The invention provides a device for quickly eliminating instantaneous smoke dust in a blasting operation space in a coal mine and a using method thereof, wherein the device comprises an underground compressed air pipeline, a negative pressure injection device, a multistage negative pressure dust suction device and a high pressure wet spraying device; the negative pressure power sucks the smoke dust through a multi-stage negative pressure dust suction device and performs separation; the flue gas after dust removal and high-pressure gas are mixed and enter a high-pressure wet spraying device, toxic and harmful flue gas is absorbed by organic active agent, and the clean gas and the moisture combined by the organic active agent are sprayed to an underground blasting operation space to implement further dust removal. The device has the advantages of small volume, convenient movement, simple operation, realization of industrial production and strong field practicability; the invention has the multi-stage linkage smoke dust eliminating function of absorbing dust under negative pressure, dissolving smoke gas by organic active agent and humidifying and reducing dust under high pressure, has high efficiency and good effect, and realizes effective treatment with low cost and high speed. |
