EVAPORATION system is designed to efficiently evaporate waste waters and remove the settled solids buildup from the evaporator tank bottom. A submerged burner tube fires below the solution level, which achieves 95%+ energy efficiency. The hot gas contact with the liquid creates almost instantaneous vapor while the combustion gasses rapidly mix with the liquid for even heat distribution. The burner tube orifices are positioned below 180° F, allowing the tube to be continuously self purging.
Turbulence in the Evaporator tank prevents simultaneous evaporation and solids removal. The Evaporator must be turned off for a period of time to allow for settlement, prior to removal of solids from the Evaporator tank. A screw conveyor is mounted in the custom designed dehydrator bottom. Upon actuation, the screw conveyor transfers the solids laterally to an inclined conveyor or is pumped per application. The inclined conveyor extends upward above the evaporator solution level and deposits the sludge material.
