[0054] Example 1
[0055] 1. Use environment and parameters
[0056] This application example is a jet microbubble aerator for sewage treatment, in which the volume flow rate of sewage is 13m 3 / h, according to the relevant requirements of sewage treatment, the gas-liquid volume flow ratio is 0.1.
[0057] 2. Program introduction
[0058] Combine Figure 5 with Image 6 , The jet microbubble aeration device designed according to the prior art, the design parameters closely related to the present invention are: the diameter of the inlet pipe Where Q l Is the liquid flow, u l1 Design flow rate for liquid; nozzle diameter Where φ is the nozzle velocity coefficient, P l Is the liquid flow rate, ρ is the fluid density; the length of the nozzle of the inlet pipe shrinks L n =a n (d l -d n ), where a n Is the nozzle contraction length coefficient; intake pipe diameter Where q is the gas-liquid flow ratio, u g2 Design flow rate for gas; suction chamber diameter d s =a ds d l , Where a ds Is...
