Abstract
The invention relates to a large-sized refuse burning boiler, and particularly relates to a flue gas damper device used between coal economizer tube panels in the refuse burning boiler. The flue gas damper device used between the coal economizer tube panels is simple in structure, does not damage pipes and can conveniently solve the problems of formation of flue gas passages between the coal economizer tube panels and pipe abrasion. The flue gas damper device comprises the coal economizer tube panels and is characterized in that angle iron is arranged at the outer sides of the coal economizer pipes through U-shaped bolts.
Description
Technical field
The present invention relates to bulky refuse burning boiler, be specially in garbage burning boiler, gas baffle device between a kind of economizer tube panel.
Background technology
In bulky refuse burning boiler, between economizer tube panel and tube panel, gap is comparatively large, and flue gas, through out-of-date, easily forms smoke corridor, reduces the heat-transfer effect of overall heating surface, and easily produces wearing and tearing to pipe.Taked directly to be welded on pipe side with band steel, because pipe vertical direction is longer, take this measure easily in the process of fielding welding, to produce injury to pipe, as welded stress, pipe deformation, weld defect etc., welding job amount is also relatively large in the past.
Summary of the invention
In order to solve the problem, the invention provides gas baffle device between a kind of economizer tube panel, its structure is simple, can not cause damage, can solve easily between economizer tube panel and form smoke corridor and tube wear problem pipe.
Its technical scheme is such: gas baffle device between a kind of economizer tube panel, and it comprises economizer tube panel, it is characterized in that, angle steel is arranged at outside economizer pipe by U bolt.
It is further characterized in that, described angle steel sidepiece is provided with steel plate, and described steel plate has with on described angle steel the installing hole coordinated, and described U bolt is fixedly connected with described angle steel through described installing hole by nut;
Composition backing on described angle steel, described economizer pipe is arranged between described backing plate and described U bolt;
Described angle steel sidepiece is evenly provided with multiple steel plate from top to bottom, and described economizer pipe is welded with Rod Bracing plate, and described U bolt lower end is supported on described Rod Bracing plate.
After adopting structure of the present invention, angle steel is installed on outside economizer pipe by U bolt, avoid the defect be directly welded in outside economizer pipe, can not cause damage to pipe, angle steel stops that flue gas can solve between economizer tube panel easily and forms smoke corridor and tube wear problem.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 be in Fig. 1 A to angle steel schematic diagram;
Fig. 3 is Fig. 1 plan structure schematic diagram;
Fig. 4 is I place's enlarged diagram in Fig. 3.
Detailed description of the invention
See Fig. 1, shown in Fig. 2, Fig. 3, Fig. 4, gas baffle device between a kind of economizer tube panel, it comprises economizer tube panel 1, and angle steel 2 is arranged at outside economizer pipe 4 by U bolt 3.
The welding of angle steel 2 sidepiece is provided with steel plate 5, and steel plate 5 has with on angle steel 2 installing hole coordinated, and U bolt 3 is fixedly connected with angle steel 2 through installing hole by nut 6; Composition backing 7 on angle steel 2, economizer pipe 4 is arranged between backing plate 7 and U bolt 3, and economizer pipe 4 does not directly contact with angle steel 2, protection economizer pipe.
Angle steel 2 sidepiece is evenly provided with three steel plates 5 from top to bottom, economizer pipe 4 is welded with Rod Bracing plate 8, and U bolt 3 lower end of bottom is supported on Rod Bracing plate 8, prevents angle steel 2 landing downwards, further protection economizer pipe 4.
