Description

Technical Field

[0001] The utility model relates to a decolorization and filtration device, in particular to a decolorization and filtration device for valine production. Background Art

[0002] In the production process of valine, especially when produced by microbial fermentation, a large amount of yellow pigments will be generated in the fermentation broth, and these pigments will affect the color and purity of the product. Through decolorization treatment, these pigments can be effectively removed, and the purity and appearance quality of the product can be improved.

[0003] For pharmaceutical-grade L-valine, the Chinese Pharmacopoeia stipulates that its light transmittance should reach or exceed 99.5%. Therefore, decolorization treatment is an important step to ensure that valine products meet pharmaceutical standards. In the decolorization process of valine, activated carbon is used as an adsorbent for decolorization. Usually, while using activated carbon to remove pigments, some materials will be adsorbed on the activated carbon. If not treated, it will cause adsorption loss of valine and reduce the product yield. Summary of the Utility Model

[0004] In order to overcome the drawback that when using activated carbon to remove pigments in the decolorization process, some materials will be adsorbed on the activated carbon. If not treated, it will cause adsorption loss of valine and reduce the product yield. The purpose is to provide a decolorization and filtration device for valine production that can desorb and recover the materials adsorbed on the activated carbon to ensure the product yield.

[0005] The technical solution is as follows: A decolorization and filtration device for valine production, including a bottom plate, a stock solution tank, a transmission member I, a filtration tank, a liquid extraction pump, a diversion pipe, a decolorization tank, an adsorption cylinder, a steam pipe, a condensation member, and a discharge pipe. The stock solution tank is arranged on the left side of the top of the bottom plate. The lower right side of the stock solution tank is equipped with a transmission member I. The transmission member I consists of a lifting pump and an infusion pipe. The upper part of the infusion pipe of the transmission member I is connected and communicated with the filtration tank. The lower right side of the filtration tank is provided with a diversion pipe. The diversion pipe is a three-way pipe. Liquid extraction pumps are arranged on both of the right two pipelines of the diversion pipe. Two decolorization tanks are symmetrically arranged in the front and back on the right side of the bottom plate. The right two pipelines of the diversion pipe are respectively communicated with the upper left parts of the two decolorization tanks. Adsorption cylinders are arranged inside the decolorization tanks. Discharge pipes are connected and communicated with the lower parts of the decolorization tanks. Steam pipes are connected to the upper left and right sides of the decolorization tanks. Condensation members are arranged on the upper parts of the decolorization tanks. The condensation member consists of a condenser and a liquid outlet pipe connected to the upper part of the condenser. The condenser is communicated with the internal space of the decolorization tank, and the other end of the liquid outlet pipe is communicated with the upper part of the filtration tank.

[0006] Furthermore, it also includes a transmission member II and a clear liquid tank. The clear liquid tank is arranged on the right side of the bottom plate. The left part of the clear liquid tank is connected with a transmission member II. The transmission member II consists of a three-way pipe and an infusion pump. The left two pipelines of the three-way pipe of the transmission member II are respectively connected and communicated with the discharge pipes at the lower parts of the two decolorization tanks.

[0007] Furthermore, it also includes a stirring member and blades. The stirring member is installed at the lower part of the filtration tank.

[0011] The beneficial effects are as follows: By setting a thermal desorption system in the decolorization tank, the valine adsorbed on the activated carbon is desorbed and recycled, reducing the loss caused by the production process during valine production and ensuring the product output.

[0012] By setting an air adding mechanism in the decolorization tank of the present utility model, during decolorization, by injecting gas into the liquid, due to the different media, there is a certain resistance.

[0020] The following describes the present invention in detail with reference to the drawings and specific embodiments, but it is not intended to limit the present invention.

[0021] Embodiment 1: A decolorization and filtration device for valine production, as Figures 1-4 shown, includes a bottom plate 1, a stock solution tank 2, a transmission member 1 3, a filtration tank 4, a liquid extraction pump 41, a diversion pipe 42, a decolorization tank 5, an adsorption cylinder 51, a steam pipe 52, a condensation member 53 and a discharge pipe 54. The bottom plate 1 is made of metal or concrete and is provided with a flat table for installing the device to ensure the stability and firmness of the installed components. On the left side of the top of the bottom plate 1, there is a stock solution tank 2 for storing the undecolorized crystal dissolved stock solution. On the lower right side of the stock solution tank 2, there is a transmission member 1 3 for pumping the stock solution into the filtration component. The transmission member 1 3 is composed of a lifting pump and an infusion pipe connected to the output end of the lifting pump. The input end of the lifting pump of the transmission member 1 3 penetrates into the stock solution tank 2, and the upper part of the infusion pipe of the transmission member 1 3 is connected to a filtration tank 4. The stock solution is transmitted to the filtration tank 4 through the transmission member 1 3. A multi-layer filter membrane is provided in the filtration tank 4, and when the stock solution flows into the filtration tank 4, it will be filtered to achieve the purpose of removing impurities and purification. A mechanism for pumping out the mixed liquid on the filter membrane should be provided on the filtration tank 4 to clean the waste liquid in time;

[0022] Among them, two decolorization tanks 5 are symmetrically arranged before and after on the right side of the bottom plate 1. A tee-shaped diversion pipe 42 is provided on the lower right side of the filtration tank 4, as Figures 1-2As shown in the figure, the two pipelines on the right part of the diversion pipe 42 are respectively connected to the upper left sides of two decolorization tanks 5. A liquid extraction pump 41 for discharging the filtered stock solution into the decolorization tank 5 on the same side is provided on each of the two pipelines on the right part of the diversion pipe 42. An adsorption cylinder 51 filled with activated carbon is provided inside each decolorization tank 5. An air separation layer is arranged inside the adsorption cylinder 51, and the activated carbon is placed in the air separation layer. The outer wall of the adsorption cylinder 51 is provided with a hollow structure, so that the granular activated carbon will not leak out of the adsorption cylinder 51. A discharge pipe 54 for discharging the decolorized liquid is connected and communicated with the lower part of each decolorization tank 5. The discharge pipe 54 is normally closed. Steam pipes 52 are connected to the upper left and right sides of each decolorization tank 5. The two steam pipes 52 on the decolorization tank 5 are respectively a steam inlet pipe and a steam outlet pipe. Steam enters the decolorization tank 5 through one of the steam pipes 52 and exits through the other steam pipe 52. A filter screen for separating and retaining desorbed substances is arranged at the pipe orifice of the steam pipe 52 through which the steam exits, so as to prevent the steam mixed with desorbed substances from being discharged through the steam pipe 52. A condensing member 53 for condensing and recycling the steam of the mixed desorbed raw materials is provided on the upper part of each decolorization tank 5. The condensing member 53 is composed of a condenser and a liquid outlet pipe connected to the upper part of the condenser. The condenser is communicated with the internal space of the decolorization tank 5. The other end of the liquid outlet pipe is communicated with the upper part of the filtration tank 4. The condensate of the desorption treatment is discharged into the filtration tank 4 through the liquid outlet pipe of the condensing member 53. By arranging two decolorization tanks 5, when desorption processing is carried out in one decolorization tank 5, the other decolorization tank 5 is used for decolorization processing, so as to ensure the continuous progress of the decolorization work and ensure the processing efficiency.

[0023] When the solution needs to be decolorized, first, the liquid in the stock solution tank 2 is pumped into the filtration tank 4 through the transfer member 1, and the filtration tank 4 is used for filtration and purification. Subsequently, a liquid extraction pump 41 is started to discharge the liquid in the filtration tank 4 into the decolorization tank 5 connected to the pipeline where the liquid extraction pump 41 is installed. The liquid entering the decolorization tank 4 will contact the adsorption cylinder 51, and the activated carbon inside the adsorption cylinder 51 adsorbs the pigments in the liquid. The pigments and part of valine in the liquid will be adsorbed by the activated carbon. After a period of time, the decolorized liquid is completely discharged from the discharge pipe 54. At this time, high-temperature steam is introduced through one of the steam pipes 52. The steam enters the decolorization tank 5 and contacts the adsorption cylinder 51 to perform thermal desorption on the substances adsorbed on the activated carbon. The desorbed substances are mixed into the steam and enter the condensing member 53 upward. The steam is condensed by the condensing member 53, and the condensate flows back into the filtration tank 4 through the discharge pipe of the condensing member 53. Through the above process, the valine adsorbed on the activated carbon is desorbed and recycled, reducing the loss caused by the production process during valine production and ensuring the product output.

[0024] Example 2: On the basis of Example 1, as Figures 1-2As shown in the figure, it further includes a second transmission member 6 and a clarified liquid tank 7. A clarified liquid tank 7 for storing the decolorized clarified liquid is provided on the right part of the bottom plate 1. The left part of the clarified liquid tank 7 is connected with a second transmission member 6 for transmitting the decolorized liquid into the clarified liquid tank 7. The second transmission member 6 is composed of a three-way pipe and an infusion pump. The two pipelines on the left part of the three-way pipe of the second transmission member 6 are respectively connected and communicated with the discharge pipes 54 at the lower parts of the two decolorizing tanks 5. When the liquid is discharged from the discharge pipe 54, the liquid will flow into the pipe of the second transmission member 6. At this time, the infusion pump of the second transmission member 6 is started to transmit the liquid into the clarified liquid tank 7. The liquid in the decolorizing tank 5 is pumped out in time through the second transmission member 6 to ensure that the decolorizing tank 5 can enter the working state in time for the next batch of decolorization treatment.

[0025] In a specific embodiment: As Figure 1 、 Figure 2 and Figure 5 shown in the figure, it further includes a stirring member 8 and blades 81.

No less than two blades 81 are fixedly provided on the rotating shaft of the stirring member 8. The blades 81 rotate in the filtration tank 4. The setting mode of the blades 81 is: arranged above the multi-layer filter membranes in the filtration tank 4 except for the liquid outlet part at the lowermost part. The blades 81 continuously stir the liquid before filtration. The purpose of setting the stirring member 8 is to uniformly mix the liquid recycled in the condensing member 53 and the liquid injected from the raw material tank 2, avoid liquid stratification in the filtration tank 4 caused by liquids from different sources and with different components, improve the consistency before the subsequent raw liquid is decolorized, and ensure the stability during decolorization.

Through the filtering member 9 arranged at the discharge pipe, when the liquid is discharged from the decolorizing tank 5, the mixed liquid with activated carbon is subjected to microporous filtration to reduce impurity mixing, and a slag discharge assembly should be provided on the filtering member 9 to timely discharge the blocked waste activated carbon to ensure the normal progress of the filtering work.

[0027] In a specific embodiment: As shown in Figures 1-3, it includes an air inlet pipe 10. The upper parts of the decolorizing tanks 5 are respectively connected and communicated with an air inlet pipe 10 connected to an external air source. When discharging the liquid in the decolorizing tank 5, by connecting an external air source into the air inlet pipe 10, the tank is pressurized to accelerate the discharge of the liquid in the decolorizing tank 5 and reduce the discharge time.

[0028] In a specific embodiment: As shown in FIGS. 1-3, it further includes a gas inlet pipe 11. The lower part of the decolorization tank 5 is provided with a gas inlet pipe 11. The gas inlet pipe 11 is composed of an annular pipe with a number of air outlet holes arranged in the filter cartridge and an air inlet connector passing through the decolorization tank 5.
