The plurality of advantages such as product is big, equipment volume is small, filter efficiency is high, the pressure loss is low are gradually favored by fermentation industry.And
Traditional air cleaning system uses cotton as filter medium more, because its pressure drop is big, operating cost is high and it is complicated to change
The shortcomings of, seriously constrain the development of enterprise.
The content of the invention
It is an object of the invention to provide a kind of filter method based on film device, present system intelligent and safe, carries out
Automated condtrol, filter efficiency is improved, reduce energy waste.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of filter method based on film device, this method comprise the following steps：
S1, infrared receiving device are obtained in air and sent after solid suspension concentration to constituent analysis unit；
Pernicious gas detection module obtains pernicious gas content and sent to constituent analysis unit；
S2, component analysis module obtain pollutant concentration after with standard solid concentration ratio pair, if pollutant concentration be less than or
Equal to standard solid thing concentration, then S3 is performed, otherwise performs S4；
S3, component analysis module send again detection signal to pernicious gas detection module and infrared detection module, fingerprint identification module；
Control parameter that S4, component analysis module ergodic data library lookup associate with pollutant concentration is simultaneously sent to membrane filtration
Unit.
Further, into it is described divide in analytic unit be preset with standard solid thing concentration.
Further, standard solid concentration includes standard solid state concentration of suspension and standard harmful gas concentration.
Beneficial effects of the present invention：
The invention discloses a kind of filter method based on film device, detects pernicious gas by gas sensor, passes through
Solid suspension concentration in infrared facility detection air, filtering repeatedly is carried out to the pollutant concentration in gas until air quality
It is up to standard, present system intelligent and safe, Automated condtrol is carried out, improve filter efficiency, reduce energy waste.
