Spherical regenerator

Abstract

The invention discloses a spherical regenerator comprising an upper sphere, a lower sphere and a platform segment. The platform segment is arranged between the upper sphere and the lower sphere. A central through hole is formed at the center of the upper sphere, the lower sphere and the platform segment, and is a conical through hole which is larger at the top and smaller at the bottom. The central through hole penetrates the upper sphere, the lower sphere and the platform segment along a central axis. The top of the upper sphere and the bottom of the lower sphere are provided with small planes. By the aid of the spherical regenerator, design defects are overcome, bonding between spheres can be reduced effectively, service life is prolonged, the number of sphere changing is decreased effectively, and operating efficiency is improved.

Description

technical field [0001] The invention relates to a heat storage device, in particular to a spherical heat storage body used on a hot blast stove or a heat storage device. Background technique [0002] At present, iron and steel chemical industry and other industries need many types of regenerators. Generally, checker bricks are used as regenerators for hot blast stoves, spherical regenerators are used for spherical hot blast stoves, and regenerative burners for regenerative heating furnaces in steel rolling systems Most of them also use spherical regenerators. Through years of follow-up research, it has been found that when spherical regenerators are completely used, due to the mutual extrusion between the balls and the insufficient thermal strength of the refractory material itself, coupled with many spherical The heat storage body is not mechanically pressed, and its own volume density is insufficient. After a period of use, the balls will stick to each other, resulting in ...

[0002] At present, iron and steel chemical industry and other industries need many types of regenerators. Generally, checker bricks are used as regenerators for hot blast stoves, spherical regenerators are used for spherical hot blast stoves, and regenerative burners for regenerative heating furnaces in steel rolling systems Most of them also use spherical regenerators. Through years of follow-up research, it has been found that when spherical regenerators are completely used, due to the mutual extrusion between the balls and the insufficient thermal strength of the refractory material itself, coupled with many spherical The heat storage body is not mechanically pressed, and its own volume density is insufficient. After a period of use, the balls will stick to each other, resulting in poor air permeability of the heat storage system, and the heat storage equipment has to be stopped. Changing the ball will not only affect production, but also cause frequent maintenance of equipment, resulting in increased production costs, thus affecting the economic benefits of the enterprise
