Example Embodiment

[0040] See Figure 1 and Figure 2 , an embodiment of the present invention provides an alumina ceramic hollow brick thermal storage heater for the regenerative body, is a plurality of positive hexagonal heat storage blocks and side blocks formed by the heat storage block cut to assemble a cylindrical structure.

[0041] Among them, the heat storage blocks in each layer of the regenerative body are arranged in a circumferential direction with the central regenerative block as the center, and the missing blocks between the outer sides of the outermost heat storage blocks are filled by the side blocks. Specifically, the regenerative body is composed of an m-ring regenerative block and a circle of edge blocks in the radial direction. Usually, the first circle, that is, the center of the regenerative body, is composed of 1 regenerative block, and the second circle is composed of 6 × 1 regenerative block, which are spliced radially on the outside of the six faces of the central regenera...

Abstract

The invention provides a heat accumulator for an aluminum oxide ceramic hollow brick heat accumulation heater. The heat accumulator is of a cylindrical structure formed by assembling a plurality of regular hexagonal prism heat accumulation blocks and edge blocks formed by cutting the heat accumulation blocks. Airflow through holes are axially formed in the heat storage block, and the airflow through holes are formed in the cross section of the heat storage block in an equilateral triangle mode; the heat storage blocks in each layer of the heat storage body are sequentially arranged in the circumferential direction with the center heat storage block as the center, and the missing blocks between the outer sides of the heat storage blocks on the outermost periphery are filled with the edge blocks. The airflow through holes of the upper-layer heat storage blocks and the lower-layer heat storage blocks are correspondingly communicated; and the airflow through holes of the upper-layer side blocks and the lower-layer side blocks are correspondingly communicated. The invention further provides a preparation method of the heat accumulator for the aluminum oxide ceramic hollow brick heat accumulation heater. According to the heat accumulator for the aluminum oxide ceramic hollow brick heat accumulation heater and the preparation method of the heat accumulator, the ceramic defect of the heat accumulator is low, and the thermal shock resistance is high.

Description

technical field [0001] The invention relates to the technical field of heaters, in particular to a regenerator for an alumina ceramic hollow brick regenerator heater and a preparation method thereof. Background technique [0002] The alumina hollow brick heat storage heater is a high-temperature pure air heating device, and the temperature of the heated airflow can reach the order of 2000K. Alumina hollow brick heat storage heater is mainly composed of alumina regenerator, refractory cylinder, heat insulation cylinder, metal shell and other components. Among them, the alumina hollow brick regenerator is the core component of its energy storage and heating airflow. [0003] At present, since the alumina hollow brick regenerator is prone to ceramic defects in the preparation process, the high-temperature alumina regenerator brick is easily damaged due to the impact of extremely strong high-pressure cold air flow during use. Moreover, in order to meet the requirements for the...
