What are the characteristics of sludge dryer in environmental protection steel plant?

Steel making and iron making enterprises produce a large amount of sludge every day. In view of the pollution problem of sludge in steel plants, more and more enterprises choose to introduce several environmental protection sludge dryers after consulting and inspecting the ZJN equipment. This equipment has the characteristics of energy saving and consumption reduction, clean and dry, and no mud can be seen in drying process. It can dry mud, flake, sticky and other high humidity and high viscosity materials, effectively solving the problem of sludge disposal in steel plant.

So far, there are many real engineering cases of sludge dryer of "rotary harrow three-cyclinder multiple-loop" steel plant produced by ZJN, and have won good reputation among users. For large and medium-sized steel-making plants, in addition to meeting the needs of daily drying production, the operation cost of equipment is the more concerned problem. Low drying cost saves a lot of expenses for the enterprise, which is conducive to enhancing the competitiveness of the enterprise. Then how can we know whether the sludge dryer in the steel plant is really energy-saving? According to the relevant experience of the research and development, production and manufacturing of the dryer in the past 30 years, the following briefly summarizes the characteristics of the sludge dryer in the environmental protection steel plant.

1. Low heating cost

Heating cost is the main part of equipment operation cost. Reducing heating cost can greatly reduce equipment operation cost. Steel making and iron making enterprises can use "boiler waste heat" to replace more expensive natural gas, gasoline and other fuels.

2. The equipment has good thermal insulation

The material selection and manufacture of the equipment also affect the operation cost. "Three sleeve" inlaid structure is adopted in the sludge dryer of ZJN, and the cylinder wall is made of stainless steel with high temperature resistance and wear resistance, which has good heat preservation and sealing performance and small heat loss of equipment.

3. Drying process

Good drying process can improve the drying efficiency with half the effort, such as "low temperature and large air volume", "DC vortex plus AC reciprocating", "three cylinder multi return network format", etc. Good process can ensure the quality of finished products, keep the surrounding environment clean, and greatly increase the utilization rate of heat energy, and accelerate the drying speed of sludge dryer in steel plant.
