Abstract
The utility model discloses a sealing structure for a rotary change valve of an organic waste gas heat storage oxidation furnace, which comprises a rotor and a stator. The rotor is in a frustum cone shape. A cavity in a frustum cone shape matched with the rotor is arranged on the stator. The rotor is provided with an asynchronous machine which drives the rotor to rotate and a stepping motor which raises and lowers the relative height of the rotor and the stator. The contact surface of the rotor and the stator is in a frustum cone shape, and the gap between the rotor and the stator can be adjusted through the stepping motor, thereby preventing the rotor from being clamped due to expansion caused by heating, simultaneously ensuring the smallest gap between the rotor and the stator, greatly reducing air flow between an air inlet area and an air outlet area of the rotary change valve, and improving treatment effects of a device.
