Description

Technical Field

[0001] This utility model relates to the structure of a cyclopentane conveying pipeline, and more particularly to a cyclopentane liquid pipeline conveying and drying device. Background Technology

[0002] Currently, cyclopentane in a container is typically pumped into a high-pressure transfer pump to transfer it from the container to the equipment. This transfer is usually done via high-pressure pipelines, with an opening typically made in the container. However, during rainy seasons and periods of large temperature differences, moisture in the air easily condenses into small droplets, gradually accumulating in the container. Over time, this leads to a high moisture content in the container, far exceeding our moisture control standards. Since the containers are usually made of iron, and cyclopentane is highly flammable, moisture detection and handling are difficult. Furthermore, online real-time monitoring equipment is expensive, and only temporary sampling and testing of cyclopentane are possible, making the process cumbersome and difficult to manage.
