Description

A biopharmaceutical fermentation tank tail gas purification equipment

Technical Field

The invention relates to the technical field of waste gas purification equipment, and in particular to a biopharmaceutical fermentation tank tail gas purification equipment.

Background Art

With the rapid development of modern biotechnology, bio-fermentation drugs have been widely used in clinical practice, making great contributions to human health. Due to the large amount of air used in biopharmaceutical fermentation, a large amount of untreated waste gas is discharged into the atmosphere, causing some fermentation metabolites to be carried out with the fermentation waste gas, and even producing special unpleasant odors, that is, the concentration of its drug components or intermediates in the air continues to increase. These waste gases are harmful to the human body and the environment. Therefore, the bio-fermentation waste gas must be purified and discharged in compliance with the standards.

Biological fermentation waste gas is relatively complex, and generally needs to be treated by a variety of treatment methods such as spraying, adsorption, and catalytic combustion towers before it can reach the release standard. Spraying is mainly achieved through a spray tower, where the tail gas enters the interior of the tower from below the spray, and the tail gas passes through the packing layer and the spray gas during the rising process to remove harmful substances in the tail gas. When the tail gas enters the interior of the tower, the tail gas flowing into the packing area away from the air inlet side is less, and the absorption liquid sprayed here absorbs less harmful substances. At the same time, when processing some gases that need to pass through at high speed (such as hydrogen sulfide, which is corrosive to equipment and accelerates equipment aging, and needs to be removed as quickly as possible when processing hydrogen sulfide), it is necessary to speed up its purification speed. Therefore, those skilled in the art provide a biopharmaceutical fermentation tank tail gas purification device to solve the problems raised in the above background technology.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Please refer to Figures 1 to 10. In this embodiment, a biopharmaceutical fermentation tank tail gas purification device is provided, including a tower body 1, an air outlet 3 is provided on the top of the tower body 1, a spray device 4 is installed on one side of the tower body 1, the spray device 4 includes a spray pipe 41, the spray pipe 41 is located inside the tower body 1, a packing rotating device 5 that can drive the packing to rotate is installed inside the tower body 1, the packing rotating device 5 is located below the spray pipe 41, and an air inlet 2 is provided on one side of the tower body 1, and the air inlet 2 is located below the packing rotating device 5.

When in use, the exhaust gas pipeline is connected through the air inlet 2, and the exhaust gas enters the lower part of the tower body 1 through the air inlet 2. The absorption liquid is sprayed into the tower body 1 through the spray device 4. When the absorption liquid passes through the filler, the contact area with the exhaust gas is increased, thereby absorbing the harmful substances in the exhaust gas. The filler is driven to approach the air inlet 2 in turn through the filler rotating device 5, so that the absorption liquid on the outside of the filler contacts with more exhaust gas in turn, so that the absorption liquid is fully in contact with the exhaust gas. After absorption, the absorption liquid falls to the lower part of the tower body 1. When the absorption liquid has not reached saturation, it is recycled through the spray device 4. The gas after the harmful substances are absorbed is discharged from the tower body 1 through the air outlet 3 for subsequent treatment.

In a further embodiment, referring to FIG. 2 , a demister 31 is installed in the air outlet 3 .

By designing a specific structure of the demister 31, such as a corrugated plate or a grid, the liquid droplets in the air flow are captured when they hit these structures, thereby reducing the water vapor in the exhaust gas.

In a further embodiment, referring to Figures 1 to 2, the spray device 4 also includes a delivery pump 44, one end of which is connected to the bottom of the tower body 1, a delivery pipe 43 is connected above the delivery pump 44, the delivery pipe 43 is connected to the spray pipe 41, and a plurality of diffusion plates 42 are installed on the spray pipe 41.

The unsaturated absorption liquid at the bottom of the tower body 1 is sucked in by the delivery pump 44 and delivered to the spray pipe 41 through the delivery pipe 43 for continued spraying. The diffusion plate 42 increases the area covered by the absorption liquid during spraying.

In a further embodiment, referring to FIG. 3 , the filler rotating device 5 comprises a rotating plate 51 having a plurality of holes, a plurality of partition plates 1 54 being installed above the rotating plate 51 , a plurality of partition plates 2 55 being installed below the rotating plate 51 , and the rotating plate 51 being connected to a driving device to drive the rotating plate 51 to rotate.

A filler is placed on the rotating plate 51, and the filler is divided into sections by a partition 1 54. The exhaust gas entering the tower body 1 is isolated by multiple partition 2s 55, so that the exhaust gas evenly and sequentially passes through the areas between the multiple partition 2s 55 and rises to the partition 1 54, so that the absorption liquid on the outside of the filler reacts and can fall to the bottom of the tower body 1 through multiple holes for recycling.

In a further embodiment, referring to FIGS. 3 and 8 , a driving slot 512 is provided on the rotating plate 51 , a driving motor 56 is installed below the tower body 1 , a rotating shaft 57 is connected above the driving motor 56 , and an upper end of the rotating shaft 57 is inserted into the driving slot 512 .

The driving motor 56 is started to drive the rotating shaft 57 to rotate. The cross-section of the upper end of the rotating shaft 57 is the same as the cross-section of the driving groove 512, so the rotating shaft 57 can be inserted into the driving groove 512. The cross-section shape is not circular, so that the rotating shaft 57 cannot rotate relative to the driving groove 512. The rotation of the rotating shaft 57 drives the rotating plate 51 to rotate.

In a further embodiment, referring to Figures 3 to 4, a support ring 14 is installed inside the tower body 1 below the rotating plate 51, a sealing ring 53 is fixedly connected below the rotating plate 51, and the sealing ring 53 is fitted with the inner side of the support ring 14, and a baffle 1 13 is installed inside the tower body 1 above the rotating plate 51, a baffle 2 52 is fixedly connected above the rotating plate 51, and the baffle 2 52 is fitted with the outer side of the baffle 1 13.

The support ring 14 is used to provide support for the rotating plate 51, and the sealing ring 53 is fitted with the inner side of the support ring 14, so that the falling absorption liquid and harmful substances in the exhaust gas cannot enter the support ring 14, thereby protecting the ball bearings on the support ring 14, and the baffle 1 13 and baffle 2 52 are used to make the falling absorption liquid fall along the baffle 1 13 to the rotating plate 51, and cannot enter the baffle 1 13, baffle 2 52 and the inside of the tower body 1, thereby protecting the structure between the baffle 1 13, baffle 2 52 and the tower body 1 to avoid corrosion and damage.

In a further embodiment, referring to FIG. 7 , a plurality of slots are formed inside the support ring 14 , steel balls 141 are installed inside the slots, and springs 142 are provided below the steel balls 141 .

The rotating plate 51 is supported by the steel ball 141, thereby reducing the friction between the rotating plate 51 and the support ring 14, making it easier for the rotating plate 51 to rotate. The steel ball 141 is supported by the spring 142, so that the rotating plate 51 can be buffered and supported when the rotating plate 51 vibrates.

In a further embodiment, referring to Figures 4 and 5, a plurality of connecting rods 58 are fixedly connected to the peripheral side of the rotating plate 51, a groove 11 is provided on the inner wall of the tower body 1 located outside the rotating plate 51, a plurality of inclined movable support plates 12 are installed inside the groove 11, a plurality of movable grooves 111 are opened inside the groove 11, and the movable support plates 12 can rotate through the movable grooves 111.

The connecting rod 58 rotates together with the rotating plate 51. When the rotating plate 51 rotates clockwise, the connecting rod 58 passes under the movable support plate 12 in sequence. When the connecting rod 58 passes under the movable support plate 12 again, it pushes the movable support plate 12 to rotate in sequence (through the movable groove 111, one end of the movable support plate 12 can be raised and lifted, so that the movable support plate 12 as a whole is higher than the height of the connecting rod 58), so that the connecting rod 58 can pass under the movable support plate 12, and the rotating plate 51 rotates normally.

When the rotating plate 51 rotates counterclockwise, the height of the connecting rod 58 is higher than the height of the rotating end below the movable support plate 12, and the connecting rod 58 rises along the inclined surface of the movable support plate 12 (one end of the movable support plate 12 is located at the bottom of the movable groove 111, and one end of the movable support plate 12 cannot rotate downward), and the connecting rod 58 drives the rotating plate 51 to rise together, and the horizontal height of the rotating plate 51 is thereby raised, and the filler on the rotating plate 51 rises accordingly. When the connecting rod 58 passes through the higher end of the movable support plate 12, the connecting rod 58 loses support and falls under the action of gravity, and the rotating plate 51 falls. During the falling process of the rotating plate 51, the filler thereon gradually falls after losing support, thereby forming gaps between the fillers, thereby reducing the resistance of the exhaust gas flow, allowing the exhaust gas to pass quickly.

Note that the different effects of clockwise rotation and counterclockwise rotation are related to the inclination of the movable support plate 12. When the inclination of the movable support plate 12 is higher on the left and lower on the right (as shown in FIG. 5 ), the rotation effect is the same as described above. When the inclination of the movable support plate 12 is lower on the left and higher on the right, the rotation effect is opposite to the above.

In a further embodiment, referring to FIG. 6 , one end of the movable support plate 12 is fixedly connected to a rotating support rod 121 , and the other end of the movable support plate 12 is slidably connected to a movable support rod 122 , and one end of the movable support rod 122 is located inside the movable groove 111 .

The movable support plate 12 is rotatably connected to the inner wall of the tower body 1 by rotating the support rod 121. Since the movable support plate 12 is a straight rod and the inner wall of the tower body 1 is a curved surface, when the movable support plate 12 rotates around the rotating support rod 121, the distance between the other end of the movable support plate 12 and the tower body 1 changes. Relative displacement can occur between the movable support rod 122 and the movable support plate 12. When the movable support plate 12 rotates, the movable support rod 122 can also be located inside the movable groove 111 to ensure that the movable support plate 12 can rotate.

In a further embodiment, referring to Figures 8 to 10, a plurality of connecting grooves 511 are provided on the rotating plate 51, the positions of the partition 1 54 and the partition 2 55 are aligned vertically, the connecting grooves 511 are located between the partition 1 54 and the partition 2 55, an accumulation groove 541 is provided on the top of the partition 1 54, a plurality of downward sliding grooves 542 are provided on the side of the partition 1 54, and a plurality of ventilation grooves 551 are provided on the side of the partition 2 55.

The connecting groove 511 is located between the partition 1 54 and the partition 2 55, so that the downward groove 542 on the partition 1 54 and the partition 2 55 is connected with the ventilation groove 551. When the exhaust gas enters the interior of the tower body 1, in addition to entering the top of the tower body 1 through the holes on the rotating plate 51, it can also rise to the downward groove 542 through the ventilation groove 551. During the spraying process, the absorption liquid is sprinkled on the partition 1 54, and the absorption liquid content on the partition 1 54 is increased through the downward groove 542, so that the exhaust gas reacts with the absorption liquid on the outside of the partition 1 54 when passing through the partition 1 54, and harmful substances in the gas are removed. At the same time, the sprayed absorption liquid can be accumulated through the accumulation groove 541. The accumulation groove 541 is connected with the downward grooves 542 on both sides. The accumulated absorption liquid falls from the downward grooves 542 on both sides, further increasing the absorption liquid on the partition 1 54.

At the same time, the downward sliding grooves 542 on both sides of the partition 1 54 are spaced apart from each other, and the ventilation grooves 551 on the partition 2 55 are spaced apart from each other, so as to avoid the grooves making the thickness of the partition 1 54 and the partition 2 55 too small, thereby reducing the structural strength of the partition 1 54 and the partition 2 55.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
