System and method for water spray injection type pulse steam electric power generation

Abstract

The invention discloses a system and method for water spray injection type pulse steam electric power generation. A temperature sensor (26), a pressure sensor (25) and a flow meter (82) are respectively connected with a signal transmission line of a main control unit (9), a control line of the main control unit (9) is connected with a water injection valve (23), a steam release valve (22) and a water pump (81). Water is injected by force in a quantitative mode, the quantitative water is subjected to instant vaporization to be steam in the high-temperature environment of a steam generator, the steam pushes a turbine to do work and drives an electric generator to generate electricity to complete pulse work, and efficienct and feasible thermoelectric conversion is achieved. A circulation pulse working mode is adopted, and the system and method break through the tradition that a great amount of water is heated in a one-time mode for doing work, reduce water consumption and effectively improve conversion efficiency from thermal energy to steam potential energy. Under the control of a controller, the quantitative water is injected by force and rapidly and completely is vaporized in the high-temperature environment of the steam generator, the vaporization rate of the water is improved, and therefore the conversion efficiency from the thermal energy to the steam potential energy is further improved.

Description

technical field [0001] The invention relates to a water injection injection pulse steam power generation system and method. Background technique [0002] Energy shortage and environmental pollution have become major problems facing human development and have attracted the attention of the society. Solar energy is a clean and renewable energy. The utilization of solar energy is of great significance to the progress and development of society. The use of solar thermal power generation is one of the important means of solar energy utilization. The thermal energy converted from solar energy heats the working medium to generate steam through heat exchange, which drives the steam turbine generator set to generate electricity. Solar steam generators have a series of advantages such as low cost, high heat absorption, and cleanliness, so solar steam generators are important and feasible thermoelectric conversion methods. [0003] However, traditional steam power generation systems ...

Problems solved by technology

However, this patent needs to use electric auxiliary heating to generate high-temperature and high-pressure steam, which has high energy consumption and cost

In addition, this patent uses pressure difference for water injection and steam release to create a so-called "nature" closed circuit. The control accuracy of water injection and steam release using pressure difference is low, and the energy conversion efficiency from heat energy to steam potential energy is not good. to guarantee
