The present preheating scheme adopts the hot-blast furnace preheating mode mostly, and this mode system is simple, and the investment is low, and the security is high, but still has following problem: firstly, along with the technical development, the storage tanks are increasingly large in size, the existing preheating system generally adopts a set of preheating device to respectively preheat a plurality of storage tanks, the preheating time is too long, and the construction period is seriously influenced; secondly, the high-temperature preheated gas is directly discharged into the atmosphere after being heated in the molten salt storage tank, thereby causing serious waste of energy.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the defects existing in the prior art and providing a molten salt storage tank preheating system with short preheating time and high energy utilization rate.
In order to achieve the above object, the utility model provides a solar photothermal power fused salt storage tank system of preheating, its characterized in that: including high temperature fused salt storage tank and the low temperature fused salt storage tank of establishing ties in proper order, the air inlet of high temperature fused salt storage tank is established ties through the air inlet pipeline and is had heating furnace and fan, the gas outlet of low temperature fused salt storage tank pass through the return air pipeline with the fan intercommunication.
Further, the high-temperature molten salt storage tank and the low-temperature molten salt storage tank are provided with manholes, and the air outlet end of the air inlet pipeline is communicated with the manholes.
Furthermore, the air outlet end of the air inlet pipeline is also connected with a nozzle which is a venturi nozzle.

Compared with the traditional one-by-one independent preheating, the preheating time is greatly reduced; meanwhile, the high-temperature flue gas preheats the high-temperature molten salt storage tank, the temperature of the flue gas is reduced, and then the low-temperature molten salt storage tank is preheated, and the temperature of the flue gas is matched with the preheating temperature required by the storage tank; the preheated flue gas returns to the heating furnace again for cyclic utilization, and the energy utilization rate of the system is improved.
Drawings
Fig. 1 is a schematic diagram of a face tank preheating system.
The components in the figures are numbered as follows: the system comprises a high-temperature molten salt storage tank 1, a low-temperature molten salt storage tank 2, a heating furnace 3, a fan 4, a temperature measuring device 5, a flow measuring device 6, a nozzle 7, an air inlet pipeline 8, an air return pipeline 9 and a manhole 10.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings, which are not intended to limit the scope of the present invention.
As shown in fig. 1, the solar photo-thermal power generation molten salt storage tank preheating system comprises a high-temperature molten salt storage tank 1 and a low-temperature molten salt storage tank 2 which are sequentially connected in series, wherein an air inlet of the high-temperature molten salt storage tank 1 is connected in series with a heating furnace 3 and a fan 4 through an air inlet pipeline 8, and an air outlet of the low-temperature molten salt storage tank 2 is communicated with the fan 4 through an air return pipeline 9; the temperature measuring device 5 and the flow measuring device 6 are respectively bypassed on the air inlet pipeline 8 and the air return pipeline 9. Like this, the high temperature flue gas that the fan produced after with burning in the heating furnace flows through high temperature fused salt storage tank and low temperature fused salt storage tank in proper order, and the temperature of flue gas just in time matches with the required preheating temperature of two storage tanks, preheats one by one alone for the storage tank for the tradition, and whole preheating time significantly reduces, and the flue gas after the low temperature fused salt storage tank preheats gets back to cyclic utilization in the heating furnace once more, has improved entire system's energy utilization.
Among the above-mentioned technical scheme, the upper end of high temperature fused salt storage tank 1 and low temperature fused salt storage tank 2 is opened there is manhole 10, and the end of giving vent to anger of air inlet pipe way 8 is connected with nozzle 7, and nozzle 7 adopts the venturi nozzle, and the nozzle passes the storage tank and the slant sprays down through the manhole. Like this, need not to set up the hole of usefulness of preheating alone on the storage tank, adopt the venturi nozzle to make the injection angle of flue gas bigger, the flue gas is more even that flows in the storage tank, and preheating effect is better.
