Sludge treatment device and method

Abstract

The invention relates to the technical field of sludge treatment, in particular to a sludge treatment device, which comprises a machine body sequentially provided with a feeding area, a dewatering area and a discharging area from top to bottom, wherein the dewatering area comprises a plurality of centrifugal dewatering cylinders arranged in the machine body, and a heating device is arranged in themachine body. The invention also provides a sludge treatment method which comprises the following steps: 1, firstly conveying sludge into a feeding area, distributing the sludge, and equally classifying the sludge into different parts for dehydration treatment; 2, dewatering the classified sludge through high-speed centrifugation; 3, heating the sludge during the dehydration process. When the sludge treatment device is used for treating sludge, the plurality of centrifugal dewatering cylinders can be used for dewatering the sludge at the same time, and the heating time can also be shortened and the energy is saved when the sludge is subjected to subsequent drying and heating while rotary dewatering is carried out.

Description

technical field [0001] The present application relates to the field of sludge treatment technology, in particular to a sludge treatment device and treatment method. Background technique [0002] With the construction of a large number of sewage treatment plants in my country and the continuous improvement and improvement of sewage treatment technology, sludge treatment has become an important link that must be given priority in the design and operation of sewage plants. Sludge dewatering equipment is used in municipal domestic sewage, river water, industrial sewage, etc. industry has been widely used. [0003] The most critical indicator of sludge treatment is the water content. At present, the methods of sludge treatment mainly include mechanical dehydration, thermal drying, anaerobic fermentation, incineration and so on. At present, the Chinese invention patent with the notification number CN103708690B discloses a sludge treatment equipment, including a sludge conveyor, a ...

AI Technical Summary

Problems solved by technology

[0004] For the above-mentioned related technologies, the inventor believes that there are following defects: the solid content and water content in the sludge are generally high, and when the sludge with high water content is processed, it takes a long time to process the sludge The moisture in the sludge is evaporated, and at the same time, the high temperature of the drying chamber needs to be maintained throughout the drying process, so it takes a lot of energy to process the same batch of sludge for a long time
