Has anyone ever seen this kind of separator?
Thread Content
The separator in our company’s conversion unit features top-entry and side-output design; the incoming air is separated through the guide vanes as shown in the diagram, with the liquid flowing down along the wall surface while the gas enters an upward-opening pipe to exit the separator. Recently, tube blockages occurred in the downstream medium-temperature heat exchangers, forcing a shutdown for cleaning. It is suspected that the separation effect is poor. Has anyone seen a separator of this type before? Are there any relevant materials available? Thank you first!
I’m not entirely sure about the specific process, so out of curiosity I’m asking: is it possible to add a filter or something before this separator, so that these deposits can be collected and removed regularly?
Thank you! Filters can be added, but installing a set of pipeline filters for DN600 high-pressure pipes is quite expensive, and they tend to get clogged easily.
The hat-like structure in the image is likely an axial flow guide vane, intended to rotate the airflow and use centrifugal force to separate water from air. But I have never seen any information on separators of this kind. Which sea friend can help take a look? Thank you!
Water-coal slurry? Briquette coal? Fixed bed? I’ve really never seen anything like this. Which department designed it?
This filter serves as a coarse filter, capable of separating gas from liquid or gas from solid. As the gas rises, it encounters deflecting structures; dust or liquid droplets are struck and intercepted, and their velocity decreases as they fall due to gravity
Pressurized coal gasification into a shift separation unit, designed by the internal components manufacturer
Gas enters from the top of the umbrella. Due to poor separation, water and ash are carried along, causing blockages in the downstream heat exchangers.
May I ask which company designed the internal components? Normally, a separator as efficient as yours shouldn’t experience blockages; feel free to contact me if you need any help
The separator of the structure shown by the poster is a dynamic umbrella-type separator, which falls under the category of dynamic separators and is specified for use in SD process packages abroad. Dynamic umbrella separators must be developed by specialized companies in dynamic separation technology that possess accurate systems for dynamic separation calculations and configuration design. The process parameters and physicochemical data of the light and heavy phase systems need to be fully input into such systems in order to obtain a complete technical solution for the separator. The internal structural parameters of dynamic umbrella separators, their installation positions, shell dimensions, pipe port locations, etc., must all be determined through accurate dynamic separation calculations and a configuration design system platform; they cannot be decided arbitrarily based on guesswork, as is the case with many suppliers in China. Otherwise, the separation efficiency drops rapidly or there is no separation effect at all.
