Abstract

The invention provides a power generation and hydrogen production combined circulating system based on alkali metal thermoelectric conversion, belonging to the field of energy power engineering. The combined circulating system comprises an alkali metal thermoelectric conversion subsystem capable of directly converting thermal energy into electric energy, and a methanol steam reforming hydrogen production subsystem capable of converting residual heat into chemical energy, wherein the alkali metal thermoelectric conversion subsystem mainly comprises an evaporator, a high pressure sodium vapor pipeline, an alkali metal thermoelectric converter, a low pressure sodium vapor pipeline and a condenser; and the methanol steam reforming hydrogen production subsystem mainly comprises a reactor, a preheater, a condensation absorber, a vaporization superheater, a conduction oil pump, a methanol pump, a demineralization water pump and a pressure swing adsorption separating device. Compared with theconventional energy system, the system is a multifunctional energy system with multi-energy (thermal energy and methanol) input and multi-product (electric power and hydrogen) output, not only can realize thermoelectric direct conversion of the thermal energy, but also can realize thermal chemical utilization of the residual heat.

Description

Technical field: [0001] The name of the invention is a combined cycle system of power generation and hydrogen production based on alkali metal thermoelectric conversion, which belongs to the field of energy and power engineering. Background technique: [0002] Electric energy is the most ideal secondary energy source, which is used to supply the needs of various sectors of the national economy and people's lives. The production process of electric energy can be divided into dynamic power generation and static power generation. Traditional power generation, generally belonging to dynamic power generation, refers to the use of power generation devices to convert water energy, thermal energy of fossil fuels (such as coal, oil, natural gas, etc.), nuclear energy, solar energy, wind energy, geothermal energy, ocean energy, etc. into electrical energy. production process. The current electric energy production is mainly dynamic power generation, that is, heat energy is first con...
