Definitions

  • the present invention belongs to fluid mixing equipment, and particularly relates to a pipe-type mixer having a heat-exchange function.
  • Mixing is a unit operation using a mechanical or hydrodynamic method to disperse two or more materials to each other to achieve a certain degree of uniformity.
  • mechanical stirring, gas circulation stirring and hydraulic stirring are used to achieve a mixing purpose.
  • many projects or project mating processes require heating or temperature control in feedstock, discharging and reaction. Temperature affects the system energy consumption and is a key factor of ensuring normal and efficient reaction processes. Therefore, combining a heat-exchange technology with a mixing technology to research and develop an efficient and energy-saving mixer is of great significance for reducing the production costs and saving the energy.
  • mixing equipment commonly used in the industry comprises a stirring and mixing kettle, a static mixer and a circulation mixer.
  • Commonly used heat-exchange equipment comprises a pipe-type heat exchanger, a plate heat exchanger and a finned heat exchanger.
  • these equipment may not simultaneously enhance mixing and heat exchange, which limits the selection of process solutions and conditions and has become a major bottleneck in enhanced transfer of a fluid process.
  • process raw materials such as a fermentation raw material (straws and poultry manure systems etc.), have high solid content, high apparent viscosity and complex rheological property. These factors may all cause blockage and fouling of the equipment, so that the transfer efficiency of the process is substantially reduced, and the continuous and stable operation of a system is affected.
  • mixers are inserted into many heat exchangers, such as a horizontal liquid-solid fluidized bed heat exchanger with a Kenics static mixer inserted in a pipe.
  • This configuration may effectively improve the particle distribution.
  • the heat exchangers of this type of structures are only suitable for systems with low solid content of 2 wt% to 4 wt%. This is because the presence of a part-in-pipe makes systems with high solid content have extremely high flow resistance during heat exchange and thus the power consumption in this process is increased.
  • pipe-type mixers have developed rapidly, such as a multi-pole vortex pipe-type mixer, an S-K type mixer and a pipe bundle pipe-type static mixer, which are mainly suitable for filtering flocculates in water.
  • This type of pipe-type mixer is only suitable for simple fluids with low solid content and low viscosity, such as sewage.
  • Chinese patent CN201510185307.8 invents a pipe-type mixer with a spiral passage. A spiral groove is formed in the outer wall of an inner pipe, and the spiral groove is connected with the inner wall of an outer pipe to form the spiral passage.
  • the mixer of this structure may provide a large mixing length in a short axial distance and provide a better mixing effect within the same mixing time.
  • this configuration is only suitable for the systems with low solid content.
  • this passage is easily blocked, and thus the mixing effect may be reduced.
  • the patent is only for enhanced mixing, but not for enhanced heat exchange at the same time.
  • Chinese patent CN201510305639.5 invents a sleeve pipe-type heat exchanger suitable for sewage with high solid content.
  • This sleeve pipe-type heat exchanger is suitable for the sewage with high solid content, and dirt impurities in the sewage are not easily fouled on four walls of a sewage passage or do not easily block the sewage passage, thereby guaranteeing the heat-exchange efficiency and the continuous and stable operation of the heat exchanger.
  • the heat exchanger has relatively high enhanced heat-exchange performance.
  • the cross section of a twisted pipe in the heat exchanger is a triangle.
  • a twisted pipe heat exchanger a twisted pipe of which has an elliptical cross section, has certain advantages in the enhanced heat-exchange performance, the twisted pipe heat exchanger is limited to single-phase fluids without solid particles, such as sulfuric acid cooling, ammonia preheating and lubricating oil cooling.
  • the present invention is directed to provide a pipe-type mixer which aims at a complex fluid with high solid content and high viscosity or containing fibers and also realizes enhanced mass transfer and heat transfer, and has anti-fouling, anti-blockage and alternative mechanical stirring functions.
  • the present invention has important application background in fields of petrochemical engineering, food processing and biofermentation etc.
  • a pipe-type mixer comprising an inner sleeve pipe taking a mixing action and an outer sleeve pipe taking a heat-exchange action.
  • the inner sleeve pipe is located inside the outer sleeve pipe, and the cross section of the inner sleeve pipe is a hexagon, and the cross section of the inner sleeve pipe is a hexagon and is formed of a combination of an inner pipe twisting clockwise along the pipe centre and an inner pipe twisting anticlockwise.
  • the pipe-type mixer is suitable for a material system with high solid content and high viscosity, and has the advantages of simple structure, anti-blockage and anti-fouling performance and integration of heat exchange and mixing.
  • the cross section of the inner sleeve pipe is an equilateral hexagon.
  • the centre axis of the inner sleeve pipe is straight or curved. Preferably, a straight centre axis is used.
  • the inner sleeve pipe is formed of a combination of an inner pipe uniformly twisting clockwise along the pipe centre and an inner pipe uniformly twisting anticlockwise.
  • a torque of the inner sleeve pipe namely a pipe length corresponding to a pipe wall spirally deforming 360 degrees around the pipe centre axis, is 300 to 800 mm, preferably 500 to 800 mm.
  • an extremely high torque causes a too small space of a medium passage, and then the mixer may not work normally and is easy to foul, but an extremely low torque may reduce the mixing and heat-exchange effect.
  • the torques of the two sections of inner pipes twisting clockwise and anticlockwise may be the same or different, which has no obvious impact on the mixing and heat-exchange effect.
  • the inscribed circle diameter of the hexagonal cross section of the inner sleeve pipe is 20 to 150 mm, preferably 80 to 150 mm.
  • both a too large inscribed circle diameter and a too small inscribed circle diameter may affect the heat-exchange efficiency and the mixing effect and easily cause wall surface fouling or blockage of the inner sleeve pipe.
  • the shape of the cross section of the outer sleeve pipe which may be a circle, a square, a hexagon and the like.
  • the cross section of the outer sleeve pipe is preferably a circle.
  • a distance between the inscribed circle diameter of the inner sleeve pipe and the inscribed circle diameter of the outer sleeve pipe is 5 to 15 mm, preferably 10 to 15 mm. Experiment finds that both a too large distance and a too small distance may reduce the heat-exchange effect. Particularly, the too large distance also may cause higher energy consumption and cost.
  • the inscribed circle diameters of the inner sleeve pipe and the outer sleeve pipe may be adjusted within the scope of the present invention according to an actual requirement.
  • an inner sleeve pipe with the inscribed circle diameter D 1 of 20 to 80 mm and an outer sleeve pipe with the inscribed circle diameter D 2 of 30 to 95 mm are preferably used, and for a material with total solid content TS of 10% to 15%, an inner sleeve pipe with the inscribed circle diameter D 1 of 80 to 150 mm and an outer sleeve pipe with the inscribed circle diameter D 2 of 95 to 165 mm are preferably used.
  • a combination of one section of inner pipe twisting clockwise along the pipe centre and one section of inner pipe twisting anticlockwise is used as a constituting unit.
  • the sleeve pipe of the present invention may comprise one or more such constituting units.
  • the length ratio within this range has no obvious impact on the mixing effect, and the length ratio less than or greater than this range may cause an obvious reduction of the mixing effect.
  • the pipe-type mixer of the present invention comprises a material mixing passage and a heat-exchange medium passage.
  • the material mixing passage is composed of the inner sleeve pipe. Two ends of the material mixing passage are respectively provided with a material inlet and a material outlet.
  • the heat-exchange medium passage is composed of an annular space between the outer sleeve pipe and the inner sleeve pipe. Two ends of the heat-exchange medium passage formed by the space between the outer sleeve pipe and the inner sleeve pipe may be closed.
  • a heat-exchange medium inlet pipe and a heat-exchange medium outlet pipe are arranged on the heat-exchange medium passage or a heat-exchange medium main passage.
  • the material inlet corresponds to the heat-exchange medium outlet pipe
  • the material outlet corresponds to the heat-exchange medium inlet pipe.

  • 4 B inlet pipe

  • 8 cross section of hexagonal inscribed circle O 1

  • 10 cross section of outer sleeve circular pipe O 2 .
  • a pipe-type mixer which aims at complex fluids with high solid content and high viscosity or containing fibers and also realizes enhanced mass transfer and heat transfer comprises an inner sleeve pipe and an outer sleeve pipe.
  • the inner sleeve pipe is located inside the outer sleeve pipe, and the cross section of the inner sleeve pipe is a hexagon and is formed of a combination of an inner pipe twisting clockwise along the pipe centre and an inner pipe twisting anticlockwise.
  • the pipe-type mixer is suitable for a material system with high solid content and high viscosity, and has the advantages of simple structure, anti-blockage and anti-fouling performance and integration of heat exchange and mixing.
  • the inner sleeve pipe of the present invention may be a hexagonal twisted pipe which has a hexagonal cross section formed of a combination of an inner pipe uniformly twisting clockwise along the pipe centre and an inner pipe uniformly twisting anticlockwise.
  • the cross section of the hexagonal twisted pipe is a regular hexagon, and the centre axis thereof is straight or curved.
  • the straight centre axis as shown in Fig. 2 is used.
  • Torque is one of important parameters of the hexagonal twisted pipe, namely a pipe length corresponding to a pipe wall spirally deforming 360 degrees around the pipe centre axis.
  • the torque of the hexagonal twisted pipe is 300 to 800 mm.
  • the inscribed circle diameter of the hexagonal cross section of the hexagonal twisted pipe is 20 to 150 mm, as shown in Fig. 3 .
  • the outer sleeve pipe in the example may be a common circular sleeve pipe.
  • the cross section of the outer sleeve pipe is a circle, and the pipe diameter is greater than that of the inner sleeve pipe.
  • a distance between the wall of the outer sleeve pipe and the inner sleeve pipe is 5 to 15 mm.
  • the cross sectional structures of the inner and outer sleeve pipes are as shown in Fig. 3 .
  • Fig. 1 illustrates a relatively complete pipe-type mixer, consisting of an outer sleeve pipe 1, an inner sleeve pipe 2, a material A inlet 3, a material B inlet 4, a material outlet 5, a heat-exchange medium inlet 6 and a heat-exchange medium outlet 7.
  • the outer sleeve pipe is a heat-exchange medium passage
  • the inner sleeve pipe is a material mixing passage.
  • the inner sleeve pipe is located inside the outer sleeve pipe.
  • the cross section of the inner sleeve pipe is a hexagon and is formed of a combination of one section of inner pipe uniformly twisting clockwise along the pipe centre and one section of inner pipe uniformly twisting anticlockwise, as shown in Figs.
  • the outer sleeve pipe is provided with a heat preservation material.
  • the outer sleeve pipe was a circular sleeve pipe; a material A was a straw; a material B was a CMC (Carboxy Methylated Cellulose) solution (with a mass fraction of 1%); and a heat-exchange medium was water.
  • the temperature of the material inlet was 10°C, and the temperature of the heat-exchange medium inlet was 55°C.
  • the mixing effect was characterized by a tracer agent method.
  • a KCl solution at a concentration of 0.7 mol/L was injected at the inlet, and a voltage thereof was measured with a conductivity meter (DDSJ-308A) at the outlet.
  • ⁇ ⁇ 2 and a Berkeley number (Pe) of residence time distribution were calculated by the voltage. If ⁇ ⁇ 2 is closer to 1, the mixing effect is better; and if Pe is closer to 0, the axial back-mixing is grater, and the flow state is close to complete mixing flow.
  • the materail inlet speeds are the same, and the heat-exchange medium inlet speeds are also the same; D 1 is the diameter of a hexagonal inscribed circle, and D 2 is the diameter of an outer pipe; n 1 and n 2 are resectively torques of the two sections of twisted pipes; and L 1 and L 2 are respectively lengths of the two sections of twisted pipes (as shown in Fig. 2 ).
  • the mixer of Comparison Example 1 has relatively high hext-exchange performance, but the fluid stirring of the hexagonal structure twisting towards the same direction is not as good as that of the mixer of Embodiment 1.
  • the triangular twisted pipe mixer of Comparison Example 3 has relatively good heat-exchange effect, the mixing effect is not as good as that of the hexagonal twisted pipe.
  • the hexagonal straight pipe and the elliptical twisted pipe are blocked and thus may not be meaasured.
  • the pipe-type mixer with the twisted pipe having the hexagonal cross section has relatively good effect.
  • Embodiments 1 to 3 since the extremely high torque of the hexagonal twisted pipe of the material passage makes the space of the medium passage too small and then causes the mixer to be unable to work normally, the twisted pipe with the torque exceeding 800 mm is easily fouled, and an extremely low torque may reduce the mixing and heat-exchange effect. Therefore, the mixing and heat-exchange effects of the mixers of Embodiments 2 to 3 are not as good as that of the mixer of Embodiment 1. If the torque of the twisted pipe is within 300 to 800 mm, the mixing and heat-exchange effect is relatively good. If the torque exceeds this range, the twisted pipe is easily fouled or blocked, and the mass transfer and heat transfer effect is reduced.
  • prevention of blockage and fouling and enhanced mixing and heat exchange may be realized by changing the torques, lengths or hexagonal inscribed circle diameters of the two sections of twisted pipes and the diameter of the outer pipe.
  • the torques and the lengths of the two sections of twisted pipes are respectively changed, while in Embodiment 7, the structural sizes of the inner pipe and the outer pipe are changed. It can be seen according to characterization results that the mixing and heat-exchange effect is close to that of Embodiment 1, so that the above various combinations may be flexibly selected according to specific situations in actual operation.
  • Embodiment 6 and Comparison Example 5 it can be seen from Embodiment 6 and Comparison Example 5 that for materials with high solid content and high viscosity and containing fibers, a too small hexagonal inscribed circle diameter easily causes blockage. It can be seen from Embodiment 1 and Comparison Examples 6 to 7 that under the condition of the same inner pipe, decrease or increase of the annular space between the inner pipe and the outer pipe has little impact on the mixing effect, but a too small annular space may lead to an insufficient temperature difference which is not enough to heat the material in the inner pipe, so the heat-exchange effect is reduced; and on the contrary, if the annular space is too large, the cooled heat-exchange medium may not flow out in time, which will also lead to an insufficient temperature difference, so the heat-exchange effect is also reduced, and meanwhile, higher energy consumption and cost also may be caused.
  • Embodiment 7 and Comparison Example 8 that a too large hexagonal inscribed circle diameter may cause slight fouling, which damages a rotational flow pattern and increases heat-exchange heat resistance, thereby reducing the mixing effect and the heat-exchange performance.
  • an inner pipe with D 1 of 20 to 80 mm and an outer pipe with D 2 of 30 to 95 mm are preferably used, and for a material with the TS of 10% to 15%, an inner pipe with D 1 of 80 to 150 mm and an outer pipe with D 2 of 95 to 165 mm are preferably used.
  • strong anti-fouling and anti-blockage functions and relatively high mixing effect and heat-exchange performance may be achieved, while the foregoing effects may be severely affected in case of relatively large deviations.
  • the pipe-type mixer having a heat-exchange function may be transformed into various specific structural forms according to the structural features. For example, a plurality of inner sleeve pipes are arranged in the outer sleeve pipe; the torques and the pipe diameters are changed according to different material systems, and a plurality of inner pipes uniformly twisting clockwise and inner pipes uniformly twisting anticlockwise are arranged and combined.
  • the inner sleeve pipe of the present invention also may comprise one or more constituting units.
