The absorption liquid film 11 and the counterflow type gas that descend in the counterflow type gas-liquid contact passage 10 along the respective guide plates 9 while rising in the counterflow type gas-liquid contact passage 10 of the contact promoting device 8. The liquid absorption causes the first absorption reaction, and further, while rising in the absorption tower 1, gas-liquid contact is made with the absorption liquid jetted downward from the nozzle of the spray nozzle pipe 7, and the second absorption reaction occurs. The gas is discharged from the gas outlet 3. Also, gas rectification and gas-liquid contact promotion device 8
The absorption liquid that has come into gas-liquid contact with the liquid is lowered in the absorption tower 1 and is temporarily stored in the liquid storage unit 4.

効果がある。That is, the first absorption reaction in the gas rectifying and gas-liquid contact promoting device 8 for the gas to be processed is the countercurrent type gas-liquid contact path formed by the guide plates 9 which are bent in a staggered manner. Due to the countercurrent gas-liquid contact with the absorbing liquid film 11 descending along the guide plate 9 while being rectified by 10, the absorption efficiency is extremely good, and therefore the second absorption by the spray nozzle pipe 7 is Since it is possible to use a simple one, it is possible to reduce the number of the spray nozzle pipes 7 and the number of stages, and it is possible to reduce the tower height, the tower width, etc., and to reduce the size. The same effect can be obtained by using the absorption tower shown in FIG. 1 as a dust removing tower for removing dust in the gas.

Since the gas rectifying and gas-liquid contact promoting device is provided between the gas inlet part and the spray nozzle pipe, the absorbing part has two stages of the spray nozzle pipe and the gas rectifying and gas-liquid contact promoting device. Since the gas rectifying and gas-liquid contact promoting device has a large number of countercurrent gas-liquid contact passages formed in parallel between a large number of guide plates, the gas to be treated that has flowed into the tower from the gas inlet portion is treated. The gas becomes countercurrent gas-liquid contact with the absorbing liquid film that descends along the guide plate while being rectified in the gas-liquid contact path, and the absorption efficiency becomes extremely good. Since it is simple, the number of spray nozzle tubes and the number of stages can be reduced, and the tower height, tower width, etc. can be reduced to achieve miniaturization. Alternatively, the absorption reaction can be easily increased without increasing the size of the absorption tower.
