Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] A kind of target breaks down low-temperature plasma air purification method, comprises the steps: A, the air that contains microorganism and harmful gas is introduced in the area that has microwave and low-temperature plasma environment;

[0024] B. Using one or more specific frequency microwave fields to resonate separately or simultaneously the C-C bonds, C-H bonds and N-H bonds in the microorganisms and harmful gas molecules in the air stream;

[0025] C. Use the high-energy particles generated by the low-temperature plasma generator to hit the microorganisms and harmful gases in the air flow, so that the C-C bonds, C-H bonds, and N-H bonds that resonate in the microorganisms and harmful gas molecules are broken.

[0026] Such as figure 1 , 2 As shown, the target-cut low-temperature plasma air purification device for reali...

Abstract

The invention discloses an air purifying method for target-direction breaking low-temperature plasma, which uses microwave to resonate the microorganism in the air with the bond C-C, the bond C-H and the bond N-H in the molecule of the harmful gas respectively or simultaneously, and then uses the high-energy particles generated by a low-temperature plasma generator to break off the molecular bonds. The device includes a dielectric cavity provided with an air inlet and an air outlet, a microwave generator and a low-temperature plasma generator are arranged in the cavity; a microwave shielding screen is arranged on the inner wall of the cavity; the low-temperature plasma generator consists of insulators, corona lines and copper plates; a plurality of corona lines are arrayed in the cavity, the corona lines and the cavity are fixed together through the insulators; the discharge electrodes of the corona lines are connected with the cathode of a high-voltage direct current pulse power supply, the two pieces of copper plates are respectively connected with the anode of the high-voltage direct current pulse power supply and the ground. The device can effectively kill microorganisms and pyrolyze the harmful gases, can solve the problem that killing microorganism in a flowing ir by microwave needs longer time, and has the advantages that the structure is novel and simple, and the cost is lower.

Description

technical field [0001] The invention relates to a method for disinfecting and purifying air and a device thereof, in particular to a method for purifying air by targeting and interrupting low-temperature plasma. Background technique [0002] With the continuous improvement of people's living standards, improving the air quality in public places such as homes, hotels, hospitals and offices, especially purifying the air in air-conditioned rooms is a long-term exploration of technical personnel in the field. The method of indoor air purification is not only to replace fresh air, but also to kill viruses and bacteria in the air and remove harmful gases. For example, the Chinese patent number is 03221917.2, and the invention name is "indoor air disinfection, sterilization and purification device" and the Chinese patent number is 200610095118.2, and the invention name is "tuyere type air disinfection purifier", etc. A method and device for disinfecting and purifying the air, such...
