Background
Solvent extraction, also commonly referred to as liquid-liquid extraction, is an effective method for separating, enriching and extracting useful substances from a solution. It uses different distribution of solute between two immiscible liquid phases to achieve the purpose of separation and enrichment. Extraction separation is an important unit operation process in hydrometallurgy and is widely used for separating and purifying different metals in the nonferrous metallurgy industry.
The extractant used in the extraction process is an organic reagent which is capable of being bound by the metal to be extracted, causing the latter to be transferred into the organic phase. The atmospheric pressure extractant comprises P204, N235, P507, PT5050, 5709, Cyanex272 and the like. In the extraction process, the extractant is dissolved in some organic solvent in order to improve the physical properties of the extractant, to reduce the specific gravity, to reduce the viscosity and to improve the extraction capacity of the extractant (to improve the oil solubility of the extractant and the extractant composition). Such organic solvents that are not chemically bound to the extracted metal are referred to as diluents. In the industry, the diluent is kerosene, heavy solvent oil, benzene, diethylbenzene, carbon tetrachloride, chloroform and the like, and the extraction unit in the hydrometallurgy industry mainly adopts sulfonated kerosene.
Sulfonated kerosene (260# solvent oil) has a flash point of about 65 ℃, a relative density (water ═ 1) of about 0.8, and a relative vapor density (air ═ 1) of greater than 1.

When the high-pressure oil pipeline is broken, the sprayed oil is in a mist shape, and the fire spread is rapidly caused.
2) In the process engineering of an extraction workshop, if the process is improperly controlled or failed, part of sulfonated kerosene volatilizes into the air in the recycling process, and kerosene steam volatilized into the production environment and the air can form an explosive mixture and explode when exposed to open fire and high heat energy.
3) Other process equipment malfunctions or fails to operate properly, resulting in equipment failure and high temperatures, which may cause fire.
4) The industrial extraction plant is basically a high and large space, and the arrangement of a large-area automatic spraying fire extinguishing system is difficult.
Aiming at the fire safety protection problem of the industrial extraction plant, the production enterprises put forward urgent and higher safety solution requirements. Therefore, under the large space of the class C industrial extraction plant and the environment with complex fire variety, what kind of efficient and targeted fire extinguishing mode is adopted is necessary to ensure that the safety production requirement of the industrial extraction plant is met.
