Retrofit of Dust Removal System for Coke Oven Ground Station


The dust removal system of the coke oven ground station was reformed. The coke oven ground dust removal station determined the "two-stage" plan for coal charging and coking to ensure that the coal loading flue gas did not enter the ground station and the coal loading raw gas was recycled. The new bag type dust collector will be used for coke guide dust removal. The existing top smoke and dust removal vehicle will be modified. The technology of introducing coal-laden flue gas into the carbonization chamber at the end of adjacent coking will be selected. The modified coal charging coke guiding system completely meets the dust removal requirements of tamping coke ovens. The dust removal system of the coke oven ground station is modified as follows:

1. Add paroxystic high-temperature flue gas cooling and separation flame arrester to coke oven ground dust removal station

In order to protect the bag and improve the safety of the coke oven dust removal system, before the flue gas discharged from the coke oven enters the ventilation slot and enters the dust collector, a sudden high temperature flue gas cooling and separation flame arrester is added to reduce the flue gas temperature and increase System protection function.


2. Modification of coke oven ground dust removal station hydraulic system of coke blocking vehicle

The large-diameter solenoid valve is used to configure the hydraulic station, which greatly increases the working speed of the hydraulic cylinder. In addition, a cooling cycle system outside the hydraulic station is added outside the hydraulic tank of the hydraulic station to reduce the operating temperature of the hydraulic station. component. For the phenomenon that the mechanical limit switch cannot touch the wall, the magnetic proximity switch is used as the limit, and the outdoor cable is fire-proofed. Due to different processes, the position of the hydraulic station is changed from the furnace roof to the third rail, and the outside is greatly reduced. Red coke bake on hydraulic station.


3. Pre-spraying of dust removal station on coke oven ground, transformation of ash ejection blowing system

After the transformation, the coal-fired flue gas will no longer enter, the ground station, the pre-injection system will lose its function, and the pre-injection system will have no problems. The pulse injection valve adopts imported products to increase the compressed air and diameter to improve the working stability of the injection equipment and the injection effect. The box double-layer ash discharge valve and solenoid valve are imported products, which work stably during trial operation. The original CaCO3 powder spraying was changed to coke-guided powder spraying, using dual-tube multi-point spraying. A new spraying pipe was added to the original spraying pipe. Relying on the high speed of the coke exit fan, the negative pressure generated was used to suck the coke powder into the coal. The ash hole under the dust removal bin is mixed with the coal ash powder, which increases the fluidity of the ash powder and is conducive to the reduction of ash. Through the actual operation, the effect is obvious. The ash deposit in the lower ash port is basically not included, and the ash is completely discharged. The scraper conveyor ensures the rapid discharge of combustible materials. Outside the warehouse, it is suppressed. The possibility of fire in the warehouse.


The ground station dust removal device is mainly composed of a dust collector body, a top pulse blowing device, a sonic dust removal device, a double-layer ash discharge valve and a thermal insulation heating device. Remove the dust on the inner wall surface of the bag and the silo. Add a steam-water heat exchange device to the dust removal bin and the outer surface to keep the heat treated. Use hot water to heat the dust removal bin to prevent the dust removal bin and high moisture content in the dust from burning. The water in the coal smoke is analyzed to prevent the hardening of the warehouse dust and improve the fluidity of the dust.

Application effect of coke oven ground dust removal station system reform


Transformation effect of coke oven ground station dust removal system:


1. The ground dedusting station system is used to remove dust, reduce the dust concentration in the coke oven production area, and purify the workers' production and operation environment. The coke oven dust removal meets the coking industry and national environmental protection emission standards.

2. After process improvement, the stability and safety of the system have been improved, and no accidents have occurred.

3. Because the operation control is simple and effective, the service life of the system equipment is extended, especially the service life of the bag. The system has been used for 18 months, and has not been replaced. The cloth bag has achieved the purpose of economic operation.

4. The successful application of the frequency conversion technology of this system not only saves power consumption, but also ensures that the suction of the main pipe of the system is stable and plays a key role in the safe and stable operation of the coke oven dust removal station system of the entire coking plant.
