Abstract
The utility model discloses a falling film absorption tower used for recovering sucralose waste gas. The falling film absorption tower comprises an absorption tower body, wherein the absorption tower body is sequentially divided into a liquid film distribution section, a recovery cooling section and a gas separation section from top to bottom, wherein a plurality of falling film pipelines are vertically arranged in the recovery cooling section, the upper ends of the falling film pipelines extend into the liquid film distribution section, a cooling water inlet and a cooling water outlet are formed in a shell of the recovery cooling section, the recovery cooling section is isolated from the liquid film distribution section by the bottom of the liquid film distribution section, an absorption liquid inlet is also formed in the liquid film distribution section and connected with a pipeline, the open end of the pipeline is close to the bottom of the liquid film distribution section, the edges of the upper ends of the falling film pipelines are in the shape of sawtooth waves, and a gas outlet is formed in the gas separation section. The falling film absorption tower disclosed by the utility model is simple in structure, and avoids unevenness of liquid films by increasing the roughness of the inner walls of the falling film pipelines.
Description
Technical field
The utility model relates generally to the film-falling absorption tower of the recovery of the acid waste gas producing in sucrose trichloride production process.
Background technology
Sucralose meeting in process of production at present produces acid waste gas, if the very big contaminated environment of the direct emptying meeting of this waste gas adopts waste gas recovery tower to absorb conventionally, easily causes the remaining product waste of part in waste gas.And film-falling absorption tower has heat exchange good absorbing effect, and can reclaim the function of waste gas, but in common film-falling absorption tower, absorption liquid is difficult in falling liquid film pipeline sprawl completely carry out heat exchange absorption, causes absorption efficiency lower.
Summary of the invention
Goal of the invention: for problem and the defect of above-mentioned existence, the utility model provides a kind of film-falling absorption tower reclaiming for Sucralose waste gas, and absorption efficiency is higher.
Technical scheme: to achieve the above object of the invention, the utility model is by the following technical solutions: a kind of film-falling absorption tower reclaiming for Sucralose waste gas, comprise absorption tower body, this absorption tower body is divided into successively from top to bottom liquid cloth film section, reclaims cooling section and gas fallaway section, wherein reclaim cooling section and vertically arrange many falling liquid film pipelines, liquid cloth film section is stretched in falling liquid film pipeline upper end, and the housing of described recovery cooling section is provided with cooling water inlet and coolant outlet; Described liquid cloth film section bottom will reclaim cooling section and liquid cloth film section is isolated, described liquid cloth film section is also provided with absorption liquid import, this absorption liquid import is connected with pipeline, and the openend of this pipeline is near liquid cloth film section bottom, and the upper ora terminalis of described falling liquid film pipeline is sawtooth waveforms shape wave; Described gas fallaway section is provided with gas vent.
As preferably, the bottom of described recovery cooling section is provided with cleaning sewage draining exit.
As preferably, described falling liquid film pipeline is made up of stainless steel, and the roughness of inwall is 15～30Ra.
As preferably, it is 5～12cm that described falling liquid film pipeline exceeds the height that reclaims cooling section.
Beneficial effect: compared with prior art, the utlity model has following advantage: simple in structure, thus and avoid the inhomogeneous of liquid film by the roughness that improves falling liquid film inner-walls of duct.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, liquid cloth film section 1, recovery cooling section 2, gas fallaway section 3, falling liquid film pipeline 4, cooling water inlet 5, coolant outlet 6, absorption liquid import 7, cleaning sewage draining exit 8.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment and only be not used in restriction scope of the present utility model for the utility model is described, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
As shown in Figure 1, a kind of film-falling absorption tower reclaiming for Sucralose waste gas, comprise absorption tower body, this absorption tower body is divided into successively from top to bottom liquid cloth film section, reclaims cooling section and gas fallaway section, wherein reclaim cooling section and vertically arrange many falling liquid film pipelines, this falling liquid film pipeline adopts stainless steel to make, and the roughness of inwall is controlled at 25Ra left and right, liquid cloth film section is stretched in falling liquid film pipeline upper end, and exceeding the height that reclaims cooling section is 10cm, the housing of described recovery cooling section is provided with cooling water inlet and coolant outlet, and bottom is provided with cleaning sewage draining exit; Described liquid cloth film section bottom will reclaim cooling section and liquid cloth film section is isolated, described liquid cloth film section is also provided with absorption liquid import, this absorption liquid import is connected with pipeline, and the openend of this pipeline is near liquid cloth film section bottom, and the upper ora terminalis of described falling liquid film pipeline is sawtooth waveforms shape wave; Described gas fallaway section is provided with gas vent.
