Embodiment Construction

[0017] Figure 1 is a schematic diagram of the present invention. In Figure 1, the operating principle of the device can be explained step by step as follows:

[0018] The invention is a funnel-shaped converging solar concentrator that can collect sunlight to form a high-density light energy flow, and utilizes a transparent light inlet window with light transmission but heat insulation to guide light energy into an energy storage device for storage. Then through the thermal oil heat supply cycle and the thermal power conversion cycle, the solar thermal power conversion device is realized. There are one or more funnel-shaped concentrating solar concentrators (1) in the device. The funnel-shaped concentrating solar concentrators (1) gather sunlight at a high density, and pass the sunlight through the transparent light inlet window (2). Imported into the energy storage body (6) inside the energy storage device (3) for high-temperature thermal energy storage, the funnel-shaped con...

Abstract

The invention relates to a converging type solar thermal power device capable of condensing sunlight, storing heat using high temperature phase change energy storage material and driving double loops, belonging to the technical field of solar energy collection and solar energy heat utilization. The device comprises a funnel-shaped converging type solar energy condenser, a transparent light transmitting window, an energy accumulator, a high temperature heat-conducting oil heat supply circulating system, a superheated steam generator, and a Rankine cycle-based heat-power converting system. The sunlight is condensed by the funnel-shaped converging type solar energy condenser, and entered into the energy accumulator through the transparent light transmitting window to realize high temperature storage therein, the high temperature heat-conducting oil heat supply circulating system transmits the high temperature in the energy accumulator to the superheated steam generator to heat working fluid to generate high pressure high temperature superheated steam therein, and converts heat energy to power through thermodynamic cycle. The invention is a device for supplying power or electric energy for user by condensing sunlight, storing heat using high temperature phase change energy storage material, and driving heat-power converting system using high temperature heat energy.

Description

Technical field [0001] The invention belongs to the technical field of solar energy concentration and solar thermal utilization. Specifically, it is a device that can use light pipes or optical fibers to guide concentrated sunlight, and use high-temperature phase-change energy storage materials to store heat, so as to provide users with high-temperature heat energy. Background technique [0002] In the current relatively mature solar thermal power system, there are mainly two ways of trough solar concentrated heat collection and tower concentrated solar heat collection. However, these two types of solar thermal power systems can generally only be built into large systems, generally above 1MW, because the construction costs of small systems are high and there is no promotion value. However, in many cases, small-scale users also have a strong demand for solar thermal power systems. Therefore, the two solar thermal power systems of trough-type concentrating heat collection and...
