Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a sludge dryer for water service sewage treatment. Background Art

[0002] Most sewage sources usually come from domestic sewage, industrial sewage and agricultural sewage. In order to protect the quality of the water environment, sewage usually needs to be treated to a certain extent so that it can meet the discharge standards, including pretreatment, biological treatment and deep treatment. At the same time, a certain amount of sludge will be produced in the process of sewage treatment. The sludge produced usually needs to be dried to reduce the water content of the sludge, so as to facilitate subsequent landfill and other treatments of the sludge.

[0003] A sludge dryer is a device used to dehydrate and dry sludge. Existing sludge drying equipment includes hollow paddle dryers and rotary drum dryers. The hollow paddle dryer uses steam, hot water or thermal oil as the heating medium. The heating medium enters the jacket of the dryer shell and the inner cavity of the paddle shaft, heating the dryer body and the paddle shaft at the same time, heating and drying the sludge by conduction. The sludge contacts the body and paddles, and the moisture evaporates. In the rotary drum dryer, the material is fed into the rotating cylinder through a feeding device, and contacts and mixes with the hot air flow entering from the same end. Under the rotation of the lifting plate, the hot air flow fully contacts the sludge, causing the moisture in the sludge to evaporate.

[0004] Taking into account the limited space inside the existing paddle-type sludge dryer due to the presence of the blades during use, sludge is easily accumulated inside the machine or attached to the blades, which can easily lead to increased wear of the blades and uneven sludge drying. During the drying process of the rotary drum dryer, the residence time of the sludge in the drum may vary due to various factors, resulting in uneven moisture content of the dried product. The sludge near the feed port and the discharge port may have different degrees of drying, which will also affect the drying effect of the sludge, thereby reducing the use effect and work efficiency of the sludge dryer.
