Abstract

The invention relates to a sludge drying and dewatering system based on disk drying. The sludge drying and dewatering system comprises a disk drying system and a press drying system. The disk drying system comprises a shell, wherein a stirring shaft is arranged in the shell; disk pieces are arranged on the stirring shaft at an interval; the top of the shell is provided with a sludge inlet and a steam outlet, and the bottom of the shell is provided with a dry sludge outlet; the stirring shaft is driven by a motor located at one end of the stirring shaft; the stirring shaft is of a hollow structure; and one end of the stirring shaft is a hot steam inlet, and a condensed water outlet pipe is inserted into the hot steam inlet. The press drying system comprises a press filtration system, and a sludge feeding system, a vacuum-pumping system, a hot water circulating system and a sludge output system all connected with the press filtration system, wherein the sludge feeding system is connected with the sludge inlet end of the press filtration system; the sludge output system is connected with the sludge outlet end of the press filtration system; the vacuum-pumping system is used for maintaining the press filtration system in a negative pressure state during press filtration of sludge; and the hot water circulating system is connected with the steam outlet of the disk 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 ...
