Description
Technical field
The present invention relates to horizontal rubbish waste heat boiler technical field, specially a kind of horizontal rubbish Economizer of Heat Recovery Boiler pipe
Gas baffle structure between screen.
Background technique
It is burned in bedroom waste heat boiler back-end ductwork in fire grate garbage, is generally disposed with superheater, reheater, economizer,
It is structurally characterized in that convection heating surface tube bank is vertically hung in horizontal flue, restrains by upper and lower two concentrate tubes and vertical tube group
At being arranged by rows in back-end ductwork along boiler width direction.Wherein economizer region is compared to other heating surface areas
Domain, tube bank arrangement is intensive, and flue gas flow rate is higher, and unreasonable, smoke corridor easy to form is arranged in tube bank.But since structure limits
System, causes two groups of tube panel gaps of economizer or so excessive, a large amount of flue gases can circulate by this gap, walk to form flue gas
Corridor.The flue gas flow rate in usual smoke corridor region is 3 ~ 4 times bigger than normal flow again, therefore the economizer tube in the position is ground
Damage is much more serious than normal wear, there is very big security risk.
Summary of the invention
In order to solve it is existing because smoke corridor there are due to cause economizer tube serious wear, there is very big security risk
The problem of, the present invention provides gas baffle structures between a kind of horizontal rubbish Economizer of Heat Recovery Boiler tube panel, can effectively subtract
The abrasion of few economizer tube, improves the reliability and safety of boiler operatiopn.
Its technical solution is such that gas baffle structure between a kind of horizontal rubbish Economizer of Heat Recovery Boiler tube panel, packet
Include left tube panel and right tube panel, which is characterized in that the gap location of the left tube panel and the right tube panel is equipped with baffle mechanism, described
Baffle mechanism includes strip baffle, and the strip baffle is installed on the left tube panel or the right tube panel by U bolt, described
The supporting block for being used to support the U bolt, the strip baffle and the left pipe are installed on left tube panel or the right tube panel
Partition is provided between screen or the right tube panel.
It is further characterized by the strip baffle is constituted by welding at least two blocks of steel plates on angle steel；
The U bolt both ends are separately connected the angle steel and the steel plate and are fixed by nut；
The strip baffle is installed on the left tube panel or the right tube panel by two U bolts；
The supporting block is the round steel for being welded in the left tube panel or the right tube panel；
The partition is welded in the strip baffle.
After adopting the structure of the invention, original biggish gap is separated by two free air spaces by strip baffle, subtracted
The abrasion for having lacked economizer tube is realized by partition and U bolt and is fixed, improves the reliability and safety of boiler operatiopn.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is structural schematic diagram at I in Fig. 1；
Fig. 3 be in Fig. 2 A to baffle arrangement structural schematic diagram；
Fig. 4 is structural schematic diagram at II in Fig. 2；
Fig. 5 be in Fig. 4 B to baffle mechanism structural schematic diagram.
Specific embodiment
See Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5, gas baffle knot between a kind of horizontal rubbish Economizer of Heat Recovery Boiler tube panel
Structure comprising the gap location of Zuo Guanping 1 and right tube panel 2, Zuo Guanping 1 and right tube panel 2 is equipped with baffle mechanism, and baffle mechanism includes
Strip baffle 3, strip baffle 3 are installed on right tube panel 2 by two U bolts 4, are equipped on right tube panel 2 and are used to support U-shaped spiral shell
The supporting block 5 of bolt 4, is provided with partition 6 between strip baffle 2 and right tube panel 2, for convenience, partition 6 is directly fixed on strip gear
Plate 3.Specifically, strip baffle 3 is constituted by welding two pieces of steel plate 3-2 on angle steel 3-1,4 both ends of U bolt are separately connected angle steel 3-
1 and steel plate 3-2 is simultaneously fixed by nut 7, and structure is simple, and materials are convenient, and installing and dismounting also facilitates；Supporting block 5 is to be welded in the right side
The round steel of tube panel 2 effectively prevent strip baffle 3 to glide, and does not need the large area welding on tube panel, can avoid damage to pipe
Son.
