Exhausting, noise eliminating and cooling device and on-board micro gas turbine generator unit

Abstract

The invention discloses an exhausting, noise eliminating and cooling device and an on-board micro gas turbine generator unit, and relates to the technical field of gas turbine power generating equipment. The exhausting, noise eliminating and cooling device comprises a shell, a first micro hole layer, a first noise absorption layer and a plurality of partitioning noise absorption plates. An inner cavity of the first micro hole layer is divided into a plurality of cavity bodies by the partitioning noise absorption plates. The partitioning noise absorption plates located at the smoke input end retract toward the exhausting, noise eliminating and cooling device by a first distance. The smoke input end of the exhausting, noise eliminating and cooling device is connected with a smoke outlet of agas turbine. The smoke outlet stretches into an inner hole of the smoke input end by a second distance. An annular hole channel is formed between the outer surface of the smoke outlet and the inner surface of the smoke input end. The technical problems in the prior art that the temperature of the smoke exhausted by the on-board micro gas turbine generator unit is excessively high and exhausting noise is loud, and therefore thermal infrared characteristics are obvious and stealth function is poor in military are solved.

Description

Technical field [0001] The invention relates to the technical field of gas turbine power generation equipment, and specifically relates to an exhaust muffler and cooling device with low thermal infrared characteristics and low noise and a vehicle-mounted micro gas turbine generator set. Background technique [0002] There are three main types of traditional gas turbine exhaust gas cooling methods: using exhaust gas thermal energy to generate electricity, spray cooling technology, and absorption refrigeration devices. However, the above three types of technologies have shortcomings. Although the exhaust gas thermal energy power generation can reduce the exhaust temperature and realize the recovery and utilization of exhaust heat, the structure is complex, inconvenient to install, and the cost is high. The spray cooling technology is to install fine details on the exhaust end. The water mist evaporative cooler can significantly reduce the exhaust temperature, but the water use...
