Description
Technical field
This utility model relates to mine correlative technology field, particularly a kind of mine return air heating system.
Background technology
In progress of coal mining, for getting rid of the harmful gass such as the gas that produces in mine coal seam and country rock recovery process,
It is passed through fresh air, regulation down-hole climatic environment, it is ensured that mine safety production to underground work place, mine need to be led to
Wind.For ensureing that ventilating system is stable, " safety regulations in coal mine " regulation mine ventilation should use force ventilation, chief ventilators adopt
It is aerated by pull-out type or forced ventilation mode.The outlet that so mine is at least two, a responsible air intake of outlet,
One entrance is responsible for return air.
Winter is the lowest due to winter temperature, and the mine inlet temperature in the north is the lowest, causes pit shaft to freeze, affects mine safety
Produce.For preventing pit shaft from freezing, it is ensured that shaft production is normally carried out, mine air intake need to be heated, " safety regulations in coal mine "
Regulation down-hole temperature is minimum must not be less than 2 DEG C.
Prior art:
Current pit shaft mode of heating typically uses coal-burning boiler to heat, and so will burn a large amount of coal, and boiler exhaust gas is also
Environment is produced and pollutes.
In the last few years, have also appeared and utilize heat pump techniques that mine air intake is heated.Due to mine air intake and return air away from
Close to general, and mine air is in the flow process of down-hole, due to the heat given out by roadway surrounding rock and mined
Coal etc. heat, and during distinguished and admirable arrival return air pit shaft, temperature typically at 15 DEG C and long-term substantially constant, just contains in such return
Substantial amounts of heat, utilizes these heats that Intake shaft heating just seemed pole is necessary.
Heat pump techniques just can be used for low-temperature heat source and recycles, and its system principle is general as shown in Figure 1:
1, mine return air recycling waste heat is absorbed.The chief ventilators exhaust outlet 2 ' of mine return air well 1 ' installs heat exchanger
3 ', heat exchanger 3 ' pass to carry energy working medium such as water by the heat of mine return air, load working medium can be heated to about 10 DEG C.Carry energy
Working medium drives the vaporizer of arrival heat pump 6 ' by circulation line 4 ' by delivery pump 5 ', by the heat exchange vaporizer to heat pump 6 '
Coolant heats.Heat exchange rear bearing energy Temperature of Working drops to about 2 DEG C, is recycled back into the exhaust outlet 2 ' of mine return air well 1 '
Absorb return air used heat.
2, the coolant internal circulation system in heat pump 6 '.Coolant has absorbed heat and has arrived condenser side by heat pump compression, logical
Cross the load energy working medium of heat exchange air inlet system to about 40 DEG C.
3, air intake heating circulation system.Arrival is driven by circulation line by delivery pump 7 ' by the load energy working medium of heat pump
Mine air intake well head, transfers heat to mine downcast 9 ' by being arranged on the heat exchanger 8 ' of air intake well house, thus realizes
Effect to the heating of mine air intake.Carry and drop to 2～4 DEG C at temperature after energy working medium transfers heat to air intake, be recycled back into
Heat pump condenser side absorbs heat.
But, there are the following problems for prior art:
1, system complex, output investment ratio is relatively big, and maintenance cost is high, need to install heat pump additional and carry out repeatedly heat exchange.General next
Saying, heat pump need at least carry out four heat exchange, and this is accomplished by setting up three blood circulation.
2, the power consumption of heat pump own is bigger, and energy value is much larger than the coal with calorific value, and operating cost is high, as system is tieed up
Protect not in place or operating mode is unreasonable, it is likely that be more expensive than boiler.By equivalent value calculate, the efficiency ideal situation of heat pump next
As at about 3 times, i.e. consume 1 degree electric energy and export 3 degree of electric heats；As the value calculation such as pressed, due to power plants generating electricity efficiency of being heated
Limiting, 10,000 degree of electricity are about equivalent to 3.5 tons of standard coals, differ greatly with 1.229 tons of standard coals of equivalent value, it is possible to the most energy-conservation.
3, due to electric energy the carbon emission factor much larger than fire coal, even if in the case of heat pump rationally runs, also without
Method realizes enterprise's carbon emission amount and declines.
4, due to mine air intake heating-up temperature require low, heat pump absorb low temperature heat energy and be converted into middle warm can
Have little significance.For preventing water freezing and improving heat exchange efficiency consideration, the load energy working medium having absorbed heat from returnairshaft is inhaled by heat pump
After receiving heat, temperature is typically not less than 2 DEG C.For improving heat exchange efficiency and preventing from freezing, load energy working medium is after downcast heat release, warm
Degree general control is between 2～4 DEG C.So load energy working medium is after downcast heat release, owing to temperature is the lowest, can bypass heat pump, directly
Receiving returnairshaft and absorb heat, it is the most little to there is meaning in heat pump.
