Auxiliary combustion device using tail gas waste heat to gasify alcohol

Abstract

The invention discloses an auxiliary combustion device using tail gas waste heat to gasify alcohol. The auxiliary combustion device comprises a shell, an inner container disposed in the shell, a support disposed in the shell and used for fixing the inner container, a copper pipe wound on the outer wall of the inner container, a tail gas inlet for being connected with a tail gas pipe and a tail gas outlet for discharging tail gas. A gap is reserved between the outer wall of the inner container and the inner wall of the shell. Two ends of the copper pipe penetrates out of the shell, one end is used for sucking in external liquid alcohol, and the other end is used for being connected with an gas inlet pipeline of an engine. When tail gas enters from a device inlet, the liquid alcohol in the copper pipe absorbs tail gas heat energy fast to be gasified, the gasified alcohol enters an engine air cylinder for mixed combustion, combustion efficiency is increased, waste heat of the tail gas is recycled, and the function of the liquid alcohol serving as alternative fuel is brought into play.

Description

technical field [0001] The invention relates to an auxiliary combustion technology for a diesel or gasoline engine, in particular to an auxiliary combustion device for gasifying alcohols by using exhaust waste heat. Background technique [0002] Today's human beings are facing a global energy crisis in which non-renewable energy sources such as petroleum are exhausted. The fundamental measure to solve the problem of oil shortage and automobile pollution is to improve the combustion efficiency of existing fuel units, as well as to produce and use renewable clean fuels. [0003] In terms of improving fuel combustion efficiency, there are methods such as ultrasonic emulsification and adding a combustion aid. The disadvantage of these methods is that they are costly and cannot be popularized and applied to high-power fuel oil units. [0004] In addition, the energy emitted by engine exhaust accounts for 40% of the total energy released by combustion. At present, this part of e...
