Extraction-type heat exchange system with pre-solvent trapping device

Abstract

This invention provides a removable heat exchange system with a pre-cooled solvent trapping device. The device includes multiple connecting pipes, a pre-cooled solvent trapping device, a heat exchanger, a cooling water inlet pipe, and a cooling water outlet pipe. The pre-cooled solvent trapping device utilizes a cooling water module to condense and trap the solvent in the hot air, preventing it from entering the heat exchanger module housing and causing blockage. Furthermore, both the pre-cooled solvent trapping device and the heat exchanger adopt a removable module design, allowing for quick assembly and disassembly using a sliding quick-release structure, significantly reducing maintenance downtime. This invention can effectively extend the lifespan of the main equipment and improve production uptime.

Claims

1. A heat exchange system with a pre-solvent trapping device, the system comprising: an industrial oven inner chamber; a pre-solvent trapping device including a tubular outer shell and a cooling water module disposed within the tubular outer shell, the cooling water module having a first inlet connector and a first outlet connector; a heat exchanger module housing having an air inlet end, an air outlet end, a second inlet connector and a second outlet connector, the heat exchanger module housing containing at least one heat exchanger; and a plurality of connecting pipes respectively connecting the industrial oven inner chamber, the pre-solvent trapping device and the heat exchanger module housing; wherein...
