Technical Field

[0001] The utility model belongs to the technical field of semi-coke gas fans, and specifically relates to a tar removal device for the shaft seal of a double-supported semi-coke gas fan. Background Technique

[0002] Semi-coke is made by firing fine coal blocks. As a new type of carbon material, with its characteristics of high fixed carbon, high specific resistance, high chemical activity, low ash content, low aluminum, low sulfur, and low phosphorus, it has gradually replaced metallurgical coke and is widely used in the production of products such as calcium carbide, ferroalloy, ferrosilicon, and silicon carbide, becoming an irreplaceable carbon material. Semi-coke can replace coke (metallurgical coke) and is widely used in industries such as chemical engineering, smelting, and gas production.

[0003] Semi-coke gas generally contains a small amount of coal tar and water vapor. When the fan operates normally, coal tar will continuously accumulate at the shaft seal. After reaching a certain amount, it will overflow outward along the main shaft. Along with the rotation of the main shaft, the coal tar will splash everywhere. Some will fall on the equipment and some will be suspended in the air, which will endanger physical health and pollute the environment. At present, the problem of tar leakage in semi-coke gas fans is widespread, and this technical problem has not been completely solved yet. For this reason, this application proposes a tar removal device for the shaft seal of a double-supported semi-coke gas fan. Content of the Utility Model
