Abstract
The regeneration technique of diatomite filter-aid includes the following steps: using waste filter residue as main material; adding auxiliary material according to a certain proportion; uniformly mixing them; feeding them into drying stage of reaction calcining furnace successively to remove water content; oxidizing and carbonizing organic material in thermal decomposition stage; completely oxidizing in high-temp. oxidizing stage; sintering in fluxing calcination stage; discharging from furnace, breaking and sorting, and regulating grain size; making the material in the furnace backflow with hot air. The recovery rate of diatomite filter-aid is 90%, and the utilization rate of diatomite is raised by above eight times. It can save resource, and can reduce pollution, and is applicable to waste filter residue containing diatomite, organic material, fungi and carbon, etc. as regeneration material.
Description
The regeneration techniques of super-cell belongs to a kind of production method of super-cell.
Super-cell has good chemical stability, and is pollution-free to filtrate, can use on all kinds filter at various media.Super-cell is widely used in fields such as beer, chemical industry, medicine, food, water treatment at present.Its consumption increase is very fast, and production scale constantly enlarges, but the production of super-cell to want the diatomite mineral reserve of a large amount of consume valuable be main material.Use the back to discharge a large amount of filter residues and all throw away with discarded object, not only wasted resource but also contaminated environment, product cost is also very high.Do not find the patent identical by retrieval with the present invention.
The objective of the invention is: it is the new technology that main material is produced super-cell that a kind of useless filter residue that produces with used super-cell is provided.Solve waste resource and environmental pollution problem.
Technical scheme of the present invention is: to contain the useless filter residue of organic super-cell is major ingredient, and being equipped with corresponding oxidant in proportion is auxiliary material, and mixing is transported to the dryer section of reaction calcining furnace and removes moisture content.Continue heating to the thermal decomposition section, the organic matter thermal decomposition produces fuel gas by the oxidation of airborne oxygen institute, and organic impurities is by charing.To high-temperature oxydation section excessive oxygen supply time the rising temperature, make the abundant oxidation of charcoal, remove impurity.At last at the calcining section sintering of fluxing.The fragmentation that discharges out of the furnace then, granularity is adjusted in sorting.Material and hot blast reverse flow in the stove.Because super-cell uses organic matter in the useless filter residue that the back produces, mushroom, charcoal etc. easily to decompose when high temperature and by airborne dioxygen oxidation, generate the water of gaseous state, carbon dioxide and a spot of sulphur, oxides such as nitrogen are discharged, and diatomaceous chemical analysis is constant substantially, can readjust size distribution through flux calcining and sorting, thereby realize the regeneration of super-cell.
The present invention's regeneration super-cell rate of recovery from useless filter residue can reach more than 90%, and filter aid uses regeneration again and again again and again through using a regeneration ... cyclic process to make the diatomite utilization rate improve octuple many.Economize on resources, reduce environmental pollution, reduce production costs.Be applicable to that its composition mainly is a diatomite, the useless filter residue of organic matter, mushroom and charcoal etc. is as regenerative raw materials.
Accompanying drawing: auxiliary equipment and reaction calcining furnace general structure generalized section.
Embodiment carries out in conjunction with the accompanying drawings: the filter residue of getting glucose saccharifying liquid is that major ingredient A other composition except that containing diatomite mainly is an albumen.Active carbon after carbohydrate and the decolouring etc.The hydrogen peroxide of adding 0.1% is that auxiliary material B mixes in proportioning machine 11, enter hopper 12 is sent to material the reaction calcining furnace from feeding gate 2 by feeder 13 dryer section 1, in stove, transfer the wind bubbling air by pulling out bin gate 3, and be interrupted to stir and quicken drying, do not pull out gradually into thermal decomposition section II to not working energetically at 5% o'clock to moisture content.500-800 ℃ of rising temperature, the excessive wind of giving is interrupted and stirs, and makes material decomposing oxidation and charing, pulls out gradually into high-temperature oxydation section III.Further intensification 800-1000 ℃, excessive wind and the interruption of giving stirred, and the oxidation carbon removal is finished.Pull out into the calcining compartment 6 of calcining section IV and finish sintering 1000-1100 ℃ the time from pulling out bin gate 3.Enter disintegrating machine 14 through discharge door 5, it is grade packaged to send into sorter 15 minutes after the fragmentation.Burning stops up 8 by fire door 7 adding fuel, and to the combustion chamber blowing-in and combustion-supporting, flame and flue gas are discharged from having every the chimney 1 in road through flue 4 through blower fan 10 airducts 9.The gas cyaniding thing that impurity decomposing oxidation in the material produces is discharged from another passage of chimney.
Claims (1)
- The regeneration techniques of 1 super-cell comprises that batching, calcining, classification etc. is characterized in that: to contain the useless filter residue of organic super-cell is major ingredient, being equipped with corresponding oxidant in proportion is auxiliary material, and mixing is transported to the dryer section of reaction calcining furnace and removes moisture content; Continue heating to the thermal decomposition section, the organic matter thermal decomposition produces fuel gas by the oxidation of airborne oxygen institute, and organic impurities is by charing; To high-temperature oxydation section excessive oxygen supply time the rising temperature, make the abundant oxidation of charcoal, remove impurity; At last at the calcining section sintering of fluxing; The fragmentation that discharges out of the furnace then, granularity is adjusted in sorting; Material and hot blast reverse flow in the stove.
