The technical scheme that the utility model adopts is: the centrifugal mist formula pre-separation dehydration absorption tower of vertically catching, and it is characterized in that: comprise the absorption tower body, absorbing tower body is the vertical barrel structure, absorbs tower body and is located on the skirt skirt and basic fixed; Gas import 3 is fixed on the sidewall that absorbs tower body and vertically stretches into and absorbs in the tower body; The inner of gas import is relative with central riser outer arm; Central authorities' riser is fixed through 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; In central riser lower end cone structure is arranged, the lower end of central riser is over against the lower pyramid mouth of cone structure, and the upper end of central riser is a umbrella shape; Central authorities riser top is fixed with filler; There are triglycol import and triglycol outlet in the top and bottom of filler, 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 filler; The triglycol import is in the upper end of filler, and spray catcher is arranged at filler top; Described spray catcher is a vertical stratification, and spray catcher is parallel with absorption tower body medullary ray; The gas outlet is arranged at the top that absorbs tower body; Leakage fluid dram is arranged at the bottom absorbing tower body; In the bottom of cone structure and absorbing the liquid level stabilizing plate that is fixed with inclination on the tower body inwall.
Described skirt and upper end that absorbs the tower body joint face and having heaters import and export on the lower end outer wall that absorbs tower body.
The beneficial effect of the utility model: the utility model is centrifugal vertically catches mist formula pre-separation dehydration absorption tower, and Sweet natural gas radially gets into from the gas import and absorbs 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 filler, through the absorption of filler 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.
