Detailed Description

To fully understand the function of the present application for the examiner and the person skilled in the art, the accompanying drawings and figures are described below for the preferred embodiment. Directional terms as referred to in the following examples, for example: up, down, left, right, front, rear, inner or outer, etc., are simply referred to the directions of the appended drawings. Accordingly, the directional terminology used is intended to be in the nature of words of description rather than of limitation.

Referring to fig. 1, the present application provides a dual-chamber type oil-water separator, as shown in fig. 1, comprising: an outer chamber 5 located between the upper cover 2 and the lower base 8; an inner chamber 7, located in the outer chamber 5 and not connected to the upper lid 2 and the lower bottom 8; an oil-water inlet pipe 1, the upper end of which passes through the upper cover 2 and is connected with the cooler, the lower end of which is arranged in the outer chamber 5, the opening of which is positioned below the liquid level, and the pipe wall of which is provided with a longitudinal slit 4; the lower bottom 8 is provided with a light oil pipe 6 which penetrates through the lower bottom, the upper end of the light oil pipe 6 is arranged in the outer chamber 5, the upper end of the liquid level is connected with a light oil pipe outlet valve in a downward connection mode; the lower bottom 8 is provided with a heavy oil pipe 9 which penetrates through the lower bottom, the upper end of the heavy oil pipe 9 is arranged in the outer chamber 5, an opening is arranged on the lower bottom, and a heavy oil outlet valve is connected below the upper end of the heavy oil pipe; the lower bottom 8 is provided with a return pipe 7 which passes through, the upper end of the return pipe 7 is arranged in the inner chamber 3, the upper end of the liquid level is connected with the lower end of the return pipe through a return pipe valve and is connected with an extraction tank or a concentration tank.

The working principle is as follows: extracting and separating volatile oil: the extracted or distilled cooling liquid enters the double-chamber oil-water separator through the oil-water inlet pipe 1 penetrated by the upper cover 2 and is stored in the outer chamber, the layered water enters the inner chamber 3 (a small amount of light oil enters at the beginning and then flows back to the tank body through the return pipe 7 and is distilled out again), the light oil is enriched on the liquid level of the outer chamber 5 in the outer chamber 5, the heavy oil is enriched at the bottom of the outer chamber 5 and above the lower bottom 8, the newly distilled oil-water mixture enters the outer chamber 5 through the oil-water inlet pipe gap 4 to be layered (at the moment, because of slow outflow from analysis, the stirring effect on the liquid layer in the outer chamber is small, the layering of the liquid layer is not influenced) until all the volatile oil is separated, the position of the liquid level in the double-chamber oil-water separator is adjusted by adjusting the valve connected with the lower end of the return pipe, the light oil can be discharged from the valve connected with the light oil pipe 6, and the heavy oil can be directly discharged from the valve connected with the heavy oil pipe 9, air pressure balance may be provided by the connected canister vent valve.
