The automatic control device can be used for controlling the instruments for techniques of dehydration, coal feeding, preheating, carbonization, coke modification, dry quenching and crude gas guiding.

Description

technical field [0001] The invention relates to an automatic control device, in particular to an automatic control device for a thermal cycle continuous coal pyrolysis furnace. Background technique [0002] At present, most coal pyrolysis furnaces (coke ovens) on the market adopt batch-type coking, and the process steps such as the proportion of coal into the furnace, dehydration, coal feeding, preheating, carbonization, coke reforming, and CDQ are relatively independent and cannot be carried out. Continuous production, low production efficiency; In addition, the raw coal gas produced in the coal pyrolysis process contains many useful components, such as H 2 S, HCH and other acid gases, NH 3 Alkaline gas, tar, benzene, naphthalene, washing oil and other organic substances do not have a complete process for exporting, recovering and purifying raw gas. [0003] This impels the inventors to explore and innovate a complete set of continuous coking and a complete process for ex...
