Abstract

The utility model relates to a centrifugal turbine liquid-gas separator, which comprises a turbine fixed vane wheel, an inner cylinder and a current regulator. The outer circumference of the turbine fixed vane wheel and the inner wall of a cylinder are cooperatively fixed, the cylinder is divided into an upper part and a lower part, the central hole of the cylinder and the lower end of an exhaust pipe are fixedly connected. Channels among the blades of the turbine fixed vane wheel causes the upper and lower parts of the cylinder to be communicated. The lower end of the turbine fixed vane wheel is fixedly connected with the inner cylinder, an annular gap is composed between the outer wall of the inner cylinder and the inner wall of a cylinder, and the lower end of the cylinder is fixedly provided with the current regulator, which causes the separation efficiency of the utility model especially the separation efficiency of liquid-gas mixture mixed with a great deal of foam to be enhanced.

Description

A kind of centrifugal turbine gas liquid/gas separator

The utility model relates to a kind of centrifugal gas-liquid separator, especially a kind ofly is used for the centrifugal turbine gas liquid/gas separator that fermentation industry fermentation tank blast pipe is received zymotic fluid last time.

In fermentation industry, contain saturated vapor in the fermentation tank exhaust, wherein also be entrained with many zymotic fluid hanging drops, produce a large amount of foams in addition in the sweat sometimes suddenly, these situations all can cause bulk fermentation liquid loss in the sweat.

In China's fermentation industry, the fermentation tank exhaust does not generally add processing at present, and indivedual factories adopt cyclone that exhaust is handled, and it separates the efficient variation huge because of deflation rate produces of gas-liquid, and is not good to the separating effect of a large amount of foam sample exhaust.Zymotic fluid runs off in a large number during for fear of the fermentation tank exhaust, and the normal way that reduces the fermentation tank useful load that adopts causes the useful load of a fermentation tank only to account for about seventy percent of fermentation tank cubical content, makes output descend, and cost improves.

The purpose of this utility model is to improve the deficiencies in the prior art, provides a kind of to the high centrifugal turbine gas liquid/gas separator of a large amount of foam sample gas-liquid mixture separative efficiencies, to reduce the loss of zymotic fluid in the fermentation tank exhaust, improves output, reduces cost.

The purpose of this utility model is achieved in that centrifugal turbine gas liquid/gas separator comprises cylindrical shell, air inlet pipe and blast pipe, air inlet pipe is located on the barrel of cylindrical shell upper end, blast pipe inserts inner barrel by the upper top of cylindrical shell, the lower end of blast pipe is lower than the air inlet on the barrel, it also comprises fixedly impeller of turbine, inner core and flow straightener, the turbine fixedly excircle and the cylinder inboard wall of impeller closely cooperates fixing, cylindrical shell is divided into, following two parts, its centre bore and blast pipe lower end are airtight affixed, and the turbine fixedly passage between the blade of impeller is linked up on the cylindrical shell, following two parts; At the fixing affixed inner core in lower end of impeller of turbine, the inner core external diameter constitutes an annular gap---vortex tube less than the fixing root circle of impeller of turbine between inner tank theca and the cylinder inboard wall, and the length of vortex tube is less than the length of cylindrical shell lower part; Set firmly the flow straightener of the fluid of a screw blocked of in cylindrical shell, stretching in the lower end of cylindrical shell, its effect is that the gas-liquid mixed logistics of downward screw is cut off, the surface that liquid contacts flow straightener loses kinetic energy, and is dirty along its surface, and gas is then upwards overflowed from exhaust outlet; Cylindrical shell be return duct bottom, return duct connects fermentation tank, and the liquid of separating is returned fermentation tank.

In use, the gas-liquid mixed shape fermentation tank exhaust that contains a large amount of foams enters the top of this separator cylindrical shell by air inlet pipe with certain speed, fixedly make the gas rotation in the leaf road of impeller by turbine, the gap spiral that enters between cylindrical shell and the inner core advances, in this process, the foam fragmentation, liquid phase is bigger because of density, and is adherent to dirty; Gas phase is less because of density, relatively near the inboard in difficult gap, arrives the cylindrical shell bottom and comes out from described gap, and its screw is subjected to overflow from blast pipe after the braking of flow straightener, and the liquid of separating returns fermentation tank by return line flow.

The centrifugal turbine gas liquid/gas separator that the utility model provides is owing to increased fixedly impeller of turbine; inner core and flow straightener; make its separative efficiency; especially the separative efficiency to the gas-liquid mixture that contains a large amount of foams improves greatly; handle the discharge gas of fermentation tank with this separator; can reduce the loss of zymotic fluid significantly; therefore; just can improve the useful load of fermentation tank; reduce the consumption of defomaing agent,, reduce cost to improve output; simultaneously; some bacterial classification has pollution to environment, will carry out the degerming process to the fermentation tank exhaust usually, uses this efficient cyclone that the minimizing of environmental protection and expenses of environmental protection is had great role.

The utility model is described in further detail below by drawings and Examples.

Embodiment:

As shown in Figure 1, set firmly an air inlet pipe 2 on the barrel of the upper end of cylindrical shell 1, put in cylindrical shell at the top of cylindrical shell 1 blast pipe 3, the lower port of blast pipe 3 is lower than the air inlet on the barrel.Interference fit sets firmly fixedly impeller 4 of turbine in cylindrical shell, and its center is porose, and is airtight affixed with the lower port of blast pipe 2.Turbine fixedly the blade of the lower surface of impeller 4 manage 5 less than the sealing of the circumference place at impeller root circle place in affixed, between interior pipe 5 outer walls and cylindrical shell 1 inwall gap is arranged---vortex tube 6, its length is less than the length of cylindrical shell bottom.Set firmly a flow straightener 7 in cylindrical shell 1 interior lower end, cylindrical shell 1 is return duct 8 bottom.
