Chromium-zirconium corundum honeycomb heat accumulator

Abstract

The invention discloses a chromium-zirconium corundum honeycomb heat accumulator, and belongs to the technical field of honeycomb heat accumulators. The chromium-zirconium corundum honeycomb heat accumulator comprises a frame body, heat accumulation plates abutting against one another are stacked in an inner cavity of the frame body, the heat accumulation plates abutting against one another form aheat accumulation main body, an upper connecting plate is detachably connected to the top of the frame body, a lower connecting plate is detachably connected to the bottom of the frame body, heat accumulation column fixing holes are evenly distributed in the heat accumulation plates, heat storage through hole columns are inserted into the heat storage column fixing holes, heat storage column positioning holes are formed in the upper connecting plate and the lower connecting plate correspondingly, and the heat storage column positioning holes are in one-to-one correspondence with the heat storage column fixing holes. According to the chromium-zirconium corundum honeycomb heat accumulator, each damaged and deformed part of the heat accumulator can be conveniently replaced, so that the service life of the whole heat accumulator is prolonged.

Description

technical field [0001] The invention relates to the technical field of honeycomb regenerators, in particular to a chromium-zirconium corundum-based honeycomb regenerator. Background technique [0002] Honeycomb ceramic regenerators are currently widely used in energy-saving technology for industrial thermal equipment. It can improve the efficiency of industrial thermal equipment, reduce energy consumption, increase production and improve quality. It is an important and effective means to solve energy and environmental problems. The cross-sectional pores of the honeycomb ceramic regenerator mainly have two pore structures of square and regular hexagon, and the channels are straight channel structures parallel to each other. This structure greatly reduces the resistance of the pores to flow through, and greatly improves the single-pore volume heat transfer efficiency of the heat storage body. The honeycomb ceramic regenerator has the characteristics of low thermal expansion, ...

AI Technical Summary

Problems solved by technology

This high-density chromium-zirconium corundum honeycomb heat storage body enables the heat storage through-hole column to be installed inside the fixing hole of the heat storage column, and the inside of the heat storage through-hole column is provided with regular hexagonal through holes to facilitate heat storage.” , but there are still defects. The main body of the honeycomb heat storage body is an integral structure. In actual use, the uniformity of its heating is different, resulting in differences in the service life of each part. When a single part is damaged, it needs to be replaced as a whole, resulting in a waste of resources
