Abstract

The invention discloses a low-pressure carbon dioxide fire-extinguishing system, comprising a fire extinguishing device, a heating device and a control cabinet. The fire extinguishing device comprisesa storage tank, a starting pipeline and a CO2 conveying pipeline, wherein the starting pipeline and the CO2 conveying pipeline both communicate with the storage tank; the CO2 conveying pipeline has amain conveying pipeline and at least two branch conveying pipelines; the branch conveying pipelines communicate with the main conveying pipeline; the branch conveying pipelines are provided with selector valves and nozzles; and the main conveying pipeline has a service valve, a main valve and a pressure switch. The starting pipeline comprises a main starting pipeline and at least two branch starting pipelines, wherein the main starting pipeline communicates with the branch starting pipelines and is provided with a starting pipeline service valve, a pressure reducing valve and a first electromagnetic valve; the main starting pipeline is connected with the main valve; the branch starting pipelines are provided with second electromagnetic valves and connected with the selector valves. The storage tank has a refrigeration unit. The heating device is mounted on the storage tank. The low-pressure carbon dioxide fire-extinguishing system of the invention satisfies the requirements on fire protection in areas with low-temperature harsh environments, and is convenient to maintain; and since the dual mode of heating and cooling is adopted, the application environment of the system is expanded.

Description

technical field [0001] The invention relates to a low-pressure carbon dioxide fire extinguishing system, which belongs to the technical field of fire protection. Background technique [0002] The fire extinguishing system in which the carbon dioxide fire extinguishing agent is stored at a temperature of -18°C to -20°C is called a low-pressure carbon dioxide fire extinguishing system; it mainly uses a refrigeration system to reduce the storage pressure of the fire extinguishing agent to increase the storage capacity of the container. If the ambient temperature is lower than -23°C, the system should also be equipped with a heating device. Through the linkage control of the heating and cooling device, the storage pressure of the low-pressure carbon dioxide fire extinguishing system can be stabilized in the range of 1.72MPa to 2.24MPa. The temperature is high, the carbon dioxide storage pressure is high, the container is unsafe, and the filling volume is low; the temperature is ...
