Description
Technical field
The present invention relates to microbial fertilizer technical field, it is specifically related to a kind of composite microbial manure taking useless clay mineral as main raw material.
Background technology
Decoloration process in edible fat production process generally uses carclazyte, Attapulgite, perlite. Carclazyte main component is silicon-dioxide, also containing calcium, the elements such as magnesium. Carclazyte is canescence particle powder, has bigger specific surface area and Kong Rong, has special adsorptive power and ion-exchange performance, has stronger decoloring ability and activity, and decolouring rear stability can be good. It is mainly used in petroleum industry, Unstable Substance and the coloring matters such as the unsaturated hydrocarbons of the petroleum-type mineral such as paraffin, lubricating oil, sulfide, colloid and bituminous matter can be adsorbed. Generally, carclazyte is often referred to atlapulgite and acidic white earth. Atlapulgite is raw material with clay (mainly wilkinite), through inorganic acidifying process, then through sorbent material that water rinse, drying are made, outward appearance is off-white powder, without smelly, tasteless, nontoxic, absorption property is very strong, can adsorb coloring matter, organic substance. The easy moisture absorption, placed and can reduce absorption property for a long time in atmosphere. But, it is heated to more than 300 degrees Celsius and just starts to lose crystal water, structure is changed, affects fading effect. Atlapulgite is insoluble in water, organic solvent and various oils, is almost dissolved in completely in hot caustic soda and hydrochloric acid, relative density 2.3��2.5, and in water and oil, swollen profit is minimum. Atlapulgite is extensively for the decolorizing and refining of mineral oil, animal-plant oil, wax processed and organic liquid; Also can be used as moisture drying agent, endo-medicine alkaline hydrolysis toxic agent, vitamin A, B sorbent material, lubricating oil coincidence contact substance, gasoline gas phase finishing agent etc.; Also can be used as middle temperature polymerizing catalyst, high temperature polymerization agent and manufacture the raw material of granular carclazyte.
Attapulgite, also known as polygorskite (Palygorskite) or Palygorskite, is the moisture rich zeopan clay mineral of a kind of tool chain laminate structure. Its structure belongs to 2:1 type clay mineral, and in each 2:1 unit structure layer, tetrahedron wafer angle is pushed up direction at a certain distance and put upside down, form layers chain shape. Forming the passage parallel with chain between tetrahedron band, channel cross section is about 3.7*6.3A ��, filling zeolite water and crystal water in passage. Attapulgite soil goods after processing are ideal sorbent material, food processing aid and foodstuff additive, can replace gac. It can not only decolour, also can deodorizing taste removal, removing heavy metals ion and carcinogenic substance, also there is certain selectivity, this is just for production is provided convenience, it can make deodorant for refrigerator, sewage-treating agent, household water filter, oil and fat refining discoloring agent, and effect is very obvious, pharmaceutically can make the filler of medicine, carrier, additive, binding agent. Using attapulgite soil that by 12 procedures of Powdered Activated Carbon purification, Liquid Glucose decolouring can be reduced to ten procedures, process cycle shortens 50 minutes, very favourable to developping production. With the commerieal sugar of attapulgite soil purification, its color and luster, figure, concentration, reducing sugar content, PH value, sulfurous gas ion content, chloride content, protein content, sugar cook temperature and calcium ions and magnesium ions content etc. all reach existing industry standard, save desolventing technology expense about 60%, filter cake after decolouring can make mixed fodder, decrease environmental pollution, reach comprehensive utilization.
No matter being in adsorption process, or in sewage disposal, attapulgite soil can regenerate, its power consumption is few, and environment protection is highly beneficial. The order of attapulgite soil adsorption selection ability size is: water > alcohol > acid > aldehyde > positive alkene > neutral fat > aromatic hydrocarbon > naphthenic hydrocarbon > alkane, straight chain hydrocarbon adsorbs soon than branched-chain hydrocarbon, and the decolouring of grease is had important effect by adsorption selectivity. Other sepn process also has bigger industrial value.
For the spent bleaching clay after edible oil decolouring use or useless attapulgite soil, such useless clay, up to about 18-22%, is squeezed in the industry by usual oleaginousness usually, obtains grease. Technique is generally first steam useless clay with high-temperature steam, clothes afterwards, it may also be useful to oil cylinder squeezes, oil-water mixture of squeezing out. Oil-water mixture being introduced slurry tank and carries out twice sedimentation, oil-water separation, by Grease Collection, water then returns to beginning and is heated as steam. Water circulation use, not effluent.
But grease wherein still cannot thoroughly be removed by above-mentioned technique. The useless clay oleaginousness about 5% of generally final two times. For this kind two useless clays, due to still oil-containing, can not arbitrarily abandon, otherwise environmental pollution can be caused. Not having good Land use systems at present, mainly burning disposal, enterprise needs usually using the cost of every ton about 100 yuan as handling.
