Problems solved by technology
However, if the torch is perforated by fire, the multiphase mixture will flow into the torch and cause a fire. At present, there is no fire extinguishing device specifically for oilfield heating furnace torches that cause fire due to liquid leakage, and it is difficult to extinguish fires with torches.

Embodiment Construction
[0027] The structure of the oil field heating furnace fire extinguishing device of the embodiment of the present invention is as follows: Figure 1 to Figure 6 As shown, it includes a smoke generator 10 as a fire extinguisher, a control circuit, a main pipeline 14 for delivering smoke, a three-way joint 15 and two torch fire extinguishing units 60 . The oil field heating furnace 40 generally has two torches, so two torch fire extinguishing units 60 need to be equipped.
[0028] The gas fire extinguishing medium generator can also use trifluoromethane (nitrogen) generator, carbon dioxide generator, heptafluoropropane generator or perfluorohexanone generator, and the gas fire extinguishing medium generator in this embodiment is described by taking smoke generator as an example.
[0029] Each torch fire extinguishing unit 60 includes a branch pipeline 61, an electric control valve 62, a flash pressure sensor 63, a liquid leakage detection sensor 50 and an image video flame recogn...

The invention discloses a fire extinguishing device of an oil field heating furnace. The device comprises a gas fire extinguishing medium generator serving as a fire extinguisher, a control circuit, a main pipeline for conveying a gas fire extinguishing medium and a fire tube fire extinguishing unit, the fire tube fire extinguishing unit comprises a branch pipeline and an electric control valve, an inlet of the main pipeline is connected with a gas fire extinguishing medium outlet of the gas fire extinguishing medium generator, an inlet of the branch pipeline is connected with the main pipeline; the electric control valve is in series connection with the branch pipeline, an outlet of the branch pipeline is connected with a fire tube of the oil field heating furnace; and the control circuit comprises a controller, and the control end of the electric control valve is connected with the control signal output end of the controller. Once liquid leakage of the fire tube of the oil field heating furnace is found, the control circuit starts the gas fire extinguishing medium generator, the gas fire extinguishing medium is conveyed into the fire tube through the main pipeline and the branch pipeline, and fire disasters caused by liquid leakage in the fire cylinder can be rapidly extinguished.
Description
[technical field] [0001] The invention relates to an oil field heating furnace, in particular to a fire extinguishing device for an oil field heating furnace. [Background technique] [0002] Oilfield heating furnace, referred to as torch furnace, is a heating equipment widely used in oilfields to heat multi-phase mixed liquid in oil field production. Multi-phase mixed liquid includes crude oil, water and other impurities. The oilfield heating furnace includes a furnace body and a torch. The torch is the main heating device of the heating furnace, including a fire pipe, a burner and a smoke pipe. The burner is installed outside the furnace body and at one end of the fire pipe. The fuel is ignited in the burner at one end of the fire tube, sprayed into the fire tube for combustion, and the multi-phase mixture outside the fire tube convects and exchanges heat with the outer wall of the fire tube to realize oil-water separation. However, if the torch is perforated by fire, the ...
