Abstract

The invention discloses a continuous-rotation heat accumulating type air preheater comprising a cylindrical heat accumulating body, wherein the upper part and the lower part of the cylindrical heat accumulating body are respectively provided with an upper part fan cover and a lower part fan cover which are respectively fixed on a stand body, and the cylindrical heat accumulating body is connectedwith a rotary driving device; the upper part fan cover is provided with a high-temperature flue gas inlet and a high-temperature air outlet, and the lower part fan cover is provided with a low-temperature flue gas outlet and a normal-temperature air inlet which respectively correspond to the high-temperature flue gas inlet and the high-temperature air outlet; outer sealing is respectively arranged between the outer circumferences of the upper part fan cover and the lower part fan cover and the outer circumference of the cylindrical heat accumulating body, and the inner parts are provided withinner sealing. The continuous-rotation heat accumulating type air preheater can realize continuous and constant-temperature air supply and effectively simplifies a mechanism.

Description

technical field [0001] The invention relates to a thermal storage device, in particular to a continuous rotary thermal storage air preheater. Background technique [0002] The "High Temperature Air Combustion Technology (HTAC)" characterized by high efficiency, energy saving and environmental protection is widely used in the field of industrial furnaces and drives the sublimation of related professional technologies. It represents the technical status of the current high-temperature regenerative air preheater. [0003] In the prior art, the working principle of switching regenerative burners is that two regenerative burners are intermittently switched by a reversing valve to control the flow of high-temperature flue gas and normal temperature air to achieve alternate heat storage and release; The heat storage device achieves heat storage and release through the 180° fixed-axis rotation of the two heat storage bodies and intermittent switching, omitting the reversing valve. ...
