Description

Technical Field

[0001] This invention relates to the field of heat exchange device technology, specifically a heat exchange device, which belongs to the category of energy-saving heat exchange devices. Background Technology

[0002] Spiral plate heat exchangers are widely used in chemical, petroleum refining, food, and wastewater treatment industries. The spiral plate heat exchanger consists of two metal plates wound into a spiral shape, forming two concentric spiral channels for hot and cold fluids to flow in counter-current or parallel flow. The spiral geometry induces turbulence, improves the heat transfer coefficient, and has a heat transfer efficiency superior to traditional tubular heat exchangers.

[0003] Scaling on the metal plates of a spiral plate heat exchanger can lead to a decrease in heat exchange efficiency. Furthermore, the fouling or scaling can narrow the spiral channels, increase the pressure drop of the heat exchanger, and require higher pumping power to keep the fluid flow rate constant, resulting in increased energy consumption.

[0004] Descaling of spiral plate heat exchangers typically involves using descaling agents or high-pressure water jets. Descaling agents clean the scale buildup on the metal plates, but this poses a risk of corrosion and generates wastewater that requires additional neutralization or filtration equipment, increasing treatment costs. High-pressure water jet cleaning requires disassembly of the equipment, which is time-consuming, increasing safety risks and labor costs. Furthermore, the narrow and winding path of the spiral channel makes it difficult for the high-pressure water jet to penetrate deeply, making operation inconvenient. Cleaning also consumes a large amount of water and electricity, further increasing descaling costs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a heat exchange device in which the scaling location can be exposed, making scaling cleaning convenient and reducing water and energy consumption.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a heat exchange device, comprising a housing, wherein a receiving cavity is provided inside the housing, and a support tube one, a support tube two, and a flow guiding assembly are provided inside the receiving cavity. The support tube one and the support tube two are rotatably mounted on the inner wall of the receiving cavity. The support tube one is provided with an inner groove one and an inner groove two, and the support tube two is provided with an inner groove three and an inner groove four. Both ends of the support tube one and both ends of the support tube two penetrate the housing and extend to the outside of the housing.

[0007] The flow guiding component includes a first soft support strip and a second soft support strip arranged in parallel. Both the first soft support strip and the second soft support strip are fixedly connected to the strip-shaped soft bag body, and several support members are fixed between the first soft support strip and the second soft support strip.

[0008] One end of the soft bag is connected to the inner groove, and the other end of the soft bag is connected to the inner groove.

[0009] The flow guiding component is wound around the support tube one and the support tube two, and both the soft support strip one and the soft support strip two are slidably connected to the inner wall of the accommodating cavity.

[0010] The soft bag between the soft support strip one and the soft support strip two is taut, and the width of the inner cavity of the soft bag in the radial direction of the support tube one is smaller than the width of the soft support strip one in the radial direction of the support tube one and the width of the soft support strip two in the radial direction of the support tube one.

[0011] As a preferred embodiment of the present invention, it further includes an ultrasonic cleaner, wherein the ultrasonic transducer of the ultrasonic cleaner is located in the accommodating cavity of the housing, and the bottom side of the housing is provided with a drain hole and an inlet hole communicating with the accommodating cavity.

[0012] As a preferred embodiment of the present invention, an observation hole is provided on the housing, and a transparent plate is installed on the observation hole.

[0013] As a preferred embodiment of the present invention, both ends of the first support tube and both ends of the second support tube are equipped with rotary joints.

[0014] As a preferred embodiment of the present invention, both the first and second soft support strips are provided with bendable positioning elements, each comprising a plurality of connecting plates, with adjacent connecting plates being rotatably connected.

[0015] In this configuration, any one of the connecting plates is connected to at least one support member.

[0016] As a preferred embodiment of the present invention, the housing includes a hollow support shell with two mounting holes. One mounting hole is detachably mounted with a mounting plate one, and the other mounting hole is detachably mounted with a mounting plate two.

[0017] The soft support strip one and the mounting plate two are slidably attached together.

[0018] In a preferred embodiment of the present invention, the support member is a support rod or a support plate.

[0019] As a preferred embodiment of the present invention, the width of the inner cavity of the soft bag in the radial direction of the support tube is 1.0cm-5.0cm, the width of the soft support strip in the radial direction of the support tube is 2.0cm-10.0cm, and the ratio of the width of the inner cavity of the soft bag in the radial direction of the support tube to the width of the soft support strip in the radial direction of the support tube is 1.0:1.5-3.0, and the distance between any two adjacent support members is 1.0cm-10.0cm.

[0020] As a preferred embodiment of the present invention, both the first soft support strip and the second soft support strip are made of flexible magnetic material.

[0021] As a preferred embodiment of the present invention, both the first support tube and the second support tube are fixed with guide support arc plates that support the first soft support strip and the second soft support strip.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. The heat exchange device of this invention, on the one hand, when the soft bag moves between support tube one and support tube two, the soft bag changes from a bent state to a straight state. The wrinkles of the soft bag that are not wrapped around support tube one and support tube two are flattened and the taut positions return to an untaut state, making the adhesion of scale on the soft bag worse. The operator uses a high-pressure water gun to rinse the soft bag between support tube one and support tube two, making it easy to clean the scale on the soft bag. On the other hand, the ultrasonic transducer of the ultrasonic cleaner is located in the accommodating cavity of the shell. The ultrasonic transducer of the ultrasonic cleaner removes the scale on the soft bag, and the fluid flowing in the accommodating cavity discharges the removed scale from the accommodating cavity. This allows for descaling without stopping the machine, ensuring heat exchange efficiency, saving energy and reducing consumption, and reducing the safety risks and labor costs of descaling operations.

[0024] 2. In the heat exchange device of the present invention, the winding direction of the soft bag on the first support tube is the same as the winding direction of the soft bag on the second support tube. The soft bag between the first support tube and the second support tube is taut, so that the high-frequency sound waves generated by the ultrasonic transducer can act on both sides of the soft bag, thereby improving the descaling efficiency.

[0025] 3. In the heat exchange device of the present invention, the operator adds pigment to fluid one, and then the operator rotates support tube one or support tube two. The operator observes the leakage point on the soft bag through the transparent plate, which facilitates the operator to locate the leakage point of the soft bag and to seal the leakage point.

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] Example 1:

[0036] Please see Figures 1-7 This embodiment discloses a heat exchange device, including a housing 1. The housing 1 has a receiving cavity, and a support tube 3, a support tube 5, and a flow guiding assembly 6 are arranged in the receiving cavity. The support tube 3 and the support tube 5 are respectively installed on the inner wall of the receiving cavity through a sealed bearing or a rotating shaft seal. The support tube 3 has a non-communicating inner groove 301 and an inner groove 302, and the support tube 5 has a non-communicating inner groove 301 and an inner groove 402. Both ends of the support tube 3 and the support tube 5 penetrate the housing 1 and extend to the outside of the housing 1.

[0037] The flow guiding component 6 includes a first soft support strip 601 and a second soft support strip 603 arranged in parallel. A strip-shaped soft bag body 604 is provided between the first soft support strip 601 and the second soft support strip 603. The first soft support strip 601 and the second soft support strip 603 are both bonded to the soft bag body 604 or ultrasonically welded. Several support members 602 are fixed between the first soft support strip 601 and the second soft support strip 603.

[0038] One end of the soft bag 604 is connected to the inner groove 301, and the other end of the soft bag 604 is connected to the inner groove 502.

[0039] Among them, the flow guiding component 6 is wound around the support tube 3 and the support tube 5, and the soft support strip 601 and the soft support strip 603 are slidably connected to the inner wall of the accommodating cavity.

[0040] Among them, the soft bag body 604 between the soft support strip 601 and the soft support strip 603 is taut, and the width of the inner cavity of the soft bag body 604 in the radial direction of the support tube 3 is smaller than the width of the soft support strip 601 in the radial direction of the support tube 3 and the width of the soft support strip 603 in the radial direction of the support tube 3.

[0041] Furthermore, the housing 1 includes a hollow support shell 102, which has a first side and a second side arranged opposite to each other. Mounting holes are respectively provided on the first side and the second side opposite to it. Mounting plate 101 can be detachably installed on one of the mounting holes, and mounting plate 103 can be detachably installed on the other mounting hole.

[0042] Among them, soft support strip 601 and mounting plate 103 are slidably attached.

[0043] Furthermore, the width of the inner cavity of the soft bag body 604 in the radial direction of the support tube 3 is 1.0cm-5.0cm, the width of the soft support strip 601 in the radial direction of the support tube 3 is 2.0cm-10.0cm, and the ratio of the width of the inner cavity of the soft bag body 604 in the radial direction of the support tube 3 to the width of the soft support strip 601 in the radial direction of the support tube 3 is 1.0:1.5-3.0, and the distance between any two adjacent support members 602 is 1.0cm-10.0cm.

[0044] Furthermore, the support member 602 is a support rod or a support plate.

[0045] Furthermore, the support shell 102, mounting plate one 101 and mounting plate two 103 are all made of metal.

[0046] Furthermore, the winding direction of the soft bag 604 on the support tube 3 is the same as the winding direction of the soft bag 604 on the support tube 5, and the soft bag 604 between the support tube 3 and the support tube 5 is taut.

[0047] The working process and principle of this embodiment are as follows:

[0048] Workers input fluid one into the inner cavity of the soft bag 604 through the inner groove 301 of support tube one 3 or the inner groove 502 of support tube two 5. Workers input fluid two into the space between the outer side of the soft bag 604 and the inner wall of the accommodating cavity through the inner groove 301 of support tube two 5 or the inner groove 302 of support tube one 3. The flow direction of fluid one is opposite to that of fluid two, so that fluid one and fluid two maintain a large temperature difference during the flow process, thereby increasing the total amount of heat transfer per unit time.

[0049] Fluid 1 is the heating medium and fluid 2 is the heated medium, or fluid 1 is the heated medium and fluid 2 is the heating medium, with fluid 2 being a fluid more prone to scaling than fluid 1.

[0050] When the soft bag 604 is wrapped around the support tube 3 or the support tube 5, the inner side of the soft bag 604 shrinks and wrinkles, and the outer side of the soft bag 604 is stretched and tightened.

[0051] When excessive scale buildup occurs on the outer side of the soft bag 604, the operator removes mounting plate 101 or mounting plate 103 from the support shell 102. The operator then rotates support tube 3 to increase the number of flow guide components 6 wound on it, or rotates support tube 25 to increase the number of flow guide components 6 wound on it. When the soft bag 604 moves between support tube 3 and support tube 25, it changes from a bent state to a straight state. The folds of the soft bag 604 not wound on support tube 3 and support tube 25 are flattened, and the taut parts return to an untaut state, making the scale adhesion on the soft bag 604 worse. The operator then uses a high-pressure water gun to rinse the soft bag 604 between support tube 3 and support tube 25, making it easier to clean the scale on the soft bag 604.

[0052] Preferably, the soft bag body 604 is made of soft rubber, soft plastic, or fiber cloth coated with thermally conductive resin, and the soft bag body 604 is waterproof.

[0053] Example 2:

[0054] like Figures 1-7 As shown, this embodiment discloses a heat exchange device, including a housing 1 and an ultrasonic cleaner 7. The housing 1 has a receiving cavity, and a support tube 3, a support tube 5, and a flow guiding component 6 are arranged in the receiving cavity. The support tube 3 and the support tube 5 are respectively installed on the inner wall of the receiving cavity through a sealed bearing or a rotating shaft seal. One end of the support tube 3 has an inner groove 301, and the other end of the support tube 3 has an inner groove 302. One end of the support tube 5 has an inner groove 501, and the other end of the support tube 5 has an inner groove 502. Both ends of the support tube 3 and the support tube 5 penetrate the housing 1 and extend to the outside of the housing 1.

[0055] The flow guiding component 6 includes a first soft support strip 601 and a second soft support strip 603 arranged in parallel. Both the first soft support strip 601 and the second soft support strip 603 are bonded to or ultrasonically welded to the strip-shaped soft bag body 604. Several support members 602 are fixed between the first soft support strip 601 and the second soft support strip 603.

[0056] One end of the soft bag 604 is connected to the inner groove 301, and the other end of the soft bag 604 is connected to the inner groove 502.

[0057] Among them, the flow guiding component 6 is wound around the support tube 3 and the support tube 5, and the soft support strip 601 and the soft support strip 603 are slidably connected to the inner wall of the accommodating cavity.

[0058] Among them, the soft bag body 604 between the soft support strip 601 and the soft support strip 603 is taut, and the width of the inner cavity of the soft bag body 604 in the radial direction of the support tube 3 is smaller than the width of the soft support strip 601 in the radial direction of the support tube 3 and the width of the soft support strip 603 in the radial direction of the support tube 3.

[0059] The ultrasonic transducer of the ultrasonic cleaner 7 is located in the accommodating cavity of the housing 1. The bottom side of the housing 1 is provided with a drain hole 104 and an inlet hole 105 that communicate with the accommodating cavity.

[0060] Furthermore, the ultrasonic transducer of the ultrasonic cleaner 7 is located on the bottom side of the accommodating cavity, and the ultrasonic transducer of the ultrasonic cleaner 7 is located between the support tube 3 and the support tube 5.

[0061] Furthermore, rotary joints 4 are installed at both ends of support tube 3 and support tube 5.

[0062] The ultrasonic cleaner 7 used in this invention is a commonly used device in the prior art. Its working method and circuit structure are well known technologies and will not be described in detail here.

[0063] The working process and principle of this embodiment are as follows:

[0064] Workers input fluid one into the inner cavity of the soft bag 604 through the inner groove 301 of support tube one 3 or the inner groove 502 of support tube two 5. Workers input fluid two into the space between the outer side of the soft bag 604 and the inner wall of the accommodating cavity through the inner groove 301 of support tube two 5 or the inner groove 302 of support tube one 3. The flow direction of fluid one is opposite to that of fluid two, so that fluid one and fluid two maintain a large temperature difference during the flow process, thereby increasing the total amount of heat transfer per unit time.

[0065] Fluid 1 is the heating medium and fluid 2 is the heated medium, or fluid 1 is the heated medium and fluid 2 is the heating medium. Fluid 2 is a fluid that is more prone to scaling than fluid 1, and fluid 2 is liquid.

[0066] When the soft bag 604 is wrapped around the support tube 3 or the support tube 5, the inner side of the soft bag 604 shrinks and wrinkles, and the outer side of the soft bag 604 is stretched and tightened.

[0067] When excessive scale buildup occurs on the outer side of the soft bag 604, the operator manually rotates it or an external motor drives the support tube 3 or support tube 5 to rotate. The operator then operates the ultrasonic cleaner 7. The ultrasonic transducer of the ultrasonic cleaner 7 generates high-frequency sound waves in the fluid, causing the scale on the soft bag 604 to detach.

[0068] The drain hole 104 is connected to the external drain pipe, and the inlet hole 105 is connected to the external inlet pipe. The operator continuously pumps the external liquid pump into the accommodating cavity through the external inlet pipe and the inlet hole 105. The fluid 2 in the accommodating cavity is discharged through the drain hole 104 and the external drain pipe. The fluid 2 flowing in the accommodating cavity causes the scale detached from the soft bag 604 to be discharged from the accommodating cavity. The operator filters the discharged fluid 2 containing scale.

[0069] This heat exchange device can perform descaling without shutting down the machine, ensuring heat exchange efficiency, saving energy and reducing consumption, and lowering the safety risks and labor costs of descaling operations.

[0070] Furthermore, the winding direction of the soft bag 604 on the support tube 3 is the same as the winding direction of the soft bag 604 on the support tube 5. The soft bag 604 between the support tube 3 and the support tube 5 is tightened, so that the high-frequency sound waves generated by the ultrasonic transducer can act on both sides of the soft bag 604, thereby improving the descaling efficiency.

[0071] Furthermore, when the rotary joint 4 rotates the support tube 3 and the support tube 5, fluid 1 and fluid 2 still maintain relative flow within the accommodating cavity.

[0072] Furthermore, since fluid one is liquid, when the gas introduced by fluid one accumulates in the soft bag 604, the gas will block the flow channel and increase the pumping energy consumption of fluid one. The operator can rotate the support tube 3 or the support tube 5 to facilitate the discharge of gas in the soft bag 604.

[0073] Example 3:

[0074] like Figure 1 and Figure 2 As shown, this embodiment discloses a heat exchange device, whose structure is roughly the same as that of Embodiment 2. The difference is that an observation hole is provided on the shell 1 of this embodiment, and a transparent plate 2 is installed on the observation hole.

[0075] The working process and principle of this embodiment are as follows:

[0076] Through the transparent plate 2, staff can observe the soft bag 604 wrapped around the support tube 1 3 and the soft bag 604 wrapped around the support tube 2 5. Staff can also observe the scaling on the soft bag 604 and the effect of cleaning the scaling on the soft bag 604 through the transparent plate 2.

[0077] When fluid one is in a liquid state, the staff adds pigment to fluid one, and then the staff rotates support tube one 3 or support tube two 5. The staff observes the leakage point on the soft bag body 604 through the transparent plate 2, which makes it easier for the staff to locate the leakage point of the soft bag body 604 and to seal the leakage point.

[0078] Example 4:

[0079] like Figure 7 As shown, this embodiment discloses a heat exchange device, whose structure is roughly the same as that of Embodiment 1 or Embodiment 2. The difference is that both the soft support bar 1 601 and the soft support bar 2 603 in this embodiment are provided with flexible positioning members 605. The positioning member 605 includes several connecting plates, and any two adjacent connecting plates are connected by a hinge seat or a rotating pin.

[0080] In this configuration, any one of the connecting plates is connected to at least one support member 602.

[0081] Furthermore, both soft support strip 1 (601) and soft support strip 2 (603) are made of elastic rubber.

[0082] The working process and principle of this embodiment are as follows:

[0083] Positioning element 605 allows both soft support strip 1 601 and soft support strip 2 603 to slide against the inner wall of the accommodating cavity.

[0084] Example 5:

[0085] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment discloses a heat exchange device, whose structure is roughly the same as that of Embodiment 2. The difference is that the housing 1 of this embodiment includes a hollow support shell 102. The support shell 102 has a first surface and a second surface that are arranged opposite to each other. Mounting holes are respectively opened on the first surface and the second surface opposite to it. Mounting plate 101 can be detachably installed on one of the mounting holes, and mounting plate 103 can be detachably installed on the other mounting hole.

[0086] Among them, soft support strip 601 and mounting plate 103 are slidably attached.

[0087] Furthermore, the support shell 102, mounting plate one 101 and mounting plate two 103 are all made of metal.

[0088] The working process and principle of this embodiment are as follows:

[0089] Mounting plate 101 and mounting plate 203 facilitate the installation and disassembly of support tube 13 and support tube 25, and make it easier for workers to repair any damage to the soft bag body 604.

[0090] Example 6:

[0091] like Figure 2 and Figure 7As shown, this embodiment discloses a heat exchange device, the structure of which is roughly the same as that of Embodiment 1 or Embodiment 2. The difference is that in this embodiment, both the soft support bar 601 and the soft support bar 603 are made of flexible magnetic material, and the shell 1 is made of iron-containing metal plate material.

[0092] The working process and principle of this embodiment are as follows:

[0093] The soft support strip 601 and the soft support strip 603 are magnetically attached to the inner wall of the accommodating cavity, enhancing the sealing between the soft support strip 601 and the inner wall of the accommodating cavity, and between the soft support strip 603 and the inner wall of the accommodating cavity.

[0094] Example 7:

[0095] like Figure 2 , Figure 5 and Figure 6 As shown, this embodiment discloses a heat exchange device, the structure of which is roughly the same as that of Embodiment 1 or Embodiment 2. The difference is that in this embodiment, both the support tube 1 3 and the support tube 2 5 are fixed with guide support arc plates 8 to support the soft support strip 1 601 and the soft support strip 2 603, so as to avoid the bending angle of the soft bag 604 being too large and to keep the pressure drop of the soft bag 604 within the set range.

[0096] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
