Embodiment Construction

[0007] As shown in Figure 1, a dividing plate 2 is provided in the middle of the case shell 1 of the present invention, and it is divided into two chambers by the case shell, namely the catalytic cracking reaction chamber 3 and the evaporation chamber 4, further designed to increase the size of the spacer on one side of the dividing plate 2. A partition 5, the distance between the two partitions 2 and 5 is ≥ 8mm, and the space between the two partitions 2 and 5 is filled with high temperature resistant material 6. Catalysts are installed in the reaction tubes, and the reaction tubes are vertically arranged in the chamber of the reaction bed. The lower part of the reaction tubes is equipped with a support net containing the catalyst. The support net is supported and fixed by the support net support. The gas storage chamber at the bottom of the reactor communicates with the hydrogen gas collection chamber on the upper part of the reactor, so that gaseous methanol is sucked into t...

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 [0001] The invention relates to a thermally insulated reactor for heating catalytic alcohol fuel by using the waste heat of an automobile muffler, especially a cracking device for vaporizing an alcohol fuel automobile muffler Background technique [0002] The most basic requirement of automobile fuel economizer is to realize energy saving and reduce pollution. Chinese patent: 95221264.1, titled: Catalytic cracking reaction on automobile fuel-saving device, discloses a catalytic cracking reactor on a fuel-saving and pollution-reducing device of an automobile, which includes a box shell and a catalytic cracking reaction set in the box shell The bed, evaporation chamber, steam storage chamber, hydrogen gas collection chamber and connecting pipes are provided with a partition in the middle of the case that can be divided into two chambers. Exhaust gas discharge pipe in the shape of a square product and a round horn: the catalytic cracking reaction bed is arrange...
