Abstract
The utility model discloses a compounded methanol rectification tower consisting of a tower body and the tower inner device which forms the stripping section and the rectification section; the utility model is characterized in that the upper part of the tower inner device is the feeding tower part and the lower part is the board-style tower part, the methanol liquid input device is arranged at the middle of the tower body. The utility model relating to new compounded methanol rectification tower integrates the advantages of board-style tower and the high efficient feeding tower, overcomes the defects of the mentioned two tower, which is a perfect methanol rectification tower that is able to improve the rectification efficiency and satisfy the stable operating in long period.
Description
The utility model belongs to chemical industry equipment and makes the field.
In the existing methanol device, rectifying column generally adopts plate column or high-efficiency packing tower.Board-like methanol rectifying tower advantage: smooth operation, stifled tower, operating flexibility is big, and the adaptability of thick methyl alcohol than broad, has been accumulated the experience of abundant long-term operation.Shortcoming: under identical scale condition, to compare tower diameter bigger with high efficiency packing, and the number of plates is more, and the tower total height is higher, and the energy consumption of unit product is higher.High efficiency packing methanol rectifying tower advantage: compare with plate column, filler efficient is higher, and reflux ratio is also lower, so under identical scale condition, tower diameter is less, the height of tower is lower, and the energy consumption of unit product is also lower.Shortcoming: the structured packing of stopping up stripping section (hypomere of tower) easily when fusel in the thick methyl alcohol or when having wax to generate, harsher to the requirement of distributor when the composition of thick methyl alcohol changes, amplifying efficient should be poor.
The purpose of this utility model is the methanol rectifying tower of a kind of novel suitable methyl alcohol reparation technology of design, makes it the advantage of compatible packed tower and plate column, its shortcoming of sublating, and reach simple in structure, easy to operate effect.
The purpose of this utility model is to realize by following means.
By tower body with constitute the combined type methanol rectifying tower that device constitutes in the tower of stripping section and rectifying section, installing top in the tower is packing tower section, and the bottom is the plate column section; The methanol solution import is arranged on the tower body middle part.At this, the tower body middle part comprises tower body stage casing and middle hypomere position.
Adopt structure as above, the combined type methanol rectifying tower combines the advantage of plate column and high-efficiency packing tower, has overcome two kinds of towers shortcoming separately, is to improve rectification efficiency, can satisfy a kind of comparatively desirable methanol rectifying tower of long-period stable operation again.Its characteristics are as follows:
Rectifying section (being epimere) mainly adopts high efficiency packing (also the part tower tray may be set), and handled material is the methanol aqueous solution and the methanol steam of cleaning, can not stifled tower.Therefore, guaranteeing under the prerequisite that liquid phase is evenly distributed, just can give full play to the advantage function of high efficiency packing.
Stripping section (being hypomere) mainly adopts plate column (also the part high efficiency packing may be set), flow channel for liquids is bigger, even at the driving initial stage, catalyst powder and other impurity content of thick methyl alcohol are more, perhaps also be mingled with a small amount of paraffin, also can not stop up tower tray in normal operation or after stopping, this point is confirmed in operating experience for many years.
In addition, do not establish the extraction mouth at rectifying section, stripping section is provided with side line extraction mouth, owing to adopt the tower tray internals, so the extraction mouth structure is simple, operating maintenance is convenient.
Description of drawings is as follows:
Fig. 1 is for adopting methanol rectification cell process route map of the present utility model
Fig. 2 is the cutaway view of the utility model combined type methanol rectification.
Below in conjunction with structure of the present utility model is described in further detail.
In Fig. 1 and Fig. 2,1 is the utility model tower body, and device top is packing tower section in the tower, and the bottom is the plate column section; 2 is the methanol solution import, is arranged between packing tower section and the plate column section; 3 are the phegma inlet, and 4 are the overhead vapours outlet, and 5 and 8 is liquid distribution trough, and 6 is the high efficiency packing layer, and 7 is the filler gripper shoe; 9 is downspout, and 10 is tower tray, and 11 is liquid outlet at the bottom of the tower, and 12 is the circulation fluid outlet, and 13 is the liquid-vapor mixture import; 14 is tower bottom reboiler, and 15 is condenser.By seeing among the figure, remove light component prognosis methyl alcohol through being pumped to the middle and lower part of rectifying column, methanol steam and a spot of liter waterborne enter into the high efficiency packing layer in the tower, carry out mass-and heat-transfer with reverse contact of the phegma of cat head, and will flow downward after the heavy ends condensation, last pure methyl alcohol leaves cat head, is condensed into liquid methanol in overhead condenser, most of methyl alcohol is got back to cat head as phegma, extracts a part out as methanol product.Part methyl alcohol in the prognosis methyl alcohol, water, high-boiling components, other impurity and a little paraffin enter the tower still after each layer of hypomere tower tray isolated most of methyl alcohol, by getting rid of at the bottom of the tower and delivering to next process.Main distillation column institute calorific requirement is provided by tower bottom reboiler.
The utility model combined type methanol rectifying tower has been contained pre-distillation column in the two tower methanol rectification technologies and pre-distillation column, compression rectification tower and the atmospheric distillation tower in main distillation column and the three tower methanol rectification technologies.Make process equipment and flow process also compact more.
Certain methyl alcohol compression rectification tower:
Rectifying section dress high efficiency packing, packed height is: 20 meters, establish four sections fillers altogether, every section height is: 5 meters, the filler gripper shoe is established in every section filler bottom, and epimere is provided with liquid distribution trough.Stripping section is provided with 8 blocks of column plates, and every block of column plate is made up of tower tray, downflow weir, downspout etc.
It is pointed out that generally speaking the methanol solution import is arranged between packing tower section and the plate column section.Like this, packing tower section of the present utility model is finished the work of rectifying section, and its plate column section is finished the work of stripping section; But do not get rid of the way that the methanol solution import is arranged on other adjacent position, tower body middle part yet.Such as, the methanol solution import is arranged on the hypomere of packing tower section or is arranged on the epimere of plate column section.
