Oil-water separation tank

Abstract

The invention provides an oil-water separation tank. The oil-water separation tank comprises an oil tank, a condensation coiled pipe, a heating coiled pipe, an emptying valve, a feeding hole, a discharging hole, sight glass and a water shearing opening, wherein the oil tank is divided into three parts, namely a heating region, a condensation region and an observation region; the oil tank is divided into inner and outer layers; the inner layer is a sealed space when the emptying valve, the feeding hole, the discharging hole and the water shearing opening are closed; the condensation coiled pipe is wound in an outer layer cavity at the top end of the oil tank to form a condensation region; the heating coiled pipe is wound in an outer layer cavity at the bottom end of the oil tank to form a heating region; the feeding hole is formed in the upper half part of the right side of the oil tank and the discharging hole is formed in the lower half part of the left side of the oil tank; the water shearing opening is formed in the bottom end of the oil tank; the emptying valve is mounted at the upper half part of the left side of the oil tank; and the surface of the tank wall of the condensation region is coated by a smooth coating so that oil drops can slide off. According to the oil-water separation tank, a simple and efficient method for improving the temperature of liquid is adopted and the density difference of an oil phase and a water phase is changed so that the oil and the water can be rapidly separated, so that the oil-water separation time is shortened, and furthermore, the good separation effect is realized; and most importantly, the problem that the oil and the water cannot be separated in winter is solved, the production efficiency is improved and the loss of crude oil can be reduced, so that the production cost is reduced.

Description

technical field [0001] The invention relates to an oil-water separation product, in particular to an oil-water separation tank. Background technique [0002] The existing technology is not aimed at the separation of carbon nine and water, because the density of carbon nine is relatively high, which is close to the density of water, so the oil-water two-phase separation time is long, and the oil-water mixture is very easy to form an emulsion interface layer, which makes the oil-water The separation effect is poor, even after a long period of standing, the oil and water phases cannot be separated well. Especially when the temperature is below zero, the small water droplets condense into small ice slags and are suspended in the carbon nine, and the gravity settling has no effect.

Problems solved by technology

[0003] The present invention mainly aims at the above problems, and provides a simple and effective method for increasing the temperature of the liquid, changing the density difference between the oil and water, so that the oil and water can be separated quickly, thereby shortening the oil and water separation time, and achieving a better separation effect. The most important thing is to solve the problem that oil and water cannot be separated in winter, improve production efficiency and reduce the loss of raw material oil, thereby reducing the production cost of the separation tank. The technical scheme is as follows:
