Abstract
The utility model discloses an ammonic washing tower, which is provided with a coal gas inlet (9) at the bottom and a coal gas outlet (1) on the top. The tower internals are a liquid distributing device (4) and an accumulatory (8), the tower is filled with metal perforated plate corrugated filler (6), which is packed in three layers. The filler in each filler (6) layer is arranged crisscrossly and vertically. The filler (6) layer is provided with a liquid distributing device (4) on the top and a liquid accumulatory (8) at the bottom. The filler of the ammonic washing tower of the utility model is metal perforated plate corrugated filler, and the surface area of the corrugated board is large, increasing gas-liquid contacting area, improving ammonic washing purification efficiency, saving energy, and reducing pollution.
Description
Technical field:
The utility model relates to a kind of industrial separation equipment, especially is applied to the washing tower equipment of industries such as oil, chemical industry, pharmacy.
Background technology:
The purification process of coke-oven gas is: the raw gas that comes out from coke oven through the primary cooler cooling after, be sent to washing by gas blower, through wash naphthalene, wash ammonia, wash the benzene purifying treatment after the qualified coal gas of gained be sent to the user.Wherein washing ammonia water in Ammonic washing tower carries out as dissolve medium, washing ammonia at present usually will be through empty spray Ammonic washing tower and the washing of wood grid packing Ammonic washing tower two-stage, just can obtain qualified coal gas, no any filler in the tower of empty spray tower, the coal gas that needs to purify at first enters empty spray tower, for the ammonia effect and the amount of conserving water are washed in raising, empty spray tower is established three sections water cycles, and every section water cycle carries upper and lower water lines.Coal gas enters from the bottom of tower, and makes progress away by gas flue, and coal gas is in up process, and with the reverse contact of water of spraying downwards, flush away part ammonia comes out from cat head, enters wooden lattice Ammonic washing tower then.Wood lattice Ammonic washing tower is the washing tower that is filled with wood grid packing in the tower, and wood grid packing is the grid of forming with batten, every layer of staggered arranged vertical of filler.The coal gas that comes out from sky spray tower enters wooden lattice Ammonic washing tower by the wood grid packing tower bottom,, reaches and further washes the purpose that ammonia purifies with the top reverse contact of water of being sprayed by spiral nozzle through the wood grid packing layer.Purify good coal gas and come out to enter next process from cat head.
Wash in the ammonia equipment above-mentioned, the shower nozzle of empty spray tower stops up easily, power consumption is big, and wood grid packing is easily stopped up, cleaned trouble by tar, naphthalene and incrustation scale, and the whole ammonia system purification efficiency of washing is low, and coal gas contains ammonia and often surpasses 0.1g/m behind the tower
3, because of surpassing 0.05g/m
3Standard and defective, system's running resistance is big, not only influence coal gas and carry, and the working cost height, power consumption is big, water consumption is big, stops the tower cleaning often, influences continuous production.In addition, because the pond of opening wide is many, pollute also serious.
The utility model content:
The purpose of this utility model is at above-mentioned defective, provides a kind of can the raising to wash the ammonia purification efficiency, saves the energy, reduces the Ammonic washing tower that pollutes.
The utility model Ammonic washing tower bottom is provided with gas entry, top of tower is provided with gas exit, column internals is liquid distributor and collector, filler metal perforated plate corrugated filler in the tower, filler divides three layers of filling, the staggered arranged vertical of filler in each packing layer is provided with liquid distributor above packing layer, the below is provided with liquid header.
As a kind of improvement of the present utility model, ripple packing plate percentage of open area is 10%.
As another improvement of the present utility model, liquid distributor is a narrow slot type, and major trough links to each other with groove is vertical, props up uniform spray hole on the groove, and be provided with mudhole on groove.
As another kind of improvement the of the present utility model, the supportive grid of liquid header is provided with some liquid collecting plates that are arranged in parallel, and is provided with coal gas air duct and collector tube, liquid downtake below the liquid collecting plate.
The utility model Ammonic washing tower filler is a metallurgic orifice corrugated packing, and the waved plate surface-area is big, has increased the gas-to-liquid contact area, improves and washes the ammonia purification efficiency.The waved plate upper punch has aperture, and aperture has increased the upwards horizontal mixing of mobile gas on the one hand, can make liquid at aperture punishment stream on the other hand, impels liquid distribution more even.Also the microgroove that rolls can be arranged on the plate, make liquid good, on plate, form liquid film as thin as a wafer, also can increase duration of contact and area, improve and wash the ammonia purification efficiency the wet performance of filling surface.The utility model has been considered to improve and has been washed ammonia efficient, and spray liquid must be evenly distributed, and has adopted the sparger of narrow slot type structure, and gas-to-liquid contact is all right in the tower, and detersive efficiency improves, and liquid header helps reducing the resistance of gas-liquid by bed.

Embodiment:
As shown in Figure 1, the utility model Ammonic washing tower, tower bottom is gas entry 9 and ammoniacal liquor water outlet 10, top of tower is gas exit 1 and catches mist layer 2, water 3 enters Ammonic washing tower from the liquid inlet, flows downward from liquid distributor 4, and there is filler pressing 5 top of packing section 6, the below is that filler back up pad 7,8 is a liquid header.Filler metal perforated plate corrugated filler 6 in the tower, metallurgic orifice corrugated packing 6 is the JKB-125Y type, and thick about 0.2 millimeter, can there be the microgroove that rolls on the surface, and considers the corrodibility of washing liq, and the ripple packing plate adopts stainless steel.Ripple packing 6 upper punches have aperture, percentage of open area 10%, and percentage of open area is excessive, can influence washing effect, and too small then pore volume easily stops up.Corrugated plate packing two to three sections fillings in 6 fens, packed height is relevant with tower diameter, Ammonic washing tower tower diameter 3500mm shown in Figure 1, full tower packing divides three layers of filling, every floor height 7200mm, liquid distributor 4 is three, liquid header 8 is two, as Fig. 2, shown in Figure 3, liquid distributor 4 is the narrow slot type structure, about major trough 41 wide 200mm, about groove 42 a wide 60mm, prop up the spray hole of uniform diameter 3.8mm on the groove 42, also be provided with mudhole on the groove.As Fig. 4, shown in Figure 5, collector 8 supportive grid 82 upper supports many liquid collecting plates that are arranged in parallel 81, liquid enters collector tube 83 by each edge, liquid collecting plate 81 two ends, and from the liquid downtake 84 influent spargers 4 of collector 8 belows, coal gas is upwards flowed by air duct 85 again.
For preventing that Ammonic washing tower from stopping up, bath water is the softening water through removal calcium, magnesium ion.
Operating process of the present utility model can be summarized as: bath water is sent into the liquid distributor of the superiors from the tower upper entrance, wait to wash coal gas and enter Ammonic washing tower from the tower bottom gas inlet, upwards flow by liquid header, make progress away through the slit between filler again, contact with the water that gets off from liquid distributor is reverse, ammonia stripping in the coal gas is got off, reach the purification purpose.Collected rich ammoniacal liquor after the washing flows out from the outlet of tower bottom.
The utility model uses in the φ 3500mm of Xingtai Steel ﹠ Iron Co Ltd Ammonic washing tower, handles coal gas amount 42000mm
3/ h, purification efficiency is: contain ammonia 7.5g/m in the inlet gas
3, contain ammonia＜0.05g/m in working off one's feeling vent one's spleen
