Description
Technical field
The utility model belong to mine air cooling with dedusting technology field, more particularly to a kind of mine air cooling and
Dust pelletizing system.
Background technique
Dust and high temperature are two kinds of main harms in mine down-hole production.In Mine Production, as drilling,
The links such as explosive blasting, development machine and coal mining machine operation, roof control, the loading of coal and transport can all generate largely
Dust.Dust has explosion, causes damages to the respiratory apparatus of human body.The side of spray sprinkler is mainly used in mine at present
Formula carries out depositing dust.High-pressure water mist is melted into subtle water droplet injection in air by nozzle, the wet sinking of floating dust, and makes it
Wet bonding is not easy to fly upward, while is attracted to the dust laden air of surrounding in water mist.The mode of spray sprinkler is in mining work
Face is widely used.
Each main coal mining country, the world subsequently enters deep mining, and coal mining depth-averaged is with the speed in 8-16 meters/year
Increasing.China had 40% or so mine to enter or close to the deep mining stage, had nearly hundred metal mine mining depths to be more than
1000 m.With being stepped up for mining depth, mine ground temperature is also increased.It unites according to China coalfield ground temperature measurement relevant information
Meter, hundred meters of geothermal gradients are 3 DEG C/100m.When getting working face temperature meets or exceeds 26 DEG C or rock temperature meets or exceeds 30 DEG C
Mine, belong to high-temperature mine；When mining depth is more than 650m and temperature is more than 26 DEG C, belong to hot deep mine.Primitive rock temperature
Area higher than 31 DEG C is known as the area level-one Re Hai, and area of the primitive rock temperature higher than 37 DEG C is known as the area second level Re Hai.In mine, such as
The heat that fruit worker generates in labour cannot distribute, and body temperature will rise, and generate the symptoms such as dizziness, collapse, heatstroke, threaten
Practitioner's health and life security.Therefore, regulation in China " safety regulations in coal mine ", when getting working face air themperature
More than 26 DEG C, when electromechanical equipment chamber is more than 30 DEG C, it is necessary to shorten the working time of overtemperature work site personnel.When digging work
When the air themperature for making face is more than 30 DEG C, electromechanical equipment chamber is more than 34 DEG C, it is necessary to stop operation.For there is the mine of heat evil must
Cooling measure must be taken.The area level-one Re Hai cools down frequently with the modes such as ventilation quantity are increased, and is higher than 37 for primitive rock temperature
DEG C mine cooled down by the way of ventilation and often met due to mining machinery, rock heat, hot water radiator etc.
The not requirement of environment temperature, it is necessary to use mechanical refrigeration cooling measure.In mechanical refrigeration system, the air cooler of air is handled
Two classes are broadly divided into, are surface-type air device and spray chamber respectively.Surface-type air cooler makes chilled water by surface-type heat exchanger
To reduce air themperature be common type in mine with air indirect heat exchange, but exist and involve great expense, heat exchange efficiency compared with
Low, the disadvantages of weight is larger.And spray chamber is then that chilled water directly carries out hot and humid area with hot-air, heat exchange efficiency is higher, phase
With needed under cooling capacity freezing water it is small, while compare surface-type air cooler, also have metal material consumption it is small, light-weight, ventilation resistance
Power is small, blower small power consumption and the advantages that low cost.But spray chamber is not answered well in down-hole cooling system
With.Because using spray chamber as end air cooling equipment, chilled water system is open system, if guaranteeing chilled water system
It operates normally, chilled water pump is necessarily placed on the return pipe of spray chamber, for being located at multiple working faces, multiple of different depth
The type pit cooling system of spray chamber needs the more chilled water pumps that working face is arranged in, it cannot be guaranteed that the safety of chilled water system
Stable operation.Therefore, if type pit cooling system is combined with the dust prevention system of getting working face, by returning for cooling system spray chamber
Water is used for nearest getting working face dust-proof water, and the return water of spray chamber is sprayed onto working face sky through getting working face dust prevention system
Between, while playing dustproof effect, the cooling capacity in chilled water can be also made full use of, certain cooling is generated to working face air
Effect.
