Description

technical field [0001] The invention relates to the field of industrial production, in particular to a non-contact gas leakage detection system. Background technique [0002] At present, natural gas in production and living places such as gas stations is usually stored in horizontal storage tanks. Generally, the pressure of natural gas in horizontal storage tanks is more than ten atmospheres, and the natural gas stored in them is also corrosive to a certain extent. , such a horizontal storage tank is in a complex physical and chemical environment, and all structural performance indicators must meet higher requirements, so it is particularly important for the structural detection and protection of horizontal storage tanks. [0003] The gas stored in the horizontal storage tank is generally flammable and toxic. If the operation is improper or the management facilities and equipment are aging or malfunctioning, the high-pressure flammable gas inside may easily leak and cause a ...

Problems solved by technology

However, the contact gas detection sensor has the following disadvantages. 1. The gas detection sensor is directly placed on the surface of the storage tank. Most of the gas detection sensors inevitably destroy the protective coating on the surface of the storage tank. The direct impact of this system is The structure of the storage tank around the gas detection sensor is very easy to interact with the corrosion factors of the air; 2. The properties of the gas detection sensor directly in contact with the storage tank structure are quite different from the material properties of the storage tank itself, resulting in the gas detection sensor and the storage tank The surface tissue has a large electrode potential, and the electrochemical corrosion on the surface of the storage tank greatly weakens the safety performance of the storage tank

In order to realize the precise positioning of the gas leakage point, the effective way is to increase the number of gas detectors. Combined with the above two aspects, the traditional contact gas leakage detection system has a greater impact on the damage of the storage tank, which not only reduces The service life of the storage tank is shortened, and the probability of safety accidents is also increased to a certain extent.
