Abstract

The invention relates to a natural gas heat and cold electric energy supply device based on fused salt heat storage. At present, no natural gas heat and cold electric energy supply device which is simple in structure and reasonable in design and can further improve the comprehensive utilization of energy and the energy supply stability exists. The natural gas heat and cold electric energy supply device comprises a fuel gas electric generator, a waste-heat utilization device, a gas-gas heat exchanger and a fan, wherein the fuel gas electric generator is connected with the waste-heat utilization device through a pipeline; the waste-heat utilization device is connected with the gas-gas heat exchanger through a pipeline; and the fan is connected with the gas-gas heat exchanger through a pipeline. The device is characterized by further comprising a fused salt phase change heat storage device, and the fused salt phase change heat storage device is connected to the fuel gas electric generator, the waste-heat utilization device and the gas-gas heat exchanger through pipelines respectively. The natural gas heat and cold electric energy supply device is reasonable in structural design and can further improve the comprehensive utilization rate of the energy and the energy supply stability.

Description

technical field [0001] The invention relates to a natural gas cooling and heating power supply device, in particular to a natural gas cooling and heating power supply device based on molten salt heat storage, which can directly supply cooling, heating and power supply to user buildings, and has high energy utilization efficiency and the ability to store energy. Background technique [0002] Due to its own defects, the traditional large grid power supply method can no longer meet the needs of today's society for the quality, safety and reliability of energy and power. In large-scale interconnected power systems, local accidents are easy to spread, and centralized large power grids cannot flexibly track changes in power loads. As a new type of energy system, distributed energy has been widely valued worldwide due to its advantages of safety, economy, reliability, high energy utilization rate, and environmental friendliness. [0003] At present, distributed energy systems are...
