[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] Example 1, as Figures 1-5 As shown, a high-efficiency sulfur recovery device includes a fixed base 1, with a first cooling box 2 installed above the fixed base 1. The operator connects the air inlet pipe 3 to the sulfur combustion furnace, thereby transporting the combustion gas into the first cooling box 2. Since the temperature of the combustion gas is between 800 and 1300°C, when the gas enters the first cooling box 2, the operator needs to start the delivery pump 25. The delivery pump 25 transports the cooling water in the water storage tank 24 to the annular cooling pipe 6 to cool the recovered gas. The cooling water is circulated through the water outlet pipe 5. When the gas enters the first cooling box 2 from below the wire mesh demister 8, the wire mesh demister 8, in conjunction with multiple sets of wire mesh bodies 11, filters particulate impurities such as carbon black and dust in the gas. The pre-cooled and filtered gas is then transported to the second cooling box 14.
[0025] Example 2, as Figures 1-5As shown, in a high-efficiency sulfur recovery device, when gas enters the second cooling tank 14, cooling water from the water storage tank 24 is transported to the annular cooling pipe 6 inside the second cooling tank 14 via a pump 25 for secondary cooling. An appropriate amount of benzene solution is added to the second cooling tank 14. When the gas enters the second cooling tank 14 from the bottom of the connecting pipe 16, sulfur and other impurities in the gas are adsorbed by the benzene solution. The cooled gas is then transported to the heating pipe 20, where it works with the electric heating tube 22 to heat the water inside the steam heating mechanism 19, forming steam. This steam, heated by 4.0 MPa steam within the sulfur recovery zone, reheats the gas inside the heating pipe 20, reducing H2S, SO2, SX, and other gas components in the inlet gas of the converter body 23 and improving the total sulfur conversion rate.
[0026] It should be noted that this utility model is a high-efficiency sulfur recovery device. In use, the air inlet pipe 3 is connected to the sulfur combustion furnace pipe to collect the gas generated by combustion. Then, multiple sets of wire mesh bodies 11 are placed inside the wire mesh demister 8 in sequence and supported by the set crossbars 9. Then, the set pressure plate 12 is used to confine the wire mesh bodies 11 inside the wire mesh demister 8, thereby completing the assembly of the wire mesh demister 8. Then, the wire mesh demister 8 is placed on the fixed bracket 7, and the annular cooling pipes 6 are fixed respectively. The first cover plate 17 and the second cover plate 18 are positioned below them. At the same time, the inlet pipe 4 and the outlet pipe 5 are symmetrically fixed above the first cover plate 17 and the second cover plate 18. The annular cooling pipe 6 is connected to the inlet pipe 4 and the outlet pipe 5. The inlet pipe 4 and the outlet pipe 5 are connected to the water storage tank 24 through the set hose 27 so that they can complete the circulation cooling. Then, an appropriate amount of benzene solution is added into the interior of the second cooling tank 14. The impurities in the gas are fully filtered by the wire mesh demister 8 to reduce carbon buildup on the upper bed of the converter body 23.
