Problems solved by technology

[0006] However, the steam injection cycle increases the water consumption of the system. While ensuring the normal operation of the system and improving efficiency, it is also worth studying to effectively recover the moisture in the exhaust gas.
At present, the recovery of water in the exhaust smoke of thermal power plants is mainly through physical condensation by adding a condenser, or using special physical absorption membranes and other devices to recover water. The main disadvantage is that due to the existence of non-condensable gases in the exhaust smoke The volume of the equipment is too large and complicated, it is difficult to manufacture, and the condensation effect is not good. Therefore, it is necessary to study the methods of moisture recovery in flue gas based on different principles

Abstract

The invention relates to a chemical type water recycling method and device based on a solar energy gas turbine system. Air is pressurized through an air compressor to be mixed with water vapor, a mixture enters a heat regenerator for recycling tail gas waste heat, is heated continuously through a solar thermal collector, and then enters a combustor, high temperature and high pressure wet smoke enters a gas turbine to act, and tail gas sequentially passes through two dividing wall type reactors through switching of a control valve; and filled reactants are subject to dehydration and water suction reactions, continuous recycling of water in the wet smoke is achieved, the water vapor generated by the dehydration reaction enters the system again to be mixed with compression air, and dry smoke obtained after the water suction reaction is discharged out of the system. According to the chemical type water recycling method and device, the solar energy and the waste heat resources are sufficiently used, the system efficiency is improved, recycling of the water vapor in discharged smoke of a steam reinjection type gas turbine power generation system is achieved, the system water consumption is greatly reduced, the energy-saving and emission-reducing effect is shown, and the good economic benefits and social benefits are achieved.

Description

technical field [0001] The content of the present invention relates to the technical field of solar gas turbines, in particular to a method and device for chemically recovering water based on solar gas turbine systems. Background technique [0002] Solar energy is a clean, non-polluting renewable energy source. Its development and utilization are of great significance for alleviating the current pressure of fossil energy consumption and environmental pollution. [0003] Solar thermal power generation technology is to convert solar thermal energy into electric energy technology. There are four main methods of solar energy focusing: dish type, tower type, trough type and Fresnel type. The direct thermal power generation efficiency of solar thermal power generation technology is low, generally around 20%, and a large amount of light-to-heat conversion energy has not been utilized. In addition, a single solar thermal power generation system cannot provide sufficient energy at n...
