Remixing process of dry pulverized coke and wet pulverized coke of coke making raw material

Abstract

The invention relates to a process for re-preparing the coking waste of dry coke powder and wet coke powder in a coking plant. The process comprises the following steps: (1) a working procedure of mixing the dry coke powder and the wet coke powder, during which according to proportion, the dry coke powder enters to a dry and wet material blender through a speed regulation rotary valve; the wet coke powder with water content of between 40 and 45 weight percent enters the dry and wet material blender through the transportation of a 1* number belt conveyer; and the dry coke powder and the wet coke powder are evenly mixed to obtain a coke powder mixture with the water content of less than or equal to 10 weight percent; and (2) a working procedure of adding the coke powder, during which the coke powder mixture is transported to a middle feed bin through a serpentiform conveyer; according to the requirement of the re-preparing amount, the coke powder mixture enters a 3* number belt conveyer through a speed regulation spiral conveyer and is transported to a working procedure of coking. The process solves the problem of comprehensive utilization of the dry coke powder and the wet coke powder of the coking waste, makes waste profitable, saves energy, improves the environmental and sanitary conditions of the coking plant and increases economic benefit.

Description

technical field [0001] The invention relates to a process flow of a remixing device for waste dry coke powder and wet coke powder, in particular to a remixing process for coking waste dry coke powder and wet coke powder in a coking plant. Background technique [0002] Some dry coke powder will be produced in the coking gas production process of the daily coking plant, which will be obtained through the dust collector collection system. The wet coke powder is discharged into the sedimentation tank by the coke oven using wet dust removal, and the wet coke powder is picked up from the pool by a grab crane and piled up to dry. The moisture content of the wet coke powder after sprinkling is 41.7% by weight. Originally, the dry coke powder and the wet coke powder were processed by takeaway methods. Environmental friendly. In order to solve the outlet problem of waste coke powder in the factory, the inventors of the present application designed a new process of mixing dry and wet...
