Problems solved by technology

[0002] Due to the long running time of the air separation unit and its units, the equipment aging phenomenon is relatively serious
In particular, the corrosion of the cooler of the unit increases the number of internal leakage points, and the oil leakage of the oil system directly leads to the increase of floating oil in the return pool. If the cooling water with oil is in direct contact with the oxygen equipment, it will cause serious harm to the equipment and personnel.

Embodiment 1

[0010] A kind of circulating water degreasing device provided in this embodiment has a structure such as figure 1 As shown, it includes a fiber bundle filter 2 connected to a sewage tank 1, and fiber ball filler is filled in the fiber bundle filter. Because the existing fiber bundle filter does not have the characteristics of filtering oil, fiber ball packing is installed inside the filter, the circulating water is filtered to remove oil, and the backwash pipeline 3 is used to dilute the sodium carbonate regularly to clean the inside The fibers are degreased and cleaned, and then discharged from the sewage outlet 4 to ensure that they can be recycled. At present, the oil removal effect is relatively obvious, and the oil content in the pool meets the air separation operation standard, eliminating the hidden danger of the air separation unit.

Abstract

The invention relates to a device for removing oil from circulating water. The device comprises a fiber bundle filter, wherein a filter ball packing is filled into the fiber beam filter. According to the device, internal modification is performed inside by using the conventional equipment for removing and filtering oil from circulating water, and necessary maintenance is performed on the equipment, so that the situation of excessively high oil content in circulating water is eliminated, and great potential safety hazard of oxygen equipment during running is eliminated.

Description

technical field [0001] The invention relates to a circulating water oil removal device, in particular to a device for eliminating oil floating in the circulating water of an air separation plant. Background technique [0002] Due to the long running time of the air separation unit and its units, the equipment aging phenomenon is relatively serious. In particular, the corrosion of the cooler of the unit increases the number of internal leakage points, and the oil leakage of the oil system directly leads to the increase of floating oil in the return pool. If the cooling water with oil is in direct contact with the oxygen equipment, it will cause serious harm to the equipment and personnel. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a circulating water degreasing device to remove oil slicks in circulating water and ensure that equipment and personnel will not be da...
