Description
Technical field
The utility model belongs to mine ventilation environmental protection equipment, and in particular to one kind makes underground mine returnairshaft high temperature saturation wind
Stream condensation and dewfall, the dehydrating unit for avoiding producing " white smoke " phenomenon in well head.
Background technology
Mine ventilation system it is fresh it is distinguished and admirable enter from earth's surface along downcast, enclosed with down-hole mining Work machine equipment, humidity
Hot and humid area occurs for the wet source of a variety of heat such as rock wall surface, ore autoxidation so that underground air temperature gradually rises, humidity increases
Add.Usually, mine down-hole relative air humidity is close to 100% saturation state, and now mine air temperature is close to dew-point temperature,
As long as environment temperature is less than mine air temperature, the vapor in air is by condensation and dewfall.Therefore, when underground hot-air is along return air
Well well head runs into earth's surface cold air less than own temperature when discharging, the vapor in mine saturation hot-air will be cooled cold
But, condensation and dewfall, and returnairshaft air quantity is big, air velocity is high, the condensation globule are broken point in the case where the impact of high velocity air promotes
Solution flings well head into the more tiny water fog particle of particle diameter, forms the white water smoke of return air well head, can go out wellhead ground and may be up to
More than 50 rice, seem " white smoke " on the visual field, returnairshaft becomes underground " chimney ", trigger mining area nearby residents it is uneasy whole-heartedly
Reason, if especially mine is in urban fringe, brings serious visual pollution.
The most of mines in China are away from city, and many places are in mountain area knob, thus it is this " smoldering " to be directed to return air well head
Phenomenon, the country are rarely reported.But as country gradually draws to the pay attention to day by day of environmental protection, " white smoke " pollution of returnairshaft well head
The concern of people is played.
