Description
Technical field
The utility model relates to Aero Engine Testing technical field, is a kind of exhaust gas heat recovery when the ground experiment for aero-engine and the device of noise reduction.
Background technology
Aero-engine ground experiment is indispensable working link in reseach of engine process. Aero-engine, in the time carrying out ground experiment, can produce the tail gas of a large amount of HTHPs, and exhaust temperature, up to 600 DEG C, attaches the noise of high-decibel simultaneously, and capacity can reach 20kg/s, contains huge energy. The conventional way of prior art is to be mixed and lower the temperature with tail gas by injection normal temperature air, then introduces after a silencing means noise reduction is processed and enters atmosphere, causes huge energy dissipation.
Utility model content
The purpose of this utility model is to provide a kind of aero-engine ground experiment exhaust gas heat and reclaims sound damping tower, can recycle also sound-deadening and noise-reducing to aero-engine heat of exhaust emissions when the ground experiment.
The technical scheme of utility model: aero-engine ground experiment exhaust gas heat reclaims sound damping tower, comprises exhaust injection cylinder, heat insulation tone chamber, exhaust tower, heat exchanger, silencing means. Heat insulation tone chamber is that a skin is the building that brick mix structure, internal layer are thermal and sound insulating materials, the building that exhaust tower is resistant to elevated temperatures brick mix structure, and heat insulation tone chamber is connected with exhaust tower. The resistant to elevated temperatures exhaust injection cylinder of being made up of metal material is communicated with exhaust tower through heat insulation tone chamber. The top of exhaust tower is provided with silencing means, and silencing means is made up of metal acoustical panel. The bottom of exhaust tower is provided with heat exchanger, and heat exchanger is made up of the metallic conduit with good thermal conductivity function.
Exhaust injection cylinder, for the high-temperature tail gas of engine and normal temperature air are mixed, enters mixed gas in exhaust tower simultaneously; Heat insulation tone chamber is used for sealing exhaust injection cylinder, by the noise spreading out of in exhaust injection cylinder and temperature isolation in this space; Exhaust tower plays the effect of heat-insulating sound-insulating, simultaneously by tail gas to high altitude discharge. Heat exchanger is used for absorbing high-temperature gas heat, realizes heat recovery function; Silencing means, for absorption test noise, is realized silencing function.
First high-temperature tail gas is introduced heat insulation tone chamber by exhaust injection cylinder, then passes through heat exchanger heat exchange. High-temperature tail gas passes through after heat exchanger, temperature and reducing noise, then after silencing means, enter atmosphere.
Advantage of the present utility model: can recycle the energy in aero-engine high-temperature tail gas, can play certain Noise Reduction, device is simple, small investment simultaneously.
