Sludge dryers purposes

Sludge Sludge dryer is mainly composed of induced draft fan, scatter device, belt type feeding machine, feeding machine, rotary drum, heat source, belt type discharging machine, discharge device and distribution cabinet composition. So the single channel sludge dryers working area including discharge area, inclined Yang material plate area, cleaning area, guide area constitute. one, guide area, wet sludge into this area and high temperature hot air contact rapidly evaporating moisture, material in the big guide Angle of copy plate copy moving, bonding was into the next working area; Second, the discharge area, roller in this area do not set copy plate, and the material in this area rolling planing to discharge gate, complete the whole drying process; Three, cleaning area, wet sludge in this area is copy plate taking up form material curtain state, and the material easily fall form bonding drum wall phenomenon, in this area due to the equipment design have cleaning device, cleaning device was reasonably clean the wall adhesion material, in the process, cleaning device for material group ball agglomeration and the crushing effect, thus increasing the heat transfer area and improve the drying rate; Four, the tilt Yang material plate area, wet sludge in this area has a low moisture loose state, and the material in this area have do not have caking phenomenon, after heat exchange after material to reach the required water state, enter the final discharge area.. Has a variety of microbial river ditch sludge has been ignored by people, and for the urban environment governance to bring a lot of problems. Our factory research and development of sludge drying equipment will be sludge drying, facilitate sludge biological organic fertilizer production, is organic fertilizer manufacturing enterprise of choice for drying equipment.

Along with the national economic strength enhancement, the national environmental protection consciousness enhancement, urban sewage treatment industry is rapidly developing, the output of sewage sludge increases, sludge disposal and utilization problem increasingly pays close attention to for people place. Sludge drying processing, make the sludge farm, as fuel use, incineration and landfill to reduce the processing methods such as possible.

Working principle

Our factory research and development of new sludge drying machine, one-time will 90% moisture content of materials to finished drying. According to the sludge drying process easy knot unity block characteristics, changed the general single channel drier material plate structure, using a combined self cleaning device, greatly expanded the single channel drier application range, not only can dry all kinds of sludge, still can dry all kinds of high viscosity material.

Sludge by feeder the chute into drying machines guide plate, with the rotation of the barrel, sludge was guide to tilt Yang material board is to ascend to the barrel of the center position, and gradually spatter formation material curtain, the high temperature air through from, make the sludge preheating and evaporation of water. When sludge spatter, moves to the activities of the cage bar type wing plate, material and preheating the cage bar type wing plate mixed together, will heat to material, make the moisture evaporation. At the same time, the wing with a powder materials, spatter, repeated many times, the material and heat flow heat convection and contact. At the same time buried in the material of the cleaning device, and lift up along the circular arc of the plate material in side down, the material plate wall adhesion material cleaning down. When cleaning device with barrel turned vertical later, and in the circular arc Yang material plate back drag, its adhesion in Yang material plate of the outer wall of the material cleaning down. Along with the barrel continuous rotation, so that some of the moisture evaporation, sludge further drying. At the same time, cleaning device for sludge group ball also play a broken effect, improve drying speed, finally after drying sludge into low moisture of loose material, the discharging mouth discharge.

Sludge dryers types

The most common sludge drying equipment is single channel rotary drier:

Applicable for urban sludge drying. Single channel rotary drier is in general rotary drying machine developed a kind of new equipment. Internal installation depolymerized institutions, activity cage bar type wing plate, cleaning device and broken strong device, can dry general rotary drier can't handle viscous material. According to the sludge has certain viscosity, particle degree small wait for a characteristic, single channel drying machine is the best choice. The single channel rotary dryer, downstream process, the use of special design of feeding device, in the sludge into the dryer moment quickly and high temperature hot flue gas for heat exchange, forming on the surface layer of encrustation, so that greatly reduce sludge adhesion barrel and accumulation plugging material phenomenon. Head quarter in dryer section, except installation Yang material plate outside, also install aggrandizement evaporation depolymerization institutions and link type cage bar wing plate, not only can conduction heat, but also can prevent sludge NianDu barrel and uplift material plate, make full use of feed end drying rate fast characteristic, realize layer upon layer "stripped" way of making its can quickly drying.

Sludge drying machine can be widely applied in activated sludge drying, sewage sludge drying, petrochemical sludge drying, papermaking sludge drying, dyeing sludge drying, tanning sludge drying, electroplating sludge drying, municipal sludge drying, biological fermentation bacteria slag, etc. Various kinds of sludge and all kinds of bad slag etc materials and humidity drying.
