Abstract
The utility model discloses a high-temperature quenching and harm-removing three-in-one graphite falling film absorber which comprises a multitubular or cylindrical block graphite falling film absorbing section, a material charging section disposed at the upper end of the graphite falling film absorbing section; a tower type tail gas absorbing and separating section disposed at the lower end of the graphite falling film absorbing section. The utility model has a reasonable structure; a tower structure is combined with the falling film absorber, and the two structures have complementary advantages; tower structures such as a spraying type, a grid plate type, a bubble cap type, a floating valve type, or an overflow pipe type are combined with the upper part of an original falling film absorber, which can rapidly reduce the temperature of intake gas. A gas-liquid separator at the bottom of the original falling film absorber is modified, and combined with a spraying structure, a material filling structure, a sieve plate, a bubble cap or a floating valve structure, and secondary absorption is performed by clean liquid so as to reduce the content of the absorbed gas in discharged tail gas; and a low-concentration solution formed by absorbing the low-concentration gas by the clean liquid can be used as an absorption liquid in the process flow for recycle.
Description
Technical field
The utility model relates to a kind of graphite falling film absorber.
Background technology
, emit under the situation of a large amount of dissolvings (absorption) heat during at gas, adopt the falling-film absorber of dividing wall type cooling to have clear superiority than tower absorption by liquid-absorbent.Shell and tube (or graphite block heat exchanger) graphite falling film absorber for example; Can be passed to cooling fluid (for example water) by partition (tube wall or piece hole partition) material very soon because of the heat of solution in its absorption process reduces absorption gas, liquid temp; Thereby raising absorption efficiency; Thereby HCl (or HF or other) gas and need absorb into higher concentration solution (example hydrochloric acid, hydrofluoric acid, phosphoric acid, sulfuric acid etc.) time; Generally adopt graphite falling film absorber (shell and tube or graphite block heat exchanger), but the design temperature of standard type graphite falling film absorber is 170 ℃.
But, under certain conditions, often be forced in the system design and need add corollary equipment before or after the above-mentioned falling-film absorber owing to following reason:
When intake air temperature is higher (for example>180 ℃), is forced in and increases cooler between the graphite falling film absorber because of surpassing the current device standard-required, and thereby increase supporting pipeline, pipe fitting.
Owing to there is the gas that is absorbed on the solution interface after absorbing in the gas corresponding to solution concentration; And increase an absorption tower (normally packed tower) after being forced in falling-film absorber; To the absorption of removing the evil of above-mentioned tail gas, be absorbed gas to guarantee that discharging tail gas reaches environmental requirement and reclaims.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of the utility model is to provide, and allows the intake air temperature height, has the high temperature chilling of the performance of removing the evil and the three-in-one graphite falling film absorber of removing the evil.
Technical solution of the present invention is:
A kind of high temperature chilling and the three-in-one graphite falling film absorber of removing the evil; Comprise shell and tube or graphite block heat exchanger graphite falling film absorption section; It is characterized in that: graphite falling film absorption section upper end is provided with tower charging quench zone, and graphite falling film absorption section lower end is provided with tower tail gas absorption and separation section.
The absorption portion of said tower tail gas absorption and separation section is material filling type, sieve-board type, bubble-cap formula, float-valve type or overflow tubular type version.
Said tower charging quench zone is fountain, screen formula, bubble-cap formula, float-valve type or overflow tubular type version.Periphery at tower charging quench zone is provided with cooling water jecket.
The present invention is rational in infrastructure, and tower structure is combined in the falling-film absorber, with two kinds of structural advantage complementations, promptly is combined into tower structures such as fountain, screen formula, bubble-cap formula, float-valve type or overflow tubular type on former falling-film absorber top, can reduce intake air temperature rapidly.Former falling-film absorber bottom gas-liquid separator is revised; And be combined into spray structure, filling-material structure, sieve plate, bubble-cap or float valve structure; And carry out secondary with clean liquid (for example water) and absorb; Be absorbed gas content to reduce in the discharging tail gas, and the low concentration solution that forms behind the light concentration gas of clean liquid absorption here can be used as absorption liquid reuse in the flow process.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2, Fig. 3 are respectively the structural representation of standard type graphite block heat exchanger graphite falling film absorber and tube-type graphite falling-film absorber in the prior art.

The specific embodiment
A kind of high temperature chilling and the three-in-one graphite falling film absorber of removing the evil comprise shell and tube or graphite block heat exchanger graphite falling film absorption section 2, and graphite falling film absorption section upper end is provided with feed zone 1, and graphite falling film absorption section lower end is provided with tower tail gas absorption and separation section 3.
The absorption portion of said tower tail gas absorption and separation section is material filling type, sieve-board type, bubble-cap formula, float-valve type or overflow tubular type version.
Said tower charging quench zone is fountain, screen formula, bubble-cap formula, float-valve type or overflow tubular type version.
During work, carry out spray liquid with absorption liquid and carry out the fountain chilling, it is lowered the temperature in order to the falling film absorption of hypomere rapidly.The feed liquor place can adopt on the sieve plate aperture and retaining weir spray, can adopt also that the brill aperture sprays feed tube, tube on, and inlet can be in the side position, also can be at the top; The sieve plate form can adopt circle to lack the shape sieve plate by v-notch combined spray on aperture and the retaining weir; Also can adopt equilateral triangle or the downcomer type of arranging such as square distribution grid or grizzly bar shape, grill-shaped distribution grid more again; Perhaps with they Combination application; When intake air temperature is higher, then increase the sieve plate number to improve cooling effect.
Tower charging quench zone can also be screen formula, bubble-cap formula, float-valve type or overflow tubular type version.
Said tower tail gas absorption and separation section can be discharged the product liquid (C manages discharge) after the separation, gas (tail gas) is carried downwards in order to tail gas absorbed; Will make the liquid (for example water) of the cleaning of increase advanced can spray equably behind the equipment by the feed tube (G pipe) that increases simultaneously flows down; And in tail gas and clean liquid flow downward process, set up tower structure and make it increase contact area and stirring; Absorb in order to secondary, the secondary tail gas of being exported by bottom D pipe at last contains the unstrpped gas composition greatly to be reduced; Make absorption liquid and can reclaim into the B pipe by the circulation fluid (or cleaning solution) that bottom H pipe is discharged, but or qualified discharge; G pipe place adopts bubble-cap-sieve-board type structure, also can adopt and bore the structure of a large amount of aperture cloth liquid on simple feed tube, the tube or increase conventional liquid distributing plate structure more separately.
The absorption portion of said tower tail gas absorption and separation section can also be sieve-board type, bubble-cap formula, float-valve type or overflow tubular type tower structure form.
