The invention discloses a chemical saturated liquid solute trapping pipeline system which comprises a main pipeline. At least one sedimentation pipe with an upper opening and a lower opening is arranged below the main pipeline along a through-flow direction, the upper openings are formed in the bottom surface of the main pipeline, the side, which is positioned at the tail end of the through-flow direction of the main pipeline, of each upper opening is higher than the side, which is positioned in an initial end of the through-flow direction of the main pipeline, and the through-flow direction is level with the ground. The chemical saturated liquid solute trapping pipeline system has the advantages that saturated solution can flow along the through-flow direction, tiny solute particles can crash onto the pipe walls of the sedimentation pipes when the saturated solution flows through the upper openings, and can be fed into the sedimentation pipes, and accordingly effects of trapping the solute particles can be realized by the chemical saturated liquid solute trapping pipeline system; the chemical saturated liquid solute trapping pipeline system is used for improving the production efficiency.
