How to clean a clogged feed pipe in a falling-film evaporator?
Thread Content
Recently, the film evaporator in the factory became clogged due to tar. How should it be cleaned?
Check whether the material is tar or salt; if it is tar, heat it to soften it and then add a solvent for cleaning.
When designing, one should consider how to overcome the blocking issues. The process engineering and equipment engineering fields should have something to say on this.
