Description

Solar outdoor haze purifier

technical field

The invention relates to the field of environmental protection, in particular to a solar outdoor haze purifier.

Background technique

An air purifier is a device that can absorb various pollutants in the air, kill bacteria, and improve air quality. At present, most air purifiers are used indoors, in underground spaces, and in cars. They have a limited range of use and cannot meet the needs of people's daily life. They also consume a lot of energy, are heavy, occupy a large area, and are expensive.

In recent years, air pollution in China has been serious, with smog affecting 25 provinces and more than 100 large and medium-sized cities. The national average of smog days has reached 29.9 days, the highest in 52 years. The occurrence frequency of smog is high, the spread is wide, the pollution level is unprecedented, and the PM2.5 index is off the charts. According to data from the U.S. Embassy in Beijing, during the eight years from 2008 to 2015, Beijing’s air pollution has been in the range of 90-100 μg/m3, which is five times the World Health Organization’s 24-hour upper limit. Therefore, air purifiers have become popular in China where air quality is declining, especially air purifiers that can filter PM2.5. Today's air purifiers are mostly indoor air purifiers, which are difficult to absorb harmful gases from automobile exhaust and factory emissions, and these two polluting gases are the main culprits of air pollution.

The press-in fan makes the polluted air flow into the purification system, is processed by a multi-stage purification device, and finally returns to the atmosphere through the air outlet.

In order to achieve the above object, the technical solution adopted in the present invention is: the solar outdoor haze purifier is composed of a solar panel, a press-in fan, an initial effect filter system, a medium effect filter system, a high efficiency filter system, and a PM2.5 automatic monitor , telescopic air duct and battery. The primary filter system is composed of primary filter screen and Naweika, which can remove impurities and large particle air pollutants in the air. The intermediate filter system is composed of AV990 sterilization sheet and pure diatom filter sheet, which can kill 90% of bacteria in the air, reduce 60% of harmful gases and inhalable particles in the air, and greatly improve the air quality. The filtration system is composed of HEPA high-efficiency filter sheets and composite high-efficiency filter screens. This layer of filtration system can filter harmful particles with smaller particle sizes to achieve the ideal purification effect.

The interval between the AV990 sterilizing sheet and Naweika is 7cm, the interval between the diatom pure filter sheet and the AV990 sterilizing sheet is 5cm, and the HEPA high-efficiency filter is closely connected with the composite high-efficiency filter. The space between the filters is 7cm.

The air outlet net solar outdoor haze purifier is placed on a street light pole 500cm away from the ground, the solar panel shell is 80cm high, and the lower end is connected to a telescopic air duct with a length of 120-220cm, and the bottom connection length of the telescopic air duct is 15cm The air outlet net can reach 200-300cm from the ground.

Compared with the prior art, the present invention has the following advantages: 1. The air quality after filtration is improved by adopting a multi-stage filtration system, and the contradiction between air pollution and resource shortage is alleviated by using solar energy as a power source, and the working efficiency is optimized and improved. The product operates stably and has a high utilization rate; 2. Solar power is used to provide power, and the collection of power generation and purification are carried out simultaneously, which increases the flexibility of use, greatly reduces the operating cost of the product, and is relatively simple to install; 3. Shared with street lights The pole not only realizes the possibility of high-altitude purification but also greatly improves the space utilization rate on both sides of the road. The product installation cost is low, saves resources, and contributes to the improvement of urban air quality; 4. On the one hand, the intelligent monitoring system provides a basis for the normal operation of the equipment , in order to facilitate the repair and maintenance of the equipment, on the other hand, it can also test the working quality of the equipment to achieve the best filtering effect.
