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:
The present invention relates to a kind of coke making process, be specially a kind of thermal-state temping coking process.
(2) technical background:
Mixed coal is made firm by ramming into plug ramming machine after volume is slightly less than the briquette of carbonization chamber going into the stokehold, push the indoor coking of carbonization and claim tamping coking.Be characterized in improving bulk density, increase coke intensity, reduce void content, it is made process firm by ramming and finishes before coking, and in order to guarantee the stability of briquette, the depth-width ratio of briquette generally all less than 9: 1, has limited the application of tamping coking on capacity coke oven.
(3) summary of the invention:
The object of the present invention is to provide a kind of thermal-state temping coking process, this technology not only technology is simple, and cost is low.
The technical scheme that adopts is:
A kind of thermal-state temping coking process, it is characterized in that earlier with coal through pulverize, behind the batch mixing, enter coal bunker, deliver to the material loading chute of carbonization chamber one side then through travelling belt, when the coal for the treatment of the carbonization chamber reaches 200-450 ℃, coal is in the soft heat state, by the tamping agency that is arranged on top, carbonization chamber the coal of soft heat state is made firm by ramming then, makes coal at the indoor bigger briquette of density of directly making firm by ramming into of carbonization.
Processing unit of the present invention is at the top, carbonization chamber of body of heater tamping agency to be installed, this tamping agency comprises hydro-cylinder or mechanical cylinder bar and the refractory materials pressure head of depressing the lifting mechanism drive, hydro-cylinder or machinery are depressed lifting mechanism, and to be arranged on carbonization outdoor, the cylinder bar passes bell, and it is indoor to stretch into carbonization, the refractory materials pressure head is fixed on the lower end of cylinder bar, and depresses lifting mechanism by hydraulic cylinder type machinery and drive and back and forth to press down, and the coal dust that carbonization is indoor is pressed into the high-density briquette.
The indoor best coal temperature scope of making firm by ramming of above-mentioned carbonization is 350-400 ℃.
The present invention compared with prior art, thoroughly changed the outer ramming coke making process of conventional oven, employing is in the carbonizing chamber of coke oven retort process, be that the carbonization chambers temp is when 400 ℃ of left and right sides, coal is in soft melting and carries out tamping coking under the state, has improved greatly and has made intensity firm by ramming, and M40 can improve 8-10%, non-coking coal proportioning is increased, reduced the void content of coke.
(4) description of drawings
Fig. 1 is a process flow sheet of the present invention.
(5) embodiment:
