Abstract

The invention discloses a testing method and apparatus for acquiring coagulation efficiency of a pollutant particle in different physical field environments. According to the invention, a compressed water-gas mixture is atomized by using an atomization nozzle; water mist passes through an electric field environment, so modified water mist is obtained, and the particle velocity and particle size of the modified water mist are detected by using a dynamic particle analyzer; then the atomization nozzle is closed, pollutant particle generation equipment is started, the particle concentration of the pollutant particle before coagulation is detected by using an electric low pressure impactor, and the particle velocity and particle size of the pollutant particle before coagulation are detected; and then the atomization nozzle is opened, the modified water mist is allowed to coagulate in fluid measurement and control equipment together with the pollutant particle, and the concentration of the residual pollutant particle is detected after settlement of a coagulation product. The electric field environment is changed into a magnetic field environment and a sound field environment, then the above-mentioned steps are repeated, and the particle concentrations before and after coagulation are compared so as to obtain the coagulation efficiency influence law curve of the pollutant particle in each physical field environment; and thus, powerful bases are provided for treatment of air pollution.

Description

technical field [0001] The invention relates to a measuring device, in particular to a test method and a test device for testing the collision efficiency of water mist on pollutant particles in different physical field environments. Background technique [0002] As the domestic air pollution problem is becoming more and more serious, in recent years, severe smog has frequently appeared in some areas of the country, which has brought a greater threat to the health of urban residents, aroused panic and widespread concern among citizens, and inhalable particulate matter is currently my country's The primary pollutant of urban air pollution. At home and abroad, the removal methods for fine particles in gaseous pollutants mainly focus on the micron-scale dry fog dust suppression method. This method mainly breaks water into water mist with a particle size of less than 10 microns through the nozzle. The dust in the air, especially the respirable dust particles with a diameter of le...
