Definitions
- Fine-grained component and/or dry dust wastes and/or liquid wastes with low- temperature oven gas are burnt, producing combustion gases and molten slag, whereas coarse grained component is separated.
- the solution according to P-263647 enables only to separate coarse grained assortment in a form of metallic alloy pieces. Non-utilised metallic compounds, however, remain is slag. This method does not allow the recovery of pure metals from toxic metallic compounds subject to utilisation.
- Patent application P-293027/PCT/NL 91/00058 puts forward a method of combined processing of wastes where a waste of relatively high energetic value is subject to the process of pyrolysis in order to obtain gas and/or oil with coal residue.
- pyrolysis residuum is mixed with waste of a relatively low energetic value so as to form a mixture with water
- the mixture that has been obtained is shaped into pieces until it gets the form of ceramic products.
- the method proposes to add sawdust to it. This method does not make it possible to recover metals whose compounds are contained in utilised wastes.
- Oxygen is obtained from gas products of the process of the charge combustion owing to a cathode located in the area of free space inside the charge in the combustion chamber, and anodes inside each of the filter chambers with closed cycle of gases, and feeding the electrodes, from constant voltage source of safe value, during this process, and maintaining current density on a constant level, most desirably ranging from 2 to 10 A/m 2 .
- combustion is enriched with hydrogen, educed on the cathode, bonding a part of oxygen in the chamber and catalysing a reduction reaction of metallic oxides into metals.
- the installation for thermal utilisation of wastes that contain metallic compounds is characterised by a hermetic combustion chamber in oxidising-reducing conditions with cooling coil installed around the chamber, on its full height, and within the lid.
- the bottom is provided with a grid under which the air inflow is situated.
- the installation is equipped with the outlet of gases and steams tightly connected with the lower part of the first filter chamber where the cooling coil of gases and steams is embedded.
- the dry filter is over the cooling coil.
- the first filter chamber is closed on its top with a lid having a cooling coil installed. In the lid there is also the outlet of refined gases connected, through a scrubber, with a fan that is, from its other side, joined with the inlet of the second filter chamber.
- the ash being the remains of the process, after separation of pure metals in a form of powder, can be used as a high-quality binding agent, ecologically clean, useful for producing building elements of high mechanical and insulating parameters.
- the instances of the use of the installation presented on a draught - a scheme of the device - provide us with a more detailed description of the installation in the process of utilisation.
- the installation for thermal utilisation of wastes containing metallic compounds is equipped with the combustion chamber 111, surrounded on its full height with a cooling coil /14/ that is also installed in the lid 161.
- a cooling coil /14/ that is also installed in the lid 161.
- the combustion chamber 111 is tightly closed with the lid 161 in which a steel cathode 191 is embedded.
- the cathode 191 is inside it, placed in the free space 151 of the charge III.
- the chamber 111 is connected, through a cable /15/, with the lower part of the first filter chamber 712/ where the cooling coil /16/ is embedded.
- the second filter chamber /13/ on its top, is tightly closed with a lid /24/ that has the outlet to the other fan IS/ connected, through a cable /25/, both to the pressure regulation valve /26/ and to the air inlet of the combustion chamber 111, placed under the grid.
- a lid /24/ that has the outlet to the other fan IS/ connected, through a cable /25/, both to the pressure regulation valve /26/ and to the air inlet of the combustion chamber 111, placed under the grid.
- the lids /18,24/ of each of the filter chambers 111,13/ there are graphite anodes /10,11/ fed from the source of constant voltage 727/.
- the outlet of the cooling coil /14/ is connected, through the cooling coil /28/, with the heat receiver /29/ from which water, through a pump /30/ and the cooling coil /19/ goes to the inlet of the cooling coil /16/ placed in the lower part of this chamber /12/.
