Abstract
The utility model discloses a falling film absorption column which comprises a casing (1), an upper fixed tube sheet (2), an absorber head (3) equipped with a distribution unit (5), a cooling absorption section (4) and an gas-liquid separation section (6) and is characterized in that the cooling absorption section (4) is made of a graphite modified polypropylene material; and the casing (1), the upper fixed tube sheet (2), the absorber head (3) and the gas-liquid separation section (6) are all made of a polypropylene material. The falling film absorption column disclosed by the utility model has high absorption efficiency, good corrosion-resistant performance, light weight, high temperature resistance, low probability of deposit, long service life and convenience in maintenance, and is applicable to the absorption of exothermic chlorine hydride or sulfur dioxide and other eutectic corrosive gases.
Description
Technical field
The utility model relates to a kind of absorption tower, is specifically related to a kind of graphite modified polypropylene film-falling absorption tower.
Background technology
Not enough below traditional graphite membrane absorber exists: one, decay resistance is relatively poor, and shell and securing member all are iron, in the environment of corrosive gas, is corroded very soon and scraps; Two, proportion is bigger, and bad mechanical strength is unfavorable to transportation, installation, use, the maintenance of equipment; Three, non-refractory is prone to fouling, has reduced heat transfer coefficient; Four, narrow application range, efficient is lower.
The utility model content
The purpose of the utility model is to deficiency of the prior art; A kind of membrane absorber of graphite modified polypropylene material is provided; It had both had the high advantage of membrane absorber absorption efficiency of graphite material, can overcome many deficiencies of the membrane absorber of graphite material again.
For accomplishing above-mentioned purpose; The technical scheme that the utility model adopts is: a kind of film-falling absorption tower; Comprise housing, top fixed tube sheet, absorber head, cooling down absorption segment and gas-liquid segregation section; Said absorber head is provided with distribution apparatus, it is characterized in that: said cooling down absorption segment is processed by graphite modified polypropylene material, and said housing, top fixed tube sheet, absorber head and gas-liquid segregation section are processed by polypropylene material.
Compare with existing graphite membrane absorber, the beneficial effect of the utility model is:
1, high, the corrosion resistance and good of absorption efficiency: shell is the polypropylene material, in the environment of corrosive gas, is difficult for being corroded.2, proportion is little, and is in light weight, and mechanical strength is big, make things convenient for equipment transportation, install, use and keep in repair.3, heatproof is higher: serviceability temperature can reach 110-120 ℃.4, less scaling, improved heat transfer coefficient.5, be prone to dissolve the absorption of corrosive gas applicable to the hydrogen chloride of following heat release or sulfur dioxide etc.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the cross-sectional view of the utility model;
Among the figure: 1, housing, 2, the top fixed tube sheet, 3, the absorber head, 4, cooling down absorption segment, 5, distribution apparatus, 6, the gas-liquid separation section, 7, tubulation; The A liquid outlet, B cooling water inlet, C coolant outlet, D gas feed, E liquid-inlet, F gas vent.
The specific embodiment
As shown in Figure 1, a kind of film-falling absorption tower comprises housing 1, top fixed tube sheet 2, absorber head 3, cooling down absorption segment 4 and gas-liquid segregation section 6.Housing 1 bottom is provided with liquid outlet A; The sidewall of gas-liquid separation section 6 is provided with gas vent F; Cooling down absorption segment 4 top sidewalls are provided with coolant outlet C, and lower sidewalls is provided with cooling water inlet B; The sidewall of absorber head 3 is provided with gas feed D and liquid-inlet E.The top fixed tube sheet is the cooling down absorption segment 4 for being processed by graphite modified polypropylene material below 2; Its structure is basic identical with general fixed tube-sheet exchanger; Said cooling down absorption segment 4 is the tubulation 7 of graphite modified polypropylene material, in walk absorbent and absorb gas, walk cooling agent between pipe.The top fixed tube sheet is called absorber head 3 more than 2, in distribution apparatus 5 is arranged, guarantee that absorbent is distributed in every root absorption pipe equably, and form film toward dirty at inside pipe wall.Said housing 1, top fixed tube sheet 2, absorber head 3 and gas-liquid segregation section 6 are processed by polypropylene material.Absorbent descends with film like along vertical tube 7 inwalls through distribution apparatus 5 during operation, gas from top to bottom, gas-liquid two-phase carries out mass transfer on the liquid film that flows.Tubulation 7 outer coolants are to remove liberated heat in the absorption process.
The foregoing description is as to the qualification of the utility model, all any modifications of in the scope of the utility model, being done, is equal to replacement, improvement etc., all belongs to the protection domain of the utility model.
Claims (2)
1. film-falling absorption tower; Comprise housing (1), top fixed tube sheet (2), absorber head (3), cooling down absorption segment (4) and gas-liquid segregation section (6); Said absorber head (3) is provided with distribution apparatus (5); It is characterized in that: said cooling down absorption segment (4) is processed by graphite modified polypropylene material, and said housing (1), top fixed tube sheet (2), absorber head (3) and gas-liquid segregation section (6) are processed by polypropylene material.
2. film-falling absorption tower according to claim 1 is characterized in that, said cooling down absorption segment (4) is the tubulation (7) of graphite modified polypropylene material.
