Embodiment 1

[0023] Such as figure 1 As shown, the acid rain resistance performance detection device of the high-temperature corrosion inhibition layer of the present invention includes a horizontally placed storage board 1, on which a plurality of through slots 2 for placing test panels are arranged, and on the top of the storage board 1, two mounting plates are arranged. There is a first water tank 3 for acidic water, the first shower head 4 is communicated with the bottom of the first water tank 3, the nozzles of each first shower head 4 are covered with a plurality of through grooves 2, and the bottom of the storage board 1 is provided with a The second water tank 5 of neutral water, the top of the second water tank 5 is provided with a plurality of second shower heads 6, and the second shower heads 6 are positioned between the second water tank 5 and the storage board 1, the second shower heads 6 and the first shower heads 4 are opposite one by one, the distance from the opposite seco...

Embodiment 2

[0026] The object plate 1, the through groove 2, the first water tank 3, the first nozzle 4, the second water tank 5, and the second nozzle 6 are all installed in the sealed detection box 7, and the object plate 1 divides the detection box 7 into upper, upper, and lower. The next two independent sealed chamber. A first humidity sensor 8 is arranged in the sealed cavity below the shelf 1 , and a second humidity sensor 9 is arranged in the sealed cavity above the shelf 1 . The first humidity sensor 8 and the second humidity sensor 9 are connected to the same controller.

[0027] The detection box provides a sealed environment for the detection of corrosion inhibitors, which helps to discharge the influence of other components in the air on the corrosion inhibitors, and improves the accuracy of detection results; the first humidity sensor and the second humidity sensor are used for Detect that the humidity of the environment on the upper and lower sides of the same test board is...

Abstract

The invention discloses a detecting device for acid rain resistance of a high-temperature corrosion inhibition layer. The detecting device comprises a horizontally-arranged article placing board, wherein a plurality of through grooves for placing test boards are formed in the article placing board; two first water tanks for holding acidic water are arranged above the article placing board; a firstspray head is communicated to the lower part of each first water tank; a plurality of through grooves cover the lower part of a spray nozzle of each spray head; a second water tank for holding neutral water is arranged below the article placing board; a plurality of second spray heads are arranged above the second water tank and are positioned between the second water tank and the article placingboard; the second spray heads are in one-to-one correspondence to the first spray heads; the distance between each second spray head and the article placing board is equal to that between the corresponding first spray head opposite to the second spray head and the article placing board; the same through groove covers each second spray head and the first spray head opposite to the second spray head. According to the detecting device disclosed by the invention, the influence of ambient humidity is eliminated, and accuracy of the detection result for the acid rain resistance of a corrosion inhibitor is improved.

Description

technical field [0001] The invention relates to an acid rain detection device, in particular to a detection device for the acid rain resistance performance of a high-temperature corrosion inhibition layer. Background technique [0002] With the continuous improvement of the degree of industrialization and the extensive use of fossil fuels, the emission of SO2 and NOx into the atmosphere continues to increase, resulting in a continuous increase in the frequency, intensity and scope of acid rain. my country has become the third largest acid rain area after Europe and North America. . Acid rain is very harmful. In oil production sites, it will cause acid corrosion to oil production pipelines, drilling tools, drill bits and other equipment. [0003] At present, the acid rain resistance performance of corrosion inhibitors is generally tested by immersion or spraying. The immersion method is far from the actual natural environment, because acid rain in the natural environment wash...
