Detailed implementation manners

[0032] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0033] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "horizontal", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings. These are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention.

[0034] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0035] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] Plate heat exchangers have the advantages of high heat transfer efficiency, compact structure, convenient maintenance, etc., and are commonly used for the rapid sterilization of fluid foods.

[0037] A plate heat exchanger is composed of a pair of end plates and a tube bundle formed by stacking a plurality of plates. Cold and hot fluids flow through the odd or even layer channels in the tube bundle respectively, and heat transfer through the plates is used to achieve high-temperature sterilization, and the special-shaped sealing gaskets between the plates are used to prevent mixing and leakage.

[0038] However, the flow channel shape of the existing plate heat exchanger is simple. When dealing with high-viscosity fluids, affected by the slow flow velocity and high viscosity of the high-viscosity fluids, the flow direction of the high-viscosity fluids inside is single, the fluid motion is in a relatively stable state, dirt is easy to deposit, resulting in blockage, and for the fluid in the stable motion state, the heat transfer coefficient is reduced and the heat exchange efficiency is not high.

[0039] In the embodiments of the present invention, a tube bundle unit formed by stacking a plurality of plates in the up and down directions is arranged in the shell. Flow channels are formed between any two plates. High-viscosity cold fluid and hot fluid flow through the upper and lower sides of the plates respectively, and heat exchange is carried out through the plates. The flow directions of the high-viscosity cold fluid and the hot fluid are set in opposite directions to improve the convective heat transfer of heat. The plates are set as corrugated plate structures with a funnel shape, having ridges and grooves. On the one hand, setting the plates as a funnel shape can increase the heat exchange area and further improve the flow velocity of the fluid by using the gravity generated by the funnel shape. On the other hand, setting the plates as a corrugated structure disturbs the flow direction of the fluid, helps the fluid to be turbulent, increases the flow velocity of the fluid and the heat convection heat transfer coefficient, alleviates the phenomena of easy blockage and easy fouling of high-viscosity fluids, and thus the heat exchange efficiency is improved, further improving the sterilization effect of high-viscosity fluids.

[0040] The following combination Figures 1 to 8A funnel - type sterilization device for high - viscosity fluids provided by the present invention specifically includes a housing 1. The housing 1 is a cylindrical structure composed of a top plate, a bottom plate, and side walls. Inside the housing 1, there is a plate bundle unit 2 formed by stacking a plurality of plates 21 in the vertical direction. Flow channels are formed between the plates 21. Each plate 21 is a funnel - shaped corrugated plate structure with a ridge part and a groove part. A first fluid inlet 3 is provided at the top of the housing 1.

[0041] A fluid channel unit 4 is provided at the center of the plate bundle unit 2. The fluid channel unit 4 includes a first fluid channel A41 and a second fluid channel C42. The first fluid channel A41 and the second fluid channel C42 are separated by a partition and are not connected to each other. The first fluid inlet 3 is connected to the flow channels of the odd - numbered layers of the plate bundle unit 2 through the first fluid channel A41.

[0042] A first fluid channel B5 is provided on the side wall of the housing 1. A first fluid outlet 6 is provided on the first fluid channel B5. The first fluid outlet 6 is connected to the flow channels of the odd - numbered layers through the first fluid channel B5. A second fluid channel D7 is provided on the side wall of the housing 1. A second fluid inlet 8 is provided on the second fluid channel D7. The second fluid inlet 8 is connected to the flow channels of the even - numbered layers of the plate bundle unit 2 through the second fluid channel D7. The bottom of the second fluid channel C42 is a second fluid outlet 9. The second fluid outlet 9 is connected to the flow channels of the even - numbered layers through the second fluid channel C42.

[0043] In this embodiment, a plurality of plates 21 are stacked in the vertical direction in sequence. Flow channels are formed between any two plates 21. Cold fluid and hot fluid flow through the upper and lower sides of the plates 21 respectively, and heat exchange is carried out through the plates 21 to achieve the effect of high - temperature sterilization of high - viscosity fluids. The plates 21 are set as funnel - shaped corrugated plate structures with ridge parts and groove parts. On the one hand, setting the plates 21 as funnel - shaped can increase the heat - exchange area. On the other hand, setting the plates 21 as corrugated structures can disturb the flow direction of the fluid by using the corrugated structure, which helps to make the fluid turbulent, increases the flow velocity of the fluid and the heat - convection heat - transfer coefficient, alleviates the phenomenon that high - viscosity fluids are prone to blockage and fouling, and thus improves the heat - exchange efficiency, further improving the sterilization effect of high - viscosity fluids.

[0044] In this embodiment, the hot fluid enters from the first fluid inlet 3. Under the disturbance of the corrugated structure on the first layer of plates 21 of the plate bundle unit 2 and the influence of the gravity of the funnel-shaped flow channel, the hot fluid enters the first fluid channel A41 of the fluid channel unit 4 provided at the center of the plate bundle unit 2. The top of the second fluid channel C42 is separated by the second fluid partition 421 to prevent the hot fluid from entering. The hot fluid entering the first fluid channel A41 is dispersed into the odd-numbered flow channels. The flow direction of the hot fluid in the flow channels is from the center of the plate bundle unit 2 to the edge, and finally flows into the first fluid channel B provided on the side wall of the housing 1 to converge, and finally flows out from the first fluid outlet 6. The first fluid channel B5 is only connected to the odd-numbered flow channels, and the even-numbered flow channels are separated by partitions. Similarly, the high-viscosity cold fluid to be processed enters the second fluid channel D7 from the second fluid inlet 8. Similarly, the second fluid channel D7 is only connected to the even-numbered flow channels, and the odd-numbered flow channels are separated by partitions. The high-viscosity cold fluid in the second fluid channel D7 is dispersed into the even-numbered flow channels. The flow direction of the high-viscosity cold fluid in the flow channels is from the edge of the plate bundle unit 2 to the center, which is opposite to the flow direction of the hot fluid, improving the convective heat transfer of heat. After the high-viscosity cold fluid in the even-numbered flow channels exchanges heat with the hot fluid in the odd-numbered flow channels through the plates 21, it finally converges into the second fluid channel C42 of the fluid channel unit 4 and finally flows out from the second fluid outlet 9.

[0045] In order to solve the problems of easy blockage and poor heat exchange efficiency during the heat exchange process of high-viscosity fluids, in this embodiment, a plate bundle unit 2 formed by stacking a plurality of plates 21 in the vertical direction is provided in the housing 1. A flow channel is formed between any two plates 21. The high-viscosity cold fluid and the hot fluid flow through the upper and lower sides of the plates 21 respectively, and heat exchange is carried out through the plates. The flow directions of the high-viscosity cold fluid and the hot fluid are set to be opposite to each other to improve the convective heat transfer of heat. Through heat exchange by the plates 21, the plates 21 are set as a corrugated plate structure with a funnel shape and having ridges and grooves. On the one hand, setting the plates 21 as a funnel shape can increase the heat exchange area and further improve the flow velocity of the fluid by using the gravity generated by the funnel shape. On the other hand, setting the plates 21 as a corrugated structure can disturb the flow direction of the fluid by using the corrugated structure, which helps the fluid to be turbulent, increases the flow velocity of the fluid and the convective heat transfer coefficient, reduces the phenomena of easy blockage and easy fouling of high-viscosity fluids, and thus improves the heat exchange efficiency, and further improves the sterilization effect of high-viscosity fluids.

[0046] Such as Figure 3As shown, in some embodiments of the present invention, the fluid channel unit 4 is of a cylindrical structure. Both the first fluid channel A41 and the second fluid channel C42 are provided in two numbers. Each of the first fluid channel A41 and the second fluid channel C42 is a sector structure of a quarter circle arc. The first fluid channels A41 and the second fluid channels C42 are distributed pairwise opposite to each other, and the first fluid channels A41 and the second fluid channels C42 are not connected to each other. And a second fluid partition 421 is provided at the top of the second fluid channel C42 for separation, so that the hot fluid entering from the first fluid inlet 3 enters and circulates through the two relatively distributed first fluid channels A41 respectively, improving the feeding speed of the hot fluid. Similarly, the highly viscous cold fluid in the flow channel enters through the two relatively distributed second fluid channels C42 respectively and flows out from the second fluid outlet 9, improving the feeding speed of the highly viscous cold fluid.

[0047] As Figure 1 and Figure 4 shown, in some embodiments of the present invention, both the first fluid channel B5 and the second fluid channel D7 are provided in two numbers. Each of the first fluid channel B5 and each of the second fluid channel D7 is a gradually expanding structure of a quarter circle arc. The first fluid channels B5 and the second fluid channels D7 are distributed pairwise opposite to each other, and the first fluid channels B5 and the second fluid channels D7 are not connected to each other. The fact that both the first fluid channel B5 and the second fluid channel D7 are provided in two numbers is also for improving the discharging or feeding speed of the fluid. The first fluid outlet 6 can be provided at the side or bottom of the first fluid channel B5. In this embodiment, the first fluid outlet 6 is preferably provided at the bottom of the first fluid channel B5.

[0048] As Figure 7 shown, in some embodiments of the present invention, the projections of the first fluid channel A41 and the first fluid channel B5 in the axial direction of the housing 1 are distributed at 90°, that is, the projections of each first fluid channel A41 and each first fluid channel B5 in the axial direction of the housing 1 differ by 90° in distribution. Similarly, the projections of each second fluid channel C42 and each second fluid channel D7 in the axial direction of the housing 1 also differ by 90° in distribution. The purpose of such a setting is to increase the flow path of the fluid in the flow channel, thereby improving the heat exchange efficiency.

[0049] As Figure 3 shown, in some other embodiments of the present invention, a plurality of first inlets 411 are provided on the first fluid channel A41 and are distributed in the up and down direction. The plurality of first inlets 411 are respectively in one-to-one correspondence and communication with the odd-layer flow channels of the plate bundle unit 2, so that the fluid in the first fluid channel A41 can be dispersed into each odd-layer flow channel. Similarly, a plurality of second inlets 422 are provided on the second fluid channel C42 and are distributed in the up and down direction. The plurality of second inlets 422 are respectively in one-to-one correspondence and communication with the even-layer flow channels of the plate bundle unit 2.

[0050] To further improve the convective heat transfer during the heat exchange process, as Figure 1 and Figure 5 shown, in some embodiments of the present invention, a turbine 10 is provided in the space between the top of the plate bundle unit 2 and the top of the housing 1. A motor 11 is provided at the top of the housing 1, and the motor 11 is drivingly connected to the turbine 10. The space between the top of the plate bundle unit 2 and the top of the housing 1 communicates with the first fluid inlet 3 and the first fluid passage A41. In this embodiment, the motor 11 drives the turbine 10 to rotate clockwise or counterclockwise. The first fluid inlet 3 is provided with two, and the first fluid inlet 3 is arranged in an inclined direction consistent with the rotation direction of the turbine 10, so that the flow direction of the fluid entering the first fluid inlet 3 is consistent with the rotation direction of the turbine 10. Under the combined action of the inclined direction of the first fluid inlet 3 and the rotation direction of the turbine 10, the fluid is propelled to rotate, causing the fluid to form a turbulent state in the device. Turbulence can significantly improve the heat transfer efficiency, and turbulence can reduce the generation of flow separation and dead zones, thereby maintaining flow stability. In a system with a large temperature difference, turbulence helps to accelerate the convective heat transfer. The complex flow structure caused by turbulence increases the turbulent energy in the fluid, thus accelerating the heat exchange between different temperature regions.

[0051] In this embodiment, the hot fluid enters from the first fluid inlet 3. Under the action of the inclined direction of the first fluid inlet 3 and the rotation direction of the turbine 10, a turbulent state is formed in the hot fluid domain. The hot fluid will sequentially enter the odd-numbered laminar flow channels, forming an interleaved arrangement with the high-viscosity cold fluid. The hot fluid flows from the middle of the plate 21 towards the edge, thereby completing the heat exchange, and the heat is recovered through the first fluid outlet 6.

[0052] In some other embodiments, both the first fluid passage B5 and the second fluid passage D7 are of a gradually expanding structure with a quarter-circle arc, and the gradually expanding structure is tangent to the side wall of the housing 1. The spiral direction formed by the first fluid passage B5 and the second fluid passage D7 is consistent with the rotation direction of the turbine 10. The second fluid inlet 8 is preferably arranged on the end face of the gradually expanding structure of the second fluid passage D7 and is tangent to the housing 1. The high-viscosity cold fluid enters simultaneously from the relatively arranged second fluid inlets 8 to form a vortex state. The high-viscosity cold fluid rotates in the even-numbered laminar flow channels, quickly exchanges heat, and efficiently sterilizes. It enters from the edge of the plate 21 and is output from the center of the plate 21, thereby completing the sterilization of the high-viscosity cold fluid material.

[0053] As Figure 2As shown, in some embodiments of the present invention, the corrugations of each plate 21 are sinusoidal function corrugations, and the direction of the sinusoidal function corrugations extends from the center of the housing 1 to the edge. A plurality of reinforcing ribs 12 arranged in the radial direction are further provided on each plate 21, and the plurality of reinforcing ribs 12 are evenly distributed in a circumferential manner with the axis of the housing 1 as the center line. The reinforcing ribs 12 are arranged in a semi-circular protrusion structure. The corrugated structure of the plate 21 provides radial disturbance to the fluid, and the reinforcing ribs 12 provide axial disturbance to the fluid. Under the action of the double disturbance, the heat exchange efficiency is further improved.

[0054] As Figure 1 and Figure 2 shown, in some embodiments of the present invention, the funnel-type sterilization device applied to high-viscosity fluids further includes a material storage tank 13 provided at the bottom of the housing 1. The material storage tank 13 is communicated with the second fluid outlet 9, and the material storage tank 13 is used to store the cooled fluid after heat exchange. The funnel-type sterilization device applied to high-viscosity fluids further includes a base 14 provided at the bottom of the housing 1. The base 14 can be set as a square frame structure, or as Figure 1 shown, the base 14 is set as a cylindrical structure, and arc-shaped weight-reducing holes are provided on both the side wall and the center.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
