Abstract

The invention discloses a top-reduced oil-water separation device which comprises a horizontal cylinder, a vertical cylinder, an electrostatic coalescence unit and a transformer, a weir plate is vertically arranged on the right side in the horizontal cylinder, the vertical cylinder is vertically inserted into the left side of the horizontal cylinder, and the electrostatic coalescence unit is located in the horizontal cylinder between the vertical cylinder and the weir plate. The electrostatic coalescence unit comprises a plurality of electrode plates arranged in the vertical direction, the electrode plates comprise plate electrode plates and corrugated electrode plates, the plate electrode plates and the corrugated electrode plates are alternately arranged in parallel, a flow channel is formed between each plate electrode plate and the corresponding corrugated electrode plate, and a liquid distribution component is arranged at the bottom of the vertical cylinder. An upper tube plate and a lower tube plate are sequentially and horizontally arranged in the vertical cylinder from top to bottom, a rotational flow tube is vertically and fixedly arranged on the lower tube plate, and a rotational flow exhaust tube is arranged at the top of the rotational flow tube. Three-stage separation of oil, gas and water can be realized, the separation process is greatly simplified, and intensive separation is realized.

Description

technical field [0001] The invention relates to the technical field of a vacuum tower system of an atmospheric and vacuum device in the oil refining industry, in particular to a top-reducing oil-water separation device. Background technique [0002] As oilfield exploitation gradually enters the middle and late stages, the water content of crude oil increases sharply. At the same time, the wide application of tertiary oil recovery technologies such as chemical flooding intensifies the emulsification of crude oil. The emulsification of various equipment at the top of the pressure tower is serious. At present, the top-reducing oil-water separation tank in the refinery mainly absorbs the top-reducing oil from each evacuated condenser, as well as part of the top-reducing gas and sulfur-containing sewage, and separates oil, gas, and water into three phases, and discharges them to the top-reducing oil pump respectively. , roof-reducing drainage pump and non-condensable gas skid-mo...
