Product Features The SL type static mixer unit consists of a number of L-shaped units according to a certain rule. The technical characteristics are: liquid-liquid, liquid-solid phase mixing unevenness coefficient a√x≤1~5% The pressure drop calculation of the product is based on the hydraulic diameter and takes into account the effect of the coefficient of friction of the void ratio. SL type pressure drop calculation formula ΔP=(f*ρc/ε2W2)*L/dh Re=dh*ρc*w/μ*ε W=(Q/πD2*900)*10^6 1Kg(f)/cm2=98100N/m2 Dh=(πD2L-4Aδ)/(2A+πDL) △P resistance drop (N/m2) f friction coefficient (no dimension) ρc fluid density (Kg/m3) W fluid line speed (m/s) L mixer length (mm) dh hydraulic diameter (mm) ε void ratio (without dimension) μ fluid viscosity (CP) A total area of mixing unit (mm2) δ unit material thickness (mm) D pipe inner diameter (mm) Re Reynolds number (without dimension) Relationship between SL type Reynolds number Reε and friction coefficient f Sl type pressure drop calculation example Assume: fluid flow Q = 144.35m3 / h fluid density ρc = 897.6Kg / m3 viscosity μ=28.3CP pipe inner diameter D=250mm length L=2500mm hydraulic diameter dh=15mm void ratio ε=1 W=Q/900πD2=144.35/900*3.14*0.252=0.817m/s Re=dh*ρc*w/(μ*ε)=15*897.6*0.817/28.3*1=388.7 Check the table to get Re>150,f=1 P=(f*ρc/ε2W2)*L/dh=(1*897.6/2)*0.8172*2500*15=49928N/m2=0.5kg(f)/cm2 SL type product use Applicable to chemical, petroleum, oil and other industries, viscosity ≤ 106 centipoise or mixed with high polymer medium, heat exchangers for heat transfer, mixing and heat transfer reactions, heating or cooling of viscous products and other unit operations. SL type application example The treatment of alkali-containing sewage in refineries is troublesome. A refinery applied SL static mixer on the alkaline sewage treatment plant. Due to its high oxygenation efficiency, vertical lifting and mixing effect, the upper and lower layers of the aeration tank are dissolved. The problem of unevenness and mud accumulation at the bottom meets the process requirements. SL type product specification model table Description: 1.
