Definitions
- the present invention generally relates to a method of decontaminating from polychlorobiphenyl electro-mechanic apparatus.
- PCB polychlorobiphenyl
- the PCB absorbed by materials such as paper and wood which are normally present in most apparatus and the PCB adsorbed by the inner portion of the magnetic lamination pack or the electric windings cannot be totally removed, at least in a short time, because of its aggressiveness and therefore a portion thereof remains attached to these apparatus so that, with the passing of time, it can be dissolved in the new liquid used in substitution thereof, thereby forming a contaminating element for the latter.
- the solvent vapours are generated in the sealed chamber by associated heating means.
- the solvent vapours are generated in the sealed chamber by heating means and condensed at the top of the sealed chamber so as to perform a reflux washing of the apparatus.
- the solvent vapours are generated outside the sealed chamber and then injected therein to wash the apparatus.
- the solvent is suitably choosen so as to have, in addition to a dissolving power with respect to the polycnlo- robiphenyl, also a chemical inertia thereto so as not to give rise to compounds or combinations therewith.
- the solvent has preferably an inherent non toxicity to the contact and the inhalation of its vapours and is also compatible with the apparatus materials.
- the solvent has a distillation temperature well lower than that of PCB in order that the PCB can be readily recovered for its reuse and possible PCB entrainments during the washing can be avoided.
- the distillation temperature of the solvent is lower than the maximum temperature tolerable by the apparatus to be decontaminated.
- the distillation temperature of the solvent is suitably higher than the room temperature for handling and conservation facility thereof and in order to have the possibility of simply using water at room temperature for the solvent condensation and moreover the solvent can be destil- led without rests.
- dearomated heptane or trichloroethane is employed as solvent.
- the condensing temperature of the solvent vapours is set stepwise as a function of the average temperature of the apparatus to be decontaminated.
- the apparatus under treatment is put in a box B which is heated on the bottom and on the four lateral walls by means of jackets E through which a suitable heating fluid passes, which is fed through an inlet G, through a valve I and is dischargel through an outlet H.
- a condenser L is arranged through which water flows, the temperature of which is controlled by a thermostat M controlling a water discharge valve N.
- the temperature is controlled by a thermostat F controlling the valve I and the pressure is controlled by a vacuostat 0 controlling a solvent discharge valve P, everything so as to keep constantly the apparatus A submerged in the solvent vapours under vacuum and to cause the solvent vapours to be always condensed on the walls thereof and to flow down-wardly thereon thereby developing their flooding action accordin to the plot of Fig.4, where Tl designates the vapour condensation temperature and T2 designates the average temperature of the apparatus A under treatment.
- the solvent used in this case is dearomated eptane which exhibits all of the above mentioned features for performing the washing operation.
- the temperature T1 is stepwise controlled as a function of the temperature T2 taken over by the apparatus A, i.e. as the temperature T2 of the apparatus A approaches to vapour condensation temperature Tl, the latter is increased of a step A T, and this operation is repeated until the washing is ended.
- the box B is further provided with a solvent inlet S, a thermometer V for measuring the solvent vapour temperature and an inert gas source R connected to the box through a valve Z, a non-return safety valve Q calibrated so as to assure that the pressure inside the box B does not exceed the safety values and a drainage tube o for the gravity discharge of the polychlorobiphenyl.
- the inert gas source R during the solvent discharge operation is connected to the box B in order to avoid the air to enter therein, which could give rise to possible combustion of the hot solvent.
- the described embodiment shows a washing method with solvent reflux
- the same method could be carried out without the top condenser, or it could be otherwise carried out by providing outside the box B a solvent vapour source and then injecting the solvent vapours into the box B following the requirements for performing the washing operation.
- Figs.2 and 3 diagrammatically show the action of the solvent on the PCB during a liquid phase washing operation and during a vapour phase washing operation, respectively.
- the area A is static and therefore there is a poor solvent substitution which, when it is saturated, stops its penetration, whereas in Fig.3 there is a continuous solvent substitution with resulting higher penetrability into the components of the apparatus to be decontaminated.
- an automatic washing without the intervention of operators in contact with the PCB occurs.
- all the necessary equipment does not come into contact with PCB and, once the washing operation is ended, it is fully cleaned and deconturaimated, with the exception of the lower PCB collecting zone.
- any possibility of environmental contamination is avoided since the system does not provide circuits for the PCB containing solvent (pumps, pipes, connectors etc.), wchich could give rise to contamination problems.
- the washing efficiency is very good since the solvent retains always its dissolving capacity without ever reaching the saturation and moreover the solvent can completely penetrate within interstices also of capillary nature.
- Another advantage of this invention is the very low amount of solvent required for the decontamination and easy recovery thereof since it is sufficient an amount less than 1% of the amount required for carrying out the liquid phase washing, which results in a lower cost of solvent recovery, as this can be recovered by taking advantage of the heat supplied by the heaters by simply evacuating the box ouce the washing is ended and the PCß has been separated therefrom.
- the so decontaminated apparatus can than be recovered and reused by substituting for the PCß an usnal oil or a silicone oil or a liqaid usually employed to this end.
