Abstract
The invention discloses a sealing device for a manhole door of a waste heat boiler of a gas turbine. The sealing device comprises a boiler shell guard board, a doorframe and the manhole door, wherein the doorframe is connected with the boiler shell guard board and takes the shape of a ladder; a manhole door lining matched with the doorframe for use is arranged on the manhole door, and a ceramic fiber blanket is filled between the manhole door and the manhole door lining; a sealing piece is arranged between the doorframe and the manhole door lining; and the sealing piece is arranged between the horizontal position of the ladder-shaped doorframe and the horizontal position of the ladder-shaped manhole door lining. The sealing device for the manhole door of the waste heat boiler of the gas turbine has the following advantages that the ladder-shaped doorframe and the manhole door lining are adopted, so that the flow of high-temperature flue gas is effectively blocked; and ceramic-fiber braided ropes are arranged at the gap between the doorframe and the manhole door lining, so that the high-temperature flue gas is thoroughly prevented from overflowing.
Description
Technical field
The present invention relates to a kind of gas-turbine waste heat boiler, particularly a kind of gas-turbine waste heat boiler manhole door sealing device.
Background technology
For making things convenient for gas-turbine waste heat boiler maintenance and repair to boiler internal equipment when stopping transport, need to be in the flue zone and the heating surface zone settle manhole door, manhole door not only will make the people come in and go out safely, and to guarantee the isolation of waste heat boiler internal environment in service and external environment condition, guarantee that high-temperature flue gas does not leak.
Use at present the manhole door device on gas-turbine waste heat boiler to be formed by the doorframe that consists of with flanged plate and furnace shell backplate, connect to form door opening by doorframe and furnace shell backplate again, manhole door is inserted in door opening, be the convenient manhole door of opening smoothly, usually reserve the gap of 2mm between each limit of manhole door and doorframe.The shortcoming of this manhole door is: when boiler operatiopn, high-temperature flue gas is easy to overflow from the gap between manhole door and the doorframe, thereby easily to causing potential safety hazard around the manhole door of the boiler outside.
Summary of the invention
Technical problem to be solved by this invention is the gas-turbine waste heat boiler manhole door sealing device that provides a kind of effective prevention high-temperature flue gas to leak.
For solving the problems of the technologies described above, gas-turbine waste heat boiler manhole door sealing device provided by the invention, it comprises furnace shell backplate, the doorframe and the manhole door that are connected with the furnace shell backplate, described doorframe is stepped, described manhole door is provided with the manhole door door lining that is used with doorframe, be filled with ceramic fiber blanket between described manhole door and the manhole door door lining, be provided with seal between doorframe and the manhole door door lining, described seal is located between stairstepping doorframe horizontal level and the stairstepping manhole door door lining horizontal level.Adopt the stepped design mode, effectively hindered flowing of high-temperature flue gas, that ceramic fiber blanket integrates is fire-resistant, heat insulation, be incubated, and therefore has good sealing effectiveness, has prevented simultaneously the loss of heat in the waste heat boiler, has good heat insulation effect.
As preferably, described seal is comprised of ceramic fibre kernmantle and high-dimensional paper, and described high-dimensional paper is wrapped in the outside of ceramic fibre kernmantle, and the lap-joint at high-dimensional paper two ends is fixedly connected with doorframe.The ceramic fibre kernmantle has good sealing effectiveness, and high-dimensional paper has again well fire-resistant, fire-proof function, under the hot environment of waste heat boiler, has thoroughly stoped overflowing of high-temperature flue gas.
As preferably, be enclosed with two ceramic fibre kernmantles in the described high-dimensional paper, the lap-joint at high-dimensional paper two ends is provided with tapping screw and packing ring, and described seal is fixed on the doorframe by tapping screw and packing ring, and described tapping screw is located at the centre of two ceramic fibre kernmantles.Make sealing effectiveness reach best.
As preferably, the thickness of described tapping screw head is less than the thickness that is wrapped in the ceramic fibre kernmantle in the high-dimensional paper.When preventing from closing manhole door, the manhole door door lining directly is expressed to the head of tapping screw, and not with the compacting of ceramic fibre kernmantle, affects sealing effectiveness.
After adopting above structure, gas-turbine waste heat boiler manhole door sealing device of the present invention compared with prior art has the following advantages:
When 1, conveniently opening manhole door smoothly, has good sealing effectiveness.
2, adopt stepped design doorframe and manhole door door lining, effectively hindered flowing of high-temperature flue gas;
3, doorframe and manhole door door lining gap location arrange the ceramic fibre kernmantle, thoroughly stop high-temperature flue gas to overflow.
