Abstract

The invention relates to a submarine low temperature plasma air sterilization purifier, comprising a plasma reactor, a pulse power supply, a fan assembly, a control device, an air inlet, an air outlet and a case; wherein the plasma reactor is internally provided with a positive electrode which is formed by the way that a plurality of nickel-chromium metal wires or nickel-chromium metal bands are arranged in the same plane in parallel at equal distance, the two ends of the positive electrode are fixed in corresponding grooves or convex parts on a conductor rail preventing micro discharge; the two sides of a negative electrode made by aluminium are provided with nano TiO2; and a pulse transformer is arranged in the pulse power supply, and the pulse transformer and a switching tube in a pulse generator are in single-end flyback inverter setting. The sterilization factor of the invention is free radical produced by the way that low temperature plasma is heated to excite TiO2. The invention can carry out complete sterilization and purification on harmful gas, nuclear pollution particle matter, volatile organic compound and bacterial virus in submarine. The invention has high efficiencyin removing nuclear radioactive aerosol and sterilizing and purifying air, good reliability, strong resistance and convenient mounting and use.

Description

Technical field: [0001] The invention belongs to the technical field of air disinfection and purification, and specifically relates to a submarine low-temperature plasma air disinfection and purification device. Background technique: [0002] Countries all over the world design submarines to improve combat effectiveness, and the combat effectiveness of submarines is the combination of all crew and weapons. As we all know, when a submarine goes out to dive at sea, it closes the elevator port and isolates it from the atmosphere. For combat, patrol or training needs, it is common to lie on the seabed for one or two months. In an environment where the temperature in the submarine cabin can reach 40℃ and the humidity is 85%, serious air pollution can be imagined: harmful gases, volatile organic compounds, and particulate matter caused by the submarine’s own manufacturing materials, equipment operation and the activities of hundreds of crew members. , Bacteria and viruses. For examp...
