Column-type acceptor for solar tower-type thermal electricity generation and application method thereof

Abstract

The invention provides a column-type acceptor for solar tower-type thermal electricity generation and an application method thereof. The acceptor comprises a tower body support frame supporting a thermal-collecting acceptor, a top sealing cap is fixedly mounted on the top portion of the thermal-collecting acceptor, an insulation layer is arranged on the periphery of the thermal-collecting acceptor in a sleeve mode by an insulation layer support frame, a mechanism matching with an insulation layer lifter is mounted inside the insulation layer, and the insulation layer moves vertically along the for on-line automatic data filling and reporting insulation layer lifter under the action of external force. When heat preservation is needed for the thermal-collecting acceptor, the insulation layer is moved upwards to the top portion and fully covers the thermal-collecting acceptor, and moreover, the periphery of the insulation layer is sealed tightly with the top sealing cap. By a closeable insulation device, the heat loss of the heat-collecting acceptor at low temperature and in high wind weather can be decreased effectively, and the risk of solidification of the heat-conducting medium in the heat-collecting acceptor can also be avoided effectively. In addition, the column-type acceptor for solar tower-type thermal electricity generation also has the advantages of simple structure and convenience in control and enables quick protection of the heat-collecting acceptor to be achieved.

Description

technical field [0001] The invention belongs to the technical field of solar energy application, and in particular relates to a solar tower type thermal power generation column receiver and a method for applying the receiver. Background technique [0002] Solar thermal power generation technology is one of the effective ways to solve environmental pollution and energy crisis in the 21st century. Solar thermal power generation mainly includes three methods: trough type, dish type and tower type. Among them, tower solar thermal power generation is the most economical form of power generation in large-scale solar power generation. [0003] For the tower solar thermal power generation system, the thermal receiver is the main component that absorbs solar radiation energy. The molten salt circulates inside the thermal receiver, and the thermal receiver uses the absorbed solar energy to heat the molten salt, and then melts the high temperature The thermal energy of the salt is co...

Problems solved by technology

[0004] In the prior art, under low temperature and windy weather, the heat loss of the heat collecting receiver is serious, thereby reducing the power generation efficiency of the tower solar thermal power generation system; moreover, there is also the risk of the heat collecting receiver being frozen, making the heat collecting receiver not working
