<p>PURPOSE:To eliminate the clogging of a particulate trap filter itself without generating breakage and melting and carry out the regeneration of the filter and the catching of particulates by one exhaust purifying device, by combusting the particulates caught by the particulate trap filter in a short time. CONSTITUTION:Each flow rate of the exhaust gas 13a and 13b is detected by a differential pressure sensor 8, and the combustion air quantity is adjusted by adjusting the exhaust gas quantity by varying the number of engine revolution, and the exhaust gas is allowed to pass successively through a plurality of rectifying plates 4a, together with the combustion gas 15 of a burner device 7, and the uniform mixed gas 20a is formed, and each temperature of the mixed gas 20a and 20b is detected by a temperature sensor 10. The temperature of the mixed gas is adjusted by varying the fuel supply quantity to the burner device 7, and the particulate which is piled on the filter surface of a particulate trap filter 2 is combusted by supplying a large quantity of the mixed gas 20a and 20b as the combustion air for the particulate.</p> |
