Description

Technical Field

[0001] This utility model relates to a fire extinguishing device, and more particularly to a ternary two-phase fire extinguishing device. Background Technology

[0002] In existing fire extinguishing technologies, traditional fire extinguishing devices typically use a single extinguishing medium, such as water, foam, or dry powder. While these devices can meet fire extinguishing needs to a certain extent, they have the following shortcomings when facing complex fire scenarios: First, their extinguishing efficiency is relatively low, as a single medium is insufficient to quickly extinguish different types of fires; second, their extinguishing effect is not ideal, and for some special material fires (such as oil fires and electrical fires), a single extinguishing medium may not be effective in controlling the fire; third, their extinguishing devices lack flexibility, failing to adjust the ratio of extinguishing media and the spraying method according to the specific conditions of the fire scene. Therefore, developing a fire extinguishing device that can simultaneously utilize multiple extinguishing media and improve extinguishing efficiency and effectiveness is of great significance.

[0028] Preferably, the power unit 6 is one of a gasoline engine, a diesel engine, or an electric motor.

[0029] The working principle of this utility model is as follows:

[0030] In use, this invention allows for the storage of different extinguishing agents in the two compartments of the two-part storage tank 1, or for storing extinguishing agent in one compartment and water in the other, depending on actual needs. The extinguishing agent or water is injected into the two-part storage tank 1 by opening the storage tank cover 2. The ternary element in this invention refers to the gas, water, and extinguishing agent used in fire extinguishing, or a combination of gas and two extinguishing agents. The two phases consist of gas and liquid, forming a ternary two-phase fire extinguishing device. The power unit 6 provides power to drive the axial flow fan 7. The outlet of the axial flow fan 7 outputs a large amount of gas into the fire extinguishing spray pipe 8. Simultaneously, a small amount of gas is injected into the two-part storage tank 1 through the storage tank inlet pipe 3. This allows the liquid in the two-part storage tank 1 to be discharged into the fire extinguishing spray pipe 8 through the storage tank drain pipe 4. When gas enters the fire extinguishing spray pipe 8, the two storage tank drain valves 5 are adjusted. The different extinguishing agents or water in the two compartments of the two-part liquid storage tank 1 are mixed with the air in the extinguishing spray pipe 8 and finally discharged through the atomization adjustment component. In the atomization adjustment component, the gas first enters the constriction section 13 of the constriction nozzle 10 for pressurization, and then enters the position of the expansion section 14 to diffuse with the conical structure of the turbulence cone 11, thereby achieving the atomization effect. The gas and liquid are scattered through the gap between the turbulence cone 11 and the expansion section 14 for fire extinguishing. The gap between the turbulence cone 11 and the constriction nozzle 10 can be adjusted by the installation distance of the turbulence cone support 12. When directional spraying is required, the gap between the turbulence cone 11 and the expansion section 14 is blocked by adjusting the atomization adjustment outer pipe 9, so that the atomization adjustment outer pipe 9 forms an air outlet. After the gas and liquid are mixed, they are discharged from the atomization adjustment outer pipe 9, thereby achieving the purpose of directional spraying. Adjusting the atomization adjustment outer pipe 9 realizes the adjustment of direction and atomization range.
