Abstract

The utility model discloses a saving type molten salt tank. The tank comprises a cylindrical tank body (1), electric heaters (2) and a molten salt pump suction pipe (3), wherein the electric heaters (2) are arranged at the bottom inside the cylindrical tank body (1); the molten salt pump suction pipe (3) is arranged inside the cylindrical tank body (1); a conical tank bottom (4) is arranged at the bottom of the cylindrical tank body (1); a position where the conical tank bottom (4) is connected with the cylindrical tank body (1) is located below the electric heaters (2); and a hollow structure is arranged between a molten salt tank foundation (5) and the conical tank bottom (4). With the adoption of the tank, the molten salt consumption below a safe liquid level can be reduced, so that the investment cost and the manufacturing cost are reduced.

Description

A kind of economizing type fused salt tank
Technical field
The utility model relates to a kind of fused salt tank, and particularly a kind of economizing type fused salt tank, belongs to solar energy thermal-power-generating field.
Background technology
Along with scientific and technological progress, the depletion rate of non-renewable resources is more and more faster, and in order to protect the ecological balance, people develop renewable resources just energetically.Use solar electrical energy generation can save every year a large amount of coal use amounts, therefore the each state in the whole world is all in research solar energy thermal-power-generating technology, and solar energy thermal-power-generating technology is ripe not enough at present, and a lot of technology all have much room for improvement.
Fused salt hold over system is the important component part at solar energy thermal-power-generating station, and wherein fused salt tank is the important component part of fused salt hold over system.Conventional fused salt tank, will arrange some groups of electric heaters conventionally at the bottom of its tank.For submergence electric heater and the minimum suction inlet degree of depth that maintains pump for liquid salts, the fused salt degree of depth in fused salt tank will keep certain safe liquid level, fused salt under this safe liquid level do not participate in system fill heat and heat release circulate, this part fused salt does not make full use of, in a kind of state of idle waste, and fused salt cost is also higher, is unfavorable for saving investment and reduces cost.
Utility model content
The purpose of this utility model is, a kind of economizing type fused salt tank is provided, and it can reduce the fused salt consumption under safe liquid level, thereby reduces cost of investment and cost.
The technical solution of the utility model: a kind of economizing type fused salt tank, comprise cylindrical tank, electric heater and pump for liquid salts suction line, electric heater is arranged on the bottom in cylindrical tank, pump for liquid salts suction line is arranged in cylindrical tank, at the bottom of the bottom of cylindrical tank is provided with conical tank, at the bottom of conical tank, be positioned at the below of electric heater with the junction of cylindrical tank; Between at the bottom of fused salt tank base and conical tank, it is hollow structure.At the bottom of conical tank is set, effectively reduce the space of safe liquid level below, thereby reduced the use amount of fused salt.
In aforesaid economizing type fused salt tank, at the bottom of described conical tank, adopt concrete material to make.
In aforesaid economizing type fused salt tank, be provided with support column between at the bottom of described fused salt tank base and conical tank, described support column is arranged ringwise; The surface of fused salt tank base is provided with heat insulation layer.
In aforesaid economizing type fused salt tank, described support column is reinforced concrete structure.
In aforesaid economizing type fused salt tank, in the hollow structure between at the bottom of described fused salt tank base and conical tank, be provided with concrete, the below of fused salt tank base is provided with round steel pipe side by side.Fused salt tank base surface arranges heat insulation layer, place, the gap fill concrete between adjacent circular steel pipe or insulation material.Below fused salt tank base, be provided with side by side the heat waste that round steel pipe can effectively reduce Concrete Filled thing below the conical surface.
Compared with prior art, the utility model is by the bottom of arranging conical tank, effectively reduced the volume at the bottom of tank, saved the consumption that does not participate in system storage system fused salt at the bottom of tank by this structure, effectively reduces cost of investment.
By heat insulation layer and round steel pipe are set at the bottom of tank, can effectively play adiabatic object, effectively prevent that heat from losing from tank underflow.
