Method and system for monitoring the technical condition and leakproofness of storage tank bottoms, preferably the tank group, using the acoustic emission (AE), as the protection against penetration of petroleum and/or chemical products to soil and underground and surface waters

摘要

method and system for monitoring the condition and integrity den storage tanks, in particular tanks using acoustic emission group, as a safeguard against inputs of petroleum products and / or chemicals to the soil and groundwater and surface this is thatthat waves generated by sources of ae with dna (20) storage tank (19) monitored the tanker, are processed by the ae sensors isas3 (17) mounted on the container wall (19) into electrical signals, which are sent via coaxial oil pipe (16) by an electrically insulated protective barriers siso3 (15),placed in enclosures hiso3 (14) and on through the coaxial pipe (13) for measuring asip cards - 2 (12) of the measurement system amsy - 6 (10). successively followed by recording and archiving ae measurement data, in order to further processing, analysis, classification and visualization.but at the same time are monitored environmental conditions (26) and performance (29), which leads to the detection of ae signals indicating the occurrence of leakage and / or increased activity of corrosive material processes in dna and / or occurrence of damage kompo coatings zytowej dna (20) and alerting service staff of such events (5).the system contains multi channel acoustic emission system (10), together with ae sensors (17) and electrically insulated from the protective barrier (15) circuit measuring zones explosion hazards and safety zone, with both ae sensors (17) and a barrier (15) are intended to work in the risk of explosion of the atex zones certificate or equivalent.where the elements working directly in the explosion hazards in storage tank (19), sensors (17) with uziemieniem ae and conductors of circular olejoodpornymi rg058 t1 / 50 (16). with part of the measurement system from siso3 barriers (15) sensor (17) isas3 works under low and acceptable ranges for the risk zones, respectively, the supply voltage.further elements of the measuring system is rg058 coaxial conductors (13), measuring system, ae amsy - 6 (10) of the measuring asip cards - 2 (12), are already in the zone not explosive atmosphere (34), a measuring system, ae amsy - 6 (10) is operated with jednofazowego voltage source, support with special internal power supply.in addition, the bottom storage tank (19) are covered with a certified antyelektrostatycznym laminate (20) a simple or other equivalent certified antyelektrostatycznym boosted and a sealed cover.
