Problems solved by technology

[0004] But the disadvantage is that the price of the resin is high, the investment of the resin and the equipment used is large, and the performance of the resin needs to be periodically regenerated to maintain the performance of the resin; if the processed material contains more impurities, the life of the resin will be shortened and the increase in regeneration cost

Embodiment 1

[0061] This embodiment provides a refined sugar decolorization treatment device, including an operating system, a regeneration system and an anti-regeneration system.

[0062] Such as figure 1 As shown, the operating system includes a syrup pump, a decolorized sugar solution pump 6, an ion exchange bed group, a dilute sugar solution tank 5, a concentrated sugar solution tank 4 and a decolorized sugar solution tank 3, wherein the ion exchange bed group is provided with three ion exchange Bed 2, the inner cavity of each ion exchange bed 2 is divided into an upper chamber and a lower chamber, the upper chamber is filled with acrylic resin and the lower chamber is filled with styrene resin. The three ion exchange beds 2 are sequentially connected to the decolorization program. Compared with a single ion exchange bed 2, the three ion exchange beds 2 can improve the decolorization capacity. The upper port and the lower port of each ion exchange bed 2 are provided with inlet and out...

Embodiment 2

[0069] This embodiment provides a decolorization treatment process, based on a refined sugar decolorization treatment device in Example 1, comprising the following steps:

[0070] S1: Add sugar,

[0071] S11: Pump sweet water from the lower port of each ion exchange bed through a syrup pump to soak the resin inside the ion exchange bed;

[0072] S12: The dilute sugar solution pump draws the dilute sugar solution from the dilute sugar solution tank and pumps it in from the lower port of each ion exchange bed. The upper port of each ion exchange bed is returned to the dilute sugar solution tank;

[0073] S13: The concentrated sugar solution pump draws the concentrated sugar solution from the concentrated sugar solution tank and pumps it in from the lower port of each ion exchange bed. The upper port of each ion exchange bed is returned to the concentrated sugar solution tank, and the sugar feeding is completed;

[0074] S2: decolorization run,

[0075] S21: In S13, when the ...

Embodiment 3

[0085] This embodiment provides a backwash treatment process, based on the refined sugar decolorization treatment device of Example 1, the resin in the ion exchange bed is blocked by suspended matter and affects the passing of the sugar solution, then the following steps are performed:

[0086] S1: The external salt solution pipeline leads to the desalted salt water tank, and the desalted water is pumped in from the lower port of each ion exchange bed through the salt solution pump and bag filter. The flow rate is 1~2BV / h. The input time is 1 hour, and the eluate is discharged from the waste liquid pipe;

[0087] S2: The external desalinated water pipeline pumps desalted water at 70-80°C into the desalted water tank and the heat preservation water tank, and then pumps it in from the upper port of each ion exchange bed through the regeneration pump. After 1 hour, the eluate is discharged from the waste pipe, and the backwashing is completed.

Abstract

The invention discloses a refined sugar decolorization treatment device and a decolorization, backwashing, regeneration and cleaning process. An operation system comprises a syrup pump, a decolorization sugar liquid pump, an ion exchange bed group, a dilute sugar liquid tank, a concentrated sugar liquid tank and a decolorized sugar liquid tank. A regeneration system and a reverse regeneration system are communicated with a first pipeline and a second pipeline through pneumatic ball valves and are used for regenerating the ion exchange bed group. The regeneration system comprises a heat exchanger, a heat preservation water tank, a regeneration water pump, a salt dissolving tank, a salt liquid pump, a bag type filter, a desalted water tank, an alkali discharging pump, an alkali storage tank,an alkali metering tank and an alkali metering pump. The reverse regeneration system comprises an ejector, an acid metering box, an acid storage tank and an acid discharging pump which are sequentially communicated. The device has the advantages of small occupied area, no need of external cleaning equipment, good treatment effect, stable removal rate and the like.

Description

technical field [0001] The invention relates to the field of sugar decolorization treatment, in particular to a refined sugar decolorization treatment device and processes for decolorization, backwashing, regeneration and cleaning, and is especially widely used in the fields of refined sugar and high-grade edible syrup. Background technique [0002] With the improvement of people's living standards, people's quality requirements for sugar are gradually increasing, and the market demand for refined sugar, which belongs to high-end sugar products, is also increasing. In order to meet market demand, in recent years, my country has built a lot of Refining sugar factory. Appropriate refined sugar production process can realize the production of refined sugar products that meet market requirements at the most economical investment cost. Traditional farmland white sugar usually does not need to use decolorization process from the perspective of production investment or product requ...
