Abstract
The invention relates to coke producing technology field, concretely it is a method for producing coke by directly using loose asphalt. The coke production has certain requirement to the coal blending quality, because to make the quality of refined coke get to the industry standard, the quality of coal blending should be in certain bound. It also has limit to both weak cohesiveness and non-cohesiveness coals. The present coke producing craft is that add bitumen as molding coal into the coal blending, the craft of which is complex and cost reduction is limited. The technology project of the invention is: when there is weak cohesiveness or non-cohesiveness coal in the coal blending variety, add 15% weight of dispersed bitumen when blending. The invention realizes increasing the blending quantity of weak cohesiveness and non-cohesiveness coals. It can not only ensure the coke quality, but also reduce the producing cost.
Description
One, technical field:
The present invention relates to coke production technique field, specifically the technology of producing coke with the direct coal blending of bulk asphalt.
Two, background technology:
Coke production has certain requirement to used mixed coal quality, and mixed coal is in the certain quality scope, and the coke quality of producing just can reach industry standard.Single coal of planting of coke production has coking coal, rich coal, 1/3 coking coal, bottle coal, weak caking coal.Dosage for weak caking coal and dross coal is all restricted.Have now with pitch and make in the moulded coal adding mixed coal, be used for the technology of coke production.This technology is numerous and diverse, and cost reduces limited.
Three, summary of the invention:
The objective of the invention is to want to provide a kind of technology of producing coke, use the present invention can increase the dosage of weak caking coal and dross coal with the direct coal blending of bulk asphalt.
Technical scheme of the present invention: when weak caking coal or dross coal are arranged, allocate the bulk asphalt of weight≤15% when being mixed in the coal blending kind.The production technique of coke is identical with common process.
Technology of the present invention has increased the cohesiveness of mixed coal, has realized increasing the dosage of weak caking coal and dross coal.Bulk asphalt enters and produces coke in the pit kiln directly and after the coking coal cooperation.Through test, weak caking coal can be increased to about 30% by 5% of former proportioning, and dross coal can be increased to more than 10% by former proportioning 0.The present invention not only guarantees coke quality, and technology is simple, can reduce production costs significantly.Be to use pitch below and do not use the contrast of pitch implementation result:
Implementation result is not joined pitch and is joined the reduction of pitch ton cost
Cost contrast (unit/ton) 721 591 130 yuan
The quality product contrast:
Do not join pitch and join pitch

Embodiment 2: the coal blending weight percent is: rich coal 10,1/3 coking coal 17, coking coal 25, bottle coal 5, weak caking coal 30, bulk asphalt 13.
Embodiment 3: the coal blending weight percent is: rich coal 19,1/3 coking coal 17, coking coal 32, bottle coal 5, dross coal 3, weak caking coal 19, bulk asphalt 5.
Embodiment 4: the coal blending weight percent is: rich coal 10,1/3 coking coal 20, coking coal 24, bottle coal 5, dross coal 10, weak caking coal coal 18, bulk asphalt 13.
Claims (1)
1, a kind of technology of producing coke with the direct coal blending of bulk asphalt comprises that coking coal, rich coal, 1/3 coking coal, bottle coal are arranged in the coal blending kind, it is characterized by: when weak caking coal or dross coal are arranged, allocate the bulk asphalt of weight≤15% when being mixed in the coal blending kind.
