Description

Technical Field

[0001] This utility model relates to a heat dissipation device, and more specifically, to a heat dissipation device for a sulfur incineration furnace. Background Technology

[0002] The sulfur combustion furnace section generates a large amount of heat during production. The original process used water to cool the process gases, but this method is insufficient to meet current production demands. On one hand, the high temperature of the process gases limits production capacity; on the other hand, the heat generated during sulfur combustion accumulates at high temperatures in the production area for extended periods, reducing equipment lifespan and increasing maintenance costs. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing a heat dissipation device for a sulfur incineration furnace that is simple in structure and provides rapid heat exchange and cooling.

[0004] The technical solution of this utility model is implemented as follows: a heat dissipation device for a sulfur incinerator includes a heat dissipation tank connected to the sulfur incinerator. A heat exchange coil for circulating heat transfer oil is detachably installed inside the heat dissipation tank. An oil storage tank for storing heat transfer oil is provided on one side of the heat dissipation tank. The discharge end of the oil storage tank is connected to the inlet end of the heat exchange coil through an oil pump. The outlet end of the heat exchange coil is connected to the return end of the oil storage tank through a pipe connected to an external heat exchange component.

[0005] In the above-mentioned heat dissipation device for a sulfur incinerator, several vertically distributed installation windows are symmetrically arranged on the side walls of both sides of the heat dissipation tank, and a sealing installation plate is provided on each installation window; the heat exchange coil includes a heat exchange tube disposed between two sealing installation plates, and an arc-shaped bend connecting the upper and lower heat exchange tubes is provided on the sealing installation plate.

[0006] In the aforementioned heat dissipation device for a sulfur incinerator, the sealing mounting plate is provided with a mounting flange, a first flange ring is provided at both ends of the heat exchange tube, and a second flange ring is provided on the arc-shaped bend; when the heat exchange tube and the arc-shaped bend are respectively installed on both sides of the sealing mounting plate, the mounting flange is located between the first flange ring and the second flange ring.

[0007] In the aforementioned heat dissipation device for a sulfur incinerator, the heat exchange tube includes a heat-conducting section that projects in an S-shape on a horizontal plane, with the width of the middle portion of the heat-conducting section being greater than the width of both ends; and straight sections are provided at both ends of the heat-conducting section for cooperation with the sealing mounting plate.

[0008] In the aforementioned heat dissipation device for a sulfur incinerator, an air cooler is provided between the outlet end of the heat exchange coil and the return end of the oil storage tank.

[0009] In the aforementioned heat dissipation device for a sulfur incinerator, both the oil storage tank and the heat exchange coil located outside the heat dissipation tank are covered with a heat insulation layer.

[0010] With the above-described structure, this invention uses an oil pump to pump heat transfer oil into the heat exchange coil, which then flows through the heat dissipation tank to absorb and carry away the heat from the high-temperature gas. The heat-carrying oil is then cooled by external heat exchange components and flows back to the storage tank for reuse. The flow of the heat transfer oil effectively removes heat from the heat dissipation tank, improving heat dissipation efficiency, reducing the internal temperature of the tank, and extending its service life.

[0018] See Figure 1-5 As shown, this utility model discloses a heat dissipation device for a sulfur incinerator, comprising a heat dissipation tank 1 connected to the sulfur incinerator. The heat dissipation tank 1 contains a detachable heat exchange coil 2 for circulating heat transfer oil. An oil storage tank 3 for storing the heat transfer oil is located on one side of the heat dissipation tank 1. The outlet end of the oil storage tank 3 is connected to the inlet end of the heat exchange coil 2 via an oil pump 4. The outlet end of the heat exchange coil 2 is connected to the return end of the oil storage tank 3 via a pipe connected to an external heat exchange assembly. The heat transfer oil is pumped into the heat exchange coil by the oil pump, flowing through the interior of the heat dissipation tank to absorb and carry away the heat from the high-temperature gas. The high-temperature heat transfer oil, carrying heat, is cooled by the external heat exchange assembly and then flows back to the oil storage tank for reuse. The flow of the heat transfer oil effectively carries away heat from the interior of the heat dissipation tank, improving heat dissipation efficiency, effectively reducing the internal temperature of the heat dissipation tank, and extending the service life of the heat dissipation tank.

[0019] The outlet end of the heat exchange coil is connected to an external heat exchange component through a pipeline to use waste heat for production hot water or hot air, which is then transported to other production processes or used for domestic water use in the factory area, thereby improving energy utilization.

[0020] Both the oil storage tank 3 and the heat exchange coil 2 located outside the heat dissipation tank 1 are covered with a heat insulation layer. Covering the oil storage tank and the heat exchange coil 2 with a heat insulation layer can improve safety and prevent workers from being burned by accidental contact when they get close.

[0021] In this embodiment, several vertically distributed mounting windows 5 are symmetrically arranged on both side walls of the heat exchange tank 1, and a sealing mounting plate 6 is provided on each mounting window 5. The heat exchange coil 2 includes a heat exchange pipe 2a disposed between two sealing mounting plates 6, and an arc-shaped bend 2b connecting the upper and lower layers of heat exchange pipes 2a is provided on the sealing mounting plate 6. With this structure, the heat exchange coil is installed in a modular, separate manner, which is convenient for disassembly and assembly. If one section of the heat exchange coil is damaged, it can be replaced individually, effectively saving costs. Moreover, the size of the mounting windows opened on the side wall of the heat exchange tank can be reduced, thus reducing the possibility of leakage.

[0022] In this embodiment, preferably, the sealing mounting plate 6 is provided with a mounting flange 2c, a first flange ring 2d is provided at both ends of the heat exchange tube 2a, and a second flange ring 2e is provided on the arc-shaped bend 2b; when the heat exchange tube 2a and the arc-shaped bend 2b are respectively installed on both sides of the sealing mounting plate 6, the mounting flange 2c is located between the first flange ring 2d and the second flange ring 2e. This structure facilitates the installation and fixing of the heat exchange tube and the arc-shaped bend.

[0023] More preferably, the heat exchange tube 2a includes a heat-conducting section 2f that projects in an S-shape on a horizontal plane, with the width of the middle portion of the heat-conducting section 2f greater than the width of its two ends; straight sections 2g are provided at both ends of the heat-conducting section 2f for mating with the sealing mounting plate 6. The maximum horizontal width of the heat-conducting section is adapted to the width of the installation window, ensuring that it can be installed into the heat sink through the installation window. This structure can increase the contact area between the heat exchange tube and the high-temperature gas inside the heat sink, thereby improving the heat exchange efficiency.

[0024] In this embodiment, an air cooler 7 is provided between the outlet end of the heat exchange coil 2 and the return end of the oil storage tank 3. The air cooler is installed between the outlet end of the heat exchange coil and the return end of the oil storage tank via a three-way pipe and a valve. When there is a failure of the external heat exchange components, when there is no need to utilize waste heat, or when the heat transfer oil needs to be circulated quickly, the flow direction of the heat transfer oil is changed by the valve so that it passes through the air cooler for rapid cooling and returns to the oil storage tank for the next circulation.

[0025] During operation, the high-temperature gas in the sulfur incinerator enters the heat dissipation tank. The oil pump pumps the heat transfer oil in the storage tank into the heat transfer coil. After the heat transfer oil absorbs the heat carried by the high-temperature gas through the storage tank, it flows to the external heat exchange components or air cooler for cooling and then returns to the storage tank to wait for the next cycle.

[0026] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
