Abstract

The invention discloses a solid waste treatment device of a cement kiln, which structurally comprises a stepped furnace (5), wherein a solid waste and hazardous waste feed opening (6) is formed in the upper plane of the stepped furnace (5), a tertiary air distribution port (8) is formed in the front side surface of the stepped furnace (5), the rear side surface of the stepped furnace (5) is communicated with a kiln tail decomposing furnace (3), the lower surface of the stepped furnace (5) is in a stepped shape, and the inclined direction of the stepped shape is from the tertiary air distributing port (8) to the kiln tail decomposing furnace (3) and is from high to low. By the adoption of the technical scheme, the solid waste and hazardous waste treatment device is additionally arranged beside the kiln tail decomposing furnace, solid waste and hazardous waste are pre-disposed before entering a firing system, and the influence of the solid waste and hazardous waste on the firing system is reduced; and meanwhile, the disposal capacity of the solid waste and hazardous waste is improved, and recycling, harmless disposal and reduction disposal of the solid waste and hazardous waste are achieved.

Description

technical field

[0001] The invention belongs to the technical field of comprehensive utilization of resources in cement production, and relates to solid and hazardous waste treatment and recycling technologies. More specifically, the present invention relates to a solid waste disposal device for a cement kiln.

[0002] The invention relates to a stepped calciner for co-processing solid and hazardous waste in a cement kiln, and belongs to the technical field of solid and hazardous waste disposal. With the help of solid waste and hazardous waste disposal equipment outside the cement kiln, the time for calcination and decomposition of solid waste and hazardous waste outside the kiln is extended, the moisture in solid waste and hazardous waste is reduced, and the impact on the kiln calcination system is reduced. At the same time, the heat of solid waste and hazardous waste is fully utilized value, and realize the harmless, resourceful and reduced disposal of solid waste and haz...
