Using fused salt heat release, reduction takes hot electricity consumption, the expenditure that electricity takes heat is reduced using peak, paddy price difference, while being conducive to the flat peak of power network.
Because current heat is extremely all that, using water as carrier, the heat accumulation heat release interval progress of fused salt is just meaningful, and each cycle melts with hot junction
Salt is identical with the temperature of fused salt through molten salt furnace (tank) heat exchanging liquid circulation pipe internal surface with the heat exchange initial period of water, is in
Liquid is not vaporized at this temperature under the condition of high temperature (being generally near 600 DEG C) rare normal temperature, 100 DEG C of the boiling point of water, such as
Water passes through in such high temperature section, meeting instant vaporization, while making the interface drastically cool, there is destruction in the pipe wall
Internal stress, occurs what explosion was not avoided in such cases.For the safe operation of fused salt heat exchanging device, generally from low melting point
Fused salt is heated to lower temperature, or introduces high boiling substance (such as mineral oil) as middle heating agent between fused salt and water, carries out
Stepped heat exchange.Using the eutectic salt of lower temperature, ask that fused salt increases corresponding consumption than high, more using small heating furnace, great Chu
The structure of tank, not only increases the fund input of raw material, but also to increase the volume of molten salt furnace (tank), significantly increases manufacturing cost
And operating cost.Introduce in the middle of heating agent, stepped heat exchange, overall heat exchange complex system is made again, equally to improve manufacturing cost and
Operating cost.

It is not enough.
High-temperature molten salt of the present utility model includes with water interval heat-exchanger rig：Electric heater in tank body and tank body is constituted
Closed molten salt furnace, the suction being made up of feed pipe, fused salt and water- to-water heat exchanger, return pipe, circulating pump, radiator or hot water storage tank
Hot water cyclesystem, improvements introduced is：The heat exchanger of fused salt and water is the single tube or calandria heat exchanger being placed in fused salt, single tube
Or threeway electromagnetic switching valve, two of the threeway electromagnetic switching valve of feedwater side are installed in the two ends that calandria heat exchanger is stretched out outside molten salt furnace
Import connects water-circulating pipe and pre- cold wind blast pipe respectively, and two outlets of the threeway electromagnetic switching valve of backwater side are connected back to respectively
Water pipe and pre- cold wind exhaust duct, blast pipe air inlet install air-cooler, temperature of molten salt sensor are installed in fused salt, in heat exchanger
Tube wall temperature sensor is installed on tube wall, circuit, middle control circuit output threeway electromagnetism switching are controlled in whole temperature sensor accesses
Valve, air blower, water-circulating pump, the control electric current of molten salt heater electromagnetic switch.
It is basic technical scheme of the present utility model above.
For prevent under individual cases water formed in single tube or calandria heat exchanger some vapor make water circulation system be pressurized and
Pinking, increases in water circulation pipe and connects between single tube or calandria heat exchanger in Buffer Water Tank, Buffer Water Tank and molten salt furnace
Feed pipe and return pipe are connect, the porous steam shock absorbing impact-absorbing shell of backwater pipe end mounting cylinder shape stretched into Buffer Water Tank, buffering
There are water-cooled system feedwater interface and cooling system backwater interface on water tank, section is surrounded by water-circulating pipe fused salt to reclaim
The heat that absorbs of pre- cold wind, multitube or multiblade gas and water heat exchanger are concatenated on exhaust duct, gas and water heat exchanger is immersed in slow
In the water for rushing water tank.
To prevent from taking away heat to producing gravity flow air in anhydrous single tube in fused salt heating process or calandria heat exchanger,
On pre- cold wind blast pipe and pneumatic valve is installed on exhaust duct.
The course of work of the present utility model is：Molten salt furnace electric heater power supply, fused salt accumulation of heat are connected in the low power consumption period.
In the peak of power consumption period, using the accumulation of heat of fused salt, first the threeway electromagnetic switching valve that heat exchanger stretches out molten salt furnace two ends is switched and connected
Pre- cold wind blast pipe and exhaust duct are connect, is flowed by pre- cold wind in single tube or calandria heat exchanger, inner surface of tube wall temperature is dropped
To water boiling point, then connection feed pipe and return pipe are switched to, enter water-filling and absorb heat process from fused salt.Into low power consumption
When, threeway electromagnetic switching valve switches to pre- cold wind by heat exchanger again, the water between two switching valves automatically outflow or by
Evaporation.First do not start blower fan, heat exchanger passes through without pre- cold wind, fused salt electric heater switch connection, molten salt furnace closing heating.Will
When entering water-filling with fused salt heat exchanging, start blower fan, single tube or calandria heat exchanger inside pipe wall are blown again and are cooled under fine grinding boiling point, is cut
Threeway electromagnetic switching valve is changed, recirculated water is injected into single tube or calandria heat exchanger again, so run repeatedly.
Good effect of the present utility model is：Using pre- cold wind first by the local (single tube in the molten salt furnace of the condition of high temperature
Or Flat-tube heat exchanger inner surface) temperature is down under water boiling point, and then water flowing, it is to avoid the vaporization of water and exchanger tube wall
Zou Ran is cooled down, and realizes water and high-temperature molten salt interval, steady heat exchange.It is not required to reuse low temperature, the heat-exchange system of big quantity fused salt.
Without the intermediate heat transfer mechanism that high boiling liquid is set up between high-temperature molten salt and heat-exchanging water.Simplify what fused salt exchanged heat with water
Device structure, reduces manufacture and operating cost.Improve efficiency of utilization.
