Nozzle for chemical absorption tower

The utility model relates to the technical field of tail gas absorption, in particular to a nozzle for a chemical absorption tower. The nozzle comprises an upper nozzle part and a lower nozzle part, wherein the lower nozzle part is positioned below the upper nozzle part and is connected with the upper nozzle part; a plurality of liquid spraying holes are formed in the circumferential direction of the outer surface of the lower nozzle part. Spraying liquid can be transversely sprayed through the liquid spraying holes in the lower nozzle part, the spraying liquid which is transversely sprayed cools and absorbs high-temperature fume and directly and accurately acts on a sealing washer connected to a tower section, the sealing washer can be cooled without the increase of the height of the nozzle, the problem that the sealing washer is exposed in high-temperature gas due to the cooling dead angle of the conventional spiral sprayer is effectively avoided, namely the problem of incomplete and non-ideal cooling caused by the own structure of the conventional spiral nozzle is well solved by transverse spraying, the high-temperature deformation and the ageing of the washer are delayed, the service life is prolonged, and the replacement period is shortened.
