Description
Technical field
The present invention relates to haydite, be specifically related to the concavo-convex excellent activated carbon haydite filtrate of a kind of rubble shape.
Background technology
The active carbon specific area is big, and adsorption rate is fast, and degree of purification is high, is widely used in chemical industry, electronics, medicine, printing and dyeing, food and domestic water, water for industrial use, solution Filtration Adsorption purification and impurity removal and decolouring.But the active carbon quality of supplying on the market is loose, hardness is lower, and under the effect of external force, micropore easy blocking, distortion and shedding are difficult to maintain the original state, and the backwash water consumption that is used for water treatment is bigger, and the price of active carbon is higher.
Mineral Resources in China 80% is for being total to associated minerals, and a large amount of valuable resources retain among the mine tailing, and tailings impoundment need take a large amount of soils.Exceed the time limit in a lot of mine tailing storehouses or excess load is used, even violation operation, makes the mine tailing stock in great potential safety hazard, and the people's property and the life security of surrounding area caused serious threat.
Flyash is to receive the thin ash of catching the flue gas behind coal combustion; Flyash also is the main solid waste that the coal-burning power plant discharges; Be one of bigger industrial residue of the current discharge capacity of China, along with development of electric power industry, the flyash discharge capacity of coal-burning power plant increases year by year.A large amount of flyash does not add processing, will produce airborne dust, atmosphere pollution; If entering water system can cause the river to silt up, and toxic chemical substance wherein also can work the mischief to human body and biology.
Chinese patent publication number CN 1065603A, in open day on October 28th, 1992, name is called " activated carbon haydite compounded filter material and manufacturing approach ", discloses a kind of activated carbon haydite compounded filter material and manufacturing approach.This filtrate and preparation method's characteristics are, in the potter's clay that contains SiO2, Ai2O3, Fe2O3, CaO, MgO, add cork, hardwood flour or bone meal, are placed on that roasting increases the filtrate of processing behind its hole again in the airtight container.Its effect is similar with active carbon.
Report according to inventor's result of the test: according to the production method of above-mentioned patent; In the potter's clay that contains SiO2, Ai2O3, Fe2O3, CaO, MgO, add cork, hardwood flour or bone meal, be placed in the airtight container roasting and can not process " activated carbon haydite compounded filter material ".The weak point of above-mentioned patent is: various batchings " adding water fully mixes thoroughly "; In airtight container through 800～1100 ℃ of roastings after 5～18 hours; Because potter's clay and cork, hardwood flour and bone meal can not form an integral particle fully; Potter's clay is a kind of sand shape, and cork, hardwood flour and bone meal have become ashes mostly, can't process " activated carbon haydite compounded filter material ".
Summary of the invention
The objective of the invention is to overcome weak point in the prior art, provide a kind of rubble shape concavo-convex excellent activated carbon haydite filtrate.
Wood dust and the kaolin mine tailing of the concavo-convex excellent activated carbon haydite filtrate of rubble shape after by the sticking Concave-convex clay rod powder of height, Concave-convex clay rod mine tailing, flyash, anchracite duff, acidifying formed.
The production method of the concavo-convex excellent activated carbon haydite filtrate of rubble shape: the batching of the concavo-convex excellent activated carbon haydite filtrate of rubble shape is packaged as the concavo-convex excellent activated carbon haydite filtrate of rubble shape after mix, granulation, roasting, cooling, pulverizing and screening.
Concave-convex clay rod be a kind of layer of chain structure contain Shuifu County's zeopan clay mineral; The Concave-convex clay rod soil property is fine and smooth; Water imbibition is strong; Tool viscosity and plasticity help the bonding between the raw material when wet, can improve granule strength, adhesive force and the porosity of the concavo-convex excellent activated carbon haydite filtrate of rubble shape.
High sticking Concave-convex clay rod powder is meant gets 28.0g Concave-convex clay rod powder sample; Add in the suspension cup of homogenizer, add 372g water again, the suspension cup is placed on the homogenizer; Under 11000 rev/mins rotating speed, stirred 20 minutes; To pass through the high-speed stirred sample suspension again and pour in the beaker of 250ml, the viscosity of using NDJ-1 type rotation viscometer to test its suspension, tested viscosity value>=2200
MPasThe Concave-convex clay rod powder be high sticking Concave-convex clay rod powder, the height that the present invention selects for use glues Concave-convex clay rod powder particles fineness≤0.074 millimeter.
The soft easy dispersion suspension of kaolin matter in water, have good plasticity and higher caking property, the Al2O3 content in the kaolin is higher, the intensity that helps improving the concavo-convex excellent activated carbon haydite filtrate of rubble shape with reduce sintering temperature.
Concave-convex clay rod and kaolin can mix in recovery process has a certain amount of rubble and earth; Can't sieve; Abandon as a kind of mine tailing; Cause a large amount of wastings of resources, the present invention pulverizes Concave-convex clay rod mine tailing and kaolin mine tailing respectively and is mine tailing, grain fineness≤0.10 millimeter.
The flyash main component is silica, alundum (Al, di-iron trioxide, calcium oxide and uncompleted burned carbon, does not fire charcoal and is loose porous form more, the grain fineness of flyash≤0.10 millimeter.
Anthracite through the anoxic roasting form stable chemical performance behind the active carbon, mechanical strength is high, life cycle is long and stable performance, the grain fineness of anchracite duff≤0.10 millimeter.
The concavo-convex excellent activated carbon haydite filtrate of rubble shape is in roasting process; Wood dust after the acidifying of haydite extexine is ashes through the aerobic burning; Form a large amount of micropores; Roasting has generated a kind of high grade activated carbon to wood dust after the inner acidifying of haydite through anoxic, wood dust grain fineness≤0.10 after the acidifying millimeter.
The present invention is achieved through following technical proposals:
