Abstract
The present invention relates to a kind of Wavelike plate distillation tower, belong to the chemical industry gas-liquid mass transfer (contact) equipment.This tower adopts rectangle tower body, and column plate is formed by the mutual crosslinked overlap joint of several waveform elements, forms the slick and sly gas passage that rises between the adjacent elements.This tower structure is simple, good separating effect, column plate and rise all smooth Wugou of gas passage, thorn, be difficult for hook fiber class foreign material, material is subjected to the uprising gas driving to be one-way flow on the plate, and the holdup time is short, and silt, foreign material are difficult for deposition, be particularly suitable for containing the distillation of the material of more solid suspension, equally also can be used for the rectifying of ordinary material.
Description
The present invention relates to a kind of board-like steaming
Tower belongs to the chemical industry gas-liquid mass transfer (contact) equipment.
At present, be used for organic chemistry industrial treatment fermentation liquids such as alcohol, butanol acetone
Tower is continued to use common bubble column mostly.This pyramidal structure complexity is colluded the extension fiber sundries easily, so riser, bubble-cap slot and overflow pipe etc. very easily are blocked, and antifouling property is poor.Owing to generally all contain relatively large solid suspension in the above-mentioned zymotic fluid, so often in the production process stop production continually and draw tower, tear tower open because of blocking up tower, the eliminating dirt has a strong impact on production.Also because the interior uprising gas of bubble column is to spray to the four directions by slot, therefore air-teturning mixed phenomenon is serious onboard for material, holdup time is long, inferior separating effect, not only cause silt particle, foreign material deposition easily and stifled tower, and organic materials is subjected to the heating of long period onboard, is easy to generate new reaction, form new organic impurities, unfavorable to product quality.Also have and adopt the inclined hole plate column to handle this type of material, but it very easily colludes the extension fiber sundries, stifled tower phenomenon is serious, and to the load variations bad adaptability, operating flexibility is little, therefore seldom use.
The circular column plate of the many employings of above-mentioned plate column, tower body is cylindrical, and this column plate easily forms dead band or slow district in both sides, and in this zone, the gas-liquid loose contact influences separating effect, and foreign material deposit easily simultaneously, and then cause stifled tower.
These shortcomings in view of existence such as bubble column, inclined holes tower in the prior art, the objective of the invention is, provide a kind of simple in structure, good separating effect, be difficult for precipitated mud and sand, impurity, be difficult for colluding hang fiber sundries be suitable for handling the board-like steaming that contains the solid suspension material
Tower.
For achieving the above object, solution of the present invention is, adopts the rectangle tower body of four jiaos of band arcs, and column plate is formed by the mutual crosslinked overlap joint of several waveform elements, forms the slick and sly gas passage that rises between each adjacent elements.Respectively there is an end-plate that has several fumaroles at the two ends of column plate, and the two ends difference sealing-in of waveform element is on end-plate.This end-plate lower vertical is folded to rectangle inner wall of tower ， And and is fixed on the inner wall of tower by its two ends with column plate, thereby forms a narrow passage between end-plate and tower wall.Fumarole on the end-plate is venetian blind type, and the window leaf is opened to above-mentioned tower wall passage, and the eyelet in each hole and column plate horizontal plane are 30 ° of-60 ° of inclinations angle, and it is consistent that the expansion direction of angle and gas foam blow direction, promptly towards overflow pipe place direction.
The board-like steaming of waveform of the present invention
Tower, owing to adopt the waveform element, column plate and rise all smooth nothing of gas passage and collude, sting, material is difficult for being colluded extension, again since gas when rising the gas passage and enter column plate, form single way jet, be that everywhere bubble blows the direction unanimity on the tower, all towards the overflow pipe position, meanwhile, owing to adopt bigger superficial linear velocity in a column (1-1.5 meter per second) in this tower, stronger driving force is arranged, make material form one-way flow onboard, the material lagging time is short, improve the air-teturning mixed phenomenon of column plate greatly, improved separating effect.The advantage of bringing simultaneously is, because material is onboard constantly towards a direction operation, make its contained silt particle, impurity be difficult for deposition, careless, numb and so on fibrous matter is along with the unidirectional operation of material, be similar to the effect of " making a rope by twisting the strands together ", form " ropy " at last and easily at the bottom of tower, discharge.The present invention has been owing to adopted the rectangle column plate, and fluid is desirable " piston flow " state, several no dead angles, slow district and air-teturning mixed phenomenon during unidirectional operation on column plate.Passage that the present invention sets up at Ta Bichu and the fumarole on the end-plate, help eliminating the column plate dead angle, increase the gas-liquid contact-making surface, the material that promotes tower wall place moves to the overflow direction, avoid material to be detained and cause the impurity deposition, further improved the effective cross-section utilization rate of the stain resistance and the column plate of tower in this zone.
In sum, the board-like steaming of waveform
Tower has reached expected effect of the present invention, is particularly suitable for the wine with dregs tower of industry such as alcohol, butanol acetone as fermentation liquid, also can make thick (just) of general chemical industry simultaneously
Tower or essence
Tower uses.
Further specify embodiments of the invention below in conjunction with accompanying drawing:
Fig. 1 is the longitudinal profile schematic diagram of plate column of the present invention.
Fig. 2 is the cross sectional representation of Fig. 1 plate column.
Fig. 3 is the waveform element.
Fig. 4 is the end-plate structural representation.
Fig. 5 represents waveform column plate and the assembling schematic diagram on rectangle tower body one inwall thereof.
Number in the figure 1 is the waveform element, and 2 and 3 are respectively and rise the gas passage and bubble blows passage, and both are same passage in fact, the 4th, and overflow pipe, the 5th, tower body, the 6th, fumarole, the 7th, end-plate, the 8th, tower wall passage.
The upper limb of end-plate is in wave shape, during assembling, the crest and the end-plate crest of waveform element end are harmonious, the trough of element closes on the plate below the end-plate trough (as Fig. 4 dotted line position), subsequently along opening a fumarole corresponding to each crest on the welding of element end, the end-plate, eyelet and horizontal line are 45 ° of inclinations angle, add to adopt a punching press of mould man-hour, make the eyelet upper limb translate into the window leaf form outward.
