The dust remover comprises a straight pipe, wherein one end of the straight pipe is provided with a water pipe, a gas pipe and a gas inlet, and the other end of the straight pipe is provided with a gas exhaust outlet; the gas outlet end of the gas pipe is arranged in the straight pipe; at least one gas nozzle is arranged at the gas outlet end of the gas pipe; and all gas nozzles are arranged towards the gas exhaust outlet respectively. The invention has the advantages that: (1) high-pressure gas is used for injection, the dust remover is not provided with moving parts and electrical appliance elements, and a service environment is not limited by gas density; (2) the dust remover has a simple structure, small volume and light weight and is convenient to carry, remove and mount quickly; and (3) the dust removing efficiency of the dust remover is not less than 95 percent at any concentration of dust contained in inflow air, so that the problem of clogging of the dust remover can be solved.
Description
Technical field
The present invention relates to the device of dust removal by ventilation under the coal mine, be mainly used in tunnel wall coal seam dry method boring dedusting, anchor pressure spray process depositing dust, coal conveying belt transfer point under the coal mine, refer in particular to a kind of underground mine use boring deslagging deduster.
Background technology
The existence of gas is threatening the safe working of coal in the coal seam, and the gas under the coal mine in the tunnel wall boring pump drainage coal seam becomes one important step of safe coal exploitation.To some weak seams, can only dry method hole, adopt compressed air drifting dust technology, the coal dust and the compressed air that produce when making boring spray along the gap between drilling rod and the hole wall together.Though the drifting dust gas flow is little, the energy that compressed air has is big, and the gas shock power of formation is strong, and the band dust quantity is up to 3000mg/m
3More than, cause the environment of work plane very abominable, the serious threat operating personnel's is healthy; The gas density height of ejection air-flow, because of the height safety in production needs, the dust-removing method of drifting dust technology is forbidden exhaust fan.
In order to improve the serious problem of environmental pollution in the dry method boring, present way is the aperture dust arrester that the drilling rod sleeve pipe is set in the aperture of dry method boring, small casing gos deep into the coal seam, big sleeve pipe is pressed close to the tunnel wall, compressed-air actuated drifting dust enters big sleeve pipe along the ejection of the gap between drilling rod and the small casing, and at big sleeve pipe internal spraying depositing dust, efficiency of dust collection is between 50%～60%, though dust-laying effect is obvious, be difficult to reach working envrionment sanitary standard.At present, the aperture dedusting also has the process equipment of other form, as multi-stage non-powered orifice dust remover (200920032546.X), mining wet type orifice dust catcher (200620110816.0), but because equipment volume is big, remove fast, dress and difficult, be difficult to adapt to the frequent demand of changing of bore position.
Fast development along with national economy, the demand of coal is increasing, the safe working of coal is more and more paid attention to, and tunnel wall boring pump drainage gas has become one of important measures that gas is given prominence in the prevention coal mining, so the boring workload in wall coal seam is increasing.In order to eliminate in the dry method boring procedure dust to the threat of operating worker, the development volume is little, in light weight, safe and reliable, remove and adorn fast and easily that the high-effective dust-removing device has important practical value, it can improve the working environment of work plane, reduce the labour intensity of operating worker, ensure the working interest of operating worker, simultaneously, can improve the operating efficiency of wall boring.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, a kind of underground mine use boring deslagging deduster is provided, deduster has adopted gases at high pressure injection principle, wet dedusting technology, it is simple in structure, volume is little, in light weight, carrying is efficient and convenient and efficiency of dust collection is high.
