                        Introduction

                        Processing Customized yes Capacity 200-2000 t/d Warranty 1 year
                        Product brand DINGLI Power 10kw Place of Origin Henan, China (Mainland)
                        Specifications DLMG1615 Weight Area

                        Principle

                        Coal drum dryer is mainly composed of hot blast stove, belt feeding machine, drum dryer, belt discharging machine, induced draft fan, cyclone dust collector, bag filter (or wet dust collector) and operation control system. Equipment used downstream drying process, its working principle is as follows: wet material after entering drying drum divided into the following workaround: one is the feeding area, the coal into the area exchanged with high temperature and hot air quickly evaporate moisture, the material in large Angle of guide plate copy, to be imported under a workspace;2  The copy plate area, the coal in this area is copying by copy board forming curtain material, the material with good contact with hot air, the moisture in coal rapid evaporation become water vapor, water vapor was siphoned off by induced draft fan, so as to achieve the aim of coal drying;The moisture of coal in this area is less than 15% (or less) under the state of loose, after heat exchange the materials achieve the required moisture state, and discharging out;Three is a discharging area, do not set copy plate roller in the region, the material in this area scroll taxiing to the discharge port, then complete the whole drying process.

                        Characteristic

                        1. Solve coal feeding uniformity and roading inside the dryer, overcome the problem such as intermittent feeding, before plugging material, transient capacity big, etc, which is the premise to improve the evaporation intensity.

                        1) With unique design of the buffer bin and feeder mechanism, overcome uneven feeding of intermittent feeding problems;

                        2) Set up large dip Angle on the roller feeding end unpowered spiral propeller, not only evenly sent the wet slurry into drum drying section, but also make large pieces of wet coal cutting and scattered;

                        2. Improve the internal structure design of the dryer, maximize the increasing the heating area between material and hot air, which is the basis of increase evaporation strength.

                        1) Constantly optimize roller structure layout and the feed plate design, the final setting is now a unique internal feed roller plate structure and different effect of mixing drum of whole section distribution. The dryer with all "material curtain "even no dead Angle, no gap, the maximum increase the heating area of the coal and hot air, and the heat exchange area, make the coal moisture to evaporate rapidly and was taken away by hot air.

                        2) With the original rotary drum dryer dry layer patent technology. According to the different particle's material inside the drum's heating speed and speed different, set up more groups of layer drying device, dropping grate, control of small particle materials drying and pulverization, too large particle materials have different internal and external heat drying uneven phenomenon, ensure dry uniformity.

                        3. Reasonable selecting hot blast stove furnace, optimizing its internal structure design and laying quality, reduce the air leakage rate, reduce the oxygen content in the hot air less than 5%, 700-1200 ℃ arbitrary random control process requirement of temperature points, provide the dryer with homogeneous stable heat source,which is  the reliable safeguard of coal dryer running with high strength.

                        4. Measurement and control system adopts PLC frequency conversion control technology, temperature, pressure, oxygen concentration, speed equipment, process parameters on-line interlocking spreading, realize automatic detection and control of the whole system have centralized, on-site switching function, guarantee system to maximize capacity, optimal quality, the most energy-saving mode, the safety explosion protection and stable operation.

                        5. Optimizing the allocation of gravity settling +cyclone dust collector + wet cyclone/bag dust collector level 3 by dust bag filter dust removal equipment, dust concentration < 30 mg/Nm3, guarantee dust emission standard.

                        6. The unique modular design, the manufacture, transportation, installation, assembling and commissioning platform, service concept in a more optimized design manufacturing, installation services return customers more convenient transportation, guarantee the customer's maximum benefit.

                        7. Solve the traditional dryer downstream caused in the process of the direction of dehumidifying system temperature reduced water vapor return material, improve the efficiency of drying, achieve the goal of deep dehydration.

                        8. The dryer using labyrinth and expandable graphite packing type double mechanical seal sealing mode, to ensure the safe operation of the dryer within tightly closed oxygen.

                        9. Half carbon coke cooling machine used with raw coal  dryer series, recycled half carbon carbocoal heat used for coal drying and dewatering, both to achieve LAN charcoal semi coke dry quenching cooling, and to get low moisture LAN charcoal carbon coal, and make full use of heat energy for the depth of the coal removal moisture, temperature preheating, reduce subsequent pressure of coal chemical industry equipment, comprehensive utilization of heat energy, energy conservation, environmental protection, the perfect process is more reasonable.

                        Note: the capacity of equipment is directly related to the reduction of water content of coal. The proportion of precipitation is large, and the production capacity of equipment decreases correspondingly. Specific consulting Dingli company.
