Abstract
The utility model provides a gas distributor of a reactor for low-pressure carbonyl synthesized acetate. The gas distributor comprises a porous ring-type pipe body with an air inlet, wherein the porous ring-type pipe body comprises an upper pipe body and a lower pipe body which are concentric, wherein the upper pipe body and the lower pipe body are communicated with each other through a connecting pipe, and the nominal diameter of the upper pipe body is larger than that of the lower pipe body. Therefore, an upper-and-lower layered structural style is formed, since the nominal diameter of the upper pipe body is different from that of the lower pipe body, air entering into the reactor is enabled to be more uniformly mixed with liquid, and the entire distributor has a simple and compact structure.
Description
Technical field
The utility model relates to technical field of chemical, and especially a kind of low pressure carbonyl synthesis acetic acid is with the gas distributor of reactor.
Background technology
The methanol carbonyl synthetic method is the industrial acetic acid production method of at present tool economy.Unstrpped gas gets into mixed solution and distributes behind the gas distributor bubbling; The size of bubble that unstrpped gas produces and distribution situation directly affect the conversion ratio of reaction rate and unstrpped gas; On 300,000 tons of annual outputs and above reaction unit, this there is higher requirement.At present, in the reaction unit that is adopted in the building-up process, gas distributor is an individual layer porous ring type body, because the restriction of pore angle makes the distribution of unstrpped gas can not reach uniform distribution, thereby influences prouctiveness.Existing in prior technology weak point that Here it is.
Summary of the invention
The technical problem that the utility model will solve is exactly not enough to existing in prior technology, and a kind of gas distributor that can make the equally distributed low pressure carbonyl synthesis acetic acid of unstrpped gas with reactor is provided.
This programme is realized through following technical measures: this low pressure carbonyl synthesis acetic acid comprises the porous ring type body that has air inlet with the gas distributor of reactor; Said porous ring type body comprises concentric upper tube body and lower tube body; Upper tube body and lower tube body are communicated with through tube connector, and the nominal diameter of upper tube body is greater than the nominal diameter of lower tube body.
After making unstrpped gas get into reactor, can distribute uniformly; The set-up mode of pore adopts following mode: several pores of different-diameter evenly are provided with along normal direction positive direction, normal direction ± 30 ° direction, normal direction ± 60 ° direction and the normal direction ± 90 ° direction of the first half of upper tube body and lower tube body, form seven circle spread patterns.
According to the different processes needs, the diameter of above-mentioned pore adopts 3～5mm, and the spacing between the adjacent pore is 3～5cm.
The arrangement mode of the pore of different-diameter on upper tube body and lower tube body can adopt following three kinds of forms: the formed circle of circle center line connecting of the pore that the pore that (1) every loop diameter is big and every loop diameter are little is concentric; (2) pore that diameter is big is serpentine at the corresponding circumferencial direction of upper tube body and lower tube body upper edge and arranges; (3) the formed circle of the circle center line connecting of every circle pore is concentric, and the big pore of diameter is " X " shape along the circumferencial direction of upper tube body and lower tube body and arranges.
This gas distributor is through the diameter of optimization pore and the arrangement mode of pore; Make unstrpped gas after the ejection of each pore place, can arrive the dissipation of breaking after the different distance according to predefined paths, under the situation that does not change current reactor and agitator thereof; Unstrpped gas has been realized distributing by different level; Under the condition that keeps tapping gas speed constant (perhaps smaller), the dynamic contact area between the gas-liquid is significantly increased, gas stirring action by agitator in the extremely short time is fully mixed with liquid; The distribution of gas effect is able to remarkable improvement, thereby promotes the efficient of gas-liquid phase reaction in the reactor.
The beneficial effect of this programme can be learnt according to the narration to such scheme; In the gas distributor of this low pressure carbonyl synthesis acetic acid with reactor; Described porous ring type body comprises concentric upper tube body and lower tube body; Upper tube body and lower tube body are communicated with through tube connector, and the nominal diameter of upper tube body is greater than the nominal diameter of lower tube body.So just formed bilevel version, again because upper tube body is different with the nominal diameter of lower tube body, institute so that get into the interior gas of reactor can more uniform and liquid mixing, and whole structure of distributor is simple, compact.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.

The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below through the specific embodiment, and combine its accompanying drawing, this programme is set forth.
A kind of low pressure carbonyl synthesis acetic acid is with the gas distributor of reactor; As depicted in figs. 1 and 2; It comprises the porous ring type body that has air inlet 5, and said porous ring type body comprises concentric upper tube body 3 and lower tube body 1, and air inlet 5 links to each other with lower tube body 1; Upper tube body 3 is communicated with through tube connector 4 with lower tube body 1, and the nominal diameter of upper tube body 3 is greater than the nominal diameter of lower tube body 1.
The set-up mode of the pore 2 on upper tube body 3 and the lower tube body 1 adopts following mode: like Fig. 3, Fig. 4 and shown in Figure 5; Several pores 2 of different-diameter evenly are provided with along normal direction positive direction, normal direction ± 30 ° direction, normal direction ± 60 ° direction and the normal direction ± 90 ° direction of the first half of upper tube body 3 and lower tube body 1; Promptly form the arrangement mode of seven circle pores 2 in the first half of upper tube body 3 and lower tube body 1, the formed circle of circle center line connecting of seven circle pores 2 is concentric.
According to the different processes needs, the diameter of above-mentioned pore 2 adopts 3～5mm, and the spacing between the adjacent pore 2 is 3～5cm.And the arrangement mode of the pore 2 of different-diameter on upper tube body 3 and lower tube body 1 can adopt following three kinds of forms: (1) is as shown in Figure 3, and the formed circle of circle center line connecting of the pore 7 that the pore 6 that every loop diameter is big and every loop diameter are little is concentric; (2) as shown in Figure 4, the pore 6 that diameter is big is serpentine at upper tube body 3 and the corresponding circumferencial direction in lower tube body 1 upper edge and arranges; (3) as shown in Figure 5, formed seven circles of circle center line connecting of every circle pore 2 are concentric in the seven circle pores 2, and the big pore 6 of diameter is " X " shape along the circumferencial direction of upper tube body 3 and lower tube body 1 and arranges.
