Problems solved by technology

[0005] The technical problem mainly solved by the present invention is that calcium salt is difficult to remove in beet sugar production, and it is difficult to deal with regeneration waste liquid when decalcification resin is used to remove it. A beet sugar decalcification system enables beet sugar production to save the stage of stopping production and cleaning fouling, and realizes real continuous production

Embodiment 1

[0045] If the location of the pre-carbon filling tank is relatively high and / or far away, a regeneration discharge transfer pump P-DC04 can be installed on the regeneration discharge pipeline, and this pump can be used for relay transportation, which can reduce the pipeline pressure of regeneration discharge damage.

[0046] Rinsing and preheating zone (11--12 process positions): including the resin column switched from the regeneration zone, the number of resin columns is set according to the production situation, and is not limited to 2 in this embodiment. Specifically, cold rinsing is performed at the initial stage of cycle switching, and the softened thin juice cooled to 40°C by the cooling heat exchanger E-DC01 enters from the upper part of 11, is forwardly serially washed to the lower part of 12, and then serially flows to the regeneration area. Rinsing and regeneration are carried out simultaneously, which takes about 0.6 hours. Preheating is performed in the latter st...

Abstract

The invention discloses a beet sugar decalcification system. A production area comprises a plurality of ion exchange resin columns which are arranged in parallel; the cooling backwashing area comprises a failed ion exchange resin column switched from the production area; the regeneration area comprises an ion exchange resin column switched from the cooling backwashing area, and NaOH softening thin juice is used for regenerating resin in the ion exchange resin column subjected to backwashing; the leaching and preheating zone comprises an ion exchange resin column switched from the regeneration zone, and the softening thin juice leaches and preheats resin in the ion exchange resin column. After the softened thin juice obtained through the beet sugar thin juice softening method enters a subsequent evaporator and other procedures, the scaling phenomenon of the evaporator and crystallization sugar boiling equipment is reduced, the situation that production is stopped due to descaling of the evaporator and other equipment is avoided, continuous production of beet sugar is achieved, and labor cost is saved. And meanwhile, the service lives of the evaporator and the crystallization sugar boiling equipment are prolonged.

Description

technical field [0001] The invention relates to the technical field of beet sugar production, in particular to a beet sugar decalcification system. Background technique [0002] The ion exchange method began in the 1940s. It utilizes the unique ion exchange properties of synthetic resins and has a wide range of applications in material purification technology. At the end of the 20th century, all beet sugar producing countries in the world, especially Europe and the United States, have made great progress in ion exchange cleaning sugar juice from research to application, from resin decalcification, desalination, dealkalization to resin decolorization, etc. A lot of successful experiences have been obtained. [0003] The domestic sugar industry applies resin decalcification to sugar production. In recent years, it is mainly the sugar cane sugar enterprises in the south, and the sugar beet sugar enterprises in the north have tried resin decalcification. However, due to the imm...
