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
[0039] The specific embodiment of a kind of coal pyrolysis furnace raw gas export condensation and recovery purification and combustion device of the present invention is mainly given in the first section of the fourth part and the first, second, third and fourth sections of the fifth part of the first chapter. Details.
[0040] Part 1 Furnace Coal Proportion and Preparation
[0041] Such as selecting 5 kinds of different coals, they are respectively gas coal, fat coal, coking coal, one-third coking coal, and lean coal mixed first and then sieved and crushed to form coal into the furnace. Furnace coal is also applicable.
[0042] The second part of coal dehydration
[0043] Dehydration is carried out in advance through the incoming coal entering the coal pyrolysis furnace
[0044] The third part into the furnace coal into the coal, preheating, adjustment, cooling
[0045] Section 1 Furnace Coal Feeder Coal Feeding Device is used to input dehydrated furnace coal
[0046] S...

The invention discloses a raw coke oven gas conducting cooling and recovery and purification and combustion device for a coal pyrolyzing furnace. The device comprises a raw coke oven gas conducting device, a raw coke oven gas condensing device, a raw coke oven gas recovery and purification device, and an outer gas heating device. A raw coke oven gas inlet of the raw coke oven gas condensing device communicates with a raw coke oven gas conducting port of a conducting circuit of the raw coke oven gas conducting device through a pipeline; a gas-liquid mixing inlet pipe of the raw coke oven gas recovery and purification device is connected to a gas collecting tube of the raw coke oven gas condensing device through a pipeline; an activated char recovery device of the raw coke oven gas recovery and purification device communicates with a gas blower group through a second air-cooled gas delivery pipe; and a gas blower of a gas reversing device of an outer gas heating device communicates with a purified gas outlet pipe of the activated char recovery device of the raw coke oven gas recovery and purification device through a pipeline. The invention has the characteristic that independent steps including conducting, condensing, purification and recovery and combustion of raw coke oven gas produced during coal pyrolysis in a charring chamber are combined into a complete process.
Description
technical field [0001] The invention relates to a gas derivation condensation, recovery purification and combustion device, in particular to a coal pyrolysis furnace raw gas derivation condensation, recovery purification and combustion device. 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 innovat...
