A system for cracking alcohol into alcohol hydrogen as fuel

Abstract

A system for cracking alcohol into alcohol hydrogen as fuel. It consists of seven parts: alcohol supply device, heat absorbing device, cracking device, blending device, circuit control, display device and safety guarantee. The alcohol liquid passes through the cooling chamber, evaporates chamber, medium heat chamber, and high heat chamber absorb heat, and become alcohol vapor that reaches the upper limit of the optimal cracking temperature before entering the temperature-adjusted cracker with isothermal, dual temperature control, and four temperature monitoring, which is completely cracked into alcohol hydrogen while absorbing heat, alcohol Hydrogen can be purified into hydrogen and cooled, which is conducive to improving power. The blending device automatically controls the blending or full combustion of alcohol and hydrogen. The electrical appliances have two sets of automatic control and manual systems. When designing the system, safety measures are taken. When manufacturing the system, adopt With safety protection measures in place, the pressure, temperature, combustion conditions, alcohol conditions, and working conditions of the components of the entire system are all displayed on the display screen. Anyone can see any situation of the entire system at a glance. It will be discovered immediately and solved in time to ensure the safe use of the system.

Problems solved by technology

[0006]1. As we all know: the most important performance of vehicles, especially automobiles, is safety. In order to ensure safety, various instruments should be installed on automobiles so that drivers can Can know at a glance the operation of each part and link of the car, find minor problems, deal with them immediately, and avoid accidents, but the existing technology does not fully display the pressure, temperature and alcohol supply of each link in the alcohol-hydrogen combustion device The working conditions of the actuators such as pumps and solenoid valves, the alcohol-hydrogen combustion device has a small problem, there is no display, the driver does not know, and the small problem will gradually become a big problem, resulting in an accident. This is a safety hazard, as we all know: transportation The most important thing is safety. Vehicles with potential safety hazards cannot be used. If you use them reluctantly, if something goes wrong in the future, you must "compensate" and order "recall". At that time, huge economic losses will be caused

[0007]2. The hydrogen production device in the alcohol hydrogen combustion device is called "hydrogen generator" or "cracker", with a built-in catalyst. The prior art is in There is only one thermometer inside the catalyst, so it is impossible to know the temperature of the catalyst in front, back, left and right of the cracker far away from the thermometer. When the thermometer shows that the catalyst reaches the cracking temperature, the alcohol enters the cracking process. When the catalyst near the thermometer reaches the cracking temperature, the alcohol here can be cracked into alcohol hydrogen, but if the catalyst far away from the thermometer reaches the cracking temperature, the alcohol in other places will not know Whether it will be cracked into alcohol hydrogen, I don’t know how high the cracking rate is. Uncracked alcohol vapor enters the cylinder and will corrode the cylinder.

[0008]3. In the prior art cracker, the temperature difference between the head and the tail is relatively large. We have measured it during the test, and the temperature difference between the head and the tail is at 100°C when it is the largest As mentioned above, if the place with high temperature has reached the cracking temperature, the alcohol can be cracked into alcohol hydrogen, and perhaps the place with low temperature, the alcohol has not been cracked into alcohol hydrogen, resulting in a low cracking rate, and the uncracked alcohol vapor enters the cylinder, which will Corrosion cylinder, if the temperature is low, the cracking temperature has been reached, and the alcohol is cracked into alcohol hydrogen, maybe the catalyst has been burned out in the high temperature place

[0009] 4. The cracker of the prior art is that the alcohol liquid enters directly, and when the temperature of the catalyst measured by the thermometer reaches the cracking temperature, the computer directs the alcohol liquid to inject the cracking After that, the methanol vaporizes rapidly and absorbs a lot of heat, which reduces the temperature of the catalyst. If the alcohol vapor has not reached the cracking temperature, it will contact the catalyst with a lowered temperature. If the catalyst at this time has not reached the cracking temperature, the alcohol vapor will It will not be cracked into alcohol hydrogen, and it will leave the cracker. Therefore, the cracking rate is not high, and the uncracked methanol vapor enters the internal combustion engine, which will corrode the cylinder

[0010] 5. The cracker of the prior art is smaller, absorbs less heat, cracks less alcohol, and has a lower combustion rate. In order to increase the alcohol substitution rate, Alcohol vapor is commonly used for mixed combustion, and uncracked alcohol vapor enters the cylinder, which will corrode the cylinder

[0011] 6. In some existing technologies, when detecting the cracked gas, it is found that the proportion of hydrogen is less than 60%, and there is still uncracked alcohol vapor in the cracked gas , this is a comprehensive manifestation of the unreasonable design of the entire alcohol-hydrogen combustion device and the existence of many hidden dangers. It is necessary to check every parameter in the bench test and seriously improve it, otherwise, hidden dangers will inevitably lead to "recall"

[0012]7. The alcoholic hydrogen produced by the cracking of methanol under high temperature conditions is also very high temperature. After natural air cooling in the hydrogen storage cylinder, it is still very hot. The hydrogen alcohol in the cylinder is relatively thin, resulting in little power

[0020] At the same time, the volume content of carbon dioxide CO2 has reached 25%, and carbon dioxide CO2 is non-combustible Yes, entering the cylinder takes up space for nothing, which is not conducive to the improvement of power
