Description

Carbon dioxide colloidal foam fire extinguishing device

technical field

The invention belongs to the technical field of fire protection, and in particular relates to a carbon dioxide colloidal foam fire extinguishing device.

Background technique

In recent years, with the large-scale use of organic foam insulation materials in the construction field of our country, civil buildings and industrial plants have repeatedly caught fire, and the difficulty of fighting fires with clean water has become difficult. It often requires a large amount of water resources to be consumed. Also burned out, the effect of firefighting can only be reflected in preventing the fire from continuing to spread outside the fire isolation zone. For fires caused by leakage of oil and other flammable storage tanks, water can only cool down at most; covering with sand, first, it is difficult to obtain a large amount of sand in a short period of time, and second, it is actually difficult to operate against large fires. Theoretically speaking, it is reasonable and necessary to use colloidal foam for fire extinguishing. However, the existing colloidal foam fire extinguishing patents include: (1) Sprinkling fire extinguishing equipment prepared by gel (CN201320391560.5), (2) A ready-to-use water-based fire extinguishing agent additive and its use method (CN201610017551.8), (CN201610017551.8), 3) Preparation method of multiphase gel foam for preventing spontaneous combustion of coal (CN200810025415.9), (4) Coal and rock fire prevention material (CN201210243676.4), (5) A fire extinguishing material and its preparation method and application (CN200910061231. 2), (6) A new type of aqueous film-forming anti-burning foam fire extinguishing agent and its preparation method (CN201510741298.6), (7) An intelligent gel material for preventing spontaneous combustion of coal (CN201410113510.X), (8) 8 such as ammonia-free gel (CN201310581681.0). Among them, (3), (5), (6), (7), and (8) the raw materials themselves include water-insoluble solid powder, and (1), (2), and (4) raw materials do not include water-insoluble solid powder materials, but their common feature is that "colloidal foam" needs to be made before spraying, and then sprayed. There are two problems: one is that the equipment may be blocked, even if it is not blocked, at least the equipment must be cleaned thoroughly after each use; the other is that the gas in the foam needs to occupy a large amount of injection flow of the injection equipment, reducing the fire extinguishing efficiency of the injection equipment , the third is that the solids therein will increase the resistance of delivery and injection, wasting energy.
