Problems solved by technology

In view of the fact that the turn-on and turn-off times of semiconductor power switching devices are at the uS level, it is difficult to meet the above two conditions with conventional design methods
nS-level high-voltage high-power switching devices are expensive and have a short working life, so it is impractical to design them in civilian products

Abstract

The invention belongs to the technical field of clean rooms, in particular relates to a clean room with a non-thermal plasmas air disinfection purifier. The clean room comprises an air purification unit, a reactor power, a fan, the clean room, a fresh air system, a controller, an air return trench, an air filter, a static pressure box, a return air pipe and a grating floor. The air purification unit is installed in the static pressure box arranged above the clean room to form an airtight environment; the air purification unit is a plasma reactor, is internally provided with a plurality of nickel-chromium metal wires or metal bands which are arranged in parallel according to equal distance in the same plane to prepare a positive electrode, two ends of the air purification unit are fixed in a corresponding groove or convex part on a conductive rail for preventing micro-discharge, and a switch tube in the reactor power is arranged by a single-end flyback inverter. The invention provides the clean room, which has the advantages of comprehensive air purification and disinfection effect, high efficiency, low energy consumption, low noise, simple structure, maintenance cost saving and long service life and can be applied to an industrial or biological clean room.

Description

Technical field: [0001] The invention belongs to the technical field of air disinfection and purification, and in particular relates to a clean room equipped with a non-thermal plasma air disinfection purifier. Background technique: [0002] A clean room is designed to reduce the dust particles, toxic and harmful gases, and bacterial virus pollutants in the indoor air to below the specified indicators, and to design the indoor temperature and humidity, static electricity control, electromagnetic interference, noise, and lighting according to requirements. Room. In November 2001, my country released the latest "Code for Design of Clean Workshops" (GB50073-2001), which newly defined five clean rooms from Class 5 to Class 1. The existing clean room mainly includes a clean space, a fan filter unit and a combined purification air conditioner. When working, the air regulated by the combined purification air conditioner enters the negative pressure space above the fan filter unit...
