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 that waste heat and the rear heat producing of combustible burning thereof in waste gas, waste material or the waste liquid utilizing in various industrial process are heated to water in the boiler of certain working medium.Have oil burning boiler that smoke box, flue residue heat recycle, gas fired-boiler, coal-burning boiler also referred to as waste heat boiler, waste heat boiler can be produced hot water or steam by waste heat recovery and supply with other workshop section and use.
Waste heat boiler is in long-term use procedure, and boiler shell exposed part especially gas baffle door usually can produce liquid sulfuric acid and be corroded because of the sulfide in flue gas and steam effect.Gas baffle door is after being corroded, and its sealing property just cannot be guaranteed, and causes flue gas to leak outside.At present, the countermeasure conventional for this situation is, once find that gas baffle door housing occurs that hard stop, changes operation to gas baffle door, or gas baffle door is welded to maintenance etc. because housing corrosion produces the phenomenon that flue gas leaks outside.Because gas baffle door weight, volume are all larger, be not easy to move, in maintenance activity process, there is larger difficulty.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of high-temperature flue gas baffle door shell structure is provided, this shell structure adopts modularized design, and dismounting is flexible, is convenient to follow-up maintenance maintenance.
According to technical scheme of the present invention: a kind of high-temperature flue gas baffle door shell structure, it is characterized in that: comprise base, lower house, upper shell, described lower house is fixedly connected on described base by base plate, upper shell is fixedly connected with lower house by split adpting flange, upper shell openend is connected with upper cover, described upper shell is provided with the first sealing air inlet tube that is communicated with housing inner chamber, on upper cover, be connected with the second sealing air inlet tube, the junction of upper cover and upper shell is provided with bearing block.
As a further improvement on the present invention, the junction of described upper cover and upper shell is provided with adpting flange reinforcement, and in upper shell upper end, transverse stiffener rib is set, the length of described upper cover is less than the length of upper shell, on the horizontal plane that described upper cover is connected with upper shell, be provided with flat shrouding, upper cover surface is vertically to being provided with vertical closure plate; The junction of bearing block and upper shell and upper cover is provided with reinforcement.
As a further improvement on the present invention, the uniform longitudinal rein forcement that is provided with of described lower house and upper shell surface.
As a further improvement on the present invention, on described upper shell surface, establish son with the junction of upper cover and have hanger.
Technique effect of the present invention is: product of the present invention adopts split-type structural design, convenient transportation and assembling operation, the operation of being also convenient to load fiberboard in housing and covering interior lining panel on fiberboard simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
In Fig. 1, comprise base 1, lower house 2, upper shell 3, split adpting flange 4, adpting flange reinforcement 5, bearing block 6, upper cover 7, the 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, comprise base 1, lower house 2, upper shell 3, described lower house 2 is fixedly connected on described base 1 by base plate 5, upper shell 3 is fixedly connected with lower house 2 by split adpting flange 4, upper shell 3 openends are connected with upper cover 7, described upper shell 3 is provided with the first sealing air inlet tube 8 that is communicated with housing inner chamber, on upper cover 7, be connected with the second sealing air inlet tube 9, upper cover 7 is provided with bearing block 6 with the junction of upper shell 3.
Described upper cover 7 is provided with adpting flange reinforcement 5 with the junction of upper shell 3, and in upper shell 3 upper ends, transverse stiffener rib 6 is set, the length of described upper cover 7 is less than the length of upper shell 3, on the horizontal plane that described upper cover 7 is connected with upper shell 3, be provided with flat shrouding 11, upper cover 7 surfaces are vertically to being provided with vertical closure plate 10; Bearing block 6 is provided with reinforcement with the junction of upper shell 3 and upper cover 7.
Described lower house 2 and the upper shell 3 uniform longitudinal rein forcements 12 that are provided with in surface.
On described upper shell 3 surfaces, establish son with the junction of upper cover 7 and have hanger 8.
The course of work of the present invention is as follows: by housing is carried out to architecture advances, three-way body is divided into 2 two sections of upper shell 3, lower houses, in building site, assemble complete use, each section of faying face need be at fielding welding, load respectively aluminosilicate fiberboard in upper and lower casing after, downstream direction covers interior lining panel simultaneously, each nut on the interior lining panel of spot welding simultaneously.Product dismounting of the present invention, combination are all more for convenience, when upper shell 3 is connected with lower house 2, can lift by crane the hanger 8 on upper shell 3 by hanging device, upper shell 3 is transferred to lower house 2 tops, then fall to being aligned on lower house 2, be bolted connection.
