Technology of thermochemical waste processing

Stage 1
Mechanized feed of raw materials
The wet raw material is fed into a hopper, from where its automated mechanized supply to the drying chamber is carried out.
Stage 2
Drying stage
The wet raw materials are dosed into a drying chamber, where they are convectively dried by flue gases leaving the reactor. The steam formed during drying in a mixture with spent flue gases is fed into the cleaning system.
Stage 3
The dry raw materials are dosed by a feeder into the reactor. In the pyrolysis reactor, mechanoactivated thermal decomposition of dry raw materials takes place in the absence of an oxidizer. As a result of pyrolysis at a temperature of about 500°C, a vapor-gas mixture and a bio char are formed. The vapor-gas mixture is discharged into the energy module.
Stage 4
Combustion of the vapor-gas mixture
The vapor-gas mixture burns in the energy module to form high-temperature flue gases. Flue gases are fed into the jacket of the pyrolysis reactor to ensure the temperature level of the pyrolysis process, and then into the drying chamber.
Stage 5
Unloading of bio-char
The biochar formed during the thermal decomposition of raw materials in the pyrolysis reactor is discharged by a screw conveyor, stabilized and sent to the end user.
Stage 6
Cleaning of gas emissions
The spent drying agent, depending on the type of processed raw materials, can be released into the atmosphere after the dryer or fed into a multi-stage cleaning system. At the purification stage, gas cooling and vapor condensation are carried out first, wet chemisorption purification is carried out at the second stage, and final purification is carried out at the third stage.
