Abstract

The invention relates to a sludge homogeneous slurrying and thermal hydrolysis reaction integrated device which comprises a tank body, a plurality of steam ports arranged on the tank body, and a first stirrer and a second stirrer which are arranged in the tank body; by arranging the plurality of steam ports on the tank body, the steam ports are used for introducing steam into the tank body, and thus a certain temperature and pressure are formed in the tank body; moreover, by rotation of the first stirrer and the second stirrer, a sludge material is subjected to rapid and uniform heat and mass transfer, same-speed or differential-speed stirring, same-direction or reverse-direction stirring and various combined stirring ways can be achieved, and shearing, wall scraping and other functions are achieved; in addition, with combination of a steady flow force of the steam, the sludge material is easy to turn over and / or easy to roll over in the tank body, and besides, under the action of the double stirrers, no dead corner exists, and the uniformity of slurrying and thermal hydrolysis reaction are further promoted.

Description

technical field

[0001] The invention relates to the technical field of sludge treatment devices, in particular to an integrated device for sludge homogeneous slurrying and thermal hydrolysis reaction. Background technique

[0002] In 2011, my country promulgated the "Technical Guidelines for Sludge Treatment and Disposal of Urban Sewage Treatment Plants (Trial)" and introduced the water treatment technology for the remaining sludge after sewage treatment as follows: The hydrothermal treatment technology is to heat the sludge at a certain temperature and pressure. It is a technology that hydrolyzes the viscous organic matter in the sludge, destroys the organic colloidal structure of the sludge, and modifies the dehydration performance and anaerobic digestion performance, also known as thermal conditioning. Hydrothermal treatment technology divides hydrothermal treatment into thermal hydrolysis and wet oxidation according to whether an oxidant is added during the treatment proc...
