Abstract
An apparatus for evaluating a dried crystal error in a COdrying experiment comprises a heating jacket, a visual container, a weighing device, a transparent cover, a control apparatus, a vacuum pump, a damping table and a heating apparatus, and can accurately dry and weigh a rock sample subjected to a carbon dioxide drying effect experiment in the visual container, so that the crystal error caused by evaporation of a solution in the rock sample in the process is calculated. This apparatus provided by the present invention has high precision and simple operation, can well evaluate the crystal error caused by the saline solution retaining in the rock sample when the rock sample is directly dried in the carbon dioxide drying effect experiment, and can correct the results of the carbon dioxide drying effect experiment compared with the prior art, thereby obtaining accurate experiment results.
