Solidifying, water removal, dedusting, the hot fume for then going out part to the non-eddy flow of residue by condensed flue gas are stirred in diffuser
Condensation promotes hot fume to remove water in the condensation of diffuser, is only to need to handle partial fume during processing, drop
The low total losses of thermal energy in the process improves treatment effeciency, has achieved the effect that height removes water, and low energy consumption, water removal
While also carried out certain dust removal process, reduce the processing requirement in later period, reduce whole water removal cost, have significant
Economic benefit.
