Problems solved by technology

[0005] The technical problems to be solved by the present invention are: 1. Improve the inhomogeneity of the temperature distribution of the traditional cylindrical tubular fixed bed reactor; 2. Improve the non-mixability of the internal flow distribution of the traditional tubular reactor; 3. Simplify the structure of the reactor and reduce the volume of the reaction system so that it can meet the needs of small-scale fixed hydrogen sources and mobile hydrogen sources; 4. Reduce the heat transfer resistance between reforming heat absorption and combustion heat release, and improve heat transfer Effect, reaction efficiency and reaction selectivity; 5. Improving the energy efficiency of the system

Embodiment Construction

[0049] Such as figure 1 , figure 2 and image 3 The shown microchannel plate-fin steam reforming hydrogen production reactor has a design power of 0.5KW. Micro-channel plate-fin steam reforming hydrogen production reactor, the main part is a micro-channel plate-fin structure, plus several welded heads, a total of five chambers, there are two combustion chambers 25, a reforming chamber 24 and two gasification chambers 23, and there are 0.4mm thick heat conducting plates 30 between the chambers. A reforming chamber 24 is sandwiched between two combustion chambers 25, and a gasification chamber 23 is located on the other side of the two combustion chambers. The hydrogen-rich gas and air undergo a catalytic combustion reaction in the combustion chamber 25, releasing a large amount of heat. Part of the heat is mostly transferred to the reforming chamber 24 and the two vaporization chambers 23 through the 0.4 mm heat conducting plate 30 . The raw material liquid first enters th...

Abstract

The invention discloses a microchannel plate-fin type water vapour reforming reactor for hydrogen production, wherein the main unit is a microchannel plate-fin structure, with a plurality of sealing heads through soldering, the reactor consists two combustion chambers, a reforming chamber and two gasification chambers, whereint he hydrogen-rich gas and air are subject to catalytic combustion reaction in the combustion chamber, discharging a vast amount of heat, which is transferred to the reforming chamber and the two gasfication chambers through a heat guide board, the raw material liquid first enters the two gasification chambers of the hydrogen production reactor, then enters the reforming chamber after being gasified, finally is reformed in the reforming chamber to obtain gaseous mixture of hydrogen gas that meets requirement.

Description

technical field [0001] The invention relates to the technical field of hydrogen production equipment, and relates to a microchannel plate-fin steam reforming hydrogen production reactor. The reforming hydrogen production reactor is the core of the entire hydrogen source system. The present invention especially relates to small-scale (1~1000NM 3 / hr) The fixed hydrogen source device and the vehicle-mounted mobile hydrogen source system provide a hydrogen source reactor for the fuel cell. Background technique [0002] Energy is the most important element in human economic activities. As we all know, the world today is facing many problems such as energy shortage, increasingly serious environmental pollution, and the greenhouse effect. In order to protect the environment on which human beings depend and sustain economic development, it is imminent to develop clean new and renewable energy. Many countries, especially many developed countries, have stepped up research and devel...
