Problems solved by technology

The International Maritime Organization has higher and higher standards for ship sewage discharged into the ocean, requiring the oil content of the treated sewage to be lower than 15ppm. Therefore, the ship has updated the oil-water separation equipment, but in the process of use There are still many deficiencies: on the one hand, the oil-water separation equipment performs oil-water separation on the sewage oil and water to be separated under normal pressure, and the separation effect is not good, often causing the discharged water to fail to meet the standard; on the other hand, the sewage oil separated by the oil-water separation equipment If the water content of the waste oil is too high, a larger waste oil tank should be used to store the waste oil, and the water content is too high to reduce the reuse value of the waste oil

Abstract

The invention discloses an oily water vacuum separation device. The oily water vacuum separation device comprises an oil-water separator, a dirty oil separator, a vacuum pump and a control device, wherein a water outlet for outputting sewage is positioned in the lower part of the oil-water separator and is communicated with an input port of a water pump, and an oil outlet for discharging dirty oil is positioned in the upper part of the oil-water separator and is communicated with a dirty oil input port of the dirty oil separator; a filtering element and a heater for heating to-be-separated oily water are arranged in the oil-water separator; a first extraction opening is formed in the top of the oil-water separator; a second extraction opening is formed in the top of the dirty oil separator; and the first extraction opening and the second extraction opening are communicated with an input port of the vacuum pump respectively. The oily water vacuum separation device provided by the invention separates the to-be-separated oily water and dirty oil under the vacuum condition and has a good separation effect, the oil content of the separated sewage is reduced, the water content of the separated dirty oil is reduced, disturbance and emulsification of the water pump on the oily water are reduced, and the service life of the water pump can be prolonged.

Description

technical field [0001] The invention relates to a sewage oil-water separation device, in particular to a sewage oil-water separation device in which a water pump suitable for a ship is arranged at a discharge end and adopts vacuum separation, and belongs to the field of sewage treatment equipment. Background technique [0002] A large amount of oily sewage will be produced when the ship is sailing, and the sewage will be discharged into the river or sea after being treated by the oil-water separation equipment. The International Maritime Organization has higher and higher standards for ship sewage discharged into the ocean, requiring the oil content of the treated sewage to be lower than 15ppm. Therefore, the ship has updated the oil-water separation equipment, but in the process of use There are still many deficiencies: on the one hand, the oil-water separation equipment performs oil-water separation on the sewage oil and water to be separated under normal pressure, and the...
