The specific embodiment
Further narrate the utility model below in conjunction with embodiment and accompanying drawing thereof:
The stripper of the utility model design, the sour ammonia removal that is used for the gas liquor treatment process, housing structure comprise that cat head davit 16, gas discharging opening 17, pressure tap 18, cat head charging aperture 19, random packing 20, manhole 21, foundation bolt 22, thermometer boss 23, down-flow plate 24, inspection opening 25, main charging aperture 26, still liquid outlet 27, side line extraction mouth 28, still liquid are to reboiler interface 29, reboiler return port 30, interface of the level gauge 31, drain 32.The film spray no-back mixing column plate tray structure comprises column plate 1, tower tray circle 2, downflow weir 3, connects transverse slat 4, gripper shoe 5, seal pot 6, bolt 7, nut 8, pressing plate 9, tower body 10, nozzle 11, intake chute 12, V-type deflection plate 13, air rising hole 14, reverse V-shaped gas-liquid separation plate 15, it is characterized in that the gas-liquid mass transfer unit member is a film spray no-back mixing column plate in the tower, and design has the inner concave shape seal pot, and is provided with packing section at the stripper top.Concrete technical characterictic is: the gas-liquid mass transfer unit is a film spray no-back mixing column plate on the described column plate 1, described seal pot 6 is the inner concave shape seal pot, the inner concave shape seal pot has cushioning effect to liquid flow, can reduce the fluid-tight of tower tray porch, make that the liquid levelling is steady, help the tower tray inlet region and better spray mass transfer, the number of plies of described tower tray is the 35-65 layer.
The utility model stripper is divided into two parts, and the top packing section is equipped with loose heap or structured packing, and film spray no-back mixing column plate is equipped with in plate column zone, bottom.Described film spray no-back mixing column plate is meant the patented technology (patent No.: ZL200910067917.2) that applicant Tianjin Chuangju Science and Technology Co., Ltd. is had.The concrete technical characterictic of this film spray no-back mixing column plate is: installing horizontal column plate 1 and down-flow plate 24 in tower body 10, constitute downspout between down-flow plate 24 and the tower body 10, column plate 1 is provided with rectangle air rising hole 14, and air rising hole 14 places are welded with the rectangle riser, and the upper end of riser is a nozzle 11; It is characterized in that: V-type deflection plate 13 and reverse V-shaped gas-liquid separation plate 15 are being adorned in described nozzle 11 tops, and the v-angle α of deflection plate 13 is 30 °-150 °; The v-angle α of reverse V-shaped gas-liquid separation plate 15 is 30 °-150 °, discharging intake chute 12 between two nozzles 11, and intake chute 12 intake chutes three faces have wall, an opening, dead near seal pot 6 one side seals, openend gos deep into downspout.This tower tray can avoid tower tray to stop up, and reduces liquid dispersion, significantly improves mass transfer force and tray efficiency, obviously prolongs the time between overhauls(TBO) of tower tray.
In order to satisfy the good requirement of stripper anti-clogging of gas liquor treatment process acid ammonia removal, the utility model has been done necessity or adaptive improvement, compare with normal film spray no-back mixing column plate, the percent opening of column plate 1 will be reduced between the 5-25%, and the preferred percent opening of embodiment is 8%; The height of nozzle 11 is brought up between the 50-180mm, and the nozzle height of embodiment is 90mm; The height of downflow weir 3 increases 30-50mm, is 100-130mm; The height of weir plate of embodiment is 110mm.
The further feature of the utility model stripper is, the nozzle 11 on the described film spray no-back mixing column plate is shaped as cuboid, has the slit that width is 10-50mm on the cuboid nozzle, the perhaps cylinder of a plurality of parallel arranged, and cylindrical diameter is 10-50mm; Intake chute 12 is installed between the adjacent nozzles 11, the base level of intake chute 12, the angle β between two sides is 60 °-180 °.
Traditional stripper that is used for gas liquor treatment process acid ammonia removal adopts knockout tower inner members such as bubble-cap, sieve plate, float valve, solid valve, the tower internals of this kind pattern all belongs to the bubbling quality transmission type, gas phase is a decentralized photo, liquid phase is a continuous phase, gas passes liquid layer on the plate in the mass transport process, and gas phase is comparatively disperseed, and can not effectively wash away the mass transfer unit on the column plate, solution for easy fouling often occurs stopping up the tower tray phenomenon, influences the production capacity performance of system of separation columns.The utility model is by changing the version of gas-liquid mass transfer unit in the tower, adopt film spray no-back mixing column plate for spraying quality transmission type, liquid phase is a decentralized photo, gas phase is a continuous phase, gas sprays and promotes the liquid upper punch, can effectively suppress the attachment phenomenon of solia particle in the tower tray mass transfer unit, thereby effectively avoid the generation of clogging, its operating flexibility adapts to the requirement of production more.The effect of described intake chute 12 is to reduce gradient of liquid level and backmixing of liquid phase degree, can improve the mass-transfer efficiency of tower tray, reduces veneer pressure and falls, and product quality and production efficiency are obviously promoted, can extensive use in Gas Production.After tested, when reaching same separating effect, the tower tray number of plies of the utility model knockout tower reduces 10% than the tower tray number of plies of prior art knockout tower, the little 100-200mm of the design comparable traditional design of tower diameter, and simple in structure, cost reduces.
The utility model stripper has good anti-clogging, be not only applicable to the sour ammonia removal technology of gas liquor treatment process, equally also be applicable to and easily stop up the system treatment process in the fields such as oil, natural gas, Coal Chemical Industry, be used for the predetermined substance separation or absorb operation.The utility model both had been applicable to the grassroot project design, also be applicable to the transformation of old tower, if the distance between plates of tower tray is more than 300mm, can directly change tower tray, promptly change members such as original float valve, sieve plate or bubble-cap with the film spray no-back mixing column plate tower tray, and liquid systems falls and support system constant, the applicability of industrial implementation is good.
