Abstract
The invention discloses a method for producing lime by using waste Nan'an marble powder. The method comprises the steps of collecting waste marble powder in the stone industry in a classified mode; piling, drying and homogenizing the marble powder in a classified mode in a piling shed; shaping applicable marble powder directly or by granulating, and then feeding the marble powder into an industrial kiln for calcination, wherein marbles are decomposed in the kiln through calcination to generate high-quality burnt lime with small particle size, high porosity and high activity, and the lime is further used for producing lime derivative products. The method is characterized in that a wet powdery material is adopted and is subjected to light burning and fast burning to prepare active lime, so that the method is favorable for reducing the consumption of natural limestone mine resources. According to the method disclosed by the invention, waste marble powder generated by the stone industry is used for producing lime and downstream derivative products of the lime, so that the problem of pollution caused by the discharge of waste stone powder in the stone industry can be effectively solved, the waste stone powder can be digested and saved, the sustainable development of the stone industry is promoted, and the method is of great significance of improving environmental protection and economic benefit.

Marble flour is the cutting powder that stone slab source mill produces when cutting saw marble material, and in working angles, its crystal under saw blade extruding of the stone material in marble saw kerf is damaged, and forms the powder that fineness is little, surface-area is huge.Can produce more than 200 ten thousand tons of discarded marble flours our province Nanan head town year, the accumulation of stone flour not only land occupation but also contaminate environment, cause direct impact to the Sustainable development of stone material industry.By Nanan's marble flour is carried out to physical and chemical experiment analysis: chemical composition and the Wingdale of marble flour are basically identical, only difference to some extent on crystalline structure, Wingdale belongs to microcrystal or undefined structure, and marble crystallization degree is high, crystal is fine and close, and reactive behavior is little.According to its chemical constitution and physical properties, research and develop a kind of novel process and technology of utilizing discarded marble flour to produce quickened lime, make the utilization that obtains dissolving of a large amount of discarded marble flours, significant to realizing the comprehensive utilization of solid waste.
Summary of the invention
Activity of Lime is the important indicator of weighing lime calcining quality, and its product price and use range thereof are had to considerable influence.The object of the present invention is to provide a kind of method of utilizing the discarded marble flour of Nanan to produce quickened lime, make the utilization that obtains dissolving of discarded marble flour, realize the Sustainable development of Ornamental Stone Industry.
For achieving the above object, the present invention adopts following technical scheme:
A kind of method of utilizing the discarded marble flour of Nanan to produce lime, by the discarded wet-milling shape marble flour categorised collection of Ornamental Stone Industry, in heap canopy, classify and store up, after drying, homogenizing, by marble flour directly or after granulation formation, feed Industrial Stoves calcining, marble is CaO and CO through calcining and decomposing in kiln
2, the lime generating after decomposing is discharged after supercooler is cooling, deposits in airtight lime reservoir.
Described marble flour fineness is 0.02 ~ 0.1mm.
Described disposal be by dissimilar marble flour through categorised collection, oven dry, homogenizing, guarantee that the calcium carbonate content in marble flour is 90%.
Described granulation formation is in marble flour, to add admixture, adopts mechanical pelleting, and marble flour is a granulated into piece, forms spherical, block material, and fragmentation Control is at 20 ~ 150mm;
Described admixture comprises lime, gypsum, sulfonated lignin.
It is calciner that described Industrial Stoves adopt suspension kiln, shaft furnace or rotary kiln, and calcining temperature is controlled at 900 ~ 1150 ℃.
The reaction the present invention relates to is as follows:
CaCO
3→CaO+CO
2
Remarkable advantage of the present invention is:
(1) utilize first the discarded marble flour of Nanan as raw material production lime.Mass-producing comprehensive utilization to the discarded marble flour of Nanan, solves the pollution problem that stone flour discharges, and guarantees that the Sustainable development of stone material industry is significant, and will produce huge ecological benefits and economic benefit.
(2) the present invention is according to the feature of the discarded marble flour of Nanan, by techniques such as categorised collection, oven dry, homogenizing, granulations, suit measures to local conditions to utilize original state powder raw material to carry out quickened lime calcining, production technology and equipments can guarantee the quality technology requirement of marble flour active lime calcination, the quickened lime making is a kind of high-quality soft burnt lime, have that particle is little, void content is high, active high, avoid the step of ordinary method crushed stone lime stone simultaneously, reached useless, the energy-saving and cost-reducing object of profit.
(3) be conducive to reduce the exploitation in natural limestone mine, reduce the consumption of limestone mine resource, and alleviate the environmental problems such as vegetation deterioration that cause thus.
