Description

A kind of gas-liquid separator

Technical field

The utility model relates to a kind of gas-liquid separator, especially a kind of separator that is applied to the fermentation tail gas gas-liquid separation.

Background technology

Aerobic fermentation needs oxygen, and oxygen is mainly derived from compressed air, for satisfying the fermentation needs, must feed a large amount of aseptic compressed airs constantly to fermentation tank.The problem of Chan Shenging is thereupon, and during the fermentation, fermentation tank exhaust (tail gas) is accompanied by a large amount of liquid foam entrainments, escapes with the form of foam, and wastes material, influence production.The foam center is air or other secondary gas that ferments, and the outsourcing liquid film includes fermentation medium and microbial cells, metabolite etc. in the liquid film, so fermentation tail gas is the gas-liquid-solid three-phase mixture.In order to reclaim culture medium and the tunning in the tail gas, simultaneously for reducing the pollution to production environment and atmosphere, tail gas must carry out gas-liquid separation to be handled.

Initial fermentation tail gas gas-liquid separation equipment is traditional cyclone separator, and it is simple in structure, but the separating effect instability when the variation of fermentation air quantity, foam peak, still has bulk fermentation liquid to escape; And often make fermentation dye assorted bacterium, when serious even midway tank switching is produced failure.Utility model 94224688.8 is efficiently revolved and is hit separator, has solved this problem preferably, and its separative efficiency is high and stable, can adapt to the significantly variation of fermentation different times air quantity, has replaced traditional cyclone separator in actual production, by popularization and application.But go back defectiveness on its structure, cause when the fermentation of some thickness culture mediums or adopt during the environment sensitive type microbial fermentation produces, can't thoroughly solve the microbiological contamination problem.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of suitable fermenting and producing, follow-on gas-liquid separator at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of gas-liquid separator, comprise the separator cylindrical shell and be arranged on the liquid outlet tube of separator cylindrical shell bottom and the mixture intake pipe of top side, it is characterized in that: escape pipe is arranged on the middle upper end of the inside of separator cylindrical shell, there is a gas outlet tube escape pipe upper end, the built-in air deflector in separator cylindrical shell top, separator cylindrical shell bottom is built-in with flow straightener.

As improvement, described mixture intake pipe is a reducing pipe, and its top flushes with described separator cylindrical shell top highest point.

As improvement, the top of described separator cylindrical shell is the curved surface of an inclination, and center of surface section bus and inlet tube straight section are tangent.

As improvement, reducing joint is arranged at described separator cylindrical shell top, realizes reducing by the conical surface transition section.

As improvement, described escape pipe respectively has reducing joint and reducer at the air deflector above-below direction, and top is the conical surface that dwindles, and the reverse cone that the bottom is a pair of expansion, dwindle is formed.

As improvement, described air deflector is to lay out the tracheae periphery by some with the inclination angle blade ring, with uniform the forming of certain clearance stack.

As improvement, described flow straightener center is a cylinder, and the cylinder periphery is welded with the some plate washers that radially distribute.

Compared with prior art, advantage of the present utility model is: a kind of gas-liquid separator, and its structure is more suitable for the characteristics of fermentation industry, and no matter fermentation broth viscosity size or produce the sensitiveness of bacterium to environment all is difficult for microbiological contamination, produces stable; Its structure more helps the separation of gas-liquid mixture, in the scope that air quantity significantly changes, has stable efficient separative efficiency, can reduce material loss, improve output; Its structure more helps reducing to ferment the exhaust resistance loss, reduces the aseptic compressed air energy consumption.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Anticipate as Figure 1-3, a kind of gas-liquid separator, comprise separator cylindrical shell 7, mixture intake pipe 1, mixture intake pipe 1 is a reducing pipe, its top flushes with separator cylindrical shell 7 top highest points, the top of separator cylindrical shell 7 is curved surfaces of an inclination, and center of surface section bus and mixture intake pipe 1 straight section are tangent, and the mixture air-flow can turn to after advancing bump smoothly, make separator cylindrical shell 7 upper spaces be difficult for buildup, the dead angle of no sterilization; The built-in escape pipe 6 in separator cylindrical shell 7 middle and upper parts, there is a gas outlet tube b escape pipe 6 upper ends; The built-in air deflector 4 in separator cylindrical shell 7 tops, air deflector 4 be by some with inclination angle blade 13 around escape pipe 6 peripheries, with uniform the forming of certain clearance stack, the blade 13 of air deflector 4 can be the plane also can be curved surface; Escape pipe 6 respectively has reducing joint 10 and one reducer 5 at air deflector 4 above-below directions, top is the conical surface that dwindles, the reducer 5 that the reverse cone that the bottom is a pair of expansion, dwindle is formed, air-flow is through this reducer 5, more help stablizing eddy flow, also help increasing the time of staying, improve separative efficiency; One reducing joint 3 is arranged at separator cylindrical shell 7 tops, and respective inner escape pipe 6 also has reducing joint 10, forms the annular space of an inclination, and gas is changed direction through this space; Separator cylindrical shell 7 bottoms reach and be provided with flow straightener 8 below air deflectors 4, flow straightener 8 centers are a cylinder 12, cylinder 12 peripheries are welded with the some plate washers that radially distribute 11, the plane of plate washer 11 can adopt that a right angle is trapezoidal also can to adopt parallelogram in it, but adopt right-angled trapezium more to help eliminating the gas phase vortex, make the liquid-solid phase of having separated be difficult for being carried secretly once more, improve separative efficiency by exit flow; Separator cylindrical shell 7 bottoms are provided with a liquid outlet tube 9.

Its operation principle is: gas-liquid mixture enters from import a, poly-through the convergent tube bank, produce the reinforcement impact effects in escape pipe 6 external wall of upper portion, cause lather collapse in the mixture, core foam gas is overflowed, separator cylindrical shell 7 tops are skewed curved surfaces, its peak flushes with mixture intake pipe 1 high point, so the mixture air-flow can turn to after advancing bump smoothly, air-flow is changed direction through the annular space that tilts, import air deflector 4, during through air deflector 4, the mixture air-flow is shunted, the forcibly changing direction, formation is the eddy flow rapidly downwards at center with escape pipe 6, when air-flow passes through the reducer of being made up of the reverse conical surface of two joints 5, stablize eddy flow, increase the time of staying, improve separative efficiency, the mixture air-flow in escape pipe reducer 5 peripheral following cylinder spaces through repeatedly rotating, produce the effect of centrifugation, liquid-solid phase is downward along separator cylindrical shell 7 inwalls, discharges (can still introduce fermentation tank inside) from outlet c, and gas phase runs into flow straightener 8 in the process that is rotated down, vortex is eliminated, under the influence of pressure reduction, the gas baffling after the separation enters escape pipe 6 inside, discharges from gas outlet tube b.
