The purpose of the utility model is: the centrifugal pre-separation dehydration of a kind of tower tray absorption tower is provided; Under not changing the effect situation of double-barrel separator in the flow process; Through the absorption tower internal structure change; Adapt to and contain the centrifugal pre-separation dehydration of the tower tray absorption tower that liquid changes in the gas, to realize that water dew point is up to standard under the multi-state.
The technical scheme that the utility model adopts is: the centrifugal pre-separation dehydration of tower tray absorption tower, comprise the absorption tower body, and it is characterized in that: absorbing tower body is the vertical barrel structure, absorbs tower body and is located on the skirt skirt and basic fixed; The gas import is fixed on the body wall of absorption tower; The gas import gets in the absorption tower body relative with central riser side arm; Central authorities' riser is fixedly on the partition panel; Partition panel is horizontally fixed in the cavity that absorbs tower body, and central riser is vertically fixed in the cavity that absorbs tower body, and central riser medullary ray and absorption tower body medullary ray are on same straight line; The lower end of central authorities' riser is over against the lower pyramid mouth of cone structure; The upper end, umbrella top of central authorities' riser is fixed with tower tray; The top and bottom of tower tray have triglycol import and triglycol outlet respectively, and triglycol import and triglycol outlet are inwardly stretched into by the absorption tower is external, and the triglycol outlet is in the lower end of tower tray; The triglycol import is in the upper end of tower tray, and spray catcher is arranged at tower tray top; The gas outlet is arranged at the top that absorbs tower body; Leakage fluid dram is arranged at the bottom absorbing tower body; The liquid level stabilizing plate that inclination is arranged in the bottom of cone structure, the upper end of liquid level stabilizing plate are fixed on the inwall that absorbs tower body.
Described skirt is imported and exported with the upper end having heaters that absorbs the tower body joint face.
Described spray catcher is the horizontal spray catcher, and horizontal spray catcher plane is vertical with absorption tower body medullary ray.
Described spray catcher is rectilinear spray catcher, and rectilinear spray catcher plane is parallel with absorption tower body medullary ray.
The beneficial effect of the utility model: the centrifugal pre-separation of the utility model tower tray dehydration absorption tower, Sweet natural gas radially get into from the gas import and absorb in the tower body, and air impingement forced steering and moving downward behind the traverse baffle carries out the gas-liquid separation first time; Gas after the separation rises to second spray catcher and captures separation, removes 99% saturation water, continue after get into tower tray, through the absorption of tower tray gas-liquid, just through after the triglycol absorption, wherein water dew point can be far below the requirement of outer gas transmission dew point; Gas continues to rise, and gets into second spray catcher, through capturing, can tackle the triglycol more than 99% in the gas, thereby reduces the triglycol loss, handles qualified Sweet natural gas and gets into outer communication system.
