Device for sterilizing and purifying air in tunnel

Abstract

The invention belongs to the technical field of air sterilization and purification and particularly relates to a device for sterilizing and purifying the air in a tunnel. The device comprises a plasma reactor, a pulse power supply, a fan component, a controller, an air inlet, an air outlet and a housing, wherein the positive electrode in the plasma reactor is manufactured into a component by arranging a plurality of oxidation-resistant metal belts in the same plane in a way that the metal belts are parallel and equidistant, and the negative electrode therein is made from aluminum plates subjected to surface oxidation treatment and application of nano-scale TiO2 on both sides thereof; the device further comprises a plurality of micro-discharge-resisting conductor rails made from aluminum rods or stainless steel bars; and the two ends of the positive electrode are respectively fixed at the top end of a convex part of the corresponding conductor rail. The plasma and free radicals of the invention are capable of achieving the dual purposes of sterilization and disinfection, degrading contaminants and absorbing particulate matters; and the device of the invention has the advantages of simple structure, convenient installation, energy conservation, good reliability and long service life. The device of the invention is mainly applicable in tunnels, subways and underground garages and also applicable to the air sterilization and purification in families and public places, such as movie theaters, trains, cars, ships and the like.

Description

Technical field: [0001] The invention belongs to the technical field of air disinfection and purification, and in particular relates to a tunnel air disinfection purifier. Background technique: [0002] At present, the air pollutants in the tunnel are mainly exhaust gas and dust from motor vehicles, including CO, NO x and HC. Recently, someone at the entrance of the Dongshan Tunnel in Dinghai reported: "The dust and exhaust gas in the tunnel is relatively serious, especially the exhaust gas from large diesel locomotives. The tunnel is equipped with 2 groups of 8 fans for one-way exhaust. The exhaust fan can discharge exhaust gas and dust, but the fan itself has disadvantages: loud noise and high power consumption. Other similar problems often occur. [0003] For this reason, people in the industry carry out research and improvement. For example, the application number is 200810201240.2, the application date: 2008.10.16, and the invention name is "Tunnel Air Pollutant Pur...

AI Technical Summary

Problems solved by technology

However, with so many heating chambers and heating units, the processing air volume reaches 360,000-720,000 M 3 It is conceivable that the power consumption per hour is huge; at the same time, the temperature control of the long-term measurement and control module cannot be foolproof

In addition, the electrostatic precipitator is flushed after one week; a large number of catalysts and activated carbon must be replaced every 3-12 months

This is not only huge equipment, occupying a lot of land, high energy consumption, high maintenance costs, but also inconvenient to install and use.
