Description
Technical Field
The application relates to the technical field of gas distribution modes in chlorine washing towers, in particular to a dispersive gas distribution type chlorine washing tower.
Background
In an ionic membrane caustic soda production system, a chlorine washing tower is used for cooling, dewatering and removing impurities from chlorine, and generally adopts an empty tower structure. Chlorine generated in the ionic membrane electrolysis process enters from a side wall inlet flue gas pipeline at the lower part of the chlorine washing tower, is in countercurrent contact with the spray acid in the packing layer to realize mass transfer and heat transfer, and leaves the tower through a chlorine pipeline at the top of the tower. In the chlorine gas inlet mode, the traditional scrubbing tower generally has five modes of straight pipe air inlet, straight pipe downward notch air inlet, straight pipe downward oblique opening air inlet, straight pipe downward connecting bent pipe air inlet and tower bottom upper air inlet.
Wherein, the straight tube mode structure of admitting air is simplest, and it is also comparatively general to use, but, adopts the traditional chlorine gas scrubbing tower that the tower side straight tube admits air, along with the increase of tower footpath, and gas distribution uniformity is worse. Under the same gas velocity, at the same tower section, the unevenness is larger when gas-liquid two-phase mixed feeding is compared with that of single-phase empty tower, and the end effect that the gas quantity in the center area of the tower is more and the gas quantity in the wall area of the annular tower is less exists, so that the efficiency of the washing tower is reduced. Analyzing the reason, on one hand, a large amount of liquid drops in entrainment occupy partial gas flow space, so that the regional distribution of gas is not uniform; on the other hand, the acting force between the gas-liquid interfaces also increases the local velocity gradient of the gas, and the two act together to ensure that the unevenness of the gas-liquid mixed feeding is larger than that of the single-phase feeding.
Therefore, a solution for effectively reducing the gas distribution end effect and ensuring the heat and mass transfer efficiency in the tower is needed.
