Abstract
The invention belongs to the technical field of heat recovery boilers and particularly relates to a shell structure of a high-temperature smoke baffle door. The shell structure comprises a base, an upper shell body and a lower shell body. The lower shell body is fixedly connected to the base through a base plate. The upper shell body is fixedly connected to the lower shell body through a split connecting flange. An upper head is connected to an opening end of the upper shell body. The upper shell body is provided with a first sealing air inlet pipe communicated with a chamber in the shell. A second sealing air inlet pipe is connected to the upper head. A bearing seat is arranged on a joint of the upper head and the upper shell body. The shell structure adopts a split type structural design and is convenient to convey, assemble, the shell is filled with fiber plates conveniently and the lining plates cover the fiber plates conveniently.
Description
Technical field
The invention belongs to waste heat boiler technical field, specifically a kind of high-temperature flue gas baffle door shell structure.
Background technology
Waste heat boiler, as the term suggests refer to using the waste heat in the waste gas in various industrial process, waste material or waste liquid and its
The heat produced after combustible burning is heated to water in the boiler of certain working medium.Recycle with smoke box, flue residue heat
Oil burning boiler, gas fired-boiler, coal-burning boiler are also referred to as waste heat boiler, and waste heat boiler can produce hot water or steaming by waste heat recovery
Vapour is used supplying other workshop sections.
, during life-time service, especially gas baffle door usually can be because of cigarette for boiler shell exposed part for waste heat boiler
Sulfide in gas produces liquid sulfuric acid with steam effect and is corroded., after being corroded, its sealing property is just for gas baffle door
Cannot be guaranteed, cause flue gas to leak outside.At present, the countermeasure commonly used in this case is, once find gas baffle door shell
Body occurs producing the phenomenon of flue gas leakage because housing corrodes, and hard stop carries out replacement operation to gas baffle door, or right
Gas baffle door carries out welding maintenance etc..As gas baffle door weight, volume are larger, movement is not easy to, in maintenance activity
During, there is larger difficulty.
The content of the invention
The present invention is directed to the problems referred to above, there is provided a kind of high-temperature flue gas baffle door shell structure, the shell structure adopt module
Change design, dismounting is flexible, is easy to follow-up maintenance to maintain.
According to technical scheme：A kind of high-temperature flue gas baffle door shell structure, is characterized in that：Including base, under
Housing, upper shell, the lower house are fixedly connected on the base by base plate, and upper shell passes through split adpting flange and lower casing
Body is fixedly connected, and upper shell opening is connected with upper cover, and the first sealing air of housing cavity is communicated with the upper shell
Inlet tube, is connected with the second sealing air inlet tube on upper cover, and upper cover is provided with bearing block with the junction of upper shell.
As a further improvement on the present invention, the upper cover is provided with adpting flange reinforcement with the junction of upper shell
Muscle, and transverse stiffener rib is set in upper shell upper end, the length of the length of the upper cover less than upper shell, the upper cover with it is upper
It is provided with flat shrouding on the horizontal plane that housing is connected, upper cover surface is vertically to being provided with vertical closure plate；Bearing block and upper shell
And the junction of upper cover is provided with reinforcement.
As a further improvement on the present invention, the lower house has been uniformly arranged longitudinal rein forcement with upper shell surface.
As a further improvement on the present invention, setting son with the junction of upper cover on the upper shell surface has hanger.
The method have technical effect that：Product of the present invention is designed using split-type structural, convenient to transport and assembling operation,
Also allow for simultaneously fibre board is loaded in housing and the operation of interior lining panel is covered on fibre board.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Left views of the Fig. 2 for Fig. 1.
Specific embodiment
Below in conjunction with the accompanying drawings the specific embodiment of the present invention is further described.
In Fig. 1, including base 1, lower house 2, upper shell 3, split adpting flange 4, base plate 5, bearing block 6, upper cover 7,
First sealing air inlet tube 8, the second sealing air inlet tube 9, vertical closure plate 10, flat shrouding 11, longitudinal rein forcement 12 etc..
As shown in figure 1, the present invention is a kind of high-temperature flue gas baffle door shell structure, including base 1, lower house 2, upper shell
3, the lower house 2 is fixedly connected on the base 1 by base plate, and upper shell 3 is solid with lower house 2 by split adpting flange 4
Fixed to connect, 3 opening of upper shell is connected with upper cover 7, and the first sealing air that housing cavity is communicated with the upper shell 3 enters
Mouth pipe 8, is connected with the second sealing air inlet tube 9 on upper cover 7, and upper cover 7 is provided with bearing block with the junction of upper shell 3
6。
The upper cover 7 is provided with adpting flange reinforcement with the junction of upper shell 3, and arranges in 3 upper end of upper shell
Transverse stiffener rib, the length of the upper cover 7 are less than the length of upper shell 3, the level that the upper cover 7 is connected with upper shell 3
It is provided with flat shrouding 11 on face, 7 surface of upper cover is vertically to being provided with vertical closure plate 10；Bearing block 6 and upper shell 3 and upper cover 7
Junction be provided with reinforcement.
The lower house 2 has been uniformly arranged longitudinal rein forcement 12 with 3 surface of upper shell.
Son is set with the junction of upper cover 7 on 3 surface of the upper shell has hanger 13.
The course of work of the present invention is as follows：By carrying out structure improvement to housing, by three-way body be divided into upper shell 3, under
2 two sections of housing, assembles complete use in building site, and each section of faying face need to be in fielding welding, while loading in upper and lower shell body respectively
After aluminosilicate fiberboard, downstream direction covers interior lining panel, while each nut on spot welding interior lining panel.Product dismounting of the present invention, combination
It is more convenient, when upper shell 3 is attached with lower house 2, the hanger on upper shell 3 can be lifted by crane by hanging device
13, upper shell 3 is transferred to above lower house 2, then is fallen to being aligned on lower house 2, is bolted connection.
