Technical introduction

On sludge disposal and sludge reclamation, Zhengzhou Taida has accumulated rich experience. Taida can provides techniques for printing dyeing plant, electroplating plant and sewage treatment plant in order to achieve reduction, reclamation and harmlessness. With its easy operation and green feature, this technology can not only creat good social effects, but also can bring about positive environmental and economic effects. it can be applied to disposing domestic wastes, rubbers, plastics, oily sand, oily sludge. 
Heat conducting oil sludge dryer


Process characteristics:
1. double-screw sludge dryer holds less energy consumption; indirect heat; no much air carries out heat; insulating layer is set on outer body of dryer;
2. low cost; large heat transfer area; short process time; small size of equipment; reduces the building area and space;
3. can applied to many materials; use different heat media; can not only process thermal sensitive materials, but also can process materials which need hot temperature; normal media: steam, heat conduction oil, hot water, cooling water and etc. can be operated constantly and intermittently;
4. less pollution; no use for carried air; less dust; small evaporation amount; easy to dispose; can adopt closed circuit;
5. less operation cost; low speed mixture; reasonable struture; less wearing parts; less maintenance cost;
6. stable operation; materials can get full contact with material granularity; the gradient of temperature, moisture and mixture degree is not large, which gurantees the stable operation;

Working principle

Principle of equipments:
Double-screw sludge dryer which regards steam as heat source is developed by our company by combining with advantages of foreign drying equipments.
Double-screw sludge dryer is a kind of dryer which adopts indirect heating and low-speed mixing. It can be operated constantly. It is a kind of eneygy-saving drying equipment. Steam flows to screw blades through hollow shaft. The design of inner passway is very special. With clever design, the two shafts can rotate conversely. Extrusion and relaxation actions will be produced between shafts. With the constant mixture and stir of screw blades, the heating area of materials can be updated. Evaporation efficiency gets improved greatly. The area for heat transferring is enlarged in unit effective volume.
This equipment adopts steam as heat media and indirect heat conduction. All amount of heat is used for heating materials. Washing force is produced by the relavant movement between materials garanularities and wedge. This washing force can wash out the materials attached onn wedge and help keep a clean heat transferring area in the running process. The shape of screw dryer’s shell body is W. generally, there are two hollow shaft installed in the shell bady. There is also an insulation end covering the top, which can not only avoid the leak of materials and dust, but also can collect material solvent vapor. There is a damper installed on the discharge port in order to gurantee the height of material’s level. Then the heat-transfer surface can be fully covered by materials and can fully play its role. Heat-transfer media will flow to jacket and hollow mixing shaft through rotary revolving joint to gurantee best heat-transferring effect.
