Embodiment Construction

[0011] The present invention proposes a method for recovering the halogenated alkane fire extinguishing agent in an aviation fire extinguishing bottle, which is described below with reference to the accompanying drawings.

[0012] First, establish a fire extinguishing agent recovery system that simultaneously reduces the temperature and raises the pressure to liquefy the fire extinguishing agent; according to actual needs, set the cold storage temperature to -40°C and select the pressure storage tank volume to 35L;

[0013] figure 1 Shown is a schematic diagram of the composition of the fire extinguishing agent recovery system. In the figure, a pressure storage tank 4 with a volume of 35L is placed in a small cold storage or freezer 10, and the temperature of the cold storage is set to -40°C. The pressure storage tank is provided with an inlet, an outlet and a pressure relief port; the inlet of the pressure storage tank is connected to the fire extinguishing bottle 1 to be recovered

Abstract

The invention discloses a recovery method of an alkyl-halide fire extinguishing agent in a fire extinguishing bottle for aviation, which belongs to the technical range of recovery of fire extinguishing agents. The recovery method comprises the following steps of: firstly, establishing a fire extinguishing agent recovery system which enables a fire extinguishing agent to be liquefied by reducing the temperature and increasing the pressure simultaneously; setting the temperature of a refrigeration house to be -40 DEG C and the volume of a pressure storage tank to be 35L according to practical needs; placing the pressure storage tank in the small refrigeration house or refrigerator, placing the fire extinguishing bottle outside the small refrigeration house or refrigerator; connecting the pressure storage tank to the fire extinguishing bottle and the fire extinguishing agent storage tank respectively; opening an inlet shutoff valve to release the fire extinguishing agent in the fire extinguishing bottle to the pressure storage tank, wherein the pressure storage tank is higher than the fire extinguishing agent storage tank, and the liquid fire extinguishing agent in the pressure storage tank flows towards the fire extinguishing agent storage tank under the action of gravity; and automatically recovering according to specific pressure. The recovery method diclosed by the invention has the advantages that the fire extinguishing agent discharged into the atmosphere is obviously reduced, so that the environment is protected, and the purposes of reducing the waste of the fire extinguishing agent and improving the recovery efficiency of the fire extinguishing agent are fulfilled.
