Abstract

The invention relates to a sludge drying and dewatering system based on disc drying, including a disc drying system and a filter press drying system. The disc drying system includes a shell in which a stirring shaft is installed. Discs are installed separately on the stirring shaft. The top of the shell is provided with sludge inlet and steam outlet, and the bottom is provided with dry sludge outlet. The stirring shaft is driven by a motor at one end. The stirring shaft is a hollow structure, and one end is a heat sink. The steam inlet is inserted with a condensed water outlet pipe; the filter press drying system includes a filter press system, a mud inlet system connected to the filter press system, a vacuum system, a hot water circulation system, and a sludge output system. The mud inlet system is connected to the mud inlet end of the filter press system, and the sludge output system is connected to the mud outlet end of the filter press system. The vacuum pumping system is used to maintain the negative pressure state when the filter press system presses sludge, so The hot water circulation system is connected with the steam outlet of the disc drying system.

Description

technical field [0001] The invention relates to the field of sludge treatment equipment, in particular to the technical field of sludge drying, in particular to a sludge drying and dehydration system based on disk drying. Background technique [0002] A large amount of sludge will be produced after urban domestic sewage treatment. If the sludge cannot be treated in a timely, effective and stable manner, it will bring great hidden dangers to the urban environment and the safety of people's lives. In addition, industrial processes such as papermaking, chemical industry, tanning, printing and dyeing, and dredging of rivers and lakes will also produce a large amount of sludge. [0003] The reduction and harmlessness of sludge has become a major environmental protection problem that must be solved in the process of urban scientific development. The moisture content of the sludge produced in the sewage treatment plant is still as high as 80% after dehydration, and the volume and ...
