Low Noise Stainless Steel Sludge Dryer Machine Belt Sludge Energy Saving

Brief Introduction

Super Rotary Sludge Dryer is a newly developed sludge recycling technology by Benenv.We have over 40 years experience on sludge drier and carbonizer.It is the result of the painstaking efforts of Japanese experts and Chinese professors in incineration, drying, carbonization field. This device uses clean energy as heating & drying energy, and direct heating method, during which no dioxins and other toxic substances are produced.
Compared with direct sludge incineration, super rotary dryer requires less energy with low carbon emissions, in line with national low-carbon environmental requirements.

Technical advantages

1. Sludge can be reduced up to 70% after drying.
2. Short investment recovery period.
3. No emissions, no secondary pollution.
4. Low noise.
5. Save energy .
6. Integrated design, small footprint, save space.
7. Modular design, easy install.
8. Easy operation and maintenance.
9. PLC set the return air temperature automatically shut down.

Advantage

Unique mixing and crushing device to obtain even powder and granular products

The super sludge dryer is equipped with a unique crushing and stirring device in the drying cylinder, and the rotatable cylinder itself has the function of crushing and stirring. The crushing and stirring device can crush and disperse the sticky and massive materials, so as to increase the contact efficiency of hot air, and the cylinder can obtain the dry finished products with uniform quality (particle size of 1-5mm) in a short time.

No bond problem

The characteristics of sludge are very sticky, and there is a special sticky phase in the drying process (moisture content is 40% - 60%). In this very narrow transition section, the sludge is very easy to agglomerate, the surface is hard and hard to crush, but the inside is still slime. However, the equipment has a unique crushing and stirring device. When the sludge is dried in the cylinder, the device will rotate at a high speed, and the sludge in the sticky phase will be completely crushed into small particles, so as to improve the drying efficiency.

Large thermal capacity coefficient and high thermal efficiency

Through the composite effect of crushing and stirring device and cylinder rotation, the total heat transfer coefficient is increased to 2-3 times of that of ordinary rotary dryer (UA = 200-600w / m2k).

Controllable moisture content and wide application

Due to the change of exhaust temperature with the change of evaporation, the device adopts corresponding control measures in the design and construction to cope with the change so as to ensure the control and management of product moisture content. Therefore, the device can be applied to materials with different properties, floccules and lumps, etc.

Easy to operate and maintain

The mechanism is simple, few parts need to be tested and easy to maintain. The operator uses the touch operation panel for production operation. If there is a fault, there will be a fault prompt on the operation panel.

Energy saving and high economic added value

After the material is crushed, the contact area between the material and the hot air is increased, the hot air is fully utilized, and the exhaust hot air is recycled, which greatly reduces the energy consumption. The dried product is a particle with a particle size of 1-5mm and high calorific value. If it is processed, it can be used as fuel.

Working Principle
1. the circulation of sludge dryer break the traditional sludge dewatering and then dry system, Energy is alternately circulated
by two systems to discharge water to achieve reduce sludge .
2. Heat exchanger system generated heat to enhance the circulating air temperature, circulating air through the sludge,hot air make sludge moisture spread to the enclosed air, when the circulating air through the cold heat exchanger, the circulating air temperature decreases, the air moisture temperature drop . After the condensed dry air recirculate to the heat exchanger discharge.

Character of sludge drying

Belt sludge drying machine is a highly efficient, energy-saving, environmentally, which uses high-temperature pump to dry heat source, the dehydration of sludge at 60-100 ℃ conditions, moisture content from 80% to 30% .The whole process enclosed,
no smell overflow. External heat, cooling water and other harsh conditions , it can be installed immediately.80 degrees above the waste hot water as heat source. Belt dryer can be modular design,through increase the number of dry modules to increase ca-pacity .it can be customized according to customer requirements. The capacity of the SFC-BCDseries dryers is from 100kg / h of
steam to 600 kg / h. The equipment is modular and has low on-site conditions and suitable installation on all occasions.It can be work with other device and apply to medium and small sites.

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.
