Abstract
A cylindrical heating unit of an exhaust gas processing device is installed in a reactor. The cylindrical heating unit is provided with an exhaust gas introduction port provided in an insertion base part and a heated exhaust gas outlet provided at insertion end. The cylindrical heating unit includes a hollow cylinder, insulators, electric heaters, and holding members. The hollow cylinder has a double structure with an inner cylinder and an outer cylinder made of metal. A plurality of the insulators surround the inner cylinder and are provided at intervals from each other in a heater installation space between the inner cylinder and the outer cylinder. Electric heaters are mounted to the insulators. The holding members are attached to one of the inner cylinder and the outer cylinder or both and hold the insulators in the heater installation space.
