Description

Technical Field

[0001] This application relates to the field of waste heat recovery equipment technology, and in particular to a waste heat recovery device for a high-efficiency infrared glass drying tunnel. Background Technology

[0002] A drying oven is a device used for drying processing. Wet materials are placed inside the drying oven, and high-temperature gas is injected into the oven. The high-temperature gas dries the wet materials into dry materials inside the oven. The dried gas is then directly discharged from the drying oven. Although the high-temperature gas loses heat while drying the wet materials inside the oven, the discharged gas still has a certain temperature. Directly discharging this gas results in the direct waste of this heat, reducing the utilization rate of resources. Therefore, a waste heat recovery device is needed to recover the heat in the discharged gas.

[0003] A search revealed a patent document with authorization announcement number CN105371643A, which discloses a waste heat recovery device for a drying oven. The device includes a heat exchanger, comprising a shell and a fresh air channel and a hot exhaust gas channel within the shell. A heat exchange device is installed between the fresh air channel and the hot exhaust gas channel, utilizing the principle of heat exchange to absorb the heat from the exhaust gas flowing through the hot exhaust gas channel. This waste heat recovery device utilizes the principle of circulating heat conduction exchange to achieve waste heat recovery and utilization, resulting in energy saving and environmental protection. The structure is a square box type, simple in design, easy to clean and maintain, and occupies little space when placed above the drying oven. After the exhaust gas passes through the waste heat recovery device, the temperature of the pipe wall is reduced, thus reducing the heat radiation of the exhaust gas system to the air, achieving an overall energy saving of approximately 20%.

[0004] In practical use, it was found that existing devices cannot divert the hot waste gas during hot waste gas recovery, which easily leads to a slow heat exchange process and thus affects work efficiency. Therefore, we propose a high-efficiency infrared glass drying tunnel waste heat recovery device to solve the above problems. Utility Model Content

[0034] Specifically, the transmission mechanism includes two transmission wheels 601 and a transmission belt 602. The transmission wheels 601 are fixedly sleeved on both the rotating rod 301 and the rotating shaft 9. The transmission wheels 601 are located in the corresponding side box 5, and the same transmission belt 602 is sleeved on the two transmission wheels 601.

[0035] Specifically, the gear mechanism includes two bevel gears 901. Both the right end of the fan shaft 402 and the rotating shaft 9 are fixedly fitted with bevel gears 901. Both bevel gears 901 are located inside the exhaust pipe 4 and mesh with each other.

[0036] Specifically, the heat exchange mechanism includes two fixed plates 201, a heat exchange tube 202, heat-conducting fins 203, and vent holes 204. Two fixed plates 201 are fixedly installed on the inner wall of the recovery box 2. The fixed plates 201 are located on the left side of the clamping seat 8.

[0037] Specifically, the heat storage mechanism includes a heat storage box 7 and a heat transfer pipe 701. The heat storage box 7 is installed at the bottom of the recovery box 2, and the same heat transfer pipe 701 is installed between the heat storage box 7 and the heat exchange pipe 202.

[0038] Specifically, the clamping mechanism includes a screw 801 and a clamping block 802.

[0039] In this application, during operation, the high-temperature exhaust gas generated during the operation of the glass drying tunnel 1, under thermal pressure, flows directionally into the recovery box 2 through the inlet pipe 3. When the exhaust gas flows in the inlet pipe 3, its kinetic energy impacts the blades 303 on the impeller 302. According to the momentum theorem in fluid mechanics, the impeller 302, together with the rotating rod 301, rotates. The rotation of the rotating rod 301 transmits power smoothly and efficiently to the rotating shaft 9 through a belt drive mechanism consisting of a transmission wheel 601 and a transmission belt 602. The rotating shaft 9 then transmits power through two... The bevel gear transmission pair composed of bevel gear 901 drives the fan shaft 402 to rotate. Utilizing the precision and stability of gear transmission, the fan blade 403 at the end of the fan shaft 402 rotates at high speed. According to the principle of aerodynamics, the air pressure difference generated by the rotation of the fan blade 403 produces a drafting effect, which can accelerate the flow of exhaust gas throughout the system, thereby improving the heat exchange efficiency of the exhaust gas. It is worth noting that the structural design of the blade 303 and the impact angle of the airflow in the intake pipe 3 determine that the rotation direction of the impeller 302 is fixed and consistent.

[0040] After the exhaust gas enters the recovery box 2, it comes into full contact with the heat exchange tube 202 and its surface heat-conducting fins 203, which are fixed and supported by the two fixed plates 201, through the evenly spaced ventilation holes 204 on the fixed plate 201. At this time, based on the heat transfer principles of heat conduction and heat convection, the heat in the exhaust gas is quickly transferred to the heat exchange tube 202 and the heat-conducting fins 203. The setting of the heat-conducting fins 203 greatly increases the heat exchange area, which can significantly improve the heat exchange efficiency. The heat is transferred stably and efficiently to the heat storage box 7 located at the bottom of the recovery box 2 through the heat-conducting pipe 701 according to the law of heat conduction, thereby realizing the effective recovery and utilization of waste heat.

[0041] At this time, the exhaust gas continues to pass through the filter layer 10 fixed in the clamping seat 8 by the clamping mechanism consisting of the screw 801 and the clamping block 802. The filter layer 10 can effectively intercept and separate particulate impurities, dust and other particles in the exhaust gas according to the principle of filtration and separation, so as to ensure that the exhaust gas discharged through the exhaust pipe 4 is relatively clean and to reduce the pollution to the environment.
