Description
Technical field
The utility model relates to operate the internals that gas and liquid collecting redistributes in the case that operating condition is shaken, specially a kind of chemical industry
Anti-shake dynamic gas and liquid collecting redistributor on knockout tower of mass transfer.
Background technique
With progress of the epoch, chemical production technical has long-range development, new production technology is to chemical production equipment
Requirement it is also higher and higher, especially tower and internals, new technology require the specification of tower increasing (diameter and height),
It asks the efficiency of internals higher and higher, while also to guarantee that it can work under complex environment operating condition, such as: land wind load
The platform in biggish region or sea, both operating conditions feature having the same are exactly shaken larger.
In land: if tower is relatively high, (the tower equipment height run at present has been more than 60 meters, some even 100
Meter or more), these equipment just will appear apparent shaking, more severe, the rolling at the top of tower of the bigger shaking of wind when meeting strong wind
Dynamic amplitude is maximum.Serious bias current and wall stream are formed when shaking in tower, forms liquid blank area, makes gas-liquid contact less than generation is short
Road causes the internals efficiency in tower to decline, and liquid distribution is ineffective, influences overall efficiency.
At sea on platform: China coastal seas natural gas resource is abundant, these marine energies abundant, need to utilize in order to obtain
Offshore platform is exploited, but needs to transport by processing after the extraction of some energy, such as the natural gas of offshore production,
In natural gas other than main component alkane, also contain CO2And H2S impurity, this, which just needs to increase to absorb on platform at sea, sets
Standby (such as absorption tower) is to CO2And H2S could be transported after carrying out removing processing.When absorption tower is at sea run, due to marine stormy waves
It is bigger, cause offshore production platform shake, serious bias current and wall stream are formed in tower, make gas-liquid contact less than, occur short circuit,
Influence desulfurization and decarburization effect.
Structure composition in general absorption tower include a set of slot type gas and liquid collecting distributor and slotted disc type gas and liquid collecting again
Distributor, and slotted disc type gas and liquid collecting redistributor is mounted on the bottom of tower.Under this shaking operating condition, slotted disc type gas-liquid is received
Collection redistributor has fatal defect.Be primarily due to: when slotted disc type gas and liquid collecting redistributor works, liquid is uniformly to divide
Cloth is on slotted disc type gas and liquid collecting redistributor, the overflow hole under conventional design, on slotted disc type gas and liquid collecting redistributor
Generally it is higher by supporting plane 50mm, liquid layer when work on slotted disk can be higher by overflow hole certain distance, it is capable of forming pressure in this way,
Make liquid that there is power to flow out by overflow hole, only holding liquid level degree, just can guarantee the discharge phase of each overflow hole
Together.When biggish shaking occurs in tower, it cannot guarantee the levelness of liquid level on distributor, make the flow between each overflow hole
There is deviation, influences to be uniformly distributed.
It can be seen that in the case where shaking, in tower slotted disc type gas and liquid collecting redistributor to the distribution of liquid not
It, is the key that reduce overall efficiency.
