How is powdered calcium oxide transported?
Thread Content
Calcium oxide powder is continuously fed into a sealed reaction vessel, where the pressure inside is around 3 kilograms of positive pressure. How can it be transported using a pump? Is there such a pump? . Also, there is water in the reaction tank; when calcium oxide comes into contact with water, it sticks to the feed inlet. What should be done? Contact email: dy6680@163.com
Such pumps are hard to find; let’s see if we can solve the problem from a technical perspective.
This is quite simple; there are two options: one is to use lime milk made from calcium oxide, and the other is to feed in the powder directly. I’m not sure what particle size requirements you have What is the feed rate?
Personally, I think the screw conveyor method could be considered.
Calcium oxide is quicklime; it has poor fluidity, so batch feeding could be considered. I have relevant information available for reference at 13585777886
I think the same. Pneumatic conveying reactors may not be suitable.
Even pneumatic screws don’t work; there’s a pressure of 3 kilograms inside. It’s still possible to get it there by using a pump to inject the lime slurry.
This is a more reliable approach; using a screw conveyor under pressure definitely won’t work. Since there is liquid inside the reactor, it’s sufficient to draw out some of the reactor solution, turn calcium oxide into a slurry, and then pump it in using a fluid pump.
