Abstract
A process for preparing the activated argil with high desorptive and decoloring power is prepared from the Hangjing clay are No.2 through immersing in water to become sludge, adding hydrochloric acid, activating by heating it to 90-100 deg.C, water rinsing, dewatering, baking and pulverizing (more than 200 mesh).
Description
Technical field
The present invention relates to a kind of production method of atlapulgite, refer in particular to and adopt wet processing to produce the method for atlapulgite.
Background technology
At present, the method for domestic production atlapulgite generally is that bentonite is formed with sulfuric acid heat-activated processing.Domestic quality is atlapulgite preferably, as: enemy mountain, Zhejiang bentonite ore is a underground mining, and the atlapulgite of production is better, and product quality is: specification CS-1024; Decolorizing ability 〉=110; Free acid≤0.2%.But along with economy and development of science and technology, the application of atlapulgite is more and more wider, and existing production method can not satisfy domestic demand.Develop and a kind ofly realize that the method for comprehensive utilization of resources, low-cost production atlapulgite is necessary.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of production method of atlapulgite.This production method adopts wet processing.
Technical problem of the present invention is solved by following scheme: the production method of atlapulgite, comprise system mud, and heat-activated is handled, and slurry divides acid, washing, dehydration, stoving process process, it is characterized in that Hanggin 2
#Clay pit coarse crushing system mud, is 2～3: 1 mixing with 12～16% hydrochloric acid solutions with liquid-solid ratio, 90～100 ℃ of heat-activated 3.5～4h, do not stop to stir, absorb spent acid gas with limewash, adopt and divide acid, washing, each amount of water is 5～6 times of original soil, being washed till washing lotion pH value reaches 5～6 and gets final product, 100～105 ℃ of oven dry 2～2.5h in the drying box are sent in pulp centrifuged dehydration after the washing to, are ground into through cooling and promptly get atlapulgite more than 200 orders, above-mentioned limewash is absorbed the absorption liquid and the 1st of spent acid gas, 2 rinsing liquids and mother liquor merge, with limewash neutralization precipitation Fe (OH)
3, filter the Fe (OH) that obtains
3Filter cake, oven dry 450～500 ℃ of roastings in back get iron oxide red, and the filtrate evaporation and concentration gets CaCl
2NH
2O, the steam cooling water-recovering.3rd, 4 times rinsing liquid is used for soaking the use of raw material soil system mud circulation.
Advantage of the present invention is: the present invention is with Hanggin 2
#Clay pit is that raw material is produced atlapulgite, Hanggin 2
#The clay pit reserves are abundant, with low cost, have extensive use.Premium properties such as it has that natural particle size is thin, specific area is big, inhale that blue ability is strong, absorption, decolouring, ion-exchange and Heat stability is good.Through complete chemical analysis and X-ray diffraction quantitative analysis results such as table 1 and table 2.
