Abstract
The present invention relates to a preparation method of light shale filter aids, which comprises the processes of the predrying, the burn and the pulverization of raw materials. The used raw materials are 55 to 80% of light shale and 20 to 45% of diatomite; firstly, water content of the raw materials is reduced to below 2%; at the temperature of 800 to 1200 DEG C, the raw materials are burned and treated; finally, the raw materials are milled into powder. A filter aid manufactured by the method of the present invention has the advantages of low cost, little energy consumption, good product filter effect, etc. The product of the present invention can be widely applied to the fields of wine brewing, beverages, medical sanitation, petrochemical engineering, water treatment, etc.
Description
The present invention relates to a kind of manufacture method of porous material, also relate to a kind of manufacture method of filtering material.
Mainly contain super-cell and pearlite filtering aid at employed filter aids in field such as wine brewing, beverage, medical and health, petrochemical industry, water treatments.With the immediate prior art of the present invention be the manufacture method of super-cell.Diatomite is a kind of fossil that is formed by diatom, has microcellular structure, and its Main Ingredients and Appearance is SiO
2, be the ideal material of making filter aid.The manufacturing of super-cell mainly wrap raw material pulverizing, drying, fire the technical process such as pulverizing with finished product.
Though the diatomaceous reserves of China are abundanter, can be also few as the high-quality product of making the filter aid raw material, and belong to " chicken coop ore deposit " more, and production ratio is difficulty, and dressing expenses is than higher.Contain a large amount of moisture content and other easy scaling loss composition in the diatomite, the ratio that raw material can change into finished product only is 50%.In order to remove moisture content and easy scaling loss composition, must strengthen pre-dried and improve firing temperature etc., must consume a large amount of energy like this.Therefore the cost of super-cell is generally all than higher.The composition that also contains clay in addition in diatomite, these clays are difficult to remove in sintering procedure, thereby cause micropore not smooth, influence the rate of filtration and quality.
The object of the present invention is to provide that a kind of cost is low, energy consumption is little, the manufacture method of the filter aid of good filtration effect.
The present invention seeks to realize like this: light shale with 55～80% and 20～45% diatomite are raw material, earlier the water content in the raw material are reduced to below 2%, fire under 800～1200 ℃ temperature, wear into powder at last.
The invention has the advantages that:
1, adopting light shale is primary raw material, and it is little that it has proportion, low, the easy fragmentation of hardness, characteristics such as clay content is low, water content is little.Can reduce energy consumption with it as the raw material of making filter aid, significant loss is few, (per 100 tons of raw materials can make 85 tons of filter aids).On China's Heilongjiang Province's Nehe, Nenjiang and other places, the light shale layer thickness of distribution reaches 0.5～1 meter, and exploitation is convenient.Therefore, its cost of filter aid that adopts method of the present invention to make only is 65～70% of super-cell.
2, because the reduction of firing temperature has prevented the appearance of the vitrification phenomenon of micropore surface effectively.Improved the filter quality of product.
3, to adopt the tail gas of ablating work procedure fully be thermal source raw material predrying, reduced energy consumption.
For example the present invention is done detailed description below
1, raw material consists of Nenjiang, light shale 70%(Heilongjiang Province and produces), diatomite 30%, light shale makes its granularity reach 100 orders after fragmentation, carry out pre-dried, drier is a thermal source with the tail gas of ablating work procedure, be dried to water content and be no more than 2%, deliver to batcher then, join in the mixer.Mixed raw material adopts wind-force to be transported to ablating work procedure, adopt rotary kiln to fire processing, rotary kiln divides preheating section and calcining section, preheating section is heated to raw material more than 300 ℃, calcining heat is 850～950 ℃, calcination time is 1-2 hour, carries out the abrasive dust processing then and wears into the powdered finished product.The prepared product of this technology is commonly referred to dry product.
2, raw material consists of Nenjiang, light shale 70%(Heilongjiang Province and produces), diatomite 30%, light shale is through fragmentation.Drying makes its water content less than after 2%, mixes to send in the rotary kiln and fires, and rotary kiln preheating section is with more than the raw material preheating to 300 ℃, and the temperature of its calcining is 950～1150 ℃, and calcination time is 1～2 hour, clays into power then.The prepared product of this technology is commonly referred to the calcining product.
3, raw material consists of light shale 70%, diatomite 30%.Make its water content less than after 2% after light shale, diatomite are broken respectively, predrying, add the flux that is no more than raw material total amount 8%, flux is the mixture of sodium carbonate, sodium chloride, borax, send in the rotary kiln then and fire, rotary kiln preheating section is preheating to more than 300 ℃, the temperature of its calcining section is 960～1150 ℃, and calcination time is 1～2 hour, wears into powder then.The prepared product of this technology is commonly referred to the flux calcination product.
