Description
The utility model relates to a kind of Purification of IC Exhaustive Gas sound-attenuating system: it comprises the silencing apparatus that links with exhaust manifold for internal combustion engine and draw a part of gas from gas exhaust piping, and with the air mixing of proper proportion, send back to the device of combustion chambers of internal combustion engines.
A kind of gas purge system of passing through filtration system that is specially adapted to internal-combustion engine is disclosed in the Chinese patent 87100805.In order to reduce the pollution of automobile emission to air, the formation of this technological scheme is: on gas exhaust manifold, be connected in series the intermediate expansion chamber successively, expansion chamber and silencing apparatus, with return line that expansion chamber is connected on, a series of filtrating equipments have been installed completely, decompressor by the automatic work of electrical equipment control, from expansion chamber 60% to 90% effulent is sucked, and after filtration, with the air mixing of proper proportion after, send back to the firing chamber of internal-combustion engine.Its deficiency is: the cooling of exhaust mainly relies on the expansion chamber that is serially connected on the pipeline, promptly realizes by the expansion of effulent with pipeline.Because delivery temperature and oxygen concentration are the fundamental influence factors for the concentration of last institute hydrocarbon-containiproducts in the exhaust, and this scheme just lacks effective cooling method, add the expansion repeatedly of gas, so that for the hydrocarbon in the effulent provides suitable combustion condition, its result makes the inflammable gas that reclaims in the effulent reduce.In fact, also have in the prior art with thermoinsulation material, its objective is that the hydrocarbon that promotion is not fired burns away in silencing apparatus, to reduce the pollution of effulent to air to the technological scheme that silencing apparatus is incubated.
For this reason, the purpose of this utility model be to overcome above-mentioned deficiency of the prior art and provide a kind of can reduce effectively the engine exhaust thing to the pollution of air, reduce combustible substance in the effulent scaling loss, have the Purification of IC Exhaustive Gas sound-attenuating system of better energy-saving effect.
The purpose of this utility model can reach by following measure: this system has the device that makes gas exhaust piping or the cooling of its silencing apparatus.
The purpose of this utility model can also reach by following measure: described cooling unit is a water cooling plant.
And/or, cooling unit is an air cooling equipment.
And, on the silencing apparatus outer wall radiating fin is arranged, several rows of damping plate that is obliquely installed and circulation water channel are arranged in the silencing apparatus, the two is alternate shape along silencing apparatus and distributes, damping hole is arranged on the damping plate, the circulation water channel passes therebetween damping plate with the mistake water pipe and is connected with each other, its intake pipe is connected with water pump, return pipe is connected with water tank, in silencing apparatus, also has one by its inwall and damping plate, the mud chamber that filter plate surrounds, between last filter plate and the following filter plate is the filter chamber, an end of drawing the pipeline of effulent is fixed on the silencing apparatus and with the filter chamber and is connected, and a mouth of pipe of fixing three-way pipe links to each other on the other end and the air cleaner for internal combustion engine, and another mouth of pipe of three-way pipe is provided with the flow control valve that communicates with ambient air.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the integrally-built schematic representation of native system.
Fig. 2 is the enlarged view of silencing apparatus shown in Figure 1.
Fig. 3 is the sectional view along Fig. 2 " A-A " cutting plane.
The utility model is described in further detail below in conjunction with accompanying drawing:
Can understand the structure of native system with reference to each accompanying drawing, radiating fin ［ 16 ］ is arranged on the outer wall of silencing apparatus ［ 20 ］, several rows of damping plate that is obliquely installed ［ 8 ］ and circulation water channel ［ 18 ］ are arranged in the silencing apparatus ［ 20 ］, the two profile is identical and be alternate shape along silencing apparatus ［ 20 ］ and distribute, damping hole ［ 9 ］ is arranged on the damping plate ［ 8 ］, crossing water pipe ［ 17 ］ passes damping plate ［ 8 ］ the circulation water channel ［ 18 ］ that is positioned at before and after it is connected with each other, the intake pipe ［ 6 ］ of circulation water channel ［ 18 ］ is connected with water pump ［ 2 ］, return pipe ［ 7 ］ is connected with water tank ［ 1 ］ (can link to each other with upper tank or lower header), in silencing apparatus ［ 20 ］, also has one by its inwall and damping plate ［ 19 ］, the mud chamber that filter plate surrounds ［ 15 ］, a plug screw ［ 14 ］ of blocking pollutant exhaust hole is arranged at the bottom of silencing apparatus ［ 20 ］, be filter chamber ［ 13 ］ between last filter plate ［ 11 ］ and the following filter plate ［ 12 ］, an end of drawing the pipeline ［ 10 ］ of effulent is fixed on silencing apparatus ［ 20 ］ and upward and with filter chamber ［ 13 ］ is connected, the other end links to each other with the mouth of pipe that the air-strainer ［ 3 ］ of internal-combustion engine ［ 4 ］ is gone up fixing three-way pipe ［ 21 ］, and another mouth of pipe of three-way pipe ［ 21 ］ is provided with the flow control valve ［ 22 ］ that communicates with ambient air.If need further improve the cooling effect of gas exhaust piping, also can on outlet pipe ［ 5 ］, set up radiating fin.In fact, the internal-combustion engine less for power, that delivery temperature is lower is appointed a kind of in air-cooled of water intaking cold-peace, also can receive satisfied effect.
During fabrication, can adopt the method for welding that circulation water channel ［ 18 ］ and damping plate ［ 8 ］ are fixed in the silencing apparatus ［ 20 ］, the method that the two ends of mistake water pipe ［ 17 ］ also can be welded is connected with circulation water channel ［ 18 ］.
