Solve for ejector calculation and selection! !
Thread Content
First-stage ejector (gas-forcing-solid): Primary fluid: compressed air, pressure 0.3 MPa, flow rate 15 cubic meters per minute (at 0.3 MPa); Fluid to be ejected: 40-mesh powder, bulk density 0.9 T/cubic meter, flow rate 0.5 T/h, at atmospheric pressure. Second-stage ejector (gas-solid mixture-forcing-liquid): Primary fluid: gas-solid mixture output from the first-stage ejector； Fluid to be entrained: slurry, with a density of 1.2 T/cubic meter, viscosity of 200 cP, and flow rate of 2 T/h. The required outlet pressure for the secondary ejector is 0.05 MPa – is this feasible? What should be the slurry head pressure for secondary impingement? (I’m not sure if the conditions are sufficient; a beginner in this field is seeking advice from experts. Thank you.)
There’s not much interest here; a post posted here goes unread for a whole day – I have to upvote it myself
I don’t understand it either; come and learn it* haha. Could some expert help with the calculation?
