Multi-phase flow assembly type sealing coalescence oil removing apparatus

Abstract

The invention relates to a multi-phase flow assembly type sealing coalescence oil removing apparatus, which is applicable for treatments of conventional oilfield wastewater and wastewater with low polymer concentration, and comprises a tank, a water distribution chamber, coalescence sections, a separation section, a rectification section, a water collection chamber, a mud washing system, a mud discharging system, an oil collection system and the like. Wastewater enters a water distribution section inside the tank from a water inlet pipe of the multi-phase flow assembly type sealing coalescence oil removing apparatus, and then sequentially enters the first stage coalescence section, the second stage coalescence section and the third stage coalescence section, wherein each coalescing section is filled with a coalescence filler. Effluent from the coalescence section enters the separation section, wherein the separation section is filled with oblique plates having adjustable intervals. Effluent from the separation section enters the rectification section, and then enters the water collection section, wherein the rectification section and the water collection section are separated through a baffle, and the water collection section is provided with a water outlet pipe. One end of the water outlet pipe is provided with a water collection bell mouth, wherein the water is discharged out of the multi-phase flow assembly type sealing coalescence oil removing apparatus from a water outlet through the water collection bell mouth. The apparatus has the following advantages that: oil removing efficiency is high, effluent quality is good, occupation area is small, structure design is compact, automatic control is easily achieved, inner components adopt assembly type structures, and disassembly and maintenance are easy.

Description

technical field [0001] The invention relates to a purification device for oilfield conventional sewage and low-polymer sewage that integrates coalescence and inclined plate separation processes, specifically a multi-phase oil removal technology that integrates coalescence degreasing, inclined plate settling degreasing and suspended solids technology Flow-assembled closed coalescing degreasing device is suitable for the purification treatment of conventional sewage and low-polymer sewage in the process of oilfield production and development. Background technique [0002] The present invention is developed to solve many problems such as aeration of water out of a large tank of a sewage station, difficulty in collecting oil, poor sludge discharge effect, large tank body, long residence time, and low treatment efficiency. The purpose is to further improve the efficiency of conventional sewage. and low poly-containing sewage treatment efficiency, improve the treatment effect, and...
