Problems solved by technology

[0004] In order to overcome the gas concentration in the underground air, the concentration in the ventilation duct will gradually increase. When the gas explosion concentration limit is reached, there will be a danger of gas explosion, and the dust in the underground air will not be treated in time after settling, which will pollute the equipment. The shortcoming of this invention provides a kind of explosion-proof and dust-proof ventilating equipment for underground engineering

Abstract

The invention relates to the field of underground engineering, in particular to explosion-proof and dust-proof ventilation equipment for underground engineering. The technical problems that the concentration of gas in underground air in a ventilation pipeline can be gradually increased, when the concentration reaches a gas explosion concentration limit value, the danger of gas explosion exists, and dust in the underground air can pollute equipment due to the fact that the dust is not treated in time after settling are solved. According to the technical scheme, the explosion-proof and dust-proof ventilation equipment for the underground engineering comprises an adapter pipe, a fan and the like; the right side of the adapter communicates with a fan. Air with gas is intermittently injected into the closed space, and then the gas is ignited, so that the concentration of the gas in the underground air is reduced, and a large amount of gas cannot be ignited; and after the dust is sprayed and settled, the dust settles again in turbid liquid, so that the dust is accumulated and collected, and manual removal is facilitated.

Description

technical field [0001] The invention relates to the field of underground engineering, in particular to an explosion-proof and dust-proof ventilation device for underground engineering. Background technique [0002] In the prior art, the ventilation of the underground project is only the exchange of air. When the underground air is pumped into the ventilation duct by the fan, the gas concentration in the underground air will gradually increase in the ventilation duct. When the gas explosion concentration is reached. When the limit value is reached, there is a danger of gas explosion, and the underground air contains a large amount of dust, which directly discharges and pollutes the outside air, and directly sprays and settles. If it is not cleaned in time, it will also pollute the ventilation equipment and reduce the service life of the ventilation equipment. , and when the gas concentration suddenly rises to the gas explosion concentration limit, there is no ability to quick...
