The Three-stage Multi-loop Dryer (with disintegrator) for domestic sludge is an energy-saving, consumption-reducing and eco-friendly drying equipment developed by ZJN Drying System Co., Ltd. It can adapt to various drying needs of different industries and meet the drying requirements of high-moisture, high-viscosity, solid waste and hazardous waste sludges. During the drying process, it makes full use of heat energy, accelerates heat and mass transfer, improves drying speed, and reduces heat energy loss at the same time.
The drum of the equipment is made of wear-resistant and high-temperature-resistant stainless steel, ensuring a long service life. The skilled manufacturing technology of ZJN's technical personnel enables the equipment to give full play to its performance, extend the service life of some accessories, and ensure stable and reliable operation with low failure rate. It is one of the professional drying equipment on the market.
The structure of the entire domestic sludge dryer is as follows:
1."Triple-cylinder" nested structure, that is, the drum is composed of three nested concentric cylinders. The advantage of this design is that the length of the dryer main body is shortened to only one-third of the original, which not only saves the factory space but also enhances the thermal insulation effect. This compact structure is featured by its space-saving and energy-efficient characteristics, which is consistent with the design concept of modern environmental protection equipment.
2. A "rotary rake crushing" device is installed inside the drum, which can break materials into small particles according to different material sizes, facilitating the increase of the contact area between sludge and hot air, thereby accelerating the drying speed. Combined with the built-in combined material lifting plates, the sludge keeps moving at high speed reciprocally in the drum. While accelerating the sludge drying, it also prevents the sludge from sticking together due to "loss of activity", helping users solve the drying problem of high-moisture and high-viscosity materials. The rotary rake device and material lifting plates work together to ensure uniform drying and avoid sludge agglomeration.
ZJN Drying System Co., Ltd., founded in 1991, has adhered to independent innovation for more than 30 years and focused on the research of drying technology. It has successively developed several drying technologies, including the "Three-stage Multi-loop Dryer (with disintegrator)" series for high-moisture and high-viscosity domestic sludge, the "triple-drum multi-pass grid type" pulp series, the "automatic raking reciprocating multi-loop" steam utilization series, the "boiler waste heat drying utilization" technology, and the "low-temperature high-airflow" drying technology. The company is committed to providing users with new types of energy-saving and environmentally friendly drying equipment.
