In the prior art, what Measures on Noise Control adopted is the first or the third, and from sound source control noises, be exactly consider to reduce noise, the noise source of gas turbine from gas turbine itself, being be difficult to realization, is also impossible.And the third, take protective measures at acceptance point, this is the protective measures of individual, as cotton in earplug, anti-sound etc., although this is a kind of economic and effective method, the measure of just a kind of passiveness, can not the basic pollution solving noise.
Model utility content
Be difficult to realize, can not fundamentally solve the deficiencies such as the pollution of noise for Measures on Noise Control in prior art, the technical problems to be solved in the utility model is to provide a kind of high temperature, high-speed fuel gas of complete for gas turbine unit combustion engine being discharged and introduces air and guarantee the complete unit exhaust silencer of gas turbine that staff and surrounding environment are not subject to exhaust sound and pollute.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The complete unit exhaust silencer of the utility model gas turbine, be installed in the exhaust passage of gas turbine, for dissipative muffler, adopt multichannel strip-type silencer structure, the formation exhaust passage, space namely between the adjacent strip-type silencer of multiple strip-type silencers be arranged in parallel.
Dissipative muffler has independently casing, and multiple strip-type silencer integral installation be arranged in parallel is in casing, and cabinet wall is provided with thermal insulation layer.
Multiple strip-type silencer be arranged in parallel is all installed in casing with board plug structure form.
Strip-type silencer has tower structure, and the both sides that framework is corresponding are fixed by the distribution form of regulation by the fastening piece connecting microperforated panel, are quieter material layer between the microperforated panel of both sides.
Be thermal insulation layer between the both sides microperforated panel of strip-type silencer and quieter material layer.
Strip-type silencer one end is for meeting air-flow end, and this is met air-flow end and is provided with semicircle guide plate.
The framework of strip-type silencer adopts plug-in type to connect in casing.
The utility model has following beneficial effect and advantage:
1. the utility model is arranged in the exhaust passage of gas turbine, has both allowed air-flow to pass through and can decay or hinder sound transmission, in wider frequency range, having had higher acoustic absorptivity; Humidity resistance is good, material free from extraneous odour, does not affect the health of people;
2. the utility model does not corrode Structural Hardware, easily manufactures and processing; Nonflammable, performance is steady in a long-term, and not easily aged deterioration, practicability is very strong.
3. the utility model can be widely used in the vent systems of the complete unit of gas turbine, and practicability is very strong.

Embodiment
Below in conjunction with Figure of description, the present invention is further elaborated.
What the present invention adopted is take control measure in noise transmission approach, and concrete dissipative muffler and the microperforated panel of adopting combines, and meets gas turbine noise standard regulation.
Dissipative muffler is the sound absorption utilizing sound-absorbing material, makes the device that the noise along channels spread is constantly decayed gradually by absorbing.Sound-absorbing material is fixed on air-flow by passage perisporium or line up in the channel by certain way, just forms dissipative muffler.When sound source enters in silencing apparatus, just cause the air fibres in dissipative muffler in porous material to vibrate, lose because surface friction drag and viscous resistance make a part of acoustic energy be converted into heat energy, just play noise elimination effect.
The complete unit exhaust silencer of the utility model gas turbine is installed in the exhaust passage of gas turbine, for dissipative muffler, adopt multichannel strip-type silencer structure, the formation exhaust passage, space namely between the adjacent strip-type silencer of multiple strip-type silencers be arranged in parallel.
As shown in Figure 1, 2, dissipative muffler has casing 1, and multiple strip-type silencer 5 be arranged in parallel is all installed in casing 4 with plate form.Casing 1 inwall is provided with cabinet insulation layer 1.
Strip-type silencer 5 will have enough Rigidity and strengths, and strip-type silencer 5 sound-absorbing material must be fixed up with firmly pavement structure.As shown in Figure 3,4, strip-type silencer 5 has framework, and gimbal axis is fixedly connected with microperforated panel 7 to both sides, is quieter material layer 8 between both sides microperforated panel 7, is thermal insulation layer 9 between microperforated panel 7 and quieter material layer 8; The framework of strip-type silencer 5 adopts plug-in installation to be connected with casing at dissipative muffler.
Cabinet insulation layer 1 outside is outer casing, and cabinet insulation layer 1 inboard is also provided with internal protective plate, by pressing plate, cabinet insulation layer and internal protective plate is coupled together.Internal protective plate adopts heat-resistant material, is designed to inflatable structure.Bolt is welded in the outer casing of casing 1 by distribution situation.Because combustion turbine exhaustion temperature is high, flow velocity is large, thermal insulating material is rock cotton board, insulation layer thickness can be chosen according to calculating, each bloop is welded into framework by heat-resisting alloy steel, centre is sound absorbing material alumina silicate fiber felt, microperforated panel is posted on both sides, and semicircle is made in the one end of meeting air-flow, to reduce flow resistance loss.
Combustion turbine exhaustion noise generally belongs to the noise of medium, high frequency scope, can select dissipative muffler.Because blast tube size is comparatively large, be thus designed to multichannel chip dissipative muffler.Combustion turbine exhaustion muffler desing becomes N sheet (the present embodiment is 4), chip dissipative muffler (as shown in Figure 3,4).For chip dissipative muffler, be in fact several parallel rectangular channels.Chip dissipative muffler is owing to being divided into several small channels general passage, and each small channel sectional area is little, will improve upper limit failure frequency, turn increases sound-absorbing material surface area simultaneously, then sound deadening capacity also can correspondingly increase.
The utility model is according to the length of the requirement determination silencing apparatus of sound deadening capacity.Because the sound deadening capacity of dissipative muffler is directly proportional to the length of silencing apparatus, after blast tube cross section is determined, increase silencing apparatus length and can improve sound deadening capacity.
