Problems solved by technology

[0003] Furthermore, during the use of the online analysis and preprocessing system, it is often necessary to collect data such as temperature, pressure, and flow in order to grasp the status of the analyzed sample in real time. The traditional method is to collect on-site data manually, which is not only labor-intensive, Moreover, the environmental conditions at the device site are relatively harsh and complex, and there are certain safety risks. Therefore, a preprocessing system capable of intelligent online data acquisition and control is needed.

Abstract

The invention discloses an intelligent online analysis pretreatment system, which comprises a sample large reflux inlet and a sample large reflux outlet, wherein a sample inlet cut-off valve and an online self-cleaning bypass filter are arranged downstream of the sample large reflux inlet; the online self-cleaning bypass filter comprises a first inlet, a first outlet and a bypass outlet; an onlinerotary centrifugal filter is arranged downstream of the bypass outlet; an air cooler is arranged downstream of the online rotary centrifugal filter; and the intelligent online analysis pretreatment system further comprises a PLC control system. The intelligent online analysis pretreatment system has the following advantages: a large reflux structure is adopted, sample flow is unimpeded, samplingis rapid and timely, the automatic filter cleaning function can be realized, maintenance is free, real-time collection and intelligent control of temperature, pressure and flow parameters of online analyzed samples can be preformed, and the intelligent degree is high.

Description

Technical field [0001] The invention relates to an online analysis system, more specifically, an intelligent online analysis preprocessing system. Background technique [0002] There will be more or less particulate matter and impurities in the sampling samples of the online analysis system. At present, the more common method is to use a straight-through filter to filter the particulate matter and impurities. Because the direct-pass filter has a single-in-single-out structure, the filtered particles and impurities cannot be discharged in time, which may cause blockage of the pipeline or frequent cleaning and replacement. This not only limits the filtration accuracy of the sample (not less than 100μm), but also Greatly increase the amount of maintenance. Therefore, a filtration system with high filtration accuracy and maintenance-free is needed to replace the traditional filter. [0003] In addition, the online analysis preprocessing system often needs to collect data such as temp...
