Description
Technical field
The present invention relates to phase-transition heat-storage energy-saving fields, more particularly, to a kind of phase-transition heat-storage heating installation.
Background technique
The problems such as world today's energy largely consumes, resource exhaustion, environmental pollution take place frequently remind us constantly it is noted that
Power saving, various countries turn to research direction on new energy development, such as wind energy, solar energy etc., but but go out using upper
Problem, intermittent and unstability are its maximum problem, this declines utilization efficiency, how it to be made to become stabilization energy
Source output is the emphasis of its research.The application of new energy can be generated in power generation process mainly in power generation direction at present
A little unstable thermal energy, if it is possible to which it is very considerable that these thermal energy, which are collected utilization,.The heat being collected into can be used for
Some industry, enterprise and household water are heated, such as the heating of heating water.
The heating method of the hot water supply equipment of current most of factory and the heating system in northern winter all with
Coal is main energy source.Coal in China reserves are big, but to the demand of coal also in cumulative year after year, coal be it is non-can be again
Production-goods source, so consumption future will face very poverty-stricken situation；And contain a large amount of sulphur and nitrogen in coal, in combustion process
A large amount of sulfur dioxide and nitrogen oxides can be generated, the two is to cause the main source of acid rain, in addition to this can also generate two
The substances such as carbonoxide, dust cause huge harm to environment.
Existing hold over system common problem is that regenerator temperature is not high, the main reason is that the selection due to accumulation of heat working medium limits
Regenerator temperature is made, hold over system is mostly that heat exchanger is directly contacted with heat-storing material at present, such as oil heater, work side
Formula is to install electrothermal tube in the cavity, fills conduction oil around heat conducting pipe in the cavity, powers on rear conduction oil and be heated
And rear heating tube road.But its problem is that preheating time is long and heat conduction amount is few, causes mass energy to be wasted and required temperature is not achieved
Degree, and does not have Insulation after use, most of heat loss can be made to waste, if conduction oil reveal accidentally there is also
Great security risk.There are also the heat-transfer working mediums of some hold over systems to select some inorganic fused salts, although ensure that heat transfer property,
But the very big problem of inorganic fused salt be when heat-transfer working medium and heat exchanging pipe are contacted due to its corrosivity compared with
By force, conduit failure and then polluted-water be will cause.
In conclusion for existing apparatus and the defect of technology, it is accordingly required in particular to a kind of New-type phase change heat accumulating and heating device, with
Solve the problems, such as exist.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind to have heating, stores
