Abstract
Block omega type flexible coupling vortex baffle of flue gas leakage. The exhaust sealing plate always has the phenomenon of smoke leakage, which seriously damages thermal elements and has influenced the safe and stable operation of the unit. Meanwhile, due to over-temperature, the temperature in the air duct of the ventilation cooling fan of the exhaust section housing reaches over 100 ℃, and the motor bearing of the ventilation cooling fan (88 BD) runs at the over-temperature risk. The utility model discloses the constitution includes: this vortex baffle (3) are by two corrosion resistant plate (6) that distribute from top to bottom and fix two corrosion resistant plate between omega type flexible coupling (7) constitute, omega type flexible coupling enclose synthetic circular structure by two adjacent crisscross lapped a plurality of omega type flexible coupling boards of misplacing, omega type flexible coupling board be by a set of interval arrangement stainless steel sheet (8) and heat-resisting fiber cloth (9) the structure that the suppression formed. The utility model is used for block the flue gas and leak.
Description
The technical field is as follows:
the utility model relates to a gas turbine power generation technical field, concretely relates to block omega type flexible coupling vortex baffle of flue gas leakage.
Background art:
the original 9FB gas turbine exhaust diffusion section is in flexible connection with a gas turbine exhaust flue, three layers of sealing plates are formed, one layer is laminated, the inner ring of each sealing plate is connected with the corresponding exhaust diffusion section, the outer ring of each sealing plate is connected with the corresponding exhaust flue, the inner side of each sealing plate flue is not insulated, the outer part of each sealing plate flue is provided with a heat insulation layer, the two layers of heat insulation layers are arranged, the inner layer is made of rock wool, the outer layer is made of molded heat insulation layers.
Since the high-well thermal power plant 9FB combustion engine is put into operation, because the axial displacement is more than 80mm under the thermal state condition of the exhaust diffusion section, the exhaust sealing plate always has the smoke leakage phenomenon, the temperature of the heat-preservation outer protecting plate is more than 250 ℃, and the maximum temperature reaches 300 ℃, although the heat preservation is carried out for 3 times, the effect is not ideal. The 1 # combustion engine also has an unsafe event that the temperature measuring point (TTIB) cable of the 2 # bearing tunnel of the combustion engine melts to cause the unit to jump due to overtemperature. And a vibration measuring point cable of a No. 2 bearing of the gas turbine is arranged in the area, so that the damage to thermal elements is serious, and the safe and stable operation of the unit is influenced. Meanwhile, due to over-temperature, the temperature in the air duct of the ventilating and cooling fan of the exhaust section housing reaches over 100 ℃, the motor bearing of the ventilating and cooling fan (88 BD) runs at an over-temperature risk, and the heat efficiency and the continuous running safety of the unit are seriously affected by the defects.
The utility model has the following contents:
the utility model aims at solving the problem that there is flue gas leakage in former flue gas baffle, has influenced the safety and stability operation of unit, provide one kind and increase one deck vortex baffle outside former flue gas baffle to prevent that the flue gas reveals blocks omega type flexible coupling vortex baffle of flue gas leakage.
The above purpose is realized by the following technical scheme:
an omega-shaped flexible connection turbulence baffle for blocking smoke leakage is composed of two stainless steel plates distributed up and down and an omega-shaped flexible connection fixed between the two stainless steel plates, wherein the omega-shaped flexible connection is a circular structure surrounded by a plurality of omega-shaped flexible connection plates which are overlapped in a staggered mode;
the omega-shaped flexible connecting plate is a structure formed by pressing a group of stainless steel thin plates and heat-resistant fiber cloth which are arranged at intervals.
The omega-shaped flexible connection turbulence baffle for blocking the flue gas leakage is of a structure formed by pressing two layers of stainless steel thin plates and three layers of heat-resistant fiber cloth at intervals.
Stop omega type flexible coupling vortex baffle of flue gas leakage, the thickness of stainless steel plate be 3 mm.
The omega-shaped flexible connection turbulence baffle for blocking the smoke leakage is 5mm thick.
Has the advantages that:
1. the utility model discloses an install the omega type flexible coupling vortex baffle that blocks the flue gas leakage additional behind former flue gas baffle, it is obvious to block the flue gas effect of leaking, has solved the problem of dilatation joint department overtemperature. The temperature of the heat-preservation outer guard plate at the joint of the exhaust diffusion section and the exhaust flue is reduced from more than 250 ℃ to about 100 ℃, and the safety and reliability of the unit operation are improved.
Description of the drawings:
FIG. 1 is a schematic structural view of the utility model after installation;
FIG. 2 is a schematic structural diagram of the present invention;
FIG. 3 is a schematic structural diagram of an omega-type flexible connection;
in the figure: 1. an inner insulating layer; 2. a gas baffle; 3. a turbulence baffle; 4. an outer insulating layer; 5. covering a skin; 6. a stainless steel plate; 7. omega-type flexible connection; 8. a stainless steel sheet; 9. a heat-resistant fiber cloth.
The specific implementation mode is as follows:
example 1:
the utility model provides a block omega type flexible coupling vortex baffle of flue gas leakage, this vortex baffle 3 is by two corrosion resistant plate 6 that distribute from top to bottom and fix two corrosion resistant plate between omega type flexible coupling 7 constitute, omega type soft sealing adopts 5 layer structures, every layer homoenergetic undertakes direct current flue gas and erodees, omega type flexible coupling enclose synthetic circular structure by two adjacent crisscross lapped a plurality of omega type flexible coupling boards that misplace, every section dislocation overlap joint reserves about 60mm overlap joint mouth, fixes on corrosion resistant plate through two rows of metal anchor nails.
Omega type soft connecting plate be by the structure that a set of stainless steel sheet 8 and the heat-resisting fiber cloth 9 suppression of interval arrangement formed, offset the mechanical force of equipment inflation and displacement, this vortex baffle sets up outside former gas baffle 2, between interior heat preservation 1 and outer heat preservation 4, the outer heat preservation outside sets up covering 5.
Example 2:
