Embodiment 1

[0033]The invention provides an integrated device for sludge homogeneous slurrying and thermal hydrolysis reaction. A tank body 1 is provided with a feed port 2 and a discharge port 3 at the upper and lower parts of the tank body 1 respectively. The port 2 and the discharge port 3 are respectively connected with a first sealing member and a second sealing member; the first agitator 4 is located in the tank body 1 and includes a first agitating shaft 41, the first agitating shaft 41 protrudes from the top of the tank body 1 and is connected to the first driving mechanism, and the shaft seal between the first stirring shaft 41 and the tank body 1; also includes several steam ports 5 distributed in the tank body Body 1, used to pass steam into the tank body 1; the second agitator 6, located in the tank body 1, includes a second stirring shaft 61, and the second stirring shaft 61 extends out of the tank The bottom of the body 1 is connected with the second driving mechanism, and t...

Embodiment 2

[0046] Such as figure 2 As shown, this embodiment provides an integrated device for sludge homogeneous slurrying and thermal hydrolysis reaction, which is an improvement made on the basis of Embodiment 1. Compared with the technical solution of Embodiment 1, it is different The only thing is that: the several steam ports 5 are evenly spaced and located at the same height on the tank body 1; connected, and the annular steam pipe 7 is provided with several steam outlets, at the same time, the steam outlet is arranged in a hole shape, preferably a round hole shape, and the steam outlets are in two rows on the annular steam pipe 7, And uniformly arranged, of course, the steam outlet can also be set in other hole shapes and other positions on the annular steam pipe 7 .

Embodiment 3

[0048] Such as image 3 As shown, this embodiment provides an integrated device for sludge homogeneous slurrying and thermal hydrolysis reaction, which is an improvement made on the basis of Embodiment 1. Compared with the technical solution of Embodiment 1, it is different Only in that: the several steam ports 5 are evenly spaced, and some of the several steam ports 5 are located at the same height on the tank body 1; A steam port 5 communicates with the annular steam pipe 7 arranged close to the inner wall of the tank body 1, and the annular steam pipe 7 is provided with several steam outlets, and at the same time, the steam outlet is arranged in a hole shape, preferably a circular hole shape, and the steam outlets are in two rows on the annular steam pipe 7, and are evenly arranged. Of course, the steam outlets can also be set in other hole shapes and other positions on the annular steam pipe 7 .

[0049] The following is the use method of the sludge homogeneous slurrying...

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...
