Embodiment 1
[0021] like figure 1 As shown, in the subsequent treatment process of joint coke carbonization reaction, the needle coke raw material enters the coke tower to undergo cracking and condensation reactions after being heated by heat exchange and coking heating furnace, and then cracks to generate needle coke green coke through exothermic and endothermic cracking , the gas blowing conditions after the coke tower reaction are divided into three stages:
[0022] The first stage: first use high-temperature and high-pressure steam to blow air. The high-temperature and high-pressure steam is 2.5MPa and 450°C to maintain the coke formation reaction in the tower;
[0023] The second stage: using medium and low pressure steam, the steam condition is 1.3MPa, 280°C, and continue to purge the incompletely reacted oil and gas;
[0024] The third stage: a large amount of low-pressure steam purging, the steam condition is 0.3MPa, 180 ℃.
[0025] After the blowing condition is completed, water...
Embodiment 2
[0027] like figure 1 As shown, in the subsequent treatment process of joint coke carbonization reaction, the needle coke raw material enters the coke tower to undergo cracking and condensation reactions after being heated by heat exchange and coking heating furnace, and then cracks to generate needle coke green coke through exothermic and endothermic cracking , the gas blowing conditions after the coke tower reaction are divided into three stages:
[0028] The first stage: first use high-temperature and high-pressure steam to blow air. The high-temperature and high-pressure steam is 3.0MPa and 480°C to maintain the coke formation reaction in the tower;
[0029] The second stage: use medium and low pressure steam, the steam condition is 1.5MPa, 300℃, and continue to purge the incompletely reacted oil and gas;
[0030] The third stage: a large amount of low-pressure steam purging, the steam condition is 0.4MPa, 200 ℃.
[0031] After the blowing condition is completed, water is...
Embodiment 3
[0033] like figure 1 As shown, in the subsequent treatment process of joint coke carbonization reaction, the needle coke raw material enters the coke tower to undergo cracking and condensation reactions after being heated by heat exchange and coking heating furnace, and then cracks to generate needle coke green coke through exothermic and endothermic cracking , the gas blowing conditions after the coke tower reaction are divided into three stages:
[0034] The first stage: first use high-temperature and high-pressure steam to blow air, the high-temperature and high-pressure steam is 3.5MPa, 500°C, and maintains the coke formation reaction in the tower;
[0035] The second stage: use medium and low pressure steam, the steam condition is 1.8MPa, 350℃, and continue to purge the incompletely reacted oil and gas;
[0036] The third stage: a large amount of low-pressure steam is purged, and the steam condition is 0.5MPa, 230°C.
[0037] After the blowing condition is completed, wa...
