It is connected to for the first air duct 15 with the second air duct 16, third air duct 17 is connected to the 4th air duct 18, therefore the present invention is in the first air duct 15
With inside third air duct 17 be equipped with axial flow blower 14, for providing air-flow mobilization dynamic.Alternatively, in the second air duct 16 and the 4th wind
Axial flow blower 14 is equipped with inside road 18, for providing air-flow mobilization dynamic.In other alternate embodiments, as needed,
It can be all provided with axial flow blower 14 inside four above-mentioned air ducts, i.e., in the first air duct 15, the second air duct 16,17 and of third air duct
It is equipped with axial flow blower 14 in 4th air duct 18, so as to improve wind speed, accelerates heat exchange efficiency.
Preferably, no matter in winter or the summer axial flow blower 14 is explosion-proof Bidirectional axial flow fan, is arranged such, it can be ensured that
In season, when needing the flow direction of fresh air and return air to change, only need to change 14 direction of rotation of axial flow blower can be realized change of the wind.
Existing heat exchange of heat pipe is roughly divided into monoblock type and separate type.Separate type heat pipe exchanger be suitable for downcast and
Returnairshaft position farther out the case where, for downcast and returnairshaft are apart from farther away mining area, if using integrated thermal
Return air is transported near new ventilating shaft by heat exchanger, undoubtedly needs to be laid with longer transport air duct, not only increases the investment of equipment, and
And mining area pipeline can be made more complicated；Meanwhile during transportation, there will necessarily be the loss of thermal energy, reduce recovering effect.
The air inlet and returnairshaft of well wind afterheat utilizing system provided by the invention are closer, and are predominantly carried out between gas and gas
Heat exchange, therefore the present invention use integral heat-tube heat exchanger, i.e., heat exchanger 5 use monoblock type gravity assisted heat pipe heat-exchange unit.
Fresh air (air inlet) to guarantee that return air and summer that either winter uses as heat source are used as cold source can
Its effect is kept, in return air air inlet duct 1, return air exhausting duct 2, fresh air air inlet duct 3, fresh air exhausting duct 4, the first air duct 15, second
The outside wall surface in air duct 16, third air duct 17 and the 4th air duct 18 is provided with insulating layer.Preferably, insulating layer is rock wool layer, rubber
Mould layer or polyurethane foaming layer.
Further, to guarantee insulating layer service life, matcoveredn is set in the outside of insulating layer.Preferably, it protects
Layer is galvanized sheet, aluminium alloy plate or color steel plate.
In conclusion well wind afterheat utilizing system provided by the present application is utilized simultaneously by being designed to air duct arrangement
Gravity type heat pipe heat exchanger in winter recycles waste heat in underground return air, preheats Intake shaft；In summer, by valve
Return air is used as cold source, reaches cooling Intake shaft, reduce the effect of heat evil by door conversion.
In the following, being further elaborated in conjunction with specific embodiments to the well wind afterheat utilizing system of the application:
In, return air temperature, new air temperature are determined according to regional environment temperature and extreme minimum temperature, are to become
Change, the standard that usually reach 2 DEG C~4 DEG C by the air inlet wellhead temperature after heat exchange to guarantee wellhead anti-freezing.
When winter needing to carry out heating heating to fresh air outside well using return air in well, it is corresponding to adjust return air air inlet duct 1
Third valve 8 open, the first valve 6 close, adjust corresponding 4th valve 9 in return air exhaust passage 2 open, the second valve 7 close
It closes.Accordingly, the unlatching of corresponding 5th valve 10 of fresh air air inlet duct 3 is adjusted, the 7th valve 12 is closed, adjusting fresh air exhaust passage 4
Corresponding 6th valve 11 is opened, and the 8th valve 13 is closed.
At this point, return air glide path are as follows: 17-heat exchanger of return air air inlet duct 1-third, 8-third of valve air duct 5-the four
Four 9-return air of the valve exhaust passage 2 of air duct 18-the.Fresh air glide path are as follows: fresh air air inlet duct the 10-the second wind of the 3-the five valve
The 5-the first air duct of 16-heat exchanger of road 15-the six 11-fresh air of valve exhaust passage 4.Return air is when flowing through heat exchanger 5 with certain
Wind speed laterally skim over the evaporator section (5 lower end of heat exchanger as shown in figure 1) of heat exchanger 5, the work in 5 liquid pool of heat exchanger (i.e. evaporator section)
Make heated liquid evaporation, the colder condensation segment of heat pipe that steam flows upwardly into heat exchanger 5 under pressure difference effect (changes as shown in figure 1
Hot 5 upper end of device), releasing temperature after latent heat of vaporization return air releases the latent heat of vaporization reduces, and enters return air air draft along the 4th air duct 18
Road 2, is ultimately discharged into atmosphere or the heat source as other way continues to use.At the same time, outdoor fresh air (cold air) is flowing
When the colder condensation segment of heat pipe (5 upper end of heat exchanger as shown in figure 1) through heat exchanger 5, the latent heat of vaporization is absorbed, preheating purpose is reached；
New air temperature after heating is increased to predetermined temperature or more, enters fresh air exhausting duct 4 along the first air duct 15, is ultimately delivered to enter the wind
In pit shaft；The condensed working fluid of heat exchanger 5 under gravity, flows back into the liquid pool of evaporator section.Above-mentioned mistake
As long as journey has heating source, this process will recycle progress.
When summer needing to cool down to return air in well using fresh air outside well, return air air inlet duct 1 corresponding the is adjusted
Three valves 8 are closed, the first valve 6 is opened, and are adjusted corresponding 4th valve 9 in return air exhaust passage 2 and are closed, the second valve 7 is opened.It is right
Ying Di adjusts the closing of corresponding 5th valve 10 of fresh air air inlet duct 3, the unlatching of the 7th valve 12, it is corresponding to adjust fresh air exhaust passage 4
6th valve 11 is closed, and the 8th valve 13 is opened.
At this point, return air glide path are as follows: 15-heat exchanger of the 6-the first air duct of the 1-the first valve of return air air inlet duct 5-the second
Air duct 7-return air of the 16-the second valve exhaust passage 2.Fresh air glide path are as follows: fresh air air inlet duct the 12-the four wind of the 3-the seven valve
Road 18-heat exchanger, 5-third air duct 17-the eight 13-fresh air of valve exhaust passage 4.Because summer is non-heating season section, new wind-warm syndrome
Degree is higher, contains a large amount of low temperature heat energies；On the contrary, return side temperature is lower, the heat of fresh air is can absorb to reach cooling fresh air
Purpose, i.e. fresh air flow through after heat exchanger 5 is located at the evaporator section of lower end, carry out heat exchange with the working fluid in evaporator section, make it
By thermal evaporation, steam flows upwardly into the condensation segment (5 upper end of heat exchanger as shown in figure 1) of heat exchanger 5 under pressure difference effect, releases vapour
Change latent heat, is flowed through after heat exchanger 5 is located at the condensation segment of upper end conducive to return air, by fresh air by the steaming positioned at lower end of heat exchanger 5
The latent heat of vaporization released when sending out section absorbs, so that new air temperature is minimized, the fresh air after then cooling down is arranged by fresh air
Air duct enters in Intake shaft, to realize the purpose of cooling air inlet air duct.
Underground return air and fresh air (i.e. pit shaft air inlet) are incorporated in one simultaneously by well wind afterheat utilizing system provided by the invention
It rises and carries out heat exchange, respectively reach preheating, cooling Intake shaft effect in winter or summer.
The above description is only a preferred embodiment of the present invention, is not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.All within the spirits and principles of the present invention, it is made it is any modification,
Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
