Abstract

A method and a device for determining the fault results of a built-in feeder. Filters that know the characteristics that have been revealed It consists of passing a feed stream through a filter (5) of known characteristics. Consideration of change in flow resistance of Filter feeder flow Both by continuous Or during And based on this information, the input error index (FFI) calculation characterizing the error of It also disclosed a method and equipment for verifying the operation of the filter system containing the sampling system parameter values at the selected location. Inside the filter system At the preset sampling rate Profile style creation Parameters from the parameters sampled at the specified intervals. And analysis Characteristic profile parameters In order to determine the correct operation of the filter system, one method and equipment for review was also disclosed. And control of the filter system On the basis of washing efficiency That method consists of determining the resistance. Review of the filtering elements used in the filtering system at the specified time during the system wash cycle by examining a number of operating parameters of the system, calculating the cleaning performance that shows the efficiency of the system wash cycle. Filtered using the considered resistance values And control of the filtering system That depends on the value of the calculated cleaning efficiency

Claims (2)

1. Method of determining the fault effect of the feed current of a filter having known characteristics includes the steps of i) through the feed current. Through one of the filters with known characteristics ii) determination of the change in resistance to the flow of the filter feeder, either continuously or over a period of time, and iii). feed fouling index, or FFI) that represent the fault nature of the filter feed stream. 2.
