Multilayer combined type miniature catalytic reforming reactor

Abstract

The invention discloses a multilayer combined type miniature catalytic reforming reactor comprising a seal cylinder, wherein the seal cylinder comprises an upper panel, a lower bottom plate and an outer cylinder; the upper panel is provided with a plurality of coaxial upper inner cylinders, the lower bottom plate is provided with coaxial lower inner cylinders with same amount with the upper innercylinders and staggered with the lower inner cylinders, the difference of heights of the upper inner cylinders and the lower inner cylinders is smaller than the distance from the upper panel to the lower bottom plate, and the lower inner cylinder at the innermost side extends out of the lower bottom plate; annular reaction channels are respectively formed between the outer cylinder and each upperinner cylinder and between each upper inner cylinder and each lower inner cylinder; and a plurality of air inlet pipes communicated with the annular reaction channels are arranged on the circumference of the outer cylinder along the tangential direction. In the invention, an inner cylinder, an outer cylinder and a spiral guide plate which are crossed on an upper bottom plate and a lower panel areformed into continuously ascending or descending channel so that liquid in the channel advances spirally along the channel to ensure that the movement path of reaction gas in a small space is greatlylengthened, the reaction time is prolonged, and the mixing quality of fuel gas and air is improved.

Description

technical field [0001] The invention relates to a reforming reactor suitable for gas reaction, in particular to a multilayer composite miniature catalytic reforming reactor. Background technique [0002] With the rapid development of micro-electro-mechanical systems (MEMS) technology, the influence of micro-device on many fields is becoming more and more obvious. The miniaturization of devices and the research of micro-systems have become an important topic of current research. Scholars and experts at home and abroad have done a lot of research and exploration on this topic, but there is still a certain gap from practical application. The micro burner is the core component of the MEMS, which has a significant impact on the performance of the MEMS. The micro burner has the advantages of small size and high energy density. In order to achieve high energy density, hydrocarbon fuel has become the first choice. However, the combustion of hydrocarbon fuels in the tiny space has e...
