Storage tank fire hazard water curtain spraying protecting system for large-size tank area

Abstract

The invention relates to a tank area fire-fighting device and belongs to a storage tank fire hazard water curtain spraying protecting system for a large-size tank area. According to the device, when fire hazard happens in one storage tank in the tank area, the water curtain spraying system can be automatically started, then thermal radiation can be effectively blocked, and the tank is sprayed so as to be cooled, and thus the purposes that the tank in accident is prevented from failure of temperature increasing and adjacent storage tanks are protected are achieved. The system consists of a fire hazard sensing subsystem, a fire-fighting water supply subsystem, a tank area spraying tube net subsystem, a water curtain spraying subsystem and a control subsystem, wherein the water curtain spraying subsystem takes the shape of a door and is separated from the storage tanks by a certain distance; the height of a door-shaped horizontal water supply pipeline is identical to the height of a tank body; a plurality of water curtain nozzles and mist nozzles are respectively arranged vertically downward on the pipeline and are arranged at the positions which face to the positions of the tanks and are vertical to the pipeline. The storage tank fire hazard water curtain spraying protecting system has three starting modes, namely, a manual starting mode, an automatic starting mode and an emergency starting mode.

Description

technical field [0001] The invention belongs to large-scale tank farm fire-fighting facilities, and is a large-scale tank farm storage tank that prevents the wall of the accident storage tank from heating up and fails, and prevents the accident from spreading and causing the domino effect of surrounding storage tank accidents when a fire or explosion accident occurs in a storage tank in a tank group. Fire water curtain sprinkler protection system. Background technique [0002] After a fire occurs in a storage tank in a large tank farm, it is difficult to fight the fire, and it is easy to cause an accident domino effect, causing damage to adjacent storage tanks and leading to the expansion of the accident. Therefore, it is necessary to adopt uninterrupted spray cooling for the accident storage tank and the storage tanks around the accident storage tank. At present, the spray cooling method mainly relies on the fixed spray device on the storage tank combined with the fire wate...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in order to overcome that the fixed spraying device on the existing storage tank is easily burned out by the oil tank fire in the event of a fire; the water consumption of fire water guns and water cannons is too large, resulting in waste of water resources and accidents. The problem that the tail water is difficult to deal with, the present invention provides a water curtain spray protection system for storage tank fires in large tank farms, which can effectively overcome the above-mentioned problems faced in the current fire protection process of tank farms
