Coal storage silo structure

Abstract

The invention discloses a hybrid coal storage silo structure. The hybrid coal storage silo structure comprises a concrete silo body, a steel plate silo and a top cover, wherein the steel plate silo issupported on the concrete silo body; the top cover is arranged on the steel plate silo; and a funnel ring beam is arranged at a connecting part of the concrete silo body and the steel plate silo. Thepart below a funnel is the reinforced concrete silo body; the part above the funnel is the steel plate silo; the steel plate silo is provided with a wind-resistant ring beam and a vertical stand column; the vertical stand column is used for providing vertical support for the wind-resistant ring beam; the wind-resistant ring beam is used for providing lateral restraint for the vertical stand column; the structural system has simple force transmission and clear levels, and is not prone to buckling damage; and even if a few constructions fail, the overall structure still works and reserves timefor maintenance. The upper part is of the steel structure, therefore, the construction is simple, the construction period is short, the construction cost is low, and the economic advantage is obvious.

Description

technical field [0001] The invention relates to the structural design of a thermal power plant, in particular to a coal storage silo structure. Background technique [0002] In thermal power plants, the silo coal storage scheme is widely used. It has the advantages of small footprint, simple operation mode, flexible system scheduling, no impact on the environment, and is conducive to reducing coal loss; the current single silo Most of the diameters are more than 30m, and circular prestressed concrete silos are mostly used. Because the circular cross-section is evenly stretched under the coal pressure, it is easy to take advantage of the material, but the structural construction is complicated and the cycle is relatively long. It belongs to the node construction period in engineering . The part above the silo funnel mainly bears the ring tension caused by the storage pressure and temperature load. If the steel structure is adopted, it is easy to take advantage of its strong ...
