] This invention incorporates a constant-temperature bath, which maintains a stable water temperature in the algae-carrying container by circulating a liquid medium at a constant temperature. This prevents temperature fluctuations from affecting algae killing efficiency and experimental accuracy. Furthermore, this invention introduces a magnetic stirrer to agitate the algae suspension, ensuring uniform light exposure for the algae in the water. This allows for the determination of the impact of different water flow conditions on the algae-killing efficiency of far-ultraviolet light.

[0018] The far-ultraviolet (FUL) water purification device provided by this invention is used to test the algae-inhibiting effect of 222 nm wavelength FUL. Compared with traditional UV algae-killing equipment, 222 nm wavelength FUL not only kills algae cells more efficiently but is also virtually harmless to humans, making it suitable for use in human environments and contributing to research on FUL algae eradication. Furthermore, the harmless nature of 222 nm wavelength FUL allows researchers to better observe and record changes in algae under FUL irradiation.

[0019] This invention utilizes a triangular prism structure formed by a light-shielding cover and a quartz glass plate to enclose the ultraviolet lamp, thus securing and protecting it. Simultaneously, the enclosure protects the ultraviolet lamp, stirring components, and algae-carrying container, preventing collision damage and facilitating device movement. Furthermore, the enclosure effectively reduces interference from external factors (such as dust, moisture, and other microorganisms) on the algae-killing effect. Attached Figure Description

[0023] The present invention will now be described in detail with reference to the accompanying drawings.

[0024] like Figure 1 As shown, a far-ultraviolet (FUL) water purification device is used to conduct experiments testing the FUL algae-killing effect of FUL under different conditions. These conditions include one or more of temperature, ultraviolet light intensity, and stirring rate. In this embodiment, 222nm FUL ultraviolet light is used.

[0025] The far-ultraviolet light water purification device includes a housing 1, a stirring assembly, an algae-carrying container 4, an ultraviolet irradiation assembly, and a temperature control assembly. The ultraviolet irradiation assembly is installed inside the housing 1. The stirring assembly and the temperature control assembly are also installed inside the housing 1. The housing 1 is rectangular and has an opening on its side. A rotatable door is rotatably connected to one side of the opening. The opening is used for the user to insert or remove the algae-carrying container 4.

[0026] like Figure 2 As shown, the stirring assembly includes a magnetic stirrer 2 and a magnetic stirring rod 3. The magnetic stirrer 2 is fixed to the bottom of the inner cavity of the housing 1. The algae-carrying container 4 and the temperature control assembly are mounted on the magnetic stirrer 2. The magnetic stirring rod 3 is placed inside the algae-carrying container 4 and can rotate under the non-contact magnetic drive of the magnetic stirrer 2, thereby stirring the algae solution in the algae-carrying container 4. The stirring assembly is used to agitate the water flow, ensuring that the algae in the water receive light evenly.

[0027] The temperature control component is used to regulate the temperature of the algae solution in the algae-carrying container 4. In this embodiment, the temperature control component includes a thermostatic bath 5. The thermostatic bath 5 is a container with an opening at the top, which is placed on the magnetic stirrer 2. The algae-carrying container 4 is placed inside the thermostatic bath 5.

[0028] The constant temperature bath 5 is equipped with an inlet and an outlet. The inlet and outlet of the constant temperature bath 5 are connected to an external liquid medium supply device to form a circulation loop. By circulating a liquid medium at the target temperature into the constant temperature bath 5, the algae solution in the algae-carrying container 4 maintains the target temperature throughout the treatment process. By adjusting the temperature of the liquid medium input into the constant temperature bath 5, far-ultraviolet algae sterilization experiments under different temperature conditions can be conducted. In this embodiment, the liquid medium is condensate.

[0029] The ultraviolet irradiation assembly includes a light-shielding cover 6, an ultraviolet lamp 7, and a collimating tube 8. The light-shielding cover 6 is located at the top opening of the housing 1. The ultraviolet lamp 7 is installed inside the light-shielding cover 6. The collimating tube 8 is installed at the bottom of the light-shielding cover 6. The collimating tube 8 is located between the ultraviolet lamp 7 and the top opening of the algae-carrying container 4. The collimating tube 8 can improve the parallelism of the far-ultraviolet light irradiating the algae solution.

[0030] In some embodiments, the ultraviolet lamp 7 is a far-ultraviolet lamp tube with an emission wavelength of 222 nm.

[0031] In some non-essential embodiments, the bottom of the light-shielding cover 6 is provided with a quartz glass plate that allows far-ultraviolet light to pass through. The quartz glass plate is located between the ultraviolet lamp 7 and the collimator 8.

[0032] In some non-essential embodiments, a cylindrical limiting cavity is provided at the top of the inner cavity of the box 1. The collimating tube 8 is disposed in the cylindrical limiting cavity. The collimating tube 8 and the algae carrying container 4 are both cylindrical, with their axes coinciding and their radii being equal.

[0033] The working principle of this utility model is as follows:

[0034] First, open the switch door on the front of the cabinet 1 and inject condensate water at the target temperature into the thermostatic bath 5.

[0035] Next, place the algae carrier container 4 containing the algae to be treated into the constant temperature bath 5, and align the algae carrier container 4 with the collimation tube 8.

[0036] Then, place the magnetic stirring rod 3 into the algae carrier container 4, turn on the magnetic stirrer 2 to stir, so that the tank in the algae carrier container 4 is evenly exposed to light.

[0037] Finally, close the door of the box 1 and turn on the ultraviolet lamp 7 to kill the algae in the algae-carrying container 4.

[0038] In some embodiments, by adjusting the target temperature, ultraviolet light intensity, and stirring speed, and repeating the experimental process, the effects of different treatment conditions on the algae removal effect can be obtained, thereby achieving optimized design of the algae removal process.
