Abstract

The invention relates to an air duct type electronic air purification machine, belonging to the field of air sterilization and purification technologies. The air purification machine comprises a plasma reactor, a pulse power source, an air inlet and an air outlet. A positive electrode and a negative electrode are arranged in the plasma reactor, wherein the positive electrode is made of an oxidation resisting metal strap, the negative electrode is made of an aluminum plate or a stainless steel plate, and both faces of the negative electrode are coated with TiO2. A micro discharge preventing conductor rail made of an aluminum bar or a stainless steel bar is also arranged, and both ends of the positive electrode are fixed on relative positions on the micro discharge preventing conductor rail. The air purification machine can kill bacteria and viruses, degrade organic compounds and remove particulate pollutants, the produced plasma has high concentration, ozone and oxynitride have low concentration without secondary pollution, and the sterilization effect is doubled. Moreover, the invention has the advantages of simple structure, energy saving, high reliability and long service life. The air purification machine is installed in an air duct of a central air-conditioning system and used for the air sterilization and purification of places such as hospitals, clean rooms, office buildings, shopping malls, hotels, theatres, airports, subways, and the like.

Description

Technical field: [0001] The invention belongs to the technical field of air disinfection and purification, and in particular relates to an air duct type electronic air purifier. Background technique: [0002] The air duct type electronic air purifiers currently on the market are installed in the air duct of the centralized air conditioning system, and some are installed at the air return port or the air supply port to purify the air in the room through circulation. They generally consist of metal filters, high-voltage ionizers, dust collection chambers, cold catalyst filters excited by ultraviolet lamps, and granular activated carbon filters. Most of the "heavy" particles are filtered through the electronic air cleaner's metal filter. Smaller particles are ionized by a high voltage as they enter the ionization zone with the airflow—giving them a positive charge. When the positively charged particles pass through the negatively charged dust collecting plate (output DC high ...
