Regional air purification system

Abstract

The invention relates to the field of air purification and provides a regional air purification system. The regional air purification system comprises a waste oil recycling and separating device, a plasma purification device, a centrifugal fan, an ultrasonic atomization device and a negative ion generation device. An air outlet of the ultrasonic atomization device and an air outlet of the negative ion generation device are each provided with a releaser. According to the regional air purification system, electricity generated by clean energy such as wind energy and solar energy is used as a main power supply source, and the technology is feasible and meets the national industrial policies of energy saving and consumption reducing. Through the technology, a large amount of waste cooking oil can be efficiently separated out, and resource utilization of waste is achieved. The technology has the multiple purification function, the purposes of humidifying the regional environment, purifying PM2.5 in the regional environment and constructing the regional oxygen-enriched environment are realized, and later hidden danger such as secondary pollution cannot be produced. The technology is integrated in an integrated device, and transportation and installation are convenient and rapid. Meanwhile, a complete programmable logic controller (PLC) automatic control system is arranged, and thus automatic switching or remotely-controlled switching of different functions can be achieved according to time periods or ambient air pollution indexes.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a regional air purification system which takes oil fume exhaust gas purification as an entry point and centralizes point source pollution so as to effectively solve local surface source pollution. Background technique [0002] According to the investigation of relevant departments: the formation of haze pollution is closely related to the increase of the concentration of fine particles in the atmosphere. About 10% of fine particulate matter comes from natural emissions, and nearly 90% comes from man-made emissions. Its source apportionment results for PM2.5 in Beijing show that coal burning and motor vehicles are the main sources. In Beijing’s annual average PM2.5 emissions, coal combustion accounts for 26%, motor vehicles 19%, catering 11%, and industry 10%. It can be seen that the impact of soot emissions from the catering industry on the atmosphere cannot be underestimated. ...

AI Technical Summary

Problems solved by technology

In today's era, there are many types of indoor air purifiers with different brands and single functions. Although they can solve the problem of local air pollution, point source pollution control can never solve the problem of non-point source pollution, and ultimately cannot obtain satisfactory results.
