Description
Technical field
The present invention relates to deep frozen soil extremely cold area pipe well water intake system, particularly a kind of deep frozen soil extremely cold area pipe well is antifreeze
Device.
Background technology
In High aititude depth frozen soil extremely cold area, permafrost layer depth is up to 40 ~ 150m, and the water intaking deep about 100 ~ 200m of pipe well is quiet
Water level about 10 ~ 20m.It is higher than the pipe well of frozen soil layer to hydrostatic level, when well pump is intermittent duty mode, after well pump stoppage in transit, by
It can not be emptied in pumping water in lifting pipe, the well water pumped in lifting pipe more than frozen soil line is caused, which to be frozen, makes well pump can not be again
Subnormal startup is drawn water.Underground water hydrostatic level works as pipe about between several meters to tens meters of below ground in the pipe well of different regions
It is low water level pipe well when underground water hydrostatic level is less than frozen soil line in well;It is high water level pipe well when hydrostatic level is higher than frozen soil line.
After well pump is stopped transport, due to the effect of pump discharge bottom valve, the water in lifting pipe will not fall emptying after rise or the emptying time is very long, in this way
Static water column is formed in pipe well, the water column being at this moment located in lifting pipe in frozen soil layer is frozen quickly.For Gao Shui
Position pipe well, ordinary water level is located within frozen soil layer in pipe well, since water temperature is higher in lifting pipe and water velocity during normal operation
It is larger to be frozen, after water pump is stopped transport, even if taking the measure of sluicing, the water level in lifting pipe also within frozen soil layer,
It is consistent with hydrostatic level in pipe well, become static water column and be frozen.
If a kind of technical solution can be provided, the antifreeze of deep frozen soil extremely cold area pipe well is solved the problems, such as, will be very intentionally
Justice.
Invention content
To solve the above problems, the present invention provides a kind of deep frozen soil extremely cold area pipe well defroster, including air compressor machine,

Further, bottom of the tube of pumping up water is provided with drain hole.
Further, described device further includes isolating valve, the isolating valve be set to air injection pipe and lifting pipe end it
Between.
Further, described device further includes check-valves, and the check-valves is set between air injection pipe and isolating valve
Beneficial effects of the present invention are:
(1)Tradition is antifreeze to set electric-heating belt using well bore wall, but the deep frozen soil extremely cold area of temperature -30 ~ 40 degree is needed
Accompanying-heat cable calorific value is very big, and energy consumption is high, substantially inapplicable.The present invention is maintained using gas injection defroster by air pressure tank
Pipeline air pressure, simple system are stablized, and low energy consumption, improves the reliability of winterization system.
(2)Traditional electric tracer heating system needs just be designed type selecting, and during operation after obtaining outside air temperature variation range
Such as the extreme weather of super scope of design, electric tracing will fail.The present invention is applied widely, and no matter ambient temperature changes, and raises
Water pipe will not freeze.

Specific embodiment
The present invention design concept be:A kind of deep frozen soil extremely cold area pipe well defroster is provided, resolving ideas is in water
After pump shutdown, as long as emptying the water within frozen soil layer in lifting pipe solves frozen problem.
As shown in Figure 1, including air compressor machine 1, air pressure tank 2, water tank 3, air injection pipe 4, check-valves 5, isolating valve 6, shut-off valve 7,
Pipe well 8, lifting pipe 9, immersible pump 10, blowdown pipe 11, drain hole 12.
The connection relation of various pieces is:The air compressor machine 1 is connect by blowdown pipe 11 with 2 entrance of air pressure tank, check-valves
5th, isolating valve 6 is sequentially arranged between the end of air injection pipe 4 and lifting pipe 9, and the outlet of air pressure tank 2 passes through air injection pipe 4 and lifting pipe 9
Part unicom near end, shut-off valve 7 are set to lifting pipe 9 and water tank junction.9 initiating terminal of lifting pipe extend into pipe well 8
It is interior, initiating terminal connection immersible pump 10.9 bottom of lifting pipe is provided with drain hole 12.
Preferably, in order to ensure safety, the reliability of the system is maintained, air compressor machine 1 sets two, and one spare.Two
The outlet of person is all connected to 2 entrance of air pressure tank.
It should be appreciated that isolating valve 6, the setting of check-valves 5 are a kind of preferred embodiments, when there is method for distinguishing that can achieve the goal
When, it can be not provided with, directly connect air injection pipe 4 with lifting pipe 9.
The effect of each section is illustrated below:
Air compressor machine 1:For providing compressed gas source for the present invention.
Air pressure tank 2:Pressure is kept for gas injection system, the system pressure is maintained to balance.
Water tank 3:For storing the well water extracted from pipe well.
Air injection pipe 4:For connecting air pressure tank 2 and lifting pipe 9, and high pressure gas is injected in lifting pipe.
