Product Introduction

Present development situation of power plant sludge drying system
   Heat disposal process of power plant sludge is deep oxidation and fusion process. Through thermal disposal, partial toxic ingredients in electroplating sludge can be reduced. At present, most widely applied method is incineration which can reduce the volume and pollution of electroplating sludge. Recently, some scholars have done wide research on recycling of incineration residues. But, owing to high energy consumption, it has certain request on incineration equipment. Generally, small sized electroplate factories cannot afford this high investment cost. Therefore, it is difficult to popularize incineration method.
Taida efficient and energy-saving power plant sludge drying disposal solution
Having been specialized in sludge drying for many years, aimed at desulfurized gypsum and chemical sludge, Zhengzhou Taida Group developed a set of complete power plant sludge recycling system.
Characteristics of Taida desulfurized gypsum calcining process:

1. Customers can choose flexible heat sources, such as coal, electricity, microwave, natural gas, LPG and diesel.
2. After drying, final products can be used as fuel for boiler. dried sludge can also be used to make bricks, landfill and compost to realize
3. Environmental friendly and energy-saving; 
 

Product Superiority

1. This system can reduce materials with 90% moisture to appointed standard one time.
2. This system holds great generalization, it can even be applied to deal with liquid materials.
3. Materials routine in dryer can be controlled. Final products can be dry powder or granular materials.
4. Various heat source devices can be chosen for you. It can adopt coal, electricity, oil and natural gas as heat source. It can also apply residual heat of exhaust gas as primary and secondary indirect hot air.
5. Matched with complete system, it can meet your demands from raw material crushing, drying, pelletizing and exhaust gas disposal.
6. Matched with mature residual heat utilization technology, it can recycle residual heat.
7. With compact structure, less area occupation, low noise, less vibration and PLC control, this whole system is reliable and safe. Matched with efficient combustion furnace and exhaust gas purification device, it can realize efficiency, low energy consumption and no pollution. 
 

Technical Process

Raw material disposal system: Pretreat sludge from electroplating factories. In order to save energy consumption, we suggest customers to dehydrate sludge with 90% moisture first. If there are some large particles contained in sludge, remove large foreign matters through sorting device or impurity removal system.
Fifth generation European style drying system: taking advantage of TDOCS air swept rotary wing dryer, the moisture of sludge can be reduced to below 15% one time.
Exhaust gas purification system: make use of cyclone dust collector, bag filter, water spray dust collector, scrubber and photolysis system to eliminate harmful matters and odor.
Final products disposal system: we can provide customers with pelletizing machine. Accordingly, customers can pelletize mixture of sludge and biomass. These pellets can be used as fuel for boiler. We also provide hazardous matters packing system to pack and seal dried sludge with toxic matters and heavy metal. 
Other auxiliary equipment: we can match these devices according to customers’ requests.
