Description
Technical field
The utility model relates to mass transfer in Chemical Engineering, heat-transfer equipment field, specifically a kind of stereoscopic film spray percolation tower tray.
Background technology
Chinese utility model patent ZL01221920.7 discloses a kind of Guide spray tower, has installed Guide spray separating plate to reduce mixture foam entrainment above jet cover, improves plate efficiency.Chinese utility model patent ZL01224885.1 discloses a kind of nozzle baffle type tower tray, installs two pieces of separating plates to reduce thing foam entrainment in the below of air rising hole.Chinese utility model patent ZL99200122.6 discloses a kind of radial side guiding jet column tray, the surrounding and fluid-tight cover of jet cover has been installed guide plate to prevent the back-mixing of liquid, reduces column plate resistance.Although above method serves the effect improving mass-transfer efficiency to a certain extent, but the stereo-spray tower tray that liquid mode falls in current traditional downspout still also exists, and liquid flow-disturbing on tower tray is serious, ejection efficiency is by problems such as liquid layer hydraulic gradient restrictions on tower tray, and these problems are along with the transformation of job platform type, the development trend maximized as offshore operations platform or tower can be more serious.Therefore develop a kind of mass-transfer efficiency high, the Novel tower meaning more adapting to following various working operation is very great.In Conventional plate-type tower distillation technology, upper strata feed liquid arrives lower floor by downspout, and liquid leans on gravitional force in the flowing of tower tray.When tower diameter is comparatively large or tower tray installation level is inadequate or when causing tower body to rock because of extraneous factor, liquid flow-disturbing mixed flow is serious, affects mass-transfer efficiency.
Utility model content
Problem to be solved in the utility model is: overcome the deficiencies in the prior art, provides one to solve tower, and especially on large-scale tower tower tray, liquid flow-disturbing mixed flow is serious, improves mass-transfer efficiency, reduces the stereoscopic film spray percolation tower tray of thing foam entrainment.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: providing a kind of stereoscopic film to spray percolation tower tray, is that one utilizes overflow cloth film, gas-liquid injection strengthening mass transfer, the high-efficient tower plate of percolation flowing,
Comprise tower body and the column plate being arranged on tower body inside, and be arranged on the jet cover on column plate; Described column plate is provided with several fixing holes, a guide shell is all fixed with in each fixing hole, described guide shell sidewall outer ring is provided with liquid seal trough, air rising hole is had bottom described liquid seal trough, described air rising hole is concentric with fixing hole, described guide shell sidewall inner ring is provided with jet cover, jet cover side wall lower ends face and liquid seal trough bottom welding; The sidewall of jet cover has some spray-holes, and top is provided with top cover, and upper end is provided with submerged soil; Described guide shell sidewall is coaxially connected with jet cover outer wall and liquid seal trough sidewall, all leaves gap, leave gap between described top cover and jet cover between guide shell sidewall and jet cover outer wall and liquid seal trough sidewall.
During distillation operation, liquid, from the liquid seal trough overflow of upper level column plate, flows under the influence of gravity into submerged soil, along the gap of jet cover and top cover, adherent of film forming and under, with jet cover enclose the gas phase moved upward in cavity and carry out counter current contacting.When liquid stream is through spray-hole, first partially liq is broken into drop by with certain gas speed rising steam flow, is sprayed by spray-hole; Remaining liq then continues to decline, near air rising hole, again broken by rising steam flow, carries out abundant mass-and heat-transfer, and under the drive of gas phase, sprays from spray-hole.The vehicle repair major of ejection realizes being separated under gravity.
Further, described column plate is provided with liquid separatnig plate, tray surfaces is divided into several mutually isolated regions.Preferably, this mutually isolated region is groined type or regular hexagon
The liquid phase of such ejection falls the mutually isolated region be divided into by liquid separatnig plate to column plate after rise, then along the gap between guide shell and jet cover sidewall, enters liquid seal trough, and enters descending trays from the gap overflow of guide shell and liquid seal trough sidewall.Vapour phase is then walked around submerged soil and is risen, and enters upper jet cover, realize heat and mass again from upper strata jet cover air rising hole.
Preferably, the big up and small down type of described submerged soil.
Further, described jet cover is that longitudinal projection's profile is similar to air rising hole, and can be circle, rectangle or other polygons, diameter slightly larger than air rising hole, and keeps concentric with air rising hole.
Preferably, described spray-hole is circle, bar shaped or polygon.The arrangement of described spray-hole is in staggered, parallel or arranged side by side mode.
The advantage that the utility model has and good effect are: (1) is by setting up submerged soil in jet cover upper end, mass transfer area is made to change solid space into by plate face liquid layer, increase the flowing time of liquid in jet cover, increase column plate space availability ratio, thus mass-and heat-transfer efficiency is improve 10% ~ 30%, simultaneously leak of liquid amount comparatively conventional stereo jet tray decrease 50% ~ 90%; (2) downspout of Conventional plate-type tower is eliminated, by setting up liquid separatnig plate, guide shell and liquid seal trough, achieve the percolation effect of liquid, solve the problem that on large-scale tower tower tray, liquid flow-disturbing mixed flow is serious, be particularly useful for the situation (such as ocean platform) that rectifying platform has or rocks; (3) in the utility model because liquid seal trough is positioned at below tray level, and by the stop of submerged soil, make rising steam flow successively through the stop of submerged soil and liquid seal trough, produce twice flow-disturbing, well reduce thing foam to carry secretly, thing foam is carried secretly and decreases 20% ~ 50%.
