Background technology
Along with the mankind to energy savings, tap a new source of energy and the attention of environmental protection, the thermal storage and energy accumulation technology is subjected to countries in the world and more and more payes attention to, and obtains application more and more widely.The U.S. has just begun the research of heat absorption/storage heater the sixties, and Garrett company has successively designed the space thermal device of 3kW, 10.5kW, has carried out a large amount of component capabilities experiments; The enforcement of the mid-80 U.S. freedom Space Stn. Program has greatly promoted the development of high-temperature phase change heat accumulation technology; The U.S. proposes to build up at mid-21st Century the power station, space of a 1.6kW, utilizes microwave system to pass electric power back ground again and uses, in case realize it will being the breakthrough progress that human energy technology is utilized; France was contained in the energy storage bead of developing (TSL system) in 1992 and is used for energy storage in the container, and its energy storage density is 10 times of consubstantiality ponding; The existing many companies of Japan production accumulation of heat fiber, output constantly enlarges, and also has portable hand warmer, has thrown in the Japanese market.
China electric load paddy peak is obvious, and its ratio is about 0.4～0.6, makes that electricity generation system decrease in efficiency, thermal storage and energy accumulation technology are the feasible patterns that promotes consumption of valley period power power and peak regulation, also is the technical guarantee of carrying out time-of-use tariffs.Whole nation pipe network heating system (not comprising thermo-power station) utilization efficiency of heat energy only is about 30%, and Industrial Boiler is seriously polluted.The tangible area of abundant and peak-valley difference at electric power, development thermal storage and energy accumulation technology is just extremely important, and the electric power of paddy phase is transformed into thermal energy storage in heat accumulating element, is used to add hot water and heating was used for the peak phase.The heating equipment in China cities and towns except that part by the steam power plant supply, other parts
Supply with by fire coal, oil burning boiler and electric heating, the coal and oil boiler all has pernicious gas and soot emissions, contaminated environment, common electric heater and electric heater use in peak times of power consumption often, increased the peak-valley difference of electricity consumption, if use thermal storage and energy accumulation equipment instead of part coal and oil boiler and common electrical warmer, be significant to the effect that improves environment and peak load shifting, also can effectively safeguard the safe operation of generating set simultaneously.
As seen, no matter the research and development of heat accumulation method and device thereof are now or all account for consequence in the usings energy source in future, especially can realize the peak load shifting of electric power, reduce generate output, safeguard the generator safe operation, avoid the environmental pollution of coal and oil.From present disclosed document, electric heat storage technology mainly comprises sensible heat accumulation of heat and phase-transition heat-storage.Patent 2204959[1] in announced a kind of electric heater that adopts the solid dielectric accumulation of heat, its heat storage medium adopts a kind of nonmetal solid material; Patent 86208443[2] announced that a kind of phase transformation material that adopts is the Electric heater of heat storage medium; This device relies on the crystallization of phase-change material to reach the purpose of accumulation of heat.Patent 95229702[3] announced the Electric heater that adopts the phase-change material accumulation of heat equally, this device utilizes liquid-solid phase transformation to reach electric accumulation of heat purpose.Similarly patent also has 7,8, and these patents all adopt sensible heat accumulation of heat or phase-transition heat-storage.Still do not have at present and adopt the patent of absorption accumulation of energy to occur.
In the adsorption/desorption process of adsorbent and adsorbate, be accompanied by a large amount of heat energy release/absorptions, the present invention just is based on this physical chemical phenomenon and carries out work.Adopt the compound adsorbent of the up-to-date development of this seminar, the energy storage density of material can reach 800 to 1000kJ/kg, and adopts sensible heat accumulation of heat or phase-transition heat-storage to reach the energy storage density of 200～300kJ/kg at most only.As seen, adopt the performance of absorption accumulation of energy to be better than other accumulation of energy mode.
Summary of the invention
Task of the present utility model is to provide a kind of heat of adsorption of the adsorption process with adsorbent and adsorbate to adsorb the absorption type accumulation of heat electricity heating installation of accumulation of heat, when increasing energy storage density, effectively utilize the peak valley price difference of electrical network, promote the electricity consumption in period of electrical network low ebb.
The utility model proposes the device of a kind of absorption type accumulation of heat electricity heating, structure as shown in Figure 1, it is made up of outer case 1, condenser 4, air inlet 5, air outlet 6, air channel 12, absorber 2, reservoir 9, water pump 11, adsorbent pipeline, and absorber 2 and condenser 4 and reservoir 9 are connected by pipeline.Be furnished with heat-insulation layer 3, electric boiling plate 7, radiated rib 13, capillary jet pipe 8 in the absorber 2, be full of adsorbent around electric boiling plate 7 and the radiated rib 13.Between absorber 2 and the condenser 4 valve is arranged.In the heating desorption process, the valve open between condenser 4 and the absorber 2, desorb is closed after finishing.In desorption process, the air in the air channel 12 flows through condenser 4, condensation heat is brought indoor.In adsorption process, the valve open between reservoir 9 and the absorber 2 finishes until absorption.In adsorption process, the air in the air channel flows through absorber 2, heat is taken to indoor under blower fan drives.
