Abstract
The utility model provides a baffle device for organizing smoke to flow in a horizontal type waste heat boiler, so as to realize the even distribution of the smoke in flues, improve the heat exchange efficiency of the boiler, improve the desulfuration and denitration efficiencies and ensure the safety and reliability of the boiler. The baffle device comprises a boiler inlet, two flues with different elevations and an inlet-section outlet, and is characterized in that a baffle which is provided with gratings is distributed in the vertical surface of the flue close to the boiler inlet; the outer frame of the baffle is clung to the inner wall of the flue; and the gratings are arranged toward the inclined upward side of the inlet-section outlet.
Description
Technical field
The utility model relates to the technical field of structures of horizontal type waste heat boiler, is specially the retaining device of a kind of horizontal type waste heat boiler inner tissue flow of flue gas.
Background technology
Existing horizontal type waste heat boiler entrance flue structure is generally the combination of two sections band different angles elevation angle flues, behind the water conservancy diversion of flue gas through two sections different elevations angle flues, gets into heat exchange pipeline section and water-steam and carries out heat exchange.The size at the elevation angle through regulating gas approach, it is comparatively even that flue gas is distributed in flue.
In actual motion, in entrance, do not run off in order to ensure the heat of flue gas, entrance length generally all designs shorter; On the other hand, the inlet flow velocity of flue gas is bigger, and this elevation angle that causes entrance organizes and leads dynamics not enough to flow of flue gas; In the entrance exit; Before promptly getting into heat exchanging segment and carrying out heat exchange, flue gas still can not be in flue even must the distribution, the main flow of flue gas is roughly carried out heat exchange between the Lower Half of boiler and heat exchange pipeline; This causes the heat exchange efficiency of boiler to descend easily; And the flying dust in the flue gas flows along with the Lower Half that the flue gas main flow also concentrates on boiler, causes the abrasion of relevant device easily, and the heat exchange pipeline that also causes easily being correlated with rocks because of unbalance stress even comes off; Consider the desulfuring and denitrifying apparatus shape that on the boiler cross section, is evenly distributed simultaneously,, will influence denitrification efficiency if fume centralized flows in the boiler Lower Half.
Summary of the invention
To the problems referred to above, the utility model provides the retaining device of a kind of horizontal type waste heat boiler inner tissue flow of flue gas, and it realizes that flue gas distributes uniformly in flue, has improved the boiler heat exchange efficiency, improved denitrification efficiency and has guaranteed that boiler safety is stable.
The retaining device of a kind of horizontal type waste heat boiler inner tissue flow of flue gas; Its technical scheme is such: it comprises boiler inlet, two sections different elevations angle flues, entrance exit; It is characterized in that: be furnished with the baffle plate that has grid in the facade near the said flue of said boiler inlet; The fit inwall of said flue of the housing of said baffle plate, said grid is the layout obliquely towards said entrance exit.
It is further characterized in that: said grid is from the horizontal by 0 °～55 ° angles.
Said grid is cumulative big with become contending of horizontal direction from bottom to top.
After adopting the said structure of the utility model; Flue gas by grid with elevation angle water conservancy diversion; Change flow direction; Through the shape that in flue, is evenly distributed behind the baffle plate, can effectively improve the flow distribution of flue gas in waste heat boiler, improved the boiler heat exchange efficiency, improved denitrification efficiency and guaranteed that boiler safety is stable.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation enlarged drawing of the baffle plate that has grid of the utility model.
The specific embodiment
See Fig. 1, Fig. 2; It comprises boiler inlet 1, leading portion flue 2, back segment flue 3, entrance exit 4; Entrance exit 4 is led to high-temperature heat transfer section 5, desulfuring and denitrifying apparatus 6, low-temperature heat exchange section 7, chimney 8 successively; Be furnished with the baffle plate 10 that has grid 9 in the facade near the leading portion flue 2 of boiler inlet 1, the inwall of the housing applying leading portion flue 2 of baffle plate 10, grid 9 is the layout obliquely towards the entrance exit; 0 ° from the horizontal by the angle～55 ° of grids 9, grid 9 are cumulative big with become contending of horizontal direction from bottom to top.
