Abstract
The invention provides a garbage waste heat boiler flue gas flow field optimizing structure, which aims to change the trend of flue gas flow by arranging a flue gas folding structure in a flow field, and has the technical key points that: a smoke folding structure is arranged at the smoke turning position in the flow field and used for changing the trend of the smoke flow field. The cigarette structure of turning over is the water conservancy diversion angle. The longitudinal section of the diversion angle is triangular. The invention changes the flow direction of the flue gas in the flow field through the arranged flue gas folding structure, particularly, a triangular diversion angle is arranged at the flue gas turning position in the flow field to serve as the flue gas folding structure, the trend of the original flue gas flow field is forcibly changed through the diversion angle, the flue gas backflow generated locally and the scouring of a rear wall are reduced, the flue gas is prevented from being retained during reversing, and the problems of poor heat exchange, corrosion and the like caused by the flue gas backflow and the local reduction type atmosphere generated frequently in the conventional garbage waste heat boiler can be effectively solved.
Description
The technical field is as follows:
the invention relates to the technical field of boiler power generation, in particular to a garbage waste heat boiler smoke flow field optimizing structure.
Background art:
when the waste heat boiler is used, when the waste on the grate is incinerated, a larger excess air coefficient is generally needed to ensure the sufficient combustion of the waste, and the corrosion to various parts of the boiler caused by the insufficient combustion of the waste is reduced. As shown in fig. 1, after flue gas generated by burning garbage is turned, poor flow field and even flue gas backflow often occur in local areas to form a reducing atmosphere, which not only does not exchange heat well, but also causes the phenomenon that the heating surface of each equipment of a boiler suffers local erosion corrosion.
The invention content is as follows:
the invention provides an optimized flue gas flow field structure of a garbage waste heat boiler, which can optimize flue gas flow by arranging a smoke folding structure in the flow field, and effectively solves the problems of poor heat exchange, corrosion and the like caused by flue gas backflow and local reduction-type atmosphere generation frequently occurring in the conventional garbage waste heat boiler.
The invention discloses a garbage waste heat boiler smoke gas flow field optimizing structure, which adopts the technical scheme that: a smoke folding structure is arranged at the smoke turning position in the flow field and used for changing the trend of the smoke flow field.
As a further improvement of the invention, the cigarette folding structure is a flow guide angle.
As a further improvement of the present invention, the longitudinal section of the diversion angle is triangular.
The invention has the beneficial effects that: the invention changes the flow direction of the flue gas in the flow field through the arranged flue gas folding structure, particularly, a triangular diversion angle is arranged at the flue gas turning position in the flow field to serve as the flue gas folding structure, the trend of the original flue gas flow field is forcibly changed through the diversion angle, the flue gas backflow generated locally and the scouring of a rear wall are reduced, the flue gas is prevented from being retained during reversing, and the problems of poor heat exchange, corrosion and the like caused by the flue gas backflow and the local reduction type atmosphere generated frequently in the conventional garbage waste heat boiler can be effectively solved.
Description of the drawings:
FIG. 1 is a schematic diagram of a conventional flow field;
FIG. 2 is a schematic structural view of the present invention;
in the figure, 1 is a flow field, and 2 is a smoke folding structure.
The specific implementation mode is as follows:
the following detailed description of specific embodiments of the invention, taken in conjunction with the accompanying drawings, will be readily understood and appreciated by those skilled in the art as the same becomes better understood and appreciated by those skilled in the art:
as shown in fig. 1, the waste heat boiler of the present invention optimizes the flue gas flow field structure, and a flue gas turning part in the flow field 1 is provided with a flue gas folding structure 2 for changing the flue gas flow field trend. The smoke folding structure 2 may be a diversion angle or a structure that can arbitrarily change the smoke flow direction, and the longitudinal section of the diversion angle in this embodiment is a triangle.
Through folding cigarette structure 2 among this embodiment to forejudge the trend that the flue gas flow field changes original flue gas flow field compulsorily through numerical simulation, can alleviate the flue gas backward flow that local produced and the phenomenon of the washing away of back wall, can strengthen the heat transfer effect of flue gas, can effectively solve the frequent flue gas backward flow that appears of present rubbish exhaust-heat boiler, the heat transfer that local production reduction type atmosphere caused is not good, corrode the scheduling problem.
The above is a specific embodiment of the present invention, and it should be noted that the specific embodiment is not to be construed as limiting the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
