Gas-liquid distributing device for large stuffing tower device

The invention is a vapor-liquid distributing device arranged in a large packing tower, comprising longitudinal bearing liquid-distributing grooves and transverse liquid-distributing grooves. The longitudinal bearing liquid-distributing grooves are provided with bearing support structures which are supported on the tower walls and are capable of sliding along the transverse direction of the tower walls, the transverse liquid-distributing grooves are provided with sliding supports and translational support structures which are supported on the longitudinal bearing liquid-distributing groove or the tower wall, the lower portion of a groove body of each liquid-distributing groove is provided with liquid distributing holes, and the longitudinal bearing liquid-distributing grooves are provided with liquid communicating pipes which respectively communicate each transverse liquid-distributing groove. The slid connecting manner is adopted between the grooves of the device and between the grooves and the tower walls, the relative place changes between structures caused by expansion and contraction are allowed, and the deformation of the structures can be effectively avoided to ensure stableoperating. Each longitudinal bearing liquid-distributing groove is bestowed with bearing function for supporting the device, and thereby the longitudinal height of the device can be obviously shortened. The invention has the outstanding advantages of deformation resistance and low longitudinal height, and the invention can be widely applied to the industry fields such as chemical industry, petrochemical industry, ethylene, oil refining and the like.
