Description

Technical Field

[0001] This utility model relates to the field of flue gas waste heat recovery, and in particular to a flue gas waste heat utilization structure with temperature control. Background Technology

[0002] Flue gas waste heat recovery structures are mainly used to recover the heat contained in flue gas and convert it into useful thermal energy. They are one of the commonly used devices that help reduce the energy consumption of boilers and other equipment and save energy.

[0003] Existing flue gas waste heat recovery structures have certain drawbacks. First, while existing structures allow for temperature regulation and control to prevent excessively high or low temperatures from affecting heat exchange efficiency, the temperature control and recovery structures are mostly fixed installations. This makes disassembling the waste heat recovery structure inconvenient when these structures are damaged or require maintenance, thus reducing its practicality. Therefore, we propose a flue gas waste heat recovery structure with temperature control. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a flue waste heat utilization structure with temperature control. By setting a locking block and positioning rods, when the waste heat utilization device needs maintenance or cleaning, pulling a pair of positioning rods causes the positioning rods to move in conjunction with the elastic ring, allowing the positioning rods to drive the locking head to move and separate from the locking block, thus enabling convenient disassembly of the connecting cover. This allows the waste heat utilization device to be easily disassembled and maintained, and is also relatively convenient to install, improving the convenience of maintenance of the temperature control structure and internal structure of the flue waste heat utilization structure, and enhancing the practicality of the flue waste heat utilization structure.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A flue waste heat utilization structure with temperature control includes a flue pipe body, a waste heat utilization device is fixedly connected to the outer end of the flue pipe body, and a maintenance mechanism is movably connected to the outer end of the waste heat utilization device.

[0007] The maintenance mechanism includes a connecting cover, which is movably connected to the outer end of the waste heat utilization device. A controller is fixedly connected to the outer end of the connecting cover, and symmetrically distributed locking blocks are fixedly connected to the inner end of the connecting cover. A positioning rod is slidably connected to the outer end of the locking blocks, and the positioning rod is slidably connected to the inner end of the waste heat utilization device. A locking head is fixedly connected to the front end of the positioning rod.

[0008] The practicality of this flue waste heat utilization structure can be improved by installing locking blocks and positioning rods.

[0009] Furthermore, an elastic ring is fitted onto the outer end of the positioning rod, and a guide ring is movably connected to the outer side of the elastic ring.

[0010] By installing an elastic ring, the positioning rod can drive the chuck to perform positioning and disassembly operations more conveniently.

[0011] Furthermore, the guide ring is located at the outer end of the positioning rod, the inner end of the waste heat utilization device is provided with an adjustment groove, and the inner end of the locking block is provided with a locking groove.

[0012] By installing guide rings and adjustment grooves, the adjustment effect between the structures of the device can be improved.

[0013] Furthermore, the waste heat utilization device has multiple symmetrically distributed assembly racks fixedly connected inside, and each assembly rack has an assembly groove at its inner end.

[0014] By installing assembly racks and assembly slots, the ease of maintenance between the equipment structures can be further improved.

[0015] Furthermore, a box is fixedly connected to the rear end of the flue pipe body, a heat exchange tube is connected to the inner end of the box, a control valve is fixedly connected to the outer end of the heat exchange tube, and a water storage tank is movably connected to the outer end of the heat exchange tube.

[0016] By installing heat exchange tubes, waste heat can be recovered.

[0017] Furthermore, a connecting pipe is fixedly connected to the bottom of the water storage tank, a temperature sensor is installed inside the water storage tank, a vent pipe is fixedly connected to the top of the tank, and a control valve is fixedly connected to the outer end of the vent pipe.

[0018] The efficiency of this flue waste heat utilization structure can be improved by installing temperature sensors and ventilation pipes.

[0019] Furthermore, a connecting plate is fixedly connected to the inner end of the box, and a mounting frame is fixedly connected to the outer end of the box.

[0020] By setting up an installation frame, the waste heat recovery device can be easily connected to the connecting cover, making the disassembly and installation of the connecting cover more convenient.

[0021] Furthermore, multiple filter plates are movably connected inside the housing.

[0022] By installing a filter plate, the structure can perform waste heat recovery, reducing clogging.

[0023] In summary, this utility model has the following beneficial effects:

[0024] 1. By setting up a locking block and positioning rods, when the waste heat utilization device needs maintenance or cleaning, pulling a pair of positioning rods will cause the positioning rods to move in conjunction with the elastic ring, allowing the positioning rods to move the locking head and separate it from the locking block. This allows the connecting cover to be easily disassembled, making the waste heat utilization device easy to disassemble and maintain. It is also relatively easy to install, improving the convenience of maintaining the temperature control structure and internal structure of the flue waste heat utilization structure, and enhancing the practicality of the flue waste heat utilization structure.

[0025] 2. By setting an elastic ring, the elastic ring can move together with the adjustment of the positioning rod. When the positioning rod loses external force, the elastic ring can drive the positioning rod to reset, which makes it more convenient for the positioning rod to drive the chuck to perform positioning and disassembly work.

[0026] 3. By setting up assembly racks and assembly slots, the inner ends of a pair of U-shaped assembly racks are engaged with filter plates. When the filter plates need to be disassembled for maintenance, they can be pulled out from the inner end of the assembly slot, which allows for convenient maintenance of the filter plates and further improves the ease of maintenance between the equipment structures.

Detailed Implementation

[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0035] Reference Figure 1-5 As shown, a flue waste heat utilization structure with temperature control is provided in a preferred embodiment of the present invention. It includes a flue pipe body 1, a waste heat utilization device 2 fixedly connected to the outer end of the flue pipe body 1, and a maintenance mechanism 3 movably connected to the outer end of the waste heat utilization device 2.

[0036] The maintenance mechanism 3 includes a connecting cover 301, which is movably connected to the outer end of the waste heat utilization device 2. A controller 302 is fixedly connected to the outer end of the connecting cover 301. A symmetrically distributed locking block 303 is fixedly connected to the inner end of the connecting cover 301. A positioning rod 304 is slidably connected to the outer end of the locking block 303. The positioning rod 304 is slidably connected to the inner end of the waste heat utilization device 2. A locking head 305 is fixedly connected to the front end of the positioning rod 304.

[0037] Reference Figure 2 and Figure 4 As shown, an elastic ring 306 is sleeved on the outer end of the positioning rod 304, and a guide ring 307 is movably connected to the outer side of the elastic ring 306.

[0038] Reference Figure 4 As shown, the guide ring 307 is located at the outer end of the positioning rod 304, the inner end of the waste heat utilization device 2 is provided with an adjustment groove 308, and the inner end of the locking block 303 is provided with a locking groove 309.

[0039] Reference Figure 2 and Figure 5 As shown, the waste heat utilization device 2 has multiple symmetrically distributed assembly racks 310 fixedly connected inside, and each assembly rack 310 has an assembly groove 311 at its inner end.

[0040] The filter plate 211 is engaged with the inner end of a pair of U-shaped mounting brackets 310. When the filter plate 211 needs to be disassembled for maintenance, it can be pulled out from the inner end of the mounting slot 311 for convenient maintenance. Pulling a pair of positioning rods 304 causes them to move in conjunction with the elastic ring 306. The elastic ring 306 moves along with the adjustment of the positioning rods 304. When the positioning rods 304 lose external force, the elastic ring 306 can drive the positioning rods 304 to reset. This makes positioning and disassembly of the positioning rods 304 and the clamp 305 more convenient. 4. The clamp head 305 is moved to separate from the clamp block 303. When the positioning rod 304 moves, the guide ring 307 can move together with the positioning rod 304. The moving positioning rod 304 and the guide ring 307 slide in the inner end of the adjustment groove 308. The adjustment groove 308 limits the guide ring 307, so that the positioning rod 304 will not shift or fall off when the clamp head 305 is adjusted. This allows the connecting cover 301 to be easily disassembled, so that the waste heat utilization device 2 can be easily disassembled and maintained. It is also relatively easy to install, which improves the convenience of the temperature control structure and internal structure maintenance of the flue waste heat utilization structure.

[0041] Reference Figure 1-2 As shown, a housing 201 is fixedly connected to the rear end of the flue pipe body 1. A heat exchange pipe 202 is connected to the inner end of the housing 201. A control valve 203 is fixedly connected to the outer end of the heat exchange pipe 202. A water storage tank 204 is movably connected to the outer end of the heat exchange pipe 202.

[0042] Reference Figure 2-3 As shown, a connecting pipe 205 is fixedly connected to the bottom of the water storage tank 204, a temperature sensor 206 is installed inside the water storage tank 204, a vent pipe 207 is fixedly connected to the top of the tank body 201, and a control valve 208 is fixedly connected to the outer end of the vent pipe 207.

[0043] Reference Figure 2-3 As shown, a connecting plate 209 is fixedly connected to the inner end of the housing 201, and a mounting frame 210 is fixedly connected to the outer end of the housing 201.

[0044] Reference Figure 2 As shown, multiple filter plates 211 are movably connected inside the housing 201.

[0045] The hot airflow in the flue pipe body 1 is guided into the heat exchange tube 202. The heat exchange tube 202 transfers heat energy to the water storage tank 204 through heat transfer. After exchanging heat through the heat exchange tube 202, the water or other fluids inside the water storage tank 204 absorb the waste heat of the flue gas, and the temperature rises, thereby achieving the effect of waste heat recovery. When the temperature sensor 206 senses that the temperature inside the water storage tank 204 has reached the temperature set by the controller 302, the controller 302 controls the second control valve 208 to open. At this time, the vent pipe 207 performs ventilation. In conjunction with the control valve 203 closing the heat exchange tube 202, the structure can control the temperature, avoiding excessively high or low temperatures from affecting the heat exchange efficiency and improving the performance of the flue waste heat utilization structure. Multiple filter plates 211 can effectively filter the heat energy conducted by the flue pipe body 1, allowing the structure to perform waste heat recovery work and reduce blockage.

[0046] Specific implementation process: When the device is in use, the hot airflow in the flue pipe body 1 is guided into the heat exchange pipe 202. The heat exchange pipe 202 transfers heat energy to the water storage tank 204 through heat transfer. After the water storage tank 204 exchanges heat through the heat exchange pipe 202, the water or other fluids inside the water storage tank 204 absorb the waste heat of the flue gas, and the temperature rises, thereby achieving the effect of waste heat recovery. After the temperature sensor 206 senses that the temperature inside the water storage tank 204 has reached the temperature set by the controller 302, the controller 302 controls the second control valve 208 to open. At this time, the vent pipe 207 performs ventilation. In conjunction with the control valve 203 closing the heat exchange pipe 202, the structure can control the temperature.

[0047] When the waste heat recovery device 2 needs maintenance or cleaning, a pair of positioning rods 304 are pulled. The positioning rods 304 move in conjunction with the elastic ring 306. The elastic ring 306 moves along with the adjustment of the positioning rods 304. When the positioning rods 304 lose external force, the elastic ring 306 can drive the positioning rods 304 to reset, making it easier for the positioning rods 304 to drive the clamp 305 for positioning and disassembly. When the positioning rods 304 move, the guide ring 307 can move accordingly. The positioning rod 304 moves together with the guide ring 307, which slides inside the adjustment groove 308. The adjustment groove 308 limits the guide ring 307, so that the positioning rod 304 drives the clamp 305 to adjust its position without displacement or falling off. The positioning rod 304 drives the clamp 305 to move its position and separate from the clamp block 303, so that the connecting cover 301 can be easily disassembled. This makes the waste heat utilization device 2 easy to disassemble and maintain, and also relatively easy to install.
