Description
Technical field
The utility model is related to a kind of refined sugar processing unit (plant)s based on activated carbon decolorizing, belong to Sugar Engineering technology neck
Domain.
Background technology
In refined sugar clarifying process, traditional method is to first pass through the pigment that honey washout goes in raw sugar 40%~50%,
Then raw sugar is dissolved, obtains remelt syrup, recycled carbon full charge and filtering or phosphoric acid floats and the method for filtering removes back
The 40%~60% of remaining pigment in dissolved syrup finally further uses ion exchange resin and remelt syrup progress desalination is taken off
Color can obtain the product that purity is about 99.9% after crystallization.But after carbon full charge and filtering or phosphoric acid are floated and are filtered
Remelt syrup turbidity it is still higher, it is easy to pollute the ion exchange resin of postorder workshop section, not only increase ion exchange resin
Load, also reduce service life of ion exchange resin.In order to be lowered into the turbidity of remelt syrup before ion exchange resin, have
Dissolved syrup of whirling after carbon full charge or phosphoric acid float is passed through plate and frame filter press, leaf filter and pocket type by a little sugar refineries successively
Filter three-stage filtration, but effect is still undesirable.In order to be lowered into before ion exchange resin the turbidity of remelt syrup and
Shorten refined sugar clarification process flow, Peng Wenbo et al. (number of patent application：201310729069.3) reported remelt syrup
Successively by plate and frame filter press coarse filtration, microfiltration of ceramic membrane, the decoloration of ion exchange resin desalination is then entered back into；Though this method
Remelt syrup can so be made to obtain relatively low turbidity before entering ion exchange resin, also shorten refined sugar clarification process flow,
But the process due to being washed which omits raw sugar honey and remelt syrup carbon full charge twice are important, along with ceramic micro filter film does not have
The ability of standby decoloration so that the color value of remelt syrup is higher before into ion exchange resin, not only shortens the regeneration of resin
Period and the regeneration frequency for increasing resin also add the load of resin, can also reduce the service life of resin.Therefore it provides
A kind of clarifying effect is more preferable, production efficiency higher, and the lower refined sugar defecation method of cost is necessary.
Utility model content

A kind of refined sugar processing unit (plant) based on activated carbon decolorizing, including sequentially connected raw sugar dissolving case, ceramic membrane group
Part, activated carbon decolourize case, plate and frame filter press, the first exchange resin tower and the second exchange resin tower in advance.
Further, the device, specific connection relation are as follows：
Raw sugar dissolving case juice opening is connect with ceramic film component into juice mouth, and ceramic film component trapped fluid outlet connection is back to
Raw sugar dissolves case, and the ceramic film component juice opening case that decolourizes in advance with activated carbon is connect into juice mouth, activated carbon decolourize in advance case juice opening and
Plate and frame filter press into juice mouth connect, plate and frame filter press juice outlet connect with the first exchange resin tower into juice mouth, first from
Sub-exchange resin tower juice opening is connect with the second exchange resin tower into juice mouth.
Further, raw sugar dissolving case and activated carbon decolourize case with agitating device in advance.
Further, first exchange resin tower is lower charging top discharge.
Further, second exchange resin tower is upper feeding bottom discharge.
Further, the average membrane pore size of the ceramic film component is 0.005~0.5 μm, the ceramic membrane filter
Operating condition be：Transmembrane pressure is 0.10~0.40MPa, and crossflow velocity is 4.0~5.0m/s, and filtration temperature is 80~95
℃。
Further, first ion exchange resin is macroporous strong basic anion exchange resin.
Further, second ion exchange resin is storng-acid cation exchange resin or Subacidity cation
Exchanger resin.
Compared with prior art, the advantageous effect that the utility model has：
1st, it using the remelt syrup after ceramic micro filter film process carbon full charge and plate and frame filter press filtering, reduces into ion
The turbidity of remelt syrup before exchanger resin, so as to reduce the load of ion exchange resin and increase ion exchange resin
Service life；And membrane resistance is smaller caused by fouling on ceramic membrane, thus ceramic membrane cross rate clarification syrup membrane flux it is larger, and film
Flux decline speed is slow, and higher membrane flux can be maintained to filter, so as to extend the Membrane cleaning period and reduce cleaning frequency membrane.
2nd, the multistage microfiltration of ceramic membrane system being made of the ceramic micro filter film of Pyatyi parallel connection is employed, every grade by two film groups
Part forms, and has level-one to play replacement wheel and washes, ensure that microfiltration of ceramic membrane system is capable of the operation of long-time stable.
3rd, remelt syrup enter ion exchange resin depth decoloration before, employ honey wash, carbon full charge twice it is more honest and clean
The process of valency decolourizes in advance to raw sugar and remelt syrup, can not only reduce the load of ion exchange resin, can also increase
Add its service life.
4th, obtained refinery liquor turbidity is less than 1.0NTU, color value is less than 10IU, conductivity is less than 10 μ s/cm, clarification effect
Fruit is preferable.
