Technical Field

[0001] The utility model relates to the technical field of waste heat power generation waste water treatment, in particular to a waste heat power generation waste water pretreatment device. Background Art

[0002] Cement rotary kiln belongs to the category of building materials equipment and is a type of lime kiln. According to the different materials processed, the rotary kiln can be divided into cement rotary kiln, metallurgical chemical rotary kiln and lime rotary kiln. Cement rotary kiln is the main equipment of cement clinker dry and wet production lines. A large amount of heat is generated during the cement calcination process, which can be converted into electrical energy for use.

[0003] Existing cement rotary kilns mostly use boilers to recover waste heat to generate electricity. However, after using the waste heat to generate electricity, the wastewater is mostly discharged after sedimentation treatment. However, after discharge, the sediment in the wastewater tends to clump and sink to the bottom, requiring manual cleaning by personnel, which causes inconvenience in operation and needs to be improved.
