Shanxi Tianwei Steel Structure Closed Coal Silo Space Frame Project Case

With the continuation of the blue sky defense war, many enterprises are required by the environmental protection department to carry out the transformation of the open coal yard fully closed. There are still some enterprises that have implemented the traditional fully enclosed coal silo, but due to the poor ventilation conditions inside the silo, there are a series of safety hazards, and it is still difficult to pass the acceptance of fire, safety production and other departments. So, how can enterprises design fully enclosed coal silos to achieve less pollution?

In the implementation of fully closed coal silo before, the enterprise first to do a good job of preliminary preparations, such as the local environmental protection, fire, occupational health and safety laws and regulations for in-depth understanding of the location of the coal mine geological conditions, meteorological conditions, underground pipeline conditions, such as do a good job of surveying. In the implementation of the fully enclosed coal silo, it is crucial to solve the ventilation design. Enterprises can use the professional fully closed coal silo ventilation design evaluation software 1.0 to design and optimize the working conditions of the coal silo. At present, the most advanced ventilation technology applied to the fully closed coal silo is the wind screen ventilation belt technology, which can completely solve the problem of poor ventilation after the closure of the coal silo and realize zero dust spillage.

Dust will inevitably be generated during the operation in the coal silo, so it is necessary to increase the micro-mist dust suppression technology and dust purification technology when designing the fully enclosed coal silo, which can effectively reduce the concentration of dust and atomize the dust. Taking into account the occupational health and safety of the operators in the warehouse, enterprises in the fully enclosed coal silo also has a fire monitoring system, fire water cannons and explosion-proof spontaneous combustion early warning system to realize the early warning of the coal silo, so as to prevent the problem before it occurs.

In addition, the implementation of fully enclosed coal silo enterprises should also consider the cost of construction and daily operation and maintenance costs. For enterprises that have already built windbreaks, they can utilize the existing windbreaks to achieve full closure, which can save 10%-20% of the construction cost. In order to save daily operating costs, enterprises can build solar photovoltaic power station on the roof of the fully enclosed coal silo, used for coal silo lighting and production of electricity, while the water in the coal silo can be used for rainwater collection system, for the silo’s micro-mist dust suppression and plant landscaping to provide water.
