Description
Technical field
The utility model belongs to technical field of functional sugar production, is specifically related to a kind of xylose hydrolysis fluid decoloring equipment.
Technical background
Wood sugar is a kind of pentose, extensively is present in the semicellulose of plant with the form of xylan.Its main application also is applied to the sweetening agent of empty calory mainly as medicine intermediate.At present xylose production mainly with corn cob, Cortex Betulae Luminiferae, stalk etc. be raw material through hydrolysis, decolouring, make with extra care, evaporation, crystallization prepare crystal wood sugar and xylose mother liquid.Existing decolouring device is the device that once decolours, and decolouring back feed liquid printing opacity value is 65%～70%, 80 ℃～90 ℃ of temperature.The shortcoming of this device is:
One, the gac utilization ratio is low, causes hydrolyzate decolorizing not thorough, and residual have partial impurities and a coloring matter, influences follow-up desalination operation, increased the load of ion exchange resin, produces more sewage discharge; Increased production cost simultaneously.
Two, can not reduce the hydrolyzed solution temperature effectively, too high temperature has reduced ion exchange resin work-ing life.
Summary of the invention
The purpose of the utility model provides a kind of xylose hydrolysis fluid decolouring system and device, increases with the load that solves prior art ion exchange resin, and ion exchange resin is short work-ing life, and the consumption of supplementary material is high, finally causes problems such as the production cost of wood sugar is higher.
The utility model mainly is made up of plate filter, decolouring still, sheet frame fresh feed pump, sheet frame discharging pump; Solving the technical scheme that its technical problem adopts is to change to the decolouring device three times by original once decolouring device; The decolouring device specifically is made up of plate filter, decolouring still, sheet frame fresh feed pump, sheet frame discharging pump and pipe connection; Adopt pipe connection to form one group of decolouring unit between the decolouring still of this device, sheet frame discharging pump and the plate filter; The layering of this decolouring device is provided with, and connects successively through pipeline between three decolouring unit, and each decolouring unit is made up of decolouring still, plate filter, sheet frame fresh feed pump, sheet frame discharging pump; Through pipe connection series connection, constitute whole decolouring device, the feed liquid that three decolouring unit come out is three and takes off liquid, gets into the destainer storage tank.
Said decolouring device divides storey setting decolouring unit, and the unit that once decolours is placed on Stall, and the secondary decolourization unit is placed on second floor, and three times the decolouring unit is placed on the 3rd buildings.
Add new charcoal in said three decolouring unit decolouring stills, the useless charcoal that plate filter 3 leaches joins the decolouring still 1 of secondary decolourization unit II; Secondary decolourization unit plate filter 3 leaches to such an extent that useless charcoal joins in the unitary decolouring still 1 that once decolours; Xylose hydrolysis fluid through decolorization filtering, gets into the secondary decolourization unit by the unit that once decolours, and through decolorization filtering, gets into the decolouring unit again three times, behind three decolouring unit, obtains qualified Decoloration of Xylose liquid, gets into the destainer storage tank.
The beneficial effect of the utility model is: make full use of the once useless carbon decoloring surplus in decolouring back, the printing opacity value 83%～90% after the decolouring has improved 20%; Temperature drops to 40 ℃～55 ℃.The minimizing of impurity and coloring matter content to reducing the ion exchange resin load, improves the resins exchange amount, and it is remarkable to reduce the quantity of wastewater effluent effect; Ion exchange resin has been avoided in the reduction of temperature because the infringement that high temperature brings has prolonged work-ing life; Make full use of the decolouring surplus of useless charcoal, improved printing opacity, constant with the charcoal amount, practiced thrift production cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
1 decolouring still among the figure, 2 sheet frame fresh feed pumps, 3 plate filters, 4 sheet frame discharging pumps, 5 destainer storage tanks, 6 pipelines, 7 useless charcoals outlets, 8 hydrolyzed solution imports, 9 gacs inlet, 10 unit that once decolour, 11 secondary decolourization unit, 12 3 decolouring unit.
Embodiment:
The practical implementation process of the utility model is as shown in the figure:
1. the utility model is in series through pipeline by the identical decolouring unit of 3 set constructors, and complete assembly need be placed in 3 floors, and the unit 10 that once decolours is placed in one deck, and secondary decolourization unit 11 is placed in two layers, and three times decolouring unit 12 is placed in three layers.
2. each decolouring unit is made up of decolouring still 1, plate filter 3, sheet frame fresh feed pump 2, sheet frame discharging pump 4.Like the decolouring still 1 in three decolouring unit III, sheet frame fresh feed pump 2, plate filter 3, sheet frame discharging pump 4 links to each other through pipeline successively.
3. connect successively through pipeline between three decolouring unit; Plate filter 3 as in three decolouring unit 12 links to each other with the decolouring still 1 of secondary decolourization unit 11 through pipeline 6, and three times decolouring unit 12 interior decolouring stills 1 link to each other with the sheet frame discharging pump 4 of secondary decolourization unit 11 through pipeline 6.
During this utility model work, at first hydrolyzed solution gets into the unit 10 that once decolours through hydrolyzed solution import 8, via decolouring still 1; Sheet frame fresh feed pump 2, plate filter 3, sheet frame discharging pump 4; Arrive secondary decolourization unit 11; The same manner gets into decolouring unit 12 three times, obtains destainer at last through three decolourings, is stored in destainer storage tank 5.
Gac gets into three decolourings of decolouring still unit 12 through gac import 9 simultaneously; Via decolouring still 1; Sheet frame fresh feed pump 2, Plate Filtration 3 devices, pipeline 6 (falling by deadweight) gets into secondary decolourization unit 11; The same manner gets into the unit 10 that once decolours, and is discharged by useless charcoal outlet 7 at last through three decolourings.Hydrolyzed solution flows to into relative adverse current with gac, and fully impurity is adsorbed in contact, but the gac addition is constant.
With YO more than 2000 tons the wood sugar workshop be example, after hydrolyzed solution was handled via three decolourings, the more former decolouring device of printing opacity was compared and is improved 20%, temperature is reduced to below 55 ℃.And gac reuses 3 times, reaches best decolorizing effect.According to cost statistics: can practice thrift 700 tons of liquid caustic soda every year, 26 tons of hydrochloric acid, 30 tons in water; Through three decolouring posthydrolysis liquid index printing opacity values 83%～90%, 40 ℃～55 ℃ of temperature are beneficial to the control indexes of subsequent handling.
The principle of the utility model is: through increasing the decolouring storage tank, make hydrolyzed solution and gac through 3 adsorption processes, reach high printing opacity, low temperature, purpose that impurity is few.Hydrolyzed solution is successively via one taking off, two take off, three taking off device; Gac is then successively via three taking off, two take off, one taking off device.
