Gas Infrared Evaporator

Infrared Evaporators are used to evaporate and concentrate wastewater and other industrial liquids.

The wastewater is fed into the container. A slowly rotating drum immerses into the wastewater. The water adheres to the drum and is transported to the top of the drum where an infrared emitter is pointed at. The infrared radiation causes the water molecules of the wastewater to vaporise. The resulting water vapour is discharged together with exhaust gases of the radiation burner into the open air. The solid particles of the wastewater, which adhere to the drum, are removed by a metal scraper.

Eelised

• separation of solvents and dissolved components in a closed system and a single process step.
• combination of the process engineering operations of vaporisation, evaporation, crystallisation and coagulation in a single apparatus.
• no dirt and incrustation problems
• hot exhaust vapour, which consists of water vapour and flue gas is discharged into the atmosphere via a stack.
