Abstract
The muffler vaporizing and cracking device for alcohol fuel automobile is one alcohol fuel heating and catalyzing device utilizing the afterheat of automobile muffler. One partition board is increased in the catalyzing device to separate the casing into two chambers, catalytically cracking reaction chamber and evaporating chamber. Inside the casing, there are set catalytically cracking reaction bed, evaporating chamber, vapor storing chamber, hydrogen collecting chamber and connecting pipeline; and each of the chambers has belled inlet and the back of the casing is fitted with a belled tail gas exhaust pipe. Further, the partition board is constituted by two boards separated by over 8 mm and with heat resisting material filled in between. The cracking device can ensure the oil saving and pollution reducing performance of the oil saving and pollution reducing unit even in case of high exhaust pipe temperature of 350-500 deg.c.
Description
Technical field
The present invention relates to utilize the insulating reactor of the waste heat heatable catalytic alcohol fuel of automotive silencing device, especially a kind of cracking device of alcohol fuel automobile baffler vaporization
Background technique
Automotive fuel fuel economizer, its most basic requirement are to realize energy-conservation and the reduction blowdown.Chinese patent: 95221264.1, name is called: the catalyzer on the automobile fuel-economizing device is separated reaction, catalytic cracking reaction device on a kind of automobile fuel saving dirt reducing device is disclosed, it comprises one case shell, the catalytic cracking reaction bed that in the case shell, is provided with, vaporization chamber, vapor storing chamber, hydrogen collecting chamber and connecting tube, in the middle of this case shell, be provided with a dividing plate that can be divided into two chambers, the side that each chamber intake grill is rectangle amasss the circular horn shape, the tail gas discharging pipe of the long-pending circular horn shape in the side of being is equipped with in case shell rear end: it is indoor that described catalytic cracking reaction bed is arranged on one of them of case shell, this is indoor also to be equipped with a vapor storing chamber that is located at case shell bottom, one is installed in the holder net of vapor storing chamber top, one is located at the hydrogen collecting chamber at case shell top, and a hydrogen output tube interface, thermocouple and the sleeve pipe that connects temperature controlling instrument also is housed at case shell top.It is indoor that vaporization chamber is arranged on another of case shell, some heat exchanging tubes along the two-way perforation of steam flow are housed in the vaporization chamber, the vaporization chamber upper end hangs fixedly connected with methanol-water liquid ascending pipe, the vaporization chamber lower end connects with water conservancy diversion falling tube support fixation, in the lower end of methanol-water liquid ascending pipe spraying tube is installed vertically.The dividing plate that this technology adopted still comes with some shortcomings aspect heat insulation, as at hot weather, the flue gas leading exhaust gas temperature can reach 300 ℃ of-500 ℃ of high temperature, when the flue gas leading exhaust gas temperature surpasses 350 ℃, symptoms such as caking can appear in the catalysis particle in the reactor, thereby interrupt the vaporization lytic response of pure fuel.
Summary of the invention
Technical problem to be solved by this invention is: a kind of alcohol fuel automobile baffler vaporization cracking device that improves structure is provided, this vaporization cracking device is at hot weather, when the flue gas leading exhaust gas temperature surpasses 350 ℃, situations such as caking still can not take place in the catalysis particle in this vaporization cracking device, thereby the gasification reaction of this vaporization cracking device is carried out as usual.
The technical solution adopted for the present invention to solve the technical problems is: be provided with a dividing plate in the middle of the case shell, it is separated into two chambers with the case shell, is called catalytic cracking reaction chamber and vaporization chamber.The catalytic cracking reaction bed, vaporization chamber, vapor storing chamber, hydrogen collecting chamber and the connecting tube that in the case shell, are provided with; Be provided with a dividing plate that can be divided into two chambers in the middle of the described case shell, the side that each chamber intake grill is rectangle amass the circular horn shape, and the exhaust emission tube that the side of being amasss the circular horn shape is equipped with in case shell rear end; It is indoor that described catalytic cracking reaction bed is arranged on one of them of case shell. and further be designed to increase a dividing plate in a side of dividing plate, two clapboard spacings 〉=8mm are filled exotic material between two dividing plates.
The invention has the beneficial effects as follows: reaction chamber catalysis particle agglomeration problems when the present invention improves design and solved Tail Pipe Temperature height to 350 ℃-500 ℃ has guaranteed the performance of the oil saving and pollution reducing performance of oil saving and pollution reducing device.Simple and practical, have very strong practicability.
