A kind of perfluorohexanone rapid fire extinguishing device and fire extinguishing system

Abstract

The invention discloses a perfluorohexanone rapid fire extinguishing device, which comprises a perfluorohexanone injection assembly, a CO 2 Generating device, water mist generating device, mixing chamber and nozzle, the perfluorohexanone injection assembly is connected to the nozzle through pipelines, CO 2 Both the generating device and the water mist generating device are connected to the mixing chamber, and after being connected to the mixing chamber, they are connected to the nozzle through a pipeline. A mixed flow channel is formed, and a number of water mist nozzles are arranged on the outer casing; when the present invention is used, it is not necessary to store high-pressure gas sources in advance, and the internal pipes and valve connections of the fire extinguishing device will not be subjected to high pressure at ordinary times, which can effectively avoid leakage. , has the advantage of good fire extinguishing effect. In addition, the invention also discloses a fire extinguishing system.

Description

technical field [0001] The invention relates to the technical field of fire fighting and fire extinguishing, in particular to a perfluorohexanone rapid fire extinguishing device; in addition, the invention also relates to a perfluorohexanone rapid fire extinguishing system. Background technique [0002] Perfluorohexanone fire extinguishing agent is a highly efficient, non-toxic, clean and environmentally friendly fire extinguishing agent. The boiling point of the fire extinguishing agent under standard atmospheric pressure is about 48°C, the freezing point is -108°C, the dielectric strength is ≥110kv, and it is liquid at normal temperature and pressure. , can be partially applied or fully flooded to extinguish the fire, the fire extinguishing concentration is only 4-6%, can extinguish class A, B, C, E, F fires, can be safely applied to places with people, and there is no residue after fire extinguishing, perfluorohexanone fire extinguishing agent The ozone depletion potentia...

Problems solved by technology

The pipeline is under high pressure for a long time, and it is easy to leak at the pipeline connection and valve installation position

[0004] The application number is: CN201910321079.0, and the publication number is: CN110013638A. The invention patent discloses a fire protection system based on perfluorohexanone fire-fighting agent, which involves the field of fire protection manufacturing technology, including: perfluorohexanone storage tank, the outlet through the first The pipeline is connected to the first inlet of the mixer through the first regulating valve, one end of the second pipeline is connected to the first pipeline through a tee, and the other end of the second pipeline is connected to the inlet of the first outer ring of the nozzle through the second regulating valve ; The dry powder fire extinguishing agent storage tank, the outlet is connected to the second inlet of the mixer through the third regulating valve through the third pipeline; the water mist storage tank, the outlet is connected to the second outer ring of the nozzle through the fourth regulating valve through the fourth pipeline The inlet is connected; the mixer, the outlet is connected with the middle inlet of the nozzle through the fifth pipe; and the nozzle is used for spraying powdered fire extinguishing agent from the middle and / or spraying perfluorohexanone fine water mist fire extinguishing agent from the outer ring; but the fire When the system is in use, it is necessary to use a high-pressure air source. Under the action of the air pressure of the pressure air source, the perfluorohexanone in the perfluorohexanone storage tank and the fine water mist in the water mist storage tank respectively flow at a preset flow rate. It is connected to the second container surrounded by the casing in the nozzle and the trumpet-shaped partition; when the high-pressure gas source is stored, it is easy to leak at the connection. In normal use, it is easy to cause fire extinguishing failure
