Abstract
The invention relates to a gas turbine package with fire protection, thermal insulation, ventilation and sound insulation functions. The gas turbine package comprises a box, a box wallboard, a ventilation system and a fire protection system. The box wallboard adopts a bilayer structure composed of a sound absorption layer and a sound insulation layer which both contain a partition board, the surface of which is sprayed with a material with a large sound loss coefficient. The insides of the sound absorption layer and the sound insulation layer are filled with thermal insulating glass silk floss. The ventilation system consists of a redundantly configured explosion-proof axial flow fan and an electrically driven inlet/outlet damper. The fire protection system includes extinguishing and discharge pipelines and nozzles, four flame detectors, a temperature detector, and four combustible gas detectors, wherein, the four flame detectors, the temperature detector, and the four combustible gas detectors are respectively installed on the inner walls of the box, and the nozzles are disposed on the extinguishing and discharge pipelines. The device provided in the invention can work stably under a round-the-clock condition, and make the inside and outside of the box in a safe environment so as to protect the safety of on-site maintenance personnel and guarantee the normal operation of a gas turbine.

Technical field
The invention belongs to the energy and field of dynamic engineering, be specifically related to a kind of gas turbine module with fire-fighting, heat insulation, ventilation and sound insulation function.
Background technique
Along with the continuous expansion of gas turbine as a kind of new type power application area on industry and naval vessel, the gas turbine module technology also grows up thereupon.Gas turbine is when the operation of high operating mode, and thermal exposure is very big around its body, and especially temperature is very high around high and low pressure turbine and the power turbine, and high energy is above 150 degrees centigrade; And noise is very big.This not only constitutes a serious threat to on-the-spot unit maintenance personnel's safety, also unit operation safety is constituted certain threat simultaneously.Therefore, designing a kind of safe and rational gas turbine module is very important.Case dress body must satisfy multiple functional requirements such as fire-fighting, heat insulation, ventilation, sound insulation.
Summary of the invention
The object of the invention provides a kind of gas turbine module with fire-fighting, heat insulation, ventilation and sound insulation function, with attendant's safety and the normal operation that ensures gas turbine of keeping the scene intact.
The objective of the invention is to realize like this: a kind of gas turbine module with fire-fighting, heat insulation, ventilation and sound insulation function; Comprise casing 16, wallboards of box body 15, ventilation system and fire-fighting system; Wallboards of box body 15 adopts absorbent treatment and Sound insulating layer double layer construction; Absorbent treatment and Sound insulating layer all include dividing plate; The surface of dividing plate is coated with the big damping material of sound dissipation coefficient; Be filled with the heat-protecting glass silk flosssilk wadding in absorbent treatment and the Sound insulating layer; Ventilation system by the explosion-proof type axial-flow blower of redundant configuration 1 with electrically drivenly advance/go out damper plate 2 to form; Fire-fighting system comprises that fire extinguishing blowdown piping 3 and shower nozzle 4, four flame detectors 5, hygrosensor 6 and 7, four flame detectors 5 of four combustible gas detectors, hygrosensor 6 and four combustible gas detectors 7 are installed in respectively on the cabinet wall, and shower nozzle 4 is installed on the fire extinguishing blowdown piping 3; At the other first double-colored audible-visual annunciator 8 and the first yellow audible-visual annunciator 9 of being equipped with of first combustible gas detector, casing top outer and an intake grill outer wall joint are equipped with first red audible-visual annunciator 10, second yellow audible-visual annunciator 11, second double-colored audible-visual annunciator the 12, the 3rd double-colored audible-visual annunciator 13 and a venting tutorial light 14.
Structure of the present invention can be under round-the-clock condition stable operation, make the environment that is in a safety inside and outside the casing, with attendant's safety and the normal operation that ensures gas turbine of keeping the scene intact.

Embodiment
Below in conjunction with accompanying drawing mode of execution of the present invention is further described in detail:
Wallboards of box body 15 adopts absorbent treatment and Sound insulating layer double layer construction; Absorbent treatment and Sound insulating layer all include dividing plate; The surface of dividing plate is coated with the big damping material of sound dissipation coefficient; Be filled with the heat-protecting glass silk flosssilk wadding in absorbent treatment and the Sound insulating layer; Ventilation system by the explosion-proof type axial-flow blower of redundant configuration 1 with electrically drivenly advance/go out damper plate 2 to form; Fire-fighting system comprises that fire extinguishing blowdown piping 3 and shower nozzle 4, four flame detectors 5, hygrosensor 6 and 7, four flame detectors 5 of four combustible gas detectors, hygrosensor 6 and four combustible gas detectors 7 are installed in respectively on the cabinet wall, and shower nozzle 4 is installed on the fire extinguishing blowdown piping 3; At the other first double-colored audible-visual annunciator 8 and the first yellow audible-visual annunciator 9 of being equipped with of first combustible gas detector, casing top outer and an intake grill outer wall joint are equipped with first red audible-visual annunciator 10, second yellow audible-visual annunciator 11, second double-colored audible-visual annunciator the 12, the 3rd double-colored audible-visual annunciator 13 and a venting tutorial light 14.After fire-fighting system is installed, to inflammable gas, flaming monitor, warning and unofficial biography, when breaking out of fire, accept outside extinguishing agent, and evenly be sprayed in the casing through flange-interface; During gas turbine operation, case dress body ventilation system combines the heat-insulating structure of wallboard to make the cabinet exterior surface temperature be no more than 60 degrees centigrade; During gas turbine operation, 1m place criteria for noise was measured less than 85 dB (A) (no background noise influence) around the sound absorption of case dress body inside panel and sound insulating structure can make casing.Four flame detectors and two hygrosensors of being installed in box house carry out fire detection, when flame or hygrosensor detect fire, send fire alarm signal, offer extraneous controller and handle.When having two probers to detect fire in flame detector and the hygrosensor simultaneously; Startup is installed in the inside and outside fire audible-visual annunciator of device and carries out the fire acoustooptic alarm; Close casing ventilation blower fan simultaneously, put the windscreen plate valve into, fire protection pipeline in the feeding of the extinguishing agent in the outside holding vessel casing is sprayed fire extinguishing into and out of air port and carbon dioxide gas speed.Detector can be selected the different manufacturers product for use, and that can be easily installed in correct position in the casing.Select condition for use: flame detector should have higher sensitivity, and its detection reaction time to flame answers≤5s.Flame detector should have good anti-wrong report property.During proper functioning,, should not cause the false alarm of flame detector owing to the infrared or ultraviolet that sunlight, thermal source, electric arc, lightning etc. are produced.When combustion machine combustion gas fuel, the concentration detection that the inflammable gas prober carries out inflammable gas is installed in casing, all detection information can offer external supervisory system and keep watch on and chain control processing.When detect the inner combustable gas concentration of device surpass low explosion limit 20% and 40% the time, this system should send the firsts and seconds warning message, supplies the control system to carry out corresponding warning, ventilation and shutdown processing.
