Abstract: Disclosed is a microscopic comparison and experimental verification method for the wettability of similar surfactants on coal dust, comprising: collecting a coal sample on site from a mining area and analyzing the coal sample by infrared spectroscopy and nuclear magnetic resonance spectroscopy to obtain information on functional groups and carbon structure of coal molecules; S2: constructing a surfactant-coal molecule electrostatic interaction model and analyzing an orbital energy difference and an electrostatic potential difference between surfactant molecules and coal molecules, etc. S6. The invention provides a simple and effective idea for the selection of surfactants.

Abstract: A swirl structure-based exhaust aftertreatment device for an underground mining diesel vehicle comprises a water tank, a PM collection tank, an inlet tube, a high-speed rotary exhaust separator, an exhaust catalytic converter, a circulating NOx selective catalytic reduction system and an exhaust tube. The high-speed rotary exhaust separator comprises a Laval tube, a throat tube, a swirl tube and a first deposition tube. The concentration of toxic and harmful components in exhaust can be decreased below a concentration threshold, thus avoiding pipeline blockage caused by PM accumulation.
