Description

Technical Field

[0001] The invention belongs to the technical field of air purification, and relates to a high-efficiency and high-energy oxygen and photosynthetic catalytic deodorization and disinfection air purification device. Background Art

[0002] Some existing odor removal technologies will produce secondary pollution during the application process (such as combustion method, absorption method), and some will consume materials such as catalysts, adsorbents, and chemicals during the application process (such as chemical method, adsorption method, biological method, neutralization method, photocatalyst method, etc.). All of them need to regularly replace activated carbon, catalysts and other raw materials, resulting in high treatment costs and the generation of solid waste. From another aspect, it adds pollution sources to environmental protection and increases the difficulty of environmental protection. Summary of the invention

[0003] In order to solve the technical problems existing in the above-mentioned background technology, the present invention provides a high-efficiency and high-energy oxygen and photosynthetic catalytic deodorization and disinfection air purification device, comprising: a lower open draft hood, a lower porous insulating fixing plate, a quartz glass tube, an upper porous insulating fixing plate, an axial flow induced draft fan and a purified air outlet are sequentially installed from bottom to top; a dielectric barrier discharge multilayer ozone generating tube and a pulse ionization activated reduction catalyst carrier block layer are arranged from bottom to top in the quartz glass tube; high-frequency pulse dischargers and sinusoidal high-voltage ozone dischargers are installed on both sides of the axial flow induced draft fan; The axial flow induced draft fan sucks the odorous gas through the lower open induced draft hood and evenly distributes it to each quartz glass tube. The lower end of the quartz glass tube is provided with a dielectric barrier discharge multilayer ozone generating tube, which is connected to a sine wave high-voltage ozone discharger to suck the odorous gas containing oxygen ( ) ionizes into high-energy reactive oxygen species ( ), since high-energy active oxygen is a strong oxidant, after its formation, it will strongly oxidize and decompose the odor sources in the coexisting odorous gas: organic matter, hydrogen sulfide, ammonia, CO and other components, and react and reduce carbon substances.

[0004] Furthermore, a pulse ionization activation reduction catalyst carrier block layer is provided at the upper end and is connected to a high-frequency pulse discharger. The high-frequency pulse discharger performs work discharge to activate the multi-layer rare earth element catalyst carrier block to decompose and reduce O3 into O2. At the same time, components such as CO and NO are ionized and decomposed in the pulse discharge environment. Under the condition of catalyst activation, O and O are reduced, and N and N are reduced.

[0005] Furthermore, the dielectric barrier discharge multilayer ozone generating tube and the sinusoidal high-voltage ozone discharger are used to ionize and activate the oxygen in the odorous gas. It forms a strong oxidant, oxidizes the odor source components in the gas, such as organic, hydrogen sulfide, ammonia, CO, etc., and separates carbon from oxygen and reduces them separately.

[0006] Furthermore, the organic matter that has not been cleaned up is adsorbed on the carrier block by nuclear electricity through ionized plasma, and further high-energy gas oxidation is carried out, while the unreduced organic matter is The pyrolysis process is completed by reducing the ions to the required level, achieving a purification efficiency of 70 to 95%.

[0007] Furthermore, the pulse ionization activated reduction catalyst carrier block layer is an irregular porous ceramic sheet sprayed with rare earth elements and transition metal elements to form a catalyst carrier, which is composed of multiple layers of N blocks stacked together. Due to its non-irregular structure, it can form a natural chaotic field, which can better extend the travel distance of the treated exhaust gas and increase the treatment efficiency.

[0008] Furthermore, the lower porous insulating fixing plate and the upper porous insulating fixing plate are used to fix the quartz glass tube and play an insulating and safety role.

[0009] Furthermore, a purified air outlet is provided on the top of the axial flow induced draft fan to output and discharge the purified gas that meets the standards in a directional manner.

[0010] The beneficial effects of the present invention are: The present invention provides a high-efficiency and high-energy oxygen-photosynthetic catalytic deodorization and sterilization air purification device, which adopts the principle of strong sterilization and oxidation of gases containing bacteria, formaldehyde gas and foul odors produced during the oxidation and corruption of organic matter, and is equipped with an "extended surface discharge" ozone generation zone system device. At the same time, high-frequency pulse plasma is used to ionize and crack the gas containing oily microparticles, degrade it, and attach nuclear electrons to change the chain valence chain of the treated gas. At the same time, a porous sponge catalyst carrier block synthesized by rare earth elements and transition metal catalysts with thermocompression electrical release to increase discharge energy is provided to reduce the organic odor sources and oxides attached to the nuclear electrons after ionization and cracking and degradation, and ionize and catalytically reduce the ozone O3 with strong oxidation function. At the same time, it enters the ultraviolet light ozone reduction system to reduce the ozone that has not been fully reduced, and strongly oxidizes and kills or degrades, cracks and reduces the odorous and smelly gases and harmful substances such as formaldehyde and bacteria. It is used for purification and deodorization of odorous gases generated in sewage treatment plants, cold storage rooms, garbage rooms or warehouses, crematoriums, farms and other places. Through adjustment, the purification efficiency can reach 70-95%.
