Non-metal water collection and distribution device in oil field produced water treatment sedimentation tank

Abstract

The invention relates to a water collection and distribution device in an oil field produced water treatment sedimentation tank, in particular to a non-metal water collection and distribution device in the oil field produced water treatment sedimentation tank. The device comprises a sedimentation tank body, a central cylinder body, a central pipe, a low water inlet horizontal pipe, a water inlet vertical pipe, a water distribution chamber, a water collection device, a water distribution device, a high water outlet horizontal pipe, a water distribution box and a sedimentation tank outer water outlet vertical pipe, wherein the lower end of the central cylinder is fixedly arranged at the bottom of the sedimentation tank body; the upper end of the central cylinder is fixed with the lower end of the central pipe through a flange; the water distribution chamber is fixedly arranged on the lower part of the central pipe; an air pipe is fixedly arranged on the water distribution chamber; the water distribution box is fixedly arranged on the upper part of the outer side of the sedimentation tank body; and the central pipe is communicated with the water distribution box through the high water outlet horizontal pipe. The non-metal water collection and distribution device in the oil field produced water treatment sedimentation tank has a reasonable and compact structure, is convenient to use and can effectively prolong the service life of a water collection pipe and a water distribution pipe so as to reduce the using cost and the maintenance and replacement cost of the water collectionpipe and the water distribution pipe.

Description

technical field [0001] The invention relates to a settling tank water collection and distribution device for oil field produced water treatment, which is a non-metallic water collection and distribution device in a settlement tank for oil field produced water treatment. Background technique [0002] In the process of oilfield produced water treatment, the liquid level in the settling tank always fluctuates up and down, so that the water collecting pipes and water distribution pipes in the oilfield produced water treatment settling tank are in a highly corrosive and humid environment, which is very easy to cause The water collection pipes and water distribution pipes are corroded, and the service life of the water collection pipes and water distribution pipes is much shorter than that of the settlement tank, often less than 5 years. Since the water collection pipes and water distribution pipes are inside the settlement tank, it is time-consuming and laborious to replace the wa...
