摘要： The temperatures of exhaust gas streams into a black smoke eliminating device are uniformly raised to assuredly burn and eliminate the black smoke at the black smoke eliminating device. Accordingly, the restoration of the black smoke eliminating device is uniformly carried out while avoiding melt damage of the filter.Further, the exit temperature of the black smoke eliminating device is descended by a simple device of lower cost.For accomplishment of the present objects, the heating device and black smoke eliminating device are provided in a plural and divided manner and there are provided a baffle member and a space portion, to thereby equalize the volume quantities and temperatures of exhaust gas flows flowing into these devices.Further, the fuel is atomized into fine particles by injection into pressurized air and the obtained mixture is uniformly mixed into the exhaust gas, so that there are uniformly raised the temperatures of exhaust gas streams into the black smoke eliminating device.The temperature of exhaust gas is descended by a simple structure of porous body disposed downstream of the black smoke eliminating device.

摘要翻译： 排入黑烟消除装置的排气的温度均匀地升高，以确保在黑烟消除装置上燃烧和消除黑烟。 因此，黑烟消除装置的恢复被均匀地进行，同时避免了过滤器的熔体损坏。 此外，黑烟消除装置的出口温度由较低成本的简单装置下降。 为了实现本发明的目的，加热装置和黑烟消除装置以多个分开的方式设置，并且设置有挡板构件和空间部分，从而使流入这些的排气流的体积量和温度相等 设备。 此外，通过注入加压空气将燃料雾化成细颗粒，并将所得混合物均匀地混合到排气中，从而均匀地将废气流的温度升高到黑烟消除装置中。 废气的温度由设置在黑烟消除装置下游的多孔体的简单结构而下降。
