Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings and examples.

Referring to fig. 1 to 5, the micro housing of the present invention comprises: the internal combustion engine comprises an internal combustion engine box body 1, an internal combustion engine chassis 2, an internal combustion engine air inlet shutter 3, an internal combustion engine air inlet filter 4, an internal combustion engine air inlet silencer 5, an ejector 6 and a soundproof door 7, wherein the internal combustion engine box body 1 has the main function of isolating noise, and the external noise of a housing meets the use requirement when an engine operates. The main function of the gas turbine chassis 2 is to ensure the integral strength, and the gas turbine chassis can be integrally hoisted during hoisting. The air inlet shutter 3 of the combustion engine mainly has the function of preventing rainwater from entering. The air inlet filter 4 of the gas turbine mainly has the function of ensuring that gas required by combustion of the gas turbine meets the requirement of cleanliness. The air inlet silencer 5 of the combustion engine mainly has the function of reducing the noise of an air inlet. The ejector 6 has the main function of exhausting high-temperature gas and exhausting air in the box body at the same time, so that the air in the box body flows circularly. The soundproof door 7 is mainly used for maintenance and repair of the engine.

Referring to fig. 6 to 7, the ejector 6 of the present invention is composed of an ejector upper assembly 8, an ejector lower assembly 9, and an exhaust funnel 10. Ejector upper portion subassembly 8 mainly include: an upper assembly outer plate 11, an upper assembly orifice plate 12 and an upper assembly sound absorbing material 13. The upper component outer plate 11 mainly functions as a lower injection system supporting plate to play a role in fixing and reinforcing. The upper assembly micro-perforated plate 12 functions primarily to dampen sound and reduce noise. The main function of the upper assembly sound absorption material 13 is sound absorption and sound insulation.

Exhaust draw and penetrate system lower part subassembly 9, mainly include: a lower assembly outer plate 14, a lower assembly orifice plate 15, and a lower assembly sound absorbing material 16. The upper component outer plate 14 mainly functions as a lower injection system support plate to play a role in fixing and reinforcing. The upper assembly micro-perforated plate 15 mainly functions to eliminate noise. The upper assembly sound absorbing material 16 serves the primary function of sound absorption and sound isolation.

The engine exhaust funnel is connected with the exhaust funnel of the ejector, and the main effect is that when high-temperature gas is exhausted, the ejector drives normal-temperature green gas in the housing to be exhausted, so that air in the housing flows, the gas in the box body can form a flowing state, and the exhaust ejector system is an exhaust ejector system and can play the roles of an exhaust system and a fan. The hot air in the box body can be ejected and discharged without using an independent air exhaust system with a fan, the same function as the air exhaust system is achieved, the temperature in the box body is reduced, and the temperature in the box body is controlled within a reasonable range. The upper component 8 of the ejector mainly has the function of noise elimination, and can be conveniently disassembled, so that the inspection is very convenient. Can produce very big noise when high-speed air current discharges, add sound absorbing material through inside and play the effect of sound absorption, the inner wall is laid the micropunch plate and can be reduced the impact of air current to sound absorbing material, can play fine noise elimination effect simultaneously.

When the ejector is designed, mainly the ejection parameters and the ejection distance are difficult to determine, and the proper parameters can be determined through repeated tests and multiple tests, so that the miniature gas turbine housing with the ejector is not widely applied. The ejector is less applied to the cover of the micro gas turbine. It is also contemplated that more advanced technology and well-established concepts may serve the same purpose or be substituted.

Although the present invention has been described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the present invention.
