Description
Key words: sludge dryer municipal sludge dryer sludge paddle dryer paddle dryer sludge treatment sludge dryer manufacturer
Classification: slime engineering industry
Case overview: paddle dryer is a kind of low-speed stirring dryer which is equipped with agitator in the equipment to make the wet materials fully contact with heat carrier and hot surface under the agitation of blades, so as to achieve the purpose of drying. Horizontal or four axis structure.
In recent years, under the influence of China's energy conservation and emission reduction policies and active finance, urban sewage treatment has been developed rapidly, and water environment treatment has also achieved remarkable results. However, the moisture content of a large number of sludge produced during sewage treatment is too high, which is above 80%, so it is impossible to carry out sanitary landfill or other final disposal. The sludge produced every day has no outlet, which seriously affects the normal operation of sewage treatment plants, causes great harm to the environment, and seriously affects the implementation of China's energy conservation and emission reduction strategy.
Our company introduced advanced sludge drying technology from abroad, combined with the actual situation in China to manufacture the municipal sludge special dryer, which can fully meet the requirements of the industry customers, and is trusted and cooperated by more and more enterprises. The new municipal sludge dryer produced by Haomai drying is a kind of low-speed stirring dryer with conduction heating. The jacket is set on the dryer cylinder, and A hollow blade is arranged on the hollow shaft, in which heat carrier is introduced. Under the agitation of the agitator blade, the wet material can fully exchange heat with the cylinder and the hot surface of the blade, so as to achieve the purpose of drying. At present, our company has cooperated with many large, medium and small enterprises in China to solve the technical problems in sludge treatment.
Structure principle of sludge dewatering and drying equipment for municipal sewage treatment
The equipment adopts conduction heating mode, which is composed of two blade shafts meshing with each other, W-shaped shell frame and transmission part. The whole drying process of sludge is carried out in a closed state, and the odor gas and moisture of organic volatiles are sent to the tail gas treatment unit through the induced draft device in the closed atmosphere, so as to avoid environmental pollution. The heating medium is steam and heat transfer oil. The heating medium is divided into two channels, which enter into the inner chamber of the blade and the interlayer of the drying shell respectively. The chamber and blade shaft are heated at the same time, and the sludge is dried by conduction heating. After the sludge enters the machine cavity, the sludge is turned over and stirred by the rotation of the paddle blade, and the heating interface is constantly updated to fully contact with the heated body and blades, so that a large amount of water in the sludge is evaporated. At the same time, the sludge is transported to the feeder with the rotation of the blade shaft, and the dried and even sludge is discharged from the outlet.
Application of dewatering and drying equipment for municipal sewage treatment sludge
The mixing blade is also the heat transfer surface, which increases the heat transfer area per unit effective volume and shortens the treatment time. The heat transfer surface of wedge blade has the function of self-cleaning. Compression expansion mixing function makes materials mix evenly. A kind of
Municipal sludge special dryer is suitable for paper sludge, printing and dyeing sludge, tanning sludge, electroplating sludge, oilfield sludge, domestic sludge, petrochemical sludge, activated sludge and other sludge drying. If you have sludge drying treatment and other aspects of the needs and technical questions, welcome to call us for advice, our company will thoroughly solve the sludge problem for you
