Long distance concentrated sulphuric acid pipe leakage monitoring method

Abstract

The invention relates to a long distance concentrated sulphuric acid pipe leakage monitoring method, including that a cable and a cable fault monitor are utilized to monitor leakage state and leakage position of concentrated sulphuric acid pipe. The method is characterized in that the cable is an acid sensitive one with dressing made by polyether-ether-ketone PEEK material, adapts to water, alkali or mixture thereof and multiple mediums and is sensitive to concentrated sulphuric acid only, the acid sensitive cable is parallelly paved at the bottom of pipe along the whole course of concentrated sulphuric acid pipe, one end of the acid sensitive cable is connected on to the cable fault monitor, concentrated sulphuric acid leakage is monitored in real time, and the cable fault monitor automatically alarms once pipe leakage happens and provides the position of leakage point. The invention has the advantages that monitoring distance is long, single section longest monitoring distance can reach 30km, the method is heat resistant and can be resistant to high temperature of 250 DEG C for a long time, insulating property is good, structure is simple, use convenience is achieved, cost is low, no danger is produced, and online monitoring, leakage alarming and leakage positioning can be realized, and the invention is widely applied in long distance concentrated sulphuric acid pipe leakage monitoring.

Description

1. Technical field [0001] The invention relates to a method for monitoring the leakage of a sulfuric acid pipeline, in particular to a method for monitoring the leakage of a long-distance concentrated sulfuric acid pipeline. 2. Background technology [0002] As we all know, concentrated sulfuric acid is an extremely dangerous chemical medium. Once the concentrated sulfuric acid pipeline leaks, it may cause serious consequences. For the monitoring of concentrated sulfuric acid pipeline leakage, there is currently only the TT7000 induction cable produced by Tyco Thermal Control Company in the market, which can be specially used for the leakage monitoring of concentrated sulfuric acid, but the longest single-segment length is only 300 meters, and the price is expensive , more than 1,000 yuan per meter. 3. Contents of the invention [0003] The purpose of the present invention is to provide a long-distance concentrated sulfuric acid pipeline leakage monitoring method, using ...
