Automatic temperature-control cooling system based on high-temperature storage tank

Abstract

The invention provides an automatic temperature-control cooling system based on a high-temperature storage tank. The automatic temperature-control cooling system comprises a cooling air-duct unit and a cooling temperature automatic-control unit. The cooling air-duct unit comprises a left cooling air-duct unit body and a right cooling air-duct unit body which are symmetrically and oppositely arranged, and the cooling temperature automatic-control unit comprises a total controller and a plurality of temperature measuring points. The automatic temperature-control cooling system based on the high-temperature storage tank has the advantages that cooling air ducts are laterally and bilaterally arranged on a concrete layer based on the high-temperature storage tank, outlets of the air ducts are raised up, and through the stack effect, air automatically flows past the cooling air ducts; and meanwhile the temperature measuring points are arranged on a foundation, the cooling air quantity is automatically controlled in an interlocked mode, and the cooling effect is ensured. The automatic temperature-control cooling system based on the high-temperature storage tank achieves a reliable cooling effect for the foundation, improves service performance of the concrete foundation and prolongs the service life of the concrete foundation; and meanwhile the system is low in investment construction cost and basically has no operating cost.

Description

technical field [0001] The invention belongs to the technical field of molten salt heat storage, and in particular relates to an automatic temperature-controlled cooling system for a high-temperature storage tank foundation. Background technique [0002] Most of the large-scale commercial solar thermal power plants are equipped with heat storage systems, which enable the power plants to continue to generate electricity without sunlight, extend the power generation hours of the power plants, and increase the economic benefits of the power plants. [0003] At present, the heat storage system of solar thermal power generation mostly adopts a double-tank molten salt heat storage system. This system stores heat in two large-capacity, high-temperature molten salt storage tanks. The working temperature of the molten salt storage tanks is above 290°C. The design temperature is ≥400°C. Under the conditions of large volume and high temperature, strict requirements are put forward for...

Problems solved by technology

However, when the temperature of the tank body is high, a large amount of heat is still conducted to the concrete layer through the heat insulation layer, making the temperature of the concrete layer reach above 100°C, which exceeds the reasonable use temperature of ordinary concrete, thereby shortening the life of the concrete layer. And then directly shorten the service life of the high temperature storage tank, how to effectively solve the above problems is of great significance
