Multiple-energy source yield distributed energy resource system

Abstract

A distributed energy system with multiple energy outputs comprises a fuel drive power machine, an electric generator, an afterburning device, a reforming hydrogen producing device, a hydrogen purifying device and a refrigerating machine. The power machine supplies heat energy to the electric generator for electric generation; flue gas discharged by the power machine and impure tail end gas produced by the hydrogen purifying device after hydrogen purification enter the afterburning device for combustion; flue gas produced by the combustion enters the reforming hydrogen producing device and supplies the reforming hydrogen producing device with heat for reforming hydrogen production; hydrogen obtained from the reforming hydrogen production is outputted after being purified by the hydrogen purifying device; end gas from the reforming hydrogen producing device enters the absorption type refrigerating machine for refrigeration, heating and hot water supply. The distributed energy system with multiple energy outputs makes effective use of energy sources, further improves the efficiency of a distributed energy cogeneration system for refrigeration, heat, electricity and hydrogen, and reduces the emission of harmful gas.

Description

technical field [0001] The invention belongs to the field of energy, and relates to an energy generation system, especially an energy system capable of producing multiple energy sources. Background technique [0002] Traditional distributed energy is a comprehensive processing plant that uses pipeline networks and power grids to provide electricity, hot water, and air-conditioning cooling and heating to the region within a certain range. The system utilizes energy in grades, so the system has high comprehensive energy efficiency and low environmental emissions, which can improve the safety of power supply and reduce losses caused by large-scale power outages. However, in this energy power system, the conversion and utilization of carbon-containing fuel chemical energy is usually converted into heat by direct combustion, and the heat is then converted into mechanical energy due to the limitation of the Carnot cycle efficiency. Based on the grade cascade utilization principle...

However, it is worth noting that the maximum loss of energy grade in the energy power system does not occur in the transfer and conversion of physical energy, but in the combustion process of chemical energy into physical energy

At present, the main method to reduce the grade loss in the fuel combustion process is limited to increasing the initial temperature of the thermodynamic cycle. However, the increase of the temperature of the thermodynamic cycle is still restricted by various factors such as material development. Therefore, the real breakthrough should focus on how Reduce the grade on the energy release side during the release of fuel chemical energy
