Abstract

The invention discloses a control method for sulfuric acid leakage monitoring. The method comprises steps as follows: leaked acid receiving tapes are arranged at the parts requiring sulfuric acid monitoring; the structure of each leaked acid receiving tape is as follows: copper wires are laid on a substrate made of a thermoplastic resin material and coated with polyether-ether-ketone protecting layers; if the resistance values of the leaked acid receiving tapes change, sulfuric acid leakage alarm is given; and the stable resistance values are acquired after the resistance values of the leaked acid receiving tapes change, the specific sulfuric acid leakage position is obtained according to the relationship among acquired stable resistance values, the section areas of the copper wires and the electrical resistivity of the copper wires before leakage, and a notification message is sent. According to the method and the device, the problems that micro-leakage of sulfuric acid cannot be monitored at present and the leakage position cannot be positioned are solved.

Description

technical field [0001] The invention relates to the technical field of automatic monitoring, in particular to a control method and device for sulfuric acid leakage monitoring. Background technique [0002] Sulfuric acid is an important industrial raw material, and pipeline transportation is a commonly used method of sulfuric acid transportation. Once the sulfuric acid pipeline leaks, it will not only cause waste of sulfuric acid, but more seriously, it will cause great danger in the surrounding environment, and even endanger personal safety. At present, most of the sulfuric acid delivery pipelines are not equipped with automatic leakage monitoring devices, relying on manual inspections, leaks cannot be found in time, and small leaks are easily missed, which wastes manpower. At present, some pipelines use the negative pressure wave method for online monitoring, and use the pressure change in the pipeline to monitor the sulfuric acid leakage when the sulfuric acid leaks. Howe...
