Abstract
The utility model provides a flue sealing structure of a vertical gas turbine exhaust-heat boiler, which ensures that smoke is effectively prevented from flowing out of a heating surface module during an operation process of the boiler. The flue sealing structure comprises a flue wallboard, the heating surface module, a tube plate and a smoke baffle. The smoke baffle is located obliquely above the heating surface module and connected with the tube plate above the heating surface module in welded mode. The flue sealing structure is characterized in that a fixing separating plate is installed on one side of the flue wallboard close to the heating surface module, and both ends of a glass fiber cotton connecting plate are respectively connected with the fixing separating plate and the smoke baffle.
Description
Technical field
The utility model relates to the technical field of waste heat boiler structure, is specially a kind of flue hermetically-sealed construction of vertical gas-turbine waste heat boiler.
Background technology
In vertical gas-turbine waste heat boiler body flue, owing between heating surface module and the flue wallboard space is arranged, therefore need prevent that flue gas from flowing out in that the flue gas sealing device is set between heating surface module and the wallboard outside the heating surface module.Existing vertical gas-turbine waste heat boiler flue hermetically-sealed construction connects to form through between wallboard and gas baffle, adding stationary barrier; The back easy deformation of being heated is in operation; Special deflection is big in the waste heat boiler of the big swell increment of high temperature, is unfavorable for the flow of flue gas on isolated both sides.
Summary of the invention
To the problems referred to above, the utility model provides a kind of flue hermetically-sealed construction of vertical gas-turbine waste heat boiler, and it guarantees that boiler isolated effectively flue gas in running flows out outside the heating surface module.
A kind of flue hermetically-sealed construction of vertical gas-turbine waste heat boiler; Its technical scheme is such: it comprises flue wallboard, heating surface module, tube sheet; Gas baffle, said gas baffle are positioned at the side top of said heating surface module, and said gas baffle is welded to connect the said tube sheet of heating surface module top; It is characterized in that: said flue wallboard is equipped with stationary barrier near a side of said heating surface module, and the two ends of glass fibre cotton connecting plate connect stationary barrier, gas baffle respectively.
It is further characterized in that: the upper surface of said stationary barrier is connected through said glass fibre cotton connecting plate with the side of said gas baffle near said flue wallboard;
Said glass fibre cotton connecting plate is the circular arc plate, and its circular arc is towards said heating surface module side;
Said stationary barrier and said gas baffle stagger up and down in flue.
After adopting the structure of the utility model; When waste heat boiler moves; Stationary barrier is motionless, and glass fibre cotton connecting plate and gas baffle move with the heating surface module is three-dimensional, and the glass fibre cotton connecting plate can prevent that flue gas from flowing outside module; Can absorb simultaneously the swell increment of heating surface module when boiler operatiopn and blowing out again, it guarantees that boiler isolated effectively flue gas in running flows out outside the heating surface module.
Description of drawings
Fig. 1 is the front view structural representation block diagram of the utility model.
The specific embodiment
See Fig. 1; It comprises flue wallboard 1, heating surface module 8, tube sheet 7; Gas baffle 6, gas baffle 6 are positioned at the side top of heating surface module 8, and gas baffle 6 is welded to connect the tube sheet 7 of heating surface module 8 tops; Flue wallboard 1 is equipped with stationary barrier 2 near a side of heating surface module 8, and the two ends of glass fibre cotton connecting plate 4 connect stationary barrier 2, gas baffle 6 respectively.The upper surface of stationary barrier 2 and gas baffle 6 are fastenedly connected glass fibre cotton connecting plate 4 through bolt 3,5 respectively near a side of flue wallboard 1; Glass fibre cotton connecting plate 4 is the circular arc plate, and its circular arc is towards heating surface module 8 sides; Stationary barrier 2 staggers up and down in flue with gas baffle 6.
