Abstract
The invention discloses an online volatile fatty acid (VFA) content monitoring system and method. The online monitoring system comprises a fermentation tank, a pump, a filtering device, a VFA content detector, a data transmission terminal and an automatic control system, wherein one end of the filtering device is connected with the fermentation tank through the pump, and the other end of the filtering device is connected with the VFA content detector; the VFA content detector is connected with the data transmission terminal; the data transmission terminal is connected with the automatic control system in a wireless or wired mode. The system and method have the advantage of high real-time property and play a decisive role in the aspect of monitoring the fermentation process.
Description
Technical field
The present invention relates to anaerobic fermentation of organisms technical field, be specifically related to a kind of VFA content on-line monitoring system and method thereof.
Background technology
VFA, volatile fatty acid, is the intermediate product that anaerobic fermentation of organisms generates methane, monitoring VFA content can directly judge raw material state, precognition aerogenesis situation.
More conventional monitoring method is indirect measurement at present, as measured pH value.The PH meter indirect method of measurement has very large time delay, can not the current fermentation appearance of real time reaction, and the maintenance workload of PH meter is large.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, and technical matters to be solved is for providing a kind of VFA content on-line monitoring system and method thereof.
To achieve these goals, the present invention adopts following technical scheme:
A kind of VFA content on-line monitoring system, comprise fermentation tank, pump, filtration unit, VFA content detector, data transmitting terminal and automation control system, described filtration unit one end is connected with fermentation tank by pump, the other end is connected with VFA content detector, and described VFA content detector is connected with data transmitting terminal, and described data transmitting terminal is connected with automation control system by wireless or wired mode.
Preferably, described data transmitting terminal is to be arranged on described VFA content detector inside or outside GPRS transmitting terminal.
Preferably, described automation control system is DCS control system.
A VFA content on-line monitoring method, comprises following several step:
(1) by pump, from fermentation tank, taken out and detect sample;
(2) through filtration unit impurity screening, send into VFA content detector;
(3) VFA content detector detects in real time, detects data and is sent to automation control system by transmitting terminal.
The present invention compares with conventional P H detection technique, and the present invention is real-time, at sweat
There is conclusive effect monitoring aspect.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is elaborated:
Fig. 1 is the module diagram of VFA content on-line monitoring system in the present invention.
Embodiment
Native system comprises fermentation tank, pump, filtration unit, VFA content detector, data transmitting terminal and automation control system, filtration unit one end is connected with fermentation tank by pump, the other end is connected with VFA content detector, VFA content detector is connected with data transmitting terminal, and data transmitting terminal is connected with automation control system by wireless or wired mode.Can adopt GPRS means to send data to automation control system as DCS control system, also can directly between VFA content detector and automation control system, set up link connection.
In anaerobic fermentation of organisms process, by pump, from fermentation tank, take out and detect sample, then pass through filtration unit impurity screening, send into VFA content detector and detect in real time, the VFA content value detecting is sent to automation control system by GPRS or data link.
