SV static mixer

詳細(xì)介紹

SV static mixer product features The SV internal unit is assembled from well-designed corrugated sheets. The product itself has no moving parts. The special structure and fluid motion of the unit make the mutually incompatible fluids disperse and mix with each other to achieve a good mixing effect. The SV type unit is a cylinder assembled from a corrugated board of a certain specification. Technical characteristics: the highest dispersion degree is 1-2 μm, and the liquid-liquid phase unevenness is a√x ≤ 1 to 5%. The pressure drop calculation of the product is based on the hydraulic diameter and takes into account the effects of void ratio and friction coefficient. SV 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 SV Reynolds Number Re and Friction Coefficient f SV 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 ΔP=(f*ρc/ε2W2)*L/dh=(1*897.6/2)*0.8172*2500*15=49928N/m2=0.5kg(f)/cm2 SV type static mixer product use It is suitable for the mixing, emulsification, reaction, absorption, extraction, strengthening and heat transfer of liquid-liquid, liquid-gas and gas-gas with viscosity ≤102 centipoise. SV static mixer application example The SV type static mixer is used for oil blending. A refinery cracking workshop uses the SV static mixer of our factory for oil blending, and has achieved good results, which is superior to the orifice mixing column in terms of product quality and energy consumption. The SV type static mixer is used for gas blending. A gas plant uses the SV static mixer to achieve the desired goal, basically meets the requirements of gas interchangeability, can meet the needs of low-low pressure mixing process, and demonstrates the simplicity, stability and economic superiority of the process. . SV static mixer selection table Description: 1. The nominal pressure is determined according to the user's process conditions. 2, material: stainless steel, carbon steel, titanium, PTFE, polypropylene, etc. 3, flange standard: match the user connection piece, can provide matching flange 4, the mixing unit can be designed to be made into a drawable or fixed type 5, hourly flow is based on water
