It uses air as main thing and uses water as auxiliary thing, and connects the high-pressure air pipe and low-pressure water pipe on the fan strip slot sprayer which can be regulated upward-downward and leftward-rightward, said sprayer also is equipped with a regulating bolt for regulating bearing of sprayer, so that it can make the atomized jet-flow be favorable for covering, screening, precipitating and removing dust, and can obtain obvious dust-precipitating and dust-removing effect, and its volume is small, structure is simple and cost is low.
Description
One, technical field
The present invention relates to a kind of high pressure draught injection atomizing de-dusting apparatus, be particularly useful for the control and the industrial and mineral cleaning project of down-hole, mine dust.
Two, background technology
Dust is as inevitable outcome, particularly one of Coal Production five the Nature disasters in the mining manufacturing process, and it not only causes occupational disease, and the harm worker is healthy, has explosivity simultaneously, and the safety in production of mine in serious threat.Particularly in recent years along with the raising of mining mechanization degree, face dust concentration is high always, and down-hole tool work plane is because himself production practice, and dust-producing amount is bigger.In order to arrive efficient volume increase and purpose of safety, the key issue that dust prevention and control has become new technology and new equipment to promote the use of is studied a kind of efficient spray device for reducing dust, and is healthy to the safety in production, the guarantee worker that guarantee work plane, has great importance.The capital equipment that is used for depositing dust at present has: High Pressure Spray for Dust Suppression device and coal-winning machine negative pressure secondary device for reducing dust, its nozzle mostly is made up of circular cone contraction section and cylindrical section, rely on high hydraulic pressure to produce water smoke, though these devices can play certain depositing dust effect, its operating pressure requires very high, usually more than 4Mpa, need to be equipped with special atomizer pump, and need special pressure duct and the high-pressure pump laid, its water consumption is big, it is many to take equipment, and use cost is higher.Because the water yield is excessive, very easily destroy ature of coal in addition; When dustproof water water quality is relatively poor, easily cause situations such as equipment shower nozzle obstruction, cause spray effect to reduce; In addition at stope, the geological conditions complexity is crossed tomography, when crossing situation such as weathered zone, because balk, existing atomizing de-dusting apparatus is higher again, can not guarantee the normal use of down-hole.
Three, technology contents
1. goal of the invention
In view of the deficiency that prior art exists, it is good to the purpose of this invention is to provide a kind of dust-laying effect, simple in structure, and cost is low, can regulate the high pressure draught injection atomizing de-dusting apparatus that area coverage is big.
2. technical scheme
A kind of high pressure draught injection of the present invention atomizing de-dusting apparatus, it comprises high-pressure air pipe and low pressure water pipe, described high-pressure air pipe and low pressure water pipe by valve nozzle be connected can about, on the Fan spray head of left and right adjusting, the nozzle of Fan spray head is a gap-shaped, also be provided with the adjusting bolt that to regulate bar seam nozzle orientation on the Fan spray head, regulate being bolted on the shower nozzle guard shield.
A kind of high pressure draught injection of the present invention atomizing de-dusting apparatus, its shower nozzle is fan-shaped, the bar seam nozzle limit wall symmetry of Fan spray head tilts, shower nozzle guard shield front end is downward-sloping and be fixed on the substrate, utilize the pressure of wind, make the dustproof moisture that enters gap-shaped wind-force driving nozzle be cleaved into many little water droplets, and be sprayed into spray at the shower nozzle place, outwards spray formation bar seam by the angled nozzle limit wall periphery that becomes symmetry and spray spray, become a fan-shaped spraying area, bar seam sprays spray and spreads along with the diffusion of air-flow and become turbulent flow, it is very good that the bar seam sprays spray decentralization under the impact of high velocity air, when bar seam injection spray is injected product dirt space, to produce the dirt space covers comprehensively, utilize and spray entrainmenting of spray, contact, inertia, diffusion, charged and dust-separation mist screen effect makes that dust condenses in the dust-contained airflow, air decontamination, thus reach depositing dust, the purpose of dust-separation and dedusting.
3. technique effect
A kind of high pressure draught injection of the present invention atomizing de-dusting apparatus is best suited for the depositing dust in mine down-hole coal excavation, driving face and tunnel.For reducing water consumption, reduce cost, cancellation pressure duct and high-pressure pump, the problems such as water content that improve on-the-spot applicability and reduce marketable coal are on the basis of prior art, employing is based on wind, with water is auxilliary, and the fan-shaped slit-aperture type high pressure draught injection atomizing de-dusting apparatus of geomantic omen combination has fundamentally solved the coal dust problem of getting working face, the generation of control dust explosion accident guarantees the safety in production of work plane.Create good working environment for work plane simultaneously, improve the output and the production efficiency of work plane.This equipment volume is little, does not need pressure duct and high-pressure pump, and cost is low, and applicability is strong; Can about, left and right adjusting, make dispersed jet help covering, shielding and depositing dust dedusting; Gap-shaped wind-force injection spray nozzle utilizes the pressure of wind, and the dustproof moisture of normal pressure is cleaved into many little water droplets, and atomizing effect is good, and the jet EFFECTIVE RANGE is big, utilizes and sprays the entrainmenting of spray, contact, inertia, diffusion, charged and dust-separation mist screen effect.Make that dust condenses in the dust-contained airflow, air decontamination, special better for the dust-laying effect of respirable dust, depositing dust efficient height, water consumption is low, can reduce the coal water content of work plane, guarantees the requirement of Coal Quality; Outer end at fan-shaped slit-aperture type high pressure draught injection fog-spray nozzle has added a protective cover, and the damage phenomenon to fog-spray nozzle that can avoid coal wall caving or fall to push up etc. caused plays the effect of protection fog-spray nozzle; increase the service life, its atomizing effect is good, and dust-laying effect is remarkable; safeguard function is complete, and volume is little, and cost is low; simple in structure; but the regulated at will fog-spray nozzle up and down and left and right directions, easy to operate, install simple; safeguard easily to have practicality widely.
