Supercritical carbon dioxide drying device

Abstract

The invention relates to the technical field of supercritical drying equipment, and discloses a supercritical carbon dioxide drying device which comprises a storage tank, a high-pressure pump, a drying heater and a drying kettle which are sequentially communicated through pipelines, and further comprises an identification detection module and a control module. The high-pressure pump, the drying heater and the identification detection module are electrically connected with the control module; the recognition and detection module is used for detecting the states of CO2 and materials and uploading the states to the control module; and the control module is used for analyzing the state information of the CO2 and the drying material and adjusting the drying device. The state of the drying process is detected through intelligent control, automatic adjustment is carried out, the dependence of the device operation process on professional technicians is reduced, intelligent data analysis response is rapid, problems are found in time, and tedious manual operation is avoided through automatic adjustment.

Description

technical field [0001] The invention relates to the technical field of supercritical drying equipment, in particular to a supercritical carbon dioxide drying device. Background technique [0002] Supercritical drying technology is a new chemical technology developed in recent years. Commonly used drying techniques such as normal temperature drying and baking drying often inevitably lead to material agglomeration during the drying process, resulting in coarser material base particles, a sharp decrease in specific surface area, and a large reduction in pores. The acquisition and preparation of high specific surface materials are extremely unfavorable; supercritical drying technology is drying under the critical and critical pressure conditions of the drying medium, which can avoid the shrinkage and fragmentation of the material during the drying process, thereby maintaining the original structure of the material And state, to prevent the agglomeration and condensation of prim...

AI Technical Summary

Problems solved by technology

The current supercritical carbon dioxide drying device and its use mode have the following problems: 1. It relies too much on the experience of technicians, and professional technicians cannot be separated from the on-site operation process, otherwise it is difficult to ensure normal operation

2. The change of the value in the drying process requires manual judgment and adjustment, and the response is not timely enough

3. The adjustment process of the device requires manual operation, which is time-consuming and labor-intensive
