Abstract

The utility model relates to a waste gas recovering and utilizing device for an engine, which is composed of a silencing and cooling device, an air sucking device, a water gas positioning and releasing device, a mixing device, a gas exhaust pipe, and a filter screen. In the utility model, a closed loop is formed from a water gas exhaust port of the engine to an air cleaner, and namely waste gas is cooled, air is sucked inside, the mixing and the filtering are carried out, etc.; the waste gas which goes into the air cleaner of the engine can be reutilized. With the adoption of the utility model, the fuel can be saved, the power of the engine can be improved, and the effect that the air pollution caused by the exhaust of the waste gas can be avoided is obvious.

Description

The engine exhaust recycle device

The utility model belongs to the engine exhaust mechanism technical field.

From the operation of known motor fuel must be arranged, simultaneously in service must have a distribution process and and igniting process.These two processes are all finished by mechanical device and circuit structure.But because there is imperfect combustion fuel in the influence of the factors such as the time difference of precision, wearing and tearing, corrosion and the circuit of mechanical structure in the waste gas that the motor operation is discharged.Therefore not only waste fuel but also be directed at the underpower of motor, waste gas enters the pollution that can cause environment in the air simultaneously.

The purpose of this utility model relates to the circulation means that the waste gas of motor is recycled, and has both made full use of fuel, can control toxic emission again in air, avoids causing environmental pollution.

The utility model is that the waste gas of motor is discharged via two-stage or multistage noise elimination waste gas cooling device, two-stage or multi-staged air suck dilution, waste gas location releasing device, through entering engine air filter after the first road filter screen and two-stage or multistage waste gas and the Air mixing, utilize again.When the waste gas of motor entered silencing apparatus, temperature was higher, so this device is equipped with many cooling tubes in silencing apparatus, stretch out outside the silencing apparatus at two of cooling tube, and horn mouth is arranged, and be convenient to suck more air and eliminate sound and the flow velocity of acceleration air, reach better cooling.The cooling device structure of multistage silencing apparatus is the same.Waste gas after two-stage or the multistage cooling sucks air mix facilities through the air of two-stage or multistage breeches pipe shape again, with exhaust gas dilution, it is to form several angle by two breeches pipes and outlet pipe that described breeches pipe shape air sucks air mix facilities, the breeches pipe mouth forward, the affixed and connection of breeches pipe rear end and outlet pipe.The air that the breeches pipe mouth enters dilutes waste gas in outlet pipe.A waste gas release positioning device is arranged in the middle of the two-stage air suction device, and it is that white waste gas discharges location cylinder that described waste gas discharges positioning device, and waste gas discharges cover and steel connection in garden is formed.It is a funnel shaped garden tube that waste gas discharges location cylinder, big mouthful of funnel forward, funnel osculum and outlet pipe are communicated with affixed, the centre (in the funnel) that waste gas discharges location cylinder has the cup-shaped waste gas in garden to discharge cover; Garden cup traverse, bottom be towards the microcephaly of funnel, rim of a cup forward, a lot of holes are arranged at a last week of cup and bottom, it is affixed that rim of a cup and outlet pipe pass through the garden steel, its place of connecing is all in waste gas release location cylinder.Behind the air suction device of the second level, first order filter screen is arranged, waste gas and air enter in the mixer through filter screen.Described mixer is by one section pipe thicker than outlet pipe, on its stage casing wall many air inlet holes is arranged, and there is hybrid network inside, mixer two, and this net is that the garden steel is welded in and forms net on the tube wall.By the second road filter screen is arranged behind the mixer, connect engine air filter in the filter screen back, many air inlet holes are arranged on the wall of air-strainer.

The utility model effect is conspicuous, because this device forms a closed loop, has therefore controlled toxic emission in air, has avoided the pollution of environment.Simultaneously because the recycling of waste gas, so the power of fuel saving and raising motor, therefore this device accelerates exhaust velocity owing to adopt waste gas to lower the temperature and the continuous fresh air that sucks, thereby reach reduction noise and atomizing and be in the optimum state, help full combustion of fuel.

Accompanying drawings:

Accompanying drawing 1 is the sectional view of two-stage noise elimination waste gas cooling device, 1 is outlet pipe among the figure, its front end connects the outlet port of motor, the rear end is connected with silencing apparatus 2, four cooling tubes 3 are arranged in the silencing apparatus 2, there is horn mouth at two of cooling tube 3, is convenient to enter air and exhausting air, quickens cooling and reduces noise.The 4th, outlet pipe, this pipe connects between first order silencing apparatus 2 and the second level silencing apparatus 6.The 5th, four cooling tubes in the second level silencing apparatus 6, stretch out at its two horn mouth outside the silencing apparatus 6.The 7th, outlet pipe.
