Heptafluoropropane fire-extinguishing device for ships and fire-extinguishing method thereof

Abstract

The invention discloses a heptafluoropropane fire-extinguishing device for ships and a fire-extinguishing method thereof. The fire-extinguishing device comprises a detection and control circuit, a temperature sensing detector, a smoke sensing detector, an optical detector, a release valve electromagnetic starter, a fire-extinguishing control device, a fire-extinguishing starting device, a liquid low one-way valve, an audible and visual alarm, an emergency brake / stop button, an emergency operation board, a nitrogen storage cylinder, a nitrogen container valve, a storage bottle rack, a heptafluoropropane storage bottle, a rack batten, a high-pressure hose, a heptafluoropropane container valve, a container valve electromagnetic starter, a pressure signal transmitter, a collecting pipe, a release valve, a conveying pipeline, a nozzle and a protective area. The fire-extinguishing agent refers to colorless, odorless and non-conductive heptafluoropropane without secondary pollution, and the device has the characteristics of cleanliness, environment friendliness and the like, is reliable in performance and high in fire-extinguishing efficiency, is low in requirement of technological level of safety maintenance personnel in protective places such as ships and offshore work platforms and can completely replace alkyl halide and other traditional fire-extinguishing devices for ships.

Description

technical field [0001] The invention relates to a fire extinguishing device, in particular to a marine heptafluoropropane fire extinguishing device and a fire extinguishing method thereof. Background technique [0002] The automatic fire extinguishing device is mainly composed of detectors (heat detectors, flame detectors, smoke detectors), fire extinguishers (carbon dioxide extinguishing devices), digital temperature control alarms and communication modules. Through the digital communication module in the device, remote monitoring and control can be carried out for real-time temperature changes, alarm status and fire extinguisher information in the fire prevention area. It can not only remotely monitor various states of the automatic fire extinguishing device, but also grasp real-time changes in the fire protection area , to minimize loss of life and property in the event of a fire. [0003] In the past, my country mainly used haloalkane fire extinguishing devices, but ...

AI Technical Summary

Problems solved by technology

At present, my country mainly uses carbon dioxide fire extinguishing devices to replace haloalkane fire extinguishing devices, but the amount of carbon dioxide fire extinguishing agent is large, and it takes up a lot of space and weight in protective places such as ships and offshore operating platforms, and the mechanism of carbon dioxide fire extinguishing is suffocation. The indoor oxygen concentration is reduced to a level that is not enough to burn, which suffocates the flames of general combustible substances, but also causes suffocation to people. Therefore, carbon dioxide fire extinguishing devices are not suitable for use in places where there are people working.
