The lower end of front head 12 is equipped with cooling water inlet 5, and the upper end is equipped with cooling water outlet 6, after cooling water enters the water inlet pipe box, carries out heat exchange with coke oven gas through cooling water pipe bundle 3, and then is discharged to the cooling water pool and is cooled through the backwater pipe box. Cylinder 2 is also equipped with several cooling water pipe bundles 3. The lower side of the front flange of cylinder 2 is fixedly provided with a gas inlet 1 close to the front flange, and the gas inlet 1 is in communication with the inside of the cylinder 2. The lower part of the rear flange of the cylinder 2 is fixedly provided with a gas outlet 4 close to the rear flange. The gas goes through the shell, is cooled by the cooling water pipe bundle, and is then delivered to the use position. The inside of the rear head 13 is provided with a movable inner head 15, so that the pipe box composed of the cooling water pipe bundle 3 can expand and contract with the temperature change to cope with the problem of stress concentration of the cooling pipe bundle caused by large temperature change of the gas.
