Embodiment 1

[0036] A kind of method that utilizes laser to purify air, its specific process of preparing purified air is as follows:

[0037] The compressed air is obtained by isothermally compressing the air through a rotary air compressor. The power of the compressor is 140kW, and the external compression ratio is 5. Then, the compressed air is cooled to -5°C by refrigeration equipment, and supersaturated moisture is precipitated. After the temperature rises, Obtain dry compressed air with a moisture content of less than 0.05%; pass the dry compressed air through a high-voltage electrostatic field, so that harmful substances in the air are directly exposed to the high-voltage electric field, and the air molecules are ionized into positive ions and electrons in the strong electric field. When encountering dust particles, the dust particles will be negatively charged and collected by the positive electrode to remove the dust particles in the air. The electric field voltage is 80kV and the ...

Abstract

The invention belongs to the technical field of air purification, and provides a method for purifying the air by utilizing lasers. The method comprises the steps that the air is subjected to dust removing treatment in a high-voltage electrostatic field after being compressed and dehydrated, then the air is treated in a treating pond of a laser system, the laser system conducts rectification on thesystem by arranging a plurality of photoelectric receivers, and accordingly high-efficiency purification of the air is achieved. Compared with a traditional method, a laser power source adopted by the treatment method is stable, the purification effect is good, the maintenance time is long, and meanwhile, the whole process is simple and convenient to operate, the cost of equipment manufacturing,operation and maintenance is relatively low, and the method can be applied and popularized on a large scale.

Description

technical field [0001] The invention belongs to the technical field of air purification and provides a method for purifying air by using laser light. Background technique [0002] Air pollution refers to the discharge of various pollutants into the atmosphere from human production, living activities or nature, the content of which exceeds the carrying capacity of the environment, deteriorating the quality of the air, and causing adverse effects on people's work, life, health, equipment and property, and the ecological environment. and destruction. Air pollution pollution sources can be divided into natural pollution sources and man-made pollution sources. Natural pollution sources refer to the places or areas where pollutants are discharged into the atmosphere in nature. Man-made pollution sources can be divided into domestic pollution sources, industrial pollution sources, traffic pollution sources, etc. according to people's social activities. Industrial waste gas, indu...
