The air film project has large span, can realize large span of hundreds of meters, does not need any supporting structure, and has low manufacturing cost and shorter construction period. The membrane structure adopts high polymer materials, the self performance and the corrosion resistance are better, the membrane material can be a flame-retardant B-grade material, the fire resistance is good, and open fire can not be caused.
Compared with the traditional coal shed, the traditional coal storage warehouse has overhigh cost, the rented warehouse is generally charged according to space, the stability of the rented warehouse is poor, the rented warehouse is not continued or specific time is specified to carry out the warehouse sometimes due to the influence of objective factors, and enterprises need to carefully and reasonably select. The emergence of the gas film coal shed not only makes a contribution to environmental protection, but also provides convenience for a plurality of coal enterprises.
The internal space of the inflatable membrane coal shed is large, and according to foreign materials, the internal space environment of the large-volume air membrane coal storage yard is similar to the outdoor environment. Even if combustible gas is generated locally, the concentration of the combustible gas is difficult to reach combustible and explosive conditions, and the safety of coal production is further enhanced.
At present, dust pollution of large-span coal sheds of many engineering enterprises is serious, and the large-span coal sheds are listed in a forced control list by environmental protection departments in various regions, and although the large-span coal sheds are respectively provided with measures for building wind shielding and dust suppression walls, the wind shielding and dust suppression walls are not provided with top covers, the dust flying out of the upper portion of a coal yard can not be blocked, and the problem of dust flying can not be fundamentally solved. The large-span air film coal shed has excellent sealing performance, indoor coal dust is not easy to diffuse outdoors, the diffusion of the coal dust is greatly blocked, and the large-span air film coal shed is the terminator of an open-air coal yard and is the inevitable trend of environmental protection.
The air film coal shed shown in fig. 1 has a safer environment in an air film and less dust than a traditional closed coal shed, but becomes a closed space after a coal yard is fully closed, the ventilation in a bin is poor, and once dust generated in operation forms dust cloud, the dust cloud is ignited by naked fire or static electricity, and dust explosion is easily caused.
