Module of deactivation of liquid waste
Module of deactivation of liquid waste (MNO) can be used in conjunction with module
extraction and neutralization of waste drums or as a standalone technology node for the
elimination of only hazardous waste.
The principle of operation of the module is based on the implementation of the technology of
thermal cracking reaction mass formed in the receiving capacity of the module extraction and
neutralization of waste drums.
The main unit of the module is to install high-temperature oxidation, carrying out the thermal
cracking of PCB-containing wastes.
High-temperature oxidation is conducted in a specially designed furnace [64, 65]. The choice of
temperature, time of thermal treatment is carried out according to the analysis.
This technology is based on a set of systems of high-temperature oxidation (node thermal
expansion) and neutralization of waste gases.
Module neutralization of liquid waste includes the following main parts:
site transportation of liquid waste;
thermal cracking unit;
site preparation and dispensing of reagents;
Automated control system for the INR, which includes remote control with built-in
programmable electronic system;
site cleaning of flue gases.
Node transport liquid waste is a block with stop and control valves, pumps and flow meter,
which allows to carry out manufacturing operations for transportation of the reaction mass from
the module extraction waste site thermal cracking with the desired flow rate.
When a reaction mixture from the receiving vessel operator via remote control command is
given to the pump of liquid waste. Reaction mass through the pipeline enters the balancing
reservoir, from which gravity is sent to the site of thermal cracking. Required flow rate of waste
supplied to the combustion is controlled by the flowmeter.
Thermal cracking unit of waste is from a rotary furnace and flue gas cleaning system, mounted in
a single unit.
The furnace design allows speed control and tilt tubes, purging the working chamber and the air
temperature from 400 up to 1400 0C.
Liquid waste enters the receiving device, on which is fed into a heating zone tube furnace and
moves further along the pipe through the zone of combustion and pre-cooling. The resulting ash
residue poured from the pipe end in the hopper, cool and collected in a soft container (rubber
bag) for recycling.
For the implementation of high-temperature oxidation through the tube current waste flow by
forced air flow. Air is supplied through the suction port of the jet compressor, articulated with a
tube furnace in the cooling zone. Selecting the mode of the furnace (the temperature in the
reaction zone, the speed of the pipe, the angle of inclination, the volumetric flow rate of air
oxidation) is performed by introducing a pre-programmed modes of operation by remote
control.
Kiln gases trapped gas flow jet compressor, partially cooled. The concentration of potential
pollutants in the stream is reduced by dilution with compressed air. The cooled waste gas flow is
