Description

Technical Field

[0001] This utility model belongs to the field of organic pollutant treatment technology, and in particular relates to a photocatalytic device for treating chlorophenol organic pollutants. Background Technology

[0002] Chlorophenols are a class of organic compounds with chlorine atoms and hydroxyl groups attached to a benzene ring. Common examples include 2,4-dichlorophenol and pentachlorophenol. They are widely sourced, generated and emitted during processes such as chemical production, pesticide manufacturing, and wood preservation. Due to their high toxicity, recalcitrant nature, and bioaccumulation, chlorophenols can remain in water and soil for extended periods once they enter the environment. This not only severely damages aquatic organisms and soil microorganisms but can also threaten human health through the food chain, causing serious consequences such as carcinogenicity, teratogenicity, and mutagenicity. Therefore, effective treatment of chlorophenols is extremely important.

[0003] Chinese patent application CN221971317U discloses a photocatalytic degradation device, including a treatment tank and a cleaning mechanism. The cleaning mechanism, used to ensure degradation effectiveness, is located on both sides of the interior of the treatment tank. The cleaning mechanism includes a second motor, a threaded shaft, a connecting frame, a scraper, a cleaning ring, and an ultraviolet lamp. The output end of the second motor is connected to the threaded shaft, and the connecting frame is connected to the external thread of the threaded shaft. Compared with existing devices, this photocatalytic degradation device, through the cooperation of the various parts of the cleaning mechanism, can clean the outer surface of the ultraviolet lamp, thereby maintaining the radiation effect of the ultraviolet lamp during long-term photocatalytic degradation, thus ensuring high efficiency in degradation. Simultaneously, the scraper can also scrape and clean the outer surface of the treatment tank, thereby improving the convenience of the device and reducing manual handling.

[0004] In the actual process of treating chlorophenol organic pollutants, pH value affects the adsorption behavior of pollutants on the surface of photocatalysts, as well as the generation and stability of active substances. Different chlorophenol compounds have different degradation rates under different pH conditions. However, existing organic pollutant treatment devices cannot adjust the pH value when treating chlorophenol organic pollutants, which leads to a decrease in the decomposition rate.

[0005] To address these issues, we provide a photocatalytic chlorophenol organic pollutant treatment device. Utility Model Content

By quantitatively injecting pH-adjusting liquid from the storage tank into the treatment tank through the dispensing and injection pipes, the pH value of the liquid to be treated in the treatment tank is adjusted, thus solving the problem of low treatment rate in existing organic pollutant treatment devices.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is a photocatalytic chlorophenol organic pollutant treatment device, including a treatment tank; a top cover is fixed at the center of the top of the treatment tank, a stirring assembly is provided inside the treatment tank, a drug storage assembly is provided on the side of the treatment tank, a drug injection assembly is provided on the top of the drug storage assembly, and multiple catalyst storage assemblies and ultraviolet lamps are installed inside the treatment tank.

[0009] The drug storage assembly includes a mounting frame fixed to the outside of the processing tank, a drug storage tank placed inside the mounting frame, a drug outlet pipe with its top penetrating the drug storage tank fixed inside the drug storage tank, a first one-way valve fixed to the top of the drug outlet pipe, and a drug injection pipe connected between the output port of the first one-way valve and the processing tank.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see Figures 1 to 4 This utility model is a photocatalytic chlorophenol organic pollutant treatment device, including a treatment tank 100; a top cover 106 is fixed at the center of the top of the treatment tank 100, a stirring assembly 400 is provided inside the treatment tank 100, a drug storage assembly 200 is provided on the side of the treatment tank 100, a drug injection assembly 300 is provided on the top of the drug storage assembly 200, and multiple catalyst storage assemblies 500 and ultraviolet lamps 600 are installed inside the treatment tank 100.

[0032] The drug storage assembly 200 includes a mounting frame 201 fixed to the outside of the treatment tank 100. A drug storage tank 202 is placed inside the mounting frame 201. A drug outlet pipe 203 with its top penetrating through the drug storage tank 202 is fixed inside the drug storage tank 202. A first one-way valve 204 is fixed to the top of the drug outlet pipe 203.

A pH adjuster is injected into the interior of the treatment tank 100 through the drug injection pipe 205, which can adjust the pH value of the solution in the treatment tank 100, thereby improving the decomposition efficiency of chlorophenol organic pollutants.

[0033] The injection assembly 300 includes a second one-way valve 307 installed on the top of the storage tank 202. A three-way pipe 308 is installed at the inlet of the second one-way valve 307. An air pump 301 is installed at the top interface of the three-way pipe 308. A sliding frame 302 is fixedly installed on the outside of the air pump 301. A slider 305 is slidably connected to the outside of the sliding frame 302. A fixing screw 306 is threaded on the front of the slider 305 and abuts against the front of the sliding frame 302.

An n-shaped frame 304 is fixedly installed on the outside of the piston rod of the air pump 301, and the sliding ring 303 is fixed at the bottom of the n-shaped frame 304. By pulling the slider 305 and tightening the fixing screw 306, the slider 305 can be fixed, thereby limiting the upward movement distance of the sliding ring 303, thus realizing the adjustment of the injection volume of pH adjuster.

[0034] Specifically, a drain pipe 101 connected to the bottom of the treatment tank 100 is fixedly connected to the bottom of the treatment tank 100. A drain valve 102 is installed at the bottom of the drain pipe 101.

[0039] The exterior of the sliding frame 302 is engraved with evenly distributed scale lines.

[0040] The operation process of this embodiment is as follows: When it is necessary to decompose and treat chlorophenol organic pollutants, firstly, the slider 305 is pulled according to the type of chlorophenol organic pollutant, and then the fixing screw 306 is tightened, thereby adjusting the injection amount of pH adjuster. Then, the piston rod of the suction cylinder 301 is pulled upward, and then outside air enters the suction cylinder 301 through the suction pipe 309 and the third one-way valve 310. When the sliding ring 303 touches the slider 305, the piston rod of the suction cylinder 301 is pressed downward, thereby injecting the air in the suction cylinder 301 into the storage tank 202. Then, the pH adjusting liquid in the storage tank 202 is squeezed into the treatment tank 100 through the outlet pipe 203 and the injection pipe 205, thereby adjusting the pH value of the liquid to be treated in the treatment tank 100 and increasing the decomposition rate of chlorophenol organic pollutants. Then, the catalyst stored in the storage tank 501 can decompose chlorophenol organic pollutants under the irradiation of the ultraviolet lamp 600.

[0043] The operation process of this embodiment is as follows: During the decomposition of chlorophenol organic pollutants, the stirring motor 402 is started to drive the stirring shaft 401 to rotate, thereby stirring the liquid in the treatment tank 100, so that the chlorophenol organic pollutants can fully contact the catalyst stored in the storage tank 501, and further improve the decomposition rate of chlorophenol organic pollutants.
