Embodiment Construction

[0019] Further description will be made below in conjunction with drawings and embodiments.

[0020] A cement kiln cooperative processing construction waste system and method in this embodiment, the system includes a cement kiln cooperative processing system and a construction waste processing system. The cement kiln synergy system mainly sends the regenerated aggregate of construction waste as cement raw material to the raw material mill, and the screened dregs are used as cement raw material. Construction waste treatment mainly consists of storage, screening, iron removal and crushing. The storage system is a closed yard 1. The construction waste is stacked in the closed yard 1 after entering the site. The capacity of the closed yard 1 can store construction waste for 7 days; the construction waste in the closed yard 1 is stacked by the loader 2. The storage system transports the construction waste out of the closed yard through the loader 2, and is connected with the apron...

Abstract

The invention discloses a system and a method for synergistically treating construction waste by using a cement kiln. The system comprises a cement kiln synergetic treatment system and a constructionwaste treatment system, wherein mainly aggregate obtained after construction waste regeneration is used as a cement raw material and is fed into a raw material mill in the cement kiln synergetic treatment system, screened residue soil is used as the cement raw material, and the construction waste treatment system mainly comprises a storage system, a screening system, an iron removal system, a crushing system and the like. According to the invention, by combining a construction waste treatment process and a cement production line, construction waste is treated through screening, classification,manual sorting, two-stage crushing, iron removal, dust removal and other processes, the sorted combustible materials (plastics, wood, paper, paperboards and the like) are conveyed into a waste incinerator, and the treated aggregate as a cement raw material is fed into a raw material mill; and the method and the system are suitable for national conditions of China, and are low in energy consumption, high in yield, scientific and reasonable.

Description

technical field [0001] The invention relates to the field of building material processing, in particular to a cement kiln co-processing construction waste system and method. Background technique [0002] my country produces a large amount of construction waste every year, accounting for more than 60% of the total waste. Most of the construction waste is piled up in the open air or landfilled without any treatment, which consumes a lot of land. The places where construction waste has been landfilled can never be recultivated, resulting in a serious waste of land resources. At the same time, problems such as dust, dust and sand flying in the process of clearing, transporting and stacking have caused serious environmental pollution. There are many ways to dispose of construction waste, such as landscaping, direct stacking, filling pits to create land, and resource utilization. Compared with other municipal wastes, construction waste has the characteristics of large amount, no...
