Dust removal / heat conversion integrated device and method based on gradient honeycomb body and three-dimensional rib tube

摘要

The present invention provides a dust removal / heat conversion integrated device and method based on a gradient honeycomb body and a three-dimensional rib tube, and belongs to the field of industrial energy saving / environmental protection technology. The device is composed of a composite gradient hole metal honeycomb body, a metal support, and a three-dimensional inner / outer rib tube in order from the outside to the inside. The composite gradient hole metal honeycomb body is processed and created by heat-resistant metal thread, the porosity changes to a gradient in a horizontal and vertical direction, and the honeycomb type filtration heat storage / heat conversion body is formed by stacking and accumulating. As for the three-dimensional inner / outer rib tube, a three-dimensional rib flat plate chamber or a three-dimensional inner / outer rib tube having a three-dimensional discrete rib structure is processed on the surface of the heat conversion chamber or the heat conversion tube. The device can breakthrough and continuously remove dust and heat storage / heat exchange with high content at a high temperature of 600 ° C-1200 ° C, and can efficiently purify and stabilize heat storage / heat conversion. It has advantages such as continuous operation and long life, and has a residual heat recovery efficiency of 70% or more and a dust removal efficiency of 99% or more. [Selection diagram] Fig. 1
