Problems solved by technology

[0002] In the process of tunnel construction, when a hard mountain is encountered, it is necessary to use explosives to blast the mountain, and a large amount of dust is produced during the blasting. The dust in the tunnel is suppressed; in the prior art, the dust removal vehicle used for tunnel construction sprays the aqueous solution into the tunnel, so that the dust and the aqueous solution are fused and suppressed. When the explosive explodes, a large amount of potassium sulfide gas is generated, and the potassium sulfide gas is dispersed in the tunnel. Potassium sulfide is easily soluble in water and produces highly corrosive substances. There is a large amount of water in the atomization port of the dust collector to react with potassium sulfide, and the generated substances accumulate in the gaps at the edge of the atomization port for a long time. Accelerate the corrosion of the atomization port, and affect the normal atomization of the aqueous solution by the dust collector

Abstract

The invention discloses a dust removal vehicle for tunnel construction. The dust removal vehicle structurally comprises a transport vehicle, a water storage tank, a supporting table and an atomizing spray head, wherein the water storage tank is fixed at the top of the right side of the transport vehicle, the supporting table is mounted on the top of the right side of the transport vehicle and located on the right side of the water storage tank, and the atomizing spray head is movably clamped with the top of the support table. A dissolved potassium sulfide solution is scraped by collection heads of a solution collection device, and the situations that potassium sulfide emitted by blasting is dissolved in water, substances with strong corrosivity are generated, the generated substances are accumulated in gaps between an atomizing opening and edges of an atomizing net, so that the deterioration of the atomizing opening is accelerated, normal atomization of the dust removal vehicle to thewater solution is affected, and the solution scraped by the collection heads remains in a gap between the atomizing opening and a atomizing ring are prevented. The solution is isolated and collected through the collection heads, the collected solution is prevented from backflow, pollution gas in the solution is filtered, and pollution to the environment caused by direct discharge is prevented.
