Abstract

The utility model relates to a resin regeneration impurity removing device during xylose production, which belongs to the technical field of functional sugar production. The regeneration impurity removing device adopts the technical scheme that a filtering impurity removing device is additionally added before regenerated liquid enters an ion exchange column; a regenerated liquid tank is arranged at the foremost part of the regeneration system and then connected with a regenerative pump; a T-shaped filter is arranged on a regenerative pipeline between the regenerative pump and the ion exchange column; a filter core is arranged in the T-shaped filter; and a pressure meter is also arranged at the upper part of the T-shaped filter. By installing the T-shaped filter, the regenerated liquid is filtered through the filter and then fed into the ion exchange column, foreign material in the regenerated liquid can be effectively blocked, the regenerated liquid is prevented from being polluted by resin during the regeneration process, the blocking and breaking of the aperture of resin particulate are reduced, and the complete exchange and the normal use of resin are guaranteed, therefore, the device has the advantages of simple structure and safe and reliable operation.

Description

Resin regeneration impurity removed system in the xylose production

Technical field

The utility model belongs to technical field of functional sugar production, relates to regeneration of resin system equipment in the xylose production.

Background technology

At present, in the xylose production process, contain a large amount of pigments in the xylose hydrolysis fluid, impurity such as colloid, its removal method is to adopt decolouring one ion-exchange process, wherein, ion-exchange is to adopt resins exchange, when ion-exchange, when resin surpasses its load, resin promptly lost efficacy, and needed regeneration, industrial, regeneration of ion-exchange resin generally is to adopt certain density acid ﹠ alkali liquid, sometimes, commercial acid alkali lye because in transportation or because the storage time is long and pipe conveying procedure in can introduce impurity such as a certain amount of suspension, but in existing regenerative system equipment, do not have filter impurity can be removed before entering ion exchange column, the acid ﹠ alkali liquid that contains suspension directly enters ion exchange column and contacts with resin, and suspension is wrapped in around the resin material, stopped up the aperture of resin, have a strong impact on the exchange capacity of resin, shortened the service life of resin, thereby influenced the purification and the purification of wood sugar liquid.

Summary of the invention

The purpose of this utility model is to provide a kind of xylose production resin regeneration impurity removed system that is used for, adopt acid ﹠ alkali liquid to carry out regeneration of ion-exchange resin to solve prior art, the acid ﹠ alkali liquid suspension is wrapped in around the resin material, stopped up the aperture of resin, had a strong impact on the exchange capacity of resin, shorten the service life of resin, thereby influenced problems such as the purification of wood sugar liquid and purification.

The technical scheme that its technical problem that solves the utility model adopts is to add the filtering and impurity removing device before regenerated liquid enters ion exchange column.The foremost of this regenerative system is provided with the regeneration flow container, and the regenerated liquid tank is corrosion resistant charcoal steel construction, is connected with regenerative pump; On the regeneration pipeline between regenerative pump and the ion exchange column, the T type filter is set newly, in the T type filter filter core is set, filter core is that network structure, its filtering accuracy are the 10-200 order, this filter core can freely take out, it is convenient to change, a Pressure gauge is also installed on top at the T type filter, falls so that detect the ducted pressure of regeneration at any time.

Adopting good effect of the present utility model is by the new T of installation type filter on the regeneration pipeline between regenerative pump and the ion exchange column, regenerated liquid is admitted to ion exchange column after filtering by filter, can effectively stop the foreign matter in the regenerated liquid, avoid in the regenerative process resin contaminated, reduce the obstruction and the fragmentation of a resin blanking aperture, guarantee the exchange fully and normal use of resin, have simple in structurely, manipulate safe and reliable advantage.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified:

Accompanying drawing 1 is the utility model structural representation,

Accompanying drawing 2 is the utility model T type filter structural representation;

Among Fig. 1: 1 soda acid valve, 2 pure water valves, 3 compressed air valves, 4 regenerated liquid valves, 5 flanges, 6 regenerative pumps, 7T type filter, 8 filter cores, 9 Pressure gauges, 10 ion exchange columns, 11 regeneration flow containers.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

As shown in Figure 1: the resin regeneration knot screen mainly comprises regeneration flow container 11, regenerative pump 6, T type filter 7, ion exchange column 10 in the xylose production; This regeneration impurity removed system is to add the filtering and impurity removing device before regenerated liquid enters ion exchange column 10.The foremost of this regenerative system is provided with regeneration flow container 11, and regeneration flow container 11 tank bodies are corrosion resistant charcoal steel construction, are connected with regenerative pump 6; The new T type filter 7 of installing on the regeneration pipeline between regenerative pump 6 and the ion exchange column 10, employing 316 stainless steels of T type filter 7, filter core 8 is set in the T type filter 7, filter core 8 is netted, corrosion resistant 316 stainless steels, its filtering accuracy is the 10-200 order, and this filter core can freely take out, and it is convenient to change, top at T type filter 7 is provided with Pressure gauge, falls so that detect the ducted pressure of regeneration at any time.

During work, according to the model of ion exchange resin and required regenerated liquid concentration squeezes into a certain amount of acid (alkali) liquid by sour (alkali) valve 1 in regeneration flow container 11 and pure water valve 2 is squeezed into a certain amount of pure water, open compressed air valve 3 feeding compressed air and carry out the mixing of regenerated liquid, regenerated liquid after mixing is opened valve 4 and is entered filtration system 7 by regenerative pump 6, this filtration system is a T type filter, the core component of filter is a filter chipware 8, after entering the filter core that is equipped with the certain specification filter screen when regenerated liquid, its impurity is blocked, the regenerated liquid of cleaning is then discharged by filter outlet, is driven into 10 pairs of resins of sun (the moon) ion exchange column and regenerates.After filter work a period of time, precipitated certain impurity in the cartridge, at this moment increase falls in pressure, and flow velocity can descend, and needs in time to remove the impurity in the cartridge.When needs clean, as long as dismountable filter core is taken out, remove the impurity that leaches after, reload and get final product, therefore, working service is very convenient.The utility model can effectively stop the foreign matter in the regenerated liquid, avoids in the regenerative process resin contaminated, guarantees the normal use of resin, and it is simple and reliable for structure.
