Abstract
Description
Technical Field
[0001] The utility model relates to amino acid production, and more specifically, to an exhaust gas emission device for 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. A large amount of exhaust gas is generated during the amino acid production process.
[0005] Existing exhaust gas emission devices include exhaust pipes, air filtration devices (filter meshes), and exhaust fans. The air filtration devices and exhaust fans are both installed on the exhaust pipes. The existing exhaust gas emission devices have the following deficiencies:
[0006] ① Since the exhaust gas contains not only gases but also other impurities such as dust and relatively viscous impurities, these impurities may not be filtered out solely by the air filtration device, or if they can be filtered out, it will cause the air filtration device to quickly lose its filtering function due to blockage.
[0007] ② Even if there are no other impurities such as dust and relatively viscous impurities and it is only ordinary exhaust gas, in order to ensure the filtering effect, a filter mesh with a lower mesh number needs to be used. However, when air flows through a filter mesh with a lower mesh number, the resistance it encounters is greater, which leads to a larger load on the entire system and serious energy consumption. Summary of the Utility Model
[0008] In view of the above problems, the utility model provides an exhaust gas emission device for amino acid production, which aims to improve at least one of the problems mentioned in the background art.

The second purification device includes at least one purification plate evenly distributed with holes. The bottom of each purification plate is detachably connected to the bottom of the lower cavity, and the top is adjacent to the inclined wall of the upper cavity or the inner wall of the cover.
[0010] Optionally, there are more than three purification plates, and the purification plates are arranged equidistantly and parallelly.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without making creative efforts shall fall within the scope of protection of this application.
[0025] The technical solutions of the present utility model will be described in detail below with specific embodiments. These specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.
[0026] Please refer to Figures 1 - 3 , Figure 1 which is a schematic structural diagram of an exhaust gas emission device for amino acid production provided by the present utility model, Figure 2 which is a schematic structural diagram of the first filtration unit provided by the present utility model, Figure 3 which is a schematic structural diagram of the filter plate provided by the present utility model.
[0027] An exhaust gas emission device for amino acid production includes an exhaust pipe 1 and an extraction pipe 2. An extraction fan 4 and a first purification device 9 are installed on the extraction pipe 2. The first purification device 9 is an air filter screen, and the first purification device 9 is located in front of the extraction fan 4. A disposable treatment device 3 is detachably connected between the exhaust pipe 1 and the extraction pipe 2. The other end of the exhaust pipe 1 communicates with the exhaust port of the workshop. The disposable treatment device 3 includes a lower cavity 5 with a square cross-section and an upper cavity 6 with a right-angled trapezoidal cross-section. The lower cavity 5 and the upper cavity 6 are connected to form an installation space 7. The lower cavity 5 communicates with the exhaust pipe 1. The inclined wall of the upper cavity 6 is close to the exhaust pipe 1. The horizontal center line of the lower cavity 5 is above the horizontal center line of the exhaust pipe 1. The bottom of the lower cavity 5 is lower than the outer wall of the exhaust pipe 1. The right-angled end of the upper cavity 6 communicates with the extraction pipe 2. The inner diameter of the extraction pipe 2 = the inner diameter of the exhaust pipe 1. The height of the upper cavity 6 is greater than the inner diameter of the extraction pipe 2. A detachable cover 8 is installed at the top of the upper cavity 6. A second purification device 10 is installed in the installation space 7. The second purification device 10 includes at least one purification plate 11 evenly distributed with holes 12. The bottom of each purification plate 11 is detachably connected to the bottom of the lower cavity 5, and the top is close to the inclined wall of the upper cavity 6 or the inner wall of the cover 8.
[0028] Through the upper chamber 6, the lower chamber 5 and the installed purification plate 11 of the easy-to-handle device 3, when the exhaust gas from the exhaust pipe 1 enters the lower chamber 5, since the height of the purification plate 11 is larger than the inner diameter of the exhaust pipe 1, the exhaust gas impacts the purification plate 11, and the airflow impacting the hole 12 enters the hole 12 and continues to move forward, while the airflow impacting the part of the purification plate 11 without the hole 12 is blocked and cannot continue to move forward but moves upward. At this time, the sticky substance or powder layer either adheres to the purification plate 11 or falls to the bottom of the lower chamber 5. A part of the airflow running upward after preliminary purification goes up to the top of the purification plate 11, and is purified again from the small gap between the purification plate 11 and the inner wall of the inclined wall or the cover 8. When passing through the hole 12, the sticky substance adheres to the hole wall of the hole 12. When the gas coming out of the hole 12 enters the next purification plate 11, it is purified again.
[0029] When there are too many impurities trapped in the disposable device 3, which affects purification, the disposable device 3 can be disassembled and replaced with a new disposable device 3. The disassembled disposable device 3 can be reused after cleaning. Since the aperture 12 is large, it is easy to clean. The air filter installed in the exhaust pipe 2 has a lighter purification responsibility. On the one hand, it can be used for a longer time. On the other hand, a filter with a higher mesh number can be selected while ensuring the same purification effect.
[0030] Those skilled in the art should be aware that the method of detachably connecting the easy-to-handle device 3 to the exhaust pipe 1 and the exhaust pipe 2 is prior art, and those skilled in the art can make the connection according to specific needs and ensure that the exhaust gas does not leak after the connection. For example, but not limited to, the easy-to-handle device 3 can be connected to the exhaust pipe 1 and the exhaust pipe 2 via flanges, and in order to enhance the sealing, an O-ring or the like can be added during the connection.
[0031] Those skilled in the art should know that the detachable connection method of the cover 8 and the purification plate 11 is a prior art. Those skilled in the art can make connections according to specific needs and ensure that the exhaust gas does not leak after the connection. For example, but not limited to, the detachable connection method of the cover 8 and the purification plate 11 can be connected by bolts, studs and the like in fasteners.
[0032] In one or more specific embodiments, in order to obtain a better interception effect, the number of purification plates 11 is more than three, and the purification plates 11 are arranged in parallel and at equal distances.
[0033] In one or more specific embodiments, in order to obtain a better interception effect, the holes 12 of two adjacent purification plates 11 are staggered so that most of the airflow from the holes 12 of the upper purification plate 11 impacts the position without holes 12 of the next purification plate 11 .
[0034] In one or more specific embodiments, to obtain a better retention effect, the diameter of the hole 12 is 1-2 mm, the thickness of the purification plate 11 is 20-40 mm, and the distance between adjacent holes 12 is 3-5 mm.
[0035] In one or more specific embodiments, to obtain a better retention effect, the distance between the purification plates 11 is 0.05 m - 0.1 m.
[0036] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them; 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.
