Description

Snakelike alcohol cracker

The utility model relates to a kind of alcohols schizolysis hydrogen production plant, especially in the automobile to the hydrogen-generator of motor fueling.

Make fuel with gasoline or diesel oil, with the internal-combustion engine traffic tool such as automobile, train, aircraft, steamer of power, not only exhaust gas discharged pollutes the environment, and oil is a Limited resources, now day by day exhausted, in order to reduce the dependence of petroleum resources and to reduce of the pollution of exhaust gas discharged such as automobile to environment, relatively the method for reality be with alcohol be raw material by the device of fissioning after, fission into hydrogen, gasoline replacing or the burning of diesel oil IC engine supply.

With the material of carbon containing, after chemical reaction system alcohol has been ripe technology in factory, and coal and various organic substance all contain carbon.Many organic substance such as sugarcane bagasse, various vegetation all can be planted, and are stranded this, and alcoholic product is inexhaustible, nexhaustible resource, and the alcohol process heats under the effect of catalyzer, and fissible one-tenth hydrogen is fuel with hydrogen, and is free from environmental pollution.Mix burning with hydrogen and gasoline or diesel oil, can impel gasoline or diesel oil perfect combustion, significantly reduce of the pollution of its waste gas, and hydrogen is when internal combustion engine burns, the power of machine in " hydrogen is quick-fried " of generation can increase environment.Therefore hydrogen is very good fresh fuel, and existing is that example describes with the automobile, and pure hydrogen is as follows for the process of combustion: methanol pump is placed in the methanol tank bottom, and it is controlled by computer automatically for the instruction of alcohol amount by the driver.Methyl alcohol enters the fission device that is series on the gas exhaust piping through filter cleaner, heat absorption, gasification, fission into hydrogen by catalyzer, enter gas cylinder, via the driver send instruction by computer automatically the flow of control cut down and enter hydrogen-oxygen mixer, after air mixes by air fuel ratio, enter the hydrogen oil mixer of automobile carburetor bottom, enter internal-combustion engine.Chinese patent application CN1034248A (application number 88108905.2) discloses a kind of " pyrolysis reactor of alcohols ", and this reactor is connected on the engine exhaust pipeline, comprises the overheated portion of evaporation, and catalyzer is filled and three main parts of reacting part.It is characterized in that these three parts are loaded in the reactor shell, between a upper face plate and lower face plate, be fixed with vaporization chamber and reaction tube, be packaged with catalyzer in the reaction tube and fill, the hot cell of crossing that is positioned between lower face plate and reactor shell makes vaporization chamber communicate with reaction tube.Institute's calorific requirement is all provided by engine exhaust heat, and the oxygen-rich gas of generation mixes the back supply engine with atomization gas.Chinese patent application CN1118407A (application number 94116320.2) discloses a kind of " engine producing hydrogen with remainder heat ", directly adorn a hydrogen generator on original waste pipe road, the exhaust silencer and the pyrolysis reactor of alcohols of motor are combined into one, pyrolysis reactor of alcohols is by the hot cell of gasifying, and cross over pipe and reaction chamber are formed the U-shaped structure.

Above principle and pure hydrogen are early well known for the combustion process, does but why pure hydrogen fail to come into operation for combustion always? main cause is: 1, will fission into hydrogen through domestic and international a large amount of evidence methyl alcohol fully under the effect of catalyzer, enough catalyzer pipeline length must be arranged, and such long tube can't be placed on the automobile exhaust pipeline.2, can be folded into coiler to long tube, can be installed on the automobile exhaust pipeline, but catalyzer extremely difficulty pack in the coiler, take out dead catalyst and change more difficultly, it is passable to do experiment, but can not popularize use.3, the pipeline of dress catalyzer is shortened, catalyzer can be packed into, and the fission device also can be contained on the gas exhaust piping of automobile.After coming into operation, originally effect is fine, has realized pure hydrogen for combustion, and automobile power increases, exhaust emission pollution reduces, but because the pipeline of dress catalyzer falls short of, methyl alcohol can not get fissioning fully, after remaining methyl alcohol enters internal-combustion engine, will inevitably corrode internal-combustion engine, and making deterioration of lubricant, time one length will inevitably be damaged internal-combustion engine and accidents happened because of lubricating oil is rotten.

The purpose of this utility model is intended to overcome the deficiencies in the prior art, provides a kind of catalyzer to be easy to change, and has the alcohol cracker of snakelike subdivision structure.

Snakelike alcohol cracker shell described in the utility model is connected on the automobile engine exhaust pipe, one end of housing has alcohol intaking pipe, in housing, be snakelike, the catalyst unit lower end connects with snakelike alcohol intaking pipe is movable, catalyst filling in the pipeline of middle part, the top is a sealable opening, connect by lower channel between the catalyst unit, the other end of housing have be connected with catalyst unit go out the hydrogen pipe.

Pyrolysis apparatus described in the utility model is together in series straight tube dexterously, form serpentine channel, can guarantee that methyl alcohol all fissions into hydrogen in sufficiently long snakelike road, the opening at its catalyst unit top can hold more catalyst changeout of ground again very much, because movable connection the between the catalyst unit, after the first module catalyst ageing, can successively second, third unit be become first module, and add new catalyst unit in the back, and catalyzer is fully used, can reach good lytic effect again.

Accompanying drawing is the utility model structural representation

Below in conjunction with accompanying drawing the utility model is described further, but is not limited to accompanying drawing.

Above-mentioned accompanying drawing can be as an embodiment of the present utility model.

The pyrolysis apparatus shell is connected on the automobile exhaust pipe (9), with the core pipe heating of the waste heat of internal-combustion engine combustion gas with pyrolysis apparatus, methyl alcohol enters heating in the coiler, gasification from the alcohol intaking pipe (1) of pyrolysis apparatus, and its temperature is controlled between D (the minimum control temperature of methanol decomposition) and the G (catalyzer is not because of the highest overheated and rotten control temperature) by electronic device.Methanol gas by the chamber, lower-left (2) of catalyst elements, enter catalyzer pipeline (3), be cracked into hydrogen, reach in the unit upper cavity (4), uncracked methyl alcohol enters catalyst tube (5) together with hydrogen, continue cracking, afterwards, enter chamber, bottom right, unit (6), also uncracked methyl alcohol enters next unit continuation cracking unit number through connecting tube (7) together with hydrogen and is determined by the dissociated methanol amount, guarantee to also have certain affluence amount after methyl alcohol all is cracked into hydrogen, after methyl alcohol all is cracked into hydrogen, enter gas cylinder by going out hydrogen pipe (8).Catalyzer is impelling methyl alcohol to fission into progressively aging, inefficacy in the process of hydrogen, the methyl alcohol of the cracking catalyst of first module is maximum, thereby it is aging also the fastest, after treating catalyzer total failure, first module is taken off, become the first module centre to second yuan and add a new unit at last, like this, catalyzer can be fully used.
