How to choose suitable low temperature sludge drying equipment

With the continuous progress of science and technology, more and more drying manufacturers introduce high-tech into sludge drying equipment to improve energy-saving and environmental protection of the equipment, which not only solves the problem of sludge treatment for users, but also creates more economic benefits for users. There are many types of low-temperature sludge drying equipment on the market, which causes a lot of trouble for the majority of users to choose low-temperature sludge drying equipment.

When users choose low-temperature sludge drying equipment, many manufacturers will ask about the characteristics of drying sludge, which refers to the moisture content, viscosity, treatment capacity and heat source of sludge, which is to better design a more suitable equipment scheme for users.

Because of the different water content, the type of equipment selected has great difference. If the moisture content of sludge is high, if the sludge is directly dried, then a lot of heat energy will be consumed and the production cost will be increased, which is not cost-effective. Therefore, it is necessary to dewater the sludge with large water content. The user's dewatering equipment will control its moisture content in a certain range before drying. This not only saves energy consumption, but also provides drying efficiency greatly.

Different viscosity, the process of low temperature sludge drying equipment selected is also very different. Because of the high viscosity of the sludge, it is easy to stick and agglomerate during the drying process. The drying process should be adjusted according to its viscosity. Generally, for the sludge with high viscosity, special crushing and lifting device will be installed inside the equipment barrel, which can well disperse and separate the sludge, accelerate the drying efficiency of the sludge and ensure the quality of the dried sludge.

The treatment capacity determines the specification and model of low temperature sludge drying equipment. In other words, the larger the size of the equipment, the greater the processing capacity; the smaller the specification, the smaller the processing capacity. If the treatment capacity is small, and choose the equipment with small specifications and models, it will cause waste of thermal energy resources and high production cost. Otherwise, it will not be able to meet its production needs.

At present, the heat sources of low-temperature sludge drying equipment include coal, gas, oil, electricity, biomass heat sources, steam and boiler flue gas waste heat resources. Different heat sources will have different heat source devices. When selecting equipment, we also need to pay attention to the material and performance characteristics of the equipment. Different materials, the quality of the equipment manufactured is also very different, which not only affects the performance of the equipment, but also affects the service life of the equipment.

In a word, when users choose low-temperature sludge drying equipment, they need regular manufacturers to purchase and communicate with manufacturers in detail about the characteristics of materials and production requirements, so that manufacturers can ask you to design a reasonable equipment scheme to ensure the quality of the equipment, so as to create more economic benefits for users.
