Embodiment Construction

[0025] A coal-fired power generation company has two 600,000-kilowatt coal-fired generator sets, which need to burn about 3 million tons of coal each year. The coal yard is 100 meters wide and 360 meters long. The height of the coal pile in the yard is about 15 meters, the largest coal yard The storage capacity is about 200,000 tons.

[0026] Since the power plant is built near the sea, affected by the sea wind, the dust pollution of the coal yard is serious. In addition, there are many tourist resorts in the surrounding area, and the environmental requirements are relatively high. In order to thoroughly control the dust pollution caused by strong winds, the existing open coal yard will be built into a new type of air curtain type fully enclosed environmental protection coal bunker.

[0027] The air curtain type fully enclosed environmental protection coal bunker has a height of 45 meters, a width of 100 meters and a length of 360 meters. refer to figure 1 , figure 2 and ...

Abstract

The invention provides a roof structure and an air curtain type totally-enclosed environment-friendly bulk bin adopting the roof structure. The roof structure has a good enclosing effect and is low in cost. The roof structure is provided with a plurality of arc-shaped full-span main structure trusses of which two sides are symmetric; the structure trusses are connected with a ground base, and two sides and the middles of the structure trusses are connected through longitudinal purlines; a plurality of cable wires on which a net is laid are lengthways arranged among the main structure trusses; the cable wires and the net form an enclosed roof with sunken parts and convex parts. According to the roof structure, the turbulent flow drag reduction, slender body and other aerodynamics theories are utilized to control an airflow boundary layer, and on that basis, the air curtain type totally-enclosed environment-friendly bulk bin adopting the roof structure is provided to effectively solve the problem of flowing dust pollution in a bulk storage yard.

Description

technical field [0001] The invention belongs to the field of environmental protection and is mainly used for stacking bulk materials, in particular to an air curtain type fully enclosed environmental protection bulk material bin. Background technique [0002] Ports, thermal power plants, coal mines and other outcropping bulk material storage yards will generate dust in windy weather during operation and storage, which not only causes a large amount of material loss, but also pollutes the surrounding environment, which needs to be treated urgently. [0003] The traditional treatment technology is to set up a fully enclosed silo to fully seal the bulk material yard to prevent dust from spilling out, so as to achieve the purpose of controlling dust pollution. However, in actual implementation, due to the high cost of fully enclosed coal bunkers, poor ventilation and high temperature in the bunker, the coal is prone to spontaneous combustion, and at the same time, the dust in th...
