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.
