【Weekly Topic】Discussion on the structure of venturi scrubbers
Thread Content
As the title suggests, the venturi scrubber at the outlet of the coal pulverization pressurized gasification furnace (Lurgi furnace) is designed with a double-layer structure, and its internal design features an internal overflow venturi mechanism. Please discuss its principle as well as the issues that arise during its use It would be great to discuss the advantages and disadvantages of Venturi scrubber structures in relation to different gasification types! There are great rewards for those who participate!
The design and operation of venturi dust collectors involve a great deal of knowledge, and not many people study this field; please feel free to share your insights.
The venturi scrubber is a type of wet dust collector and belongs to the category of high-efficiency dust collectors; it is commonly used for cooling and removing dust from hot flue gases. As the gas passes through the Venturi throat, it becomes a high-speed stream that meets the water sprayed from the throat, causing the water to be atomized and to mix thoroughly with the gas. This enables the gas containing dust particles to come into close contact with the liquid, and devices that utilize the inertial collisions between water droplets and particles, as well as other mechanisms, are used to capture the dust or increase the size of the particles, thereby achieving dust separation.
Furthermore, this is a humidifier; its quality depends on the effectiveness of gas dust removal, and the mixers produced by Huali in China seem to be of good quality.
Could someone share the design specifications for the Venturi dust collector used in coal water slurry gasification?
Are there manufacturers in China capable of producing high-temperature gas Venturi scrubbers?
What is the temperature here? For wet dust removal, venturi washing should not pose too many problems regarding temperature.
The structure of the Venturi is indeed worth discussing. Generally, design institutes will develop one based on experience and the drawings from other projects.
That’s exactly right; we just want everyone to discuss the problems they have encountered while using it! Let’s see what areas can be improved.
I have made the changes on my end; the equipment is currently being manufactured, and we need to wait until it’s installed to see how it performs
I hope to understand the reasons and ideas behind your modifications; it would be great if you could share the results of their use! Thank you
