Description

TECHNICAL FIELD

[0001] The application relates to an explosion-proof safety warehouse. BACKGROUND

[0002] The explosion-proof safety warehouse is a warehouse for storing dangerous goods, some of which are flammable and explosive products. Due to the property of the safety warehouse, not only the fire ventilation, tail gas treatment and the like need to be considered, but also how to reduce or even lower the harm as much as possible in the event of a fire. In order to reduce the harm as much as possible in the event of a fire, a fire extinguishing ball is usually used for fire extinguishing. However, the fire extinguishing effect of the fire extinguishing ball is poor, and the fire extinguishing ball can extinguish very small fires, but cannot extinguish larger fires. Some use direct water spraying, which has a good fire extinguishing effect, but may damage the original structure inside the safety warehouse, causing greater problems. Therefore, the fire extinguishing measures of the explosion-proof safety warehouse need to be improved to reduce or even lower the harm of the fire as much as possible. CONTENT OF THE UTILITY MODEL
