Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, specifically a building waste heat recovery and heating device. Background Technology

[0002] Building waste heat recovery and heating devices are designed to efficiently collect various waste heat resources within buildings and convert them into stable heating energy, providing a comfortable and warm indoor environment for buildings while significantly reducing energy consumption and operating costs, thus helping buildings achieve energy conservation, emission reduction, and sustainable development goals.

[0003] In existing equipment, industrial steam is directly absorbed and then introduced into water. The resulting hot water is used for boiler water supply or employee bathing water. However, direct absorption generates vibration and noise.

[0004] As disclosed in announcement number CN208282233U, a waste heat recovery heating device has a simple structure, low application cost, and obvious effect. The connecting pipe between the air inlet and outlet is equipped with an air outlet to reduce the vibration and noise generated by direct absorption into the water and to make the heating more uniform. When there is a lot of steam, the steam can be diverted to heat the water in the storage tank. The solenoid valve and water level sensor can automatically control the water storage capacity of the storage tank and the heating water tank.

[0005] However, the device is unable to filter impurities in the steam of industrial buildings during use, which causes the impurities to clog the steam pipes and affect the efficiency of waste heat recovery.

[0006] Therefore, we urgently need to provide a building waste heat recovery and heating device. Utility Model Content

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. Example

[0027] Current technologies are unable to filter impurities from industrial building steam, leading to blockages in steam pipes and impacting waste heat recovery efficiency. Please refer to [link to relevant documentation]. Figures 1-5 The embodiment provides a building waste heat recovery and heating device capable of filtering impurities in steam. This building waste heat recovery and heating device includes a housing 1, with heat exchange and heating devices installed inside and outside the housing 1.

[0028] The waste heat treatment mechanism is located on the left side of the box 1, the disassembly mechanism is located on the left side of the box 1, the heating mechanism is located on the right side of the box 1, and the stirring mechanism is located inside the box 1.

[0029] The waste heat treatment mechanism includes a treatment box 201, a hot air inlet 202, a heat exchange tube 203, a top cover 204, a bottom plate 205, a filter screen 206, a telescopic component 207, and a brush plate 208. The treatment box 201 is fixedly installed on the left side of the box body 1. The hot air inlet 202 is connected to the left side of the treatment box 201. One end of the heat exchange tube 203 is connected to the right side of the treatment box 201 and is located inside the box body 1. The top cover 204 is installed on the top of the treatment box 201. The bottom plate 205 is installed at the bottom inside the top cover 204. The upper surface of 05 has a groove, and the lower end of the filter screen 206 is inserted into the groove. Steam generated by the waste heat of the building is introduced into the treatment box 201 through the hot air inlet 202, and then the filter screen 206 filters the impurities in the steam to prevent the impurities from clogging the heat exchange tube 203. The lower end of the filter screen 206 is inserted into the upper part of the bottom plate 205. The telescopic component 207 is fixedly installed on the top of the top cover 204. The telescopic component 207 is an electric push rod, and the brush plate 208 is fixedly installed on the bottom of the telescopic component 207.

[0030] To facilitate the disassembly of the filter screen 206 and the cleaning of impurities inside the treatment box 201, this device is also equipped with a disassembly mechanism. The disassembly mechanism includes a handle 301, a threaded rod 302, a pressure plate 303, a knob 304, a locking rod 305, a connecting rod 306, a spring 307, and a clamping element 308.

The pressure plate 303 is fixedly installed at the end of the threaded rod 302 near the filter screen 206. The knob 304 is fixedly installed on the outside of the threaded rod 302. Rotating the knob 304 causes the threaded rod 302 to rotate, thus engaging the handle 301.

The end of the clamping member 308 away from the connecting rod 306 has a clamping hole, and the diameter of the clamping hole is equal to the diameter of the clamping rod 305. By engaging and disengaging the clamping member 308 and the clamping rod 305, the top cover 204 can be installed and disassembled, thereby enabling the removal and installation of the filter screen 206.

[0031] To utilize waste heat and improve heating efficiency, this device also includes a heating mechanism. This mechanism comprises a water tank 401, a first pump body 402, an inlet pipe 403, a heating pipe 404, a circulation pipe 405, a second pump body 406, and heat dissipation fins 407. The water tank 401 is installed on the left side of the back of the housing 1. The first pump body 402 is installed on top of the water tank 401. The inlet pipe 403 is connected to the top of the first pump body 402. One end of the heating pipe 404 is connected to the lower right side of the housing 1, and the heating pipe 404 is located indoors. The end of the circulation pipe 405 away from the heating pipe 404 is connected to the second pump body 406. The heating mechanism is activated by starting the first pump body 402. Cold water flows into the housing 1 through the inlet pipe 403 and exchanges heat with the heat exchange pipe 203. Hot water then flows out through the heating pipe 404 and, with the help of the heat dissipation fins 407, dissipates heat into the room, thus achieving heating. Subsequently, the hot water in the heating pipe 404 flows back into the water tank 401 through the circulation pipe 405 under the action of the second pump body 406, realizing the recycling of water. The circulation pipe 405 is connected to the other end of the heating pipe 404. The second pump body 406 is installed on the right side of the water tank 401, and the heat dissipation fins 407 are installed on the outside of the heating pipe 404. The heat dissipation fins 407 accelerate the heat dissipation of the heating pipe 404, thereby improving the heating effect. Example

[0032] Based on Example 1, please refer to Figures 1-5To improve the heat exchange efficiency between the cold water and the heat exchange tube 203 and to enhance the utilization efficiency of waste heat from steam in the building industry, this device is also equipped with a stirring mechanism. The stirring mechanism includes a motor 501, a stirring rod 502, a stirring rod 503, and a transmission component 504. The motor 501 is fixedly installed on the right side of the housing 1. The stirring rod 502 is fixedly installed at the output end of the motor 501. The stirring rod 503 is rotatably connected inside the housing 1 and located in front of the stirring rod 502. The transmission component 504 is installed on the right side of the stirring rod 502 and the stirring rod 503. The transmission component 504 includes a belt and a pulley. The pulley is fixedly installed on the outside of the right end of the stirring rod 502 and the stirring rod 503. The belt is sleeved on the outside of the two pulleys. By starting the motor 501, the stirring rod 502 is driven to rotate. Under the action of the pulley and the belt, the stirring rod 503 is driven to rotate, which disturbs the cold water and improves the heat exchange efficiency between the cold water and the heat exchange tube 203.

[0033] In operation, steam generated in the construction industry is introduced into the treatment tank 201 through the hot air inlet 202. After being filtered by the filter screen 206, it enters the heat exchange tube 203. Simultaneously, pump body one 402 is started, allowing cold water to flow into the tank 1 through the water inlet pipe 403. Motor 501 is also started, driving stirring rod one 502 to rotate. Under the action of transmission component 504, stirring rod two 503 rotates simultaneously, stirring the cold water in the tank 1, thereby improving the heat exchange efficiency between the heat exchange tube 203 and the cold water. The heated water flows along the heating pipe 404, and with the help of heat dissipation fins 407, the heat in the hot water is dissipated into the room, thus achieving heating. Subsequently, pump body two 406 is started, causing the hot water in the heating pipe 404 to flow back into the water tank 401 through the circulation pipe 405, achieving water circulation. When the filter screen 206 becomes clogged, the telescopic component 207 is activated to push the brush plate 208 up and down, sweeping away the impurities attached to the surface of the filter screen 206 and causing them to fall onto the top of the base plate 205, thereby preventing the filter screen 206 from becoming clogged and accelerating the passage of steam through the filter screen 206. When the filter screen 206 needs to be disassembled and replaced, push the clamping component 308 outward away from the clamping rod 305, then remove the top cover 204 upward, and then pull the handle 301 to remove the base plate 205 and the filter screen 206 from the inside of the processing box 201. Then turn the knob 304 to drive the threaded rod 302 to rotate and connect with the handle 301, so that the pressure plate 303 is away from the filter screen 206, and then the filter screen 206 can be removed. The filter screen 206 can be installed in the same way.
