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

[0031] A specific embodiment of a continuous coking method for a coal pyrolysis furnace of the present invention is mainly introduced in detail in the following entire fourth part.

[0032] Part 1 Furnace Coal Proportion and Preparation

[0033] 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.

[0034] Part 2 Dehydration of incoming coal

[0035] The incoming coal entering the coal pyrolysis furnace is dehydrated in advance through the incoming coal dehydration device, which plays...

Abstract

The invention discloses a continuous coking method for a coal pyrolysis furnace. The steps for realizing the method are as follows: (1) the coal fed into the furnace enters the carbonization chamber of a coal pyrolysis carbonization device and is heated to undergo pyrolysis; (2) the pyrolysis is completed The coal that enters the furnace directly falls into the coke reforming device for coke reforming; (3) uses the low-temperature waste gas after combustion to dry the coke that falls directly into the CDQ device after reforming, and at the same time generates high temperature Combustible gas; (4) Finally, discharge the dry-quenched coke from the dry-quenching device. The continuous coking of the present invention is characterized in that coal pyrolysis carbonization, reforming and dry quenching processes are integrated in the same coal-fired furnace body, so that carbonization, reforming and dry quenching can be realized continuously, with high production efficiency and simple equipment.

Description

technical field [0001] The invention relates to a coking method, in particular to a continuous coking method 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 ...
