Exhaust heat airborne follow type hydrogen production plant with built-in thermostat

Abstract

The waste-heat airborne follow device of the internal temperature-saving device relates to the hydrogen-preparing device of the power machine. The waste-heat airborne follow device which has compact structure, uniform heat transmission, stable hydrogen-preparing rate achieved from the splitting or reforming of the alcohol fuel using tail-gas as the head source and the internal temperature-saving device is developed against to the defects of unbalanced heat transmission, easily aging of catalyst, unable to load integral catalyst and fuel system structure and the complex control in the existing patents of ZL94116320.2 and CN1951718A. The adopted technology scheme is: the reactor 2 adopts the straight tube with large external diameter and thin catalyst. The evaporating superheater 16 has the tubular structure. The fuel system structure and the control method of the engine is simplified by the internal temperature-saving device 5.

Description

Technical field [0001] The invention relates to a hydrogen production device applied to power machinery, in particular to a waste heat airborne accompanying hydrogen production device applied to various mobile or fixed internal combustion engines and gas turbine engines. Background technique [0002] The hydrogen engine has the outstanding advantages of high energy conversion efficiency, good power performance and very little pollution. Hydrogen energy will become one of the ideal clean energy sources, and has attracted great attention and been widely used. However, the biggest obstacle to the widespread use of hydrogen energy lies in the difficulty of its storage and distribution. Its traditional industrial preparation methods cannot avoid this difficulty, and one of the effective ways to solve these problems is to generate hydrogen instantaneously through the catalytic conversion of suitable liquid fuels with high hydrogen content. Among the many possible liquid fuels, l...

Problems solved by technology

[0006] ZL94116320.2 and CN1951718A still use engine exhaust waste heat as the heat source for alcohol fuel cracking, which has the advantage of high thermal efficiency, and put the alcohol fuel gasification superheat and reactor tube in the same device, which has the advantage of taking up less space, but its existence Four deficiencies: one is that it can only be filled with granular catalysts, and the severe vibrations during locomotive driving make the catalysts easily rub against each other and become powdered; the other is that the catalysts are not heated uniformly, are easy to age, have a short service life, and high operating costs; The third is that the reaction process of alcohol fuel is short and uneven, the temperature of the catalyst layer is not easy to control, and the hydrogen production rate is unstable; the fourth is that external control means are needed to regulate the temperature of the cracker, which complicates the system structure and control
