Description
Technical field
The utility model relates to the gas barrier of fermentor tank, particularly the exhaust gas-liquid separation device of fermentor tank in the itaconic acid fermentation process.
Background technology
biological fermentation generally adopts the vertical mixing tank as fermentor tank, inlet pipe is arranged at the fermentor tank bottom, be responsible for passing into the sterile air that bacterial classification is breathed, gas exhaust duct is arranged at the top, the waste gas of being responsible for producing in fermenting process is discharged, gas exhaust duct is unimpeded all the time in whole fermenting process, base-material in biological fermentation process is generally the materials such as carbohydrate, viscosity is higher, when air flow does not mate with stirring, easily produce foam, the foam formation speed is exceedingly fast, as finding in time that not foam arrives the venting port position very soon, at this moment foam is mingled with fermented liquid and discharges from gas exhaust duct, the material phenomenon occurs to run.Not only pollute environment, and caused loss of material.
The utility model content
The purpose of this utility model is to overcome the problem that above-mentioned prior art exists, and a kind of easy methylene-succinic acid exhaust gas-liquid separation device is provided, by gas exhaust duct transformation is avoided the loss of material and the pollution of environment.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be:
Methylene-succinic acid exhaust gas-liquid separation device, comprise the main exhaust pipeline that is connected on the fermentation tank body, it is characterized in that, described main exhaust pipeline connects material collector and secondary material collector in turn, a described material collector inner top is provided with an air inlet cylindrical shell that is covered with pore, be a gas exhaust duct of material collector of connection and secondary material collector above an air inlet cylindrical shell, one time the material collector inner bottom part is communicated to the fermentation tank body through a reflux line; Described secondary material collector inner top is provided with the secondary air inlet cylindrical shell that is covered with pore, secondary air inlet cylindrical shell top connecting secondary gas exhaust duct, secondary material collector inner bottom part through the secondary back pipeline communication to the tank body that ferments.
Further program of the utility model can also be:
Described second exhaust pipe road is provided with the end valve, and the steam-pipe of carrying vapour valve is connected on the second exhaust pipe road.
The inner bottom part of a described material collector and secondary material collector is taper, and return line is connected to bores at the end.
in biological fermentation process, after material forms bubble, liquid level rises suddenly, gas-liquid mixture enters material collector one time by main exhaust, because the change in space is large, the power potential energy of mixture reduces, spouting of liquid is on barrel, form the flowing water shape and enter reflux line downwards one time, gas enters gas exhaust duct from heavy and light No. one time by an air inlet cylindrical shell, still be mingled with partially liq in gas this moment, at this moment mixture enters the secondary material collector, this moment, the power potential energy of mixture continued to reduce, liquid enters the secondary back pipeline downwards along this inner collector wall flowing water shape, gas discharges through the secondary exhaust pipeline by the secondary air inlet cylindrical shell.After fermentation is completed, close the end valve, pass into steam by steam-pipe, in order to the sterilization after fermentation ends.
The beneficial effects of the utility model are:
1, material collector and secondary material collector only are set, simple in structure, be easy to realize.
2, through material collector and secondary material collector, main exhaust pipeline expellant gas on the fermentation tank body is processed, avoided causing loss of material, also protected environment.
3, because the steam-pipe of carrying vapour valve is connected on the second exhaust pipe road, after fermentation is completed, close the end valve, pass into steam by steam-pipe, the sterilization in order to after fermentation ends makes technical process be tending towards reasonable.
Description of drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1 main exhaust, 2 material collectors, 3 reflux lines, 4 air inlet cylindrical shells, 5 secondary material collectors, 6 secondary back pipelines, 7 secondary exhaust pipelines, 8 steam-pipes, 9 end valves, No. 10 gas exhaust ducts, 11 steam valves, 12 fermentation tank bodies, 13 secondary air inlet cylindrical shells.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in Figure 1, methylene-succinic acid exhaust gas-liquid separation device comprises the main exhaust pipeline 1 that is connected on fermentation tank body 12.
Described main exhaust pipeline 1 connects material collector 2 and secondary material collector 5 in turn.
One time material collector 2 inner tops are provided with an air inlet cylindrical shell 4 that is covered with pore, the end of main exhaust pipeline 1 gos deep into the below to an air inlet cylindrical shell 4, air inlet cylindrical shell 4 top are communicated to the fermentation tank body for 10, the material collector inner bottom parts of a gas exhaust duct that connect material collector 2 and secondary material collector 5 through a reflux line 3.
The inner bottom part of a described material collector 2 and secondary material collector 5 is taper, and return line is connected to bores at the end.
Each vapor pipe stretches to material collector, stretching into sufficient length disconnects, utilize the material principle different from the gas deadweight, material is collected downwards along the collector barrel, gas continues to discharge by the air inlet cylindrical shell, one time material collection is often not thorough, collects so need to enter secondary material, and last gas discharges.
