Title:
AIR-PURIFICATION STREET LAMP AND PURIFICATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/097949
Kind Code:
A1
Abstract:
An air-purification street lamp and a purification method thereof. The purification method of an air-purification street lamp comprises the following steps: monitoring traffic flow in real time by means of a traffic flow monitoring module, and sending the real-time traffic flow to a first processing module; comparing the real-time traffic flow with predetermined traffic flow, and when the real-time traffic flow is greater than the predetermined traffic flow, controlling, by means of a first control module, a fan to start so as to suck air into a housing; filtering PM2.5 particles; weighing, by means of a weighing module, a filtering layer adsorbing the PM2.5 particles, and sending the weight to a second processing module; and comparing the real-time weight with a predetermined weight by means of the second processing module, when the real-time weight is greater than the predetermined weight, controlling, by means of a second control module, a high-pressure air gun and an induced draft fan to start, blowing away the PM2.5 particles on the surface of the filtering layer using the high-pressure air gun, and sucking the blown-away PM2.5 particles into a collection box using the induced draft fan. According to the purification method, a purification device is started in the case of large traffic flow to achieve a purification function.
