Air purifying street lamp based on multi-component nano materials

Abstract

The invention relates to the technical field of environmental protection, in particular to a novel street lamp with the air purifying function and multiple nano material components. According to the air purifying street lamp based on multi-component nano materials, an air purifying solution is prepared from the multi-component nano materials, so that the purposes of absorbing flying dust, decomposing pollutants, killing germs and purifying air are achieved. The air purifying street lamp based on the multi-component nano materials has the advantages of being low in using cost and easy and convenient to clean and maintain.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a novel street lamp with air purification function using various nanometer material components. Background technique [0002] The progress of society, the rapid development of economy and the continuous prosperity of industrial production have prompted the increasing number of urban motor vehicles. The dust and exhaust emissions brought by motor vehicles have led to increasingly serious urban air pollution, followed by PM2.5 and other air pollution. The indicators seriously exceed the standard and the repeated occurrence of smog weather not only has a serious impact on urban traffic, but also brings serious harm to the health of residents and hinders the further development of the social economy.

[0002] The progress of society, the rapid development of economy and the continuous prosperity of industrial production have prompted the increasing number of urban motor vehicles. The dust and exhaust emissions brought by motor vehicles have led to increasingly serious urban air pollution, followed by PM2.5 and other air pollution. The indicators seriously exceed the standard and the repeated occurrence of smog weather not only has a serious impact on urban traffic, but also brings serious harm to the health of residents and hinders the further development of the social economy. Therefore, a close-range and efficient collection of motor vehicle dust and Vehicle exhaust device, which is an important part of controlling urban air pollution and preventing smog

[0003] The utility model patent (application number: 201320611531.5) discloses a design scheme of an outdoor haze removal machine. The basic principle is to use the spraying effect of water to absorb the haze, which has certain practical significance. The main pollutants such as benzene, formaldehyde, sulfide, ammonia and other organic compounds and inorganic substances, as well as viruses and bacteria in the air have little or no effect. Therefore, the air purification effect of this scheme is not good, especially When this device is installed on the side of the urban road where dust and vehicle exhaust are likely to gather, it needs to occupy a lot of urban land, resulting in a great waste of urban land resources

[0004] Invention patent (application number: 201310468996.4) discloses a street light pole for dust removal, smog and haze purification, which is composed of the light pole, lighting and other main structures, as well as the filter screen and dust collection box installed in the light pole. The filter inside can block the smog. Its advantage is that the air purifier can be combined with the street lamp, which can be used for multiple purposes, reduce the land occupation, and save valuable urban land resources. The generation point is short and the absorption efficiency is relatively high, but its disadvantages are also obvious. Due to the filter mesh structure, when the filter mesh pore size is too large, it will lose the ability to absorb sulfide, ammonia and other organic compounds and inorganic substances, as well as viruses and bacteria in the air. When the pore size of the filter is too small, large molecular particles such as car dust are easy to block the filter, resulting in the need to replace the filter frequently, and the cost of use is high, especially for large-scale cleaning and maintenance when used on a large scale. Net is very troublesome
