Described oil eliminator 4 rear end is provided with oil slick purger 6, recirculation water outlet 7 and oil eliminator inlet pipe 8; The bottom of described oil eliminator 4 is provided with wastewater discharge pipe 9; Described oil slick purger 9 is for discharging oil slick floating above remained ammonia, and described waste water purger 9 is for discharging waste water; After the remained ammonia after process is discharged from oil eliminator 4, in order to balance the air pressure in oil eliminator 4, so that the smooth discharge of remained ammonia, the upper rear end of described oil eliminator 4 is also provided with oil eliminator inlet pipe 8, described oil eliminator inlet pipe 8 is inner and external communication by oil eliminator 4, so that extraneous air can enter in oil eliminator 4 in time.The top of described oil eliminator 4 is also provided with inspection port 10, and described inspection port 10 is convenient to observation to oil eliminator 4 inside and maintenance.
Described jet-pump 1 is provided with jet-pump water inlet pipe 16, jet-pump inlet pipe 17 and jet-pump escape pipe 18, and described jet-pump water inlet pipe 16 exports 7 UNICOMs with described recirculation water, that is, small part waste water enters jet-pump 1 by jet-pump water inlet pipe 17; Jet-pump 1 utilizes mode of jet by absorption of air in water system by jet-pump inlet pipe 16, forms dissolved air water; Described dissolved air water enters molten air chamber 2 by described jet-pump escape pipe 18;
Described molten air chamber 2 comprises aerating regulation device 19, described aerating regulation device 19 is arranged at the top of molten air chamber 2, described aerating regulation device 19 comprises aerating regulation device inlet pipe 20 and aerating regulation device escape pipe, described aerating regulation device 19 is by molten air chamber 2 UNICOM of aerating regulation device inlet pipe 20 with described bottom, oil eliminator 4 UNICOM on described aerating regulation device escape pipe and described top, the upper end of described aerating regulation device escape pipe is provided with release head 21; Dissolved air water in described molten air chamber 2 enters aerating regulation device 19 by aerating regulation device inlet pipe 20, then by the release head 21 on aerating regulation device escape pipe top, bubble is discharged in oil eliminator 4, the micro-bubble that release head 21 discharges enters in remained ammonia, and bubble will adhere to entering wet goods levitated object in remained ammonia; The bubble diameter discharged by release head 21 is less, stronger to the adhesive capacity of the wet goods levitated object in remained ammonia, due to bubble adhesion after the overall proportion of wet goods suspended substance will be less than the density of liquid, according to law of buoyancy, therefore, oil and other suspended substance, by emersion liquid level, float on the upper surface of liquid.
The upper end of described molten air chamber 2 body is provided with venting port 11, and when the pressure in molten air chamber is too high, venting port 11 is for discharging unnecessary gas, and the bottom of described molten air chamber 2 is also provided with sewage draining exit 12, and described sewage draining exit 12 is for discharging waste water in molten air chamber 2.
Under normal circumstances, due to the setting of flashboard 5 between waste water sparger 3 and oil eliminator 4, remained ammonia has certain gravity flow performance in oil eliminator 4, and the oil slick that in oil eliminator 4, air supporting goes out and other floating matter flow out oil eliminator 4 by the self drainage of remained ammonia itself by oil slick purger 6.But, when remained ammonia carrys out the less and instability of amount, the gravity flow performance of remained ammonia can significantly reduce, and oil slick and other floating matter of its upper surface can not be discharged in time, be deposited in remained ammonia upper surface, be unfavorable for that oil slick is separated with other floating matter from remained ammonia.
When remained ammonia gravity flow performance is not good, in order to increase the gravity flow performance of liquid, native system is also provided with blow device.Described blow device comprises source of the gas, pressurized air supervisor 13 and scavenging duct 15, and described source of the gas is air compressor pump, and the air outlet of described air compressor pump and described pressurized air are responsible for the inlet mouth UNICOM of 13; Described pressurized air supervisor 13 is entered in oil eliminator 4 by oil eliminator 4 upper front end, and is arranged at the top of oil eliminator 4; Described oil removing, the pressurized air supervisor 13 in 4 is provided with multiple pressurized air arm 14, and described pressurized air arm 14 is parallel to be uniformly distributed.The upper end of described pressurized air arm 14 arranges scavenging duct 15, and the air outlet of described scavenging duct 15 and liquid level are 30 °.If only arrange an air outlet tube mouth on blow device, the excessive undue fluctuation probably causing liquid of pressure of air-out.
Pressurized air supervisor 13 is provided with the multistage sweeping that multiple pressurized air arm 14 can realize liquid level, multistage sweeping can strengthen the flow effect of liquid level, be unlikely to again to make liquid be produced great fluctuation process owing to blowing, and cause oil slick or suspended substance again to enter in remained ammonia.In addition, only so the air outlet of scavenging duct 15 and liquid level are 30 ° install, in order to the air outlet and liquid level that prevent scavenging duct 15 angle too conference cause the undue fluctuation of liquid level, the air outlet of scavenging duct 15 and the angle of liquid level too little, the purging performance to fluid surface can be reduced.
Blow device is arranged to 4 oil eliminators, purge power to all the time the oil slick one in oil eliminator 4 unit room, the velocity of separation of top oil or suspended substance and bottom waste water can be made to accelerate, due to the timely removing of top oil slick, oil in remained ammonia also can be separated in time, reduce the oleaginousness in remained ammonia.
This system not only can be used in coking industry remained ammonia system, also may be used for petrochemical industry and food processing enterprises, and similar water quality needs inside the system of removing top light oil and suspended substance, and have construction simple, energy consumption is low, improves the feature of deoiling effect.
Except the technical characteristic described in specification sheets, be the known technology of those skilled in the art.
