Problems solved by technology

But as mentioned above, only by heating coal with microwave irradiation, the inorganic sulfur in coal decomposes to release H 2 S and SO 2 The gas, as well as the elemental sulfur generated on the surface of the coal, accumulates on the surface of the coal, hindering the escape of the decomposed sulfur-containing components, and affecting the effect of microwave irradiation treatment
Moreover, only using microwave irradiation to heat coal has no obvious effect on the removal of organic sulfur in coal.

Abstract

The invention relates to a device and a method for generating clean coal by means of quick total sulfur treatment of coal. Total sulfur in raw coal is subjected to low-temperature negative-pressure treatment by means of vacuum negative pressure combined with microwave heating to quickly remove evaporable harmful substances in the raw coal, and pyrite in the coal is quickly translated into pyrrhotite and troilite which are higher in paramagnetism by means of microwave irradiation so as to be convenient to remove more effectively in subsequent magnetic separation. The device and the method can be also applied to heating, drying and removal of evaporable harmful substances in industries of textile, dyeing, printing, food, medicine, chemical engineering, mining, papermaking and the like, such as quick removal of harmful substances like formaldehyde contained in textiles and garments and dimethylbenzene contained in artificial boards.

Description

Technical field: [0001] The present invention relates to the technical field of physical desulfurization of raw coal, to the technical field of combination of small and medium power microwave sources, to the technical field of vacuum negative pressure drying, and to the technical field of low-temperature drying using a combined microwave device combined with a vacuum negative pressure device. A device and method for quickly processing raw coal full sulfur to generate clean coal. Background technique: [0002] Coal is one of the most abundant fossil fuels on Earth, accounting for about two-thirds of the world's total energy reserves. As far as my country's energy structure is concerned, it is still dominated by coal-burning, which determines that the typical air pollution in our country is the emission of SO 2 Soot-type pollution characterized by smoke and dust. The presence of sulfur in coal can also affect the quality of coal processed products. Therefore, with the enhan...
