Description
Technical field
The present invention relates to a kind of Chu Droplets device, specifically a kind of for Phosphoric Acid Concentration process Chu Droplets device.
Background technology
In the process concentrated phosphoric acid,diluted, owing to being long continuous seepage, under high negative pressure, phosphoric acid can produce a large amount of containing P in system
2o
5mist, these mists can be carried secretly along with steam and fluoro-gas, cause a large amount of P
2o
5loss and waste, phosphorus yield reduce, and the fluosilicic acid simultaneously making tail desorption system produce is containing P
2o
5amount increases, and quality declines.Therefore demister device can be used in Phosphoric Acid Concentration production process to solve the problem.
Demister conventional is at present roughly divided into three kinds: inertia-type, centrifugal, miniflow formula.Inertia-type demister advantage is to install simple, and structure is simple and be easy to cleaning, but resistance is comparatively large, is not suitable for Phosphoric Acid Concentration production process and uses.
Centrifugal demister is divided into inner-rotary type and evolute.Evolute demister coefficient of purification is higher, relatively simple for structure, but crushing is comparatively large, must install on indirect steam pipeline.Inner-rotary type demister coefficient of purification and crushing smaller compared with evolute demister, be adapted at flash distillation indoor location.The flow rates demand of centrifugal demister to gas is higher, and be generally 11 ~ 23m/s under normal pressure, under vacuum condition, gas flow rate is generally 50m/s.And in Phosphoric Acid Concentration production process, the gas flow rate that flash chamber is discharged is less, generally only have 3 ~ 5m/s, therefore, centrifugal demister is also not suitable for using.
Screen type demister in miniflow formula demister is the most effective one of foam removal, miniflow formula demister compact conformation, and demist is effective, fluid resistance is little, if but be used in the evaporimeter easily producing fouling, and easily blocked, add cleaning frequency and have impact on the normal driving cycle.
Summary of the invention
The object of this invention is to provide and a kind ofly effectively can carry out gas-liquid separation for Phosphoric Acid Concentration process Chu Droplets device, the phosphorus yield in concentration process can be improved, the waste of the resource not only reduced, and the quality that can promote vent gas treatment byproduct fluosilicic acid.
The present invention is achieved in that and comprises sealed shell of tank, and above tank body, sidewall is provided with air inlet, and the symmetrical centre of air inlet is arranged along tank body tangential direction; Tank body lower sidewalls is provided with leakage fluid dram; Be provided with blast pipe in tank body, exhaust outlet is arranged on tank base, and the import of blast pipe is arranged on tank body centre and is positioned at above air inlet; Be provided with separated for tank inner chamber seal diaphragm below the inherent leakage fluid dram of tank body, dividing plate is to the downward-sloping setting in leakage fluid dram side.
Be arranged on by this Despumation device between flash chamber and fluorine absorber, the gas that flash chamber is discharged tangentially enters in tank body, containing P through air inlet
2o
5mist clash into inner tank wall under the influence of centrifugal force after broken and flow downward along inwall, realize gas-liquid separation, discharging through bottom leakage fluid dram is back in enrichment facility, gas along inwall twist inertia rise after again to intermediate flow, derived and delivered to fluorine absorber by tank body lower end through blast pipe downwards and process.Thus, this Chu Droplets device has the feature of inertia-type demister and centrifugal demister simultaneously.
Further, the import of blast pipe exceeds 1 ~ 1.5m than air inlet, and when making gas increase twist along inwall, liquid flows downward under gravity, thus can improve separative efficiency.
Preferably, the angle of inclination of described dividing plate, at 10 ° ~ 20 °, is beneficial to liquid and is rapidly to lower inflow leakage fluid dram and discharges, can reduce the secondary foaming of liquid under the impact of air-flow.
The present invention is separated in conjunction with centrifugal inner-rotary type demister centrifugal gas-liquid and the advantage of inertia exhaust of inertia-type demister, and air foam is separated comparatively thoroughly, makes the P of entrainment
2o
5come back in enrichment facility with liquid, decrease the waste of phosphor resource, and because the gas after separation is containing P
2o
5mist greatly reduce, the quality of follow-up vent gas treatment byproduct fluosilicic acid can be improved further.Secondly, air-flow is the flowing in inertia in tank body, and fluid resistance is little, and crushing is less; Moreover structure is simple and be easy to cleaning.
Accompanying drawing explanation
Fig. 1 is structure diagram of the present invention.
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described.Obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1 and Figure 2, the present invention includes sealed shell of tank 1, above tank body 1, sidewall is provided with air inlet 2, and the symmetrical centre of air inlet 2 is arranged along tank body 1 tangential direction; Tank body 1 lower sidewalls is provided with leakage fluid dram 3.Center in tank body 1 is vertically installed with blast pipe 4, and exhaust outlet 42 is arranged on bottom tank body 1, and the import 41 of blast pipe is positioned at above air inlet 2, and the import 41 of blast pipe cans be compared to air inlet 2 most and exceeds 1 ~ 1.5m.
Be provided with separated for tank body 1 inner chamber seal diaphragm 5 below the inherent leakage fluid dram of tank body 13, dividing plate 5 is that its angle of inclination is preferably at 10 ° ~ 20 ° to the downward-sloping setting in leakage fluid dram 3 side.
Its operation principle is as follows: be arranged on by this Despumation device between flash chamber and fluorine absorber, and the gas that flash chamber is discharged tangentially enters in tank body, containing P through air inlet
2o
5mist clash into inner tank wall under the influence of centrifugal force after broken and flow downward along inwall, realize gas-liquid separation, liquid is discharged through bottom leakage fluid dram and is back in enrichment facility.Gas along inwall twist inertia rise after again to intermediate flow, derived and delivered to fluorine absorber by tank body lower end through blast pipe downwards and process.
