200M2 Heat Transfer Area Civil/Municipal Sludge Hollow Paddle Dryer
The Hollow Paddle Dryer has a metal wall which separates the process mass from the heat source (steam or hot oil). High thermal efficiency is obtained because the heat from the thermal medium goes directly into the process mass. As the material comes into contact with the heated through and agitators, the process mass is heated via conduction. With an insulated dryer, very little heat is lost. To evaporate 1kg of water only requires about 1.2kg of steam for slurry materials. Exhaust gas is minimal and at a low temperature. Therefore, the volume of non-condensable gas from the dryer, which might require treatment, is minimal.
• The materials from such as the medicine food , chemical industry, etc. can be dried.
• Suitable for pulpiness, paste-like mixture or power raw material.
• Temperature sensing material requiring the low temperature to be dried.
• Raw materials that are easy to oxidize or explode and have strong irritative or toxic.
• Demand to retrieve of the organic solvent.
Sludge Hollow Paddle Dryer Feature
1. Low heat consumption:
Due to adopting indirect heating method, there will not be large amount of heat energy being taken away, besides there is additionally heat-insulation outside of heating drum body, therefore for paste materials, it only consume 1.2 kgs of steam to evaporate 1.0 kg of moisture inside the raw material.
2. Low cost:
For unit effective volume, there is a vast heat-convection area, thus it will shortens the processing duration, and also facilitates to reduce equipment’s sizes, in the end the construction area and space is greatly decreased.
3. Less pollution:
There is much less dust material being carried or emitted out to environment. There is also much less material solvent being evaporated, which is easy to be processed. For processing conditions such as there is contaminated material or there is solvent to be recovered, the close-circuit circulation mechanism can be adopted.
4. Low operation cost:
By adopting low-speed stirring mechanism and reasonable structure and less wear allowance, the maintenance cost is also very low.
5. Steady operation:
Due to the special compression-expansion stirring function of V-shaped blade, it makes it possible to get material granule contact with heat-transferring surfaces fully, thus within the axial inter-zones, the material temperature, humidity and mixing gradient is very small, which can guarantee process stability.
