Description
Technical field
The invention discloses a kind of fused salt electric heat storage boilers more particularly to abandonment to abandon light and the electrically heated fused salt electric heat storage of paddy
Boiler belongs to fused salt heat storage technology field.
Background technique
As gap is increasing round the clock for society's electricity consumption structure, the demand of peak load shifting is more strong；It is supplied using trough-electricity
Warm, cooling supply attracts attention for the fused salt hold over system of steam.
Fused salt thermal storage and energy accumulation is at present a new technology in China, is mostly derived from external solar light-heat power-generation technology,
Two kinds of spot modes that the country introduces have, at present also all in experimental verification.Other process flows or base for energy storage
Originally external fused salt application mode is continued to use, the heating energy storage of fused salt, heat exchange structure are sufficiently complex；Just come for molten salt energy-storage heating
It says, domestic several companies are exchanged heat using high temperature melting salt cellar, low-temperature molten salt tank, fused salt pump circulation, pipe insulation heat tracing, high temperature, is low
Then temperature heat exchange just can provide hot water to hot duct.Fused salt heating；By pump for liquid salts by low-temperature molten salt liquid, pass through fused salt
Electric heater is recycled to the storage of high temperature melting salt cellar, and the fused salt liquid of high temperature melting salt cellar is extracted out by pump for liquid salts when heat exchange uses, is logical
It crosses fused salt/conduction oil exchanger, again by conduction oil/water coke slurry device heating water, is provided to heating user and uses, pass through exchange
The fused salt liquid of device cooling flows back to low-temperature molten salt tank by pipeline.Since secondary heat exchange, the thermal efficiency cannot make full use of, due to dividing
It is big from heating, pipeline, thermal loss, and equipment is considerably complicated, entire heating heat exchange process is difficult to control, high-temperature molten salt
Liquid circulation to equipment, pipeline, material requirements is quite high and there are security risks the disadvantages of.And entirely the circulatory system is necessary
Heat tracing is carried out, when tracing system stopping, pipeline valve temperature are lower than fused salt freezing point, fused salt liquid can be solidified, be caused
The entire circulatory system is scrapped, and huge loss is generated.And since heat tracing consumes the energy, high-temperature molten salt circulated heat scatters and disappears, makes
At fused salt thermal storage and energy accumulation ineffective systems, complicated heating heat-exchange system, which is no different, considerably increases infrastructure investment cost.
In the prior art, extensive use has been obtained because it is with good cost performance in fused salt accumulation of heat.It is currently used
Hot and cold fused salt is separately stored in different tank bodies in double tank fused salt accumulation of heats, and the temperature of molten salt for participating in heat exchange is constant, is conducive to stablize
Power generation high-quality steam is exported, but double tank design costs are higher, circulation line is more, therefore its energy loss is more, fused salt
Easily solidification causes system high risk, is not suitable in small-sized heating system.In consideration of it, how to provide, a kind of structure is simple, cost
For the cheap, thermal efficiency using high, energy peak load shifting, the fused salt electric heat storage boiler to be worked using valley period power power is art technology
Personnel's technical issues that need to address.
Summary of the invention
The purpose of the present invention is to provide a kind of integrated fused salt electric heat storage boilers, and traditional fused salt electric heat storage system phase
