<p>PURPOSE:To obtain an exhaust gas filter regenerator which prevent a generation of low temperature distribution part owing to the air cooling at the center of a filter, and to keep the temperature of the whole body of the filter adequately, in a regeneration time of the exhaust gas filter whose center is made in a hollow. CONSTITUTION:In this exhaust gas filter regenerator, a front side electric heater 3 is installed to the exhaust gas entrance side of an exhaust gas filter 1 whose center is made in a hollow, a peripheral electric heater 4 and an adiabator 10 are installed to the outer periphery of the filter 1, and furthermore, a central electric heater is inserted to the hollow 5 of the filter 1. The central electric heater is divided into at least two or more parts in the flowing direction of the exhaust gas, and the central electric heaters 6, 7, and 8 are operated by a converting means of output switches.</p> |
