High efficiency diesel generator set

By installing a cooling device and an exhaust waste heat recovery device in the diesel generator set, the cooling intensity and heat dissipation demand can be dynamically adjusted. The waste heat of the exhaust gas is used to preheat the intake air, which solves the problem of low waste heat utilization efficiency and achieves high-efficiency cooling and combustion efficiency improvement.

Abstract

This invention provides a high-efficiency diesel generator set, including a generator and an engine, which are coaxially connected. A water tank is located next to the engine, and a main shaft is located at the engine output end. The engine includes a cylinder block and a fuel tank. The main shaft extends into the cylinder block. A cooling device is provided between the engine and the water tank, and the cooling device is connected to the main shaft via a belt drive. An air filter is located on one side of the engine, and a delivery pipe is provided on the air filter. An interchange pipe is connected to the delivery pipe, and the end of the interchange pipe is connected to a main turbocharger. The end of the main turbocharger is provided with a split pipe that connects to the cylinder block. A main circulation pipe is located on one side of the water tank, which consists of an inlet pipe, an inner circulation pipe, an outer circulation pipe, and a first return pipe connected in series. A control console is located on the top of the engine, and an exhaust waste heat recovery device is located on one side of the cylinder block. Based on the water temperature and cylinder block temperature, the clutch can automatically engage or disengage according to the real-time engine load to precisely control the fan speed.
