Description

Technical Field

[0001] The utility model relates to the technical field of fractionation towers for steam bubbles to pass through liquids, in particular to a high-purity pentane foaming agent fractionation separation plate floating valve tower. Background Art

[0002] Foaming agent is a substance that makes the target substance form pores. It can be divided into three categories: chemical foaming agent, physical foaming agent and surfactant. Pentane foaming agent will use the floating valve tower for distillation separation to achieve the purpose of improving the purity of pentane foaming agent. The floating valve tower is a new tower type developed, which is characterized by installing a valve plate that can move up and down at each sieve hole.

[0003] Among them, the tower plate is the main component of the floating valve tower. Most of the floating valve tower plates are designed as an integral structure.
