Sludge pump is a possible treatment of industrial sludge waste equipment for sludge treatment, for now on so few viable option, in this one, and the number of the most effective sludge incineration. Sludge treatment types of sludge digestion, sludge dewatering, sludge filtration, sludge drying, sludge incineration, here we work together to understand the working methods of sludge drying: sludge drying is through percolation or evaporation and other effects, the process of removing most of the moisture from the sludge, generally refers to the use of sludge drying field (bed), etc. Since the evaporation facilities or the use of steam, gas, oil, heat, dry heat of the facility. High viscosity sludge drying equipment commonly used hot air dryers rotary vane, rotary vane can be biaxially dryer (vertical, horizontal), three-axis rotary vane dryer (horizontal), may be early, depending on the viscosity of sludge humidity below 85% moisture content material drying to a final moisture content below 12%, the drying time is short, typically 2-10 minutes. Due to high speed stirring vigorously stirred damp leaf material, wet material can be in contact with the hot air is good. The material in the first half of the machine fast evaporation of water, a sharp decline in temperature of hot air inside the machine, and therefore, even if the hot air temperature, temperature of the material is not high.
