Description

Technical Field

[0001] The present invention relates to the technical field of glycine production equipment, and in particular to a waste gas treatment device for glycine production. Background Art

[0002] Glycine, also known as aminoacetic acid, is a non-essential amino acid. Glycine is a constituent amino acid of the endogenous antioxidant reduced glutathione. It is often supplemented exogenously when the body is under severe stress. It is sometimes called a semi-essential amino acid. Solid glycine is a white to off-white crystalline powder, odorless and non-toxic. It is easily soluble in water and almost insoluble in ethanol or ether. It is used in the pharmaceutical industry, biochemical experiments and organic synthesis. It is the amino acid with the simplest structure in the amino acid series and is non-essential to the human body. It has both acidic and basic functional groups in the molecule, can be ionized in water, and has strong hydrophilicity, but is a non-polar amino acid. It is soluble in polar solvents but difficult to dissolve in non-polar solvents. It also has a high boiling point and melting point. Glycine can be made to present different molecular forms by adjusting the acidity and alkalinity of the aqueous solution.

The present invention allows the glycine production waste gas treated by the wet scrubber to enter the interior of the cooling pipe through the air inlet end of the cooling pipe, removes the internal cooling water, and then passes the gas through the interior of multiple adsorption mechanisms in sequence, so that the activated carbon inside adsorbs ammonia and formaldehyde in the gas, and then removes the adsorption mechanism for absorbing saturated ammonia and formaldehyde, and puts it into a sodium cyanide solution, so that the adsorbed ammonia and formaldehyde are reused in glycine production, and the activated carbon can be regenerated and reused, the process is simple and the cost of reusing ammonia and formaldehyde in the waste gas is greatly reduced.

[0016] 2. When the temperature and humidity are too high, the adsorption capacity of the existing activated carbon will be greatly reduced when it adsorbs gas. In the present invention, cooling water will enter the cooling chamber and the condensation chamber, and finally be discharged from the upper through hole.

In addition, the cooling water inside the cooling chamber will cool down the adsorption shell and the activated carbon, thereby increasing the adsorption capacity of the activated carbon.

[0017] 3. After the activated carbon is saturated with adsorption, the exhaust gas is first stopped, and then the electromagnet is energized in the reverse direction to generate a magnetic field, and at the same time, a repulsive force is generated on the permanent magnet and the permanent magnet block, so that the sliding plate seals the opening of the adsorption shell, and the permanent magnet block drives the sliding head to move upward. Then the rotating frame rotates counterclockwise by 90 degrees, and the adsorption mechanism originally at the rear of the middle part is rotated to the far left, and the adsorption mechanism at the front of the middle part is rotated to the far right. During the process, the sealing mechanism seals the left end of the connecting pipe 1 and both ends of the connecting pipe 2 and the connecting pipe 3, so that the exhaust gas will not leak while the adsorption mechanism is quickly replaced.

The condensation chamber 7 and the liquid inlet chamber 9 are both well sealed with the connecting plate 10, the upper end of the cooling chamber 6 is connected to the condensation chamber 7, and the lower end of the cooling chamber 6 is connected to the liquid inlet chamber 9. The sliding plate 56 is adapted to the opening of the adsorption shell 51, and the two adsorption shells 51 are both connected to the support feet of the rotating frame 4. The adsorption shell 51 is movably installed, and an arc-shaped slide groove is provided on the surface of the adsorption shell 51. The rotating plate 81 is rotatably connected to the inner wall of the condensation chamber 7. The cooling pipe 83 is fixedly connected to the upper connecting plate 10. The drain pipe 84 is provided on the rotating frame 4 to connect the condensation chamber 7 with the liquid inlet chamber 9. The sliding head 131 is adapted to the inner side of the mounting hole 12, the sealing block 136 is adapted to the inside of the mounting hole 12, and the telescopic spring 137 is fixedly connected to the inner wall of the mounting hole 12. Its function is that after the activated carbon 58 is saturated with adsorption, the exhaust gas is first suspended, and then the electromagnet 57 is reversely energized to generate a magnetic field, and at the same time At the same time, a repulsive force is generated on the permanent magnet 54 and the permanent magnet block 134, so that the sliding plate 56 seals the opening of the adsorption shell 51, and the permanent magnet block 134 will drive the sliding head 131 to move upward, and then the rotating frame 4 rotates counterclockwise by ninety degrees, and the adsorption mechanism 5 originally at the rear of the middle part is rotated to the far left, and the adsorption mechanism 5 at the front of the middle part will be rotated to the far right. During the process, since the sealing mechanism 13 seals the left end of the connecting pipe 1 14 and the two ends of the connecting pipe 2 15 and the connecting pipe 3 16, the exhaust gas leakage will not be caused while the adsorption mechanism 5 is quickly replaced.

[0025] Working principle: Before the present invention is used, the lower through hole 11 is connected to the cooling water supply device, the upper through hole 11 is connected to the cooling water recovery pipe, the air inlet end of the cooling pipe 83 is in contact with the glycine production waste gas supply pipe after the wet scrubber treatment, and the lower right installation hole 12 is connected to the subsequent treatment device; When the present invention is used, cooling water enters the liquid inlet chamber 9 from the lower through hole 11. With the entry of cooling water, the cooling water will enter the interior of the cooling chamber 6 and the condensation chamber 7, and finally be discharged from the upper through hole 11. The control motor 2 drives the connecting shaft 3 and the rotating frame 4 to rotate. When the arc-shaped slide groove of the adsorption shell 51 contacts the sliding head 131, the adsorption shell 51 continues to rotate, and the sliding head 131 will move outward until the sliding head 131 enters the opening inside the adsorption shell 51. The control motor 2 will stop rotating. At this time, all the sliding heads 131 are located in the opening of the adsorption shell 51. Then, the electromagnet 57 is energized to generate a magnetic field, and at the same time, a suction force is generated on the permanent magnet 54 and the permanent magnet block 134, so that the permanent magnet block 134 and the permanent magnet 54 will move the interior of the adsorption shell 51. The permanent magnet block 134 moves toward the interior of the adsorption shell 51, and the sealing block 136 moves accordingly, so that the mounting hole 12 is connected to the interior of the adsorption shell 51. The glycine production waste gas treated by the wet scrubber enters the interior of the cooling tube 83 through the air inlet end of the cooling tube 83. Since the interior of the condensation chamber 7 is filled with cooling water, the water vapor in the gas entering can be condensed into liquid. The condensed water will slide downward along the cooling tube 83, enter the collecting tube 82, and finally enter the lower space of the rotating plate 81. The waste gas after dehydration enters the connecting pipe 1 14 from the exhaust end of the cooling tube 83, and then passes through the sealing mechanism 13 to enter the interior of the left adsorption shell 51. Ammonia and formaldehyde in the waste gas will be adsorbed by the activated carbon 58, and the remaining gas will enter the middle adsorption shell 51 through the connecting pipe 3 16, and after being adsorbed by the activated carbon 58, enter the rightmost adsorption shell 51 through the connecting pipe 2 15, and finally enter the existing subsequent treatment device from the mounting hole 12 on the lower right side; The cooling water inside the cooling chamber 6 will cool down the adsorption shell 51 and the activated carbon 58, thereby increasing the adsorption capacity of the activated carbon 58. When the activated carbon 58 on the far left is saturated with adsorption, the exhaust gas is first stopped, and then the electromagnet 57 is reversely energized to generate a magnetic field, and at the same time, a repulsive force is generated on the permanent magnet 54 and the permanent magnet block 134, so that the sliding plate 56 seals the opening of the adsorption shell 51, and the permanent magnet block 134 will drive the sliding head 131 to move upward, and then the rotating frame 4 rotates counterclockwise by ninety degrees, and the adsorption mechanism 5 originally at the rear of the middle part is rotated to the far left, and the adsorption mechanism 5 at the front of the middle part will be rotated to the far right. During the process, since the sealing mechanism 13 seals the left end of the connecting pipe 1 14 and the two ends of the connecting pipe 2 15 and the connecting pipe 3 16, the adsorption mechanism 5 can be quickly replaced without causing leakage of exhaust gas. The adsorption mechanism 5 for absorbing saturated ammonia and formaldehyde is removed and placed in a sodium cyanide solution for producing glycine. The electromagnet 57 is energized to generate a magnetic field, which causes the sliding plate 56 to move downward, and the solution enters the interior of the adsorption shell 51. The cyanide ions (CN⁻) in the solution will approach the activated carbon 58, thereby accelerating the consumption of ammonia and formaldehyde adsorbed by the activated carbon 58. Since the activated carbon 58 has a greater adsorption capacity for water than other components, when the activated carbon 58 is taken out, the moisture of the sodium cyanide solution will be taken away. Although the sodium cyanide is consumed, the concentration of the sodium cyanide solution will remain unchanged or increase. When the two adsorption shells 51 are opened to take out the activated carbon 58, the moisture of the activated carbon 58 can be taken away by heating or other means, thereby realizing the regeneration of the activated carbon 58. When a certain amount of water accumulates at the bottom of the rotating plate 81, the water supply to the interior of the lower through hole 11 can be stopped and the cooling water in the liquid inlet chamber 9 can be emptied. The control valve 85 is opened, and the water at the bottom of the rotating plate 81 will be discharged from the drain pipe 84.
