Abstract

The invention relates to a fixed type class B foam extinguishing device and a control method thereof. Through the combination of a foam pump system, a water pump system and an air compressor system, class B foam, water and compressed air are mixed, foam formed at a spraying outlet is full in foaming, wild fire is not liable to be formed, and the foam can be used for extinguishment of oil fire andother liquid fire disasters. The water pump system, the air compressor system and the foam pump system are driven by individual power. Closed-loop control is conducted on a water pump, an air compressor and a foam pump through a PLC, the foam proportion can be adjusted in a large range, meanwhile the water flow can be adjusted in a large range, and thus the adjusting range of the extinguishing device becomes larger and can be adjusted freely between 20%-100% of the maximum flow. Through the fixed type class B foam extinguishing device and the control method thereof, the firefighting problem oflarge liquid fire disasters is solved.

Description

technical field [0001] The invention relates to a fixed type B foam fire extinguishing device and a control method for the fire extinguishing device. Background technique [0002] The existing fixed Class B compressed foam fire extinguishing system is composed of a plurality of series-parallel connection of pressure bottles storing water, foam liquid and compressed air premix. The amount of fire extinguishing agent stored in this kind of device is limited, and the output flow rate is fixed, so it is difficult to meet the fire extinguishing needs of complex and changeable fire scene environments. [0003] The existing vehicle-mounted Class B foam system does not actively add compressed air, and relies on fire monitors to mix into the atmosphere for foaming. The foaming multiple is small and the fire extinguishing effect is not good. At the same time, the foam is relatively wet, and it is easy to form a flowing fire when used in oil fires. Contents of the invention [0004...
