Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to a heat exchanger specifically designed for low-temperature heating. Background Technology

[0002] In some industrial production processes, high-temperature steam or gases are generated. These gases are generally difficult to use in production due to impurities and are usually treated before being released into the environment. Because they are generated at high temperatures, treating them before release leads to a significant loss of heat, resulting in underutilization and reducing the overall energy efficiency of industrial production.

[0003] An existing low-temperature flue gas waste heat recovery heating system uses a heat pipe heat exchanger to recover waste heat from low-temperature flue gas to produce hot water for heating, thus replacing the original heating system and achieving energy saving and emission reduction. However, because the gas temperature is high, the water temperature after heat exchange is also high, and high water temperatures in the heating system can cause discomfort. Therefore, this invention proposes a dedicated low-temperature heating heat exchanger. Utility Model Content

[0004] The purpose of this invention is to address the problem in the prior art where the high temperature of the gas leads to a high water temperature after heat exchange, which can cause discomfort in the heating system. This invention proposes a heat exchanger specifically for low-temperature heating.

[0005] The technical solution of this utility model is as follows: A heat exchanger for low-temperature heating includes a hollow housing, an air inlet pipe at one end of the housing, and an air outlet pipe at the end of the housing away from the air inlet pipe, both of which are connected to the housing; a partition installed in the housing, which divides the housing into heating and exhaust channels; a circulation mechanism installed on the housing, which circulates water; and a gas volume regulating component installed in the housing near the end of the air inlet pipe, which regulates the amount of gas entering the heating and exhaust channels.

[0006] Optionally, the circulation mechanism includes a water pump installed on the outside of the housing, with an inlet pipe connected to the input end of the water pump and multiple sets of heating capillaries connected to the output end of the water pump, all of which are arranged in the heating flow channel.

[0007] Optionally, the ends of the multiple sets of heating capillary tubes away from the water pump all penetrate the housing and are fixedly connected to a central box. The central box is hollow and communicates with the multiple sets of heating capillary tubes. A drain pipe is also connected to the side of the central box away from the heating capillary tubes, and the drain pipe is also communicated with the central box.

[0008] Optionally, the air volume regulating component includes a base plate fixedly installed in the housing via a fixing plate. The top of the base plate is rotatably connected to multiple sets of first rotating rods. Each set of first rotating rods is fixedly connected to a set of guide plates at its top. The multiple sets of guide plates are arranged in an equidistant array. A second rotating rod is also fixedly connected to the side of the multiple sets of guide plates away from the first rotating rods.

[0009] Optionally, a fixing box is provided on the side of the guide plate away from the bottom plate. The fixing box is also fixedly installed on the inner wall of the box by a fixing plate. The fixing box is hollow. The ends of multiple sets of second rotating rods away from the guide plate all pass through the fixing box and are fixedly connected to gears. The sides of the gears are provided with racks. Multiple sets of gears mesh with the racks. A push rod motor is also installed on the outside of the box.

[0012] Optionally, the partition is provided with heat insulation cotton.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] This invention utilizes a circulation mechanism to deliver water to a heating capillary tube for heating, while simultaneously circulating the water to achieve circulating heating and effectively utilize the heat in the high-temperature gas.

[0015] Furthermore, by setting the gas volume adjustment component, the flow direction of the gas can be adjusted, thereby adjusting the amount of high-temperature gas passing through the heating channel and the exhaust channel. When the water temperature is too high, the amount of gas in the heating channel is reduced, and when the water temperature is too low, the amount of gas in the heating channel is increased, so that the hot water supply temperature is suitable.

[0016] In summary, this invention can reuse the heat in high-temperature gas and regulate the temperature of the heating water to ensure that the heating system provides a suitable temperature. Attached Figure Description

[0032] Example

[0033] like Figure 1-3 As shown, this utility model proposes a special heat exchanger for low-temperature heating, comprising a hollow housing 1. An inlet pipe 11 is installed at one end of the housing 1, and an outlet pipe 12 is installed at the end of the housing 1 away from the inlet pipe 11. Both the inlet pipe 11 and the outlet pipe 12 are connected to the housing 1, facilitating the entry of high-temperature gas into the housing 1 through the inlet pipe 11 and its exit from the housing 1 through the outlet pipe 12. Simultaneously, the discharged gas is purified before being released into the atmosphere, avoiding environmental pollution.

[0034] Furthermore, the heat exchanger includes a partition 2 installed in the housing 1. The partition 2 divides the housing 1 into two channels: a heating channel and an exhaust channel. This allows some gas to heat the water while some gas is directly discharged, facilitating the reduction of the water's temperature after heating. Insulation cotton 21 is installed in the partition 2 to effectively prevent heat from the exhaust channel from entering the heating channel, thus facilitating the control of the water temperature in the heating channel. A mesh plate 5 is installed on one side of the partition 2, positioned within the heating channel. The multiple holes in the mesh plate 5 disperse the gas as it passes through, ensuring uniform and effective contact between the high-temperature gas and the heating capillary tube 33, thereby improving the heat exchange effect.

[0035] Furthermore, the heat exchanger also includes a circulation mechanism 3 installed on the housing 1, which circulates the water. The circulation mechanism 3 includes a water pump 31 installed on the outside of the housing 1. The input end of the water pump 31 is connected to an inlet pipe 32, and the output end of the water pump 31 is connected to multiple sets of heating capillaries 33. The water pump 31 draws water from the inlet pipe 32 and discharges it into the heating capillaries 33. All sets of heating capillaries 33 are arranged in heating channels. High-temperature gas heats the water within the heating capillaries 33 after contacting them, thus increasing the water temperature. The ends of multiple heating capillary tubes 33 away from the water pump 31 all pass through the housing 1 and are fixedly connected to a central box 34. The central box 34 is hollow and connected to the multiple heating capillary tubes 33. A drain pipe 35 is also connected to the side of the central box 34 away from the heating capillary tubes 33. The drain pipe 35 is also connected to the central box 34, so that the water in the multiple heating capillary tubes 33 can be collected into a drain pipe 35.

[0036] Meanwhile, a thermometer is installed at the end of the drain pipe 35 furthest from the collection box 34 to detect the output water temperature in the tank 1, facilitating temperature adjustment. Due to varying ambient temperatures, the water temperature entering the heating capillary tube 33 via the water pump 31 differs, requiring adjustment to ensure a suitable output temperature. The drain pipe 35 is connected to the user's water network via the inlet pipe 32. Hot water output from the drain pipe 35 passes through the user network, where its temperature decreases, and it flows back through the inlet pipe 32.

[0037] Finally, please see Figure 4 The heat exchanger also includes a gas flow regulating component 4 located at the end of the inlet pipe 11 near the outlet pipe 12. The gas flow regulating component 4 is installed in the housing 1 and is used to regulate the amount of gas entering the heating channel and the exhaust channel. The gas flow regulating component 4 includes a base plate 41 fixedly installed in the housing 1 via a fixing plate. Five sets of first rotating rods 42 are rotatably connected to the top of the fixed base plate 41. A set of guide plates 43 are fixedly connected to the top of each of the five sets of first rotating rods 42, and the guide plates 43 rotate in their original positions. The five sets of guide plates 43 are arranged in an equidistant array and are parallel to each other. A second rotating rod is also fixedly connected to the side of the five sets of guide plates 43 away from the first rotating rods 42. A fixing box 44 is provided on the side of the guide plates 43 away from the base plate 41. The fixing box 44 is also fixedly installed on the inner wall of the housing 1 via a fixing plate, and its position is fixed. The fixed box 44 is hollow. The ends of the five sets of second rotating rods furthest from the guide plate 43 all pass through the fixed box 44 and are fixedly connected to gears 45. When the gears 45 rotate, the second rotating rods rotate, and simultaneously the guide plate 43 and the first rotating rod 42 rotate synchronously. A rack 46 is provided on the side of the gears 45, and all five sets of gears 45 mesh with the rack 46. When the rack 46 moves, it drives the five sets of gears 45 to rotate synchronously. A push rod motor 49 is also installed on the outside of the housing 1. The output end of the push rod motor 49 passes through the housing 1 and the air volume regulating component 4 in sequence and is fixedly connected to the rack 46. After starting, the push rod motor 49 drives the rack 46 to move. Moving bars 47 are fixedly connected to both sides of the rack 46, and the moving bars 47 move synchronously with the rack 46. Limiting strips 48 are provided on both sides of the moving strip 47. The moving strip 47 is slidably connected between the two sets of limiting strips 48. All four sets of limiting strips 48 are fixedly connected to the inner wall of the fixed box 44. When the rack 46 moves, it is limited by the moving strip 47 and the limiting strips 48, so that the movement of the rack 46 is smooth.

[0038] In this embodiment, firstly, the water pump 31 starts to circulate the water, and high-temperature gas is introduced into the air inlet pipe 11. After passing through the housing 1, the high-temperature gas is discharged through the air outlet pipe 12. When the high-temperature gas passes through the mesh plate 5, it is evenly dispersed, ensuring sufficient contact between the high-temperature gas and the heating capillary tube 33, thus guaranteeing uniform heating of the water in the heating capillary tube 33. When the thermometer senses that the discharged water temperature is too low, the push rod motor 49 is activated to extend. The push rod motor 49 drives the rack 46 to move smoothly under the limiting action of the moving bar 47 and the limiting bar 48. At the same time, the rack 46 meshes with the five sets of gears 45, causing the five sets of gears 45 to rotate synchronously. This causes the five sets of guide plates 43 to deflect, allowing more of the high-temperature gas entering the housing 1 through the air inlet pipe 11 to enter the heating channel and contact the heating capillary tube 33, reducing the amount of gas passing through the exhaust channel, thereby increasing the water temperature. When the water temperature is too high, the push rod motor 49 is activated and shortened, causing multiple sets of guide plates 43 to deflect in opposite directions. This allows more gas to enter the exhaust channel and less gas to enter the heating channel, thereby lowering the discharged water temperature. This ensures that the water is heated at a relatively suitable temperature, guaranteeing comfort.

[0039] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
