Description
Technical field
The present invention relates to field of microbial culture technology, the tank pressure control device of specially a kind of parallel reactor.
Background technology
In microbial culture medium, dissolved oxygen concentration is an important finger for reflecting microbial cultivation process metabolic characteristics
Mark, is the result mutually balanced between oxygen supply condition and oxygen consumption condition.Wherein oxygen supply condition depends primarily on equipment in itself, including
Ventilation, stirring and tank pressure.For other gas solubilities, tank pressure and an important factor in order, tank pressure is except to gas
Solubility has a direct impact, and then oxyty is had an impact, and further metabolic process is had an impact.To parallel reaction
For device system, such as to be changed by dissolved oxygen concentration in incubation, so as to study the metabolic alterations difference between different tanks,
The stabilization for just needing to maintain each tank tank pressure as far as possible, to reduce the influence to dissolved oxygen concentration, makes experimental result with consistent with each other
The change of metabolic process can truly be reflected, improve the reliability of experimental result.
Due to the characteristic of microorganism, its incubation was both influenceed by external environmental condition, also interior in heredity by it
The influence of characteristic, its incubation can not repeat completely.Therefore, in its culture process optimization process, using parallel culture
Method, by eliminating system deviation, comparativity and the higher result of study of confidence level can be obtained.And present parallel reactor
Problems be present in the voltage-controlled system of tank：
It is the general small volume of each reactor tank in parallel reactor first, stability contorting tank pressure more difficult.And
If using miniature regulator to improve precision, although more stable reliable, due to more or less in incubation
It can be discharged with a small amount of liquid medium of exhaust clip band, the channel blockage of miniature regulator can be caused, and then pressure control can be caused to lose
Effect.
Next to that be usually that the tank pressure of each reactor tank is individually controlled in existing equipment, generally use detection tank
Pressure, the size of feedback regulation capacity and air inlet reach balance, to realize the regulation and control of tank pressure.This control device can typically produce
The mutual deviation of raw certain each reactor is systematic error, and the systematic error Producing reason is：Each tank sensor detection
The difference of the degree of accuracy；The difference of each tank transducer signal pick-up precision；The difference of each reactor control result；Each reactor is to tank
Press the asynchronous of the wave time of control result；Detected when needs go out gas in each reactor in exhaust regulating valve leading
When, it is drawn the flow capacity limited on reactor and interferes, influences tank pressure control stability, and this interference is with each anti-
Answer device circulating sampling and cause circulation to disturb.

Degree, just it is enough to ignore gas flow resistance and condensation fluid column pressure in pipeline, reaches the tank pressure of each tank and mutually balance unanimously.
And gas via each gas exhaust piping enter surge flask in, wherein entrainment with condensation drop can because flow velocity reduction rest on it is slow
Rush in bottle, can so ensure that the work of exhaust regulating valve in its Subsequent passes is unaffected.
It is to complete the control for several reactor tank tank pressures by an equipment and one group of control and detection device,
Device cost has not only been saved, observing and controlling points has been also greatly reduced, so as to reduce fault rate, reduces maintenance cost.
Preferably, secondary gas exhaust piping is further provided with the surge flask；The secondary gas exhaust piping is provided with manual bypass
Valve.So that when automatic control is broken down or flow is inadequate, manually bypass valve is adjusted manually.
Preferably, pressure relief pipe is further provided with the surge flask, the pressure relief pipe is provided with safety relief valve.With
The tank pressure control device tank of parallel reactor is avoided to press through height.
Preferably, the tank pressure control device of parallel reactor further comprises blowoff line, and the blowoff line is from described
The bottom of surge flask is led to outside the surge flask, and tapping valve is provided with the blowoff line.To condensate liquid etc. is timely
Discharge.
Specifically, the air inlet pipeline in each reactor tank is provided with inlet air flow gauge and check valve.To prevent gas
Alter.
Specifically, the pressure detection mechanism is mechanical pressure gauge or pressure sensor.
Specifically, the exhaust regulating valve can be mechanical counterbalance valve.

A kind of tank pressure control device of parallel reactor provided by the invention, it can bring following at least one beneficial to effect
Fruit：
1st, reactor tank is with surge flask UNICOM, and then coordinates pressure detection mechanism and exhaust regulating valve to be adjusted.
Because row buffering is entered in the exhaust for summarizing each reactor tank so that the fluctuating range of gas pressure reduces, while employs collection
Middle detection, the relative sensitivity for improving control, so as to lift overall control accuracy.
2nd, the asynchronous problem of wave time during solving when individually progress tank is voltage-controlled processed, and needing Tail gas measuring
When to each reactor tank exhaust cycle sampling cause the circulation to the voltage-controlled system of each tank to disturb.Even if tank pressure slightly fluctuates, each tank
It is synchronous fluctuation, i.e., parallel control is carried out to tank pressure, it is ensured that the uniformity changed between each reactor tank.
3rd, the gas exhaust piping of each reactor tank collects into buffer container, as long as pipeline is thick enough, keeps certain condensate drain
The gradient, just it is enough to ignore gas flow resistance and condensation fluid column pressure in pipeline, the tank pressure of each tank is reached mutually balance one
Cause.
4th, gas enters in surge flask via each gas exhaust piping, wherein entrainment can stop with the drop condensed because flow velocity reduces
Stay in surge flask, can so ensure that the work of exhaust regulating valve in its Subsequent passes is unaffected.
