Embodiment Construction
[0027] Such as figure 1 As shown, 1 is the turbine outlet, 2 is the tailpipe, 3 is the sprayed water mist, 4 is the water mist nozzle, and 5 is the end valve.
[0028] The present invention has two working modes:
[0029] 1. The water mist nozzle always works with the engine body and consumes a lot of water. When the high-temperature exhaust gas fills the entire tailpipe, the end valve is closed, water mist is sprayed, the pressure of the tailpipe drops significantly, the turbine accelerates, and the temperature of the exhaust gas flowing out of the turbine decreases relatively. When the gas in the tailpipe basically turns into low-temperature exhaust gas, the end valve opens, and the high-temperature exhaust gas squeezes out the low-temperature exhaust gas to start the next working cycle.
[0030] 2. The water mist nozzle only works when the turbine needs to be accelerated. When the turbine is running in a steady state, the sprayer does not work, saving water. Alternativel...
