    This process enables the recovery of mercury from waste containing plastic material, e.g. batteries. The waste is slowly heated while an inert gas is being introduced in a vacuum for fractionating extraction of the products of the decomposition of the plastic. The waste gases must pass through an afterburner chamber incorporating a specially shaped burner where the plastic vapors are fully combusted. The waste gases are conducted from the afterburner chamber through a cooling trap and then through a cold trap in which the mercury is condensed and can be drained off. The final stage of the process is carried out in a pulsating vacuum by the inert gas. The device in which the process takes place consists of a heated heat isolated treatment chamber (2), an afterburner chamber (6), a cooling trap (7), a cold trap (18) and a vacuum pump (23, 24) connected with pipelines (5, 12, 21). The system also includes a control unit (14) for regulating the operation of the vacuum pump (23, 24) and the settings of a shut-off valve (16) and a regulation valve (15) for the inert gas. The plastic vapors are combusted in the afterburner chamber (6) by being heated in a flame basket produced with the aid of a concave flame cup (36) made of heat-resistant material.

    one
    The invention relates to the processing of waste containing mercury and formation
    mass
    The aim of the invention is to increase the overhaul of the device.
    The drawing shows a schematic representation of the device.
    The vessel 1, in which the waste batch containing the plastic material to be cleared of mercury, is placed in the chamber 2 for hot waste treatment. Chamber 2 is sealed, equipped with a heating device 3 in the form of, for example, electrical resistance elements and a nozzle 4 for supplying an inert gas. The output-5 of plastic decomposition products leaves chamber 2 and enters chamber 6 for the after-burning of plastic decomposition products. Pipeline 5 continues until an additional cooled trap / in which gases, the passage through pipe 5, is cooled with water, which is supplied to the cooled trap through inlet 8. There is an outlet 9 in the housing of the cooled trap 7 through which the cooled water is heated. From the bottom of the cooled trap 7, the drainage pipe 10 comes out, on which the shut-off valve 11 is installed. Mercury, condensed in the cooled trap 7, flows out through the drainage pipe and is then cleaned.
    With pipeline 2 coming out
    From the cooled 7, the pressure sensor 13 is connected. This device transmits signals to the regulator 14, which controls the needle valve: N 15 at the gas inlet 4 to the chamber for hot waste treatment. Cut-off
    sh
    the valve 16 is also installed in the pipeline 12 and is activated by the regulator 14. The shut-off valve 16 remains closed when inert gas is introduced through the needle valve 15, and is open when the exhaust gases from the treatment chamber are removed from the device using a vacuum pump.
    Pipeline 12 moves away from the shut-off valve 16 to a cooled trap 18 located in the freezer compartment 17, Mercury that was not separated in the cooled trap 7 is condensed here, just like any remaining plastic material that was not burned to carbon dioxide and water. The steam in chamber 6, Cooled trap 18 contains a drainage pipe 19, which, in turn, is equipped with a shut-off valve 20 so that the separated mercury can be subjected to the same treatment as it is subjected to in a cooled trap 7,
    The finished waste gas line 21 leaves the cooled trap 18 and passes through a gas filter 22 for final gas cleaning, exiting the device. The waste gas line 21 is terminated in a vacuum pump 23, on which a fan is mounted to maintain the lower vacuum required in the initial stages of the process,
    In addition to opening and closing the needle valve 15 and the shut-off valve 16, the controller 14 also controls the operation. The vacuum pump 23 and the fan 24, the fan 24. reduces the pressure in the entire installation, while a limited amount of inert gas is supplied through the needle valve 15. After evaporation of the plastic material containing - in the charge in the chamber for hot
    processing, the vacuum pump 23 begins to reduce the pressure throughout the installation to 0.9 bar. The regulator 14 then cuts off the valve 16 and signals the needle valve 15 to slow down the supply of inert gas until: until the pressure is reached, in this case 0.5 bar. The regulator 14 then turns on the vacuum pump 23, after which the shut-off valve 16 opens and the pressure in the installation can again be reduced to -0.9 bar.
    The device allows you to significantly increase the device turnaround time.
