Model utility content
Technical problem to be solved in the utility model is, overcome the shortcoming of prior art, a kind of gas turbine case is provided, this product not only absorbs noise when combustion engine and auxiliary system operation thereof, make noise reduction in machine room and outdoor, lower the temperature simultaneously, heat insulation, explosion-proof, this product noise reduction value is not less than 60 decibels, heat insulation and heat control is not less than 130 degree, and the used heat distributed by gas turbine by forced ventilation system and the inflammable gas that may leak are discharged to outside factory building.
In order to solve above technical problem, the utility model provides a kind of gas turbine case, comprise waste heat outlet pipe, sound insulation casing, ventilation system, entering house door, suction port and vertical ladder, sound insulation casing is closed cube-shaped structure, waste heat outlet pipe is located at above sound insulation casing, ventilation system is arranged at sound insulation casing rear, entering house door is located on the sidewall of sound insulation casing dead ahead, suction port and vertical ladder are located on the sidewall of sound insulation casing, the top of sound casing is also provided with spare exhaust pipe, bypass duct and gas compressor outlet pipe, the spare exhaust pipe conducting external world and sound insulation box house, it is provided with switch sluice gate with sound insulation casing joint, bypass duct and gas compressor outlet pipe are connected other two outlets of the three-way baffle plate that the turbine engine in sound insulation casing connects respectively.
The technological scheme that the utility model limits further is:
Aforementioned ventilation system is cube-shaped structure, and ventilation system upper surface establishes ventilated port, and ventilated port arranges blinds baffle plate, and its inside is provided with blower fan; Waste heat outlet pipe, bypass duct, waste heat outlet pipe and gas compressor outlet pipe are steel pipe or Coating Steel Pipe; The bottom of sound insulation casing both sides sidewall is located at by suction port, and suction port is the rectangular window be embedded on sidewall, is provided with filter screen outside rectangular window, connects admission line inside it; Sound insulation casing comprises: noise abatement cooling layer, aluminium alloy layer and anticorrosive coat, noise abatement cooling layer and anticorrosive coat are located at the two sides of aluminium alloy layer respectively.
The utility model devises waste heat outlet pipe and bypass duct, cigarette and waste hot gas will be given up by three-way baffle plate separately discharge, the harmful matter in waste gas can be processed so respectively, and reclaim the preheating of waste hot gas and put in recycling and go, prevent the pollution of the environment, contribute to environmental protection, focus on simultaneously and can increase work efficiency; Meanwhile, the ventilation system of the utility model product is separately located at outside sound insulation casing, and in ventilation system, arrange blinds baffle plate, prevents rubbish incidental to drop into damage blower fan, or blocks ventilated port.
The beneficial effects of the utility model are:
The used heat that the utility model product gives out when discharging combustion engine and auxiliary system operation, temperature in maintenance case is lower than limit value, simultaneously by directly the heat load of power house ventilation will can be reduced outside waste heat discharge to factory building, and dilute the inflammable gas that may leak by high Air-cleaning technique and avoid the danger of blasting; During work, the inflammable gas that may leak is transported to inflammable gas prober detectable range from source of leaks, improve the probability that inflammable gas is found, and by the noxious gas emission in case to outside factory building, negative pressure runs the explosion-proof capabilities enhancing factory building, when the blower fan oepration at full load of ventilation system, in case, peak suction value can be reached.
The utility model product is that combustion engine provides the multiple functional protectiveness case of a beautiful shape; absorb noise when combustion engine and auxiliary system operation thereof; make noise reduction in machine room and outdoor; simultaneously lower the temperature, heat insulation, explosion-proof; this product noise reduction value is not less than 60 decibels; heat insulation and heat control is not less than 130 degree, and the used heat distributed by gas turbine by forced ventilation system and the inflammable gas that may leak are discharged to outside factory building.
