Multi-baffle type oil-and-water separator

Abstract

The invention discloses a multi-baffle type oil-and-water separator. The separator comprises a tank body, a first baffle, a second baffle and an oblique baffle, wherein the interior space of the tank body is divided into a subcritical flow defoaming area, a settling separation area and a water collection area by the first baffle and the second baffle; a feed port is formed in the subcritical flow defoaming area; a subcritical flow defoaming structure is arranged below the feed port; an air outlet is formed in the settling separation area; a bottom plate is arranged at the bottom of the first battle; a separation plate is arranged at the end part of the bottom plate; clearances are respectively reserved between the first baffle and the bottom surface of the tank body, the second baffle and the top surface of the tank body, the second baffle and the bottom surface of the tank body, the separation plate and the second baffle, the separation plate and the top of the tank body, and the oblique baffle and the second baffle; the space defined by the bottom plate, the separation plate, the first baffle and the tank body forms an oil collecting tank; an oil outlet is formed in the oil collecting tank; a water outlet and a discharge port are both formed at the upper part inside the water collecting area; the discharge port is higher than the water outlet; a sewage draining port is formed in the lower part of the water collecting area. The oil-and-water separator is simple in structure and low in operation cost, can effectively restrain emulsion and realize continuous oil-and-water separation and is high in separation efficiency and good in separation effect.

Description

technical field [0001] The invention relates to a separation device, in particular to a multi-baffle type oil-water separator. Background technique [0002] Oil and water are two types of liquids that are incompatible with each other. They must be separated according to the requirements of the process or environmental protection. The oil-water separator has become a commonly used oily water treatment equipment in industry because of its easy operation and low operating cost. , It is widely used in chemical industry, oil field, refinery and other industries. Its main principle is to use the immiscibility of oil and water and the difference in density to realize the separation of light components (oil phase) and heavy components (water phase) through gravity sedimentation. [0003] For example, the Chinese patent with authorized announcement number CN201855591U and authorized announcement date of 2011.06.08 discloses an oil-water separator, including a tank body, an oil-water...
