Description

Technical Field

[0001] The utility model relates to the technical field of acetaldehyde absorption treatment, in particular to an integral acetaldehyde absorption tower device. Background Art

[0002] Acetaldehyde is an organic compound. It is a colorless, transparent liquid with a pungent odor, and is easily soluble in organic solvents such as water, ethanol, and ether. Acetaldehyde plays an important role in chemical and biological processes and is a key intermediate in many industrial chemical reactions and metabolic processes in organisms. Acetaldehyde is an organic compound with a pungent odor, and is flammable and volatile. It is miscible with organic solvents such as water, ethanol, and ether. Acetaldehyde is harmful to the human body and may enter the human body through inhalation, ingestion, and absorption through the skin, causing damage to health. It requires the use of an integral absorption tower device for treatment.

[0003] Common integrated acetaldehyde absorption tower devices are usually composed of tower body, absorption section, filler, liquid distributor, absorption liquid pump, drainage system and other auxiliary equipment. First, acetaldehyde is introduced into the interior of the device, and the absorption liquid is sprayed onto the filler layer. The liquid distributor evenly distributes the absorption liquid on the filler layer. The acetaldehyde gas contacts the sprayed absorption liquid in countercurrent. The absorption liquid pump circulates the absorption liquid to the top of the tower body. The drainage system is used to regularly discharge the absorption liquid to the external subsequent treatment equipment.

[0004] In the traditional integral acetaldehyde absorption tower device, a nozzle is added to the top of the inner cavity of the device, and the absorption liquid is sprayed on the filler through the nozzle. However, the position of the nozzle is usually fixed and cannot be adjusted, so the absorption liquid cannot be sprayed evenly on the filler, which reduces the absorption effect of acetaldehyde and causes damage to the filler. In order to solve the above problems, some integral acetaldehyde absorption tower devices are equipped with a liquid distributor above the filler. Since the liquid distributor usually adopts a porous plate or a nozzle array, the absorption liquid is pumped into the pump body and the pipeline, and the incoming absorption liquid can be sprayed evenly on the filler, which accelerates the absorption effect of acetaldehyde and avoids damage to the filler. However, in this way, due to the manufacturing, installation and debugging of the liquid distributor, not only the use cost of the device is increased, but also the difficulty of installation and operation is increased. For this reason, an integral acetaldehyde absorption tower device is proposed. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the deficiencies in the prior art, the utility model provides an integrated acetaldehyde absorption tower device to solve the above-mentioned technical problems that not only the use cost of the device is increased, but also the installation and operation difficulty are increased.

[0007] (II) Technical solution

[0008] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an integrated acetaldehyde absorption tower device, comprising:

[0009] A tower shell, and fans and liquid displacement pumps arranged at the lower parts of both sides of the tower shell, a liquid storage tank is installed on the back of the tower shell, and a pump body is connected to the top of the liquid storage tank;

[0010] The filler is arranged at the center of the inner cavity of the tower shell, and a spray cylinder is added directly above the top of the filler, and spray holes are evenly opened at the bottom center and front and rear ends of the spray cylinder, and the spray cylinder is connected to the pump body;

[0011] The connecting side blocks are arranged at both ends of the spray barrel, and a driven wheel is added to the outside of the connecting side blocks, and the end of the spray barrel passes through the connecting side blocks and is connected to the driven wheel. The top of the driven wheel is meshed with a driving wheel, and a second driving motor is coaxially connected to the outside of the driving wheel. Threaded screws are added to both sides of the tower shell, and a sliding block is sleeved in the center of the threaded screw and connected to the connecting side blocks. The threaded screw is coaxially connected to the third driving motor. Acetaldehyde is transported to the inside of the tower shell through the fan to rise, and the pump body transports the absorption liquid in the liquid storage tank to the inside of the spray barrel and sprays it to the filler through the spray hole. The second driving motor drives the driven wheel through the driving wheel, and the driven wheel drives the spray barrel to rotate. The third driving motor drives the threaded screw to rotate, so that the sliding block drives the connecting side block to translate according to the direction of the threaded screw. On the one hand, by rotating and translating the spray barrel, the absorption liquid can be evenly sprayed on the filler and react with acetaldehyde, without the need for a liquid distributor, thereby reducing the use cost and the difficulty of installation and operation of the device; on the other hand, compared with the traditional method of using adjustable brackets, the movement and angle adjustment structure of the device is simple, the use cost is low, and it is located outside for easy inspection and maintenance.

[0012] Preferably, a first drive motor is installed at the bottom center of the tower shell, and a rotating shaft is added at the bottom center of the inner cavity of the tower shell and is coaxially connected to the first drive motor. The first drive motor drives the rotating shaft to rotate on the tower shell and adjusts the direction of the rotating shaft.

[0013] Preferably, a lower fixing block is installed at the lower center of the inner cavity of the tower shell, and guide blocks are provided around the bottom of the lower fixing block, and an upper fixing block is installed on the top of the lower fixing block. The guide blocks can concentrate acetaldehyde at the bottom center of the lower fixing block, thereby preventing acetaldehyde from being unable to pass through the lower fixing block.

[0014] Preferably, a vent plate is provided at the center of the inner cavity of the lower fixed block and the upper fixed block, and the adjacent vent plates correspond to each other, and the vent plate of the lower fixed block is connected to the end of the rotating shaft. The acetaldehyde can rise and contact the filler through the vent plates of the lower fixed block and the upper fixed block. At the same time, the vent plate of the lower fixed block can rotate under the drive of the rotating shaft and be misaligned with the vent plate of the upper fixed block. Not only can the amount of acetaldehyde entering be controlled so that a comprehensive reaction treatment can be carried out, and the occurrence of excessive acetaldehyde entering and inability to carry out a comprehensive reaction treatment can be avoided, but also the acetaldehyde can be divided into multiple strands through the vent plate, and uniformly contact and react with various parts of the filler. At the same time, a guide block can be added around the top of the upper fixed block so that the absorption liquid can descend to the bottom of the inner cavity of the tower shell through the vent plate and be discharged by the drainage pump to avoid the phenomenon that part of the absorption liquid remains on the top of the upper fixed block.

[0015] Preferably, the upper parts of both sides of the tower shell are provided with chutes, and the connecting side blocks are located at the inner center of the chutes, and the outer sides of the connecting side blocks are provided with side baffles, which fit the outer ends of the chutes. The connecting side blocks can be translated along the chutes, and acetaldehyde leakage can be avoided under the obstruction of the side baffles.

[0016] Preferably, a flow diversion conduit is connected to the center of the top of the pump body, and the end of the flow diversion conduit extends inward through the outer wall of the connecting side block and is connected to the end of the spray barrel. The pump body transports the absorption liquid inward through the two ends of the spray barrel through the flow diversion conduit, avoiding the phenomenon that the spray effect of one part of the spray barrel is strong and the spray effect of another part is weak, so that the filler cannot be sprayed evenly.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the utility model provides an integrated acetaldehyde absorption tower device, which has the following beneficial effects:

[0019] The integrated acetaldehyde absorption tower device uses a fan to transport acetaldehyde to the inside of the tower shell for rising, and the pump body transports the absorption liquid in the liquid storage tank to the inside of the spray barrel and sprays it to the filler through the spray hole. The second drive motor drives the driven wheel through the active wheel, and the driven wheel drives the spray barrel to rotate. The third drive motor drives the threaded screw to rotate, so that the sliding block drives the connecting side block to translate according to the direction of the threaded screw. Compared with the traditional method of using adjustable brackets, the movement and angle adjustment structure of this device is simple and the use cost is low. At the same time, it is convenient to carry out inspection and maintenance operations outside, so that the absorption liquid can be evenly sprayed on the filler. By rotating and translating the spray barrel, the absorption liquid can be evenly sprayed on the filler and contacted with acetaldehyde, without the need to use a liquid distributor, thereby reducing the use cost of the device and the difficulty of installation and operation.
