Description

Technical Field

[0001] The utility model relates to the technical field of raw coal gas impurity removal, in particular to a raw coal gas impurity removal device used for blue coke production. Background Art

[0002] Semi-coke is made by burning clean coal blocks. As a new type of carbon material, it has the characteristics of high fixed carbon, high specific resistivity, 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 calcium carbide, ferroalloys, ferrosilicon, silicon carbide and other products, becoming an irreplaceable carbon material. Semi-coke can replace coke (metallurgical coke) and is widely used in chemical, smelting, gasification and other industries. Raw coal gas refers to dusty coal gas. The coal gas (raw coal gas) produced by coal coking in the carbonization chamber contains a large amount of chemical products. Raw coal gas cannot be used directly and must be dust-removed.

[0003] At present, some devices treat coal gas dust reduction by spraying water on the coal gas, so that the spraying water and coal gas are mixed to degrade the dust in the coal gas. However, the spraying water will lower the temperature of the coal gas, so that the tar in the coal gas will precipitate and adhere to the inside of the box and pipeline, causing pipeline blockage and affecting the transmission effect of the coal gas.
