[0002] In the industrial production process, many chemical reactions will release a large amount of heat energy, causing the temperature of the reaction materials to rise. Or for some physical processing processes, such as metal smelting, ore roasting, etc., the materials need to be heated to a higher temperature for effective processing. This causes the materials produced by the reactor or reactor to often have a higher temperature. For example, in the field of zircon sand production and processing, the heated zircon sand is in liquid form, and its main component is sodium zirconate.

Specific embodiments

[0017] Here, the technical solutions in the embodiments (or "embodiment modes") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description involves the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0018] If there are terms related to directional indications or positional relationships in the embodiments of this application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), then such terms are only used to explain the relative positional relationships, motion conditions, etc. between components in a specific posture (as shown in the attached drawings); if the specific posture changes, then the directional indication or positional relationship also changes accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of this application are only for the purpose of convenient description and cannot be understood as indicating or implying relative importance.

[0019] Please refer to Figure 1 and Figure 5 , Figure 1 is an internal schematic view of the energy-saving corrugated pipe material transportation and heat exchange device. Figure 5 is a partial schematic view of the inside of the heat exchange chamber. The present application provides an energy-saving corrugated pipe material transportation and heat exchange device, including a material transportation chamber 100, a heat exchange chamber 200, a cold air pipe group 300, a corrugated heat exchange pipe group 400, and a flow disturbance component 500. Combining Figure 2 , Figure 3 and Figure 4 , Figure 2 is a front view of the energy-saving corrugated pipe material transportation and heat exchange device. The material transportation chamber 100 is used to transport the material a in the production process, and the material transportation chamber 100 extends along the material transportation direction X. Taking the production and processing of zircon sand as an example, the material a here is the heated zircon sand, with the main component being sodium zirconate, and it is transported to the water washing and sodium removal device through the material transportation chamber 100.

[0020] Combining Figure 5 , Figure 6 and Figure 7 , Figure 6 is a front view of the flow disturbance component, Figure 7 is a side view of the flow disturbance component. The heat exchange chamber 200 is adjacent to the material transportation chamber 100, and the heat exchange chamber 200 shares at least the first wall surface 110 with the material transportation chamber 100. The first wall surface 110 is the surface of the material transportation chamber 100 parallel to the material transportation direction X, specifically one or more surfaces such as the top surface, side surface, etc. of the material transportation chamber 100, and the heat exchange chamber 200 is used to introduce a coolant. Among them, the coolant can be cooling water, ethylene glycol-based coolant, oil-based coolant, etc. Since the first wall surface 110 is shared by the material transportation chamber 100 and the heat exchange chamber 200, the heat exchange chamber 200 can introduce the coolant to exchange heat with the material transportation chamber 100 through the first wall surface 110, thereby having a certain cooling effect on the material a in the material transportation chamber 100.

[0021] Combining Figure 1 and Figure 8 , Figure 8It is a schematic diagram of the pipeline inside the heat exchange chamber. The cold air duct group 300 is connected to the material transportation chamber 100 and is used to introduce cooling air into the material transportation chamber 100. The cooling air directly contacts the material a to cool the material a.

[0022] Combined with Figure 1 、 Figure 5 and Figure 8 ,the corrugated heat exchange tube group 400 is distributed in the heat exchange chamber 200. At least part of the pipeline is arranged at a position adjacent to the first wall surface 101. The corrugated heat exchange tube group 400 is connected to the material transportation chamber 100. The cooling air introduced into the material transportation chamber 100 by the cold air duct group 300 flows through the material transportation chamber, exchanges heat with the material a, and then enters the corrugated heat exchange tube group 400, where it exchanges heat with the coolant in the heat exchange chamber 200. After the cold air exchanges heat with the material a and becomes hot air, it enters the corrugated heat exchange tube group 400 again. Since the coolant directly contacts the corrugated heat exchange tube group 400, heat exchange can be carried out on the hot air in the corrugated heat exchange tube group 400, so that the coolant can further cool the corrugated heat exchange tube group 400, making the cooling capacity of the coolant more fully utilized, improving the heat exchange efficiency and being more energy-saving. Then the heat-exchanged gas is introduced into subsequent industrial recovery or anti-pollution and other treatment processes, eliminating the cooling device for the corrugated heat exchange tube group 400. As a heat exchange tube, the corrugated tube, through its unique wave crest and wave trough design, makes the fluid form strong turbulence inside and outside the tube, thus destroying the boundary layer and improving the heat transfer coefficient and heat exchange efficiency. It should be noted that Figure 8 、 Figure 9 、 Figure 10 and Figure 11 the corrugated heat exchange tube group in does not show the shape characteristics of the corrugated tube, but shows the position characteristics and arrangement characteristics of the corrugated tube. Among them Figure 9 is the side view of the corrugated heat exchange tube group, Figure 10 is the front view of the pipeline inside the heat exchange chamber, Figure 11 is the side view of the pipeline inside the heat exchange chamber.

[0023] Combined with Figure 5 、 Figure 6 and Figure 7, the spoiler assembly 500 is inserted through the first wall surface 110 and includes a first end 501 and a second end 502. The first end 501 extends into the heat exchange chamber 200, and the second end 502 extends into the material transportation chamber 100. A first impeller 510 is connected to the first end 501, and a second impeller 520 is connected to the second end 502. The first impeller 510 and the second impeller 520 are drivingly connected. The second impeller 520 is driven by the cooling air in the material transportation chamber 100 to drive the first impeller 510 to rotate in the heat exchange chamber 200 to disrupt the laminar flow of the coolant. This disturbance makes the flow of the coolant more complex, destroys the stability of the boundary layer, thereby increasing the contact area and contact frequency between the coolant and the corrugated heat exchange tube group 400. The disturbed coolant can absorb heat more efficiently, significantly improving the heat exchange efficiency. Moreover, the second impeller 520 is driven by the cooling air in the material transportation chamber 100, and this passive drive design does not require additional electrical power or other energy input. Compared with traditional active stirring or pump drive systems, this design can significantly reduce energy consumption and lower the operating cost.

[0024] In summary, first, in the present application, the material transportation chamber 100 can be preliminarily cooled by the coolant through the direct contact between the heat exchange chamber 200 and the material transportation chamber 100, and then the material a can be further directly cooled by the cooling air directly blown onto the material a; afterwards, the hot air generated after heat exchange with the material a passes through the corrugated heat exchange tube group 400 in the heat exchange chamber 200 to exchange heat with the coolant again, making full use of the cold quantity of the coolant while cooling the hot air in the corrugated heat exchange tube group 400 and directly treating the hot air after heat exchange. Finally, for the spoiler assembly 500, using the wind energy of the cooling air blowing towards the material a, it stirs the coolant in the heat exchange chamber 200, rotates to disrupt the laminar flow of the coolant, improves the heat exchange efficiency between the coolant and the corrugated heat exchange tube group 400, achieves full heat exchange, and is also more energy-efficient.

[0025] In a specific embodiment, referring to Figure 1 、 Figure 3 and Figure 4 , Figure 3 is an external schematic diagram of the energy-saving corrugated tube material transportation and heat exchange device, Figure 4It is a top view of the energy-saving corrugated pipe material transportation and heat exchange device. A coolant inlet 201 and a coolant outlet 202 are also provided on the heat exchange chamber 200, which can be arranged at both ends of the heat exchange chamber 200 along the material transportation direction X, and the coolant inlet 201 is at the discharging end of the material transportation chamber 100, and the coolant outlet 202 is at the feeding end of the material transportation chamber 100. First, it can ensure that the coolant fully covers the material transportation path of the material transportation chamber 100, and more fully cools the material a in the material transportation chamber 100. The material a at the discharging end is lower in temperature than the material a at the feeding end, and the temperature of the coolant at the coolant inlet 201 is also lower than that at the coolant outlet 202, so that it can ensure that the temperature of the coolant is consistent with the temperature change of the material a, ensuring a better cooling effect.

[0026] In one embodiment, referring to Figure 1 and Figure 8 , the cold air duct group 300 is communicated with the material transportation chamber 100 through the first cold air outlet 301, and the windward surface of the second impeller 520 faces the plane where the first cold air outlet 301 is located. The first cold air outlet 301 can be provided with a plurality of them, and are distributed along the material transportation direction X, uniformly and fully introducing cold air into the entire material transportation chamber 100. When the cold air enters the material transportation chamber 100 through the first cold air outlet 301, it faces the windward surface of the second impeller 520, so that the cold air can directly impact the second impeller 520, thereby more efficiently transferring the energy of the cooling air to the second impeller 520 and driving the second impeller 520 to rotate. This facing setting can reduce the loss of the energy of the cooling air.

[0027] In one embodiment, in combination with Figure 5 , Figure 6 and Figure 7 , the first impeller 510 is arranged parallel to the first wall surface 110 and is arranged at the middle position of the first wall surface 110. The first impeller 510 arranged in parallel can better adapt to the flow direction of the coolant, reduce the resistance when the fluid enters the impeller, and can push the coolant towards the bottom surface of the corrugated heat exchange pipe group 400, so that the coolant can contact the corrugated heat exchange pipe group 400 more fully, improving the cooling efficiency. When arranged at the middle position of the first wall surface 110, the rotation of the first impeller 510 can evenly disturb the flow of the coolant in the heat exchange chamber 200. This layout makes the turbulent flow distribution of the coolant in the central area of the heat exchange chamber more uniform.

[0028] The first impeller 510 is vertically arranged relative to the first wall surface 110 and is arranged at the edge position of the first wall surface 110; the vertically arranged first impeller 510 can change the flow direction of the coolant fluid. For example, if the coolant flows parallel to the first wall surface 110, the vertically arranged first impeller 510 can interrupt the flow of the coolant and push the coolant towards the corrugated heat exchange tube group 400, so that the coolant can contact the corrugated heat exchange tube group 400 more fully, improving the heat exchange efficiency. The first impeller 510 is inclined relative to the first wall surface 110 and is arranged at the edge position of the first wall surface 110. Similarly, the inclined first impeller 510 can also push towards the corrugated heat exchange tube group 400, so that the coolant can contact the corrugated heat exchange tube group 400 more fully, improving the heat exchange efficiency. Specifically, whether the first impeller 510 is vertically arranged or inclined can be designed according to the position and shape of the corrugated heat exchange tube group 400 relative to the first wall surface 110. Further, the first impeller 510 is vertically or inclined relative to the first wall surface 110, which helps to break the flow dead zone at the edge of the coolant and improve the heat exchange efficiency.

[0029] In one embodiment, in combination with Figure 5 、 Figure 6 and Figure 7 , the flow disturbance component 500 includes a housing 530, a gear transmission component (not shown in the figure) arranged inside the housing. The first impeller 510 and the second impeller 520 are connected through the gear transmission component. The first impeller 510 and the second impeller 520 are respectively rotatably connected to the housing 530 through dynamic seal components 540. Among them, the gear transmission component is designed according to the relative position relationship between the first impeller 510 and the second impeller 520. For example, if the first impeller 510 is parallel to the first wall surface 110 and the second impeller 520 is perpendicular to the first wall surface 110, then the first impeller 510 and the second impeller 520 are perpendicular to each other. The gear transmission component at least includes two meshing bevel gear components, worm and worm gear components, and helical gear components, etc. The dynamic seal component 540 can achieve sealing while the first impeller 510 and the second impeller 520 can rotate relative to the housing 530. Specifically, the dynamic seal component 540 can be a double-ended mechanical seal structure, etc. The double-ended mechanical seal realizes double sealing through two groups of dynamic / static rings, compensation mechanisms and auxiliary systems.

[0030] In one embodiment, in combination with Figure 1 、 Figure 2 and Figure 3, the material transportation chamber 100 includes a first side wall 111, a second side wall 112, and a top wall 113 parallel to the material transportation direction X. The first wall surface 110 is the top wall 113. The first side wall 111 and the second side wall 112 are also shared with the heat exchange chamber 200 and are oppositely arranged. That is, except for the bottom surface of the material transportation chamber 100 and the two ends for feeding and discharging, other wall surfaces are shared with the heat exchange chamber 200. Such an arrangement can increase the heat exchange surface in direct contact between the heat exchange chamber 200 and the material transportation chamber 100, improve the heat exchange efficiency. When the material a moves along the material transportation direction X in the material transportation chamber 100, heat can be quickly conducted to the heat exchange chamber 200 through the shared side walls and the top wall, reducing the temperature of the material a. And with such an arrangement, the volume of the heat exchange chamber 200 will be larger, enabling the corrugated heat exchange tube group 400 to have a larger space for layout and a larger area for laying, increasing the heat exchange efficiency between the corrugated heat exchange tube group 400 and the coolant.

[0031] In one embodiment, referring to Figure 1 and Figure 8 , the corrugated heat exchange tube group 400 communicates with the material transportation chamber 100 on the first side wall 111, and the cold air duct group 300 communicates with the material transportation chamber 100 on the second side wall 112. The first side wall 111 and the second side wall 112 are oppositely arranged, which can ensure that the air blown out by the cold air duct group 300 from the second side wall 112 passes directly through the material a in a straight line and is directly collected by the corrugated heat exchange tube group 400 on the first side wall 111. Such a design optimizes the air flow path, reduces the detour and energy loss of the cold air in the material transportation chamber 100, thereby improving the cooling efficiency.

[0032] The corrugated heat exchange tube group 400 is in the heat exchange chamber 200. Starting from the first side wall 111, it passes through the space opposite the top wall 113, and then returns to the space opposite the first side wall 111, and extends out from the wall surface of the heat exchange chamber 200 opposite the first side wall 111. That is, starting from the space opposite the first side wall 111, it makes a turn in the space opposite the top wall 113 and returns to the space opposite the first side wall 111. Such a design can enable the corrugated heat exchange tube group 400 to be laid in a larger area in the heat exchange chamber 200.

[0033] The cold air duct group 300 is distributed in the space opposite the second side wall 112 in the heat exchange chamber 200. With such an arrangement, the corrugated heat exchange tube group 400 and the cold air duct group 300 are distributed in two parts, reducing the heat exchange between the cold air duct group 300 and the corrugated heat exchange tube group 400, ensuring that the cold air of the cold air duct group 300 first exchanges heat with the material a to ensure the cooling effect on the material a.

[0034] In one embodiment, in combination with Figure 8 , Figure 9 , Figure 10 and Figure 11。The corrugated heat exchange tube group 400 includes multiple corrugated tubes arranged in parallel along the material conveying direction X; among them, three adjacent corrugated tubes form a group, including a first corrugated tube 410, a second corrugated tube 420, and a third corrugated tube 430, which are respectively communicated with the material conveying chamber 100 through a first air inlet 411, a second air inlet 421, and a third air inlet 431 opened on the first side wall 111, and respectively extend out of the heat exchange chamber 200 through a first air outlet 412, a second air outlet 422, and a third air outlet 432 opened on the wall surface of the heat exchange chamber 200 facing the first side wall 111; The first air inlet 411, the second air inlet 421, and the third air inlet 431 are respectively arranged at the upper, middle, and lower parts of the first side wall 111, and the first air outlet 412, the second air outlet 422, and the third air outlet 432 are respectively arranged at the lower, middle, and upper parts of the wall surface of the heat exchange chamber 200 facing the first side wall 111. With such a design of the three corrugated tubes in a group, firstly, from the layout of the air inlets, the three air inlets are respectively located at the upper, middle, and lower parts of the first side wall 111. Such a layout can ensure that the gas after heat exchange with the material a in the material conveying chamber 100 has channels to enter the corrugated heat exchange tube group 400 at different height positions, thus realizing the all-round and multi-level introduction of the heat-exchanged gas. And from the layout of the air outlets, the three air outlets are respectively arranged at the lower, middle, and upper parts of the wall surface of the heat exchange chamber 200 facing the first side wall 111. This forms an up-and-down dislocation with the positions of the three air inlets. This dislocation arrangement is beneficial to guiding the heat exchange gas to form a more complex flow path inside the corrugated tube, increasing the residence time of the gas in the tube and the tortuosity of the flow, and further enabling the gas to have more sufficient time and opportunity to exchange heat with the coolant in the corrugated tube, greatly improving the heat exchange efficiency. The corrugated heat exchange tube group 400 is composed of multiple groups of the first corrugated tube 410, the second corrugated tube 420, and the third corrugated tube 430 arranged along the material conveying direction X.

[0035] In a specific embodiment, in combination with Figure 2 、 Figure 4 and Figure 8 , the energy-saving corrugated tube material conveying and heat exchange device may further include an air collecting chamber 600. The corrugated heat exchange tube group 400 discharges the heat-exchanged gas from the air outlets on the wall surface of the heat exchange chamber 200 facing the first side wall 111. The air collecting chamber 600 can play a certain buffering role on the air flow, reduce the pulsation and fluctuation of the air flow, make the discharged gas flow rate more stable, and provide stable air flow conditions for subsequent gas treatment or emission. And it can make the relatively higher-temperature gas and the relatively lower-temperature gas mix with each other in the air collecting chamber 600. This mixing process gradually reduces the temperature difference between the gases, facilitating the unified waste heat recovery of these gases with a certain amount of waste heat.

[0036] In a specific embodiment, the cold air duct group 300 enters the material transportation chamber 100 through a plurality of first cold air inlets 301 on the second side wall 112, and the plurality of first cold air inlets 301 are arranged along the material transportation direction X. Cold air is introduced into the cold air duct group 300 through a second cold air inlet 302 opened on the wall surface of the heat exchange chamber 200 facing the second side wall 112. Each first cold air inlet 301 can be independently provided with a cold air regulating device for regulating the air volume and air speed, and flexibly adjusting according to the cooling requirements of different areas of the material transportation chamber 100. For example, the temperature of the material a near the feeding end is relatively high, and the air volume and air speed of the first cold air inlet 301 near the feeding end can be appropriately increased to enhance the cooling effect; while the temperature of the material a near the discharging end is relatively low, the air volume and air speed of the first cold air inlet 301 at the discharging end can be reduced to save energy. Designing a second cold air inlet 302 can reduce the ventilation resistance during air intake, making it easier for cold air to enter the cold air duct group 300 and improving the overall performance of the heat exchange device. The cold air regulating device can be realized by devices such as a regulating valve, an air volume regulating plate, and a variable frequency speed regulating fan.

[0037] In one embodiment, in combination with Figure 2 , a plurality of heat exchange heat rods 700 are inserted into the second side wall 112. One end of the heat exchange heat rod 700 extends into the material transportation chamber 100, and the other end is inserted into the heat exchange chamber 200. The outer shell of the heat exchange heat rod 700 is a sealed tubular structure made of metal, and components such as a working fluid and a wick are installed inside. The wick is a porous structure, such as a copper wire mesh or sintered metal powder, and its function is to provide capillary force for the working fluid to promote liquid reflux. Common working fluids include water, methanol, ammonia, etc. For example, in a low-temperature environment, low-boiling-point liquids such as methanol or ammonia can be used to ensure the normal operation of the heat exchange heat rod 700. The end of the working fluid extending into the material transportation chamber 100 will vaporize under the action of the high temperature in the material transportation chamber 100, and then will liquefy at the end extending into the heat exchange chamber 200 under the cooling action of the coolant. The heat exchange heat rod 700 uses the phase change cycle of the working fluid to achieve efficient heat transfer. In the above embodiment, the corrugated heat exchange tube group 400 is distributed in the space of the heat exchange chamber 200 facing the first side wall 111 and the top wall 113, and there is no corrugated heat exchange tube group 400 in the space facing the second side wall 112. Therefore, heat exchange heat rods 700 are provided on the second side wall 112 to further increase the heat exchange efficiency between the coolant in the heat exchange chamber 200 and the material transportation chamber 100. In addition, heat exchange heat rods 700 can also be provided on the first side wall 111 and the top wall 113 of the material transportation chamber 100. A plurality of heat exchange heat rods 700 can also be arranged in a row along the material transportation direction X and are inclined with respect to the opposite wall surface.

[0038] In one embodiment, with reference to FIGS. 2 and Figure 3, a heat insulation plate 210 is horizontally arranged between the second side wall 112 and the wall surface of the heat exchange chamber 200 parallel to the second side wall 112. The heat insulation plate 210 divides the heat exchange chamber 200 into a first cavity 200a and a second cavity 200b. The corrugated heat exchange tube group 400 is arranged in the first cavity 200a, and the first cavity 200a is used to introduce coolant. The cold air duct group 300 is arranged in the second cavity 200b. Since the cold air introduced into the cold air duct group 300 needs to first enter the material transportation chamber 100 to exchange heat with the material a, setting the heat insulation plate 210 can prevent the heat generated during the heat exchange process of the corrugated heat exchange tube group 400 from being directly transferred to the cavity where the cold air duct group 300 is located, which helps to maintain the temperature stability of the working environment of the cold air duct group 300, ensure that the cold air can continuously and stably provide cold air for the material transportation chamber 100, and guarantee the cooling effect of the material a. The heat insulation plate 210 can be made of materials with low thermal conductivity, such as glass fiber, silicate, etc.

[0039] Specifically, the coolant inlet 201 and the coolant outlet 202 are respectively communicated with the first cavity 200a, and only the coolant is introduced into the first cavity 200a. The coolant inlet 201 is arranged on the wall surface of the heat exchange chamber 200 facing the second side wall 112, and the coolant outlet 202 is arranged on the wall surface of the heat exchange chamber 200 facing the first side wall 111. Since the cold air duct group 300 is arranged in the space close to the second side wall 112, the temperature of the space facing the second side wall 112 is lower than the temperature of the space facing the first side wall 111, and the temperature of the coolant inlet 201 is lower than the temperature of the coolant outlet 202. Such an arrangement can ensure that the temperature of the coolant at the position adjacent to the second cavity 200b is relatively low, and reduce the influence of high temperature on the cold air in the cold air duct group 300.

[0040] The present application also provides an energy-saving material transportation and heat exchange method, which uses the energy-saving corrugated tube material transportation and heat exchange device described in any one of the above. The material transportation chamber 100 further includes switchable door bodies (not shown in the figure) distributed at both ends in the material transportation direction X. A sealing device can be arranged between the switchable door bodies, for example, sealing strips are arranged on the opposite sides. When the door bodies are closed, the material transportation chamber 100 forms a relatively sealed space, reducing the waste caused by the overflow of the cold air blown out by the cold air duct group 300. The heat exchange method includes: During the material feeding process, the door of the material transportation chamber 100 is closed, the coolant is continuously introduced into the heat exchange chamber 200, and the cold air duct group 300 continuously introduces cold air; during the material transportation process, the door of the material transportation chamber 100 is opened. Taking the production and processing of zircon sand as an example, when the heated zircon sand is transported to the water washing process, first, the heated zircon sand needs to be fed into the material box, and then it is transported to the water washing device through the conveyor belt passing through the material transportation chamber 100. During the feeding process, the conveyor belt does not move. At this time, the door of the material transportation chamber 100 is closed. Cold air is introduced to cool the material a in the material transportation chamber 100. The material a will be cooled multiple times during the entire transportation process in the material transportation chamber 100, and finally, the temperature of the material a coming out from the discharge end of the material transportation chamber 100 is cooled to a suitable temperature before water washing, which can avoid the problem of evaporation of the water washing solution caused by the too high temperature of the material. For the specific feeding and transportation process, the coolant can be continuously introduced into the heat exchange chamber 200. In addition, during the feeding and transportation process, the process of introducing cold air into the heat exchange chamber 200 can also continue without stopping. The door can be set as an opening only for the passage of the material a, and a flexible sealing curtain is provided at the opening to reduce the leakage of cold air. The length of the material transportation chamber 100 can be set according to the time required for the material a to be cooled to a usable temperature in the material transportation chamber 100.

The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this application shall be included within the scope of protection of this application.
