Description

Technical Field

[0001] The invention relates to the technical field of degassing towers, and in particular to a rotary degassing tower for fatty acid production. Background Art

[0002] The degassing tower, also known as a carbon remover, is a device that uses the wind power of a fan to blow away free carbon dioxide in the liquid.

[0003] The structure of the degassing tower is mostly cylindrical tower structure, generally composed of a liquid distribution device, a packing layer (multi-faceted hollow plastic balls, corrugated plates, etc.) and a blasting device. The liquid enters the tower from the top, and is evenly sprayed on the surface of the packing by the liquid distribution device to form a liquid film. After contacting the air through the packing layer, it flows into the lower water collection tank. The air is blown in from the bottom of the tower by a blower and discharged from the top together with the carbon dioxide precipitated in the water.

[0004] However, in the prior art, during the fatty acid production process, the fatty acids need to be degassed. After the fatty acid liquid enters the tower body, its separation from the gas is not processed first. When the packing layer is blown by the blowing equipment, the packing will float on the top surface and the contact effect with the liquid is not good, resulting in poor degassing effect. Summary of the invention

[0005] The present invention proposes a rotary degassing tower for fatty acid production. Gas with a certain pressure enters from the upper part of the tower body and serves as a power to drive a rotary liquid separation mechanism and a stirring and shearing mechanism to operate. The liquid is first diverted and sheared to a certain extent, so that the gas molecules are partially separated from the liquid molecules. At the same time, using the gas as power also saves other power sources, and it can also be used as a blowing gas source.

[0006] To this end, the technical solution adopted by the present invention is as follows: a rotary degassing tower for fatty acid production, comprising a tower body, wherein the upper part of the tower body is provided with a liquid inlet and an air outlet, the lower part of the tower body is provided with a liquid outlet, the upper part of the tower body is provided with a rotary liquid separation mechanism connected to the liquid inlet, the lower part of the rotary liquid separation mechanism is provided with a stirring and shearing mechanism, the lower part of the stirring and shearing mechanism is provided with a filler guide mechanism, and also includes a linkage air supply mechanism that drives the rotary liquid separation mechanism and the stirring and shearing mechanism to rotate in opposite directions.

[0007] By adopting the above technical scheme: the liquid inlet is used to send the liquid into the tower body, the air outlet is used to blow the carbon dioxide and other gases out of the tower body, and the liquid outlet is used to discharge the degassed liquid out of the tower body. The rotary liquid separation mechanism in the present invention can rotate under the drive of the linkage air supply mechanism to disperse the liquid entering the tower body, and the liquid can be further stirred and sheared by the stirring and shearing mechanism at the bottom thereof, so that part of the carbon dioxide and other gases are separated from the liquid, and then enter the filler guide mechanism for further degassing. At the same time, the rotary liquid separation mechanism and the stirring and shearing mechanism rotate in the opposite direction, which further improves the diversion and shearing effect.

[0008] Optionally, the rotary liquid separation mechanism includes a pipeline connected to the liquid inlet, the pipeline is rotatably connected to a liquid separation pipe through a sealed bearing, the liquid separation pipe is connected to a liquid separation plate, and the lower side of the liquid separation plate is connected to a plurality of liquid separation spoiler components.

[0009] By adopting the above technical solution: the liquid separation tube can rotate relative to the pipeline to drive the liquid separation plate to rotate, forming a rotary liquid separation, and the liquid separation disturbance component is used to disperse the liquid from the liquid separation plate and perform disturbance to break up the liquid.

[0010] Optionally, the liquid separation spoiler assembly includes several groups of liquid separation plates connected to the lower part of the liquid separation plate, the ends of the two liquid separation plates in each group are close to each other, a spoiler is provided between the two liquid separation plates, several liquid separation holes are opened on the liquid separation plates, and an impeller is provided on the liquid separation tube, and the impeller is driven by a linkage air supply mechanism.

[0011] By adopting the above technical solution: the liquid separation sheet is provided with a through hole for discharging liquid, and the liquid separated from the two liquid separation sheets whose lower ends are close to each other can form a hedging effect, and the liquid can be further dispersed under the action of the spoiler.

[0012] Optionally, the stirring and shearing mechanism includes a hollow mounting hole plate fixed inside the tower body, the mounting hole plate also having holes to allow the liquid to leak down, a driving cavity is provided in the mounting hole plate, and an impeller 2 driven by a linkage air supply mechanism is rotatably connected in the driving cavity, the impeller 2 is connected to a rotating disk, and a plurality of stirring and shearing components are provided on the rotating disk.

[0013] By adopting the above technical solution: the blades of impeller one and impeller two are arranged in opposite ways, so that their rotation directions can be opposite, and impeller two can drive the rotating disk to rotate, and its rotation direction is opposite to that of the liquid separation disk. Firstly, the liquids can collide to form a certain collision shear, and secondly, the stirring and shearing mechanism on the upper part of the rotating disk can shear the liquid at the same time, further break up the liquid, and make it easier for the gas to separate from the liquid.

[0014] Optionally, the stirring and shearing assembly includes a plurality of groups of cross shearing blades arranged on the upper part of the rotating disk.

[0015] By adopting the above technical solution: the cross shears can shear the liquid, thereby further breaking up the liquid, making it easier for the gas to separate from the liquid.

[0016] Optionally, the linked air supply mechanism includes an air inlet pipe, the air inlet pipe is connected to cavity one for driving the impeller one to rotate, the cavity one is connected to a driving cavity through a pipeline, and the driving cavity is connected to a filling material guide mechanism.

[0017] By adopting the above technical solution: through an external high-pressure air source, the airflow passes through cavity one and drives impeller one to rotate, driving the liquid separation plate to rotate and separate the liquid. When the airflow passes through the driving cavity, it can drive impeller two to rotate, thereby driving the rotating plate to rotate. Finally, the airflow reaches the filler guide mechanism to form an aeration blowing effect, which has the effect of one power airflow with multiple uses.

[0018] Optionally, the filler guiding mechanism includes a liquid-passing gas separation plate fixed at the bottom of the tower body and connected to the driving cavity, and a guiding liquid-passing hood arranged on the upper part of the liquid-passing gas separation plate, and the liquid-passing gas separation plate and the guiding liquid-passing hood are filled with gas separation fillers.

[0019] By adopting the above technical solution: the liquid-passing gas separation disk also has leakage holes to facilitate the liquid to leak down, and the gas forms an aeration effect after passing through the liquid-passing gas separation disk, so that the gas separation filler is blown and continuously contacts with the liquid, which is convenient for the gas to be separated.

[0020] Optionally, a plurality of leakage holes and aeration holes are provided on the upper portion of the liquid-passing gas separation disk, and an aeration pipe with its end extending toward the periphery is also provided in the middle portion of the liquid-passing gas separation disk.

[0021] Optionally, the liquid-guiding cover is a mesh-shaped arc-shaped cover body, the inner arc of which faces the lower part of the tower body, and a filler reflux member is provided at the top of the inner arc.

[0022] Optionally, the filler return member includes a fluid disruptor disposed at the top of the inner arc of the arc-shaped cover, and the fluid disruptor is in an inverted cone shape.

[0023] By adopting the above technical solution: the aeration pipe extending toward the periphery at the end can drive the air separation filler to move, and at the same time can move downward after being guided by the arc-shaped cover body, and continuously tumble, so as to prevent the air separation filler from being blown to the top and staying still. This continuous tumbling motion can better separate the gas from the liquid. By setting an inverted cone-shaped disturbing body, the air separation filler can be further prompted to tumble, so as to better drive the gas to separate the liquid.

[0024] The working principle and beneficial effects of the present invention are:

[0025] 1. The rotary liquid separation mechanism in the present invention can rotate under the drive of the linkage gas supply mechanism to disperse the liquid entering the tower body. The liquid can be further stirred and sheared by the stirring and shearing mechanism at the bottom, so that part of the carbon dioxide and other gases are separated from the liquid and then enter the filler guide mechanism for further degassing. At the same time, the rotary liquid separation mechanism and the stirring and shearing mechanism rotate in the opposite direction, which further improves the effect of diversion and shearing, thereby improving the degassing effect.

[0026] 2. Through the external high-pressure gas source, the airflow passes through the cavity one and drives the impeller one to rotate, driving the liquid separation plate to rotate and separate the liquid. When the airflow passes through the driving cavity, it can drive the impeller two to rotate, thereby driving the rotating plate to rotate. Finally, the airflow reaches the filler guide mechanism to form the effect of aeration and blowing, which has the effect of one power airflow with multiple uses.

[0027] 3. The aeration pipe extending toward the periphery at the end can drive the gas separation filler to move, and at the same time, it can move downward after being guided by the arc-shaped cover body, and continuously tumble to prevent the gas separation filler from being blown to the top and not moving. This continuous tumbling motion can better separate the gas from the liquid. By setting an inverted cone-shaped disturbing body, the gas separation filler can be further prompted to tumble, which can better drive the gas to separate the liquid and improve the degassing effect.
