What is the working principle of domestic sludge dryer

With the continuous increase of domestic water consumption of residents, the amount of sewage treatment also increases. As a "derivative" of sewage treatment, the annual output of sludge is increasing year by year. The huge demand for sludge treatment and disposal has led to the rapid development of the whole sludge industry. Various types of domestic sludge dryers have emerged in an endless stream in the drying market, such as belt dryer, single drum dryer, fluidized bed dryer, disc dryer, paddle dryer, ZJN domestic sludge dryer and so on. Among them, ZJN domestic sludge dryer adopts a new drying structure and energy-saving drying process, which is widely used in the domestic sludge recycling project. It can improve the quality of finished products, control the processing cost, and improve the market competitiveness of products, and promote the enterprise benefit and income.

Working principle of domestic sludge dryer

In view of the high humidity and high viscosity domestic sludge drying process, the new type of domestic sludge dryer changes the appearance and internal structure of the traditional single drum dryer, and adopts the "three sleeve" inlaid structure, the rotary rake crushing device, and the scientific distribution of the combined lifting plate device, which can effectively dry the high humidity and high viscosity sludge.

The wet sludge enters the cylinder of domestic sludge dryer, and with the rotation of the cylinder, the wet sludge continuously falls under its own gravity. The "rotary rake crushing" scattering device set in the cylinder continuously breaks and breaks the materials into fine particles. Under the action of the combined lifting plate, it gradually scatters and scatters, and forms a uniform material curtain on the cross-section of the cylinder. At this time, the high-temperature air flow passes through the cylinder The temperature difference between the material and the hot air is too large, which causes the sludge to heat up and quickly evaporate a large amount of water. In the process of lifting, scattering and repeated for many times, the sludge can fully exchange heat with hot air. After drying, the sludge becomes loose material with low moisture content and is discharged from the outlet.

Aiming at the domestic sludge with high wet viscosity, a real energy-saving domestic sludge dryer was built, and a variety of scientific and reasonable drying processes were adopted. Not only effectively improve the drying technology, but also ensure the quality of equipment. In the dazzling drying market, only concentrate on the field of drying, and do a good job in the production, research and development and manufacturing of sludge dryer. In order to achieve the goal of win-win cooperation, we should not take inferior products as good ones, do not engage in vicious price competition, do not disturb the market order, and take honesty as the foundation.
