Problems solved by technology
[0002] Most coal pyrolysis furnaces (coke ovens) currently on the market adopt batch-type coking. Coke upgrading, dry quenching and other process steps are relatively independent, continuous production cannot be carried out, and production efficiency is low; in addition, the raw coal gas generated during coal pyrolysis contains many useful components, such as H2S , HCH and other acid gases, NH3 basic gas, tar, benzene, naphthalene, washing oil and other organic substances, there is no complete process for exporting, recycling and purifying raw gas

Embodiment Construction
[0028] A specific embodiment of a continuous coking device for a coal pyrolysis furnace of the present invention is mainly introduced in detail in the following entire fourth part.
[0029] Part 1 Furnace Coal Proportion and Preparation
[0030] If 5 different coals are selected, they are respectively gas coal, fat coal, coking coal, one-third coking coal, and lean coal, which are first mixed and then sieved and crushed until the broken particles reach below 5mm to form the furnace coal. Of course, the coal of the present invention is heated The decomposing furnace is equally applicable to other proportions and particle sizes of the furnace-feeding coal, and does not constitute a limitation to the furnace-feeding coal powder required by the coal pyrolysis furnace of the present invention.
[0031] Part 2 Dehydration of incoming coal
[0032] The incoming coal entering the coal pyrolysis furnace is dehydrated in advance through the incoming coal dehydration device, which plays t...

The invention discloses a continuous coking device of a coal pyrolysis furnace. The device comprises a furnace body, a coal pyrolysis and carbonization device, a coke modifying device and a coke dry quenching device, wherein the coal pyrolysis and carbonization device, the coke modifying device and the coke dry quenching device are integrally formed on the furnace body from top to bottom; the coal pyrolysis and carbonization device is used for pyrolyzing and carbonizing the coal as fired; the coke modifying device is used for modifying the coke which is obtained after pyrolysis and carbonization and directly falls into the coke modifying device; and the coke dry quenching device 7 is used for dry quenching the coke which has been subjected to modification and directly falls into the coke dry quenching device. The continuous coking device is characterized in that the coal pyrolysis and carbonization, modification and dry quenching processes are integrated in the same coal heat furnace body, so that carbonization, modification and dry quenching can be continuously achieved, the production efficiency is improved and the equipment becomes simple.
Description
technical field [0001] The invention relates to a coking device, in particular to a continuous coking device for a 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 exporting, recovering and purifying raw ...
