Thermal-state temping coking process

Abstract

A thermal-state stamping coking process is carried out by crushing coal, mixing with raw materials, entering it into bunker, delivering it to additive channel at one side of carbonizing chamber by conveyor, heating coal at 200-450degrees C, stamping the melt coal by stamping mechanism at top of carbonizing chamber, and stamping the coal into high-density coal cake. It has higher stamping strength, can improve M40 to 8-10% and decrease coke porosity.

Description

(1) Technical field:

[0001] The invention relates to a coking process, in particular to a hot stamping coking process. (2) Technical background:

[0002] The mixed coal is tamped into a coal cake with a volume slightly smaller than that of the carbonization chamber with a tamping machine before being put into the furnace, and then pushed into the carbonization chamber for coking, which is called tamping coking. Its characteristics are that it can increase bulk density, increase coke strength, and reduce porosity. The tamping process is completed before coking. In order to ensure the stability of briquettes, the aspect ratio of briquettes is generally less than 9:1. This limits the application of tamping coking in large coke ovens. (3) Contents of the invention:

[0003] The object of the present invention is to provide a thermal stamping coking process, which is not only simple in process, but also low in cost.

Examples

Embodiment 1

[0011] A thermal stamping coking process, characterized in that the coal is pulverized and mixed first, then enters the coal bunker, and then is sent to the feeding chute on the side of the carbonization chamber through a conveyor belt, and the coal in the carbonization chamber reaches 350-400°C At the same time, the coal in the reflow state is tamped by the tamping mechanism arranged on the top of the carbonization chamber, so that the coal is directly tamped into a dense coal cake in the carbonization chamber.

Embodiment 2

[0013] A thermal tamping coking process, characterized in that the coal is pulverized and mixed first, then enters the coal bunker, and then is sent to the feeding chute on the side of the carbonization chamber through a conveyor belt, and when the coal in the carbonization chamber reaches 380°C, The tamping mechanism installed on the top of the carbonization chamber tamps the coal in the reflow state, so that the coal is directly tamped into a dense briquette in the carbonization chamber.
