Acoustic hood of distributed energy gas generator set for utilizing afterheat to improve generating efficiency

The invention provides an acoustic hood of a distributed energy gas generator set for utilizing afterheat to improve generating efficiency. The acoustic hood comprise an energy input block, an electrical power system block, a combined energy producing block, an electrical energy output block and an afterheat energy reproduction block. The acoustic hood is characterized in that a combustion-supporting air processor module is additionally arranged on an air inlet channel, an air passage of the combustion-supporting air processor module is connected with a cold source of a refrigerating unit in the combined energy producing block in a sealed heat exchanging way, and the capacities of the refrigerating unit and a combustion-supporting air processor are configured in a balancing way. According to the acoustic hood, under the premise of meeting the noise pollution treatment effect of a machine room, the operating environment of the gas generator set is guaranteed, so that the operating conditions of the gas generator set approach to or are superior to product ex-factory test conditions required by a manufacturer, and external conditions are provided for improving stable operation factors of equipment.
