Description
Technical Field
The utility model relates to a return coal tunnel no tuber pipe ventilation system belongs to colliery ventilation technical field.
Background
The coal return tunnel is an underground coal conveying building which is frequently arranged in a coal storage plant and a power plant, because the coal return tunnel is arranged underground, the natural ventilation effect is poor, the working environment of an inspection worker is improved, and meanwhile, the replacement treatment of the air of the coal return tunnel is needed for removing the humid air and partial dust in the tunnel, the conventional method for ventilating the coal return tunnel at present is to arrange a steel ventilating duct at the top of a tunnel overhaul channel, the ventilating duct is arranged in the tunnel and occupies the space of the tunnel, so the net height of the tunnel needs to be increased by 2.5 meters, the civil engineering quantity is increased invisibly, and the ventilating duct needs to be provided with a high-power and high-rotating-speed explosion-proof ventilator for overcoming the resistance generated by the ventilating duct, and the high-power and high-rotating-speed explosion-proof ventilator can consume a large amount of electric energy when in operation, generates extremely large noise, has serious noise pollution and has large installation difficulty, the installation and operation costs are high.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes prior art exists not enough, provides a simple structure, simple to operate's return coal tunnel does not have tuber pipe ventilation system.
In order to solve the technical problem, the utility model discloses a technical scheme be: the utility model provides a return coal tunnel no tuber pipe ventilation system, returns coal tunnel one end and sets up natural air intake, and the other end sets up the roof ventilation blower, and natural air intake all sets up subaerial with the roof ventilation blower, and natural air intake and roof ventilation blower are linked together with returning the coal tunnel, and natural air intake, return coal tunnel, roof ventilation blower form U type structure, and the roof ventilation blower links to each other through pre-buried tuber pipe with returning between the coal tunnel.
The natural air inlet is provided with a rainproof air inlet shutter, a coarse filter and a fireproof air port from outside to inside in sequence.
And an anti-falling net is arranged at the position where the pre-buried air pipe is communicated with the coal return tunnel.
And a normally open fire valve is arranged on the embedded air pipe.
And a ventilation pipeline is not arranged in the coal return tunnel.
The roof ventilator is an explosion-proof fan.
Guard rails are arranged around the roof ventilator.
Compared with the prior art, the utility model following beneficial effect has: the natural air inlet and the ventilator are respectively arranged at the openings at the two ends of the coal return tunnel, and an air pipe is not arranged in the coal return tunnel, so that the height of the coal return tunnel is not required to be increased, the civil engineering quantity is not increased, the installation and construction period of the ventilation system can be greatly shortened, and the cost and the operating cost are saved.
Drawings
The present invention will be further described with reference to the accompanying drawings.
