Description

Technical Field

[0001] The invention relates to the technical field of coal, in particular to a high-efficiency energy-saving drying device for coal washing and processing. Background Art

[0002] Coal is praised as black gold and food for industry. It has been one of the main energy sources used by the human world since the 18th century. Since the 21st century, although the value of coal is not as high as before, it has been one of the indispensable sources of energy for our production and life for a long time. The supply of coal is also related to the stability of the development of my country's industry and even the entire society. The supply security of coal is also the most important part of my country's energy security. Coal is the fossil fuel with the richest reserves and the widest distribution on the earth. The elements that make up the organic matter of coal are mainly carbon, hydrogen, oxygen, nitrogen and sulfur. In addition, there are very small amounts of phosphorus, fluorine, chlorine and arsenic. The deeper the coalification degree, the higher the carbon content and the lower the hydrogen and oxygen content. Carbon and hydrogen are elements that generate heat during coal combustion, and oxygen is a combustion-supporting element. When coal burns, nitrogen does not generate heat and is converted into nitrogen oxides and ammonia at high temperatures and precipitated in a free state. Sulfur, phosphorus, fluorine, chlorine and arsenic are harmful components in coal, among which sulfur is the most important.

[0003] With the intensification of the global energy crisis and the improvement of environmental protection requirements, energy conservation and consumption reduction have become important issues in the coal industry.
