Description
Technical Field

Background
Packed columns are also known as packed columns. Mass transfer equipment commonly used in chemical production. Mainly comprises a cylindrical tower body, a filler (solid matters with various shapes and used for increasing the area between two phase fluids and enhancing mass transfer between two phases) stacked in the tower, and the like. Is used for absorption, distillation, extraction, etc.
The packing tower uses packing as a basic component for gas-liquid contact and mass transfer, liquid flows from top to bottom in a film shape on the surface of the packing, gas flows from bottom to top in a continuous phase and is transferred to the liquid, and mass transfer and heat transfer between the gas and the liquid are carried out. The component concentration and temperature of the two phases vary continuously along the column height. The packed tower belongs to gas-liquid mass transfer equipment with differential contact.
As the liquid flows down the packing there is a tendency to concentrate toward the column wall, causing the flow of liquid near the column wall to increase gradually, a phenomenon known as wall flow. The wall flow effect causes uneven distribution of gas-liquid phases in the packing layer, thereby reducing mass transfer efficiency.
The prior Chinese patent with publication number of CN113274866A discloses a wall flow preventing efficient packing tower, and the patent has the following defects:
firstly, the device limits the spraying area of the spray head through the limiting disc, so as to prevent the spray liquid from spraying on the inner wall of the upper end of the tower body and further prevent the liquid from sagging on the inner wall of the tower body, but after the high-temperature gas rises, the temperature of the inner wall of the tower body is lower than the temperature of the center of the tower body, so that after the high-temperature gas rises to the upper end of the tower body, a small part of gas contacts with the inner wall of the tower body to liquefy and is attached to the inner wall of the tower body, and therefore, the liquid is prevented from sagging on the inner wall of the tower body, and the method adopted by the patent can not completely prevent the sagging of the liquid;
secondly, the elastic membrane in the device ejects liquid to the filler in a magnetic attraction on-off mode, and as the magnetic material providing magnetic attraction is exposed outside for a long time, the magnetism of the magnetic material is gradually reduced under the influence of rising temperature gas, and finally the elastic membrane cannot be attracted magnetically to generate elasticity;
thirdly, the air pipes in the device are spirally distributed, but the spraying direction of the lower spray head connected with the air pipes is fixed, namely, the lower spray head always sprays the air along a straight line no matter how the air pipes are arranged, so that the spiral spraying of the air in the patent is avoided.

The cooling process liquid flows into a liquid distributor through a water inlet pipe 4 at the upper end of the tower body 1, the cooling process liquid is sprayed onto a combined packing cylinder 6 positioned in a second packing region in a mist form through the liquid distributor, the atomized liquid flows into the combined packing cylinder 6 positioned in a first packing region along the packing in the inner layer and the outer layer of the combined packing cylinder 6 after falling into the combined packing cylinder 6, and the atomized liquid flows from top to bottom in a film form on the surface layer of the packing when passing through each combined packing cylinder 6;
the high-temperature waste gas is continuously discharged into the packed tower through the air inlet 2 at the lower end of the tower body 1, and then the high-temperature waste gas gradually rises in the tower body 1, the upward flow of the high-temperature waste gas is accelerated through the negative pressure fan 8 in the process, when the high-temperature waste gas rises upwards to contact with atomized liquid, the gas-liquid mass transfer and the heat transfer are carried out, and after that, the purified gas continuously rises and is discharged from the air outlet 5, the liquid continuously descends and is discharged from the water outlet 3;
the rising speed of the high-temperature gas is slow in the initial state, and after the high-temperature gas passes through the first packing area, the gas is consumed in the mass transfer and heat transfer process with the atomized liquid, so that the rising amount of the high-temperature gas to the second packing area is slightly lower, and in order to increase the rising speed of the high-temperature waste gas, the upward exhaust amount is increased, and the gas-liquid exchange efficiency is improved, so that an air entraining piece for accelerating and upwards exhausting the high-temperature waste gas is arranged;
the reason for the wall flow effect formed in conventional packed columns is: the packing is in direct contact with the inner wall of the tower body 1, so when liquid flows downwards along the packing layer, the liquid has a tendency to gradually concentrate towards the inner wall of the tower due to the special shape of the packing, the liquid flow near the inner wall of the tower is gradually increased, and the gas flow near the inner wall of the tower is relatively smaller than the gas flow in the tower, so when the packing tower is higher, the wall flow effect can cause uneven distribution of gas-liquid two phases in the packing layer, thereby reducing mass transfer efficiency;
the inner layer of each combined packing cylinder 6 is uniformly and uniformly packed, the outer layer of each combined packing cylinder 6 is uniformly and randomly packed, the area of the inner layer of each combined packing cylinder 6 is larger than that of the outer layer, the inner layer of each combined packing cylinder 6 is fixed at the center of the tower body 1, the gas-liquid two-phase intersection amount is large, so that the gas-liquid two-phase treatment capacity is improved through the structured packing, the outer layer of each combined packing cylinder 6 is close to the inner wall of the tower body 1, the temperature is low, high-temperature waste gas is easy to cool and form liquid drops on the packing, the random packing with better corrosion resistance is used as a medium for gas-liquid two-phase mass transfer, and the outer layer of each combined packing cylinder 6 can rotate, so that the random packing with lighter weight than the structured packing is also convenient for the rotation of the outer layer of the combined packing cylinder 6;
the arc scraping strip 7 does not need a higher rotating speed when working, but the negative pressure fan 8 needs a higher rotating speed when working to accelerate and lead the high-temperature waste gas, so the rotating speed of the driving shaft 41 for driving the negative pressure fan 8 to rotate is increased through the speed change mechanism of the device.
In order to reveal the specific structure of each combined packing sleeve 6, the following features are provided:
each combined packing cylinder 6 comprises an inner cylinder 9 and an annular cylinder 10 which are coaxial, the top of the inner cylinder 9 is of an opening structure, two annular baffle plates 15 are arranged between the annular cylinder 10 and the inner cylinder 9 in a forming mode, a first supporting grid plate 12 is fixedly arranged in a first packing area and a second packing area, the tops of the first supporting grid plates 12 are fixedly arranged on the two annular baffle plates 11 respectively, the annular cylinder 10 is sleeved on the outer wall of the inner cylinder 9 through a plurality of first bearings 13, the plurality of first bearings 13 are uniformly distributed along the axial direction of the inner cylinder 9, the top of the annular cylinder 10 is of an opening structure, the bottom of the annular cylinder 9 is provided with an annular grid plate 14 positioned above the first supporting grid plate 12, two annular baffle plates 15 are arranged between the annular cylinder 10 and the inner cylinder 9 and correspond to the upper end and the lower end of the annular cylinder 10 respectively, each annular baffle plate 15 is coaxial with the annular cylinder 10, the outer layer ring of each annular baffle plate 15 is fixedly connected with the inner layer ring of the annular cylinder 10, the inner layer ring of each annular baffle plate 15 is attached to the outer wall of the inner cylinder 9, the inner cylinder 9 is of the combined packing cylinder 6, the annular cylinder 6 is provided with the outer layer of the combined packing cylinders 6, and the number of the combined packing cylinders 6 is equal to the outer layer 7 of the combined packing cylinders 7.

Working principle:
the cooling process liquid flows into a liquid distributor through a water inlet pipe 4 at the upper end of the tower body 1, the cooling process liquid is sprayed onto a combined packing cylinder 6 positioned in a second packing region in a mist form through the liquid distributor, the atomized liquid flows into the combined packing cylinder 6 positioned in a first packing region along the packing in the inner layer and the outer layer of the combined packing cylinder 6 after falling into the combined packing cylinder 6, and the atomized liquid flows from top to bottom in a film form on the surface layer of the packing when passing through each combined packing cylinder 6;
the high-temperature waste gas is continuously discharged into the packed tower through the air inlet 2 at the lower end of the tower body 1, and then the high-temperature waste gas gradually rises in the tower body 1, the upward flow of the high-temperature waste gas is accelerated through the negative pressure fan 8 in the process, when the high-temperature waste gas rises upwards to contact with atomized liquid, the gas-liquid mass transfer and the heat transfer are carried out, and after that, the purified gas continuously rises and is discharged from the air outlet 5, the liquid continuously descends and is discharged from the water outlet 3;
the rising speed of the high-temperature gas is slow in the initial state, and after the high-temperature gas passes through the first packing area, the gas is consumed in the mass transfer and heat transfer process with the atomized liquid, so that the rising amount of the high-temperature gas to the second packing area is slightly lower, and in order to increase the rising speed of the high-temperature waste gas, the upward exhaust amount is increased, and the gas-liquid exchange efficiency is improved, so that an air entraining piece for accelerating and upwards exhausting the high-temperature waste gas is arranged;
the reason for the wall flow effect formed in conventional packed columns is: the packing is in direct contact with the inner wall of the tower body 1, so when liquid flows downwards along the packing layer, the liquid has a tendency to gradually concentrate towards the inner wall of the tower due to the special shape of the packing, the liquid flow near the inner wall of the tower is gradually increased, and the gas flow near the inner wall of the tower is relatively smaller than the gas flow in the tower, so when the packing tower is higher, the wall flow effect can cause uneven distribution of gas-liquid two phases in the packing layer, thereby reducing mass transfer efficiency;
the inner layer of each combined packing cylinder 6 is uniformly and uniformly packed, the outer layer of each combined packing cylinder 6 is uniformly and randomly packed, the area of the inner layer of each combined packing cylinder 6 is larger than that of the outer layer, the inner layer of each combined packing cylinder 6 is fixed at the center of the tower body 1, the gas-liquid two-phase intersection amount is large, so that the gas-liquid two-phase treatment capacity is improved through the structured packing, the outer layer of each combined packing cylinder 6 is close to the inner wall of the tower body 1, the temperature is low, high-temperature waste gas is easy to cool and form liquid drops on the packing, the random packing with better corrosion resistance is used as a medium for gas-liquid two-phase mass transfer, and the outer layer of each combined packing cylinder 6 can rotate, so that the random packing with lighter weight than the structured packing is also convenient for the rotation of the outer layer of the combined packing cylinder 6;
the arc scraping strip 7 does not need a higher rotating speed when working, but the negative pressure fan 8 needs a higher rotating speed when working to accelerate and lead the high-temperature waste gas, so the rotating speed of the driving shaft 41 for driving the negative pressure fan 8 to rotate is increased through the speed change mechanism of the device.
