Method for judging residual life of filter element of in-service gas filter and data acquisition system thereof

The invention discloses a method for judging the residual life of a filter element of an in-service gas filter and a data acquisition system thereof, which are used for analyzing the current use state of the filter element of the in-service gas filter by utilizing test data of the gas filter in a laboratory standard environment and data easily acquired on site. According to the method, the association relation between the accumulated flow and the pressure difference of the in-service filter element is generated, then the method for judging the accumulated flow when the filter element reaches the limit pressure difference is formed, the residual life of the gas filter element can be recognized earlier, and on the premise that the filter is not dismantled and only a small amount of historical data needs to be obtained, the residual life of the gas filter element can be recognized. The objective of predicting the life cycle of the filter element of the filter can be completed by detecting the service life of the
