Abstract
The utility model discloses a variable cross section flue board that flow equalizes, including the variable cross section flue and the board that flow equalizes, variable cross section flue cross section is improved level and is set up the splayed board that flow equalizes. The utility model discloses the water conservancy diversion to the variable cross section flue can be realized well, the superperformance of boiler is guaranteed, simple structure, the practicality is strong, and it is convenient to change, and the operation is reliable, and the maintenance cost is low.
Description
Technical field
The utility model relates to boiler plant technical field, especially relates to a kind of variable cross-section flue flow equalizing plate.
Background technology
Homogenizing plate is widely used in the fluidic structures having structure to change, even to realize flow velocity in fluidic structures.In order to ensure the superperformance of boiler, avoiding in flue, occur serious flue gas bias current, therefore homogenizing plate rational in infrastructure must be set in the appropriate location of flue, to arrive in whole flue the uniform object of flue gas flow rate in each cross section with this.
Utility model content
In order to overcome above-mentioned existing technological deficiency, it is simple that the purpose of this utility model is to provide a kind of structure, and water conservancy diversion is effective, reliable boiler SCR denitration device variable cross-section flue flow equalizing plate.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
The technical program is a kind of variable cross-section flue flow equalizing plate structure, comprises variable cross-section flue and homogenizing plate; Described variable cross-section flue cross section is horizontally disposed with splayed homogenizing plate.Described homogenizing plate is arranged at the variable cross-section flue outlet of flue gas flow direction, is that herringbone is arranged along flow of flue gas direction.
As optimization, the material of described homogenizing plate is steel plate, and because the flue-gas temperature flowing through variable cross-section flue is higher, homogenizing plate adopts high temperature resistant, fire-resistant, under high-abrasive material ensures good water conservancy diversion prerequisite, makes operation more reliable, effectively extends the service life of equipment simultaneously.
As preferably, the quantity that described homogenizing plate is arranged is not less than 2, effectively increases water conservancy diversion effect.
Compared with prior art, the beneficial effects of the utility model are: the utility model can realize the water conservancy diversion to variable cross-section flue well, ensure the superperformance of boiler; Structure is simple, practical, and it is convenient to change, and reliable, maintenance cost is low.
Accompanying drawing explanation
The utility model illustrates by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is main structure schematic diagram of the present utility model.
Mark in figure: variable cross-section flue 1 and homogenizing plate 2.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1, as shown in fig. 1, the utility model is a kind of variable cross-section flue flow equalizing plate structure, comprises variable cross-section flue 1 and homogenizing plate 2; Described variable cross-section flue 1 cross section is horizontally disposed with splayed homogenizing plate 2.The variable cross-section flue 1 that described homogenizing plate 2 is arranged at flue gas flow direction exports, and is that herringbone is arranged along flow of flue gas direction; The angle of described homogenizing plate about 2 two interblock is arranged at by variable cross-section flue 1 angle that flue collector opens and determines, angle is larger, and angle is larger.
Embodiment 2, the basis of embodiment 1 is optimized design to the material of homogenizing plate 2, and the material of described homogenizing plate 2 is steel plate, and homogenizing plate 2 adopts high temperature resistant, fire-resistant, and high-abrasive material is made; Because the flue-gas temperature flowing through variable cross-section flue is higher, homogenizing plate adopts high temperature resistant, fire-resistant, under high-abrasive material ensures good water conservancy diversion prerequisite, makes operation more reliable, effectively extends the service life of equipment simultaneously.
Embodiment 3, decision design is carried out to the quantity that homogenizing plate 2 is arranged in the basis of embodiment 1 or embodiment 2, and the quantity that described homogenizing plate 2 is arranged is not less than 2, effectively increases water conservancy diversion effect.The quantity that homogenizing plate is arranged is determined by the cross-sectional area of variable cross-section flue when using, and cross-sectional area is larger, and the quantity that homogenizing plate 2 is arranged is more.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
Claims (3)
