Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat exchanger technology, and in particular to a high-efficiency heat exchanger for petrochemical applications. Background Technology
[0002] In the petrochemical production process, various chemical reactions and processes require precise temperature control to ensure product quality and production efficiency. As a device that can efficiently transfer heat energy between two fluids, heat exchangers are of great significance for improving the energy efficiency of petrochemical processes and reducing energy consumption.
[0003] As disclosed in the prior art, patent CN222012791U discloses a high-efficiency heat exchanger for petrochemicals. This utility model uses a spiral heat exchange tube design, which allows cold water to fully contact hot water during the flow process, extending the heat exchange path and thus improving the heat exchange efficiency. The hot water flows up and down between the two baffles, further increasing the flow time and allowing the heat to be transferred more fully. The heat exchange tanks one and two have the same structure, which gives this heat exchanger the advantage of modular design. This design makes the equipment easy to maintain and expand. The number of heat exchange tanks can be increased or decreased according to actual needs to flexibly meet different heat exchange requirements.
[0004] However, the cold water in this device can only exchange heat through the transfer of hot water to the heat exchange tubes. The limited contact area between the hot water and the heat exchange tubes affects the heat exchange effect. Therefore, a high-efficiency heat exchanger for petrochemical applications is designed to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a high-efficiency heat exchanger for petrochemical industry.
[0006] The technical problem to be solved by this utility model is to provide a high-efficiency heat exchanger for petrochemical industry, which solves the problem in the prior art that the end of the motor connection wire cannot be fixed when the device is winding up, thus affecting the winding efficiency.
[0007] This utility model provides a high-efficiency heat exchanger for petrochemical applications, comprising a heat exchange tank, support plates, support seats, a cold water inlet pipe, a hot water inlet pipe, a first partition, and a second partition. Support plates are fixedly installed on both the left and right sides of the bottom surface of the heat exchange tank, and support seats are fixedly installed at the bottom of both support plates. A cold water inlet pipe and a hot water inlet pipe are threaded through the left end of the upper surface of the heat exchange tank. A first partition is fixedly installed on the left side of the interior of the heat exchange tank, and a second partition is fixedly installed on the right side of the interior of the heat exchange tank. Multiple spring-shaped heat exchange tubes are threaded through between the first and second partitions, and multiple heat-conducting rods are fixedly installed on the inner surface of the spring-shaped heat exchange tubes. A cold water discharge valve and a hot water discharge valve are threaded through the left end of the bottom of the heat exchange tank.
[0008] Preferably, both the spring-shaped heat exchange tube and the heat-conducting rod are made of copper, a material with good thermal conductivity.
[0009] Preferably, the heat-conducting rods are evenly distributed on the inner surface of the spring-shaped heat exchange tube.
[0010] Preferably, the cold water inlet pipe is located on the left side of the first partition, the hot water inlet pipe is located on the right side of the first partition, the cold water outlet valve is located on the right side of the second partition, and the hot water outlet valve is located on the left side of the second partition.
[0011] Preferably, the heat exchange tank includes a left half, a right half, an external threaded cylinder, and an internal threaded sleeve. The heat exchange tank is divided into a left half and a right half. An external threaded cylinder is fixedly installed at the right end of the left half, and an internal threaded sleeve is fixedly installed on the left side of the right half. The internal threaded sleeve is threadedly connected to the external threaded cylinder.
[0012] Preferably, the length of the external threaded cylinder and the internal threaded sleeve is 1 / 3 of the length of the heat exchange tank.
[0013] Preferably, the spring-shaped heat exchange tube is elastic and can extend and retract.
[0014] Compared with the prior art, this utility model has at least the following beneficial effects:
[0015] 1. This utility model, by setting up a spring-shaped heat exchange tube and a heat-conducting rod, allows cold water to enter the left side of the heat exchange tank through the cold water inlet pipe, then enter the spring-shaped heat exchange tube, and then enter the right side of the second partition. Hot water enters the space between the first and second partitions inside the heat exchange tank through the hot water inlet pipe, where it comes into contact with the spring-shaped heat exchange tube, thus achieving the heat exchange effect. The spring-shaped heat exchange tube increases the flow time of the cold water in the pipe, thereby increasing the heat exchange effect. Furthermore, the heat-conducting rod increases the contact area between the cold water and the spring-shaped heat exchange tube, further enhancing the heat exchange effect.
[0016] 2. This utility model divides the heat exchange tank into a left half and a right half, and connects the internal thread of the right half to the external threaded cylinder on the left half. This allows the overall length of the heat exchange tank to be adjusted according to the amount of internal thread connecting to the external threaded cylinder, thereby increasing or decreasing the distance and time of hot water flow in the heat exchange tank. The heat exchange path of the heat exchanger can be adjusted according to needs, increasing its practicality. Attached Figure Description

Detailed Implementation
[0025] Example:
[0026] like Figures 1-5As shown, an embodiment of this utility model provides a high-efficiency heat exchanger for petrochemical applications, including a heat exchange tank 1, a support plate 2, a support base 3, a cold water inlet pipe 4, a hot water inlet pipe 5, a first partition 6, and a second partition 7. Support plates 2 are fixedly installed on both the left and right sides of the bottom surface of the heat exchange tank 1, and support bases 3 are fixedly installed at the bottom of both support plates 2. A cold water inlet pipe 4 and a hot water inlet pipe 5 are passed through the left end of the upper surface of the heat exchange tank 1. A first partition 6 is fixedly installed on the left side of the interior of the heat exchange tank 1, and a second partition 7 is fixedly installed on the right side of the interior of the heat exchange tank 1. Multiple spring-shaped heat exchange tubes 8 are passed through between the first partition 6 and the second partition 7. Multiple heat-conducting rods 801 are fixedly installed on the inner surface of the spring-shaped heat exchange tubes 8. A cold water discharge valve 9 and a hot water discharge valve 10 are passed through the left end of the bottom of the heat exchange tank 1.
[0027] In this embodiment, both the spring-shaped heat exchange tube 8 and the heat-conducting rod 801 are made of copper material with good thermal conductivity, ensuring the thermal conductivity of the spring-shaped heat exchange tube 8 and the heat-conducting rod 801.
[0028] In this embodiment, the heat-conducting rods 801 are evenly distributed on the inner surface of the spring-shaped heat exchange tube 8 to ensure the uniformity of heat transfer.
[0029] In this embodiment, the cold water inlet pipe 4 is located on the left side of the first partition 6, the hot water inlet pipe 5 is located on the right side of the first partition 6, the cold water outlet valve 9 is located on the right side of the second partition 7, and the hot water outlet valve 10 is located on the left side of the second partition 7, ensuring the normal entry and exit of hot and cold water.
[0030] By incorporating a spring-shaped heat exchange tube 8 and a heat-conducting rod 801, during the heat exchange process, cold water enters the left side of the heat exchange tank 1 through the cold water inlet pipe 4, then enters the spring-shaped heat exchange tube 8, and finally enters the right side of the second partition 7. Hot water enters the space between the first partition 6 and the second partition 7 inside the heat exchange tank 1 through the hot water inlet pipe 5. The hot water comes into contact with the spring-shaped heat exchange tube 8, achieving the heat exchange effect. The spring-shaped heat exchange tube 8 increases the flow time of cold water in the pipe, thereby increasing the heat exchange effect. Furthermore, the heat-conducting rod 801 increases the contact area between the cold water and the spring-shaped heat exchange tube 8, further enhancing the heat exchange effect.
[0031] In this embodiment, the heat exchange tank 1 includes a left half 101, a right half 102, an external threaded cylinder 103, and an internal threaded sleeve 104. The heat exchange tank 1 is divided into a left half 101 and a right half 102. An external threaded cylinder 103 is fixedly provided at the right end of the left half 101, and an internal threaded sleeve 104 is fixedly provided at the left side of the right half 102. The internal threaded sleeve 104 is threadedly connected to the external threaded cylinder 103.
[0032] In this embodiment, the lengths of the external threaded cylinder 103 and the internal threaded sleeve 104 are 1 / 3 of the length of the heat exchange tank 1.
[0033] In this embodiment, the spring-shaped heat exchange tube 8 is elastic and can be extended and retracted, and the spring-shaped heat exchange tube 8 will not affect the adjustment of the length of the heat exchange tank 1.
[0034] By dividing the heat exchange tank 1 into a left half 101 and a right half 102, and connecting the inner threaded sleeve 104 of the right half to the outer threaded cylinder 103 on the left half 101, the overall length of the heat exchange tank 1 can be adjusted according to the amount of the inner threaded sleeve 104 connected to the outer threaded cylinder 103. This increases the distance and time that hot water flows in the heat exchange tank 1, and the heat exchange path of the heat exchanger can be adjusted according to needs, thus increasing its practicality.
[0035] When the internal threaded sleeve 104 is threadedly connected to the external threaded cylinder 103, the sealing of the connection between the internal threaded sleeve 104 and the external threaded cylinder 103 can be ensured by wrapping pipe tape around the external threaded cylinder 103 to prevent water leakage. After the internal threaded sleeve 104 is threadedly connected to the external threaded cylinder 103, the two support seats 3 must be facing directly downwards.
[0036] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
