Foam spray fire extinguishing device

Abstract

The invention discloses a foam spray fire extinguishing device, which comprises a power bottle set, a driving device, a water storage device, a foam stock solution storage device and a zoning valve, wherein the power bottle set is connected with the water storage device through a collecting pipe; an output pipeline of the water storage device is divided into two paths through the zoning valve, and the two paths are communicated with two independent tank bodies of the foam stock solution storage device; and a capsule filled with a foam stock solution is arranged in one tank body of the foam stock solution storage device, and the other tank body is communicated with the capsule and provided with a spray outlet. Fire fighting water and the foam stock solution are separately filled in the fire extinguishing device, so that the storage time of consumables is prolonged, and the using cost of a fire fighting person is reduced; the problem of corrosion is not considered in a water tank (the water storage device), and a common normal pressure storage tank can be adopted, so that the manufacturing cost is reduced; and after being used up, the foam solution and the water can be filled in a ratio, so that continuous fire extinguishment can be realized.

Description

technical field [0001] The invention relates to fire extinguishing equipment, in particular to a foam spray fire extinguishing device in which foam stock solution and fire fighting water are stored separately. Background technique [0002] The existing foam spray fire extinguishing device is mainly composed of a driving device, a power bottle group, a foam mixed liquid storage device and a partition valve, such as figure 1 As shown, the foam stock solution and fire-fighting water in the fire extinguishing device are premixed and stored in the foam mixture storage device. Since the validity period of the conventional foam (aqueous film-forming, fluoroprotein, etc.) premix is ​​usually much shorter than the foam stock solution, the system must be frequently Replacing the premixed foam liquid stored in the whole tank is inconvenient for system application and the waste of materials is serious. Moreover, the fire extinguishing agent is highly corrosive, and the foam mixture sto...

[0002] The existing foam spray fire extinguishing device is mainly composed of a driving device, a power bottle group, a foam mixed liquid storage device and a partition valve, such as figure 1 As shown, the foam stock solution and fire-fighting water in the fire extinguishing device are premixed and stored in the foam mixture storage device. Since the validity period of the conventional foam (aqueous film-forming, fluoroprotein, etc.) premix is ​​usually much shorter than the foam stock solution, the system must be frequently Replace the premixed foam liquid stored in the whole tank, the system application is inconvenient and the material waste is serious

Moreover, the fire extinguishing agent is highly corrosive, and the foam mixture storage device must use stainless steel storage tanks, which is costly. After the fire extinguishing agent is used up, it needs to be refilled to extinguish the fire again, and continuous fire extinguishing is not possible.
