Abstract

The utility model discloses a bubble column converter used at a process for the production of acetic acid by a liquid phase of methanol oxo synthesis under a lower pressure. The utility model mainly consists of a column body and a gas distributor located at the lower section of the column body with a diameter height rate of 5 to 6. The gas distributor is a dual-ring porous gas distributor with a rate of the mean diameter of an external annular pipe to the column diameter at a level from one half to one third. About 80 to 90 per cent holes spray upwards with two neighboring holes forming an included angle from 45 degrees to 60 degrees but a range from 45 degrees to 50 degrees preferred; the rest 20 to 10 per cent holes spray vertically downwards. The utility model is characterized by a well effect of mass transfer, a small outline of reactor and high conversion efficiency.

Description

The acetic acid synthesized technology of low-pressure methanol liquid phase carbonyl bubble tower convertor
The utility model belongs to chemical industry equipment, makes the field in particular for the conversion unit of acetic acid synthesis process by low-pressure methanol carbonylation.
Chinese invention patent (ZL92108244.4) provides a kind of low-pressure methanol liquid phase carbonyl acetic acid synthesized method, and being characterized in increases a convertor after the reactor in conventional process flow.After reaction solution enters convertor, proceed carbonylation reaction, the methyl alcohol degree of depth is transformed with the carbon monoxide that adds.But the convertor equipment that does not have at present the use that processing condition with it match.
The purpose of this utility model is, designs the special-purpose bubble tower convertor that a kind of and above technology matches and uses, and makes it to have higher transformation efficiency and good mass transfer effect.
The purpose of this utility model is to realize by following means.
The acetic acid synthesized technology of low-pressure methanol liquid phase carbonyl bubble tower convertor mainly by tower body with place the gas distributor etc. of tower body bottom to form, is characterized in that the blade diameter length ratio of bubble tower convertor is 5~6; The gas distributor of bubble tower convertor is a dicyclic porous gas sparger, and the footpath is 1/2~1/3 with the ratio of tower diameter in its outer endless tube; 80%~90% aperture upwards sprays, and adjacent two holes are at 45 mutually~60 ° of angles, be preferably 45 °~50 ° angles, 20%~10% aperture sprays downward vertically; Aperture is uniform distribution on two rings.
After adopting design as above, effectively mass transfer area improves, and can satisfy the requirement that the degree of depth transforms in the carbonyl synthesis acetic acid technology.
Description of drawings is as follows:
Fig. 1 is the longitudinal sectional view of the utility model embodiment.
Fig. 2 is the part figure of dicyclic porous gas sparger.
Fig. 3 is a dicyclic porous gas sparger position of opening graph of a relation.
Fig. 4 is the longitudinal sectional view of the utility model band self-absorbing type stirrer embodiment.
Below in conjunction with accompanying drawing structure of the present utility model is described in further detail.
Can see in conjunction with Fig. 1, Fig. 2 and Fig. 3, form tower body by inlet pipe 1, escape pipe 2, liquid-blocking device 3, overflow weir 4, drain pipe 5, liquid-leaking nozzle 6, tower tube 7, liquid-inlet pipe 8 etc.The blade diameter length ratio of bubble tower convertor is 5.5; The gas distributor 9 of bubble tower convertor is a dicyclic porous gas sparger, and the footpath is 0.4 (1/2~1/3) with the ratio of tower diameter in its outer endless tube; 90% aperture upwards sprays, and the angle of cut α of the axial connecting line in adjacent two holes is 45 °~60 ° angles, is preferably 45 °~50 ° angles, and 10% aperture sprays downward vertically; Aperture is uniform distribution on two rings.The aperture total sectional area be tower section long-pending 0.35%~0.38%.
Convertor of the present utility model can adopt two kinds of structures: a kind of is the structure of above embodiment, constitutes the full back-mixing in bottom, the streamlined bubble tower in middle and upper part, is applicable to the situation that carbon monoxide pressure of tension is higher; When carbon monoxide pressure of tension in the reactor tail gas is low, adopt the structure of Fig. 4 embodiment, constitute the bubble tower of the full back-mixing in bottom, middle part laminar flow, the self-priming stirring of top band, reaction end gas can be sucked in the liquid phase once again like this, to guarantee the transmission of convertor top carbon monoxide.In Fig. 4, in the structure of a last embodiment, set up a self-absorbing type stirrer 10, mixing device paddle diameter is 1/3~1/2 of tower diameter.
