Public infrastructure based PM2.5 purification device having PM2.5 detection function

Abstract

The invention provides a public infrastructure based PM2.5 purification system having a PM2.5 detection function. The system comprises public infrastructure (such as landscape lamps, streetlamps, traffic signals, electronic probes, street or building colored lights, LED display screens, buses, and electronic bus stations) convenient to power, and a PM2.5 purification device installed on the public infrastructure. The PM2.5 purification device can produce negative ions by means high tension ionization so as to purify PM2.5 in the atmospheric environment. The PM2.5 purification device is equipped with a PM2.5 detection module, current air quality of a public infrastructure location can be detected in real time, and on-off state and negative ion generation power of the PM2.5 purification device are intelligently controlled according to detection results. The system has the advantages that the PM2.5 in the atmospheric environment can be purified intelligently and energy resources are saved.

Description

technical field [0001] The invention relates to an atmospheric environment improvement system based on public infrastructure, in particular to a PM2.5 purification device with its own PM2.5 detection function. Background technique [0002] With the emergence of large areas of smog in our country, the problem of air pollution, especially the concentration of PM2.5, has become one of the problems that need to be solved and improved in the world. PM2.5 refers to particulate matter with a diameter of 2.5 microns or less. It can be suspended in the air for a long time, and the higher its concentration in the air, the more serious the air pollution. Compared with coarser atmospheric particles, PM2.5 has small particle size, large area, strong activity, easy to attach toxic and harmful substances (such as heavy metals, microorganisms, etc.), and has a long residence time in the atmosphere and a long transportation distance. Therefore, it has a greater impact on human health and a...

Problems solved by technology

[0004] Existing PM2.5 purification devices, one is to use physical and chemical methods to purify, that is, to reduce the PM2.5 content in the air through physical adsorption or chemical reaction, but it is necessary to replace physical adsorption or chemical reaction materials regularly, and the waste of resources is serious

The other is to reduce the PM2.5 content in the air by generating negative ions through high-voltage ionization, but this method is continuous and uninterrupted purification, if you want to stop, you need to manually intervene on site

It is impossible to use the device itself to intelligently judge the external atmospheric environment whether it is necessary to start and stop the PM2.5 purification device, and it is also impossible to intelligently adjust the purification power of the PM2.5 purification device according to the PM2.5 content in the atmospheric environment
