Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat exchanger technology, and in particular to a heat exchange device for high-concentration materials. Background Technology
[0002] In industries such as chemical, food, pharmaceutical, and environmental protection, it is often necessary to heat or cool high-concentration materials. However, high-concentration materials are prone to problems due to their high viscosity, poor flowability, and tendency to scale. Examples of high-concentration materials prone to scaling in the chemical industry include molten polyethylene, polypropylene, and nylon; in the food industry, high-concentration materials include sauces, dairy products, and jams; in the pharmaceutical industry, high-concentration materials include bio-fermentation broths and traditional Chinese medicine extracts; and in the environmental protection industry, high-concentration materials include industrial sludge and municipal sludge. Traditional heat exchangers can easily cause the following problems:
[0003] When high-concentration materials flow through the inside of a heat exchanger, they easily deposit on the inner wall of the pipes, causing blockages, affecting heat exchange efficiency, and even causing equipment shutdown. Some components in high-concentration materials are prone to precipitate and adhere to the inner wall of the heat exchanger at high temperatures, forming a scale layer that reduces heat exchange efficiency and increases energy consumption. Traditional heat exchangers have complex structures, are difficult to clean, and struggle to completely remove scale, affecting the long-term stable operation of the equipment.
[0004] To solve the above problems, there is an urgent need for a heat exchange device for high-concentration materials that can improve the problem of the inconvenience of cleaning existing heat exchange devices. Utility Model Content

[0008] To achieve the above objectives, the main technical solutions adopted by this utility model include:
[0009] A heat exchange device for high-concentration materials, comprising:
[0010] A heat exchange body has a heat exchange cavity inside, and the heat exchange body has a heat exchange medium inlet and a heat exchange medium outlet communicating with the heat exchange cavity;

[0012] A pair of end doors are sealed and openable at both ends of the heat exchange body, and multiple material channels are provided on the upper part of the end doors;
[0013] When both of the pair of end gates are closed, the two ends of each material channel are connected to the openings of the two adjacent pipes, thereby forming an S-shaped continuous high-concentration material flow channel through all the material channels on the pair of end gates.

[0025] (III) Beneficial Effects
[0026] The beneficial effects of this utility model are as follows: The heat exchange device for high-concentration materials provided in this embodiment includes a heat exchange body with a heat exchange chamber inside. Pipes penetrate the heat exchange body, with both ends of the pipes opening onto the end faces of the heat exchange body. Multiple parallel pipes provide a large heat exchange surface area, achieving efficient heat exchange.

[0027] The end doors are openably and sealingly located at both ends of the heat exchanger body. Multiple material channels are provided on the inner wall of the end doors. When the end doors are closed, the material channels bridge and cover the end ports of two adjacent pipes, thus connecting multiple pipes in series to form a continuous material flow path. By connecting multiple independent pipes in series through the material channels on the end doors, a material flow path is formed that allows the material to undergo multiple reversals within the device.

[0036] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0037] This invention addresses the technical problems of clogging and scaling in heat exchangers caused by high-concentration materials, which are difficult to clean. It proposes a heat exchange device for high-concentration materials, effectively solving the clogging problem within the heat exchanger, ensuring normal material flow, and improving production efficiency. It facilitates cleaning of scale buildup on the material side, reducing maintenance costs and minimizing production downtime due to maintenance. Furthermore, it improves the heat transfer efficiency of the heat exchanger, reduces energy consumption, and meets energy conservation and environmental protection requirements.
[0038] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.
[0039] See appendix Figure 1-4 As shown, this utility model embodiment provides a heat exchange device for high-concentration materials, including: a heat exchange body 1, multiple parallel pipes, and a pair of end valves 2. The heat exchange body 1 has a heat exchange chamber inside, and a heat exchange medium inlet 11 and a heat exchange medium outlet 12 communicating with the heat exchange chamber. The pipes pass through the heat exchange body 1, and both ends of the pipes open at the end faces of the heat exchange body 1. The end valves 2 are openably and sealingly disposed at both ends of the heat exchange body 1. Multiple material channels 21 are provided on the inner sidewall of the end valves 2. When the end valves 2 are closed, the material channels 21 bridge and cover the end ports of two adjacent pipes, thereby forming a continuous material flow channel through multiple pipes connected in series via the material channels 21. The multiple parallel pipes provide a large heat exchange surface area, achieving efficient heat exchange. At the same time, the independent pipe design is less prone to clogging compared to narrow and complex plate channels, making it particularly suitable for high-concentration, high-viscosity, or particulate materials, achieving both efficient heat exchange and anti-clogging. Multiple independent pipes are connected in series via the material channel 21 on the end gate 2, forming a material flow channel that allows the material to undergo multiple backflows within the device. This significantly extends the total heat exchange path of the material within a limited space, ensuring sufficient heat exchange time. When cleaning or addressing blockages, the end gate can be easily opened to directly expose all pipe ports, enabling mechanical cleaning, high-pressure water jet flushing, or visual inspection of each pipe. Maintenance convenience far surpasses that of traditional fixed tube sheet or plate heat exchangers, facilitating maintenance and cleaning. Furthermore, the complete physical separation of the material channel (pipes) and the heat exchange medium channel (heat exchange chamber) avoids the risk of cross-contamination, resulting in a clear structure and reliable operation.
[0040] The material channel 21 has a hollow U-shaped structure. The streamlined, curved shape of the material channel 21 effectively reduces material flow resistance and prevents dead zones or blockages from forming within it. Furthermore, the U-shaped structure is simple, robust, and easy to cast or machine, reducing manufacturing costs and process complexity. The material channel 21 and the end gate 2 can be integrally injection molded, or separately fixed to the end gate 2 by welding or other methods.
[0041] The end gate 2 is equipped with a material inlet 22 that connects to the beginning of the material flow channel and a material outlet 23 that connects to the end of the material flow channel. By integrating the material inlet, outlet, and material channel 21 onto the end gate, all material connection interfaces are concentrated on the end gate 2 component. This greatly simplifies the design and installation of the external piping system, reduces the number of fittings, elbows, and potential leakage points, lowers installation costs and complexity, and results in a cleaner, more efficient layout that is easier to clean.
[0042] One side of the end door 2 is hinged to the heat exchange body 1, while the other side is detachably fixed to the heat exchange body 1, allowing the end door to rotate and open like a door without complete disassembly. This facilitates quick opening and closing, improving maintenance efficiency. It also shortens equipment downtime for cleaning, enhances operational convenience and equipment utilization, and greatly facilitates frequent maintenance and inspections.
[0043] The edge of the end door 2 is provided with a flange so that the end door 2 can be sealed and fixed to the heat exchange body 1 by bolts or clamps. Bolted connection provides a robust, reliable, and high-pressure sealing connection method, suitable for harsh conditions such as high pressure and high temperature. Clamp connection provides quick opening and closing capability, further shortening maintenance time, suitable for occasions requiring frequent cleaning, and greatly reducing the labor intensity of operators.
[0044] A sealing gasket is installed between the end valve 2 and the end face of the heat exchange body 1. The sealing gasket includes a sealing gasket surrounding the pipe and a sealing gasket surrounding the edge of the end valve 2. The installation of the sealing gasket is crucial to ensuring a large-area planar seal between the end valve 2 and the end face of the heat exchange body 1. It effectively prevents the heat exchange medium from leaking from the heat exchange chamber, and also prevents materials from leaking out from the pipe port, ensuring the stability and safety of the production process and avoiding material loss and environmental pollution.
[0045] The inner wall of the pipe is polished. Making the inner wall polished significantly reduces roughness, making it difficult for high-viscosity or easily fouling materials to adhere to and accumulate. This not only reduces the decrease in heat exchange efficiency caused by scaling but also makes cleaning easier and more thorough, fundamentally alleviating clogging problems, maintaining stable heat exchange performance, and significantly reducing the risk of adhesion and clogging.
[0046] The pipe diameter is usually DN100 (nominal diameter). By setting up a large-diameter pipe, most high-concentration, particulate slurries can pass through smoothly without clogging. At the same time, the heat exchange efficiency will not be significantly reduced due to the excessive pipe diameter (too large a pipe diameter makes it difficult to form turbulence and easily forms a stagnation zone), thus achieving a perfect balance between smooth flow and high efficiency.
[0047] The heat exchange medium inlet 11 is located at the top of the heat exchange body 1, and the heat exchange medium outlet 12 is located on the side of the heat exchange body 1. The top location of the heat exchange medium inlet facilitates the removal of air from the heat exchange chamber (exhaust), ensuring that the heat exchange medium (especially liquid) fills the entire chamber, preventing the formation of air pockets, and thus ensuring effective utilization of the heat exchange area. The side location of the heat exchange medium outlet, in conjunction with the top inlet, guides the heat exchange medium to flow more uniformly throughout the heat exchange chamber, reducing short-circuit flow and improving the utilization rate of the heat exchange medium, thereby achieving more efficient and uniform heat exchange.
[0048] The opening angle of end valve 2 is 0-270°. This extra-large opening angle allows end valve 2 to open backward without obstructing the heat exchange medium outlet 12, providing operators with an unobstructed and extremely wide field of vision and operating space. Personnel can easily approach, observe, and touch all pipe ports, the sealing surfaces inside end valve 2, and the reflux chamber. Whether performing routine inspections, clearing blockages, replacing seals, or cleaning, it is extremely convenient, eliminating the need for awkward or forced operations. Simultaneously, the open space allows for the use of large, efficient cleaning equipment, such as long-handled high-pressure water guns, mechanical scrubbers, or even automated cleaning devices. Compared to doors that can only open to 90° or less, the operation of large tools is severely limited, resulting in poor cleaning effectiveness. The 270° opening angle completely solves this problem, ensuring that cleaning tools can operate without blind spots, thereby improving cleaning efficiency and quality and guaranteeing the complete restoration of the heat exchanger's performance.
[0049] The heat exchange device for high-concentration materials provided in this embodiment includes a heat exchange body 1 with a heat exchange chamber inside. Pipes penetrate the heat exchange body 1, with both ends of the pipes opening onto the end faces of the heat exchange body 1. Multiple parallel pipes provide a large heat exchange surface area, achieving efficient heat exchange. Furthermore, the independent pipe design is less prone to clogging compared to narrow and complex plate channels, making it particularly suitable for high-concentration, high-viscosity, or particulate materials, achieving a balance between efficient heat exchange and anti-clogging.
[0050] End doors 2 are openably and sealingly installed at both ends of the heat exchange body 1. Multiple material channels 21 are provided on the inner wall of the end doors 2. When the end doors 2 are closed, the material channels 21 bridge and cover the end ports of two adjacent pipes, thus connecting multiple pipes in series to form a continuous material flow channel. By connecting multiple independent pipes in series through the material channels 21 on the end doors 2, a material flow channel is formed that allows the material to undergo multiple reversals within the device. Within a limited space, this greatly extends the total heat exchange path of the material, ensuring sufficient heat exchange time. When cleaning or addressing blockages is required, the end doors can be easily opened to directly expose the ports of all pipes, enabling mechanical cleaning, high-pressure water jet flushing, or visual inspection of each pipe. Maintenance convenience far exceeds that of traditional fixed tube sheet or plate heat exchangers, facilitating maintenance and cleaning.
[0051] The end gate 2 is equipped with a material inlet 22 that connects to the beginning of the material flow channel and a material outlet 23 that connects to the end of the material flow channel. By integrating the material inlet 22, the material outlet 23, and the material channel 21 on the end gate, the number of pipe fittings, elbows, and potential leakage points is reduced, the installation cost and complexity are reduced, the layout is more neat and efficient, it is convenient to clean the scale on the material side, the maintenance cost is reduced, and the production interruption time caused by maintenance is reduced.
