Description

The outer blowdown wind controlling device of underground mine returnairshaft
Technical field
The utility model belongs to mine ventilation environmental technology field, and in particular to a kind of outer blowdown wind of underground mine returnairshaft Controlling device, can effectively reduce the outer blowdown wind dust concentration of underground mine returnairshaft, it is to avoid it is existing to produce " white smoke " in well head As.
Background technology
With the quickening of national Urbanization Construction paces, the urban area in domestic nearly all city is obtained in recent years Rapid expansion, the part mine that suburb is located in originally is progressively surrounded by urban district, occurs in that " city chats " phenomenon, and mining area periphery occurs Residential quarter, school and hospital.Underground mining mine returnairshaft, major function is exactly by underground high temperature, high humidity, dust-laden waste air Earth's surface is discharged, autumn and winter earth's surface temperature is relatively low, underground high temperature, high humidity waste air discharge well head and earth's surface cold air meet and reached " guttation " condensation forms that wind speed in white haze, returnairshaft is higher after saturation state, and typically in 10~15m/s or so, waste air can be rushed Go out that more than well head 20~30m is high, formed on returnairshaft well head top 20~30m it is high be similar to chimney-like white haze, cause ore deposit The worry of area's surrounding resident and the concern of environmental administration, if especially mine is in urban fringe, bring serious regard Feel pollution.
Country pays much attention to environmental protection, and environmental problem has right of veto by one vote, can not such as realize that returnairshaft waste air is up to standard Discharge, eliminates returnairshaft autumn and winter well head fog, bargh will face environmental administration's significant fine, or even close down problem.
The content of the invention
The well head " white smoke " that the purpose of this utility model is formed aiming at mine returnairshaft high temperature saturated air is regarded Feel that there is provided blowdown wind controlling device outside a kind of underground mine returnairshaft for contamination phenomenon.The device collection returnairshaft demisting and depositing dust work( It can be integrated, the outer blowdown wind dust concentration of returnairshaft can either be effectively reduced, dust qualified discharge is realized, can effectively reduce again Returnairshaft well head white haze concentration.
To realize above-mentioned purpose of the present utility model, the outer blowdown wind controlling device of the utility model underground mine returnairshaft with Lower technical scheme:
The outer blowdown wind controlling device of the utility model underground mine returnairshaft is by water supply spray dust-arrest cooling mechanism, earth's surface Wind guide channel, pressure wind heat sink and demister are combined:
