Description

Technical Field

[0001] The utility model relates to amino acid production, and more specifically, to a decolorization device for intermediate liquid products in amino acid production. Background Art

[0002] Amino acids are a class of amphoteric organic compounds containing basic amino groups and acidic carboxyl groups, and are the basic building blocks of biologically functional macromolecular proteins.

[0003] Amino acids have a very wide range of uses, including but not limited to the fields of food industry, medicine, feed industry, chemical industry, agriculture, and cosmetics.

[0004] There are various amino acid production processes, mainly divided into two types: chemical synthesis and microbial fermentation. The intermediate liquid products formed during the amino acid production process carry pigments for various reasons. If these pigments are not removed, they will seriously affect the quality of the final product. Therefore, the decolorization step is an important process in amino acid production.

[0005] In the prior art, when the decolorization adsorption filtration device filters, the intermediate liquid product enters the cavity from the feed port and then reaches the surface of the decolorization adsorption filtration layer. The intermediate liquid product penetrates and contacts with the decolorization adsorbent, so as to achieve the purpose of decolorization and impurity removal. Since the intermediate liquid product directly falls from the feed port to the decolorization adsorption filtration layer, only a part of the distribution area of the intermediate liquid product in the activated carbon layer is available, and the decolorization adsorbent cannot be fully utilized, which affects the efficiency and effect of the entire decolorization.

[0028] The technical solutions of the present utility model will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0029] Please refer to Figures 1 - 5 , Figure 1 which is a schematic structural diagram of an intermediate liquid product decolorization device for amino acid production provided by the present utility model, Figure 2 which is a schematic structural diagram of an efficiency-enhancing feeding unit provided by the present utility model, Figure 3 which is a schematic top view of a tank cover provided by the present utility model, Figure 4 which is a connection schematic diagram of a connecting pipe, a distribution pipe and a feeding pipe provided by the present utility model, Figure 5 which is a schematic structural diagram of a decolorization filter layer provided by the present utility model.

[0030] An intermediate liquid product decolorization device for amino acid production, comprising a tank cover 2, a tank wall 3 and a tank bottom 4. The tank cover 2, the tank wall 3 and the tank bottom 4 enclose a cavity 1. A decolorized liquid discharge port 6 is provided on the tank bottom 4. A decolorization filter layer 8 is arranged in the cavity 1. The decolorization filter layer 8 is filled with a decolorization filter agent. The decolorization filter layer 8 divides the cavity 1 into an upper cavity and a lower cavity. At least one efficiency-enhancing feeding unit 5 is arranged in the upper cavity. Each efficiency-enhancing feeding unit 5 penetrates through the tank cover 2. Through holes 7 equal in number to the efficiency-enhancing feeding units 5 are provided on the tank cover 2. Each efficiency-enhancing feeding unit 5 includes one first-layer pipe 51, 2 second-layer pipes 54... 2 n-1 ... 2 nth-layer pipes. The middle position of the first-layer pipe 51 is communicated with an upper pipe 52, and both ends are respectively communicated with a first lower pipe 53. The upper end of the upper pipe 52 penetrates through a through hole 7 and is connected to a connecting pipe 9. Each first lower pipe 53 is connected to the middle position of a second-layer pipe 54. Both ends of each second-layer pipe 54 are respectively communicated with a second lower pipe 55,... Each (n - 1)th lower pipe is connected to the middle position of an nth-layer pipe. Both ends of each nth-layer pipe are respectively communicated with an nth lower pipe. The liquid outlet of the nth lower pipe is close to the decolorization filter layer 8, and n is a natural number.

[0031] Through the setting of the efficiency-enhancing feeding unit 5, the intermediate liquid product coming from the connecting pipe 9 outside the decolorization device enters the upper pipe 52 and is then split by the first-layer pipe 51, and then is split into two successively, and at the same time the distribution area is increased. Therefore, when reaching the decolorization filter layer 8, the liquid outlets of the nth lower pipes are distributed at adjacent positions above the entire decolorization filter layer 8. Therefore, the intermediate liquid product enters from the entire cross-section of the decolorization filter layer 8, fully penetrates and contacts with the decolorization adsorbent, making use of the entire decolorization adsorbent, thereby improving the decolorization effect.

[0032] In one or more specific embodiments, n = 6, and better effects can be obtained.

[0033] In one or more specific embodiments, the decolorization filter agent is activated carbon.

[0034] In one or more specific embodiments, in order to obtain a better distribution effect, the upper cavity is square, which is convenient for installing the efficiency-enhancing feeding unit 5.

[0035] In one or more specific embodiments, in order to obtain a better distribution effect, the through holes 7 are arranged along the center line of the tank cover 2 to form a symmetric structure.

[0036] In one or more specific embodiments, the other ends of the connecting pipes 9 are all connected to a distribution pipe 10, and the middle part of the distribution pipe 10 is connected to a feeding pipe 11.

[0037] In one or more specific embodiments, in order to obtain a better decolorization effect, the decolorization device for the intermediate liquid product in amino acid production further includes a partition plate 81, which is connected to the tank wall. The partition plate 81 is evenly distributed with upper holes, and the number of upper holes is the same as the number of the nth lower pipes. The liquid outlet of the nth lower pipe is located below the partition plate 81. Through the arrangement of the partition plate 81, a liquid layer of the same height is formed between the partition plate 81 and the decolorization filter layer 8, further ensuring that the liquid to be decolorized enters from the entire cross-section of the decolorization filter layer 8 and improving the decolorization effect.

[0038] In one or more specific embodiments, in order to obtain a better decolorization effect, the decolorization filter layer 8 includes an upper microporous plate 82 and a lower microporous plate 83. The upper microporous plate 82 and the lower microporous plate 83 wrap the decolorizing agent inside, and the pore diameter of the upper microporous plate 82 > the pore diameter of the lower microporous plate 83. At this time, because the pore diameter of the upper microporous plate 82 > the pore diameter of the lower microporous plate 83, under the same conditions, it is easier for the intermediate liquid product to enter the decolorization filter layer 8 than to leave the decolorization filter layer 8. Thus, the residence time of the intermediate liquid product can be extended, and the decolorization time can be increased, improving the decolorization effect.

[0039] In one or more specific embodiments, when the pore diameter of the upper microporous plate 82 is 1.1 - 1.2 times the pore diameter of the lower microporous plate 83, a better overall effect can be obtained. If it is too small, the decolorization effect will decrease; if it is too large, the liquid accumulation phenomenon will be serious, resulting in difficult liquid discharge.

[0040] Those skilled in the art should know that the maximum pore diameter of the lower microporous plate 83 is smaller than the maximum particle diameter of the decolorizing agent.

[0041] In one or more specific embodiments, the decolorization device for the intermediate liquid product in amino acid production is further provided with support legs 14, which are connected to the tank bottom 4 and used to support the entire device.

[0042] In one or more specific embodiments, the tank bottom 5 can be a flat bottom or a conical bottom, and those skilled in the art can choose according to needs.

[0043] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
