Technical field
The present invention relates to the attemperator of thermal storage tank a kind of more particularly to a kind of insulation covers.
Background technology
With the gradually promotion and popularization of the renewable energy utilizations technology such as solar energy, wind energy, future source of energy system is by face
Face two big contradictions and challenge：First, the contradiction between the unstability and the stability of energy demand of regenerative resource supply；Two
It is solar energy resources and the unmatched contradiction of energy demand season distribution.Above-mentioned contradiction is solved, is coped with challenges, needs to send out energetically
Open up energy accumulating technique.The heat storage technology having attracted much attention in the world in recent years is big volume pond heat storage technology.As sensible heat heat accumulation skill
Art, big volume pond heat storage technology store thermal energy by promoting the temperature in for example artificial pond of water body.Thermal storage tank places mostly
In underground or semi-underground, the bottom of heat storage, side it is all or part of all in below ground, directly connect with soil
It touches.Big volume pond accumulation of heat has low cost, the scale of construction big（Up to GWh grades）, store rate of heat release it is fast, heat loss coefficient is low, can be across season
The advantage of thermal energy storage, in combination with multiple renewable energy sources skills such as solar energy optical-thermal, wind-powered electricity generation, photoelectricity, heat pump, cogeneration units

Big volume pond heat storage technology is derived from Northern Europe Denmark, early in nineteen eighty-three Denmark University of Science and Technology（Technical
University of Denmark）First 500 cubic metres of thermal storage tank in the world have been built, the first-hand of preciousness is achieved
Experimental data.In recent years, large capacity pond heat storage technology gradually moves to maturity, and 5 large-scale storages have been built up successively in Denmark
Hot-tub, and commercialized running, heat storage volume is between 60,000-200,000 cubic metres（Fan Jianhua,
JunpengHuang, Ola Lie Andersen, Simon Furbo, Thermal performance analysis of
A solar heating plant, Proceedings of Solar World Congress, 2017, Abu Dhabi,
UAE）.

So that top flexible barrier layers 4 are close to insulating layer 3 under pressure.On the one hand the flexible resistance in top can be avoided under high wind weather
Interlayer 4 is raised by high wind；External pressure is swelled prevented also from the deformation of flexible barrier layers 4 itself simultaneously, and rainwater is avoided to hoard.
Several check valves and at least two straight-through valves are arranged in top flexible barrier layers 4, wherein at least one, which leads directly to valve position, fixes, until
A few straight-through valve position is indefinite, by the way that periodically mobile straight-through valve position, extraneous air under the action of negative pressure, replace heat preservation in turn
Layer in high temperature, high humidity air improve the heat-insulating property of thermal insulation material to control air humidity in insulating layer, slow down thermal insulating material
The aging of material.A kind of preferred scheme is as shown in Figure 3.Two straight-through valves 12 are at least set on the periphery of thermal storage tank, wherein extremely
A few straight-through valve 12 is connect with suction pump 13.At least one straight-through valve 12 is not fixed position.A kind of optional scheme is straight-through
Valve 12 such as clockwise or counterclockwise, gradually replaces check valve 11 in turn according to certain orientation.As shown in figure 3, straight-through valve
12 in the direction of the clock, by the positions #1, at the subsequent positions #2, at the positions #3 ..., the last positions #N, replaces in turn one by one
Change check valve 11.Complete one wheel and then by the positions #1 a new round cycle.The time replaced between above-mentioned different location
Interval can be between 1 week and several moons.The purpose of the program is to ensure that entire insulating layer is adequately divulged information, and is avoided the occurrence of dead
Angle.Because insulation cover air temperature is high, absolute humidity is big, and atmospheric temperature is relatively low, and absolute humidity is small, is changed by above-mentioned ventilation
Gas scheme, temperature is relatively low in air, and the small cold dry air of absolute humidity flows into insulating layer 3, and temperature is higher in insulating layer 3, humidity
Larger damp-heat air is sucked discharge, and the effect of formation is that humidity reduces in insulating layer, and temperature reduces, but because of ventiduct roadbed
It is relatively small, caused by the additional heat loss of insulating layer it is also relatively small.
It will be recognized by those skilled in the art, can be to above-mentioned under the premise of without departing from protection scope of the present invention
Embodiment is carry out various modifications, changes and is combined, and thinks that this modification, variation and combination are the models in originality thought
Within enclosing.
