Problems solved by technology

The common disadvantages of the above three coal blending methods and their processes are that coke powder needs to be crushed in advance, which increases the investment in required equipment and sites, and the labor intensity of workers is high. Restricted, some iron and steel complexes mix coke powder into coal for use as fuel, or sell it at a low price

Embodiment Construction

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0012] The present invention relates to a coking method and process of coke powder back blending coal, which directly uses dedusted coke powder that does not need to be pulverized or ground as a thinning agent to replace clean coal and mix it with other coking coal evenly before entering the coking chamber of the coke oven for coking. .

[0013] Coke powder from CDQ environment dust removal, CDQ process dust removal coke powder, and coking ground dust removal station dust removal powder are collected and mixed uniformly in a ratio of 5:4:1, and then sent to the silo (1). 1) After the sealed belt conveyor (2) enters the batching trough (3) for processing, it is sent from the batching tray (4) to the conveyor (6) equipped with an electronic scale (5), and the batching rate is ≤5%. Quantitatively sent to the coal blending room pulverizer (9) on the belt con...

Abstract

This invention discloses a coal blending method and its technology of dust removal coking coal powder using as lean agent to substitute clean coal. It collects coke dry quenching environmental dust removal coking coal powder, coke dry quenching technological dust removal coking coal powder, coking ground dust moving station dust removal powder, mixing them homogeneously, and then putting them into stockhouse, and then transporting into dosage bunker by leather belt transport machine, and then transporting to leather belt transport machine equipped with electronic scale by dosage plate, and then quantitively transporting to leather belt transport machine equipped with dust fall equipment, and at last, sending into crusher together with other coal for coking and mixing them homogeneously in blending coal room for coking at coking chamber of coke oven.

Description

technical field [0001] The invention relates to a coking method and a process thereof, in particular to a coking method and a process for using dust-removed coke powder as a thinning agent instead of clean coal back to coal blending. Background technique [0002] Coking enterprises produce a large amount of coke powder in the production process. Due to its low price and polluting the environment, some coking enterprises crush coke powder and mix it back into coking coal instead of clean coal for coking. Certain economic benefits. However, due to the large water content of coke powder, generally between 8% and 15%, phenomena such as wall sticking and clogging may occur during the crushing process, which brings difficulties to the crushing process. The article "Equipment Selection of Coke Powder Remixing Process" published in the first issue of "Fuel and Chemical Industry" in 2005 discloses the commonly used coke powder crushing processing technology in the coke powder remixi...
