Description
Technical Field
The invention relates to the technical field of stripping towers, in particular to an amine stripping device based on efficient packing.
Background
Natural gas is a recognized clean energy source, has the advantages of high heat generation, less pollution, convenient use and the like, and at present, the demand of the natural gas is larger and larger, and higher requirements are put on the storage and transportation efficiency of the natural gas. The natural gas must be pretreated before liquefaction, wherein deep decarbonization is an important link of pretreatment, the content of CO 2 in the natural gas before liquefaction is usually required to be lower than 50ppm, and currently, the main method for decarbonization of the natural gas is an amine absorption method, namely, an amine liquid is adopted to absorb CO 2 in the raw material natural gas.
For example, patent document CN 106268176B discloses a deep decarbonization process of raw natural gas, which adopts the following steps: 1) Pressurizing the decarburization absorption tower; 2) Continuously injecting an alcohol amine solution with a circulating amount into the top of the absorption tower by adopting a centrifugal pump; 3) After the temperature and pressure of the decarbonization absorption tower are stable, continuously introducing raw material natural gas into the bottom of the decarbonization absorption tower, and allowing the purified natural gas obtained after CO 2 is absorbed and decarbonized by alcohol amine solution to flow out from the top of the decarbonization absorption tower; 4) The alcohol amine solution absorbed with CO 2 is discharged from the bottom of the decarbonization absorption tower, regenerated by a regeneration system and returned to the top of the decarbonization absorption tower through a centrifugal pump for recycling. It should be noted that: the absorber disclosed in this patent document is a stripping column for decarbonizing natural gas.
However, the above patent has certain technical drawbacks in decarbonizing natural gas, and the following specific analysis is now performed: as is apparent from a combination of fig. 1 of the patent document, raw natural gas enters the absorption tower from the bottom of the absorption tower, alcohol amine solution enters the absorption tower from the top of the absorption tower, raw natural gas moves upward in the absorption tower because of being gas, alcohol amine solution moves downward in the absorption tower because of being liquid, raw natural gas and alcohol amine solution contact in countercurrent in the absorption tower, chemical reaction occurs between the raw natural gas and the alcohol amine solution during countercurrent contact, so that CO 2 in the raw natural gas is removed, and clean natural gas leaves the absorption tower from the top of the absorption tower. In order to effectively remove carbon dioxide in the raw natural gas, the gas-liquid two phases are fully contacted, and the longer the raw natural gas stays in the tower, the more the contact times of the gas-liquid two phases are, the easier the carbon dioxide in the raw natural gas is removed. However, in the above patent documents, the raw natural gas is only contacted with the amine liquid once in the absorption tower, and the residence time of the raw natural gas in the absorption tower is short, so that it is difficult to efficiently contact the amine liquid in the absorption tower in a comprehensive and repeated manner, and therefore, the actual decarbonization effect of the raw natural gas is not ideal. Meanwhile, due to the fact that the extracted raw natural gas has certain solid suspended matters such as calcium and magnesium ions to form particles, excessive impurities in the natural gas can affect the quality of the natural gas.
Based on this, an amine stripping device based on high-efficiency packing is now proposed.

An amine liquid feeding mechanism consisting of an amine liquid storage part and a suction part mounted on the amine liquid storage part, wherein one end of the suction part of the amine liquid feeding mechanism is connected with a hollow supporting part of the rotary amine liquid spraying component 40;
When the suction part of the amine liquid feeding mechanism can convey the amine liquid in the amine liquid storage part into the hollow supporting part of the rotary amine liquid spraying component 40, the hollow supporting part conveys the amine liquid into the rotary spraying part, and the rotary spraying part sprays the amine liquid into the inner cavity of the stripping tower body 20;
The main body of the driving part 30 can rotate at a high speed, and the rotary spraying part of the rotary amine liquid spraying part 40 can rotate at a high speed through the transmission cooperation with the transmission part 50, so that the amine liquid can permeate into the packing assembly 70 in a rotary spraying mode, and the amine liquid sprayed by the rotary spraying part of the rotary amine liquid spraying part 40 forms a rich liquid area above the inner cavity of the stripping tower body 20;
When the rotary spraying portion of the rotary amine liquid spraying member 40 rotates, the transmission shaft 60 can be rotated synchronously with the rotation of the rotary spraying portion of the rotary amine liquid spraying member 40, and both the packing assembly 70 and the getter 80 can be rotated synchronously with the rotation of the transmission shaft 60, and since the packing assembly 70 can be rotated synchronously at a high speed by the rotation of the transmission shaft 60, the amine liquid permeated in the packing assembly 70 can be uniformly distributed inside the packing assembly 70 at a high speed by the rotation of the packing assembly 70.

Example two
As shown in fig. 1-20, the improvement is based on the first embodiment:
further comprises: a heating mechanism 10; which is mounted at the bottom of the stripper column 20.
When the heating mechanism 10 works, the water in the heating mechanism can be heated, so that the water in the heating mechanism can be vaporized to form water vapor, and the water vapor can be emitted to the inner cavity of the stripping tower body 20 through the heating mechanism 10 and is filled in the inner cavity of the stripping tower body 20.
This embodiment can be used in combination with the first embodiment, specifically: when the getter 80 rotates at a high speed, the bottom of the inner cavity of the stripping tower body 20 is formed as an air inlet area, the middle and upper parts of the inner cavity of the stripping tower body 20 are formed as air outlet areas (as shown in fig. 17), and the steam generated by the heating mechanism 10 and the raw material natural gas entering from the air inlet pipe 202 are sucked upwards, so that the steam and the raw material natural gas can continuously pass through the packing assembly 70 when being sucked upwards, and in the process of penetrating the packing assembly 70, the steam and the raw material natural gas which move upwards can continuously contact with amine liquid in the packing assembly 70 in a countercurrent manner.
In this embodiment, when the water vapor is continuously sucked upwards by the air inlet area and continuously passes through the filler assembly 70, the heat of the inner cavity of the stripping tower body 20 can be uniformly distributed in the process of countercurrent upwards;
When the raw material natural gas is continuously sucked upwards by the air inlet area and continuously passes through the filler assembly 70, the raw material natural gas can continuously penetrate through the filler assembly 70 in the countercurrent upward process, the residence time of the raw material natural gas in the stripping tower body 20 is delayed in the process of penetrating through the filler assembly 70, the raw material natural gas can continuously contact with the amine liquid permeated in the filler assembly 70 in countercurrent, and in the contact process, the amine liquid and CO 2 in the raw material natural gas are subjected to chemical reaction, so that the raw material natural gas is effectively decarbonized.
Meanwhile, in the process that the raw natural gas upwards penetrates through the packing assembly 70, the packing assembly 70 rotates at a high speed, so that the raw natural gas can be fully contacted with the amine liquid permeated in the packing assembly 70 in the process that the packing assembly 70 rotates, and by means of the high-speed rotation of the packing assembly 70, vortex airflow moving upwards can be generated in the inner cavity of the stripping tower body 20, and the raw natural gas passes through the packing assembly 70 continuously in a spiral motion mode in the inner cavity of the stripping tower body 20 along with the vortex airflow, and in the process, the residence time of the raw natural gas on the packing assembly 70 can be effectively delayed, so that CO 2 in the raw natural gas can be fully contacted and reacted with the amine liquid.
When rising raw natural gas is in countercurrent contact with amine liquid permeated in the packing assembly 70, as the amine liquid and CO 2 in the raw natural gas generate chemical reaction, reaction products can adhere to the surface of the packing assembly 70 and in the penetrating gaps, rising water vapor can liquefy and form water in the process of contacting the inner wall of the stripping tower body 20 and the packing assembly 70, and the liquefied water vapor can dissolve in water in the process of contacting the packing assembly 70 and flow downwards to the bottom of the inner cavity of the stripping tower body 20 to form a lean liquid zone;
