Abstract
The utility model discloses a two-in-one graphite falling film absorber with a harm-removal tower, which comprises a feeding section, a tube type or round block type graphite falling film adsorbing section is arranged below the feeding section; and the lower end of the graphite falling film adsorbing section is provided with a tower-type tail gas adsorption and separation section. The two-in-one graphite falling film absorber has a novel structure, a gas-liquid separator on the bottom of the original falling film absorber is revised and is combined with a spraying structure, a filler structure, a sieve plate, a bubble cap or a floating valve structure, clean liquid is used for secondary adsorption to lower the content of adsorbed gas in the discharged tail gas, and low-concentration solution formed after the clean gas adsorbs the low-concentration gas can be reused as the adsorption liquid in a flow.
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 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, this has just increased equipment and pipeline.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of the utility model is to provide, and has the two-in-one graphite falling film absorber of tower of removing the evil joining of the performance of removing the evil.
Technical solution of the present invention is:
A kind of two-in-one graphite falling film absorber of the tower of removing the evil of joining comprises feed zone, and shell and tube or graphite block heat exchanger graphite falling film absorption section are set under the feed zone, and it is characterized in that: 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 tower structure form.
The present invention is rational in infrastructure; 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 clean liquid absorbs the low concentration solution that forms behind the light concentration gas and can be used as absorption liquid reuse in the flow process here.
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 two-in-one graphite falling film absorber of the tower of removing the evil of joining comprises feed zone 1, and shell and tube or graphite block heat exchanger graphite falling film absorption section 2 are set under the feed zone, and graphite falling film absorption section lower end is provided with tower tail gas absorption and separation section 3.
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.
Claims (2)
1. join the two-in-one graphite falling film absorber of the tower of removing the evil for one kind, comprise feed zone, shell and tube or graphite block heat exchanger graphite falling film absorption section are set under the feed zone, it is characterized in that: graphite falling film absorption section lower end is provided with tower tail gas absorption and separation section.
2. the two-in-one graphite falling film absorber of the tower of removing the evil of joining according to claim 1 is characterized in that: 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 tower structure form.
