Ventilation design of coal storage


Since the coal storage yard is closed in a closed space, there are many problems such as dust explosion in the warehouse, spontaneous combustion of coal and occupational health and safety risks of workers. Therefore, in order to ensure the normal operation of the coal storage yard, it is necessary to plan and design a ventilation scheme with good ventilation effect to ensure the closed coal bunker. A good ventilation scheme can not only eliminate indoor dust and harmful gas pollution, provide a healthy and harmless air distribution condition in the work area, but also eliminate indoor waste heat and reduce the risk of fire and other safety accidents.
Is fully enclosed coal mostly adopt the lower shutter + top ventilation skylight way of natural ventilation, because of the great closed coal bunker capacity, coupled with the roof material is made of color steel plate closed, air heat capacity is 3.14 times that of iron under the sunshine of ambient air temperature 30 ℃, color steel surface will reach the temperature of 94.2 ℃, cause indoor temperature rise significantly. Although the ventilation scheme plays a role to warehouse within ventilation, but are not very good to solve the problem of closed coal storage in ventilation, because of bad ventilation dust explosive, toxic or harmful gases, occupational health and safety of workers, easy to increase the risk of a coal spontaneous combustion in high temperature will not be able to effectively solve the problem. So should be in the coal bunker, and, under the phase in the two end shall set the ventilation device, effectively prevent the indoor dust cloud formation, reduce dust concentration and improving indoor working environment, reduce the risk of dust explosion, At the same time, it is also conducive to the circulation of indoor air flow, the discharge of toxic and harmful gases and smoke, to meet the requirements of fire acceptance.

Shape of steel space frame structure

图片
  The steel space frame  structure can realize various spatial regular shapes such as arches, circles, spherical shells, and saddle shapes, as well as various irregular shapes. Moreover, if the same shape and different structures are compared, the cost of the steel space frame  structure is relatively low. The shape of the steel space frame  structure refers to the regular or irregular changes in the three-dimensional shape of the grid. Due to the special structure of the space frame structure and the high-precision factory manufacturing requirements, the more precise components required for the complex space frame  shape can be processed in the factory. Through the subtle changes in the angle of the screw holes of the bolt ball joints and the changes in the length of the rods, the space frame  structure can be fitted to the complex shape requirements of the architectural modeling.  At present, the space frame structure has almost become "all-match", ...

Types of steel space frame structure roof

图片
  Steel space frame  structure is widely used in various buildings, such as   stadiums, exhibition halls, high-speed railway station buildings, terminal buildings, large factories, etc.; steel space frame  structure is a large-span steel structure as the main structure; it has poles The parts have the advantages of reasonable force, light weight, good integrity and stability, large space rigidity, good seismic performance, beautiful appearance, and low cost. What are the main types of steel space frame  structures? The first type is composed of triangular pyramid units, and has three forms: triangular pyramid space frame , evacuated triangular pyramid space frame  and honeycomb triangular pyramid space frame . The second type is composed of a plane truss system, which has four forms: two-way orthogonal diagonally placed space frame , two-way orthogonally placed space frame , two-way diagonally diagonally placed space frame  and three-way space frame ....

Space frame dome structure

图片
The space frame  dome uses a spherica l dome  as the main structural system, and the outside of the space frame is covered with plates or glass according to different needs. The glass dome can meet the lighting needs of the building. Natural light is filtered into the environment through the glass interface, making the building visually light and transparent. The space frame  dome uses a bolted ball space structure  as the main structure, and the covering material can be divided into blocks according to the size of the modular. Compared with the hyperboloid molding material, the cost is lower.
