Description
Technical field
The utility model relates to a kind of liquid of the three dimensional intersection formula heat exchange of heat-exchanger rig, especially stereochemical structure-gas to be situated between
Matter stores heat exchange structure.
Background technique
World economyIt is quickDevelopmentIt needs moreThe energy, andFossil energyShortage promote countries in the world will developIt can The renewable sources of energyAsStrategyProperty new industry is placed in the status first developed.Energy storageAsThe energyThe important link utilized, to work
Industry energy conservation and renewable energy utilization have especially important effect.Scale renewable energy heat utilization is following China's energy
Development priority, but intermittence and the defect of supply cannot be stablized since renewable energy county has, not be able to satisfy the big rule of industrialization
The requirement that mould continuously energizes, and energy consumption of industry is maximum terminal energy consumer sector, China, Zhan Quanguo total energy consumption
Specific gravity maintains always 70% or so.Primary energy utilization ratio is significantly less than advanced country, and one of the main reasons is intermittent Gao Pin
Matter waste heat is not utilized effectively, it is therefore necessary to develop high-efficiency thermal storage technology, to improve using energy sourceEfficiency。
Heat-storing material is exactly a kind of new chemical material that can store thermal energy.It is in specific temperature (such as Xiang Bianwen
Degree) biological phase change is issued, and along with absorbing or releasing heat, can be used to the temperature for controlling ambient enviroment, or to store
Thermal energy.It stores heat or cooling capacity, it is released again when needed, to improveThe energyUtilization rate.
The course of work of heat-storing material includes two stages: first is that the storage stage of heat, i.e., extra dynamic in peak period
Power, industrial exhaust heat waste heat or solar energy etc. are stored by heat-storing material；Second is that the release stage of heat, i.e., when in use
Heat is released by heat-storing material, for heating, heat supply etc..Heat storage and release step cycle carry out, so that it may utilize
Heat-storing material solves the incoordination of thermal energy over time and space, reaches high efficiency of energy and utilizes and energy-efficient purpose.
Divide by heat storage type, heat-storing material can be divided into four classes: sensible heat heat-storing material, phase change heat storage material, heat chemistry
Heat-storing material and adsorptive heat-storage material.
1, sensible heat heat-storing material
Sensible heat heat-storing material is the storage that heat is carried out using the change procedure of substance self-temperature, straight due to can be used
Contact heat exchange or fluid inherently heat storage medium are connect, thus storage, exothermic process are relatively simple, are to apply early stage
More heat-storing material.The sensible heat heat storage technology also comparative maturity the simplest in all heat-storing materials.
Sensible heat heat-storing material can largely be directly obtained from nature, cheap and easy to get.Sensible heat heat-storing material be divided into liquid and
Solid two types, fluent material is common such as water, solid material such as rock, cobblestone, soil etc., wherein there is several sensible heats
Heat-storing material is noticeable, such as the mixing material of Li2O and Al2O3, TiO2 high temperature sinter molding.
Since sensible heat heat-storing material is to carry out heat storage by the temperature change of heat-storing material, exothermic process is not
Energy constant temperature, thermal storage density is small, causes the bulky of thermal storage equipment, and heat storage efficiency is not high, and there is temperature with ambient enviroment
Difference will cause thermal loss, and heat is unable to long term storage, is not suitable for long-time, large capacity accumulation of heat, limits sensible heat heat-storing material
Further development.
2, phase change heat storage material
Phase change heat storage material is to be sent out using substance in phase transformation (such as solidification/fusing, condensation/vaporization, solidification/distillation) process
The raw heat of transformation carries out the storage and utilization of heat.
Compared with sensible heat heat-storing material, phase change heat storage material thermal storage density is high, can be released at a constant temperature by phase transformation big
Calorimetric amount.Although the latent heat of phase change value that one liquid of gas gentle one changes admittedly it is more solid than liquid one transformation, consolidate change when latent heat
Greatly, but because its in phase transition process there are the great variety of volume, make it that can there is very big difficulty in practical implementation.
According to phase transition temperature height, latent-heat storage can be divided into low temperature and two kinds of high temperature, and low temperature latent-heat storage is mainly used for Waste Heat Recovery, too
Sun can store and heat supply and air-conditioning system.High-temperature phase change heat accumulation material mainly has high temperature melting salt, mixing salt, metal
And alloy etc., it is mainly used for aerospace etc..Common latent heat storage material has calcium chloride hexahydrate, Sodium acetate trihydrate, organic
Alcohol etc..
Latent-heat storage mode has thermal storage density higher (can generally reach 200kJ/kg or more), stores, exothermic process
The advantages that approximate isothermal, process is easy to control, therefore phase change heat storage material is the mainstream of current heat-storing material research and application.
3, heat chemistry heat-storing material
Heat chemistry heat-storing material mostly carries out accumulation of heat using metal hydride and amic reversible chemical reaction, is there is catalysis
Thermal response speed is fast when agent, temperature height and separate equilibrium state.It is external to react the experiment for carrying out solar energy and storing heat power generation using this
The problems such as studying, but emphasis needed to consider the tightness of storage container and system, and generating corrosion of the gas to material.
Heat chemistry heat-storing material has many advantages, such as thermal storage density height and cleaning, pollution-free, but reaction process is complicated, technology
Difficulty is high, and requires height to device security, and one-time investment is big, still has relatively large distance with practical engineering application.
4, adsorptive heat-storage material
Absorption refers to fluid phase (gas or liquid containing one or more components) and has porous solid particle phase
When contact, sorption or withholding process of the solid particle (i.e. adsorbent) to adsorbate.It is non-uniform because of adsorbent solids surface
Property, the conversion effet of energy, referred to as heat of adsorption are generated along with adsorption process.In adsorption/desorption circulation, heat can be passed through
Storage, release process are come the purpose of changing the grade of heat and use the time, realize refrigeration, heat supply and accumulation of heat.
Adsorptive heat-storage is a kind of novel heat storage technology, and it is using absorption working pair come to adsorption/desorption that research, which is started late,
The storage and conversion of heat are carried out in cyclic process with the fuel factor occurred.The thermal storage density of adsorptive heat-storage material may be up to
800~1000kJ/kg has many advantages, such as thermal storage density height, the loss of heat-accumulating process empty calory.Due to adsorptive heat-storage material non-toxic
It is pollution-free, it is another research hotspot in addition to phase change heat storage material, but since adsorptive heat-storage material is usually porous material, passes
Hot mass transfer performance is poor, and adsorptive heat-storage is complex, is that primary study solves the problems, such as.
Which kind of heat-storing material no matter is taken, how will efficiently the heat stored be needed to be transmitted in heat-storing material and stored up
It deposits, and it is the key that heat storage technology application that heat in heat-storing material, which is conducted again in the environment for being discharged into and need heat,；Therefore it is existing
There is the heat-exchanger rig of technology, regenerative heat exchange is inefficient, needs to be continuously improved regenerative heat exchange efficiency, optimization structure is just able to satisfy
Actual needs.
