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
[0025] The specific embodiment of the fire path bow of the coal pyrolysis furnace of the present invention is mainly introduced in detail in the third section of the fourth part below (and refer to the content of the first section).
[0026] Part 1 Furnace Coal Proportion and Preparation
[0027] 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.
[0028] The second part of coal dehydration
[0029] The incoming coal entering the coal pyrolysis furnace is dehydrated in advance throu...

A flame path arc of a coal pyrolysis furnace is provided in a furnace cavity under a carbonization chamber, an internal combustion heating device, and a coke modifying device, and mainly comprises arches and a flame arch central ring wall. A high-temperature combustible waste gas channel 653 is formed in the middle of the flame arch central ring wall, one end of each arch is fixed on a flame arch central ring, the other end is fixed on a furnace body, the arches are distributed radially at intervals at a certain angle around the center of the frame arch central ring wall, the number of the arches being the same as the total number of the main and secondary flame paths of the internal combustion heating device, a third gas inlet branch pipe and an extension channel of a third heat storage cavity are spread in the wall of a previous flame arch, and a first air supplement pipe and a secondary air supplement pipe are spread in the wall of the next adjacent flame arch; and the spreading is performed repeatedly like that.
Description
technical field [0001] The invention relates to a fire bow, in particular to a fire bow in the cavity of 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 gas and ...
