Automatic sampling system and control method of fermentation tank
InactiveCN104845879AAchieve emptyingBioreactor/fermenter combinationsBiological substance pretreatmentsPulp and paper industryBottle
The invention discloses an automatic sampling system and a control method of a fermentation tank. In a sampling process, a sampling valve is controlled to be opened, a pipeline valve is controlled to be opened and a bidirectional sampling pump is controlled to be opened by a controller. When a fermentation liquor sample is detected by a liquid sensor, the controller starts timing and delays a certain time to control the sampling valve to be closed, and simultaneously controls a blowing pump and a blowing valve to be opened, and the sample in a delivery pipe is sent to a sampling pool by the sterile air through a sterile air pipe. When the fermentation liquor sample is detected by an electro-conductive liquid sensor in the sampling pool, the controller controls the bidirectional sampling pump to be closed and controls a waste solution valve to be opened, and the redundant fermentation liquor sample in the delivery pipe is discharged to a waste solution bottle through a waste solution pipeline. After the fermentation liquor sample is processed, the controller controls the waste solution valve to be opened and controls the bidirectional sampling pump to reversely rotate, and the fermentation liquor sample in the sampling pool is discharged to the waste solution bottle through the waste solution pipeline. The automatic sampling system is suitable for various fermentation sampling devices, various fermentation tanks can be automatically sampled, and thus an on-line analyzing system can be applied to various fermentation types.

According to the invention, pipelines behind cleaning circulating pumps of all membrane cleaning circulating systems communicate with each other, soa plurality of the cleaning circulating pumps can be used for pressurized cleaning of one membrane module, and thus, cleaning pressure with a larger selection range is provided in the process of cleaning one membrane module, the cleaning pressure is improved, and cleaning efficiency and cleaning effect are improved; the pipeline behind the cleaning circulating pump of the membrane cleaning circulating system positioned at the tail end of a liquid supply pipeline is connected with an inlet of a liquid supply tank, so emptying of the pipeline from the liquid supply tank to a cleaning circulatingtank is achieved; and discharged water is supplied to the liquid supply tank through the cleaning circulating pump, so emptying of the whole pipeline is achieved, the situation that residual cleaningliquid in the pipeline influences the temperature and pH value of cleaning liquid in a subsequent cleaning process is prevented, and therefore, membrane cleaning effect is improved.
