Description

Technical Field

[0001] The utility model relates to a fire-fighting device for offshore engineering, in particular to an intelligent fire-fighting linkage device for FPSO oil and gas modules. Background Technique

[0002] An FPSO is a large offshore oilfield production base. The environment where the FPSO is located is special, the sea surface environment is harsh, and there are a large number of oil and gas equipment distributed in the upper module itself. Once carelessness occurs, it is very easy to cause fire and explosion accidents. The current fire-fighting device monitors fire hazards in real time through fire detectors installed in each key area, and immediately issues an alarm once a fire is detected. After detecting a fire, the fire-fighting system will automatically activate corresponding fire-extinguishing devices, such as a foam system, a water spray system, etc., to quickly extinguish the fire source. However, this method has a limited coverage area and a slow response speed, and cannot accurately predict and control the fire before the fire occurs. Summary of the Invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a schematic structural diagram of a fire intelligent fire-fighting interlocking device for an FPSO oil and gas module of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0010] The present utility model will be described in detail below in conjunction with the drawings and specific embodiments.

[0011] As shown in the drawings, a fire intelligent fire-fighting interlocking device for an FPSO oil and gas module of the present utility model includes a fire warning device and a carbon dioxide fire extinguishing device. The fire warning device includes a gas analyzer 2. The gas inlet of the gas analyzer 2 is connected in sequence through a pipeline to the air outlet of an air suction fan 3, the air inlet of the air suction fan 3, and a smoke suction pipeline 6. An infrared temperature detector 4 is installed on the top of each of a plurality of oil and gas module device cabinets, and a smoke suction hole 5 is installed at the bottom of each oil and gas module device cabinet. The outlet of each smoke suction hole 5 is connected to the smoke suction pipeline 6 through a first electromagnetic control valve 7-1.

[0012] The carbon dioxide fire extinguishing device includes a carbon dioxide gas outlet pipeline 9. A carbon dioxide gas outlet hole 8 is installed at the bottom of each oil and gas module device cabinet. Each carbon dioxide gas outlet hole 8 is connected to the carbon dioxide gas outlet pipeline 9 through a second electromagnetic control valve 7-2. The inlet end of the carbon dioxide gas outlet pipeline 9 is connected to a carbon dioxide gas tank group 10 through a pipeline.

[0013] The signal output end of the gas analyzer 2 and the signal output end of the infrared temperature detector 4 are respectively connected to the signal input end of a fire control system 1 through data lines. The signal input ends of the first electromagnetic control valve 7-1, the second electromagnetic control valve 7-2, and the air suction fan 3 are respectively connected to the signal output end of the fire control system 1 through data lines.

[0014] The gas analyzer 2 can effectively analyze the components of the gas, whether there are combustible gases and smoke. The gas analyzer 2 is commercially available, such as the BN fixed gas alarm can be used. The fire control system 1 can obtain the infrared temperature data output by the infrared thermometer 4 and the gas component data output by the gas analyzer 2 and can control the operation of the air suction fan 3 and the opening and closing of the first electromagnetic control valve 7-1 and the second electromagnetic control valve 7-2. The fire control system 1 can adopt the existing VESDA Xtralis fire protection system monitoring center.

[0015] The working principle of this system is as follows:

[0016] The infrared thermometer 4 measures the temperature inside the device cabinet and uploads the data to the fire control system 1. If the infrared thermometer 4 detects that the temperature inside a certain device cabinet rises, the fire control system 1 controls the first electromagnetic control valve 7-1 at the smoke suction hole 5 at the bottom of the device cabinet to open, and the gas in the device cabinet is made to pass through the smoke suction hole 5 and the smoke suction pipe 6 to the gas analyzer 2 through the air suction fan 3. The gas analyzer 2 can analyze whether there are combustible gases or smoke in the device cabinet and upload the gas data to the fire control system 1. If the fire control system 1 determines that a fire has occurred, the fire control system 1 closes the first electromagnetic control valve 7-1 at the smoke suction hole 5, and at the same time opens the second electromagnetic control valve 7-2 at the carbon dioxide gas tank group 8 and the carbon dioxide outlet hole 10, and releases carbon dioxide gas through the carbon dioxide outlet pipe 9 and the carbon dioxide outlet hole 10 to the device cabinet to reduce the oxygen concentration and extinguish the flame.
