Description

Technical Field

[0001] The utility model relates to the field of sludge treatment, in particular to a novel sludge drying treatment device. Background Art

[0002] In current industrial production and daily life, a large amount of sludge is often generated. At present, the landfill method is often adopted, that is, the sludge is transported to a special landfill site, buried underground and covered with an anti-seepage layer and a corrosion-resistant covering. However, this method wastes a large amount of land resources, is prone to pollute groundwater, and the volatilized gas pollutes the air. Therefore, a mechanical compression dehydration method appears, such as a vertical high-pressure belt type sludge deep dehydration machine for dehydration combined with a drying device for drying treatment. This can efficiently and continuously treat sludge. Its defects are as follows: First, the inside of the drying device is heated by a horizontal hot air flow, with a high temperature at the front end and a low temperature at the rear end. Since the sludge particles often contain a certain amount of moisture, it is easy to have uneven drying, which affects the drying effect, reduces the drying efficiency at the same time, and the uniformity of the dried product is poor. Second, the sludge has a high moisture content, is easy to adhere, not easy to break, and is prone to block the device, causing the device to stop in the middle, reducing the output of the device. Third, during sludge drying, a crusher is used for primary crushing, and the particles entering the second crushing in the disperser are relatively large. The moisture content inside the larger sludge blocks is high, and it is not easy to perform secondary crushing, further reducing the drying efficiency. Summary of the Utility Model
