According to the combustion condition of the gas in the combustion chamber, the opening and closing of the waste gas weight 4 and the air cover plate 3 of the waste gas shutter are selected. When the gas is combusted in the combustion chamber: the front piston rod 18 of the driving oil cylinder 5 is contracted (the rear piston rod 19 is extended), the air cover plate 3 of half of the whole furnace is controlled to be opened, and the waste gas weight 4 is controlled to be closed in a linkage manner; when the gas is burnt in the combustion chamber and waste gas is required to be discharged: the front piston rod 18 of the driving oil cylinder 5 extends (the rear piston rod 19 contracts), the waste gas weight 4 of half of the whole furnace is controlled to be opened, and the air cover plate 3 is controlled to be closed in a linkage mode. And finally, half of the regenerators 1 are used for air intake, and the other half of regenerators are used for air exhaust 1.
The interval time of the action of the driving oil cylinder 5 is 20-30 minutes. The air flow and the exhaust flow of the whole furnace are controlled to flow according to the heating requirement of the coke oven by the contraction and the extension of the driving oil cylinder 5, so that the requirement of gas flow between adjacent vertical flame paths is met, namely, the automatic timing reversing of the ascending gas flow and the descending gas flow according to the gas flow direction of 20-30 minutes is met.

The method for exchanging and driving the exhaust gas air in a linkage manner is characterized in that: the interlocking switching waste gas and air exchange transmission device is adopted, and the action of a driving oil cylinder is controlled, so that the driving oil cylinder drives a waste gas pull rod and an air pull rod to swing back and forth in the horizontal direction through a transmission chain; when the waste gas pull rod swings, the waste gas roller is driven to rotate, and two ends of any waste gas chain respectively ascend and descend, so that one of two adjacent waste gas weights is opened, and the other one of the two adjacent waste gas weights is closed; when the air pull rod swings, the air roller is driven to rotate, and two ends of any air chain respectively ascend and descend, so that one of two adjacent air cover plates is opened, and the other air cover plate is closed; in the same regenerator, the opening states of the waste gas weight and the air cover plate are opposite.
7. The interlocking switchable exhaust air exchange transmission method of claim 6, wherein: the interval time of the action of the driving oil cylinder is 20-30 minutes.
