Embodiment 1

[0052] figure 1 It is a structural schematic diagram of an air disinfection purifier with optimal combination of plasma and titanium dioxide in the present invention; figure 2 It is the front view of the plasma reactor of the present invention.

[0053] Such as figure 1 As shown, the air disinfection purifier with optimal combination of plasma and titanium dioxide includes a plasma reactor 1, a pulse power supply 2, a fan assembly 3, an air inlet 5, an air outlet 6 and a casing 8. The air inlet 5 is provided with a primary effect air filter 401 and a medium effect air filter 402 , and the air outlet 6 is provided with a primary effect air filter 401 . The plasma reactor 1 and the fan assembly 3 are arranged in the air flow, and the plasma reactor 1 is provided with positive electrodes 101 made of several nickel-chromium metal wires or nickel-chromium metal strips arranged in parallel at equal distances in the same plane, The positive electrode 101 is placed in the middle o...

Embodiment 2

[0063] image 3 It is a working schematic diagram of the air disinfection purifier of the present invention. A titanium dioxide catalytic plate 403 can also be provided between the plasma reactor 1 and the fan assembly 3, the titanium dioxide catalytic plate 403 is made of a surface alumina plate, and the aluminum plate is provided with evenly densely distributed small round holes as air flow channels, and the aluminum plate is close to Nano TiO is laid on the plane of the plasma reactor 1 2 . The nanoscale TiO 2 It is an anatase catalyst with a band gap energy of 3.2eV. The anatase catalyst has a high band gap energy, which can kill viruses and bacteria, and degrade TVO S The effect is good.

Embodiment 3

[0065] The fan assembly 3 of the present invention is provided with a low-noise fan with serrated edge fan blades, the height of the teeth is 4-8mm, and the distance between the teeth is 5-10mm, and the height of the teeth and the distance between the teeth are designed according to the speed of the fan . According to the bionics point of view, the feathers on the edge of the bird's wings are serrated, and the friction noise between the up and down fluctuation of the wings and the high-speed airflow is extremely low. Compared with the ordinary fan with the same power and air volume, the low-noise fan with serrated edge blades has an average noise index 3-5dB lower. An ordinary fan has an outer diameter of 220mm, a duct length of 60mm, a voltage of 220V / 50Hz, a working current of 0.60A, and an air volume of 1200m 3 The noise at / h is 59.5dB(A), and the measured noise is 54.8dB(A) after replacing the fan blades with serrated edges of the same size.

The air disinfection purifier by the optimized combination of plasma and titanium dioxide comprises a plasma reactor, a pulse power supply, a blower assembly, an air inlet, an air outlet and an outer shell, wherein the air inlet and the air outlet are respectively provided with an air filter, the plasma reactor is internally provided with a positive electrode formed by equidistantly arranging a plurality of nickel-chromium metal wires or nickel-chromium metal bands in parallel on the same plane, both ends of the positive electrode are fixed in corresponding grooves or protrusions on a conductor rail resisting micro-discharge, both sides of a negative electrode are coated with nano-level TiO2, the pulse power supply is internally provided with an EMC (Electromagnetic Compatibility) filter, a rectifier circuit, a filter circuit, a pulse generator and a pulse transformer, and switching tubes in the pulse transformer and the pulse generator are set by a single-ended flyback inverter. The optimized combination of the plasma and the titanium dioxide realizes advantage complementation and win-win combination, and the invention has the advantages of high air disinfection and purification efficiency, energy saving, good reliability, long service life, simple structure and low cost.

Description

Technical field: [0001] The invention belongs to the technical field of air disinfection and purification, and in particular relates to an air disinfection purifier with optimal combination of plasma and titanium dioxide. Background technique: [0002] With the advancement of human civilization, the earth's ecological environment on which human beings depend is deteriorating, and air pollution is becoming more and more serious: bacteria such as Legionella, Staphylococcus and Mycoplasma and their various viruses; various types of volatile organic Compound VOC S ; Particulate pollution such as dust particles and radioactive particles in the form of aerosols. It is particularly emphasized that in recent years, large-scale outbreaks of SARS, bird flu and various influenza viruses have occurred from time to time. In particular, the current H1N1 flu has infected more than 300,000 people worldwide and killed nearly 3,000 people. The infection route of Influenza A (H1N1) is mainl...
