Description
Technical field
The utility model relates to a kind of filter plant, is specifically related to the filter plant after the secondary charcoal absorption decolouring in the anhydrous dextrose production process.
Background technology
In the production process of DEXTROSE ANHYDROUS, material can mix a small amount of coloring matter and other impurity, has certain color, in order to guarantee the quality of final DEXTROSE ANHYDROUS, need decolour to material.The operating process of existing technology is: filter the material that comes through rotary drum and enter bleacher, add active carbon in accordance with regulations, stopped at least 30 minutes, make active carbon fully be absorbed with color substance, and detect protein content＜0.10%.Decolouring feed liquid well makes active carbon separate with liquid glucose again through being pumped into filter, and filtrate clarification back is with being pumped into basin before handing over.Filter residue can form filter cake in filter, along with filter cake thickens, the pressure of filter raises gradually, when reaching maximum pressure, need get rid of slag, and washing and filtering and inside, reactivates.
Prior art generally adopts the plate and frame filter as filter plant, since its filter capacity a little less than, need often get rid of slag operation, be unfavorable for carrying out continuously of whole technology, contain the Glucose Liquid material, the feasible excessive not easy to clean of filter residue viscosity that gets rid of the slag gained owing to be mingled with some in the filter residue, in the process of cleaning, need to consume a large amount of pure water, need a large amount of steam in the removal process again, not only waste energy but also reduced ultimate yield, caused bigger economic loss to enterprise.
Summary of the invention
Have above-mentioned deficiency at prior art, the utility model provides the filter plant behind a kind of secondary decolourization, makes to get rid of that slag is more easy to have reduced the loss of getting rid of Glucose Liquid in the slag process simultaneously.
Filter plant provided by the utility model has following characteristics: comprise housing, the top of housing is that cylindric bottom is gradually little round table-like of diameter, the housing of round table-like part is connected with discharge nozzle, feed pipe and slag dumping pipe from the top down respectively, all has valve on each pipeline; Vertical discharging axle is arranged on the position, axis of housing, this discharging axle bottom and discharge nozzle flexibly connect, the top of housing is equipped with motor, vertical discharging axle is connected with machine shaft and can rotates with motor, be set with at least two screen cloth dishes on the discharging axle, the top of screen cloth dish is screen cloth, and the order number of screen cloth can be identical also can successively increase with the discharging axle from bottom to top, and the interior cavity of the cavity in the screen cloth dish and discharging axle is communicated with; Lower housing portion has Drainage pipe at feed pipe and slag dumping pipeline enclosure, and the import of this Drainage pipe has filter screen.The screen cloth disc area is identical.The diameter of screen cloth dish is less than the bottom surface diameter of cylindrical shell.
When carrying out the filtration of the decolouring back material second time, by feed pipe material is sent into this filter plant, because the diameter of screen cloth dish is less than the bottom surface diameter of cylindrical shell, material is full of whole filter by the space between screen cloth dish and housing, material is filtered under the pressure of mass transport, filtrate enters in the cavity of screen cloth dish by screen cloth, cavity by the discharging axle enters discharge nozzle and discharges and enter the bottom operation again, active carbon and other impurity are left on the screen cloth, when the filter residue on every layer of screen cloth gathers to a certain degree, reach specified maximum pressure in the filter, need get rid of slag operation this moment, before getting rid of slag operation, close the pipe valve of slag dumping pipe and feed pipe earlier, open the valve switch of discharging tube, send back to residue liquid glucose in the device in the bleacher of decoloration process by discharging tube, filter screen by the discharging tube import before entering pipeline filters liquid glucose, oarse-grained impurity and active carbon are leached, when no filtrate when discharging tube is discharged, close the discharging tube valve, open slag dumping tube valve and motor switch simultaneously, driven by motor discharging axle and screen cloth dish rotate, filter residue on the screen cloth dish is thrown out of and leaks down from the space between screen cloth dish and housing under the action of the centrifugal, enter the slag dumping pipeline and send into previous albumen filtering technique by the slag dumping pipe, liquid glucose after albumen filters is being sent back to and is continuing in the treatment process to handle, the active carbon of gained returns to decoloration process, and all the other filter residues are discharged.
The maintenance in general supporting for convenience and later stage can all be used the identical screen cloth of order number with every layer, and the number of screen cloth is about 280 orders; But in order to make the impurity content in the gained filtrate lower, the effect of filtering is more obvious, sieve number on every layer of screen cloth dish can successively increase from bottom to top with the discharging axle, be generally the 260-300 order, when the order number was higher than 300 orders, screen cloth is as easy as rolling off a log to be stopped up by filter residue, caused that the equipment internal pressure is excessive to cause danger to production, and need the frequent slag that gets rid of, what influence was produced carries out continuously; When order number during less than 260 orders; active carbon that some are tiny or contaminant particles can enter the bottom operation with filtrate by screen cloth, cause the obstruction of equipment, and what influence was produced normally carries out; therefore the order number with screen cloth is limited to the 260-300 order, and the order number is successively increased from bottom to top with the discharging axle.
The filter that adopts the utility model to provide can filter out the active carbon and the impurity of different-grain diameter, improves greatly than the filter efficiency of existing plate and frame filter, and can successively clean between screen cloth when washing in to equipment, and effect is more obvious; When getting rid of slag since device interior pressure greater than the pressure of discharging tube, the self gravitation effect of liquid glucose in addition, liquid glucose can flow into discharging tube automatically and not need additionaling power; Drainage pipe is arranged at feed pipe and slag dumping pipeline enclosure, can avoids liquid glucose to enter other pipeline, can be with other line clogging.
Because filter plant of the present utility model has adopted above-mentioned structure, improved the effect of filtering, make that but getting rid of the material major part that remains in the equipment before the slag gets back in the bleacher, thereby no longer arrive the albumen filtering technique with filter residue, reduced processing step, yield is improved greatly, because the content of glucose reduces in the filter residue, make the viscosity of filter residue descend greatly, made things convenient for follow-up slag and the lock out operation of getting rid of.Make like this and get rid of slag carbon slurry amount at every turn and not only lacked 2/3rds, and it is few to contain glucose amount, the hammer degree descends 3 times, and viscosity also reduces greatly, and anhydrous like this carbon slurry also is not easy the plugging road.Adopt this device back to reduce power consumption, the steam consumption, get rid of slag at every turn and can save 4m
3Material, got rid of slag according to per three days and once calculate, produce 18000 tons of production lines per year and can save 480m every year
3Material, 134 tons of volume increase DEXTROSE ANHYDROUSs are for enterprise has retrieved a large amount of economic losses.
