Embodiment 1

[0029] Embodiment 1: the coke oven coking method that improves chemical industry coke with long-flame coal proportioning described in the present embodiment is characterized in that it is carried out according to the following steps:

[0030] a. Transport the long-flame coal to the coking plant, and directly carry out secondary crushing after unloading the coal, from 800mm to 100mm and then to 5mm, and then send it to the mechanized coal yard for stacking; during the production process, the coal is taken by the reclaimer , sent to the storage and distribution warehouse and mixed with the binder at a ratio of 16:1;

[0031] b. Pre-crushing the long-flame coal mixed with the binder until the particle size is less than 5mm, accounting for 85%, and fully mixing the weakly bonded long-flame coal with the binder during the crushing process, so that the original bonding index The long-flame coal with only 9 is increased to 35; the long-flame coal after pre-crushing and mixing the bin...

Embodiment 2

[0035] Embodiment 2: The coke oven coking method described in this embodiment to improve the long-flame coal proportioning for chemical coke described in this embodiment is characterized in that it is carried out according to the following steps:

[0036] a. Transport the long-flame coal to the coking plant, and directly carry out secondary crushing after unloading the coal, from 800mm to 100mm and then to 5mm, and then send it to the mechanized coal yard for stacking; during the production process, the coal is taken by the reclaimer , sent to the storage and distribution warehouse and mixed with the binder at a ratio of 20:1;

[0037] b. Pre-crushing the long-flame coal mixed with the binder until the particle size is less than 5mm, accounting for 85%, and fully mixing the weakly bonded long-flame coal with the binder during the crushing process, so that the original bonding index The long-flame coal with only 9 is increased to 40; the long-flame coal after pre-crushing and m...

Embodiment 3

[0041] Embodiment 3: The coke oven coking method described in this embodiment to improve the long-flame coal proportioning for chemical coke described in this embodiment is characterized in that it is carried out according to the following steps:

[0042] a. Transport the long-flame coal to the coking plant, and directly carry out secondary crushing after unloading the coal, from 800mm to 300mm and then to 50mm, and then send it to the mechanized coal yard for stacking; during the production process, the coal is taken by the reclaimer , sent to the storage and distribution warehouse and mixed with the binder at a ratio of 18:1;

[0043] b. Pre-crushing the long-flame coal mixed with binder to a particle size of 5 mm, and fully mix the weakly bonded long-flame coal with the binder during the crushing process, so that the original bond index is only 9 long The flame coal is increased to 37; the long-flame coal mixed with the binder is sent to the coal blending room through pre-c...

Abstract

The invention relates to a coke oven coking method for improving a ratio of long flame coal for chemical coke. The method comprises the following steps: a, performing secondary crushing on long flame coal, and mixing the long flame coal with an adhesive in a storage warehouse; b, performing pre-grinding on the long flame coal mixed with the adhesive, feeding the coal into a coal blending chamber, improving a ratio of the long flame coal mixed with the adhesive to 80 percent, adjusting a gas-fat coal ratio with high adhesiveness to 20 percent, and feeding the coal into a crusher for crushing after mixing; c, performing primary water injection on the prepared mixed coal, crushing the coal in a crusher chamber, performing secondary water injection on the crushed mixed coal, feeding coking coal into a charging car for tamping, so that the coking coal is smashed into a dense coal cake, and feeding the coal into a carbonization chamber for performing high-temperature dry distillation; and d, performing high-temperature dry distillation on the coking coal, performing coke quenching by adopting a dry method, and finally naturally cooling to obtain the chemical coke product. According to the method, low-cost smelting and chemical industry carbon materials can be produced, and the gap that smelting and chemical industry carbon materials are deficient is overcome.

Description

technical field [0001] The invention relates to a coke oven coking method for increasing the proportion of long-flame coal used in chemical coke in the energy conversion and processing industry. Background technique [0002] Coking is an energy conversion processing industry, which is the process of converting coking into coke, coke oven gas, coal tar, crude oil and other products through dry distillation. Compared with coal deep processing forms such as coal-to-liquids and coal gasification, the coal coking mode is a mode with the simplest process, the highest energy conversion rate, the lowest cost and the most abundant related products in the form of coal deep processing. However, due to historical, technical, management, mechanism and other reasons, my country's coking industry has been in a state of high pollution, high energy consumption, and extensive for a long time, and while coke prices are falling, product quality requirements are getting higher and higher, facing...
