Technical Field
[0001] The utility model relates to the technical field of waste heat recovery, in particular to a sulfuric acid dilution waste heat recovery device. Background Art
[0002] Sulfuric acid production is an energy-intensive process, especially in the dilution stage of sulfuric acid, which generates a lot of waste heat. If this waste heat is not recycled, it will not only cause energy waste, but also increase the consumption of cooling water and corresponding power, thereby increasing production costs. With the increasing prominence of energy issues, how to use energy efficiently, recycle various waste heat, and reduce the pollution of the environment caused by exhaust heat has become the focus of people's attention.
[0003] Because hot gases at different temperatures require different heat exchange areas, the contact area and amount must be considered when designing a heat exchange device to achieve efficient heat exchange. Since the hot gas is stationary when it enters the device, the temperature inside the device cannot be evenly distributed, which results in reduced utilization of waste heat during sulfuric acid dilution, leading to waste of waste heat. Utility Model Content

[0024] See also Figures 1 to 4 The utility model provides a technical solution: a connecting box 5, a motor 10 is fixedly connected to the outside of the connecting box 5, a crank 11 is provided at the output end of the motor 10, a sliding box 7 is slidably connected to the outside of the crank 11, the sliding box 7 and the connecting box 5 are slidably connected, the sliding box 7 is fixedly connected to the outside of the external pipe 8, a vent hole 18 is provided on the outside of the connecting box 5, a heat conducting plate 17 is fixedly connected to the outside of the connecting box 5, and a through hole 20 is provided on the outside of the sliding box 7; a slide rail 12 is fixedly connected to the outside of the sliding box 7, the crank 11 is slidably connected to the outside of the slide rail 12, and the crank 11 and the sliding box 7 are slidably connected through the slide rail 12; a slide groove 6 is provided on the outside of the connecting box 5, the slide groove 6 is slidably connected to the outside of the sliding box 7, and the sliding box 7 and the connecting box 5 are slidably connected through the slide groove 6.
[0025] Because the output end of the motor 10 is provided with a crank 11, and the crank 11 is slidably connected to the sliding box 7 by the slide rail 12, the staff starts the motor 10, so that the sliding box 7 slides on the connecting box 5, thereby controlling the through hole 20 opened on the sliding box 7 to be aligned with the air vent 18 opened on the connecting box 5, so that the hot air enters the interior of the connecting box 5 through the external pipe 8. Since the connecting box 5 is provided with a plurality of air vents 18, a heat conducting plate 17 is fixedly connected next to the air vent 18. Since the utilization rate of waste heat is related to the contact area between the hot gas and the heat conducting plate 17, the staff can control the overlap of the through hole 20 and the air vent 18, and the staff can adjust the contact area according to actual needs. When processing high-temperature gas, the contact area of heat exchange can be increased to reduce the waste of waste heat. When processing low-temperature gas, it can reduce the contact area of heat exchange, thereby reducing thermal resistance and ensuring heat exchange efficiency, so that the hot gas can contact more heat conducting plates 17.

The first bevel gear 14 and the second bevel gear 15 are meshed and connected, and the rotating shaft 13 and the main shaft 19 are meshed and connected through the first bevel gear 14 and the second bevel gear 15; the connecting box 5 is fixedly connected to the outside of the connecting pipe 4, and the connecting pipe 4 is fixedly connected to the outside of the connecting box 5. The box 2 and the connecting box 5 are fixedly connected through the connecting pipe 4; the connecting box 5 is fixedly connected to the outside of the base 1, and the base 1 and the box 2 are fixedly connected.
[0028] Since the connecting box 5 is slidably connected to the sliding box 7 via the slide groove 6, and the sliding box 7 is meshedly connected to the gear 9, the gear 9 is fixedly connected to the rotating shaft 13, and the rotating shaft 13 is meshedly connected to the main shaft 19 via the first bevel gear 14 and the second bevel gear 15, the rotating shaft 13 drives the main shaft 19 to rotate, and the stirring blades 16 can disturb the hot air inside the connecting box 5, so that the gas temperature inside the connecting box 5 is more balanced, the heat exchange efficiency is guaranteed, and the utilization rate of the waste heat is higher.

Since the connecting box 5 is provided with a plurality of air vents 18, the side of the air vent 18 is fixedly connected with a heat conducting plate 17. Due to the utilization rate of the waste heat and the heat conduction between the hot air and the heat conduction plate 17, the heat conduction plate 17 can be used to connect the connecting box 5 to the connecting box 5. The contact area of the plate 17 is related to the contact area of the plate 17, so the staff can control the overlap of the through hole 20 and the air vent 18, so that the hot air can contact more heat-conducting plates 17, so that the utilization rate of the waste heat can be higher. At the same time, when the sliding box 7 slides on the connecting box 5, the sliding box 7 and the driving gear 9 rotate, and the sliding box 7 is fixedly connected to the rotating shaft 13, so that the rotating shaft 13 drives the main shaft 19 to rotate, and the stirring blades 16 can disturb the hot air inside the connecting box 5, so that the gas temperature inside the connecting box 5 is more balanced, thereby ensuring the heat exchange efficiency.
