Abstract
The present invention relates to a self-suction combustion-promoting purifier for engine tail gas. Light combustible gas is separated by fixed vanes after the engine tail gas passes through a tail gas inlet. The light combustible gas can pass through a light combustible gas collecting conical tube, and then return to the engine through a reclaiming tube for secondary combustion to do work. The residual tail gas is mixed with air sucked from a fresh air supplying tube and then enters a mixed combustion conical tube for mixed combustion by the acceleration of a spraying conical tube. Then the residual tail gas is discharged from a tail gas discharging port to achieve purifying effect. The system has the advantages of simple and reasonable structure, low cost, ideal purifying effect and long effective purification life.
Description
The present invention relates to a kind of engine tail gas purifier, refer in particular to a kind of self-suction combustion-promoting purifier for tail gas of engine.
Engine tail gas purifier is applied to the engine-driven equipment of various dependence, for example automobile, steamer, with engine-driven generator etc.Purpose is in order to respond environmental protection, and the harmful matter in the purifying engine tail gas is to reduce the proportion of motor exhaust to pollution of atmosphere.Existing purifier structure is extremely complicated, the cost height, and the actual life of cleaning of off-gas is not long, and it is all right promptly to use the initial stage effect, but service time, long then purifying effect was difficult to have guaranteed.
The objective of the invention is to overcome prior art not enough and provide a kind of simple and reasonable, cost is low, ideal purification effect, effectively purify long self-suction combustion-promoting purifier for tail gas of engine of life-span.
The present invention adopts following proposal to realize: motor exhaust is isolated light combustible gas from the tail gas import by fixing blade, and light combustible gas is got back to motor work by combustion again by light combustible gas collection Taper Pipe from recovery tube.Remaining tail gas is mixed into the mixed combustion of combustion Taper Pipe through spraying the acceleration of Taper Pipe with replenish the fresh air that sucks the pipe from fresh air, discharges from the tail gas exhaust port then, reaches purifying effect.
The invention will be further elaborated below in conjunction with accompanying drawing 1 and embodiment:
Accompanying drawing 1 is the system architecture schematic representation of the embodiment of the invention, comprising tail gas import (1) is arranged; Fixedly vane (2), light combustible gas are collected Taper Pipe (3), light combustible gas recovery tube (4), spray Taper Pipe (5), the additional pipe of fresh air (6), are mixed combustion Taper Pipe (7), tail gas exhaust port (8).
At first, when motor exhaust enters by fixing vane (2) from the tail gas import (1) of plugging into engine exhaust, form eddy airstream and isolate light combustible gas, light combustible gas is collected Taper Pipe (3) by light combustible gas and is collected, and reclaims by the light combustible gas recovery tube (4) that links to each other with engine suction manifold then and sends the engine combustion acting back to.Remaining high-temperature tail gas continues to enter injection Taper Pipe (5) and carries out accelerating jetting, be mixed into combustion Taper Pipe (7) with the fresh air that replenishes pipe (6) suction from fresh air simultaneously and mix combustion, after the flammable harmful gas perfect combustion with remnants, discharge by the tail gas exhaust port (8) that joins with motor deutomerite outlet pipe, thereby reach the purpose of cleaning of off-gas.
In sum, the present invention has following advantage:
(1) valency is low: native system is simple in structure, and production technology is simple and easy, and cost is low.
(2) Acceptable life is long: native system is a complete mechanical structure, does not have chemistry
The catalysis medium are not subjected to the constraint of chemical catalysis media life; And native system does not have
Movable members, wear rate is low, and reparation property is strong.
(3) good purification: harmful inflammable gas has been carried out recycling and secondary combustion
Burn.
(4) energy-conservation: self-priming replenish air is combustion-supporting, does not consume the motor useful work, and flammable
The recycling of gas can improve the fuelling rate of motor.
(5) environmental protection: purify the harmful matter in the automobile tail, reduce vehicle exhaust to atmosphere
Pollute.
Claims (2)
1, self-suction combustion-promoting purifier for tail gas of engine is primarily characterized in that: described system includes tail gas import (1); Fixedly vane (2), light combustible gas are collected Taper Pipe (3), light combustible gas recovery tube (4), spray Taper Pipe (5), the additional pipe of fresh air (6), are mixed combustion Taper Pipe (7), tail gas exhaust port (8), air mixes combustion with self-priming entering in the system, inflammable gas is sent the engine combustion acting back to by collecting the recovery of Taper Pipe and recovery tube.
2, apparatus system as claimed in claim 1 is characterized in that: the self-priming of fresh air is by the tail gas suction of quickening through the injection Taper Pipe, and air also enters the mixed combustion of mixed combustion Taper Pipe after the mixing with it.
