Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to a photocatalytic wastewater treatment device. Background Technology

[0002] Photocatalytic reactors primarily utilize photocatalysts to degrade organic matter. A photocatalyst is a substance with photocatalytic activity that, under the influence of light energy, oxidizes organic matter into inorganic substances while simultaneously being reduced to an ionic state. In a photocatalytic reactor, the photocatalyst is suspended and dispersed in water. When wastewater passes through the reactor, the organic matter is oxidized and degraded by the photocatalyst. To improve reaction efficiency, photocatalytic reactors, such as those described in patent 202221263583.3, all have a separate stirrer installed inside the reactor, and the ultraviolet lamp is fixedly installed inside. As the photocatalytic reaction proceeds, dirt accumulates on the outer surface of the ultraviolet lamp, making cleaning inconvenient. Summary of the Invention

[0003] The main objective of this invention is to provide a photocatalytic wastewater treatment device, which aims to at least solve one of the technical problems existing in the background art.

[0004] Therefore, the photocatalytic wastewater treatment equipment provided by this utility model includes a photocatalytic reactor with an open top. A support beam is provided above the top of the photocatalytic reactor. A horizontal turntable and a motor for driving the horizontal turntable to rotate are provided on the support beam. A plurality of recessed holes for suspending and installing ultraviolet lamps are evenly distributed on the horizontal turntable. A hook is provided at the upper end of the ultraviolet lamp. The ultraviolet lamp is inserted into the photocatalytic reactor after passing through the recessed hole. The hook is locked in the large diameter end of the recessed hole.

[0005] Specifically, the ultraviolet lamp is designed in the form of a sheet.

[0006] Specifically, the bottom of the photocatalytic reactor is equipped with an aeration disc.

[0007] Specifically, the photocatalytic reactor has an inlet at the bottom and an outlet on the upper side, with a filter screen on the outlet.

[0008] Specifically, the photocatalytic reactor is filled with particulate photocatalyst.

[0009] Compared with the prior art, the present invention has the following advantages: the ultraviolet lamp is suspended on a horizontal turntable. When the horizontal turntable rotates, the ultraviolet lamp acts as a stirring rod, eliminating the need for a separate stirrer. Moreover, when the ultraviolet lamp needs to be cleaned, it can be simply pulled out of the horizontal turntable. The installation and removal of the ultraviolet lamp is very convenient.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0016] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0017] See Figure 1and Figure 2 A photocatalytic wastewater treatment device includes a photocatalytic reactor 1 with an open top, an inlet 2 at the bottom, an outlet 3 on the upper side, a granular photocatalyst 4 inside the photocatalytic reactor 1, a support beam 5 on the top of the photocatalytic reactor 1, a horizontal turntable 6 and a motor 7 for driving the horizontal turntable 6 to rotate on the support beam 5, a plurality of recessed holes 9 evenly distributed on the horizontal turntable 6 for suspending and installing ultraviolet lamps 8, a hook 10 on the upper end of the ultraviolet lamp 8, the ultraviolet lamp 8 is inserted into the photocatalytic reactor 1 after passing through the recessed hole 9, and the hook 10 is locked in the large diameter end of the recessed hole 9.

[0018] The above-mentioned photocatalytic wastewater treatment equipment operates as follows: wastewater enters the photocatalytic reactor 1 through inlet 2. Ultraviolet lamp 8 is activated to generate ultraviolet light, while motor 7 drives the horizontal turntable 6 to rotate slowly. Ultraviolet lamp 8 acts as a stirring rod, ensuring the catalyst is evenly distributed within the photocatalytic reactor 1. In the presence of the catalyst, the wastewater undergoes a photocatalytic reaction under ultraviolet irradiation, achieving wastewater purification. The treated wastewater flows out through outlet 3. During the rotation of the horizontal turntable 6, ultraviolet lamp 8 remains stable due to its own gravity. The granular photocatalyst 4 refers to a photocatalytic material existing in particulate form, possessing a large specific surface area and good dispersibility, and is widely used in photocatalytic reactions. Examples include titanium dioxide and zinc oxide.

[0019] In this embodiment, the ultraviolet lamp 8 is suspended on the horizontal turntable 6. When the horizontal turntable 6 rotates, the ultraviolet lamp 8 directly acts as a stirring rod, eliminating the need for a separate stirrer. Moreover, when it is necessary to clean the ultraviolet lamp 8, it is only necessary to pull the ultraviolet lamp 8 out of the horizontal turntable 6. The installation and removal of the ultraviolet lamp 8 are very convenient.

[0020] Understandably, to improve the stirring effect, the UV lamp 8 is designed as a flat sheet, and to prevent the catalyst from leaking out of the outlet 3, an intercepting filter 12 is installed on the outlet 3. Four, five, or even more sinkholes 9 can be set along the circumference of the horizontal turntable 6.

[0021] See Figure 1 In some embodiments, an aeration disc 11 can be added to the bottom of the photocatalytic reactor 1. The aeration disc 11 aerates the photocatalytic reactor 1, increases the oxygen supply, promotes mixing and mass transfer, increases the reaction rate, and prevents catalyst precipitation, thereby significantly improving the efficiency and effect of the photocatalytic reaction.

[0022] Unless otherwise stated, if any of the technical solutions disclosed in this utility model discloses a numerical range, then the disclosed numerical range is a preferred numerical range. Anyone skilled in the art should understand that the preferred numerical range is merely one among many feasible numerical values ​​that has a more obvious or representative technical effect. Because there are many numerical values, it is impossible to list them all. Therefore, this utility model discloses only some numerical values ​​to illustrate the technical solutions of the invention. Furthermore, the numerical values ​​listed above should not constitute a limitation on the scope of protection of this invention.

[0023] Meanwhile, if the present invention discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured by casting) (except where it is obviously impossible to use an integral forming process).

[0024] Furthermore, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model include states or shapes that are similar to, analogous to, or close to those states or shapes. Any component provided by this utility model can be assembled from multiple individual components or can be a single component manufactured using a one-piece molding process.
