Petrochemical sludge refers to the sludge from the grease trap, flotation tank scum, and bottom mud of crude oil tanks during the refining process. It is commonly known as [three muds". These oily sludges are of different composition and usually contain oil. Between 10% and 50%, the moisture content is between 40% and 90% with a certain amount of solids. Because petrochemical sludge causes serious environmental pollution to nature, it is one of the major pollutants of petrochemical enterprises.
Our company has more than 20 years of experience in manufacturing
Drying Equipment. According to this environmental protection issue, our company designed and manufactured a special paddle
Dryer for petrochemical sludge. The dryer is a conduction heating low speed stirring dryer. The heat medium flows through the blade through the hollow shaft, and the heat transfer area per unit volume is large. The heat medium can be water vapor or liquid type, such as hot water, heat transfer oil and the like. Indirect conductive heating, without carrying air to take away heat, heat is used to heat the material. The heat loss is only through the body heat insulation layer to the environment. The wedge blade heat transfer surface has a self-cleaning function. The relative motion of the material particles and the wedge-shaped surface creates a scrubbing action that can wash away the adhered material on the wedge surface so that a clean heat transfer surface is maintained during operation.
