Complementary distributed energy system using internal combustion engine exhaust to integrate thermochemical processes

Abstract

The invention provides a complementary type distributed energy system integrating internal combustion engine tail gas into the thermochemical process. The system comprises an internal combustion engine power generation subsystem, a thermochemistry waste heat utilization subsystem, an absorption refrigeration subsystem and a low-temperature exhaust waste heat utilization subsystem. According to the system, based on the energy utilization principle of parallel temperature and gradient utilization, exhaust waste heat recovery is conducted through thermochemical reaction, absorption refrigeration, heat supply and the like in sequence, high-temperature exhaust waste heat is utilized scientifically and reasonably in a gradient mode, heat, electric and cold diversified energy product output is achieved, and the energy utilization efficiency and grade of exhaust waste heat are improved greatly.

Description

technical field [0001] The invention relates to the technical field of energy utilization, in particular to a complementary distributed energy system utilizing exhaust gas from an internal combustion engine to integrate thermochemical processes. Background technique [0002] With the continuous and rapid development of my country's social economy, the demand for energy is also increasing year by year. The large consumption of fossil fuels such as coal, oil and natural gas has also caused serious environmental pollution, which will hinder the sustainable development of the future economy and society. . In addition, due to my country's large population and relative scarcity of per capita resources, energy, resources and environmental issues are particularly prominent. [0003] China's total primary energy production increased from 1.35 billion tons of standard coal in 2000 to 3.4 billion tons of standard coal in 2013, and its annual primary energy consumption also increased fr...

Problems solved by technology

For traditional heating systems, although boilers convert most of the chemical energy of fossil fuels into useful heat energy and provide it to heat users, the high-temperature flue gas generated by combustion is directly used to heat lower-temperature steam or hot water. Great loss of work ability

In terms of refrigeration, in order to meet the normal operation of the electric-driven air conditioner in summer, the power plant needs to increase the power production, which also causes a huge loss of heat energy.
