Description

Technical Field

[0001] This invention relates to the field of activated carbon iodine adsorption value detection technology, specifically to an activated carbon iodine adsorption value detection device and method based on charge-coupled device. Background Technology

[0002] The iodine adsorption value of activated carbon is one of the important indicators for evaluating the adsorption performance of activated carbon. Traditional methods for testing the iodine adsorption value of activated carbon are complex and time-consuming, resulting in low detection efficiency and susceptibility to systematic and random errors.

[0003] Traditional activated carbon iodine adsorption methods require a professional laboratory and involve a series of operations, including manual or mechanical grinding of the activated carbon to be tested, drying in an electric heating box, iodine adsorption and filtration, and iodine titration.

[0004] The requirements for professional testing sites, professional experimental instruments, and professional personnel to operate these methods greatly limit the application of traditional methods in actual field testing.

[0005] Therefore, there is an urgent need to develop a device or method that can be operated by non-professionals and can quickly detect the iodine adsorption value of activated carbon on-site.

[0006] In recent years, charge-coupled device (CCD) image sensor technology has been widely used. It records images through photosensitive elements and converts them into electrical signals for analysis.

[0007] With the continuous development and popularization of image sensor technology, the method of using image sensors to detect the properties of materials has gradually attracted attention. The rapid detection technology based on charge-coupled device image sensors has been promoted in agriculture, environmental protection and other fields.

[0008] However, no image sensors have been found used to detect the iodine adsorption value of activated carbon. Image sensors are fast and accurate, enabling real-time data acquisition and processing, which is suitable for the need for rapid detection of iodine adsorption values ​​on activated carbon. They can greatly simplify the traditional activated carbon detection process and quickly obtain test results.

[0009] Therefore, it is of great significance to develop an intelligent device and method for rapid detection of iodine adsorption value on activated carbon based on a charge-coupled device image sensor.

[0010] First, it is challenging to use image sensors to acquire information about the adsorption on the sample surface and accurately measure the amount of adsorption.

[0011] Secondly, how to extract and analyze the characteristic parameters of sample adsorption using image processing algorithms, and then calculate the iodine adsorption value of activated carbon, is also an important issue.

[0012] Improving the sensitivity and accuracy of sensors to ensure the precision of detection results is also crucial. Therefore, this invention proposes for the first time an intelligent device and method for rapidly detecting the iodine adsorption value of activated carbon based on a charge-coupled device (CCD) image sensor, thereby improving detection efficiency and accuracy. Summary of the Invention
