Abstract
The utility model relates to a frame-type desulfurizing flue guard board air-valve, which is characterized in: The present utility model consists of a framework, two guard board blades, a keel and a sealed air passage, the two guard board blades provided in the framework in parallel, at least two keels going trough between the two guard board blades in parallel, the sealed air passage vertically provided between two guard board blades and connected with at least two air channels which are vertical to the sealed air passages, the sealed support arranged on the internal side of the framework. The present utility model has advantages of zero leakage of the air valve is ensured, the removable combination framework structure adopted and the very good integrity.
Description
Technical field
The utility model relates to a kind of frame-type desulfurization duct baffle ventilation door, is used for thermal power generation 20MW～1000MW desulfurization unit, belongs to the baffle ventilation door technical field of boiler desulfurization system.
Background technology
Desulphurization system is started late on the thermal power generation unit of China, and the experience aspect desulfurization is relatively weaker, and most equipment all adopt external import.In recent years, along with the acceleration of production domesticization, the equipment in the desulphurization system also adopted home products more and more; Home products exists many-sided problem at present: with regard to the desulfurization air door, all made by individual plates, this individual plates air door or rigidity cause distortion inadequately, or the unreasonable sealing air that causes of seal channel design can not circulate, or adopt the pasting board mode imprecision of fitting, produce and leak.
Summary of the invention
The purpose of this utility model is a kind of frame-type desulfurization duct baffle ventilation door that makes air door reach zero leakage of invention.
For realizing above purpose, the technical solution of the utility model provides a kind of frame-type desulfurization duct baffle ventilation door, it is characterized in that, form by framework, two baffle blades, keel, sealing air passages, two baffle blades are located in the framework abreast, at least two parallel traversing in the middle of two baffle blades of keel, and the sealing air channel vertical is located between two baffle blades, be connected with at least two air channels perpendicular to the sealing air passage, sealed support is located at the framework inboard.
Described framework is removable combined frame structure, and the outside is provided with floor and fagging, and material is an explosive clad plate; The material of described two baffle blades is an explosive clad plate, and the two sides is provided with corrosion-inhibiting coating; Evenly be provided with aperture on the described air channel.
The utility model adopts sealed support, a reliable sealed air system has been formed in the design of two baffle blades and sealing air passage, the framework outside has many group floors and fagging to strengthen rigidity, baffle plate assembly also has " keel " that traverse its inside and guarantees its integral rigidity, sealed support set up the adjusting of not only being convenient to diaphragm seal, and strengthened the rigidity of air door to a certain extent, adopt the compound panel of blast complex method, because the state long term exposure that blade is in out is in wet flue gas, the corrosion situation of carbon steel face is more abominable, the use of coating is in order further to strengthen the corrosion resistance of baffle plate, to adapt to diversified working environment better.The utility model has adopted the sealing air channel of sealing characteristic between set frame seal and baffle plate, and processing technology and aerodynamics are organically combined, and designs a rational sealing air passage.The sealing air duct with air by enter the cavity of whole two baffle blades perpendicular to the air channel aperture of sealing air passage, can guarantee that each sealing surface all has a pressure flow field uniformly, and reduced the whole pressure loss, the pressure of pneumatic curtain wall that guarantees each sealing surface is even, make air door reach zero leakage, and such design to allow the pressure head of seal fan descend many, saved electric energy.
The utility model has the advantages that to make air door reach zero leakage, adopt removable combined frame structure, easy accessibility, globality is fine.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, be frame-type desulfurization duct baffle ventilation door structural representation, described frame-type desulfurization duct baffle ventilation door is made up of framework 1, two baffle blades 2, keel 3, sealing air passages 4.
The material of framework 1 and two baffle blades 2 selects explosive clad plate, becomes the plate of channel-section steel shape by dull and stereotyped flanging, has constituted the skeleton of framework outside, framework up and down between cover plate and the side plate by the bolt location be welded to connect.Divide the segment frames place, by the welding then of bolt location, framework 1 outside is provided with floor and fagging, sealed support 6 is located at framework 1 inboard, has guaranteed the integral rigidity of framework, and two baffle blades 2 that the two sides is provided with corrosion-inhibiting coating are installed in 1 li of framework abreast, at least two keel 3 traverse in the middle of two baffle blades 2, sealing air passage 4 is vertically mounted between two baffle blades 2, is connected with at least two air channels 5 perpendicular to sealing air passage 4, evenly is provided with runner on the air channel 5.
During work, sealing air passage 4 with air by enter the cavity of whole two baffle blades 2 perpendicular to air channel 5 runners of sealing air passage, form a pneumatic curtain wall, can guarantee that each sealing surface all has a pressure flow field uniformly, the pressure of pneumatic curtain wall that guarantees each sealing surface is even, adds the sealing of framework 1, makes air door reach zero leakage, and such design to allow the pressure head of seal fan descend many, saved electric energy.
