Embodiment Construction
[0012] Below in conjunction with specific embodiment the present invention is described in further detail:
[0013] A kind of method that the present invention designs improves coke oven production efficiency, and it comprises the steps:
[0014] Step 1: Install a thermocouple in the raw gas rising pipe of each coke oven coking chamber (the purpose of setting the thermocouple is to measure the temperature of the raw gas. The raw gas at the pipe place is cooled by the sprayed ammonia water, and the temperature drops. Therefore, only at the riser can the temperature of the raw gas escape from the coke oven be measured), and the temperature of the raw gas in the coking process is measured by the thermocouple (the raw gas temperature Associated with the chemical reaction in the coking process, when the raw gas temperature reaches the maximum and then begins to drop, the coke cake polymerization reaction in the carbonization chamber will no longer precipitate gases containing tar a...

The invention discloses a method for improving production efficiency of a coke oven. The method comprises the steps that 1, thermocouples are arranged on all coke oven coal gas ascending pipes, the temperature of crude coal gas is measured by the thermocouples in the coking process, and a crude coal gas temperature signal is transmitted to a coke oven control center through the thermocouples in the coking process; step 2, the standard temperature of coking is set as 1200 DEG C-1350 DEG C, in the middle and later periods of coking, when the temperature of crude coal gas rises to the peak and isreduced by 20-40 DEG C, the coke oven control center controls a coke pusher to execute the coke pushing operation; step 3, a coke pot receives red coke and is put in a heating furnace, the heating furnace makes the temperature of coke stabilized at 900-1000 DEG C, the standing time of coke in the heating furnace is controlled to make the quality of coke meet the production requirements of a blastfurnace; step 4, after cooling and prilling of coke discharged from the heating furnace, the prilled coke is supplied to the blast furnace for using. The method can shorten turnover time of the cokeoven and improve the production efficiency of the coke oven.
Description
technical field [0001] The invention relates to the technical field of coking, in particular to a method for improving coke oven production efficiency. [0002] technical background [0003] The purpose of coking is to provide qualified coke for blast furnace ironmaking. The thermal system and coking time of the coking process are of great significance to control the quality of coke. The existing production method is to let the coke stay in the carbonization chamber for 2 to 3 hours after the fire falling phenomenon occurs in the coking process, so that the coke cake is completely polymerized and the cracks are fully formed, so that the quality of the coke can meet the needs of blast furnace production. Generally, the coking time of a 6-meter top-loading coke oven is about 20 hours, that of a 7-meter top-loading coke oven is about 22 hours, and that of a 7.63-meter top-loading coke oven is about 26 hours. If the proper coking time cannot be reached, the coke quality cannot b...
