of information on the equality of selection and volume of filling the drum degasser. After that
turn drive the vertical movements of evacuator, lifting it to its original position, taking the siphon
tube from the drum.
After lifting evacuator to its original position trolley decoupled from the mixing unit and the
operator's command is derived from the working chamber MIN. Emptying the drum is fed into
the compaction unit liberated the packaging.
In the receiving tank due to partial neutralization of hazardous waste a reduction in class of its
hazard. Residual PCB controlled laboratory module identification and sorting.
Neutralization process is completed when the concentration of PCB in the run-off from the
reagent containers not exceeding 50 ppm. If necessary, by adding a reagent or solvent to achieve
the required hazard class.
Major part of this system is certainly a technological scheme for purification of drums pairs of
solvent - methylene chloride (Figure 11.3.1).
The main technological aids schemes are:
heat chamber (Block 1);
cu-solvent evaporator (unit 2);
condenser, cooled by the refrigerant from the refrigeration unit (Unit 3);
capacity for PCB (Block 4).
Technological process of discharging PCB from containers and their subsequent removal of
residual PCB up to environmentally safe levels includes the following operations [66]:
discharge of PCB from containers (Unit 1);
removal of PCB undrainable residue from the bottom of the drums - methylene chloride, which
is the cube-evaporator (unit 2) enters the drum, located in an oven (Block 1) and then into the
condenser (block 3);
output from the system PCB, washed from the drums of methylene chloride, which evaporates
from the cube-evaporator (unit 2) is condensed in cooled drums (Block 1) and accumulates in
them. High-boiling PCB remain in the cube-evaporator (unit 2) and after the distillation of
methylene chloride was fused into the vessel (Block 4);
release of drums that are still in the oven (Block 1), from methylene chloride. C in an oven is
just neslitogo distillation residue of methylene chloride from the bottom of the drums through the
condenser (block 3), cooled refrigerant from the refrigeration unit in a cubeFor this heat
chamber is transferred to the cooling mode, heater cold water on the radiator steam heating mode
and a temperature of 60-70 -unit (unit 2).
