SK static mixer

詳細(xì)介紹

SK type static mixer product features The SK type static mixer is called a single spiral static mixer. The unit of the SK type static mixer is a spiral plate that is twisted by 180° or 270°. When installed in the shell, the adjacent spiral plates are left-handed and right-handed. Compared with the SV static mixer, the SK static mixer has a poor mixing effect and obvious amplification effect, but the SK static mixer is not easy to block and is suitable for materials with more impurities. The SK type static mixer can be used to disperse droplets to 10μm during the emulsification process. It is used in the general mixing process. The unevenness coefficient is a√x≤1~5%. The pressure drop of the product is calculated as the static mixer equivalent diameter and inner diameter. D is expressed by the friction coefficient ΨD of the reference. SK type static mixer calculation formula △P=(f*ρc/2)*W2*L/D Re=dh*ρc*w/μ W= Q/πD2*900 1Kg(f)/cm2=98100N/m2 △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) Table of relationship between SK Reynolds number Reε and friction coefficient f SK type static mixer pressure drop calculation example Assumption: Fluid flow rate Q=140m3/h Fluid density ρc=800Kg/m3 Viscosity μ=28CP Pipe inner diameter D=200mm Length L=2000mm Hydraulic diameter dh=100m W=Q/900πD2=140/900*3.14*0.22=1.24m/s Re=dh*ρc*w/μ=100*800*1.24/28=3538 Check the table to get Re>150, f=1 △P=(f*ρc/2)*L/D=(2.53*800*1.242/2)*2000/200=15560.5N/m2=0.16Kg(f)/cm2 SK type static mixer product use SK type static mixer is suitable for mixing, reaction, extraction, absorption, injection molding, color matching, heat transfer and other processes in chemical, petroleum, pharmaceutical, food, fine chemicals, plastics, environmental protection, synthetic fiber, mining and metallurgy departments. Highly viscous media with medium or small flow and impurities or viscosity ≤ 106 centipoise are especially suitable. SK static mixer application example Application of SK static mixer in asphalt removal equipment with propane as solvent: a propane deasphalting device of a plant uses vacuum residue as raw material, liquid propane as solvent, liquid-liquid extraction to produce high viscosity The lubricating oil is used to catalytically crack the raw material, and at the same time, the asphalt is obtained, which achieves good residue dilution, improves the oil recovery rate, reduces the solvent ratio, and saves energy consumption. Application of SK static mixer in pulp chlorination process: A paper mill uses SK static mixer, the chlorine content meets the process requirements, guarantees the quality of the bleaching pulp, and the chlorine gas is fully dispersed in the slurry, and the reaction absorption is completely The production is normal, there is no overflow of chlorine, the production environment is improved, and the quality of the slurry is improved.
