The present invention is relevant a kind of tubular catalyst purifying apparatus for locomotive, refers to a kind of purification plant of the exhaust pollution that just can effectively purify locomotive and produced with simple structure and cheap manufacture cost especially.
As everyone knows, owing to contain pollutants such as a large amount of HC and CO in the waste gas that locomotive is discharged, be the main cause of atmospheric pollution in fact, for the continuation that prevents atmospheric pollution worsens, Taiwan environmental protection unit formulates the locomotive first phase and second phase air pollutant emission standard then.Wherein according to being limited to CH+NO=3.0g/km on the second phase statutory standard regulation pollutant, CO=4.5g/km, while new model check must be through durability experiment more than 6000 kilometers, and the side meet standard.
Solving locomotive now pollutes the most effective and convenient feasible method is and installs Catalytic Converter additional, the applied technology of general known Catalytic Converter can be divided into two kinds haply, be respectively the coating catalyst of cellular Catalytic Converter and outlet pipe internal face and component surface etc., below only give simple declaration with regard to the relevant application technology of above two kinds of patterns:
1. cellular Catalytic Converter:
Locomotive then gives improvement with the application technology of cellular Catalytic Converter, the mature technology of all continuing to use automobile haply, to meet the use of locomotive.This The Application of Technology is respectively Catalytic Converter to be connected in the side end in the outlet pipe expansion chamber and the half-way of locomotive outlet pipe.
2. the coating catalyst of outlet pipe internal face and component surface:
The application of this technology is with the surface of the internal face and the member in the outlet pipe of outlet pipe, is formed with ceramic coating layer, and is covered with catalyst layer on this pottery coating layer.
Above-mentioned known catalyst device, lie in exhaust after the engine combustion by the catalyst monomer cellular tissue or when the inner surface of outlet pipe of exhaust process or tubular type monomer, quicken the oxidation reaction of locomotive exhaust contaminant by means of being coated on the activity that goes up noble metal in the inner surface of catalyst monomer or outlet pipe, to reach the purpose of purification.But, show from the data result of above-mentioned known technology, though have certain degree for the improvement ability of pollution, but still following shortcoming is arranged:
(1) cost of general cellular Catalytic Converter is formed; can be divided into three haply; be respectively noble metal, manufacturing expenses and monomer price; and the price of monomer; owing to be subjected to monomer material, make difficulty (and being controlled in minority foreign vendor) and patent protection etc.; often account for 1/3 to 1/2 of overall cost, make cellular Catalytic Converter hold at high price, embarrass general popular acceptance.
(2) the coating catalyst of outlet pipe internal face and component surface, this technology are on practice, and the coupling of its outlet pipe and this technology will seem and quite difficulty cause the inconvenience of device catalyst in outlet pipe.
So as from the foregoing, above-mentioned various Catalytic Converter are implemented obviously still to have very big inconvenience and disappearance, and can wait to be improved in the running in reality.
Main purpose of the present invention provide a kind of produce dual flow-disturbing effect, with increase that exhaust contacts with the catalyst monomer catalyst purifying apparatus.
The invention provides the purification plant of a kind of locomotive, be suitable for being arranged in the expansion chamber of locomotive diffusing cone pipe draining tracheae with exhaust pollution; This purification plant is material with the corrosion resistant plate, and this material surface punching out is become the circular hole of a plurality of skies or tool flange, after again it is rolled into two oviducts, one is reducing pipe, another then is an increaser, the portlet that connects two pipes constitutes an independent monomer together, and inner and outer surface all is coated with the noble metal that one deck can be used as active matter on this monomer, and outlet pipe inside then is fixed in to use in two outer ends of this monomer.
Utilization is according to device of the present invention, because exhaust is introduced into reducing pipe, and then enters increaser, makes exhaust produce the effect of dual flow-disturbing.Increase the chance that waste gas contacts with monomer, join the active matter with the monomer surface-coated, can reach preferable purifying exhaust gas effect.This device is made container, and is cheap and be easily mounted in the outlet pipe.
For making the public for purpose of the present invention, feature and effect, have and further understand and approval, conjunction with figs. is described in detail as follows now:
