Minitype swirl premixed regenerative catalytic combustion reactor

Abstract

The invention discloses a minitype swirl premixed regenerative catalytic combustion reactor. The catalytic combustion reactor comprises an external cylinder, an upper panel, a porous panel and a U-shaped panel, wherein the upper panel and the U-shaped panel form a cavity with the rectangular cross section; the porous panel is arranged at one end of the cavity; the cavity is formed in the external cylinder; four upper regenerative columns, which vertically extend into the cavity downwards, are arranged on the upper panel; six lower regenerative columns vertically arranged upwards and staggered with the upper regenerative columns are arranged on a lower bottom plate of the U-shaped panel; two air inlets and two fuel gas inlets are formed in the external cylinder in the tangential direction of the circumference; an outwards protruded air outlet is formed in the center of a left side panel. The external cylinder, the porous panel and the cavity are combined to form an airflow premixed passage to avoid the direct contact between the high temperature wall surface of a combustion chamber and the environment and reduce the heat loss; meanwhile, the high temperature wall surface of the cavity can preheat the premixed gas to increase the initial temperature of the premixed gas and reduce the ignition difficulty of the gas.

Description

technical field [0001] The invention relates to a reactor suitable for gas catalytic combustion, in particular to a swirl premixed regenerative miniature catalytic combustion reactor. Background technique [0002] The utilization of energy generated by fuel combustion is the most widely used energy utilization method in production and life. With the development of science and technology, the application of micro-mechanical systems has been paid more and more attention by scientists. The micro-scale burners currently studied are generally below 1cm 3 occurs within the volume. Microscale burners have the advantages of low cost, longer shelf life, more stable voltage, high energy density and easy refueling. The research on micro-scale burners hopes to solve the problem of long-term stable power supply for portable electronic devices, but in addition to this application, micro-scale combustion has another important application field, that is, the application in future nationa...

AI Technical Summary

Problems solved by technology

But at this stage, micro-scale burners still have the following deficiencies: first, serious heat dissipation; second, insufficient gas premixing; third, due to the small size of the burner, short residence time, and too small reaction area, the reaction cannot fully occur The efficiency is too low; 4. The structure of the reactor is complex and the processing is too difficult
