Recycling tower middle section utilizes a metal槽盘式 distributorIt consists of a rectangular riser tube, angle iron, channel iron guide fluid tubes, dovetail or channel iron liquid stoppers, flat plates, support rings, and support beams. The main difference from the disc-type liquid distributor is that two rows of small holes, larger at the top and smaller at the bottom, are respectively located at the top, middle, or middle-bottom of the rectangular riser tube. The differently sized holes on the same vertical line are covered by angle iron or channel iron guide fluid tubes.

Central section of the recovery tower uses a metal槽盘式distributorThe diameter deviation of the spray holes on the upper and lower layers of the riser pipe should be strictly controlled during manufacturing, with the edges being smooth. Meanwhile, the distributor should be installed to ensure that both the upper and lower spray holes are on the same horizontal plane. The horizontal deviation between any two spray holes on the same layer should not exceed 3mm. The rest of the technical requirements should be manufactured and inspected according to JB1205 "Technical Conditions for Tower Trays" and the standard manufacturing drawings.
