The utility model discloses a set up annular through groove on the body, establish the connecting plate of making by plastic material at the annular through groove inside callipers, can effectually reduce the excessive phenomenon of body thermal stress, and then avoid the body to crack.
Description
Technical field
This utility model relates to gas turbine auxiliary equipment field, in particular it relates to a kind of discharge duct avoiding tube wall to produce crack.
Background technology
Gas turbine is with the gas flowed continuously for working medium impeller high speed rotating, by the internal combustion type dynamic power machine that the energy conversion of fuel is useful work, is a kind of rotary vane type Thermal Motor.Gas turbine, as a kind of high efficiency internal combustion engine, is applied more and more extensive.
Gas turbine can produce substantial amounts of waste gas in the course of the work, and the waste gas of generation carries out filtration treatment to waste gas in needing to be input to flue gas processing device by conveyance conduit, it is to avoid enters waste gas and is directly discharged in air pollution environment.
In the front end of defecator, conveyance conduit is set, on the one hand it is transported to defecator for produced by gas turbine, on the other hand the EGT produced due to gas turbine is higher, gas pipeline can play heating power cushioning effect, it is to avoid the too high waste gas of temperature enters directly into defecator affects the use of defecator.
Existing conveyance conduit has bigger thermal stress, is easily generated crackle.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of discharge duct avoiding tube wall to produce crack, with the problem overcoming existing gas pipeline to be easily generated crackle.
The technical scheme in the invention for solving the above technical problem is: avoid tube wall to produce the discharge duct in crack, including body, it is provided with annular through groove on the ring wall of described body, two end symmetric of annular through groove are provided with 2 grooves, the bottom of groove is provided with spring, the end of spring is provided with grip block, and connecting plate is fastened in annular through groove by 2 grip blocks, and described connecting plate uses plastic material to make.
Owing to the aerofluxus of gas turbine has bigger heat energy, existing pipeline has bigger people's stress in conveying exhaust process, causes pipeline to crack, and impact uses.
Two ends of annular through groove described in the utility model specifically refer to annular through groove in body 2 ends radially, annular through groove is just blocked by described connecting plate, described plastic material is a kind of prior art material, there is certain plasticity, when body expanded by heating, owing to plastic material has certain plasticity, it is possible to the phenomenon that effective reduction body thermal stress is excessive, and then body is avoided to crack.
This utility model is by arranging annular through groove on body, and in annular through groove, card sets the connecting plate being made up of plastic material, it is possible to the phenomenon that effective reduction body thermal stress is excessive, and then avoids body to crack.
Further, the outer wall of body is provided with heat-insulation layer.
The setting of heat-insulation layer avoids the heat in body to radiate, and reduces the heat radiation of body.
Further, protective layer uses polythene material to make.
Polythene material is prior art material, has the effect of insulation.
Further, heat-insulation layer is set in tube wall by slide fastener or double buckle.
Further, the outer wall of body is set to flank.
Flank can effectively increase the frictional force of body and heat-insulation layer so that heat-insulation layer is firmly set in tube wall.
Further, plastic material is politef.
Politef is prior art material, can not only meet plasticity requirements, and the advantage with corrosion-resistant and high-temperature resistant.
Further, the end of grip block is provided with draw-in groove, and the end of connecting plate is provided with and the projection of card slot fit.
Improve, with protruding coordinating, the structural stability that connecting plate coordinates with grip block by draw-in groove.
Further, annular through groove is at least provided with 1.
Depending on the number that annular through groove is arranged can be according to actual body size.
To sum up, the beneficial effects of the utility model are:
This utility model is by arranging annular through groove on body, and in annular through groove, card sets the connecting plate being made up of plastic material, it is possible to the phenomenon that effective reduction body thermal stress is excessive, and then avoids body to crack.
