Embodiment Construction

[0022] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment includes the filter mud outlet 1 connected to the plate and frame filter press device, the filter mud outlet 1 is connected to the crushing device 2, and the bottom outlet of the crushing device 2 is connected to the inlet of the fluidized bed drying device 4 through the conveying device 3, and the fluidized bed is dried The outlet at the bottom of the device 4 is connected to the inlet of the calcination device 5 through the conveying device 3 ; the calcination device 5 is connected to the fluidized bed drying device 4 through the waste heat recovery device 6 .

[0023] A crushing device 2 is added at the filter mud outlet 1 of the sugar workshop to crush the filter mud after the plate and frame filter press into large pieces, which facilitates the evaporation of water in the filter mud and reduces the energy consumption in the later calcination process; after crushing The f...

Abstract

The invention relates to the technical field of comprehensive utilization of industrial solid wastes and particularly discloses an efficient and comprehensive utilization method and device of filter mud for sugar making. The efficient and comprehensive utilization method of the filter mud for sugar making takes the filter mud for sugar making as a treatment object and is characterized in that after being crushed, the filter mud for sugar making is dried and then is conveyed into a high-temperature furnace to be calcined, wherein the calcining temperature is 900-1050 DEG C, and the calcining time is 20-30 minutes; finally, a calcium oxide product is obtained. The efficient and comprehensive utilization method and device disclosed by the invention have the benefits that steps are simple, the realization is easy, the difficult problem of treatment of a large amount of solid wastes-filter mud generated by sugar making by using a carbonation method is solved, wastes are changed into valuables, and the purpose of waste resource is achieved.

Description

[0001] (1) Technical field [0002] The invention relates to the technical field of comprehensive utilization of industrial solid waste, in particular to a method and device for efficient comprehensive utilization of sugar filter mud. [0003] (2) Background technology [0004] At present, the sugar industry adopts two cleaning processes, the carbonic acid method and the sulfurous acid method. The filter mud is raw sugar liquid and processing aids CaO and H 2 O and CO 2 Solid waste generated during the clarification process, which in the sugar industry is known as filling. Carbonation sugar production process is to generate CaCO through filling 3 Precipitation and adsorption to achieve the purpose of removing non-sugar substances in cane juice. There is a large amount of filter mud discharge in the production process, and there is still no thorough and effective treatment method. The treatment of white sugar (soft white sugar), a by-product in the production process of a lar...
