Abstract
The invention provides a diesel-powered motor vehicle tail gas purification device. A tail gas cooling system is formed by a heat-dissipating fin pipe and a heat-dissipating fan. According to the purpose, the emission temperature of tail gas of a diesel engine is lowered below 100 DEG C from 500 DEG C, the tail gas with the lowered temperature enters a tail gas spray pipe distribution cabinet in an adhesive oil tank, and a plurality of tail gas spray pipes spray gas to the surface of adhesive oil. By the utilization of the physical property of the adhesive oil, soot particulate matters in the tail gas can be collected, the purification effect is 95-100%, effective control over air environmental pollution is strengthened, and body health of people can be guaranteed easily.
Description
One, technical field
Exhaust gas purifying device for diesel engine driven vehicle, is a kind of for administering purifying tail gas of diesel vehicles, the novel external purification technology of carbon soot particles pollutant.
Two, background technique
Diesel engine vent gas carbon soot particles pollutant control external purification measure up till now, use have catchers such as integrated type ceramic honeycomb catcher, wire gaze catcher, braided fiber catcher, ceramic fiber, foamed ceramics.The catcher of above-mentioned these several different structures all exists a common technology shortcoming, is exactly in vent systems, to install after catcher, will make the exhaust back pressure of motor improve, and power declines.The particulate matter depositing on catcher material is more, and exhaust back pressure is higher.Therefore must regularly remove particulate on cake filtration material, removing and being deposited on particulate process on filtering material is trap regeneration.When engine work, the delivery temperature of motor is 200 ℃-500 ℃, and the burning-point of particulate is generally 500 ℃-600 ℃, relies on engine exhaust to be difficult to make trap regeneration.Make trap regeneration just must reduce the burning-point of particulate or improve delivery temperature.Its method first is on catcher material, to be coated with palladium platinum-rhodium catalyst coating, can reduce the burning-point of particulate.The secondth, adopt electric heating afterburning and another to use the method for the burner heating afterburning of oil inflame.When the gas temperature of catcher surpasses 650 ℃, the core temperature of catcher will surpass the tolerance limit of material.Will there is melting loss be full of cracks in catcher, cause catcher can not reach the catcher purifying effect of expection.(cited paper: publishing house of Beijing Institute of Technology publishes, Du's delivery is far away, solution is built light and is compiled " engine exhaust and purification " (in July, 2007, front page was the 153rd page-160 pages)).
Three, summary of the invention
Exhaust gas purifying device for diesel engine driven vehicle, be the radiation system consisting of engine exhaust port connecting tube, wing heat dissipating pipe, cooling fan, intermediate connection tube, its objective is can be by diesel engine exhaust emission temperature from 500 ℃ of cooling systems of being down to below 100 ℃.
By adhering to oily oil box, adhere to oil filler, tail gas jet pipe distributor case, tail gas jet pipe, adhesion oil, soot particulate precipitation collection cups, hot-air damper, adhere to oil cooling pipe, adhere to oil temperature cooling fan, the soot particulate cleaning system that after purifying, exhaust emission tube forms.
Beneficial effect:
Adopt technique scheme just soot particulate in tail gas can be purified, purifying effect reaches 95-100%, this to reinforcement air environmental pollution effectively administer, ensure people healthy be favourable.
In addition, by diesel car, travel after tens thousand of kilometers, (this standard is formulated rules by relevant functional department of country), must adhere to the oily processing and utilization specialized agency (place) that reclaims to specifying, reclaim the soot particulate that adheres to oil and precipitated collection thereof, and adopt the separated processing technique of advanced science, making to adhere to oil can reuse, the black additive that soot particulate can be used as rubber product, ink product again, avoids producing secondary time natural disposition air environmental pollution problem.

Five, specific embodiments
By engine exhaust port connecting tube 1, tail gas is imported in wing heat dissipating pipe 2, and it is cooling by cooling fan 3, to carry out forced heat radiation, exhaust temperature is dropped to below 100 ℃ from 500 ℃, the tail gas of being lowered the temperature forms tail gas cooling systems through intermediate connection tube 4.
By adhering to oily oil box 5, adhere to oil filler 6, tail gas jet pipe distributor case 7, tail gas jet pipe 8, hot blast gear pipe 9, adhere to oil cooling pipe 10, cooled tail gas sprayed on the pasta that adheres to oil 11, soot particulate precipitates collection cups 12, adheres to oil temperature cooling fan 13, and after purification, exhaust emission tube 14 forms oily, the adhesion collection and purification system that adheres to.Utilize to adhere to oily physical property, just can be by the carbon soot particles collection and purification in tail gas, purifying effect reaches 95-100%, this effectively administers reinforcement air environmental pollution, ensure people healthy be favourable.
