Annular channel refractory matter triangular support of dual-chamber kiln

Abstract

The invention relates to the technical field of dual-chamber kiln building, and discloses an annular channel refractory matter triangular support of a dual-chamber kiln. The annular channel refractorymatter triangular support comprises an inner ring wall and a triangular inclined strut. A mounting groove is formed on the outer surface of the inner ring wall. The inner side wall of the mounting groove is fixedly connected with a top plate. The lower surface of the top plate is fixedly connected with the triangular inclined strut. An expansion gap is arranged between the triangular inclined strut and the inner ring wall and is filled with a ceramic fiber blanket. The annular channel refractory matter triangular support has the beneficial effects that when the inner ring wall is heated or suffers from other factors to expand, the expansion joint consumes one part of tension of the inner ring wall, the triangular inclined strut can stop displacement of the inner ring wall, and therefore the collapse accident caused by displacement of the inner ring wall can be eliminated, and the service life of the dual-chamber kiln is prolonged.

Description

technical field [0001] The invention relates to the technical field of double-chamber kiln construction, in particular to a double-chamber kiln annular channel refractory triangular support. Background technique [0002] Double-chamber kiln is also called double-chamber parallel-flow regenerative lime kiln. The fuel is fed from the upper end of the calcination belt and flows in parallel with the raw material. Since the fuel is injected from the upper part of the calcination belt, the raw material can absorb most of the energy released by the fuel here. Moreover, the average temperature in the calcination zone is 950°C. Another important feature of the double-chamber kiln is heat storage, which uses heat storage to preheat a part of the combustion air. The thermal characteristics of co-current calcination and counter-current heat storage determine that the double-chamber kiln has great High thermal efficiency, its thermal energy consumption is lower in all types of lime kilns...
