With the continuous growth of the urban population and the rapid development of industrial production, the amount of urban domestic sewage and industrial wastewater is increasing. In order to protect the ecological environment, urban wastewater must be treated and discharged before reaching the standard. However, when the sewage is purified, a large amount of sludge is generated. Since the sludge has high water content and a large volume and is characterized by various toxic and harmful substances, if it is not safely disposed of, It will bring serious secondary pollution to the environment. Under normal circumstances, the mechanical dewatering technology of sludge can only reduce the moisture content of sludge to about 80%. Such high water content is not conducive to the subsequent transportation and disposal of sludge. Therefore, in order to effectively treat and recycle the sludge, the sludge drying process is indispensable.
The machine is a box structure, and a multi-layer conveyor belt is arranged in the box, and the conveyor belt circulates in the box. The material is evenly distributed on the first conveyor belt. Through the transmission of the chain, the first layer of the mesh belt is poured into the next layer of the mesh belt, and the lower layer is alternately dropped one by one to the last layer of the mesh belt. At this time, the moisture content of the material meets the drying requirements. The air circulation adopts a countercurrent process, and the high temperature and low humidity airflow upward from the lowermost mesh belt of the dryer to carry out mass transfer heat transfer, thereby achieving the purpose of removing moisture, and the exhaust gas is discharged from the top through the induced draft fan. The equipment has a high degree of automation, and the materials are automatically turned over during the drying process to ensure uniform drying of the materials. It has the advantages of low labor intensity, a good working environment, and simple equipment maintenance. The bottom of the box is designed with a blanking swash plate and a quick opening cleaning door to facilitate the cleaning of the powder in the box.
1. The air volume, heating temperature, material residence time, and feeding speed can be adjusted to achieve the drying effect;
2. The equipment configuration is flexible, and the belt washing system and material cooling system can be used;
3. Most of the air is recycled, which saves energy;
4. The double-layer air circulation structure is adopted, the hot air is even, and there is no partial dry phenomenon;
5. According to the characteristics of the material, different process flow and additional auxiliary equipment can be added;
6. Fast-drying speed and high evaporation intensity;
7. The mesh belt has good gas permeability and the drying cycle can be arbitrarily adjusted;
8. According to customer needs, it can be divided into several units, each unit can control the loop separately.
9. There are various heat source selections, such as steam heating, electric heating, heat transfer oil heating, hot air heating, etc.
