The specific embodiment:
In order to make creation characteristic of the present utility model, technological means and to reach purpose, be easy to understand understanding, further set forth the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1～4, a kind of water scrubber, comprise tower body 1, described tower body 1 lower end one side sets into gas port 2, tower body 1 top sets out gas port 3, and described tower body 1 inside arranges some supporting arrangements 4 and is divided into some independent washings chamber 5 by described supporting arrangement 4, and described supporting arrangement 4 comprises web plate 41 and the hold down gag 42 of stack successively, described hold down gag 42 downsides arrange liquid distribution trough 6, i.e. sprinkling equipment.The effect of described tower body is, all washed reactions all carry out in the tower body interior, and dusty gas enters water scrubber from air inlet, and after the intrinsic processing of tower, the gas that meets effluent standard flows out from gas outlet.Therefore the shape of tower body can be cylindrical shape, can be also square, can be by metal (steel, alloy or non-ferrous metal), plastics, timber, or take rubber, plastics, brick makes as the composite of internal layer or lining, described tower body inner bottom part arranges water tank 7.The opening 51 that maintenance and monitoring are provided is set on tower body corresponding to described independent washing chamber.Described tower bodies top is for going tip circle tapered.One of embodiment of described hold down gag 42 is stiffener 42, and described stiffener 42 is comprised of crisscross axle 421.Described supporting arrangement 4 is 2～5.Described sprinkling equipment comprises spraying rack 61 and is installed on the some liquid distribution devices 62 on spraying rack 61.Described tower body exterior arranges the shower 63 be connected with described spraying rack 61 respectively, and the upper-lower position of described shower 63 staggers.
Supporting arrangement 4, filler supporting device is for the filler in support tower, and supporting arrangement can be screen type, hole cast, hump type etc.
Hold down gag 42, spraying rack top are installed hold down gag can prevent that the sprinkling equipment layer occurs loosening and beats under the effect of air-flow.As embodiment, hold down gag can be pressing plate or bed confinement plate.Pressing plate freely is positioned over the packing layer upper end, by own wt, filler is compressed, and is applicable to the broken dumped packing of easy generation that pottery, graphite etc. are made.Broken dumped packing and all structured packings of difficult generation that the bed confinement plate is made for metal, plastics etc.The bed confinement plate will be fixed on Ta Bishang, is installation and the use that does not affect liquid distribution trough, can not adopt continuous tower circle to fix, and can be fixed in Ta Bi with screw for trourelle, and large tower is fixed with journal stirrup.
The disc type distributor has the forms such as disc grizzly pass distributor, disc type overflow pipe distributor.Liquid adds on distributing disc, flows down through sieve aperture or overflow pipe.The distributing disc diameter is 0.6～0.8 times of tower diameter, and this kind distributor is for the tower of D<800mm.
Pipe distributor is made by the tube having holes of different structure form.Its outstanding characteristics are simple in structure, and the free cross-section that supplied gas flows through is large, and resistance is little.But aperture easily stops up, elasticity is generally less.The tubular liquid distributor uses very extensive, multiplex in the packed tower of low middling liquid load.In rectification under vacuum and screen waviness packings tower, thus due to liquid load less commonly used it.Pipe distributor has the difformities such as calandria, annular tube type.According to the liquid load situation, can make single or double.
Tank type liquid distributor normally consists of splitter box (claim not only major trough or one-level groove), distributing slot (but also claiming secondary groove or secondary groove).The one-level groove just is divided into some stream strand by the bottom land perforate by liquid, adds respectively the liquid distributing groove of its below.The bottom land of distributing slot (or cell wall) is provided with duct (or conduit), and uniform liquid is distributed on packing layer.
Tank type liquid distributor has larger operating flexibility and the stifled property of fabulous anti-soil, is particularly suitable for large gas-liquid load and contains the separation occasion of solid suspension, liquid that viscosity is large.Because groove type distributor has good distribution performance and the stifled performance of anti-soil, range of application is very extensive.
The slotted disc type distributor is the liquid distributor of developing in recent years, and it organically integrally combines the advantage of slot type and disc type distributor, has liquid collecting, separatory and minute three kinds of effects of gas concurrently, compact conformation, and operating flexibility was up to 10: 1.Uniform gas-liquid distribution, resistance is less, is specially adapted to easily carry secretly, susceptible to plugging occasion.
When liquid collection and apparatus for redistributing, liquid flow downward along packing layer, the phenomenon that has deflection tower wall to flow, this phenomenon is called wall stream.Wall stream will cause gas-liquid skewness in packing layer, and mass-transfer efficiency is descended.For reducing the wall flow phenomenon, but the interval certain altitude arranges liquid redistribution device in packing layer.
Under normal conditions, generally liquid header and liquid distribution trough are used simultaneously, form liquid collection and apparatus for redistributing.The effect of liquid header is by the liquid collection under the filler stream of upper strata, then delivers to liquid distribution trough and carries out liquid and distribute.Liquid header commonly used is the ramp type liquid header.
As previously mentioned, trough-tray liquid distributor has the function of liquid collecting and separatory concurrently, therefore trough-tray liquid distributor is good liquid collection and apparatus for redistributing.
As one of the utility model embodiment, described liquid distribution trough is straight pipe with holes formula spray thrower.
Gaseous mixture advanced distribution device in gas-fluid after entering at normal temperatures and pressures at the bottom of absorption tower, and the absorbent counter current contacting by the pump lifting with tower top gets off, absorb ammonia.Go out the purified gas reclaiming clean utilization of tower, the absorption liquid that has absorbed ammonia is promoted and is entered desorber by pump, after the superheated steam counter current contacting, separates the ammonia desorbed and recycles, and the liquid that tower bottom flow goes out enters absorption tower and recycles.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
