The invention relates to a
pickling acid mist absorption device, which belongs to the technical field of
industrial waste gas treatment, and comprises a purification
tower, a climbing
assembly is arranged on the outer side surface of the purification
tower, a plurality of spraying pipes are sequentially arranged in the purification
tower from bottom to top, and one end of each spraying
pipe hermetically penetrates through the purification tower and then is connected with a pumping
assembly for pumping absorption liquid. An atomizing
nozzle is mounted on the spraying
pipe through a quick release
assembly; the quick release assembly comprises a first clamping ring and a second clamping ring, one end of the first clamping ring is movably connected with one end of the second clamping ring, the other end of the first clamping ring and the other end of the second clamping ring extend outwards to be provided with
butt joint plates, corresponding U-shaped clamping grooves are formed in the two
butt joint plates, screw rods are arranged in the U-shaped clamping grooves, one end of each screw rod is rotationally connected with one
butt joint plate, and the other end of each screw rod is rotationally connected with the other butt joint plate. The other end of the screw extends out of the U-shaped clamping groove and then is sleeved with a butterfly-shaped cap in a threaded mode, and the butterfly-shaped cap is locked and attached to the other butt joint plate. The disassembly and maintenance efficiency of the spray
pipe nozzle can be improved, and the safety of maintenance personnel when climbing the tower body can be improved.
