Embodiment Construction

[0022] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] The following descriptions are only preferred embodiments of the present invention, and therefore do not limit the protection scope of the present invention.

[0024] This embodiment is a storage device capable of continuously providing 6 hours of superheated steam for a 500kW-class solar thermal power generation system that directly generates steam. During the storage process, the superheated steam produced by the solar collector has a pressure of 2.5MPa, a temperature of 305°C, and a steam flow of 7.4 tons / hour, of which 3.8 tons / hour flows into the superheated steam storage device, and the storage time is 6 hours. During the release process, the superheated steam storage device provides 3.6 tons / hour of superheated steam to the power gener...

Abstract

The invention discloses a novel superheated steam storing device and a method. The device comprises a packed bed heat accumulator, a steam heat accumulator, a pressure regulating valve group and relevant pipelines and valves, wherein a hot end pipeline of the packed bed heat accumulator is connected with a main steam pipeline of a solar thermal power generation system, a cold end pipeline of the packed bed heat accumulator is provided with two ways of branched pipes, the two ways of branched pipes are connected with a steam inlet pipeline and an exhaust steam pipeline of the steam heat accumulator respectively, and the pressure regulating valve group is arranged on the exhaust steam pipeline of the steam heat accumulator. By means of the device, heat of superheat and latent heat of vaporization of the superheated steam can be stored respectively, high quality storing of energy is achieved, heat and steam can be stored in the same device, the system structure is remarkably simplified, and equipment investment and operating maintenance costs are saved.

Description

Technical field [0001] The invention relates to a heat storage device and method, in particular to a superheated steam storage device and method, and is particularly suitable for a solar thermal power generation system that directly generates steam. Background technique [0002] Solar thermal power generation is an important direction of solar thermal utilization, and it is one of the most economical means to achieve high-power power generation and replace conventional energy. There are three common methods of solar thermal power generation: tower solar thermal power generation, trough solar thermal power generation, and dish solar thermal power generation. Trough solar thermal power generation is currently the most mature and commercialized thermal power generation method. [0003] At present, the solar thermal power generation system that directly generates steam represents an advanced trough solar thermal power generation system. Compared with the traditional dual-circuit solar ...
