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

[0054] The specific embodiment of a comprehensive recycling device for coal pyrolysis gas of the present invention is mainly introduced in detail below.

[0055] Part 1 Furnace Coal Proportion and Preparation

[0056] 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.

[0057]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, and does not constitute a restriction on the required coal powder fo...

Abstract

The invention discloses a comprehensive recycling device for coal pyrolysis gas. The comprehensive recycling device comprises a waste gas dehydrator, a preheating device, a coal pyrolyzing and carbonizing device, a coke modifying device, a dry quenching device, a crude gas guiding device, a crude gas condensing device, a dry-process active coke recycler, an active coke regenerator and a tubular heat exchanger. According to the invention, the guiding, purifying and recovering of crude gas and processes of combusting, dry quenching, coke modifying, preheating, dehydrating, active coke regenerating and the like of purified and recovered clean gas are connected into a whole in series, so that a complete process of guiding, recovering, purifying and recycling of the crude gas is realized, and the coking cost is lowered.

Description

technical field [0001] The invention relates to a gas utilization device, in particular to a comprehensive recycling device for coal pyrolysis gas. 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 purif...
