Saving sludge dryer sludge dryer Changzhou Jinling

Fluidized bed sludge drying wet sludge mechanically dewatered by conveyor into a fluidized bed dryer, was suspended at boiling temperature flue gas effect, hot smoke and sludge in the cross-counterflow, the high temperature As efficient flue gas heat exchange medium, sludge to evaporate in a boiling process. Fluidized bed dryer specially designed internal structure can be made from one continuous wet sludge was added, and the product of dry sludge is continuously withdrawn from the other end. It is recovered by evaporation of water through the condenser side back to the sewage treatment system. Part of dry sludge and wet mud in a mixer and then into a fluidized bed dryer. Sludge pyrolysis under anaerobic or anoxic conditions, heated to a certain temperature (temperature: 500-1000 ℃, low: less than 500 ℃), the solid material is decomposed into oil, non-condensable gas and charcoal three combustibles . Paddle dryer is a conductive heating of low speed agitation type dryer. Set in the dryer cylinder jacket, hollow shaft hollow blades set, in which the heat carrier through the wet material agitation in a stirring blade and blade cylinder sufficiently hot surface heat exchange, in order to achieve the purpose of drying . Structure is generally horizontal, biaxial or four axes. The company introduced foreign technology, based on the development of the second generation of hollow paddle dryer. Its performance and strength greatly improved, thus becoming one of the most professional manufacturers. The company is currently developing other applications paddle drying models. Sewage sludge is the product of the post, is extremely complex heterogeneous body made of an organic debris, bacteria, bacterial, inorganic particles, colloidal sludge and other components. The main characteristics of the sludge is high moisture content (up to 99%), organic matter content, easy to corrupt smelly and smaller particles, smaller proportion, as a gum liquid. It is between the thick matter between liquid and solid, you can use a pump transportation, but it is difficult to solid-liquid separation by settling.
