The recycling system of the haloalkane fire extinguishing agent obviously reduces the fire extinguishing agent discharged in the air, protects environment, guarantees reduction of waste of the fire extinguishing agent, and improves recycling efficiency of the fire extinguishing agent.
Description
Technical field
The utility model belongs to the recovery technology scope of extinguishing chemical, and particularly a kind of halon extinguishing agent recovery system, relate to the recycling of aviation with Halon1301 in fire-suppression bottle and Halon1211 extinguishing chemical specifically.
Background technology
Aviation is mainly Halon1301 (molecular formula: CBrF with the extinguishing chemical that charges in fire-suppression bottle
3BTM) and Halon1211 (molecular formula: CBrClF, chemical name:
2, chemical name: difluorochlobromo-methane), be commonly called as and breathe out dragon.This type of material has the advantages such as fire-fighting efficiency is high, the rear noresidue of fire extinguishing, good insulating, but because of it, belongs to greenhouse gases and depletion of the ozone layer material, and according to the relevant world, domestic and industry laws, such material is prohibited to discharge in atmosphere.China in 1991 promises to undertake that such material was produced in complete prohibition in 2010 after adding Montreal protocol.For above-mentioned reasons, when safeguarding the fire-suppression bottle that uses such extinguishing chemical, must carry out recycling by extinguishing chemical wherein.The main method that reclaims at present extinguishing chemical is that fire-suppression bottle directly is connected with storing tank hose with recovery, then utilizes the interior pressure of fire-suppression bottle, higher than the pressure reduction of pressure in holding vessel, extinguishing chemical is pressed into holding vessel.There is following shortcoming in this method: (1) fire-suppression bottle uses nitrogen supercharging, therefore will inevitably also enter into holding vessel when reclaiming, thereby causes whole volumes of holding vessel all to be used for storing extinguishing chemical.(2) entering due to nitrogen, cause the pressure of holding vessel constantly to raise, final more than or equal to the pressure in fire-suppression bottle to be recycled, make remaining part gaseous fire extinguishing agent in fire-suppression bottle pressured difference to enter holding vessel, remove the pressure in non-release holding vessel this moment, otherwise can't continue to reclaim.(3) boiling point of extinguishing chemical reduces with the reduction of environmental stress, its boiling point of depressing at a normal atmosphere is-58 ℃, therefore pressure reduces rear section extinguishing chemical to a certain extent and will become gaseous state, and in order to continue, reclaim, pressure in holding vessel will have to discharge in atmosphere, this certainly will cause the part extinguishing chemical also to be released in atmosphere, thereby pollutes and waste.
The utility model content
the purpose of this utility model is to reclaim with holding vessel for fire-suppression bottle is directly connected to reclaim with flexible pipe, namely utilize the interior pressure of fire-suppression bottle, higher than the pressure reduction of pressure in holding vessel, extinguishing chemical is pressed into holding vessel, final extinguishing chemical can't pressured difference enter holding vessel, this moment is except the pressure in non-release holding vessel, otherwise can't continue to reclaim, cause the deficiency of waste and the environmental pollution of extinguishing chemical, a kind of halon extinguishing agent recovery system is proposed, it is characterized in that, this extinguishing chemical recovery system is for placing accumulator in miniature cold storage or household freezer, accumulator is provided with import, outlet and explosion relief, the accumulator import is connected fire-suppression bottle to be recycled by cooling line with the import shut-off valve, and the installation site of fire-suppression bottle is higher than accumulator, and inlet ductwork is coiled into helical form, in order to make the extinguishing chemical in pipeline sufficiently cooled, the accumulator outlet is connected with the extinguishing chemical holding vessel with check valve by outlet shut-off valve, filter successively, and the position of accumulator is higher than the extinguishing chemical holding vessel, the accumulator explosion relief is equipped with a pressure relieving valve, automatically opens release pressure when pressure is higher than appointment pressure in accumulator, automatically closes during lower than appointment pressure.
Described accumulator volume is 35L.
The temperature that described freezer arranges is-40 ℃.
Described filter is used for filtering the impurity of extinguishing chemical, but periodic cleaning or replacing.
Described check valve is used for preventing that the extinguishing chemical of holding vessel from flowing backwards.
The beneficial effects of the utility model are to propose a kind ofly by reducing simultaneously temperature and rising pressure, to make extinguishing chemical liquefaction; thereby improve the extinguishing chemical recovery system of extinguishing chemical organic efficiency; more extinguishing chemical is recovered; and the remarkable extinguishing chemical that reduces to airborne release; protected environment; guarantee to reduce the waste of extinguishing chemical, improve the extinguishing chemical organic efficiency.
Description of drawings
Fig. 1 is that the extinguishing chemical recovery system forms schematic diagram.
The specific embodiment
The utility model proposes a kind of halon extinguishing agent recovery system.Be explained below in conjunction with accompanying drawing.
Figure 1 shows that the extinguishing chemical recovery system forms schematic diagram.In figure, placing volume in miniature cold storage or household freezer 10 is the accumulator 4 of 35L, and the temperature that freezer arranges is-40 ℃.Accumulator is provided with import, outlet and explosion relief; The accumulator import is connected with the import shut-off valve and is connected fire-suppression bottle 1 to be recycled by cooling line 3, and the installation site of fire-suppression bottle 1 is higher than accumulator 4, and inlet ductwork 3 is coiled into helical form, in order to make the extinguishing chemical in pipeline sufficiently cooled; The accumulator outlet is connected with check valve and is connected with extinguishing chemical holding vessel 9 by outlet shut-off valve 6, filter 7 successively.Its middle filtrator 7 is used for filtering the impurity of extinguishing chemical, but periodic cleaning or replacing.Described check valve is used for preventing that the extinguishing chemical of holding vessel from flowing backwards.The position of accumulator 4 is higher than extinguishing chemical holding vessel 9; The accumulator explosion relief is equipped with a pressure relieving valve, automatically opens release pressure when pressure is higher than appointment pressure in accumulator, automatically closes during lower than appointment pressure.
fire-suppression bottle is placed on outside the freezer of this recovery system, and by pipeline, with import, be connected, opening the import shut-off valve makes fire-suppression bottle discharge to accumulator, extinguishing chemical is sufficiently cooled in inlet ductwork in dispose procedure, after the pressure equilibrium in fire-suppression bottle and accumulator, remaining a part of gas in fire-suppression bottle, there are extinguishing chemical and most of gas in accumulator, pressure in fire-suppression bottle and accumulator is greatly about 290～740kPa left and right (this numerical value changes according to the difference of fire-suppression bottle volume) at this moment, because temperature is reduced to-40 ° of C, at this temperature, the saturated vapor pressure of extinguishing chemical only has 224kPa, therefore extinguishing chemical condenses into liquid state, thereby with nitrogen separation, if the pressure in accumulator is higher than 224kPa at this moment, pressure relieving valve is opened and is discharged unnecessary pressure, when in accumulator, pressure is equal to or slightly lower than 224kPa, pressure relieving valve is closed automatically.Open the outlet shut-off valve this moment, the liquid-state extinguishing agent in accumulator flows to the extinguishing chemical holding vessel under Action of Gravity Field.During pressure, check valve automatically shuts down in pressure in accumulator is equal to or less than the extinguishing chemical holding vessel, stops the extinguishing chemical in holding vessel to flow backwards to accumulator.
