Solar molten salt sleeve pipe type steam generation method and device thereof

Abstract

The invention provides a solar molten salt cannula-typed vapor generating method and a device thereof. The generating method comprises the following steps: a refractory selective absorbing coat layer of a jacket outer wall is used for absorbing and irradiating solar energy in real time and transmitting heat to molten salt medium inside a molten salt cannula, and then to water or vapor inside a snakelike inside tube until the vapor is stably generated by the whole device; the irradiation intensity of solar energy is adjusted through the melting heat absorption or the solidifying heat discharging of the molten salt medium inside the molten salt cannula or a salt collecting slot when exceeding a designed intensity range, thus maintaining the stable vapor generation of the whole device. The generating device is an integral structure that is formed by arranging the salt collecting slot at the left and right sides of the molten salt cannula, the molten salt cannula consists of a jacket and a snakelike inner pipe, the jacket is communicated with the salt collecting slot, a vapor outlet is arranged at an upper end of the snakelike inner pipe, and a water flow inlet is arranged at a lower end of the snakelike inner pipe; an air vent is arranged at an upper end of the whole device. The generating device has simple structure and stable state of exported vapor, can bear larger heat flow density and frequent thermal shock, and has greater temperature range.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a solar molten salt casing type steam generation method and a device thereof. Background technique [0002] my country is facing the double huge pressure of total energy supply and ecological environment. The energy issue is a long-term bottleneck restricting economic and social development, and it has always been a major issue that must be paid close attention to. Therefore, the development and utilization of solar energy has become an important part of the energy strategy of today's society. The use of solar energy to generate steam is one of the main forms of high temperature and large-scale heat utilization of solar energy. Steam is widely used in power generation, food, chemical, pharmaceutical, printing and dyeing, textile, brewing and other industries due to its advantages of convenient transportation and energy transfer. Therefore, the research on solar steam gene...

Problems solved by technology

The systems using these three substances as the heat-absorbing medium have their own advantages and disadvantages: (1) In the solar air system, the air flows through the heat absorber and the temperature rises to above 700°C, and then it is sent into the steam by the fan to generate steam generator

These will increase the associated power consumption of the system
