Woodworking Continuous Carbonization Furnace Machinery Sludge Treatment
Sludge drying and carbonization is a newly developed sludge recycling technology by Benenv. It is the result of the painstaking efforts of Japanese experts and Chinese professors in incineration, drying, carbonization field. This technology integrates the advantages of sludge drying and carbonization, and is both stable and dioxin free during the treatment process. During the process, drying is through direct heating while carbonization is through medium carbonization, which produces high quality products.
The carbonization furnace is a horizontal rotating body, which uses indirect heating method. The hot blast furnace at its side generates high temperature and heats the rotatable furnace body. The materials in the furnace body decompose under low oxygen condition, producing a large amount of retort gas, which is led into the combustion chamber by the induced draft fan for secondary combustion. The materials are transported from the end of the furnace body, and the output end is provided with belt There is a product condensation and collection system to collect the product after cooling; the high-temperature flue gas from combustion is pumped to the super dryer for drying sludge. In terms of tail gas treatment, when the temperature in the combustion furnace reaches above 800 ℃, the dry distillation gas can be completely burned to achieve harmless treatment. After the exhaust gas is cooled by a water-cooled heat exchanger, it is dedusted by a cyclone and discharged into the atmosphere.
No bound issue
The sludge is very sticky, and has a special adhesive-phase reaction during the drying process (water content around 40%-60%). During this short period, sludge is easily caking, with hard surface, yet still mud state inside. There is a special disintegrating and mixing device inside super dryer, which rotates with high speed during drying process, and breaks the adhesive phase sludge into small particles, thus increase the drying efficiency.
No harmful gas emissions
With advanced exhaust gas treatment system, dioxins produced during carbonization can be completely decomposed, via cyclone, caustic tower, bag filter, activated carbon adsorption process as complete treatment system. Exhaust gas is highly purified, definitely better than the national emission standards.
Low running costs, energy recyclable
After medium temperature carbonization, dried sludge generates large quantities of dry distillation gas under anaerobic condition. The gas is introduced into the combustion chamber of carbonizer as heat source. The high-temperature fume is pumped into dryer as the heat source. Therefore, running cost is low while thermal energy can be utilized and recyclable.
Total sludge volume reduced by more than 90%
After dried by super drier initially, and then carbonized by carbonizer with a further volume reduction; finally, the volume of the sludge can be reduced by 90%.
Simple operation, short processing time, small footprint
The entire process is fully automatic, and in accordance with the explosion-proof safety system which is designed to reduce human activities on the environment damage. Equipment is with small size, small footprint, short processing time, high reliability, suitable for construction operations in harsh environments. The overall level of equipment and process are leading the industry.
Harmless carbonized product with a wide range of uses
After the drying and medium temperature carbonization, sludge ultimately becomes stable particles with size of 1-5mm. Meanwhile, heavy metals have been solidified and the problem of heavy metals in sludge is solved fundamentally.
we use one equipment to supply hot air ( it can be hot blast stove, the fuel can be coal, branch, biomass pellet, coal gas or other combustible gas; it can also be biomass gasifier, burner and coal spray machine etc.), on one hand, we dry raw materials by using hot exhaust gas and hot air from carbonizing chamber; on the other hand, we use hot air carbonize raw material directly. For undeveloped area, we can use simple single-layer carbonizing machine to process materials with the humidity less than 10% so we can save some investment.
Packing and Delivery
1. The normal package is wooden box(Size: L*W*H). If export to European countries,the wooden box will be fumigated.If container is too tighter,we will use pe film for packing or pack it according to customers special request.
2. We also support 20',40' container delivery, use soft packaging to protect machine well. If export to european countries,the wooden box will be fumigated.If container is too tigher,we will use pe film for packing or pack it according to customers special request.
