Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1:
referring to fig. 1, the present invention provides a technical solution: a system for ensuring negative pressure of a dry quenching discharging device comprises a chute 8, a rotary sealing valve 9 and a boiler 4, wherein an air suction pipeline A12 is arranged between the chute 8, the rotary sealing valve 9 and the boiler 4, the air suction pipeline A12 comprises an air suction pipe and a main pipe, the chute 8 and the rotary sealing valve 9 are both connected with the air suction pipe, the tail part of the boiler 4 is connected with the main pipe, the air suction pipe is communicated with the main pipe, the system comprises a dry quenching furnace 1, a vibration feeder 7, the chute 8 and the rotary sealing valve 9 are sequentially arranged at the bottom of the dry quenching furnace 1, a coke discharging chute and a coke discharging belt 10 are arranged below the rotary sealing valve 9, the system comprises a primary dust remover 2, the dry quenching furnace 1 is connected with the primary dust remover 2, the primary dust remover 2 is connected with the boiler 4, the tail part of the boiler 4 is connected with a secondary dust remover 3, the secondary dust remover 3 is connected with an inlet of a circulating fan 5, an outlet of the circulating fan 5 is connected with an inlet of an auxiliary coal economizer 6, the outlet of the auxiliary coal economizer 6 is connected with the dry quenching furnace 1, and the top of the vibration feeder 7 is provided with a flat gate 11.
When in implementation, the air suction pipeline A12 is only added on the basis of the original system: an air suction pipe is respectively led from the coke discharging and blanking point below the chute 8 and the rotary seal valve 9, and is combined into a main pipe before entering the tail part of the boiler, and then the main pipe is connected with the tail part of the boiler 4 (before the secondary dust remover 3).
The pressure at the tail part of the boiler 4 is-1.4 to-1.8 kPa, the pressure at the inlet of the dry quenching furnace is about 1.0kPa, and the pressure at the vibration feeder 7, the chute 8 and the rotary sealing valve 9 is about 0.6Kpa in consideration of coke resistance.
After the air suction pipeline A12 is communicated, the pressure at the vibration feeder 7, the chute 8 and the rotary sealing valve 9 is changed into negative pressure of-0.8 to-1.2 kPa, and the negative pressure is large enough to suck away carbon monoxide and dust at the vibration feeder 7, the chute 8 and the rotary sealing valve 9, and simultaneously, the residual sensible heat of coke at the discharging device is brought into the circulating fan 5 and enters the dry quenching furnace 1. During maintenance, the maintenance can be carried out only by closing the flat gate 11 and then waiting for about 4-5 minutes until carbon monoxide and dust at the vibration feeder 7, the chute 8 and the rotary sealing valve 9 are sucked away, and then the portable carbon monoxide alarm is used for detecting that no alarm is given at the vibration feeder 7, the chute 8 and the rotary sealing valve 9.
After the air suction pipeline A12 is communicated, the pressure of the coke discharging and blanking point below the rotary sealing valve 9 is close to the pressure of the tail part of the boiler, and dust at the position can be effectively sucked away. Because the coke discharging and blanking point below the rotary sealing valve 9 is communicated with the atmosphere, a part of air is sucked into the circulating system, and the oxygen content in the system is increased. Therefore, the air introducing valve at the middle bolt is properly closed, and the damage of air at the annular air channel to refractory materials is reduced. Meanwhile, high-oxygen-content circulating gas enters the dry quenching furnace from the inlet of the dry quenching furnace and gradually and completely reacts with coke powder in the dry quenching furnace in the rising process, the oxygen content is reduced to the minimum level when the circulating gas enters the annular air duct, so that the threat to refractory materials is hardly caused, and the heat generated by burning the coke powder makes up the heat deficiency caused by closing the middle bolt air inlet valve.
Example 2:
referring to fig. 2, the difference from embodiment 1 is: two sets of air suction pipes (an air suction pipe A12 and an air suction pipe B14) are added in the embodiment. An air suction pipe A12 is additionally arranged between the chute 8 and the tail part of the boiler 4 (in front of the secondary dust remover 3), and an air suction pipe B14 is additionally arranged between the air leading-in pipe 13 and the coke discharging and blanking point below the rotary sealing valve 9.
The pressure at the tail part of the boiler 4 is-1.4 to-1.8 kPa, the pressure at the inlet of the dry quenching furnace is about 1.0kPa, and the pressure of the vibration feeder 7 and the chute 8 is about 0.6Kpa in consideration of coke resistance. After the air suction pipeline A12 is communicated, the pressure of the vibration feeder 7 and the pressure of the chute 8 are changed into negative pressure of-0.8 to-1.2 kPa, the negative pressure is large enough to suck away carbon monoxide and dust of the vibration feeder 7 and the chute 8, and simultaneously, the residual sensible heat of coke at the discharging device is brought into the circulating fan and enters the dry quenching furnace, thereby not only ensuring the environmental protection effect, but also increasing the power generation benefit. During maintenance, the maintenance can be carried out only by closing the flat gate 11 and then waiting for about 4-5 minutes until carbon monoxide and dust at the vibration feeder 7, the chute 8 and the rotary sealing valve 9 are sucked away, and then the portable carbon monoxide alarm is used for detecting that no alarm is given at the vibration feeder 7, the chute 8 and the rotary sealing valve 9.
The pressure of the air leading-in pipeline is about-0.5 kPa, and after the air suction pipeline B14 is communicated, the pressure of a coke discharging blanking point below the rotary sealing valve 9 is close to the pressure of the air leading-in pipeline, so that dust at the position can be effectively sucked away. Because the coke discharging and blanking point below the rotary sealing valve 9 is communicated with the atmosphere, a part of air is sucked into the circulating system, and the oxygen content in the system is increased. Therefore, the air inlet valve on the air inlet pipeline is properly closed, the high-oxygen-content circulating gas is combusted with the coke powder sucked from the coke discharging and blanking point and the coke powder floating from the inclined chute to the annular air duct, the oxygen is completely consumed, and the increased heat makes up the insufficient heat caused by closing the air inlet valve; meanwhile, due to the consumption of oxygen, the damage of oxygen in the circulating gas to refractory materials such as silicon carbide and the like is avoided, and in addition, the environmental effect of a coke discharging and blanking point below the rotary sealing valve 9 can be effectively improved.
In conclusion, the system for ensuring the negative pressure of the coke dry quenching discharging device can effectively enable the vibration feeder, the chute, the rotary sealing valve and the coke discharging and blanking point to form the negative pressure by arranging a new air suction pipeline among the chute, the rotary sealing valve and the boiler, ensure that CO and dust at the vibration feeder, the chute and the rotary sealing valve are sucked away before maintenance, ensure the safety and the health of maintenance personnel, bring the residual sensible heat of coke at one part of the discharging device back to the coke dry quenching furnace for utilization, increase the steam yield of the boiler, increase the power generation benefit of a power station and the like.
