Embodiment

[0038] Embodiment: the chassis 8 is made of aluminum, the partition 5 is made of aluminum plate, the filter 2 is made of a blade cyclone water separator, and the electric heating belt 4 is a commercially available AC 220V power supply, self-limiting temperature type (its surface temperature is not greater than 65 ℃) electric heating band, and the gas sensor 6 is a non-dispersive infrared carbon dioxide sensor and an electrochemical oxygen sensor. The signal processing unit 7 includes a power supply, an interface circuit, an A / D converter, a microprocessor, a display unit and a communication unit.

[0039]As shown in FIG. 1 , the partition 5 divides the case 8 into two parts, the sampling chamber and the detection chamber. There are two air holes on the dividing plate 5 . The electric heating belt 4 is evenly laid in the sampling chamber. One end of the inlet pipe 1 is connected to the exhaust port of the fermenter, and the other end is connected to the filter 2 in the rod ch...

Abstract

The invention discloses an integrated multi-component fermentation tail gas on-line detection device. It has simple structure, strong practicability, long-term online operation, completely solves the influence of exhaust humidity on detection and the problem of gas Louis blockage, and can complete the online detection of multiple components of exhaust gas at the same time. Its structure is as follows: it includes a chassis, and the chassis is divided into at least two relatively independent spaces, at least one of which is a sampling chamber and a detection chamber; a heating device is installed in the sampling chamber, and a gas detection device is installed in the detection chamber; the sampling chamber There is at least one air hole communicating with the detection chamber.

Description

technical field [0001] The invention discloses an integrated multi-component fermentation tail gas on-line detection device, which belongs to the technical field of fermentation tail gas detection manufacturing technology. Background technique [0002] In modern biotechnology processes, the optimization and control of fermentation and cell culture largely depends directly on its detection methods. Tail gas analysis can not only effectively optimize the biological process, but also avoid direct detection of bacteria contamination and other adverse effects on the fermentation process caused by the fermentation broth. Therefore, more and more attention has been paid to the application of online detection of tail gas in the fields of fermentation and cell culture. [0003] The tail gas discharged from the exhaust port of the fermentation tank during the fermentation process has a temperature of 27-37°C, a humidity of 100%, and a pressure of less than 0.05MPa. The main component...
