Development of Principle and Methodological Provisions for Installation Site and Design of Pressure Drop Sensors for Coarse and Fine Purification Filtering Cartridges Located in a Single Vessel of a Two-Stage Gas Filter

Abstract

The article is dedicated to the development of principles and methodological provisions for pressure drop sensors layout for coarse and fine purification filtering cartridges located in a two-stage gas filter vessel. It has been found out that static gas pressure in the lower part of the coarse and fine purification filtering cartridges is always greater than in the upper part. This conditions proportionately higher amount of flowing gas, and hence greater amount of solid particles deposited in the lower part of cylindrical filtering cartridges and, as a consequence, greater degree of filtering material contamination. Measuring pressure drop in the lower part of filtering cartridge, which is more clogged with solid particles, makes early signal at the operator console possible, which provides time for technical staff to urgently remove accumulated blockages from the coarse purification cartridge and replace the cylindrical fine purification filtering cartridges.These methodological provisions allow the possibility for reliable sensor design and precise determination of installation locations in filter parts designed for crude, coarsely purified and finely purified gas flow, which can be used within engineering practice.
