Abstract
The invention discloses a method for generating power by mine exhaust cyclic utilization, comprising the following steps: an air collector is arranged at the external part of a mine outlet, the cross section of an air inlet of the air collector is larger than that of the air outlet, and a wind driven generator is arranged at the air outlet of the air collector to utilize strong air current at the air outlet of the air collector to generate power. By adopting the technical scheme of the invention, exhaust from the mine is effectively utilized to change waste into treasures, so that energy can be used effectively, a complicated design for the generator for adapting to wind directions and wind power which are converted ceaselessly is avoided due to stable and endurable air-out wind speed and no influence of air current change in an external environment, thus lowering the implementation cost greatly and simplifying the required equipment.
Description
Technical field
The present invention relates to utilize the useless wind of mine as the useless recycling method of wind of a kind of mine of wind-power electricity generation power.
Background technique
The colliery is the large electricity consumer in the national economy.Mine ventilation is the lifeline of Coal Production, and it supplies with the enough fresh airs of personnel in the pit (1), satisfies personnel's besoin de respirer.(2) water down eliminating down-hole toxic gas and dust, guarantee that the staff does not poison, keep the turbidity test of air, to prevent gas and dust explosion accident.(3) down-hole heat and water vapour are got rid of in dilution, create the appropriate climate environment, improve worker's working condition, guarantee personal safety and mine safety production.Therefore, each mine must have two well heads at least, an air intake, a return air.Ore deposit long old mine in age along with digging is extended, even will be built 2～3 return air shafts.At each return air well head large-scale ventilator (medium-sized mine installing 6000v is installed; Two of 315kw counter rotating axial fans), around the clock down-hole vitiated air and harmful gas were discharged to ground in 24 hours.So in Coal Production, ventilator becomes the current consuming apparatus of colliery maximum.And from the wind energy resources that the off-gas flows that mine is discharged down produces, never come into the picture year after year, slatterned in vain.
In the process that the off-gas flows that mine is discharged utilizes, need address the problem: 1. whether mine ventilation is smooth and easy is a major issue of relation safety production and miner's life safety.When the waste gas that mine is discharged utilizes, must at first guarantee mine ventilation smoothly; 2. the off-gas flows wind speed of mine discharge is about 15m/s, and wind speed is less, and generating efficiency is lower.Because above problem, mine can't be realized by useless the recycling of wind for a long time.
Summary of the invention
The present invention is the down-hole off-gas flows that utilizes mine ventilating shaft mouth to discharge, supercharging wind-drive device through being installed in the ventilating shaft exhaust outlet is collected, drive the turbofan generator for electricity generation, after friendship-friendship inversion, boost by transformer and to incorporate power supply grid into, realize that useless wind is recycling, the purpose that reach energy-saving and cost-reducing, turns waste into wealth.
For achieving the above object, the technological scheme that the present invention takes is: comprise the steps: to establish wind-drive device at mine exhaust outlet place, wind-drive device wind inlet cross section is greater than wind-drive device exhaust outlet cross section, at wind-drive device exhaust outlet place wind-driven generator is installed, is utilized the airflow generating at wind-drive device exhaust outlet place.
Comprise also that preferably described wind-drive device wind inlet cross-section area should be not less than mine exhaust outlet cross-section area twice.
Comprise also that preferably described wind-drive device wind inlet and mine exhaust outlet are separated, to guarantee the normal ventilation of mine inside.
Comprise also that preferably described wind-drive device wind inlet and mine exhaust outlet distance is not less than 1 meter.
Adopt technique scheme, beneficial technical effects of the present invention is:
1. utilize wind energy resources that the off-gas flows of discharging down from mine produces to generate electricity as the power of wind-power electricity generation, all can use in the place that needs mine for air exhaustion, different with other method of utilizing natural wind to generate electricity, this method is not subjected to the restriction of natural airflow condition, be not subjected to the influence of mine external environment condition climatic change yet, can keep the state of monsoon intensity lasting stability.So just avoid generator is carried out wind direction and the wind-force of somewhat complex design to adapt to continuous conversion, can obviously reduce the cost of enforcement, simplify equipment needed thereby, can realize the utilization of mine waste gas circulation simultaneously.
2. utilize wind-drive device that the air-flow of mine exhaust outlet is collected and flow to generator again, can obviously accelerate wind speed and make full use of the wind resource that mine ventilation produces.

Embodiment
The invention provides a kind of method of utilizing the useless wind of mine to carry out wind-power electricity generation, this method is utilized the power of the air-flow of mine ventilating shaft mouth discharge as wind-power electricity generation, because wind-drive device wind inlet cross section is greater than wind-drive device exhaust outlet cross section, after air-flow is collected also supercharging through wind-drive device, the place forms extremely strong air-flow at the wind-drive device exhaust outlet, flows to wind-driven generator then and sends electric energy.Described wind-drive device wind inlet section area should be not less than mine exhaust outlet section area twice.Described wind-drive device wind inlet and mine exhaust outlet are separated, and are open space, and wind-drive device wind inlet and mine exhaust outlet distance preferably are not less than 1 meter, to guarantee the normal ventilation of mine inside more fully.
Further specify technological scheme of the present invention below in conjunction with accompanying drawing:
After the air-flow that mine ventilating shaft mouth is discharged is discharged from the useless wind outlet 3 of mine, after wind-drive device intake grill 4 enters wind-drive device 5 superchargings, drive two typhoon power generators 9 by the turbine fan blade 7 of wind-drive device exhaust outlet 6 drive installations through cylindrical worm retarder 8 and send electric energy at wind-drive device exhaust outlet 6 places.
