With the growing number of petrochemical enterprises, the treatment and disposal of oil-containing sludge has become increasingly prominent. Relevant practitioners should attach importance to sludge dewatering to reduce environmental pollution. At present, drying equipment is an ideal choice for dewatering and volume reduction of oil-containing sludge. Below, the editor of ZJN introduces the working principle of dryers adopting low-temperature drying technology. Low-temperature drying technology is an innovative drying process. Its working principle is to improve drying efficiency by increasing wind speed and air volume while maintaining a relatively low hot air temperature within a set range. Low-temperature drying protects materials from high-temperature impact and keeps their physical and chemical properties stable. Lower temperature also inhibits the generation of harmful gases such as dioxins, avoids secondary pollution to materials, and reduces the difficulty of subsequent tail gas treatment.
Advantages of Low-temperature Oil-containing Sludge Drying Equipment
1. Energy saving and consumption reduction With low requirement on hot air temperature, the overall heat consumption during drying is reduced. Meanwhile, the waste heat from enterprise boilers can be reused as heat source, greatly cutting energy costs.
2. Stable performance The fully enclosed drying system operates steadily and reliably. It eliminates potential risks existing in conventional dryers such as flammability, explosion, toxic hazard and short circuit, ensuring safe and worry-free operation.
3. Clean drying effect Tail gas is first treated by bag dust collector and then sent to the multi-functional waste gas treatment system, finally reaching the standard for harmless emission.
