Abstract

An immersed integral burning evaporator for concentrating the percolated liquid of garbage filling field by burning the gas released from garbage filling field is composed of an evaporating chamber with air exhaust pipe, percolated liquid inlet tube and concentrated liquid outlet tube, and a combustion chamber with refractory linear on its internal surface. The lower part of said combustion chamber is immersed in the liquid in the evaporating chamber. It has high heat transfer efficiency and less possessed space.

Description

technical field [0001] The invention belongs to the technical field of environmental protection devices, in particular to an integrated submerged combustion evaporator for concentrating leachate. Background technique [0002] The treatment of high-concentration organic wastewater has always been a difficult problem for environmental protection workers, especially the leachate from landfills. Landfill disposal is an important part of solid waste management. For a complete solid waste management system, landfill is an indispensable key element. At present, the pollution control of the landfill is still a weak link, and the waste that is absorbed in it derives highly polluting leachate and landfill gas pollutants, especially the high concentration and large output of landfill leachate pollutants. The water quality of leachate varies widely. Not only does it change regularly with the change of seasons every year, the alternation of dry season and rainy season, but it also shows...
