Method and device for air sterilization and dust removal in vehicle passenger room

Abstract

A device for air sterilizing and dust-removing in a passenger compartment of a vehicle comprises a plate-type electrode, a positive electrode sterilizing and dust-removing plate and a negative electrode sterilizing and dust-removing plate; the plate-type electrode comprises a positive electrode plate, a direct current voltage positive electrode for the positive electrode plate, a negative electrode outer frame, a direct current voltage negative electrode for the negative electrode outer frame, a positive electrode sterilizing and dust-removing plate and a negative electrode sterilizing and dust-removing plate; the positive electrode sterilizing and dust-removing plate comprises a positive electrode sterilizing and dust-removing plate supporting structure, a plurality blocks of positive electrode sterilizing and dust-removing composite material dust collecting plates are uniformly and vertically arranged on a positive electrode supporting structure, and an electrode applied by a positive voltage is arranged on the positive electrode sterilizing and dust-removing plate; the negative electrode sterilizing and dust-removing plate comprises a negative electrode sterilizing and dust-removing plate supporting structure, a plurality blocks of negative electrode sterilizing and dust-removing composite material dust collecting plates are uniformly and vertically arranged on a negative electrode supporting plane, and negative voltage is applied to the negative electrode sterilizing and dust-removing plate. The device can achieve low power and arc-free discharge, and simultaneously achieve efficient trapping of microorganisms and particles.

Description

technical field [0001] The invention belongs to the fields of air filtration, air cleaning technology, HVAC and microorganisms, and in particular relates to a method and device for air sterilization and dust removal in passenger compartments of vehicles such as high-speed rail EMUs and subway passenger compartments, which can effectively reduce the concentration of microorganisms such as bacteria and fungi in the air and particulate matter (PM2.5, PM10) concentrations. Background technique [0002] With the advancement of technology, the carriages (passenger compartments, buses, ships, and airplanes, etc.) of vehicles including high-speed trains, subways, etc. must maintain a comfortable temperature and humidity, but they are relatively dense spaces. During the process, the air in the space contains a variety of mixed microorganisms. The concentration of suspended microorganisms in the air mainly depends on the indoor hygienic conditions, passenger density, whether passenge...

AI Technical Summary

Problems solved by technology

The above method has the following disadvantages: (1) when the air filter filters the particulate matter, due to the large resistance, it is difficult to select the fan type for the high-speed rail EMU and the subway

For this reason, in order to reduce the resistance of the air filter, the selected air filter is usually of low efficiency and cannot achieve the function of sterilization; (2) the electrostatic precipitator is prone to generate ozone, which is unfavorable to the personnel in the passenger room of the relatively airtight vehicle
