Oxygen-enriched combustion and liquid oxygen carbon sequestration system for internal combustion engine and working method thereof

Abstract

The invention discloses an oxygen-enriched combustion and liquid oxygen carbon sequestration system for an internal combustion engine and a working method thereof. The oxygen-enriched combustion and liquid oxygen carbon sequestration system comprises a CO2 capturing device (1), an air inlet pipe pressurizing device (2), a liquid oxygen transferring pipe (3), a liquid oxygen storage tank (4), an internal combustion engine air inlet pipe (5), an internal combustion engine (6), an internal combustion engine exhaust pipe (7), a condensed water pipe (8), a dry ice storing device (9) and a dry ice collecting pipe (10). The CO2 capturing device (1) is used for gasifying liquid oxygen to oxygen gas; the oxygen gas commonly enters the internal combustion engine with a part of non-condensed CO2; oxygen-enriched combustion is carried out; and the generation of CH and CO is eliminated. Meanwhile, the CO2 further can be captured, so that zero discharge of the internal combustion engine can be realized.

Description

technical field [0001] The invention relates to an internal combustion engine oxygen-enriched combustion and liquid oxygen carbon fixation system and a working method thereof. Background technique [0002] At present, the requirements for energy saving and emission reduction are becoming increasingly stringent, energy saving and environmental protection have become the focus of research, and the energy saving technology of internal combustion engines has also become the focus of research. Oxygen-enriched combustion technology can significantly increase combustion efficiency and flame temperature, thereby improving combustion and emission performance. It is a high-efficiency and energy-saving technology with broad application prospects. Oxygen-enriched combustion can increase temperature and pressure peaks, making soot, CO and SO 2 The emission is reduced, but due to the excess air, which contains a large amount of nitrogen, the NO x Emissions increase. If the pure O desig...
