Tube sheet, is arranged on tower body upper cover position, for installing cyclone pipe; Tube sheet and cyclone pipe are for removably connecting;
Manhole, is arranged on tower body corresponding to breach;
Cyclone pipe, has many, and its upper end is connected on tube sheet, and the upper port of cyclone pipe is stretched out tube sheet and exposed; The lower port of cyclone pipe is positioned at the top of fluid-tight dish.
Mozzle, is arranged on described fluid-tight dish, for the hydrops above fluid-tight dish being imported to the seal pot of column plate; The outlet of mozzle is positioned at the below of fluid-tight dish and the seal pot of subtend column plate; The entrance of mozzle is positioned at the top of fluid-tight dish, and the entrance of mozzle is higher than the outlet of described cyclone pipe.
Preferably, described breach can be " U " shape structure.
Described mozzle has two.Also other quantity can be selected according to the caliber of flooding velocity and overflow pipe.
The mode of removably connecting of water conservancy diversion tube hydroforming has multiple, and preferably, described cyclone pipe can for being threaded with described tube sheet.This structure installment, dismounting all very convenient.
Compared with prior art, absorption tower provided by the utility model structure, cyclone is applied to absorption tower tower top, traditional wire mesh demister is substituted as internals, gas-liquid separator is effective, effectively prevent entrainment, reaches more than 90% to the drop removal efficiency of more than 15 μm, greatly reduce the loss of absorbing liquid, reduce the energy consumption of circulator to a certain extent; When not increasing tower height, not increasing existing equipment investment, save separation container housing, equipment investment and a floor space.The design of demountable structure between cyclone pipe and tube sheet, facilitates dismounting and the installation of cyclone pipe, is convenient to checking maintenance.
The utility model is especially suitable as top gaseous phase entrainment absorption tower and uses, or directly improves existing absorption tower.

Fig. 2 is the sectional view along A-A line in Fig. 1;
Fig. 3 is the sectional view along B-B line in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, this absorption tower comprises:
Tower body 1, is provided with column plate 12 in tower body 1, the top of tower body 1 is provided with gaseous phase outlet 11.In tower body and tower tower plate structure can select as required of the prior art any one.The technical scheme of the present embodiment can directly apply to the transformation on existing absorption tower.The top of tower body is provided with absorbing liquid entrance 14.
Fluid-tight dish 2, is fixed in tower body, to be positioned at above column plate and below absorbing liquid entrance.Fluid-tight dish 2 is provided with breach 21, for entering in tower body 1 from this breach for maintainer.
Tube sheet 3, is arranged on tower body upper cover position, for installing cyclone pipe 5.Tube sheet and cyclone pipe 5 are for removably connecting, and the present embodiment is for being threaded.
Manhole 4, is arranged on tower body 1 corresponding to breach 21, for from then on entering in tower body 1 for checking maintenance personnel.
Cyclone pipe 5, has many, and its upper end is connected on tube sheet 3, and the upper port of cyclone pipe 5 is stretched out tube sheet 3 and exposed; The lower port of cyclone pipe is positioned at the top of fluid-tight dish 2.
Mozzle 6, is fixed on fluid-tight dish 2, for the hydrops above fluid-tight dish 2 being imported to the seal pot 13 of column plate.The outlet of mozzle 6 is positioned at the below of fluid-tight dish 2 and the seal pot 13 of subtend column plate; The entrance of mozzle 6 is positioned at the top of fluid-tight dish 2, and the entrance of mozzle 6 is positioned at the exit position higher than cyclone pipe 5.The height that mozzle 6 exceeds fluid-tight dish 2 is height liquid seal.
This absorption tower is applied to 500,000 tons/year of catalytic gasoline selective hydrodesulfurization devices, as desulphurization of recycle hydrogen tower, its operation principle is described below:
From desulphurization of recycle hydrogen column overhead first block of column plate recycle hydrogen out, tangentially enter cyclone pipe, the microlayer model carried secretly of recycle hydrogen accelerates to rotate along the helical of cyclone pipe, helical is rotate downward runner, drop also moves downward along helical while rotation, be separated with recycle hydrogen, microlayer model collects the large drop of formation gradually, discharges from the lower nozzle of cyclone pipe.Recycle hydrogen under the promotion of pressure differential, from the discharge suitable for reading of cyclone pipe.Discharge via gaseous phase outlet.Lean solvent to enter in tower body above fluid-tight dish from absorbing liquid entrance, rests on fluid-tight dish, forms effective fluid-tight to cyclone pipe, when hydrops reach a certain height, overflowed on the seal pot of ground floor column plate by mozzle.
This absorption tower structure can effectively be separated liquefied ammonia and recycle hydrogen, and compared to prior art, the loss of amine liquid reduces 64%, and recycle hydrogen molecular weight reduces by 0.8; The MDEA content of device outlet be less than 10 micrograms/gram, finally achieve being separated of gas and liquid or gas and solid, can more than 90% be reached to the drop removal efficiency of more than 15 μm, meet production technology completely to the requirement of recycle hydrogen amine liquid entrainment.
