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
[0024] The specific embodiment of the raw coal gas exporting device of the coal pyrolysis furnace of the present invention is mainly introduced in detail in the first section of the first chapter of the fifth part below.
[0025] Part I Furnace Coal Proportion and Preparation
[0026] The coal pyrolysis furnace involved in the present invention can obtain cokes of different grades according to different proportions of coals fed into the furnace.
[0027] The steps are as follows: 1) 5 kinds of different coals are selected, which are respectively gas coal, fat coal, coking coal, one-third coking coal and lean coal. 2) Gas coal 20%~40%; fat coal 10%~20%; coking coal 10%~20%; one-third coking coal 15%~30%; lean coal 10%~15%, first mix and then sieve Broken until the broken particles reach below 5mm to form coal into the furnace. Of course, the coal pyrolysis furnace of the present invention is equally applicable to coal into the furnace with other proportions and particle sizes,...

The invention discloses a crude gas guiding device for a coal pyrolyzing furnace. The crude gas guiding device comprises a crude gas centralizing chamber, an inner guiding channel, an outer guiding channel, a main guiding channel and an annular guiding channel; the crude gas centralizing chamber is arranged on the top of a coking chamber of the coal pyrolyzing furnace, and the crude gas centralizing chamber and the coking chamber are integrally formed; the inner guiding channel is arranged in a flame path partition wall and penetrates through an inner ring wall of the coking chamber to lead to the coking chamber, and the outlet of the inner guiding channel penetrates through the inner ring wall to lead to the crude gas centralizing chamber; the outer guiding channel is arranged in an outer wall of the furnace body, a lower outer guiding channel inlet and an upper outer guiding channel inlet of the outer guiding channel penetrate through an outer ring wall of the coking chamber to lead to the coking chamber, and the outlet of the outer guiding channel penetrates the outer ring wall to lead to the crude gas centralizing chamber; and the main guiding channel is arranged in the outer wall of the furnace body to be communicated with the crude gas centralizing chamber, and extends upwards into the annular guiding channel arranged at the upper part of the outer wall of the furnace body, and the annular guiding channel is provided with a crude gas guiding port. The crude gas generated in the process of coal pyrolysis can be successfully guided by the crude gas guiding device.
Description
technical field [0001] The invention relates to a gas exporting device, in particular to a raw coal gas exporting device 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 pur...
