Description
Technical field:
The invention belongs to a kind of method and device that materials recycling utilizes that will be in the super-cell production process produce.
Background technology:
Useless filter aid is the filter aid that loses filtration that unloads by on the multiple filters such as plate and frame, rotary drum, the common name filter cake.In the filter aid filter process, organic matters such as the impurity in the liquid being filtered, cotton-shaped colloid, yeast, the micropore obstruction with filtration in the filter aid loses filtration, as hazardous waste.The processing of useless filter aid has dual mode basically: the one, unload on the spot from filter that water washes out, and discharge the tank that factory fixes outward or be discharged in the rivers and lakes by drain way; The 2nd, transport outside the factory strange land and throw away or pile and abandon.But no matter handle, all can cause the pollution of surrounding enviroment, water quality, air and the waste of resource with what mode.Especially heap is abandoned processing, because of the effect of yeast, can make the organic matter fermentation in the useless filter aid, rots soon to foul in warm season, makes us suffocating.Along with the development of instrument food industry, used super-cell also day by day increases, and the useless filter aid that brings therefrom also increases year by year.Only beer production is increased to 3,000 ten thousand tons of 2003 for 2,800 ten thousand tons by less than in 2002.Calculate by ton beer mean consumption 1.4Kg super-cell, the sector was just thrown away the useless filter aid more than 4.2 ten thousand tons in 1 year.And all use the every profession and trade of super-cell, throw away useless filter aid and have 100,000 tons more than in 1 year.This shows the wasting of resources that the waste diatomite filter aid brings, how serious it is that environmental pollution that causes and heap are abandoned the land occupation amount.
And about 200,000,000 tons of China's diatomite geology commercial reserves that it has been established that, about 200,000 tons of year yield.Under year yield situation about not increasing, the existing diatomaceous commercial reserves of China can be exploited 100 years.Resource can not be regenerated, if there is not new diatomite mineral ore to find, will do not have diatomite the next century and can exploit utilization.
The application's device is the device (number of patent application: the improvement of carrying out on the basis 200420011404.2) for preparing filter aid at patent application diatomite.
Technology contents:
Shortcoming and the problem of the present invention in order to solve above-mentioned existence provides and produces waste diatomite filter aid regeneration method and the device that materials recycling utilizes in a kind of super-cell production process.
Method of the present invention is:
A, at first filter cake is sent into centrifuge dewatering, carry broken feeding machine fragmentation through belt conveyor again, broken back filter cake is sent into strong drying machine drying by the duplex tube helix conveyer, and further is broken into powder;
The negative pressure that b, powder are produced by blower fan through adjustable grader sucks cyclone separator and carries out the separation of vapour material, and granular material is discharged by the discharger of cyclone separator below and reclaimed, and enters the filter aid production routine;
C, cyclone separator include the gas of micronic dust by sack cleaner dedusting, purification, and the gas emptying purifies the fines that intercepts and discharges recovery by the screw machine of sack cleaner below, enters the filter aid production routine.
The hot vapour that the present invention enters in the strong drying machine is that filter aid production process rotary kiln produces tail gas.
When the tail gas that rotary kiln of the present invention produces is not enough, can be by adding hot-air.
Device of the present invention is made up of centrifuge, conveyer belt, broken feeding machine, strong drying machine, one-level grader etc., the strong drying machine is connected with cyclone separator by pipeline, the cyclone separator upper end is connected with sack cleaner by pipeline, and the cyclone separator lower end is connected with the one-level grader by discharger.
Rotary kiln of the present invention is connected with pipeline between the one-level grader with strong drying machine and cyclone separator respectively by pipeline.
The present invention has not only solved the regeneration problem of waste diatomite filter aid, the pollution and the wasting of resources of also having avoided the waste diatomite filter aid to cause to environment.Make Limited resources obtain fully effectively utilizing.Be suitable for the trivial reduction utilization of regeneration of the useless diatom ground filter aid that industries such as beer, liquor, fruit wine, syrup, beverage and mineral water discard.Also be suitable for moisture diatom ground original soil below 50% and directly carry out filter aid production without giving drying.The waste diatomite filter aid can repeat regeneration reducing with method and apparatus of the present invention and utilize more than six times.
Description of drawings:
Accompanying drawing is a structural representation of the present invention.
The specific embodiment:
Waste diatomite filter aid regeneration method of the present invention is:
At first moisture waste diatomite filter aid filter cake (waste diatomite filter aid) more than 80% is sent in the centrifuge, make it dehydration to moisture about 50%, carry broken feeding machine fragmentation through belt conveyor, broken back filter cake is sent in the strong drying machine by the duplex tube helix conveyer.Enter useless filter aid in the strong drying machine and be ground into granule once more less than 0.1mm through the grating disk of rotation at a high speed, granule rotates under eddy flow that is produced and the double action that is produced steam flow by machine top grader at the rotation grating disk, form the lifting steam flow that suspends and rotate and move up and down, the suspended particulate of this steam flow is finished heat exchange at the volley with the hot vapour that enters interior about 500 ℃ of machine.Granule is finished moisture reducing to≤5% after the heat exchange, and is powdered.
B, powder reach the critical granularity that needs by the steam flow pulverizing once more of adjustable grader, and the negative pressure that is produced by blower fan sucks cyclone separator.Not reaching proceeding to of critical granularity reaches till the adaptation particle diameter.Enter the interior vapour material vapour material of cyclone separator after separating, granular material is discharged by the discharger of cyclone separator below and is reclaimed, and enters the filter aid production routine.
C, cyclone separator include the gas of micronic dust by sack cleaner dedusting, purification, and the gas emptying purifies the fines that intercepts and discharges recovery by the screw machine of sack cleaner below, enters the filter aid production routine.
The hot vapour that the present invention enters interior about 500 ℃ of strong drying machine is about 300 ℃ the tail gas that filter aid production process rotary kiln produces, and the tail gas heating system of forming through burner, heat-exchanging furnace produces, and tail gas can replenish air when not enough.
Waste diatomite filter aid regeneration device of the present invention is made up of centrifuge 1, conveyer belt 2, broken feeding machine 3, strong drying machine 4, one-level grader 9 etc., strong drying machine 4 is connected with cyclone separator 5 by pipeline, cyclone separator 5 upper ends are connected with sack cleaner 7 by pipeline, and cyclone separator 5 lower ends are connected with one-level grader 8 by discharger 6.
Rotary kiln 9 is connected with the pipeline of strong drying machine 4 with 8 in cyclone separator 5 and one-level grader respectively by pipeline.A valve can be installed on pipeline, be used to control the gas flow of the pipeline that enters 8 in strong drying and cyclone separator 5 and one-level grader.
Whole production apparatus system of the present invention is to operate under negative pressure, and material stream passed is unobstructed.Be equal to the filter aid of producing with diatomite original soil fully by its physical and chemical index of super-cell and performance that the present invention regenerated.
