As a kind of solid waste, sludge has become the second largest source of solid waste pollution in urban garbage. The main disposal methods of traditional sludge include landfill, incineration, sea discharge, and agricultural use. However, the traditional treatment methods also have some drawbacks. They cannot utilize the sludge for resource utilization and cannot meet the technical requirements for sludge treatment. Therefore, it is of great practical significance to develop new technologies for sludge treatment and resource utilization. The treatment and disposal of sludge should be comprehensively considered from the aspects of environmental pollution, health and safety and economic benefits. The new sludge treatment technology with energy recovery and utilization will play an irreplaceable role in sludge treatment and disposal.
What is good for wastewater sludge drying equipment? Characteristics of sludge microwave drying equipment:
1. Short drying time, high efficiency, low drying temperature and uniformity, can maintain the composition, color and original flavor of the original materials. 3, selective heating, even and thorough. Since the water molecules are absorbed by the microwave, the portion having a high water content absorbs more microwave power than the portion having a lower water content. This is the characteristic of selective heating. With this feature, uniform heating and uniform drying can be achieved. 4. Energy saving and high efficiency. The microwave acts directly on the material, so there is no additional heat loss. Compared with energy saving of more than 30%, no waste is produced in the whole drying process. 5, microwave drying equipment using tunnel structure, PLC automatic control, automatic temperature control system, video surveillance system, transmission belt automatic correction system, transmission frequency control system, real-time monitoring, one-button setting, system automatic, simple operation The labor intensity is low; the equipment is mainly made of stainless steel plate, which has strong heat insulation performance and corrosion resistance, saves energy, works well, and has long service life.
Microwave drying equipment is practical, cost-effective; easy to control, convenient and flexible to operate, less manual use; saves time, high output; low energy consumption; low production intensity, small footprint; environmentally friendly and clean. No air pollution, no pollutants; easy to control, advanced technology. Compared with the conventional method, the device is ready to use; without thermal inertia, the operation is flexible and convenient; the microwave power is adjustable.
