For double-alkali desulfurization towers, what kind of nozzles are suitable?
Thread Content
Hello everyone, may I ask what kind of nozzles are suitable for double-alkali flue gas desulfurization towers? Generally, spiral nozzles are used, right? Is it better to use PP or ceramic for the material?
No one is answering at all 0 0.
Which double-alkali method? Why use a spiral nozzle? Can’t a solid conical one be used? !
It involves using NaOH as a desulfurization agent, with quicklime being used in the regeneration tank. I just think that the spiral nozzles seem to provide a better coverage and misting effect~ Do you have any suggestions, sir? It is used to desulfurize and remove dust from the flue gases generated by firing in brick factories
In our lime-gypsum process, silicon carbide nozzles are generally used. If you use NaOH, you need to pay attention to whether there are any particles in your slurry, as regeneration is carried out using calcium hydroxide, and quicklime usually contains impurities that can end up in the slurry. PP nozzles may not be able to withstand such conditions for long. . .
The lifespan of PP should be relatively short, right? Its temperature resistance isn’t high either!
It seems that silicon carbide will be used. For a spray tower with a diameter of 2.5 meters, how should one calculate the number of nozzles required? I’m using a spiral nozzle with a 1/2 inch diameter
You need to ask the supplier for the flow rate per nozzle, and then divide the total flow rate by that value. The tower has a diameter of 2.5 meters; what is the material of the tower? Is it carbon steel?
