Problems solved by technology

At present, the primary treatment method of gravity separation is used, which uses the density difference between oil and water and the incompatibility of oil and water to separate oil droplets, suspended solids and water in a static or flowing state, but the treatment efficiency of this method is low

Abstract

The invention belongs to the technical field of separation equipment and relates to an oil-water separation device. The main body of the oil-water separation device comprises an enclosed first tank, the top of the first tank is provided with an oil-water mixture inlet, several separator plates are arranged in the first tank and divides the first tank into several compartments, a liquid transport pipe is arranged between each two adjacent compartments and is used for communicating the two compartments. An output pipe communicated with the external environment is arranged in the last compartment. Inlets of the liquid transport pipes and the output pipe are close to the bottoms of the compartments. Outlets of the liquid transport pipes and the output pipe are close to the top of the first tank. The first compartment communicated with the oil-water mixture inlet is provided with a first oil outlet for oil discharge. The opening height of the first oil outlet is larger than the inlet height of the liquid transport pipe in the first compartment. The oil-water separation device has a simple design, a low cost, good oil-water separation effects and high efficiency, is convenient for waste oil centralized recovery and water recovery and recycle, and can be operated conveniently and fast. The oil-water separation device realizes zero discharge of COD in water.

Description

technical field [0001] The invention belongs to the technical field of separation equipment, in particular to an oil-water separation device. Background technique [0002] The urea production plant is equipped with multiple reciprocating compressors and reciprocating plunger pumps. The operation of these equipment requires a lot of oil lubrication and water cooling, and a small part of oil and water leakage is inevitable, which will cause a lot of mixing. Water with oil droplets is produced, which poses a great threat to environmental protection, and must find a way to deal with it. [0003] Taking the compressor as an example, due to the need of oil injection and lubrication during the operation of the compressor, a part of the waste oil and water will be cooled out after compression and cooling between the stages, and this part of the waste oil and water needs to be separated for the compression of the lower stage. The purpose of the final separator is to separate the liq...
