Method for capturing PM2.5 fine particles

Abstract

The invention discloses an economical and practical method for capturing PM2.5 fine particles. Specific method: discharge the gas containing fine particles into a closed container full of air bubbles, and the air bubbles wrap the gas with fine particles and flow together to the exhaust port in the container. As a viscous flow carrier, the air bubbles provide the adhesive fine particles to detach. When the air bubbles burst, the adhered particles flow into the water storage tank along with the foam liquid to complete the purpose of capturing PM2.5 fine particles. Through trial on charcoal kilns, gasoline cars and bituminous coal-fired boilers, it is proved that this method can capture more than 80% of the fine particles generated, and particles with a particle size of ≥20 nanometers. The method is simple and easy to implement, and the effect is remarkable, and it is applicable to all walks of life that need to understand and solve inhalable particulate matter. The system is shown in Figure 1: intake pipe (1), bubble box (2), foamer (3), adherer (4), defoamer (5), exhaust pipe (6), dryer (7), accumulator Water tank (8), water pump (9), air pump (10), are connected with seamless pipe mutually.

Description

technical field [0001] The invention belongs to the field of dust remover technology Background technique [0002] Smog, with the development of human society, the degree of air pollution is becoming more and more serious. The new word smog appears very frequently, and it is often received on radio, TV, and text messages. The sunny and sunny days I yearned for when I was young have now become horrible days. Without the northwest wind, there will be smog. If there is no northwest wind for a week, there may be moderate smog, or even severe smog. Elderly people were warned to stop morning exercise, kindergartens and elementary schools were closed, the general public was advised to reduce outdoor activities, and traffic policemen stood guard with special masks on duty. The government has called on agencies at all levels to work hard to control air pollution. [0003] As we all know, the cause of smog weather is that the content of inhalable particulate matter such as PM2.5 in ...

AI Technical Summary

Problems solved by technology

PM2.5 inhalable particulate matter is a kind of fine particles suspended in the atmosphere. Past experience is to use dust collectors to remove particles in the air. Commonly used dust collectors include: gravity dust collectors, inertial dust collectors, cyclone dust collectors, Electrostatic precipitator, bag filter, self-excited precipitator, spray precipitator, Venturi tube precipitator and wet electrostatic precipitator. The above-mentioned precipitators cannot work on PM2.5 particulate matter in smog, organic particulate matter more powerless

[0004] So far, one of the main reasons for not effectively preventing and controlling smog is that the particles in the smog cannot be captured, and the composition and source of generation of particles cannot be clearly analyzed
