The high-expansion foam generator is a high-expansion foam fire extinguishing device with its own proportional mixer, which is directly connected to the suction pipe of the foam liquid storage tank to form a high-expansion foam fire extinguishing device. As long as the pressure water is supplied, the fire can be extinguished. It is suitable for small Fully submerged fire extinguishing of the space, the device has high foaming ratio and easy to use. It can be fixed or mobile according to needs. It is suitable for coal mines, gas stations, basements, chemical plants and other places.
The water supply equipment of the high-expansion foam generator provides 0.3-1.0mpa of pressure water. One part of the water directly enters the water turbine through the main pipe to drive the water wheel to rotate, and drives the wind wheel to rotate through the water turbine shaft, and the other part of the water flows through the proportional mixer and flows at the nozzle. Increase sharply to form a vacuum in the vacuum chamber. The high-expansion foam liquid in the storage tank is sucked into the vacuum chamber of the proportional mixer by the suction pipe, mixed with the water ejected from the nozzle, and enters the pipeline together, and then with the water flowing out of the turbine. After mixing, the foam mixture is sprayed to the foaming net in a mist form through the four nozzles through the pipe network, and a film is formed on the inner surface of the net. The wind blown by the wind wheel onto the net blows into a large number of bubbles to form High expansion foam, flooding or covering the surface of burning objects.
After the foam extinguishing agent is mixed with water, through the foam generating device, a large amount of foam is produced to quickly cover the burning material or fill the protected space, and suffocation and cooling are used to extinguish the fire. This product must not be mixed with other chemicals and other types of foam fire extinguishing agents during transportation and storage.
Foam fire extinguishing agents are widely used in underground tunnels, airports, underground garages, oil depots, ships, coal mines and other limited space fire prevention and rescue. It is used to cover large areas of non-water-soluble flammable and flammable liquid. It is suitable for fighting fires of water-soluble flammable liquids such as alcohol, ether, aldehyde, ketone, etc.
