Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, and in particular to a waste heat recovery transportation pipeline. Background Technology

[0002] Waste heat refers to the heat generated in various industrial production processes, energy conversion processes, and daily life activities that is not fully utilized and is released into the environment. For example, brick factories generate a large amount of waste heat during production, which is usually directly released into the atmosphere, resulting in energy waste and potential negative environmental impacts. With the continuous increase in energy demand and growing environmental awareness, how to efficiently utilize waste heat, reduce energy consumption, and mitigate environmental pollution has become an urgent problem to be solved in various industrial sectors.

[0003] Traditional waste heat recovery methods involve transporting waste gas or wastewater through pipelines to specialized heat recovery equipment. This transportation process results in heat waste. Current waste heat recovery pipelines often only have heat exchange pipes within the main pipeline. Heat exchange media are circulated through these pipes to absorb heat from the waste gas or wastewater, resulting in low heat exchange efficiency and poor heat exchange performance. Utility Model Content

[0004] The purpose of this invention is to provide a waste heat recovery and transportation pipeline to solve the problems existing in the prior art. It has a simple structure and improves heat exchange efficiency.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] This utility model provides a waste heat recovery transport pipeline, including at least one pipeline body and at least two guide plates. Each pipeline body is provided with at least one liquid inlet and at least one liquid outlet. At least two guide plates are provided inside each pipeline body, and a gap is left between each guide plate and the inner wall of the corresponding pipeline body. The gap is a transport channel for fluid to pass through, and two adjacent transport channels are staggered. Each guide plate is provided with a first heat exchange channel for the flow of heat exchange medium. The liquid inlet and liquid outlet of each first heat exchange channel are respectively connected to the liquid inlet and liquid outlet of the corresponding pipeline body.

[0007] Preferably, each of the pipe bodies has a second heat exchange channel in the two side walls that are opposite to each other, and the liquid inlet and liquid outlet of each of the first heat exchange channels are respectively connected to the two second heat exchange channels of the corresponding pipe body.

[0008] Preferably, each of the pipe bodies has a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall connected in sequence. A second heat exchange channel is provided in each of the first sidewalls and each of the third sidewalls. Two adjacent guide plates of each pipe body are fixedly connected to the corresponding second sidewall and the corresponding fourth sidewall. A gap is left between each guide plate connected to each of the second sidewalls and the inner wall of the corresponding fourth sidewall to form the transport channel. A gap is left between each guide plate connected to each of the fourth sidewalls and the inner wall of the corresponding second sidewall to form the transport channel.

[0009] Preferably, each of the guide vanes is inclined, and the end of each guide vane near the transport channel extends toward the outlet direction of the corresponding pipe body.

[0010] Preferably, it further includes at least one heat exchange tube for the flow of the heat exchange medium, and each of the pipe bodies is provided with at least one heat exchange tube, and the liquid inlet and liquid outlet of each heat exchange tube are respectively connected to the liquid inlet and liquid outlet of the corresponding pipe body.

[0011] Preferably, the liquid inlet and liquid outlet of each heat exchange tube are respectively connected to the two second heat exchange channels of the corresponding pipe body.

[0014] Preferably, each of the supports is provided with a plurality of heat exchange tubes, and the distance between the plurality of heat exchange tubes on each of the supports and the fourth sidewall is different.

[0015] Preferably, an insulation layer is provided on the outer side of each of the pipe bodies.

[0016] The present invention achieves the following technical advantages over the prior art:

[0017] This utility model provides a waste heat recovery transport pipeline. Each pipeline body is provided with at least one liquid inlet and at least one liquid outlet. At least two guide plates are provided inside each pipeline body. A gap is left between each guide plate and the inner wall of the corresponding pipeline body. The gap is a transport channel for fluid to pass through. Two adjacent transport channels are staggered. Each guide plate is provided with a first heat exchange channel for the flow of heat exchange medium. The liquid inlet and liquid outlet of each first heat exchange channel are respectively connected to the liquid inlet and liquid outlet of the corresponding pipeline body.

[0018] Waste gas or waste liquid enters through the inlet of the pipeline body and is transported sequentially through multiple transport channels towards the outlet of the pipeline body. Because adjacent transport channels are staggered, the transport direction of the fluid is altered, causing it to flow in a zigzag pattern instead of along the length of the pipeline body. This increases the actual flow path length within the pipeline body, thereby extending the residence time of the fluid and improving heat exchange efficiency. Simultaneously, the guide plate of this invention incorporates a first heat exchange channel. The heat exchange medium is added through the inlet of the pipeline body and flows out through the outlet after passing through each of the first heat exchange channels. During its flow within the first heat exchange channels, the heat exchange medium exchanges heat with the fluid within the pipeline body, thus achieving waste heat recovery from the fluid within the pipeline body. The guide plate of this invention serves both as a guide and a flow channel for the heat exchange medium, simplifying the structure while ensuring effective heat exchange.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The purpose of this invention is to provide a waste heat recovery and transportation pipeline to solve the problems existing in the prior art. It has a simple structure and improves heat exchange efficiency.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1-3 As shown, this utility model provides a waste heat recovery transport pipeline 100, including at least one pipeline body 1 and at least two guide plates 2. Each pipeline body 1 is provided with at least one liquid inlet 101 and at least one liquid outlet 102. At least two guide plates 2 are provided inside each pipeline body 1, and a gap is left between each guide plate 2 and the inner wall of the corresponding pipeline body 1. The gap is a transport channel 3 for fluid to pass through, and two adjacent transport channels 3 are staggered. Each guide plate 2 is provided with a first heat exchange channel 201 for the flow of heat exchange medium. The liquid inlet and liquid outlet of each first heat exchange channel 201 are respectively connected to the liquid inlet 101 and liquid outlet 102 of the corresponding pipeline body 1.

[0028] Waste gas or waste liquid enters through the inlet of the pipe body 1 and is transported sequentially through multiple transport channels 3 towards the outlet of the pipe body 1. Because adjacent transport channels 3 are staggered, the transport direction of the fluid is changed, so that the fluid is no longer transported along the length of the pipe body 1, but in a zigzag pattern. This increases the actual flow path length of the fluid within the pipe body 1, thereby extending the residence time of the fluid in the pipe body 1 and improving the heat exchange effect. Simultaneously, the guide plate 2 of this invention is provided with a first heat exchange channel 201. The heat exchange medium is added through the liquid inlet 101 of the pipe body 1. The heat exchange medium can flow out through the liquid outlet 102 after passing through each of the first heat exchange channels 201. During the flow of the heat exchange medium within the first heat exchange channels 201, it can exchange heat with the fluid within the pipe body 1, thereby realizing the recovery of waste heat from the fluid within the pipe body 1. The guide plate 2 of this invention can both guide the flow and serve as a flow channel for the heat exchange medium, simplifying the structure while ensuring the heat exchange effect.

[0029] In this invention, each pipe body 1 has two oppositely arranged side walls with a second heat exchange channel 103. The liquid inlet and liquid outlet of each first heat exchange channel 201 are respectively connected to the two second heat exchange channels 103 of the corresponding pipe body 1. After the heat exchange medium enters through the liquid inlet 101, it passes through one second heat exchange channel 103, multiple first heat exchange channels 201, and another second heat exchange channel 103 of each pipe body 1 in sequence, and is discharged through the corresponding liquid outlet 102. During this process, the heat exchange medium in the first heat exchange channel 201 and the second heat exchange channel 103 can exchange heat with the fluid in the pipe body 1, which is beneficial to improving the heat exchange efficiency.

[0030] In this invention, each pipe body 1 has a first sidewall 104, a second sidewall 105, a third sidewall 106, and a fourth sidewall 107 connected in sequence. A second heat exchange channel 103 is provided within each first sidewall 104 and each third sidewall 106. Two adjacent guide plates 2 of each pipe body 1 are fixedly connected to the corresponding second sidewall 105 and fourth sidewall 107, respectively. A gap is left between each guide plate 2 connected to the second sidewall 105 and the inner wall of the corresponding fourth sidewall 107 to form a transport channel 3. A gap is also left between each guide plate 2 connected to the fourth sidewall 107 and the inner wall of the corresponding second sidewall 105 to form a transport channel 3. The ends of two adjacent guide plates 2 are respectively separated from two opposing sidewalls (second sidewall 105 and fourth sidewall 107), allowing the fluid entering the pipe body 1 to flow in a zigzag pattern along the length of the pipe body 1, thereby extending the residence time of the fluid in the pipe body 1.

[0031] In this invention, each guide plate 2 is inclined, and the end of each guide plate 2 closest to the transport channel 3 extends toward the outlet direction of the corresponding pipe body 1. Because each guide plate 2 is inclined toward the outlet direction of the pipe body 1, the probability of backflow of waste heat fluid can be reduced, allowing the fluid to flow in one direction as much as possible, thereby ensuring the stability of the system.

[0032] This invention also includes at least one heat exchange tube 4 for supplying the heat exchange medium. Each pipe body 1 contains at least one heat exchange tube 4, and the liquid inlet and liquid outlet of each heat exchange tube 4 are respectively connected to the liquid inlet 101 and liquid outlet 102 of the corresponding pipe body 1. The heat exchange medium can enter each heat exchange tube 4 through the liquid inlet 101 and exit through the liquid outlet 102. When the fluid flows within the pipe body 1, it flows over the outer wall of the heat exchange tube 4, thereby allowing the heat exchange medium to exchange heat with the fluid. The first heat exchange channel 201, the second heat exchange channel 103, and the heat exchange tube 4 of this invention can all supply the heat exchange medium for flow and heat exchange, greatly improving the heat exchange effect.

[0033] In this invention, the liquid inlet and liquid outlet of each heat exchange tube 4 are respectively connected to two second heat exchange channels 103 of the corresponding pipe body 1. After the heat exchange medium enters through the liquid inlet 101, it passes sequentially through one second heat exchange channel 103 of each pipe body 1, the heat exchange tube 4, and the other second heat exchange channel 103 of the corresponding pipe body 1, and is discharged through the corresponding liquid outlet 102. During this process, the heat exchange medium in the heat exchange tube 4 can exchange heat with the fluid in the pipe body 1.

[0034] This invention also includes at least one support 5, each support 5 being fixedly connected inside a pipe body 1, and each heat exchange tube 4 being fixedly connected to at least one support 5. The support 5 can support the heat exchange tube 4, preventing the heat exchange tube 4 from shaking due to fluid flow inside the pipe body 1, thus contributing to the stability of the heat exchange tube 4 installation.

[0035] In this invention, each heat exchange tube 4 is detachably and fixedly connected to at least one bracket 5, preferably by snap-fit, which is simple in structure and easy to assemble and disassemble.

[0036] In this invention, each support 5 is provided with multiple heat exchange tubes 4, which can further improve the heat exchange effect. The distance between the multiple heat exchange tubes 4 on each support 5 and the fourth side wall 107 is different. When the fluid flows through the pipe body 1, it can better contact the outer wall of the heat exchange tubes 4, thus ensuring the heat exchange effect.

[0037] In this invention, an insulation layer 6 is provided on the outside of each pipe body 1, which can reduce heat loss of fluid during transportation within the pipe body 1 and improve energy recovery rate.

[0038] In this invention, each pipe body 1 is provided with multiple guide plates 2 and multiple supports 5. The number of guide plates 2, heat exchange tubes 4, and supports 5 can be adjusted according to the length of the pipe body 1. The heat exchange medium includes, but is not limited to, water. In a preferred embodiment, each heat exchange tube 4 is connected to a support 5, the support 5 is located in the middle of the heat exchange tube 4, the support 5 is inclined, and multiple heat exchange tubes 4 are arranged along the length of the support 5 to ensure that more heat exchange tubes 4 can be installed on the same support 5. The inclination direction of the support 5 is preferably the same as that of the guide plate 2. The heat exchange tubes 4 are both hot and cold tubes.

[0039] In this invention, each pipe body 1 has a mounting frame 7 protruding from its outer edges at both ends. The mounting frame 7 has several mounting holes 701 drilled at equal intervals, allowing the pipe body 1 to be stably installed at the desired location. The number of pipe bodies 1 can be set according to usage requirements. Multiple pipe bodies 1 can be installed at the desired locations of multiple external components, or multiple pipe bodies 1 can be sealed together to form a pipe of a specific length.

[0040] In this invention, the inlet 101 and the outlet 102 can be located on two opposite side walls, or they can be located on one side wall. When the inlet 101 and the outlet 102 are located on the same side wall, such as on the first side wall 104, the inlet 101 can be connected to the second heat exchange channel 103 through a connecting pipe. This allows the heat exchange medium to first enter the second heat exchange channel 103 on the third side wall 106 through the connecting pipe, and then flow back to the second heat exchange channel 103 on the first side wall 104 through the first heat exchange channel 201 and the heat exchange tube 4, and be discharged through the outlet 102, thus achieving circulation.

[0041] The working principle of the waste heat recovery and transportation pipeline 100 of this utility model is as follows:

[0042] The pipe body 1 is fixed to the exhaust outlet using bolts and mounting holes 701, and the matching pipes are installed on the inlet 101 and outlet 102. When hot exhaust gas enters the pipe body 1, the gas flows through the heat exchange pipe 4 and the guide plate 2, exchanging heat with the heat exchange medium flowing inside the heat exchange pipe 4, the first heat exchange channel 201, and the second heat exchange channel 103. The guide plate 2 can change the flow direction of the exhaust gas, prolong the residence time of the exhaust gas in the pipe body 1, effectively cool the exhaust gas, and absorb the waste heat of the exhaust gas. The heat exchange medium after heat exchange flows out from the outlet 102 and is collected for waste heat utilization. By using the heat exchange pipe 4, the first heat exchange channel 201, and the second heat exchange channel 103 to recover waste heat from the exhaust gas, the heat exchange efficiency can be improved, and the heat exchange medium in the second heat exchange channel 103 can achieve a certain heat preservation effect after absorbing heat.

The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
