Ship biomass gasification, refrigeration and power generation system utilizing waste heat

Abstract

The invention relates to a ship biomass gasification, refrigeration and power generation system utilizing waste heat, and belongs to the technical field of ship renewable energy utilization. The system comprises a biomass gasification and purification unit, an engine waste gas recycling unit, a lithium bromide absorption type refrigeration unit, an oxygen-enriched combustion power generation unit, a water-gas separation unit and a sewage treatment unit. The ship biomass is used as a raw material, waste heat is used for driving the ship biomass to be gasified, the ship household garbage is recycled, and the utilization efficiency of low-level heat energy is improved. Hydrogen-doped combustion of engine fuel is achieved through the prepared synthesis gas, the combustion process of an engine is improved, and emission of pollutants is reduced; and power generation and absorption refrigeration both adopt an oxygen-enriched combustion mode, and high-temperature flue gas generated by combustion is introduced into the biomass gasification device again for heat exchange, so that the heat of the high-temperature flue gas is fully utilized, and the energy utilization efficiency is improved. The high-temperature flue gas only contains CO2 and H2O, so that carbon capture can be realized conveniently.

Description

technical field [0001] The invention relates to a marine biomass gasification, refrigeration and power generation system utilizing waste heat, and belongs to the technical field of marine renewable energy utilization. Background technique [0002] Ships produce and discharge a variety of pollutants during their operation. Among them, ship garbage and engine exhaust are the two main sources of pollution. As emission control laws become more and more stringent, as well as the environmental crisis and energy crisis faced by human beings, the task of finding a clean and renewable energy source is imminent. Biomass energy has the characteristics of renewable, wide sources of raw materials, low carbon and environmental protection. Ship biomass is mainly domestic waste such as kitchen waste, leftovers and domestic sewage. The synthesis gas produced by ship biomass gasification is a hydrogen-rich gas with wide combustion limit, low ignition energy, high energy density and wide ap...
