The utility model discloses a
sedimentation type cooling water purification
system which comprises two
sedimentation tanks arranged in an outer frame side by side, water collecting tank steel is fixed at the tops of inner cavities of the
sedimentation tanks, water outlet pipes are fixedly communicated with the positions, corresponding to the water collecting tank steel, of the outer walls of the sedimentation tanks, and
sludge discharge pipes are fixedly communicated with the bottom ends of the sedimentation tanks. And the
tail end of the
sludge discharge pipe is communicated with an
external drainage trench. The utility model relates to the technical field of
centrifugal pump cooling and purifying equipment. According to the utility model, high-temperature water is subjected to regular standing and laminar slow release in the sedimentation tank, so that fine impurities such as
rust,
silt and suspended matters entrained in a
system can be effectively settled, the impurities are prevented from directly entering a bearing and a sealed
cooling chamber, the quality of cooling water is improved, and the problem of excessive dependence on a filter in the original scheme is avoided; the content of impurities before entering a filtering pipeline is reduced in a
precipitation pretreatment manner, so that the blocking frequency of a filter screen is reduced from the source, and the maintenance cost is reduced.
