Description
（One）Technical field
The present invention relates to industrial solid castoff technical field of comprehensive utilization, more particularly to a kind of sugar mill mud high-efficiency comprehensive utilization
Method and device.
（Two）Background technology
Using carbonatation process and sulfurous method both cleaning procedures in current sugar manufacturing industry production, filter mud is that raw sugar liquid is helped with processing
Agent CaO, H2O and CO2The solid waste produced in clarifying process, the process is referred to as full charge in sugar manufacturing industry.Carbonatation process is refined sugar
Technique is to generate CaCO by full charge3Precipitation adsorption effect, with reach removal sugarcane juice in non-sugar material purpose.Produced
Filter mud discharge capacity is big in journey, at present still without thorough, effective processing method, white granulated sugar（Soft white sugar）This large agricultural and sideline product
The treatment of accessory substance in product production process, has a strong impact on and constrains the healthy, quick of sugar industry, sustainable development, make its into
For the hang-up that sugar manufacturing industry faces.The filter mud main component that carbonatation process sugaring is produced is calcium carbonate（CaCO3）, its content
（Butt）It is 80%-85%, containing organic matters such as a small amount of carbohydrates, also including a small amount of magnesium carbonate（MgCO3）, silica（SiO2）, three
Al 2 O（Al2O3）, iron oxide（Fe2O3）Deng mineral matter.
（Three）The content of the invention
The present invention is in order to make up the deficiencies in the prior art, there is provided a kind of step is simple, improve energy utilization rate, and reduction is produced into
This sugar mill mud high-efficiency comprehensive utilization method and device.
The present invention is achieved through the following technical solutions：
A kind of sugar mill mud high-efficiency comprehensive utilization method, is process object with sugar mill mud, it is characterised in that：The sugar mill mud
It is dried after crushing, is then fed into high temperature furnace calcining, calcining heat is 900-1050 DEG C, and calcination time is 20-30min,
Finally obtain oxidation calcium product.
The filter mud that the present invention produces carbonatation process sugaring produces the calcium oxide of high-quality by high-temperature calcination（CaO）, so that
The treatment problem of sugar mill mud is solved, there is huge realistic meaning to current severe environmental pollution situation, technology warp
Ji, society and environmental benefit are notable.
More excellent technical scheme of the invention is：
The sugar mill mud is the solid slag that the refined job shop of sucrose is produced after raw sugar liquid passes through plate-frame filtering, is contained
The moisture of 20-40%, in bulk, bulk footpath is up to 20cm, and sugar mill mud is homogeneous, particle diameter integrated distribution 30-70 μm it
Between, account for gross mass 84.9% of particle diameter less than 80 μm, account for gross mass 4.1% of particle diameter more than 100 μm, under hot conditions easily
Decompose.
The waste heat that the sugar mill mud high-temperature calcination is produced is delivered to drying section, improves energy utilization rate, reduces production
Operating cost.
The device of the method for the invention is realized, including the filter mud of connection sheet frame filter-pressing device is exported, it is characterised in that：Institute
Filter mud outlet connection breaker is stated, the outlet at bottom of breaker connects fluidized bed drying device entrance by conveying device,
The outlet at bottom of fluidized bed drying device connects calciner plant entrance by conveying device.
The calciner plant connects fluidized bed drying device by waste-heat recovery device, realizes the transmission of waste heat.
After the present invention crushes sugar mill mud, it is dried, into high temperature furnace calcining after drying, by adjusting calcining heat
And the time, filter mud is decomposed into calcium oxide and carbon dioxide, the calcium oxide of generation is a kind of Chemical Manufacture raw material of high-quality,
Can be processed with reuse to sucrose, complete the high-efficiency comprehensive utilization of filter mud.
Step of the present invention is simple, easily realizes, solves carbonatation process sugaring and produces the treatment of a large amount of solid waste-filter muds difficult
Topic, turns waste into wealth, and has reached the purpose of changing waste into resources.
（Four）Brief description of the drawings
The present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of apparatus of the present invention.
In figure, 1 filter mud outlet, 2 breakers, 3 conveying devices, 4 fluidized bed drying devices, 5 calciner plants, 6 waste heats are returned
Receiving apparatus, 7 products.
（Five）Specific embodiment
Accompanying drawing is a kind of specific embodiment of the invention.The embodiment includes the filter mud outlet 1 of connection sheet frame filter-pressing device, described
Filter mud outlet 1 connects breaker 2, and the outlet at bottom of breaker 2 connects fluidized bed drying device 4 and enters by conveying device 3
Mouthful, the outlet at bottom of fluidized bed drying device 4 connects the entrance of calciner plant 5 by conveying device 3；The calciner plant 5 passes through
Waste-heat recovery device 6 connects fluidized bed drying device 4.
Breaker 2 is added at sugaring workshop filter mud outlet 1, by the filter mud bulk crushing after plate and frame filter press press filtration, just
