CO2 catching device

Abstract

The invention relates to a CO2 catching device, which not only can meet oxygen enrichment combustion, but also can catch CO2 exhausted from an internal combustion engine by the aid of a heat absorption effect of liquid oxygen vaporization, so that zero emission of the engine is realized. The CO2 catching device comprises a shell, an inlet (1), a condensate tube (2), a first CO2 condensing sieve (3), a first dry ice collector (4), a second CO2 condensing sieve (5), a second dry ice collector (6), a gas outlet (7), a liquid oxygen inlet (8) and a liquid oxygen guiding block (9). Liquid oxygen is vaporized into oxygen gas, the oxygen gas and a part of uncondensed CO2 jointly enter the internal combustion machine to realize oxygen enrichment combustion, and CH and CO are eliminated. After being used with the device, the internal combustion engine can work in narrow spaces needing zero emission, such as military adit construction vehicles, tunnel excavators, drilling generators, submarine generators, military missile launching vehicles and the like.

Description

technical field [0001] The present invention relates to a novel CO 2 Capture devices, specifically involving liquid oxygen solidified CO 2 device. Background technique [0002] In today's increasingly stringent requirements for energy saving and environmental protection, the research on energy saving and environmental protection of engines has become a current research hotspot. Oxygen-enriched combustion is one of the main ways to save energy. Oxygen-enriched combustion can make fuel burn more fully, eliminate CH, CO and other pollutants, and obtain higher pressure peaks, thereby improving the engine's working ability. But ordinary air contains nitrogen, and burning hydrocarbon fuels produces CO 2 and NO x The problem of pollutants, so start with the engine gas, and study the internal combustion engine to solidify CO with liquid oxygen 2 And the new method of using liquid oxygen to support combustion has considerable practical significance. The realization of this metho...
