Diesel generator with exhaust gas purifying function

The present invention relates to a diesel engine type generator having an exhaust gas purification function. A wet type purifier for filtering exhaust molecules inside the exhaust gas in a wet method is installed in the end of the exhaust pipe of the diesel engine type generator. A bypass pipe is installed between final exhaust pipes of the wet type purifier detachably installed in the upper plate, and having an exhaust fan and a middle part of the exhaust pipe of the diesel engine type generator connected to the inside of the wet type purifier. An overpressure safety valve is installed inside the bypass pipe. If the pressure inside the exhaust pipe exceeds a predetermined pressure, the overpressure safety valve is automatically opened, and exhaust gas, which was usually discharged from the diesel engine type generator by passing through the wet type purifier, is automatically discharged to the outside through the bypass pipe. Therefore, the present invention has an effect for preventing environment pollution sources, which are caused by exhaust gas discharged from the diesel engine type generator, in advance by completely purifying various exhaust molecules, which are included in exhaust gas of the diesel engine type generator operated in emergency such as a power failure, through the wet type purifier; and preventing in advance that the diesel engine type generator receives load by automatically discharging exhaust gas, which was discharged by passing through the wet type purifier, to the outside through the bypass pipe by automatically opening the overpressure safety valve if the back pressure, which is over the set pressure, is applied to the inside of the exhaust pipe since a dry type filter inside the wet type purifier is plugged due to long period usage.
