Abstract
The invention provides a device for filtering decoloration materials for use in the production of anhydrous glucose, which comprises a plate-frame shape filtering machine, a flat filtering machine as well as a micron filter, wherein the plate-frame shape filtering machine and the flat filtering machine are connected parallelly and then the micron filter is connected with the plate-frame shape filtering machine and the flat filtering machine in series; a feeding/discharging pipe of each filtering equipment is provided with a valve; and the flat filtering machine is connected with a decoloration tank through a discharging pipe with a valve. With the combined filtering device, the filtering process can be performed continuously, thereby avoiding shutdown caused by cleaning the blockage in the filtering machine, reducing the loss of glucose liquid during cleaning and maintenance and facilitating the operation of slag throwing.
Description
Technical field
The present invention relates to the production of dextrose anhydrous, be specifically related to the filtration unit behind the decoloration process in the anhydrous dextrose production process.
Background technology
In the production process of dextrose anhydrous, material can have certain color and mix the impurity that other are arranged because of steps such as saccharification, in order to guarantee the quality of final dextrose anhydrous, need decolour to material, the technical process of decolouring is: add gac according to a certain percentage in material, adsorpting pigment and other impurity.After gac stirs in material, squeeze in the filter, form filter cake, after the material after filtering reaches processing requirement, send into next step operation with pump.
General employing plate and frame filter in the existing technology carries out filtering separation to decolorization material, and another platen frame filter of connecting on the pipeline before filtrate enters storage tank is in the hope of improving filter effect.But since plate and frame filter filtration capacity a little less than, and inside is stopped up by filter residue through regular meeting, need often get rid of slag operation, particularly enter the plate and frame filter that is provided with before the storage tank in case stop up, just must stop feed and carry out maintenance of clean-up, be unfavorable for carrying out continuously of whole technology, for the continuous operation that guarantees equipment just must be provided with a surge tank before this filter, material when making maintenance can flow into and be unlikely to waste in the jar, has so just increased the complicacy of technology and the cost of equipment again; Simultaneously owing to except that containing gac and impurity, also contain a large amount of Glucose Liquids in the filter, when cleaning, can't in time recycle, thereby reduced the ultimate yield of producing, cause bigger loss to enterprise, if liquid glucose is sneaked in the gac and discharged, can cause the viscosity of its mixture to increase greatly, the mobile reduction, easier occluding device and pipeline are maintenance and cleaning increase difficulty.
Summary of the invention
At the deficiency that prior art exists, the invention provides the combined filtering device of a kind of charcoal absorption decolouring back material, this filtration unit comprises that plate and frame filter in parallel and flat panel filter machine and placed in-line with it thereafter micron filter combine.Use this combined filtering device, can realize the continuous operation of filtration procedure, avoid causing shut-down, reduced the loss of glucose when cleaning maintenance simultaneously, made things convenient for and got rid of slag operation because of filter stops up cleaning.
Filtration unit of the present invention is in parallel by at least one platen frame filter and at least one flat panel filter machine and forms, and is in series with micron filter on the pipeline before the filtrate tanks opening for feed; All be provided with valve on the feed and exhaust tube of every filter; The flat panel filter machine is connected with bleacher by the drainage conduit that has valve.
Because the performance characteristics and the working order of plate and frame filter and dull and stereotyped filter are different, and all be provided with valve on the feed and exhaust tube of every filter, like this when need overhaul cleaning to filter the time, only need close the valve on this filter feed and exhaust tube, filter and production line are broken away from enter standby inspecting state, can not cause stopping production, keep the continuous operation of production process because of the fault or the obstruction of filter.When the needs faster production, filter in parallel can standard-sized sheet, has increased throughput when guaranteeing filter effect; Be provided with the drainage conduit that has valve on the flat panel filter machine, by drainage conduit the flat panel filter machine is connected with bleacher, drainage conduit valve closes during works better, when the flat panel filter machine gets rid of slag operation or maintenance, open the drainage conduit valve, remaining liquid glucose in the filter can directly flow back in the bleacher, reduced carbon slurry amount, diatomaceous consumption when having reduced the rear portion to the filtration of carbon slurry, having reclaimed a large amount of liquid glucoses simultaneously gets back in the manufacturing procedure, also reduced the treatment process of rear portion for enterprise has retrieved loss, reduced cost liquid glucose;
The micron filter of having connected on the pipeline of filtration unit of the present invention before the filtrate tanks opening for feed, selection series connection micron filter why, be because most gacs are filtered out by the filter of front parallel connection in the material, it is little to filter load herein, only need improve filter effect, the performance characteristics of micron filter just is applicable to this demand; Because what adopt in the micron filter is filter bag, filtering effect is greater than flame filter press, after reaching processing requirement, the filter residue in the filter bag can change filter bag easily, needn't dismantle whole filter, reduce working strength of workers and saved the time, do not influenced the continuity of whole process of production simultaneously.
By adopting this filtration unit, carbon slurry amount has reduced 2/5ths when making whole filtration unit get rid of slag operation, and it is few to contain glucose amount in the filter residue, the hammer degree descends 2 times, viscosity also reduces greatly, and anhydrous like this carbon slurry also is not easy the plugging road, has made things convenient for the processing in later stage.Adopt this device back to reduce power consumption, the steam consumption, get rid of slag virtually at every turn and saved 2m
3Material, got rid of slag according to per three days and once calculate, can save 250m every year
3Material is produced dextrose anhydrous 90-100 ton more, for enterprise has retrieved a large amount of financial losses.
Overhaul and the process of scarfing cinder in, saved a large amount of time, need half an hour when originally the plate and frame filter before the storage tank being cleared up, after now adopting micron filter to filter, only need 5 minutes replacing filter bags to get final product, the filtration velocity that so only needs to adjust anterior filter just can guarantee that material can not leak outside, and has so just saved surge tank and has reduced processing step, has also saved cost for enterprise simultaneously; And when the filter to parallel connection overhauls, can not influence existing production schedule by the platform maintenance; Former filtration unit just need be changed or be carried out large repairs in general 4 years simultaneously, and device of the present invention can reach more than 8 years in non-stop run, has prolonged the working life of each filter, for enterprise has saved a large amount of funds; This device promptly can be as the filter plant of the first time in the anhydrous dextrose production process behind the decoloration process, also can be used as the filter plant behind the decoloration process for the second time.
