Technical Field
[0001] The utility model relates to the technical field of oil-water separation, in particular to an oil-water separation device for oily wastewater. Background Art
[0002] Oily wastewater mainly includes oilfield wastewater, wastewater from refineries and petrochemical plants, ballast water, tank washing water, engine room water of oil tankers, cleaning water of tank trucks, etc. If untreated oily wastewater is discharged at will, it will pollute the source of our daily drinking water. Once the drinking water source is polluted, it will not only infect people with diseases, but may even cause food poisoning. Therefore, it is necessary to perform oil-water separation operations on the oily wastewater.
[0003] However, the structure of the existing oil-water separation device for oily wastewater is too simple. After the oil and water are separated by the separation device, the separated wastewater is mostly discharged directly, and the wastewater cannot be recycled. As a result, a large amount of water is needed to clean the filter screen and the interior of the separation device in the later stage, resulting in a waste of water resources. Secondly, the oily wastewater contains a certain amount of impurities, and the existing separation device is unable to remove the impurities, resulting in the impurities contained in the oil and water entering the separation device and being deposited at the bottom of the separation device, causing the separation device to be blocked and inconvenient to clean. In view of the above problems, the inventor proposes an oil-water separation device for oily wastewater to solve the above problems. Utility Model Content
