Normal-temperature normal-pressure agglomeration type efficient oil-water separating device

Abstract

The invention discloses a normal-temperature normal-pressure agglomeration type efficient oil-water separating device which comprises an outer shell, a water inlet pipe, a water outlet pipe, an oil storage cavity, a first bin, a second bin, a third bin, a fourth bin and a fifth bin. The first bin, the second bin, the third bin, the fourth bin and the fifth bin are fixed into the outer shell side by side. A first cyclone is arranged in the first bin. The first bin is communicated with the second bin through a first guide pipe. A second cyclone is arranged in the second bin. A plurality of parallel plates are obliquely arranged on the side wall of the third bin. The parallel plates are parallel, and a gap exists between every two adjacent parallel plates. An adsorption device filled with anagglomeration medium is arranged in the fourth bin. The oil storage cavity is formed between the shell and the bins. The oil-water separating device is high in processing efficiency, good in oil-waterseparating effect and low in cost.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, and more specifically relates to a coagulation type high-efficiency oil-water separation device at normal temperature and pressure. Background technique [0002] The wastewater produced by oil fields and refineries contains oil pollution, and the wastewater with oil pollution needs to be separated from oil and water before the wastewater is discharged. [0003] At present, the commonly used physical methods of oil-water separation mainly adopt technologies such as high pressure, oxygen explosion, and membrane separation. The cost of high pressure and oxygen explosion method is relatively high, and the high pressure has high requirements on pressurized equipment and pressure vessels, the daily maintenance cost is high, and the service life is short. In the membrane separation method, the oil droplets in the oily sewage are in a viscous state, which can easily block the membrane...

AI Technical Summary

Problems solved by technology

Due to the viscous state of the oil droplets in the oily sewage, the membrane separation method is easy to block the membrane cavity and cause great hindrance to the membrane cleaning, which reduces the efficiency of the membrane and increases the cost of use.
