The invention relates to a coal-charging and coke-discharging flue gas integration dust-removal process for a side coal-charging coke oven. A two-way connector valve is arranged on an oven column for the coke oven, the flue gas generated during the coal charging process of the coke oven and the flue gas generated during the coke discharging process of the coke oven enter in a common flue gas pipeline respectively through the two-way connector valve, and the dust removal is performed through a filtering type flue gas dust-removal device connected with the flue gas pipeline; the tar adsorption adopts a method that active powder adsorbent is sprayed in the flue gas pipeline, and the flue gas is discharged into atmosphere through a ventilator after being filtered and purified in a filtering type flue gas purification device; and the filtering type flue gas purification device performs off-line dust-cleaning regeneration after finishing coke discharging until the next coke discharging of the coke oven. No dust deposits in the process pipeline, the tar adsorption is complete, the dew point is not reached, the filter bag dust-cleaning regeneration is good, and the system is reliable and stable, thereby effectively ensuring the normal running of the coke oven with flue gas dust removal.
