2. Air curtain ventilation belt technology. It is difficult to solve the ventilation problem of fully enclosed coal bunker, mainly because coal dust cannot overflow during ventilation. Generally speaking, wind can come in, but coal dust can't go out. The air curtain ventilation belt is designed by making full use of aerodynamic principles, with excellent ventilation effect and zero dust overflow. It is the most advanced fully enclosed coal bunker ventilation technology at home and abroad.
3. The technology of transforming the wind wall into a fully enclosed coal bunker. Because many enterprises have implemented the wind and dust suppression wall, many enterprises will dismantle it when it is completely closed, which has caused great waste. The technology of transforming the windbreak and dust suppression wall into a fully enclosed coal bunker adopts a brand-new design concept and technology, and makes full use of the original windbreak and dust suppression wall of the enterprise. In popular terms, it is to add a "cover" to the original windbreak and dust suppression wall. Compared with the traditional fully enclosed coal bunker, the project cost is saved by more than 20-30%, and the dust completely overflows, which fully meets the requirements of environmental protection.
4, fully enclosed coal bunker ventilation transformation technology. The fully enclosed coal bunker has been built and put into operation. Due to poor ventilation, the working environment in the bunker is bad. Especially in hot summer, the temperature in the warehouse is as high as 50 degrees, and workers are in danger of pneumoconiosis and high temperature exposure. At the same time, due to the high dust concentration in the warehouse, once a dust cloud is formed, there is still the risk of dust explosion. The ventilation transformation technology of fully enclosed coal bunker can transform the fully enclosed coal bunker that has been built and operated. After the transformation, the ventilation is good, and the dust explosion and the labor health risk of operators are reduced by more than 70%.
5. Fully enclosed environmental protection small silo technology. The open-pit coal yard is large in area, with many piles and many kinds of coal, so many enterprises can't be completely sealed. The fully enclosed environmental protection small silo technology can seal a single material pile, with good sealing effect, easy to meet environmental protection requirements, and the project cost can be saved by more than 30%.
6, fully enclosed coal bunker roof solar power station. Due to the large roof area of the fully enclosed coal bunker, the solar power station can provide electricity for the operation and lighting of the fully enclosed coal bunker. Generally, a 20,000-square-meter roof can build a 2 MW solar power station with an annual power generation of 2.4 million kWh. After personal use, the rest can go online. The service life of solar power station is 25 years, and the investment can be recovered in about 5-6 years, with considerable economic benefits.
7, fully enclosed coal bunker toxic and harmful gases, explosion-proof and coal spontaneous combustion monitoring technology. Because of the high dust concentration in the fully enclosed coal bunker and the gas released by coal, there is a risk of dust explosion and workers' occupational health and safety, and coal is prone to spontaneous combustion. Once spontaneous combustion occurs, there are major fires and safety hazards. The monitoring technology of toxic and harmful gas, dust explosion and coal spontaneous combustion in fully enclosed coal bunker can realize all-weather dynamic monitoring. When the monitoring value exceeds the warning value, it will immediately alarm and start the dust suppression equipment and fire fighting equipment in the silo.
8. Micro-fog dust suppression technology in warehouse. Due to the large amount of dust generated during the operation of the fully enclosed coal bunker, the dust concentration in the coal bunker is high. Dust clouds will explode, and workers who inhale dust for a long time will cause pneumoconiosis. The micro-fog dust suppression gun adopts the latest design, rotates 320 degrees, can directly use seawater, has a range of more than 100 meters, and has good atomization effect.
9, fully enclosed coal bunker rainwater collection technology. The rainwater collection technology of fully enclosed coal bunker can collect rainwater for greening, realize recycling and create a green coal bunker.
10, warehouse dust purification technology. This technology adopts water curtain purification, which can quickly reduce the dust concentration in the workplace, with low operating cost, ensure the occupational health and safety of workers, and meet the requirements of laws and regulations of environmental protection, labor hygiene and other departments. It is especially suitable for enterprises with small coal bunker area and large dust in the bunker.
