Description of drawings:

Further specify the utility model below in conjunction with the drawings and specific embodiments.

Fig. 1 is the utility model structural representation

Embodiment:

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

The utility model is at existing the big shortcoming of energy loss in the diesel generating set running, and adopts a kind of efficient power generation unit shown in Figure 1.

With reference to Fig. 1, this figure is shown as a kind of efficient power generation unit that adopts the utility model design, mainly comprise, muffler system 1, solar heat-collection plate 2, steam air-conditioning 3, middle cold and warm exchanger 4, water pump 5, water tank 6, DSP control system 7, generator 8, waste gas recovering device 9, the water jacket water heat source exchanger, the water jacket gas-heat exchanger, the water jacket water heat source exchanger is located on the cooling circuit of machine oil cooler, utilize hot water and water tank 6 interior water in the diesel generating set cooling circuit to carry out heat exchange, the water jacket gas-heat exchanger is located on the diesel generating set exhaust loop, utilize high temperature energy and the water tank 6 interior water contained in the diesel generating set waste gas to carry out the heat exchange second time, in this cover circulatory system, not only utilized the generator preheating, reduce diesel generating set inner engine oil cooling water temperature simultaneously, improve the diesel generation engine efficiency.

DSP control system 7 is the core control section of diesel generator system, be located in the diesel-generator set control case, and water pump 5 systems are located on the motor, water pump 5 is by 7 controls of DSP control system, by the real-time detection to each unit temp, the control frequency variator drives water pump 5 systems, thus heat exchange water flow in the control heat exchanger 4, make the water of control system heat exchange keep constant temperature, drive steam air-conditioning 3 by these heats again and reach the purpose that heats or freeze.Popular in the market diesel generator control module function (starting that DSP control system that the utility model uses 7 is not only integrated; operation; protection and parallel operation etc.), the control protection (collection of temperature, the control of water pump system etc.) of also having disposed a whole set of control system.
