Technical Field

[0001] This utility model relates to the field of wastewater treatment technology in fine chemical industry, and in particular to a tray-type photocatalytic reactor. Background Technology

[0002] Photocatalytic reactors are one of the mainstream equipment for wastewater treatment. They mainly utilize photocatalysts inside the reactor to effectively decompose organic matter in wastewater as it passes through the carrier under the action of light. They are suitable for the treatment of chemical wastewater.

[0003] Photocatalytic reactors require continuous light source irradiation during use. In normal use, sunlight is generally used for irradiation, supplemented by artificial light. After long-term use, impurities tend to accumulate on the surface of the photocatalytic reactor, affecting the contact between light and photocatalyst, which has certain defects.

[0004] Therefore, a tray-type photocatalytic reactor is provided to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background art and to propose a tray-type photocatalytic reactor.

[0012] Preferably, an mounting ring is fixedly connected to the inner ring of the inflatable airbag, and the inflatable airbag is fixedly connected to the mounting ring.

[0013] To facilitate cleaning, preferably, a rotating ring is rotatably connected to the mounting ring, and multiple sets of brush bristles that are in contact with the photocatalytic reactor body are fixedly connected to the rotating ring.

[0014] To facilitate the rotation of the bristles, preferably, the rotating ring is provided with multiple sets of inclined blades, and the inflatable airbag is provided with multiple sets of air holes II, with the air holes II facing the blades.

[0018] Compared with the prior art, this utility model provides a tray-type photocatalytic reactor, which has the following beneficial effects:

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1:

[0029] Reference Figure 1-6 A tray-type photocatalytic reactor includes a reaction tower 1, a photocatalytic reactor body 2 fixedly connected inside the reaction tower 1, and further includes: an inflatable bladder 4 slidably connected inside the reaction tower 1; a first connecting pipe 401 connected to the inflatable bladder 4, the first connecting pipe 401 being used to inflate the inflatable bladder 4; an expansion bladder 5 sleeved on the photocatalytic reactor body 2, the expansion bladder 5 having multiple sets of first vents 501 facing the photocatalytic reactor body 2; a second connecting pipe 402 connected to the inflatable bladder 4, the second connecting pipe 402 having a one-way valve, the second connecting pipe 402 being connected to the expansion bladder 5, an mounting ring 3 fixedly connected to the inner ring of the inflatable bladder 4, the expansion bladder 5 being fixedly connected to the mounting ring 3, and the first connecting pipe 401 being a telescopic flexible hose.

[0030] When using this device, an air pump is required for assistance. Under normal conditions, the reaction tower 1 should be filled with liquid, and the photocatalytic reactor body 2 is also immersed in water. Water is forced into the photocatalytic reactor body 2 by water pressure and then discharged through the liquid outlet of the photocatalytic reactor body 2. The liquid outlet of the photocatalytic reactor body 2 is equipped with a pipeline connected to the outside and does not directly discharge into the reaction tower 1.

[0031] In actual use, gas is continuously injected into the connecting pipe 401 by an air pump. This gas injection causes the inflation bladder 4 to expand. Some of the gas inside the inflation bladder 4 will enter the expansion bladder 5 through the connecting pipe 402, causing the expansion bladder 5 to expand and cover the surface of the photocatalytic reactor body 2. Since the mounting ring 3 has a certain weight, as the gas is continuously injected, when the intake volume is greater than the output volume, the inflation bladder 4 will expand accordingly, causing the mounting ring 3 to move upward continuously. Through this upward movement, the expansion bladder 5 scrapes and cleans the surface of the photocatalytic reactor body 2. At the same time, some gas will be discharged through the vent 501, which plays an auxiliary cleaning role.

[0032] Subsequently, when the air intake is less than the air output, the entire installation ring 3 will continue to move downwards.

[0033] By moving up and down in this way, the surface of the photocatalytic reactor body 2 can be continuously cleaned, which facilitates the long-term use of the photocatalytic reactor body 2.

[0034] Example 2:

[0035] Reference Figure 1-6 A tray-type photocatalytic reactor is basically the same as in Example 1, but with the following additional features: a rotating ring 7 is rotatably connected to the mounting ring 3; multiple sets of brush bristles 8 are fixedly connected to the rotating ring 7 and are attached to the photocatalytic reactor body 2; multiple sets of inclined blades 9 are provided on the rotating ring 7; multiple sets of vent holes 502 are provided on the expansion bladder 5, with the vent holes 502 facing the blades 9; a sliding groove 6 is fixedly connected to the mounting ring 3; the rotating ring 7 is slidably connected to the sliding groove 6; a mounting frame 201 is fixedly connected to the reaction tower 1; and the photocatalytic reactor body 2 is mounted on the mounting frame 201.

[0036] During use, the second vent 502 will continuously discharge gas. This gas will impact the blade 9, causing the rotating ring 7 to rotate. This allows the bristles 8 to clean the surface of the photocatalytic reactor body 2. The rotation of the bristles 8 will continuously and effectively clean the surface of the photocatalytic reactor body 2, reducing the possibility of impurities being trapped in the gaps of the bristles 8 and unable to be discharged.

[0037] After a period of use, the brush bristles 8 need to be replaced to reduce the situation where the brush bristles 8 are worn out and cannot make contact with the surface of the photocatalytic reactor body 2.

[0038] This invention uses air to inflate the airbag 4, which causes the expansion airbag 5 to move up and down. The expansion airbag 5 continuously cleans the surface of the photocatalytic reactor body 2, reducing the adhesion of scale and other dirt to the surface of the photocatalytic reactor body 2, thus facilitating the long-term use of the photocatalytic reactor.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
