Description
Technical field:
The present invention relates to a kind of method for arranging of ventilating and purifying air system, particularly relate to the method for arranging of the digging laneway aerating and dust removing system of concentrating in a kind of suitable mine working driving and highway, railway, subway tunnel driving and dirt source.
Background technology:
Dust is mining excavation tunnel, and one of main natural calamity of highway, railway, subway tunnel driving, and along with improving constantly of mechanization level, the generation of dust is increasing, surveys dust concentration when showing the machine pick factually up to 1000-3000mg/m
3, and the decentralization height, wherein particle diameter accounts for more than 85% less than the respirable dust of 7 μ m, serious threat field operation personnel's safety and healthy.At present domestic cleaner is of a great variety, and general equal dust removing effects is not good enough.Except the efficiency of dust collection problem of deduster, main problem is the ventilating and purifying air system Layout Problem, great majority are that ventilating and purifying air system is when arranging, be that the new wind that will be pressed into is directly sent into work plane, the dust that heading equipment is produced dispels, this method for arranging, dust arrester are pounced on and are caught the dust difficulty, and dust removing effects is poor.
Summary of the invention:
The present invention is directed to the prior art dust arrester frequently moves, installs, the negative pressure air duct is hung repeatedly, pounce on and catch the dust difficulty, many deficiencies of dust removing effects difference, a kind of long short dust removal by ventilation mode of taking out of pressing that adopts is provided, good dedusting effect, the method for arranging of the simple digging laneway aerating and dust removing system of operation.
Realize the foregoing invention purpose by the following technical solutions: a kind of method for arranging of digging laneway aerating and dust removing system, comprise development machine, belt conveyor, belt rehandle facilities, dust arrester and ventilation installation, described development machine docks with the belt rehandle facilities; Rehandle facilities is erected on the belt conveyor; The negative pressure air duct of ventilation installation is hung on the tunnel and the blower fan clamp connection; Blower fan is erected on the fan supporter; The malleation air duct of ventilation installation is provided with two, malleation air duct and blower fan clamp connection, and with the deduster clamp connection, another malleation air duct and cyclone adopt clamp connection also to hang on the tunnel; The deduster of dust arrester is erected on the deduster bracing or strutting arrangement; Described dust arrester is arranged in 20-40 rice, development machine back, and is connected to apart from development end 3-5 rice of meeting head on the negative pressure air duct, and new wind is pressed into outlet apart from meeting head on 15-35 rice by the malleation air duct.
Adopt technique scheme, compared with prior art, the present invention is arranged in cleaner in the back 20-40 rice of heading equipment, with the negative pressure wind socket joint to about 3-5 rice of meeting head on apart from development end, new wind is pressed into outlet apart from meeting head on 15-35 rice for the malleation air duct by forced ventilation equipment, swirl-flow devices is also installed in outlet additional, and calculates the air quantity of supporting cleaner and forced ventilation equipment according to drift section etc.This long short ventilating and purifying air system method for arranging of taking out of pressing, solve the problem of prior art ventilating dust-removing effect difference, existing six kinds of arrangement forms commonly used make the total efficiency of dust collection of digging laneway aerating dedusting up to 98%, the respirable dust efficiency of dust collection is up to 90%, also reduced simultaneously because of using dust arrester to influence the drawback of development machine Homes Using TV, really reached mining excavation tunnel, and the ventilating dust-removing effect of highway, railway, subway tunnel driving.And have that ventilation connection and reasonable arrangement, security performance are good, conveniently moving, simple to operate, good dedusting effect, advantage such as water consumption is low, cost is low.It is the comparatively best method for arranging of the dust removal by ventilation of the present mine of China, highway, railway, subway tunnel driving.
