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
The present invention relates to diesel oil or petrol engine auxiliary combustion technology, particularly a kind of assisted combustion device that utilizes using waste heat from tail gas gasification alcohols.
Background technique
The facing mankind of today the global energy crisis of the non-renewable energy resources exhaustions such as oil.The essential measure that solves oil shortage and auto-pollution problem is the combustion efficiency that improves existing fuel oil unit, produces in addition and use reproducible clean fuel.
Aspect raising oil inflame efficiency, the methods such as ultrasonic emulsification, interpolation combustion improver are arranged.The shortcoming of these methods is that cost is high, can't on high-power fuel oil unit, apply.
In addition, the energy that engine exhaust emission falls has accounted for burning and has discharged 40% of total energy, and this part energy is not well recycled at present.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of simple in structure, assisted combustion device that utilizes using waste heat from tail gas gasification alcohols of being easy to realize is provided; The high temperature that utilizes tail gas is after liquid alcohols gasification, then the gaseous state alcohols entered in cylinder carry out mixed combustion with fuel oil, greatly improve combustion efficiency.
The present invention is achieved through the following technical solutions:
A kind of assisted combustion device that utilizes using waste heat from tail gas gasification alcohols, comprise housing 1, be placed in inner bag 2 in housing 1, be placed in housing 1 support 3 for fixing inner bag 2, be wrapped in the copper pipe 4 of inner bag 2 outer walls, for the gas inlet 5 that connects offgas duct, for the tail gas of discharging tail gas, export 6;
There is gap between the inwall of the outer wall of described inner bag 2 and housing 1;
The two ends of described copper pipe 4 pass housing 1, and wherein an end is for sucking outside liquid alcohol, and an other end is for the connecting engine admission line.
The rear and front end of described inner bag 2 is the semielliptical shape, and the middle part of inner bag 2 is the cylindrical structural with two through hole 2-2, and the front end of inner bag 2 has a stomidium 2-1 who communicates with two through hole 2-2 at inner bag 2 middle parts.
Described gas inlet 5 is over against the stomidium 2-1 of inner bag 2, and gas inlet 5 is greater than stomidium 2-1.
Described housing 1 is that two is little broad in the middle.
With respect to prior art, the present invention has following advantage and beneficial effect:
When tail gas from gas inlet enters, liquid alcohol in copper pipe absorbs rapidly the exhaust heat-energy gasification, and enter in cylinder and carry out mixed combustion with fuel oil by admission line, both improved the efficiency of burning, recycle again the waste heat of tail gas, and brought into play liquid alcohol (ethanol or the methyl alcohol) effect of fuel as an alternative.
The copper pipe spirality is wrapped in to inner bladder outer wall, is conducive to enlarge hot area.
Inner bag can adopt fine copper, has heat storage capacity strong, and the heat that can absorb effectively fully in tail gas is used, and realizes the function of the interior liquid alcohol of gasification copper pipe rapidly.
The liquid alcohol origin of heat used of gasification, in using waste heat from tail gas, had both reduced the temperature of tail gas, had alleviated urban heat land effect, had also reclaimed the portion of energy in tail gas.
The middle part of inner bag is the cylindrical structural with two through holes, the front end of inner bag has two stomidiums that through hole communicates with inner bag middle part, according to fluid mechanics principle, the gas flow rate of now being discharged by two through holes is accelerated, pressure reduces, mineralization pressure is poor, is conducive to tail gas by copper pipe, reduces the impact of copper pipe back pressure.
This device technique means are simple and easy to do, with low cost; Long service life.
The accompanying drawing explanation
Fig. 1 is the assisted combustion device structural representation that the present invention utilizes using waste heat from tail gas gasification alcohols.
Embodiment
