Analysis of mixing effect and power consumption of cone-bottom dual Rushton turbines stirred tank
Abstract At present, the research on stirred tanks in the chemical process has focused on the flat-bottom and dish-bottom stirred tanks, and there are few reports on the cone-bottom stirred tanks. Based on the flow pattern of the flow field in the tank, this paper analyzes the stirring effect and po...

| 520 | |a Abstract At present, the research on stirred tanks in the chemical process has focused on the flat-bottom and dish-bottom stirred tanks, and there are few reports on the cone-bottom stirred tanks. Based on the flow pattern of the flow field in the tank, this paper analyzes the stirring effect and power consumption of the cone-bottom stirred tank with dual Rushton turbines. Computational fluid dynamics (CFD) software is used to simulate the flow field characteristics in the stirred tank. The effects of the cone-bottom height, the impeller spacing and the ratio of impeller diameter to tank diameter on the power consumption and the flow pattern of the flow field in the tank are analyzed. The results show that when the ratio of cone-bottom height to the inner diameter of the tank is less than 0.0147, there is dispersed flow in the stirred tank. The dispersed flow can improve the velocity distribution of the bottom fluid. Compared with parallel flow, the power consumption and effective mixing zone of dispersed flow are reduced by 1.5% and 2.6%. When the ratio of the impeller spacing to the inner diameter of the tank is less than 0.294, the mixed flow is in the stirred tank. The fluid turbulence between the connected flow blades is the strongest, and the power consumption is relatively small. The change of the ratio of impeller diameter to tank diameter has the greatest impact on the connected flow, and the parallel flow is the least. When the ratio of impeller diameter to tank diameter is 1:1.7, the power number is reduced by 22.8% and 44.6% compared to 1:2 and 1:2.3, respectively. | ||

Based on the flow pattern of the flow field in the tank, this paper analyzes the stirring effect and power consumption of the cone-bottom stirred tank with dual Rushton turbines. Computational fluid dynamics (CFD) software is used to simulate the flow field characteristics in the stirred tank. The effects of the cone-bottom height, the impeller spacing and the ratio of impeller diameter to tank diameter on the power consumption and the flow pattern of the flow field in the tank are analyzed. The results show that when the ratio of cone-bottom height to the inner diameter of the tank is less than 0.0147, there is dispersed flow in the stirred tank. The dispersed flow can improve the velocity distribution of the bottom fluid. Compared with parallel flow, the power consumption and effective mixing zone of dispersed flow are reduced by 1.5% and 2.6%. When the ratio of the impeller spacing to the inner diameter of the tank is less than 0.294, the mixed flow is in the stirred tank. The fluid turbulence between the connected flow blades is the strongest, and the power consumption is relatively small. The change of the ratio of impeller diameter to tank diameter has the greatest impact on the connected flow, and the parallel flow is the least. When the ratio of impeller diameter to tank diameter is 1:1.7, the power number is reduced by 22.8% and 44.6% compared to 1:2 and 1:2.3, respectively.

Based on the flow pattern of the flow field in the tank, this paper analyzes the stirring effect and power consumption of the cone-bottom stirred tank with dual Rushton turbines. Computational fluid dynamics (CFD) software is used to simulate the flow field characteristics in the stirred tank. The effects of the cone-bottom height, the impeller spacing and the ratio of impeller diameter to tank diameter on the power consumption and the flow pattern of the flow field in the tank are analyzed. The results show that when the ratio of cone-bottom height to the inner diameter of the tank is less than 0.0147, there is dispersed flow in the stirred tank. The dispersed flow can improve the velocity distribution of the bottom fluid. Compared with parallel flow, the power consumption and effective mixing zone of dispersed flow are reduced by 1.5% and 2.6%. When the ratio of the impeller spacing to the inner diameter of the tank is less than 0.294, the mixed flow is in the stirred tank. The fluid turbulence between the connected flow blades is the strongest, and the power consumption is relatively small. The change of the ratio of impeller diameter to tank diameter has the greatest impact on the connected flow, and the parallel flow is the least. When the ratio of impeller diameter to tank diameter is 1:1.7, the power number is reduced by 22.8% and 44.6% compared to 1:2 and 1:2.3, respectively.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Stirred tank</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Power consumption</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Computational fluid dynamics (CFD)</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Flow pattern</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Taper</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wang, Zhao-Hui</subfield><subfield code="0">(orcid)0000-0001-9492-3057</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Fan, Yi-Wei</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Cheng, Zi-Qiang</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Chemical papers</subfield><subfield code="d">Wien : Springer Vienna, 1947</subfield><subfield code="g">76(2022), 4 vom: 29.

Analysis of mixing effect and power consumption of cone-bottom dual Rushton turbines stirred tank |
| abstract |
Abstract At present, the research on stirred tanks in the chemical process has focused on the flat-bottom and dish-bottom stirred tanks, and there are few reports on the cone-bottom stirred tanks. Based on the flow pattern of the flow field in the tank, this paper analyzes the stirring effect and power consumption of the cone-bottom stirred tank with dual Rushton turbines. Computational fluid dynamics (CFD) software is used to simulate the flow field characteristics in the stirred tank. The effects of the cone-bottom height, the impeller spacing and the ratio of impeller diameter to tank diameter on the power consumption and the flow pattern of the flow field in the tank are analyzed. The results show that when the ratio of cone-bottom height to the inner diameter of the tank is less than 0.0147, there is dispersed flow in the stirred tank. The dispersed flow can improve the velocity distribution of the bottom fluid. Compared with parallel flow, the power consumption and effective mixing zone of dispersed flow are reduced by 1.5% and 2.6%. When the ratio of the impeller spacing to the inner diameter of the tank is less than 0.294, the mixed flow is in the stirred tank. The fluid turbulence between the connected flow blades is the strongest, and the power consumption is relatively small. The change of the ratio of impeller diameter to tank diameter has the greatest impact on the connected flow, and the parallel flow is the least. When the ratio of impeller diameter to tank diameter is 1:1.7, the power number is reduced by 22.8% and 44.6% compared to 1:2 and 1:2.3, respectively. © Institute of Chemistry, Slovak Academy of Sciences 2021 |
