Higher efficiency, lower energy consumption and less pollution are become more and more important in chemical engineering. Post-process is one of the key parts for producing chemical productions. Thus, we develop a novel device, Chemical Post-Processing Integrated Equipment (CPPIE), which can deal with crystallization, filtration, washing and drying in the same tank by changing the position of it. Without the transfer during these processes, CPPIE have meaningful advantages compared to conventional devices. In this paper, the structure and the working procedure of CPPIE are introduced, and Diaphragm press drying device (DPDD) in CPPIE is further described. Then, the experimental setup is arranged. Its drying and energy consumption performances are experimentally investigated. The performance of DPDD is analyzed experimentally with theory to validate it can meet the requirements of industrial applications. Furthermore, the energy consumption for the whole processes is calculated with experimental data. Compared to CPPIE without DPDD, CPPIE with DPDD has energy conservation about 25%. This work presents the feasibility of CPPIE, the advantage of DPDD for drying process with lower energy consumption, which can be referenced for designing similar integrated equipment.
