The specific embodiment:
In order to make creation characteristic of the present invention, technological means and to reach object, be easy to understand understanding, below in conjunction with accompanying drawing, further set forth the present invention.
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 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, also can be 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 being 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, hold down gag is installed in spraying rack top can prevent that 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 is freely positioned over 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 bed confinement plate is made for metal, plastics etc.Bed confinement plate will be fixed on Ta Bishang, for not affecting installation and the use of liquid distribution trough, can not adopt continuous tower circle to fix, and for trourelle, can be fixed on Ta Bi with screw, and large tower is fixed with journal stirrup.
Disc type distributor has the forms such as disc grizzly pass distributor, disc type overflow pipe distributor.Liquid adds on distributing disc, through sieve aperture or overflow pipe, flows down.Distributing disc diameter is 0.6～0.8 times of tower diameter, and this kind of distributor is used for the tower of D < 800mm.
Pipe distributor is made by the tube having holes of different structure form.Its outstanding feature is 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.Tubular liquid distributor uses very extensive, is used in the packed tower of low middling liquid load.In rectification under vacuum and screen waviness packings tower, thus due to liquid load less conventional it.Pipe distributor has the difformities such as calandria, annular tube type.According to 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).One-level groove is just divided into some stream strand by 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, the separated occasion that is particularly suitable for large gas-liquid load and contains 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.
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.
Liquid collection and apparatus for redistributing, when liquid flows downward along packing layer, have the mobile phenomenon of deflection tower wall, and this phenomenon is called wall stream.Wall stream will cause gas-liquid skewness in packing layer, and mass-transfer efficiency is declined.For reducing wall flow phenomenon, can liquid redistribution device be set interval certain altitude 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.Conventional liquid header is 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 embodiment of the present invention, described liquid distribution trough is straight pipe with holes formula spray thrower.
Gaseous mixture entered distribution device in gas-fluid after entering at normal temperatures and pressures at the bottom of absorption tower, and the absorbent counter current contacting being promoted by pump with tower top gets off, absorbs 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, and after superheated steam counter current contacting, the ammonia that separation desorbs is also recycled, and the liquid that tower bottom flow goes out enters absorption tower and recycles.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
