Description

The oily sludge three-phase separating device

Technical field

The utility model relates to a kind of oil-bearing sludge treatment equipment, and particularly oil, mud, water three-phase separating device in a kind of oily sludge belong to environmental protection field, oil field.

Background technology

Oil production, collection are defeated, produce a large amount of oily sludges in the smelting process, if do not handled, to cause environmental pollution and the wasting of resources, the most of oil fields of China have all entered " three height " period of high moisture, high oil recovery rate, high recovery percent of reserves at present, along with the increase of water injection rate, the oily sludge growing amount also increases thereupon.Oily sludge is because having characteristics such as oleaginousness height, mink cell focus component height, have very important hydrocarbon resources and recycle value, therefore how to realize the processing of oily sludge harmless resource utilization, reclaiming this solid waste problem of good disposal of crude oil while and receive much concern always, also is a great problem of puzzlement petroleum chemical enterprise.

The method of handling oily sludge at present both at home and abroad has biological treatment, physical mechanical facture, burning method and landfill method usually, and wherein biological treatment long processing period, and oily sludge can not get recycling; Burning method causes secondary pollution; Landfill method does not tackle the problem at its root, and fails to accomplish resource utilization, the innoxious use of oily sludge, and a large amount of oil products are wasted.

Summary of the invention

The utility model provides a kind of processing cycle short, good separating effect, the oily sludge three-phase separating device of the recyclable utilization of oil product.

Technical scheme to be solved in the utility model is: a kind of oily sludge three-phase separating device, this device comprises one-level mixing stirred pot, secondary mixing stirred pot, one-level three phase separation jar, secondary three phase separation jar, water-and-oil separator, 1# solution circulated jar, 2# solution circulated jar, wherein one-level three phase separation jar is connected with one-level mixing stirred pot, secondary mixing stirred pot is connected with one-level three phase separation jar, secondary three phase separation jar is connected with secondary mixing stirred pot, and one-level three phase separation jar is connected with water-and-oil separator respectively with secondary three phase separation jar, and, one-level three phase separation jar is connected with 1# solution circulated jar, and secondary three phase separation jar is connected with 2# solution circulated jar.

The oily sludge three-phase separating device reaches oil, water, mud three phase separation by mechanical stirring, three phase separation, modified thickening, compression mummification and oily water separation compound system.Described mechanical stirring is to utilize the mixing stirred pot that greasy filth is fully mixed with the chemical agent that promotes oil, mud to separate, mix the built-in steam heating coil of stirred pot to the heating of greasy filth slurry, temperature control is at 55 ℃-70 ℃, greasy filth is easier separation under heating status, and the oil that is attached on the mud granule parses.Described three phase separation is to utilize the three phase separation jar with oil, water, mud three phase separation, and isolated oil enters water-and-oil separator and recycle, and mud compresses drying and other treatment after modified thickening, and water enters the recycle of solution circulated jar.Described three phase separation jar built-in ultrasonic wave promotes device and mud scraper, ultrasonic wave promotes device sends ultrasonic wave and has accelerated the oil reservoir emulsion process of being stripped from, oil is separated with silt particle, and the mud that mud scraper will stick at tank skin is peeled off at the bottom of jar and is convenient to conveying.

Described mechanical stirring and three phase separation according to the actual production demand, can be that one-level links to each other also can be plural serial stages.

The beneficial effects of the utility model are: treatment effect is good, can be good at oil, mud, water three phase separation, oil is recyclable, reusable edible after the sewage disposal, can be used as greening after the compressed drying and other treatment of mud with soil, accomplished pollution-free, zero release, recycling treatment, and the utility model can the serialization operation, simple to operate, actual application value is arranged.
