Sewage treatment sludge drying furnace

Abstract

The invention discloses a sewage treatment sludge drying furnace which comprises a drying furnace body. The drying furnace body comprises an outer furnace barrel and a trumpet-shaped inner furnace barrel assembled in the outer furnace barrel. The trumpet-shaped inner furnace barrel comprises a left conical part and a right conical part. A middle part is arranged between the left conical part and the right conical part, and a mounting piece is assembled on the middle part. The mounting piece comprises a fixed disc sleeve fixedly connected to the middle part, a plurality of U-shaped mounting seats are fixedly connected to the disc outline of the fixed disc sleeve, and the U-shaped mounting seats are assembled on the outer furnace barrel through a plurality of assembly bolts in a threaded mode. The device further comprises a plurality of flow guide components assembled in the trumpet-shaped inner furnace barrel. Each flow guide component comprises a fixed ring body rod, and a plurality of annularly distributed leaf-shaped flow guide sheets are fixedly connected to each fixed ring body rod. A material grinding component is fixedly connected into the trumpet-shaped inner furnace barrel, and the drying furnace body is communicated with a pyrolysis gas inlet component. By adopting the device component design, the pyrolysis processing efficiency of materials is effectively improved.

Description

technical field [0001] The invention relates to the field of sewage treatment devices, in particular to a sludge drying furnace for sewage treatment. Background technique [0002] Sewage is the wastewater produced in the process of industrial production and agricultural production. Wastewater contains a large amount of organic matter, microorganisms and other polluting substances. Therefore, sewage needs to be recycled before it can be recycled. In the sewage treatment process, the sewage needs to be flocculated, settled and other operations, and the settled sludge waste can be processed into industrial materials such as activated carbon through pyrolysis and carbonization. [0003] In the pyrolysis process of sludge processing, the sludge material needs to be fed into the pyrolysis gas into the rotary furnace for pyrolysis, and the dried sludge is formed through the pyrolysis process, and the activated carbon is processed through the subsequent carbonization operation of th...

Problems solved by technology

[0006] At the same time, during the pyrolysis process, the material gradually dries and the humidity gradually decreases. The particle size of the dried sludge material gradually decreases during the rotation process, and the agglomeration gradually decreases. However, during the pyrolysis process, part of the material Failure to fully contact the pyrolysis gas causes the material to remain agglomerated. Most of the furnaces disclosed in the prior art use a stir-fry board in the furnace, but the stir-fry board can only stir-fry the material. For small agglomerated materials, the stir-fry The board doesn't fry it enough
