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

Embodiment 1

[0031] Such as figure 1 As shown, a supercritical carbon dioxide drying device according to an embodiment of the present invention includes a condenser 5, a storage tank 1, a high-pressure pump 2, a drying heater 3, a drying kettle 4, an identification and detection module, and a control module.

[0032] Such as figure 2 As shown, a kind of supercritical carbon dioxide drying device of the present embodiment, each component is connected in pipelines in sequence according to the order of the condenser 5, the storage tank 1, the high-pressure pump 2, the drying heater 3, and the drying kettle 4, and the drying kettle 4 of the present embodiment is There are three, and each drying tank 4 is connected in parallel, and the CO2 replenisher 7 is connected between the filter 6 and the condenser 5 through a pipeline. Each drying kettle 4 is provided with an automatic pressure regulating valve. When the pressure in the drying kettle 4 is excessive, the automatic pressure regulating va...

Embodiment 2

[0049] In addition to the content of the first embodiment, the second embodiment also includes:

[0050] The supercritical carbon dioxide drying device in this embodiment further includes a parameter analysis module, which is used to analyze whether the parameters adjusted by the supercritical carbon dioxide drying device are correct, and send the analysis result to the host.

[0051] The control module controls and adjusts the power and running time of the condenser 5, so that the pressure of the liquid CO2 in the storage tank 1 is about 9 MPa, and the temperature is about 20 degrees. Or control and adjust the pressure of the high-pressure pump 2 and the heating of the drying heater 3, so that the CO2 phase changes into a supercritical state. When encountering the situation that the control module cannot adjust the CO2 to the required state, it may be that the parameters of the drying device have not been adjusted in place, causing the control module to turn the condenser 5 o...

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...
