Vehicle-mounted high-efficiency pm2.5 particle interception device

Abstract

The invention discloses a vehicle-mounted efficient PM2.5 particle cutting and extinguishing device, and belongs to the technical field of air cleaning. The vehicle-mounted efficient PM2.5 particle cutting and extinguishing device structurally comprises a through shell provided with an air inlet and an air outlet, wherein the space in the shell is sequentially provided with an air flow guiding area, an ionization area, an adsorption area and a guiding and emitting area according to the charge and discharge directions of air flow; the shell is provided with a base; the base is provided with an ash storage tank communicated with the adsorption area. The key point is that the air flow guiding area is internally provided with a controllable air adjusting grating and a distributary channel; the ionization area is internally divided into ionization area horizontal air flow channels and ionization area axial air flow channels by high-voltage-difference substrate groups; the adsorption area is internally and centrally provided with a cathode plate, a deflection electric field device consisting of symmetrically arranged anode plates and an adsorption area axial air flow channel; an interception grid screen plate is arranged between the adsorption area and the guiding and emitting area. By combining with the device, an automobile can become a mobile device with an air purifying function; particles in hazy air are adsorbed by utilizing a great amount of running automobiles in cities, so that the percentage of the particles in hazy air can be reduced greatly; the probability of occurrence of haze disastrous weather is reduced.

Description

technical field [0001] The invention belongs to air cleaning public welfare technology, and relates to a PM2.5 particle adsorption device, in particular to a vehicle-mounted high-efficiency PM2.5 particle cut-off device. Background technique [0002] With the acceleration of the modernization process, the improvement of urban construction and industrialization level, environmental protection issues have become increasingly prominent, especially in the smog weather caused by the operation of urban vehicles, heating coal in winter, and industrial production. The weather is harmful to human health and affects people's travel safety. [0003] Smog is mainly composed of three items: sulfur dioxide, nitrogen oxides, and particulate matter. The first two are gaseous pollutants, and the last item, particulate matter, is the culprit that aggravates the pollution of hazy weather. The English abbreviation of particulate matter is PM, often referred to as PM2.5, that is, pollutant part...

Problems solved by technology

[0004] For the new disastrous weather such as smog, there are currently more professional and effective methods to control it in China. Most people use masks to prevent and control it. However, smog is a kind of small molecular particles, and the average aperture of a mask is smaller than that of particles. The diameter of the smog should be large, so the effect is not obvious, and it cannot solve the harm of smog to people's health.
