Sludge dryer drying sludge _ _ Changzhou Jinling Factory

The main features of the fluidized bed sludge drying device ⑴ flexible operation, continuous operation. According to the requirements of the final disposal of sludge by adjusting the fuel / coal, the bed velocity, quantity of sludge to obtain a different ratio of dry sludge solids. ⑵ within the fluidized bed due to the intense movement of particles in the state, mass transfer and heat transfer rate between the particles and the gas quickly, the heat transfer efficiency and a high evaporation rate can be more than 80% moisture content once dried to the humidity of materials moisture content of 5% or less, and low energy consumption. Water and sludge in the fluidized bed can instantly volatile, short drying time, the furnace temperature distribution agreement, the product of the degree of drying and particle size uniformity. ⑶ fluidized bed dryer design is compact, great handling capacity per unit area, low space occupancy, no mechanical transmission components, less failure, low construction costs and investment costs. ⑷ product dried sludge has a very good physical form (such as appearance, size, color flavor, moisture, etc.), the chemical form (water, organic matter, total sputum and trace element content) stable, will not produce secondary pollution, disposal or resource use safer. ⑸ according to different requirements, supporting different drying processes. 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.
