Description

Totally-enclosed dry coal shed of thermal power plant

Technical Field

The invention belongs to the field of totally-enclosed sealing, and particularly relates to a totally-enclosed dry coal shed of a thermal power plant.

Background

With the development of the industries such as electric power, chemical industry and coal in China and the improvement of the national requirement on environmental protection, the high-capacity dry coal shed becomes a necessary product in the industries. In general, a common dry coal shed can provide a large-scale storage warehouse for a coal yard by covering the coal yard, so that coal is prevented from being drenched in rainy and snowy days. Therefore, the dry coal shed should have a certain storage and operation space, and the structure of the dry coal shed must meet a certain requirement on clearance. The dry coal shed commonly used in the coal power plant at present comprises an arched cylindrical shell positioned above a coal yard, the coal yard is positioned in the inner space of the arched cylindrical shell, and at the moment, the dry coal shed is an unsealed dry coal shed. In addition, the opening of the cylinder shell of the unclosed dry coal shed can be provided with a windproof dust suppression net which is usually formed by lattice columns and plays a certain windproof dust suppression role. Meanwhile, the opening of the cylinder shell is also arched, the curvature of the upper area of the cylinder shell is larger, and the curvature of the lower area of the cylinder shell is smaller, so that the windproof and dust suppression net is usually arranged in the lower area of the opening of the cylinder shell for convenience of processing, and therefore, the dry coal shed provided with the windproof and dust suppression net is of a semi-closed structure. The unclosed dry coal shed and the semi-closed dry coal shed can store coal yards and prevent coal from being drenched in rainy and snowy days, but cannot completely shield the coal yards, so that environmental pollution caused by coal dust diffusion in wind blowing cannot be completely prevented, and the environment-friendly effect of the dry coal shed is poor. In view of the above-mentioned drawbacks of the dry coal shed, it is desirable to provide a dry coal shed capable of preventing the diffusion of pulverized coal.
