Description
Technical field
The utility model relates to the logistics of a kind of petroleum and petrochemical industry gas-liquid two-phase and uses blender.
Background technology
There is gas-liquid delivery in the petrochemical industry section of tubing,, need makes the gas-liquid uniform inflow as far as possible mixing defeated pump intake place installation air and liquid mixer in order to guarantee the normal operation in mixed transporting tube road; Have the processes such as reaction, absorption, extraction, dissolving and emulsification between gas-liquid two-phase in the part unit, these technical process all need to realize through the mixed process between gas-liquid two-phase, in order to improve mixing efficiency, in the flow process air and liquid mixer must be set.
In the gas-liquid two-phase mixed process, the complexity that gas is carried under one's arms by liquid is relevant with the thickness degree with the flow surface, and the flow surface is big more, and thickness is thin more, and gas more is prone to infiltrate in the flow of turbulent flow.The efficient of air and liquid mixer just depends on two parts: gas-liquid contact process and gas-liquid mixed process.The gas-liquid contact portion the most simply is the contact of concentric tube single-point, and the multiple spot contact of special construction is also arranged; The unit elements that gas-liquid mixed partly adopts has multiple; Comprise V-type mixed cell, X type mixed cell, L type mixed cell, H type mixed cell and K type mixed cell that JB/T 7660-1995 introduces; Every kind of mixed cell structure is different, and applicable situation also is not quite similar.
When adopting the contact of concentric tube single-point, gas forms a Gas Jet awl in flow, and when large-minded, annular flow will cause the blender integral pressure to increase rapidly, and air-flow will flow the air-teturning mixed phenomenon of generation systems when further worsening along fluid pipe is counter.The contact of concentric tube single-point also can be along air injection pipe generation wall suction phenomenon in fluctuation of operating conditions, and liquid speed increases rapidly, and fluctuation of operating conditions is huge, the gas-liquid mixed severe exacerbation, and 94242341.0 have introduced a kind of air and liquid mixer of single-point contact; The multiple spot contact is used more at present in industry, and different occasions version is not quite in full accord, and the gas-liquid contact portion of 02201093.9 introduction belongs to the multiple spot contact.
02201093.9 adopted contact of gas-liquid multiple spot and left and right sides vane sheet to mix, effect is obvious in gas dissolving liquid field, is fit to large-scale production; But hour in the fluid pipe size; Air inlet pipe the multiple spot layout will be difficult to abundant realization, whole mixed process all is to adopt eddy flow to mix, exist in liquid phase impurity situation certain advantage arranged; But lack the bubble breaking structure, mixing efficiency is relatively low.
The utility model content
