Description
Technical field
The utility model relates to the coal-tar middle oil tripping device with ammoniacal liquor of a kind of coking ammonia water process, particularly relates to a kind of cyclone air-flotation tripping device of tar ammonia.
Background technology
In coke-oven plant's ammonia disposal system, the tar gone out by gas-liquid separator separates and ammoniacal liquor enter mechanical dreg scraping trough remove coke tar refuse, after carry out settlement separate at tar and ammonia water separation hopper.Isolated tar enters tar medial launder and is then delivered to the storage of oil depot device; An ammoniacal liquor part melts down use as cyclic ammonia water, and remained ammonia enters ammonia steaming device again after standing, ceramic filter and jet air float oil removing.Aborning, oil removal efficiency is on the low side (being generally about 60%), remained ammonia oil-containing is too high perplexs subsequent handling always, the tar carried secretly in ammoniacal liquor is easy to blocking ammonia still process e-quipment and pipe, after entering dephenolize system, influential system microorganism active, directly affects the COD index of outer draining.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of cyclone air-flotation tripping device of tar ammonia, can be directly installed in coke-oven plant's remained ammonia treatment system, the tar carried secretly be had to the tripping device of better removal effect in ammoniacal liquor.
For achieving the above object, the utility model is achieved through the following technical solutions:
A cyclone air-flotation tripping device for tar ammonia, comprises fresh feed pump, cyclone separator, oil removal by air bubbling room, jet-pump, ejector, dissolving, and before fresh feed pump is located at cyclone separator, cyclone separator is connected with oil removal by air bubbling room, realizes the second-order separation; Oil removal by air bubbling room connects jet-pump extension liquid, ejector is connected with dissolving by pipeline with jet-pump, introduce nitrogen with ejector, the partially liq that nitrogen is drawn with jet-pump is fully mixed by dissolving, after return oil removal by air bubbling room by fluid jet nozzle jet release of pressure.
Described oil removal by air bubbling room is made up of the oil removal by air bubbling room of 4 ~ 6 series connection, establishes by burst size setter, control flow between each room between each room and dissolving.
Described oil removal by air bubbling indoor arrange weir plate and liquid level regulation device.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is rational in infrastructure, and controllability is good, wide accommodation; Simply, floor space is little for the utility model structure and auxiliary facility, and treatment capacity is large, and energy consumption is low, and separation efficiency can reach more than 85%.Adopt nitrogen as source of the gas, decrease ammonia water oxygen level, dissolved air time is short, alleviates equipment corrosion.Technical process is simple, and reduce investment outlay, easy and simple to handle, operation and maintenance cost is low, effect stability.Tar ammonia cyclone air-flotation tripping device easy to clean, safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: the 4-jet-pump 5-ejector 6-dissolving of 1-fresh feed pump 2-cyclone separator 3-oil removal by air bubbling room.
Embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but it should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1, the cyclone air-flotation tripping device of tar ammonia, comprises fresh feed pump 1, cyclone separator 2, oil removal by air bubbling room 3, jet-pump 4, ejector 5, dissolving 6, before fresh feed pump 1 is located at cyclone separator 2, cyclone separator 2 is connected with oil removal by air bubbling room 3, realizes the second-order separation; Oil removal by air bubbling room 3 connects jet-pump 4 extension liquid, ejector 5 is connected with dissolving 6 by pipeline with jet-pump 4, introduce nitrogen with ejector 5, the partially liq that nitrogen is drawn with jet-pump 4 is fully mixed by dissolving 6, after return oil removal by air bubbling room 3 by fluid jet nozzle jet release of pressure.
Wherein, oil removal by air bubbling room 3 is made up of the oil removal by air bubbling room 3 of 4 ~ 6 series connection, establishes by burst size setter, control flow between each room between each room and dissolving 6.Arrange weir plate and liquid level regulation device in oil removal by air bubbling room 3, adjustment oil reservoir height, realizes whole flowing fulls of gas-floating chamber top oil reservoir.Remained ammonia mixes with nitrogen in high-pressure spray mode by jet-pump 4, is regulated entering nitrogen amount by ejector 5.The tank internal pressure of dissolving 6 remains on 0.20 ~ 0.35Mpa, adopts nitrogen as dissolving source of the gas.
During work, remained ammonia after standing separation is under the pressure effect of fresh feed pump 1, cyclone separator 2 is tangentially entered with certain original speed, the component that density is different is separated under gravitational and centrifugal forces, the tar that density is larger flows downward along taper tube wall, discharged by bottom oil outlet, the ammoniacal liquor that density is less converges in center and outer tar countercurrent flow, discharges through top overflow port.Ammoniacal liquor through a cyclonic separation carries out secondary separation to enter oil removal by air bubbling room 3 from stream mode, and oil removal by air bubbling room 3 is divided into the oil removal by air bubbling room 3 of 4 ~ 6 series connection, establishes burst size setter, control to establish flow between each room between each room and dissolving 6.Extension ammoniacal liquor bottom water side, oil removal by air bubbling room 3, introduces nitrogen with ejector 5 simultaneously, to be mixed by ammoniacal liquor and squeeze into dissolving 6 with jet-pump 4 in high-pressure spray mode with nitrogen.Tank internal pressure is remained on 0.20 ~ 0.35Mpa, the two mix further dissolving 6 in laggard enter jet oil removing room, by fluid jet nozzle jet release of pressure, warp float redistributor distribution on microbubble, be distributed in oil removal by air bubbling room 3, and in uphill process, rise to liquid level after tar adsorption and other impurity, by oil removal weir plate and liquid level regulation device, overflow in flowing full mode, realize oil removing.
The utility model is through test the utility model oil removal efficiency more than 85%, and the also impurity such as other suspended substances adsorbable simultaneously, reduces the coal-tar middle oil detrimentally affect to subsequent recovery technique of ammoniacal liquor, improve ammonia still process effect and quality product, reduce the maintenance cost of equipment.
