Ammonia synthesis activity detection method based on shape recognition technology

Abstract

The invention discloses an ammonia synthesis activity detection method based on shape recognition technology. The detection method comprises main steps as follows: connecting each of an ammonia synthesis activity experimental device and a camera with intelligent equipment, and then placing a baffle plate with a hollow shape in the middle between the camera and an absorption indication bottle of the experimental device, and enabling the color of the baffle plate to be consistent with the color of a standard titrating solution in the absorption indication bottle before reaction; recording shapechange on the baffle plate through the camera after the ammonia synthesis experiment is started, and automatically reading out the residual gas volume, determined room temperature and atmosphere in the experimental device at this time through the intelligent equipment when a clear hollow shape occurs on the baffle plate; and finally detecting the ammonia synthesis activity according to the recorded data. Through the detection method disclosed by the invention, the disadvantage that the traditional manual operation is bad in repeatability is overcome, the accuracy is high, the price is low, andthe operation is convenient; and the ammonia synthesis detection method has the advantages of being simple in operation and lower in cost in comparison with the existing method based on color sensingtechnology.

Description

technical field [0001] The invention belongs to the technical field of chemical measurement, in particular to an ammonia synthesis activity detection method based on shape recognition technology. Background technique [0002] In the application of industrial ammonia synthesis, it is necessary to measure the activity of the catalyst, but the current mainstream method for the determination of its ammonia synthesis activity (such as, ammonia synthesis catalyst activity test method - the chemical industry standard of the People's Republic of China, HG / T3545-2014) By manually judging the end point of the color change of the indicator solution, and recording the aeration volume, and finally calculating the outlet ammonia volume fraction to analyze its catalytic activity. However, there are also some deficiencies in the method of determining the ammonia synthesis activity by manually judging the end point of the color change of the indicator solution: in terms of repeatability, the...

Problems solved by technology

However, there are also some deficiencies in the method of determining the ammonia synthesis activity by manually judging the end point of the color change of the indicator solution: in terms of repeatability, there are unavoidable human errors because different people have different judgments on the end point of color development; in terms of cost, the entire The determination of ammonia synthesis activity requires manual tracking and recording, which is time-consuming and labor-intensive, and the labor cost is high

These methods involve color or image acquisition, color image processing and analysis, etc. The process is more complicated and requires higher equipment

[0004] Therefore, it is necessary to develop a more simple and feasible intelligent detection technology for ammonia synthesis activity, which can overcome the shortcomings of poor repeatability of traditional manual operations, improve the accuracy of determining the end point of discoloration, reduce the labor intensity of operators, and reduce the labor intensity. cost and other characteristics
