Description

Technical Field

[0001] The present invention relates to an oxidative degradation device, in particular to an organic pollutant catalytic oxidative degradation device, belonging to the technical field of organic pollutant treatment. Background Art

[0002] With the acceleration of industrialization and urbanization, organic pollutants, a major type of environmental contaminant, are widely present in media such as water, atmosphere, and soil. Pollutants, represented by natural organic substances such as carbohydrates, proteins, amino acids, and fats, as well as numerous synthetic organic compounds, not only disrupt ecosystem balance, leading to problems such as eutrophication of water bodies and degradation of soil functions, but also some of their components can be transmitted through the food chain, causing serious harm to human health, such as carcinogenicity, teratogenicity, and mutagenicity. According to the World Health Organization, global ecological and environmental losses caused by organic pollution amount to hundreds of billions of dollars annually. Effectively controlling organic pollutants has become a key issue in environmental protection.

[0003] At present, pollutant catalytic oxidation degradation equipment has significantly improved the degradation efficiency of organic pollutants by adding catalysts or regulating the reaction environment, and has been widely used in industrial wastewater treatment, waste gas purification and other fields. However, this technology still has major defects: during the catalytic oxidation degradation process, small molecule alcohols, acids, esters and other economically valuable by-products produced by the decomposition of organic pollutants are often directly discharged to the outside world along with high-temperature evaporation gases. For example, in chemical wastewater treatment scenarios, about 30%-40% of potentially recyclable beneficial substances are lost due to the lack of effective collection devices. This not only causes waste of resources and increases corporate production costs, but the escaped volatile substances may also cause secondary pollution. Existing equipment generally lacks an efficient collection system for beneficial by-products, making it difficult to achieve the synergistic benefits of pollutant control and resource recovery. There is an urgent need to develop new equipment with integrated pollutant degradation and by-product recovery functions. Summary of the Invention

[0004] The purpose of the present invention is to provide a catalytic oxidation degradation device for organic pollutants in order to solve the above problems, which has the effect of liquefying, collecting and treating some substances.

The positioning support ring is directly below the conical drainage frame, and the interior of the positioning support ring is slidably connected with a material storage collection tube.

[0012] Furthermore, in order to improve the convenience of material collection, a square connecting pipe is fixedly welded to the lower end of the output connecting pipe, and a connecting clamping pipe is provided at the other end of the square connecting pipe.

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-6As shown, a catalytic oxidation degradation device for organic pollutants includes a degradation protection outer box 1, which serves as the main frame and protective structure of the entire device, provides installation space for internal components, and plays a protective role at the same time, preventing the external environment from interfering with the internal processing process of the device, and also preventing harmful substances that may be generated inside the device from leaking to the outside world. A transparent isolation frame 2 is fixedly installed inside the degradation protection outer box 1, which plays an isolation role and divides the internal space of the degradation protection outer box 1 to a certain extent. A precipitation separation frame 3 is clamped on the upper end of the degradation protection outer box 1, which is a key component for separating and collecting precipitated products. A liquefaction drainage structure 4 is fixedly installed inside the precipitation separation frame 3. The function is to liquefy the precipitation products produced during the catalytic oxidation degradation of organic pollutants. The lower side of the precipitation separation frame 3 is slidably connected with a separation storage structure 5 for collecting the precipitation products treated by the liquefaction drainage structure 4. The upper end of the precipitation separation frame 3 is equipped with an output connecting pipe 6. The inner surface of the degradation protection outer box 1 is evenly provided with catalytic light sources 7 to provide a specific wavelength of light conditions for the catalytic oxidation degradation reaction of organic pollutants. The inner side of the degradation protection outer box 1 is evenly installed with catalytic electric heating tubes 8 to control the temperature inside the equipment. The interior of the degradation protection outer box 1 is fixedly installed with a spiral feed pipe 9 to evenly transport the catalytic raw materials to the inside of the device.

[0030] The degradation protection outer box 1 includes a basic outer frame, a functional funnel, and an output funnel. The basic outer frame is located in the center of the device and is the main support structure of the entire degradation protection outer box 1. The functional funnel is fixedly installed at the upper end of the basic outer frame, and the output funnel is welded to the lower end of the basic outer frame. It is used to collect and guide the products after catalytic oxidation degradation. The output end of the output funnel is removably installed with an output sealing plate, which serves to seal and control the output of the products. The lower end of the transparent isolation frame 2 is tightly fixed to the output funnel, and the upper end of the transparent isolation frame 2 is sealed to the inside of the functional funnel. The lower end of the spiral feed pipe 9 extends through the output funnel to the outside world, and the lower end of the spiral feed pipe 9 is fixedly connected to the output funnel. The spiral feed pipe 9 is evenly provided with output mounting holes, and an output one-way valve is installed inside the output mounting hole. Its main function is to transport catalyst or oxygen during the operation of the equipment to improve the catalytic oxidation effect. The spiral feed pipe 9 spirally extends upward from the side connected to the output funnel.

[0031] A fixed card frame is provided at the lower end of the precipitation separation frame 3, and the fixed card frame and the upper end of the degradation protection outer box 1 are slidably engaged with each other. The fixed card frame also plays the role of connecting the precipitation separation frame 3 with other components inside the degradation protection outer box 1. A connecting card slot is provided at the upper end of the precipitation separation frame 3, and the fixed card frame can be slidably engaged with the connecting card slot and cooperate with the fixed card frame to realize the modular connection of the precipitation separation frame 3 itself.

[0032] The liquefaction drainage structure 4 includes a liquefaction cooling network 401 and a conical drainage frame 402. The liquefaction cooling network 401 is fixedly installed inside the precipitation separation frame 3. During the catalytic oxidation degradation process of organic pollutants, some gaseous precipitation products such as water vapor, volatile organic compounds, etc. will be produced. The liquefaction cooling network 401 reduces the temperature of these gaseous products to below the dew point, thereby causing liquefaction and converting the gaseous products into liquid, which is convenient for subsequent separation and collection. Its mesh structure can make the gaseous products pass through evenly, increase the contact area between the gaseous products and the cooling surface, improve the liquefaction efficiency, ensure that the precipitated products can be fully liquefied, and reduce the residual unliquefied gaseous products. The conical drainage frame 402 is evenly and fixedly installed on the lower surface of the liquefaction cooling network. Its main function is to gather the liquefied products on the liquefaction cooling network 401 and guide them to the separation storage structure 5 below. The conical design enables the liquid product to flow naturally along the conical surface under the action of its own gravity and concentrate at the bottom of the conical drainage frame 402, thereby preventing the liquid product from splashing or remaining in the precipitation separation frame 3; the conical drainage frame 402 can also play a certain role in preventing backflow, thereby preventing the liquid product in the separation storage structure 5 below from flowing back to the liquefaction cooling network 401 area due to pressure changes and the like, thereby affecting the normal progress of the liquefaction process. The separation storage structure 5 includes a replacement installation frame 501, and a positioning slot is provided on one side of the precipitation separation frame 3. The replacement installation frame 501 is slidably connected to the inside of the positioning slot. The replacement installation frame 501 is slidably connected to the inside of the positioning slot. This design makes it easy to install and disassemble the replacement installation frame 501. When the storage collection pipe 503 in the separation storage structure 5 is full of precipitated products, the operator can quickly pull out the replacement installation frame 501 from the positioning slot, replace it with a new replacement installation frame 501, and continue to collect the precipitated products. The operation greatly improves the operating efficiency and maintenance convenience of the equipment. A pull-out operation groove is provided on the outside of the replacement installation frame 501, and a support card net 502 is fixedly installed inside the replacement installation frame 501. It is fixedly installed inside the replacement installation frame 501 to provide support for the positioning support ring, ensuring that the positioning support ring is in a stable position, thereby ensuring that the storage collection pipe 503 can be accurately located directly below the conical drainage frame 402 to receive the liquid precipitated product flowing down from the conical drainage frame 402. Through the fixing effect of the positioning support ring, it is ensured that the storage collection pipe 503 can accurately receive the liquid precipitated product flowing down from the conical drainage frame 402 to avoid spillage or incomplete collection of the liquid product. Positioning support rings are evenly arranged on the inside of the support card net 502, and the positioning support ring is located directly below the conical drainage frame 402. The storage collection pipe 503 is slidably connected to the inside of the positioning support ring to collect the liquid precipitated product flowing down from the conical drainage frame 402 for subsequent processing and disposal.

[0033] There is one, or at least two, precipitation separation frames 3. At least two precipitation separation frames 3 are stacked vertically between the output connecting pipe 6 and the degradation protection outer box 1 to achieve multi-layer condensation.

[0034] A square connecting tube 601 is fixedly welded to the lower end of the output connecting tube 6, and a connecting clamping tube is provided at the other end of the square connecting tube 601. The connecting clamping tube and the connecting clamping groove are slidably clamped with each other. The main function is to guide the liquid or gaseous precipitation products after liquefaction drainage, separation storage and other links in the precipitation separation frame 3 out of the inside of the precipitation separation frame 3. It is a key channel connecting the inside of the precipitation separation frame 3 with subsequent processing equipment or collection devices, ensuring that the precipitation products can leave the precipitation separation frame 3 smoothly and stably.

[0035] The upper end of the degradation-protective outer box 1 is longitudinally connected to the precipitation separation frame 3, which is then longitudinally connected to the output connection pipe 6. The connections between the degradation-protective outer box 1, the output connection pipe 6, and the precipitation separation frame 3 are all provided with a sealed connection structure. The lower side of the precipitation separation frame 3 has an insertion opening for a transversely sliding separation storage structure 5, with a sealing ring positioned between the separation storage structure 5 and the insertion opening to facilitate sealing. The sealing connection structure can be either a sealant or a sealing ring.

[0036] The following is the catalytic oxidation method of the degradation equipment of this application:

[0037] First, check that all components are securely installed, turn on the catalytic light source 7 and catalytic electric heating tube 8, set the illumination wavelength and temperature, and deliver the organic pollutant raw material into the transparent isolation frame 2 through the spiral feed pipe 9. The raw material decomposes under the synergistic effect of light and heat to produce small molecular products such as CO2 or H2O and gaseous recyclable by-products such as alcohol and acid. The liquid residue accumulates in the output funnel. When the liquid residue needs to be discharged, open the output sealing plate and discharge it through the output funnel. The gaseous product rises to the precipitation separation frame 3;

[0038] Then, the gaseous product is liquefied through the liquefaction cooling network 401 and introduced into the storage collection pipe 503 through the conical drainage frame 402. When the storage collection pipe is full, the replacement installation frame 501 is pulled out to replace the new storage collection pipe for continuous recycling.

[0039] Finally, the unliquefied gas is discharged through the output connecting pipe 6 and connected to the tail gas treatment system.
