1. Introduction to Sludge Dryer With the strengthening of national energy conservation and emission reduction, the improvement of national environmental awareness, and the increasing production of urban sludge, the issue of sludge disposal and development and utilization has become an important issue in the national environmental protection work. The development of sludge drying treatment technology has made it possible to use sludge in agriculture, sludge fuel, and sludge incineration. The improvement and innovation of sludge drying technology and sludge dryers have directly promoted the development of sludge disposal methods, expanded the selection of sludge disposal methods, and made them safer, more reliable, and more sustainable. Get more and more reliable guarantees. Mining Construction Machinery has always been at the forefront of sludge environmental protection treatment technology. The energy-saving and environmentally friendly sludge drying equipment developed can dry the sludge to the required moisture, which facilitates the production and manufacturing of sludge bio-organic fertilizer. It is an organic fertilizer manufacturing enterprise The preferred drying equipment.
2. Sludge dryer structure
The main components of sludge dryer equipment: screw conveyor, feeder, thermal dryer host, induced draft fan, cyclone dust collector, unloader , deodorization equipment, etc.
3. Sludge dryer process
The sludge is transported to the feeder by the screw conveyor, and enters the drying chamber of the sludge dryer through the chute. As the dryer cylinder rotates, The sludge is guided to the inclined lifting plate and is lifted to the center of the cylinder, where it is gradually dropped to form a material curtain. High-temperature airflow passes through it, preheating the sludge and evaporating part of the water. When the sludge is spilled and moved to the movable rafter wing, the material is mixed with the preheated rafter wing, which transfers heat to the material and evaporates part of the water. At the same time, the material carried by the wing plates is lifted and dropped, repeated many times, and the material and the hot air flow conduct convection and contact heat exchange. At the same time, the cleaning device buried in the material also slides down along the inside of the arc-shaped lifting plate to clean the material adhered to the inner wall of the lifting plate. When the cleaning device rotates along the vertical line with the cylinder, it is dragged on the back of the arc lifting plate to clean the material adhered to the outer wall of the lifting plate. As the cylinder continues to rotate, part of the water evaporates, and the sludge is further dried. At the same time, the cleaning device also plays a role in breaking up the sludge pellets, improving the drying speed. Finally, the sludge is dried and turned into low-moisture loose materials, which are discharged from the discharge port. Fine dust is collected and recovered by cyclone dust collector. The high-temperature exhaust gas is purified and deodorized by the deodorizing equipment and then emptied.
4. Performance characteristics of sludge dryer
The new environmentally friendly sludge dryer equipment developed by Construction and Mining Machinery can dry materials with high moisture content into finished products at one time. For sludge drying It is easy to form lumps during the drying process.
. Changed the material plate structure of the general single-channel dryer and adopted a combined self-cleaning device, which greatly expanded the application scope of the single-channel dryer. It can not only dry all kinds of sludge, but also dry Various high-bonding, high-moisture materials.
3. The complete set of sludge drying equipment adopts the latest energy-saving design. The inlet and outlet and connecting parts adopt spring-type seals and temperature control devices to ensure the drying efficiency and finished product quality to the greatest extent
