Problems solved by technology

However, the existing three-phase jet fire-fighting technology ignores the impact of nitrogen on the jet clustering. The existence of high-pressure nitrogen greatly accelerates the atomization speed of the jet water beam, which seriously reduces the range of fire monitors; in addition, the loss of a large amount of nitrogen will inevitably lead to increased firefighting costs

Abstract

The invention discloses a three-phase jet-flow fire-fighting monitor system for gas-powder separation. The three-phase jet-flow fire-fighting monitor system comprises a three-phase fire-fighting monitor head for gas-powder separation, a filter, a nitrogen pressurizing device and a dry powder tank; the dry powder tank is connected to a powder inlet pipe of the three-phase fire-fighting monitor head for gas-powder separation through a pipeline, a nitrogen outlet pipe of the three-phase fire-fighting monitor head for gas-powder separation is connected with one end of the nitrogen pressurizing device through the filter, and the other end of the nitrogen pressurizing device is connected with the dry powder tank. According to the three-phase jet-flow fire-fighting monitor system for gas-powder separation, the structure is simple, and use is convenient; a hydrocyclone separation device of a dry powder pipeline arranged in a fire-fighting monitor can separate out nitrogen for transporting ultra-fine dry powder, therefore, the ultra-fine dry powder and a water-based extinguishing agent are fully mixed, the atomization degree of jet flow is reduced, and the firing range of the fire-fighting monitor is widened; in addition, separated nitrogen is pressurized by the pressurizing device and then enters the dry powder tank for cyclic utilization, and therefore the extinguishing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a three-phase jet flow fire monitor system with gas-powder separation. Background technique [0002] With the rapid development of society, the total amount of high-rise and large space buildings in the city is increasing rapidly, and the building structure tends to be complex. After a fire occurs in these complex and tall buildings, the fire spreads rapidly and the high-temperature toxic gas spreads rapidly, which brings great challenges to the placement of fire-fighting vehicles and the delivery of fire-extinguishing agents in fire rescue. Putting out complex tall building fires has become a major problem in the field of fire protection. [0003] In order to further improve the fire extinguishing efficiency, three-phase jet fire extinguishing technology has become a research hotspot at home and abroad in recent years. Three-phase jet fire extinguishing technol...
