Description

Technical Field

[0001] This utility model relates to the field of wet sludge steam drying, and in particular to a wet sludge steam drying device for sludge brick making. Background Technology

[0002] Sediment discharged from wastewater treatment structures. Sediment mainly composed of organic matter is called sludge. It is characterized by easy putrefaction and odor, fine particles, low specific gravity (approximately 1.02–1.006), high water content and difficulty in dehydration, and is a hydrophilic substance with a colloidal structure.

[0003] Sludge typically has a moisture content of over 99%. Directly making bricks from sludge results in a large amount of residual moisture inside the bricks, affecting the molding effect and subsequent firing quality. Steam drying can effectively reduce the moisture content of sludge, allowing it to reach the plastic state required for brick making.

[0004] Existing wet sludge steam drying devices for sludge brick making mostly adopt single-stage steam injection or static contact methods, and lack a waste heat recovery structure during the drying process. This not only easily leads to heat waste, but also causes wet sludge to accumulate in clumps, making it difficult for steam to penetrate the interior, resulting in uneven drying.

[0005] Therefore, it is necessary to provide a wet sludge steam drying device for sludge brick making to solve the above-mentioned technical problems. Utility Model Content

The other ends of the two conveying pipes are connected to the two first steam jet structures respectively. The steam generator is used to generate high-temperature steam.

The spiral conveyor structure 21 can transport the sludge from one end of the drying frame 5 to the other end. During this process, it can be dried by high-temperature and high-pressure steam, allowing the sludge to dry during the transport process. The other ends of the two conveying pipes 24 are respectively connected to the two first steam jet structures 7.

During this process, the screw conveyor structure 21 rotates and drives the sludge to move slowly towards the discharge pipe 6. During the movement, the high-temperature steam will gradually dry the wet sludge, and the waste heat will be recovered and injected into the interior of the drying frame 5 near the sludge inlet 22 through the second steam jet structure 9 to preheat the wet sludge and prevent the surface from hardening due to high temperature.
