Problems solved by technology

(2) There is a temperature inversion in the vertical direction, and the temperature inversion at high altitudes is higher than that at low air temperatures, which restricts the vertical movement of air at low altitudes in the atmosphere
[0010] At present, the existing solutions have complex structures, and high production and operating costs (such as the authorized announcement: CN103111146 A, a patented solution for a device for watering and alleviating urban smog); or the device has low operating efficiency, except The haze effect is uncertain (such as the authorized announcement: CN 103174663 A, the patented haze weather prevention machine scheme) and other shortcomings
[0011] At present, there is no artificial method and special equipment to effectively reduce the concentration of smog in a city

Embodiment 1

[0059] Example 1, as shown in Figures 1 and 3, the atmospheric dust collector is an air purification device with an electrostatic precipitator as the core. The air inlet is a rectangular box with a height of 300mm and a width of 2250mm and a length of 2150mm; its overall shape matches the top of the bus. Mounted on the rear roof of the bus, on the outside. Shown is a partial side view of a bus with atmospheric dust collectors installed. In the above air purification process, the power consumed comes from photovoltaic power generation, car idling or low-speed operation power generation, and car braking and deceleration energy collection to generate power. These electricity can be stored in the capacity 12H lithium series rechargeable battery on the roof. There is also a super capacitor box in the power buffer circuit. Under normal circumstances, even on cloudy days, the above-mentioned electricity can keep the air purification system working. When the battery is really low,...

Embodiment 2

[0060] Example 2, as figure 2 Shown is a special vehicle for air purification. The upper part of the vehicle is an air purification device that uses liquid washing and adsorption as a working unit. When the vehicle moves, the air passes through the air purifying device; the air purifying device has an air inlet and an air outlet, and a box with open ends composed of an internal purification unit or purification component; there are louver components at the air inlet, which can adjust the wind speed and block the air. The role of rain and snow; there is a metal mesh in front of or behind the air inlet louvers, and the metal mesh plays the role of blocking leaves, paper, plastic bags and other sundries. There is a device for adjusting the wind pressure inside the air outlet of the air purification device. The device for adjusting the wind pressure is a large fan; when the wind pressure is too large, the fan is a wind generator; it plays the role of recovering energy and adjusti...

Embodiment 3

[0061] Example 3, as figure 1 The bus shown is equipped with an on-board atmospheric dust collector, which becomes a "city vacuum cleaner" bus, which can not only reduce its own pollutant emissions, but also absorb more surrounding air pollutants.

[0062] The air inlet of the vehicle-mounted atmospheric dust collector is a rectangular box with a height of 300mm, a width of 2250mm and a length of 2150mm; the interior is mainly an electrostatic precipitator to purify the haze air pollutants, and the air flow of a bus at a speed of 15 kilometers per hour. The treated air volume is approximately 10,000 cubic meters per hour. In the purification effect of electrostatic precipitator, the dust removal filter is as high as 95 to 99%; the PM2.5 concentration of the purified air is within the scope of the national first-class air standard, and it is high-quality air.

[0063] In order to improve the effect, 2,000 vehicles are specially added for special air purification; each vehicle ...

Abstract

The invention relates to an economical method for reducing the concentration of urban haze. The method is characterized in that a special movable high-ventilation-volume air purifying device is used and produced into a special motor vehicle and a special trailer or a trailer for a track; the high-ventilation-volume air purifying device is arranged on the motor vehicle and can be used for purifyingair flowing through the device; when numerous movable high-ventilation-volume air purifying devices move in a city, a large amount of air can be purified, and the concentration of haze is reduced. Ifthe movable high-ventilation-volume air purifying devices are arranged on 21,000 buses in Beijing, 200 million cubic meters of air can be purified in each hour, and 2 billion cubic meters of air canbe purified each day. The qualities of air on two sides of a road can be improved to a certain degree; the qualities of the air on the two sides of the road can be effectively improved within a fleeting time.

Description

【Technical field】 [0001] The invention relates to the field of environmental protection, in particular to a method for reducing the concentration of urban haze by carrying an air purification device on a mobile vehicle. 【Background technique】 [0002] Smog is the general term for fog and haze. [0003] Sulfur dioxide, nitrogen oxides and inhalable particulate matter are the main components of smog, the first two are gaseous pollutants, and the last particulate matter is the culprit of aggravating haze weather pollution. They combine with fog to instantly turn the sky grey, affecting visibility. The English abbreviation of particulate matter is PM, which is often referred to as PM2.5, which is pollutant particles with a diameter of less than 2.5 microns. Sources of toxic particulate matter in cities: vehicle exhaust, especially large vehicles that use diesel, is a “serious offender” of PM2. Road dust caused by sports. [0004] Fog is an aerosol system composed of a large ...
