One of the promising approaches to reducing the energy consumption in the thermal distillation of liquid toxic waste is the use of immersion combustion units with the efficiency of more than 100 % relative to the lower calorific value. The development of the method of LTW thermal distillation (evaporation) in volume by means of immersion combustion units will allow wide application of the technology in the industry.
The energy-efficient technological system based on deep thermal evaporation in the ICU is developed. It is shown that the developed EETS has improved characteristics in comparison with the existing thermal treatment systems. The proposed solutions allow simplifying the vat residue processing after the LTW treatment process.
The final product of thermal distillation of toxic waste is a dry residue that does not require repeated or additional processing.
As an efficiency indicator of the LTW distillation complex, it is proposed to use the density of evaporated effluents. The paper proposes to use the vibration method of density control with simultaneous measurement of density and viscosity of controlled LTW. The structure of the automatic density control scheme allows compensating for a decrease in the resonator quality factor due to the damping of its vibrations by a viscous mediumReferences
