Abstract
The utility model provides a novel low-emission diesel traction transportation vehicle, comprising a diesel engine. An exhaust port of the diesel engine is connected with an inlet end of a precious metal purifier via a metal pipe; an outlet end of the precious metal purifier is connected with an inlet end of a water tank; and an outlet end of the water tank is connected with an exhaust pipe. The novel low-emission diesel traction transportation vehicle disclosed by the utility model is favorable for solving a pollution problem of an internal-combustion diesel engine in tunnels, can be used for eliminating 90 percent of noxious substances and particulate matters in the diesel engine so as to provide a cleaner environment for long and large tunnels during construction and has a very good practical value.
Description
Technical field
The utility model belongs to diesel traction transport vehicle technical field, is specifically related to a kind of novel low emission diesel traction transport vehicle, is mainly used in the frequent occasion of using internal combustion transport vehicle construction operation in the not only long but also big tunnel.
Background technique
Development along with China's water conservancy and hydropower, expressway, railway; Introduced a lot of TBM mechanized, and these operations all are long and big tunnel, the hauling operation amount in its construction is very big; It is essential wherein to draw transport vehicle; And the internal combustion transport vehicle has remarkable advantages than storage battery traction transport vehicle, but its heavily contaminated is puzzlement workmen's a difficult problem always, therefore is necessary to improve.
The model utility content
The technical problem that the utility model solves: a kind of novel low emission diesel traction transport vehicle is provided; At the diesel exhaust gas mouth precious metal purifier is set; Precious metal purifier outlet end connects water tank, water tank and outlet pipe platoon, and the tail gas after outlet pipe will purify enters in the atmosphere.
The technological scheme that the utility model adopts: novel low emission diesel traction transport vehicle; Comprise DENG; The relief opening of said DENG connects the entry end of precious metal purifier through metallic conduit; The outlet end of said precious metal purifier connects the entry end of water tank, and the outlet end of said water tank connects outlet pipe.
Further, the length of said metallic conduit is less than 300mm.
Further, said metallic conduit is provided with and measures exhaust pressure and the pressure gauge that uses a period of time final vacuum pressure when installing.
Further, said water tank is the passivation stainless steel water tank.
The utility model has compared with prior art solved the pollution problem of internal combustion DENG in the tunnel to a great extent; This device can eliminate 90% harmful substance and particulate matter in the DENG; Comparatively clean environment is provided for not only long but also big tunnel when construction, has good use value.
Description of drawings
Fig. 1 is the utility model structural principle schematic representation.
Embodiment
A kind of embodiment of the utility model is described below in conjunction with accompanying drawing 1.
Novel low emission diesel traction transport vehicle; Comprise DENG 1; The relief opening of said DENG 1 is to guarantee depuration quality through the entry end of metallic conduit 2 connection precious metal purifiers 3, and the length of metallic conduit 2 is preferably less than 300mm; Exhaust pressure and use a period of time final vacuum pressure when installing for measuring; Also be provided with pressure gauge at metallic conduit 2, the outlet end of said precious metal purifier 3 connects the entry end of passivation stainless steel water tank 4, and the outlet end of said passivation stainless steel water tank 4 connects outlet pipe 5.
Principle and structure: this traction transport vehicle at first adopts low emission to reach the DENG 1 of Europe five standards, and the exhaust emission source of DENG 1 is mainly carbon monoxide (CO), hydrocarbon (HC), black smoke particulate matter (DPM), sulfur dioxide (SO
2), oxynitrides (NO
X), at the about 300 millimeters places of exhaust end precious metal purifier 3 is housed then, purify carbon monoxide (CO), hydrocarbon (HC), sulfur dioxide (SO
2); Through transpassivation stainless steel water tank 4, purify black smoke particulate matter (DPM) and oxynitrides (NO again
X), like this, the harmful matter that enters atmosphere through outlet pipe 5 is just seldom.
The shell of precious metal purifier 3 is to process with stainless steel; In the precious metal core body is arranged and is coated with catalyzer (in course of reaction, do not consume its composition, so not frequent change core body), the material of making core body is that the folded wrinkle of resistant to elevated temperatures precious metal thin slice is formed; Some such thin slices are encapsulated by stainless steel cylinder and stainless steel retaining ring; Form the honeycomb complex structure, the waste gas fluid is flowed through on it to greatest extent and is fully contacted with catalyzer, and changes into innocuous gas to greatest extent; Water tank 4 is processed with the stainless steel material of passivation, corrodes with the nitric acid that prevents to generate and its generation chemical reaction, innerly makes cellular many interlayers with stainless steel material, to guarantee fully contacting and reacting of gas and water; Precious metal purifier 3 directly is connected through metal tubes 2 with DENG 1; And prevent gas leakage, a back pressure hole is set, exhaust pressure and the pressure after use a period of time when installing to measure on this pipeline; If pressure difference reaches 1.5bar, will clear up purifier; The distance of the two is approaching as much as possible, and because of when temperature is high more, the efficient of catalyzer performance is big more; The gas that precious metal purifier 3 is discharged and passivation stainless steel water tank 4 are connected through metal tubes; The pipeline that inserts water tank does not contact the water surface; Suck-back water is in precious metal purifier 3 when preventing to cool off, and can directly enter in the atmosphere through the gas of transpassivation stainless steel water tank 4.This device can eliminate 90% harmful other and particulate matter in the DENG.
The foregoing description, just the preferred embodiment of the utility model is not to be used for limiting the utility model practical range, so all equivalences of being done with the said content of the utility model claim change, all should be included within the utility model claim scope.
