Description
Technical field
The present invention relates to the Geldart-D particle powder flow rate control apparatus that a kind of bilateral baffle plate is adjustable.
Background technology
Geldart-D particle is a kind of effective ways utilizing air-flow conveying granular solid in the duct, and be widely used in the conveying of the powder of various industrial sector, such as, in thermal powerplant, solid fuel is as the Cemented filling of coal dust etc.
For coal burning boiler, First air manage-style powder divides balancing to have material impact for the stability of boiler operatiopn, economy, safety and the feature of environmental protection.Primary wind and powder distributes inequality can make furnace flame center that deflection occurs, and causes the too high and combustion pulsation of temperatures at localized regions in burner hearth.This not only can cause combustion instability, inboard wall of burner hearth slagging scorification, even causes the serious harm of superheater over temperature booster.The uneven combustion efficiency namely reducing boiler that wind powder distributes, turn increasing growing amount, is safe operation of power plant and energy-saving and emission-reduction urgent problem.
At present, primary air piping resistance regulates and lacks flexible, actv. device.At present, most of power plant adopts the method for cold conditions leveling to solve this problem, that is: in each First air pipeline, adjustable contraction is installed, by regulating the opening diameter size of each adjustable contraction to regulate each primary air piping resistance of ducting in the cold conditions situation of pure wind flow, thus the distribution of each First air manage-style powder is made to reach balanced.
But traditional adjustable contraction is not regulate the optimal device of the primary air piping resistance of ducting.Mainly there is following problem in traditional adjustable contraction.
1., after being with powder to run, adjustable contraction opening diameter cannot adjust neatly.
The size of cutoff port is determined according to the in-place test under pure stream condition, by in-place test determination cutoff port opening diameter size, needs wind speed in repeated measurement pipe.After band powder runs, cutoff port cannot adjust further.Research shows, even if cold conditions leveling reaches good effect, in hot situation, still there will be very large deviation.Conventional tunable shrinkage cavity cannot adjust flexibly and effectively when being with powder to run, thus can not play good regulating effect.
2. the impact of Conventional tunable shrinkage cavity on coal dust flow pattern is bad.
Aperture diminishes in the place that pipeline is suitable by traditional adjustable contraction, and when fluid flows through reducing, a fluid stream can attenuate or shrink, thus plays the effect regulating the resistance of ducting and flow velocity.But this regulative mode causes very large impact by coal dust flow pattern, what cause coal dust to flow is uneven.
3. Conventional tunable shrinkage cavity structure space is excessive, dumb.
Conventional tunable shrinkage cavity adopts bilateral straight cutting baffle plate, and structure space is large, and actual industrial scene does not many times have enough spaces to install Conventional tunable shrinkage cavity device.
4. Conventional tunable shrinkage cavity is easily piled up coal dust and is caused jam.
Conventional tunable shrinkage cavity adopts bilateral straight cutting baffle plate, and baffle plate vertical pipe, powder is easily deposited in baffle plate gap, causes jam.
Summary of the invention
For solving the problems referred to above that prior art exists, the object of this invention is to provide the Geldart-D particle powder flow rate control apparatus that a kind of bilateral baffle plate is adjustable, still can effectively regulate primary air piping to adjust flow velocity along journey resistance to flow flexibly when being with powder to run, thus realize the object that primary wind and powder divides balancing and then reach Optimizing Combustion, energy-saving and cost-reducing and decreasing pollution thing discharge.
For realizing object of the present invention, the present invention by the following technical solutions:
The Geldart-D particle powder flow rate control apparatus that a kind of bilateral baffle plate is adjustable comprises flange, pipeline arc, upper adjustable baffle plate, lower adjustable baffle plate, turning cylinder, actuating unit and seal casing shell; It is characterized in that: described upper controllable register and lower controllable register all can independently in 0 to 90 degree rotate.
Gasket set is provided with between described turning cylinder and seal casing shell; Described seal casing shell windward side is provided with liner plate windward.
Described bilateral adjustable baffle plate by actuating mechanism controls rotational angle, controls the flow area of pipeline by turning cylinder, changes the resistance of ducting, to reach the object of multi-pipeline flow velocity equilibrium in technical application.Think that rotational angle is 0 degree when bilateral adjustable baffle plate convection cell is unobstructed, think that rotational angle is 90 degree when the stop of bilateral adjustable baffle plate convection cell is maximum.The stop area of adjustable baffle plate convection cell accounts for the long-pending 0-80% of pipeline section.
Described pipeline arc, adjustable baffle plate, turning cylinder, windward liner plate are made by wear-resistant steel, and wherein pipeline arc has ceramic-lined, the wear resisting property of intensifier; Described adjustable baffle plate vertical section is orthogonal, arc or fold-line-shaped.
Compared with prior art, the present invention has the following advantages:
(1) when being with powder to run, bilateral adjustable baffle plate can be rotated by 0-90 degree in pipeline, and its resistance can consecutive variations and the linearity is better.Thus can regulate continuously the resistance of ducting neatly when being with powder to run, thus it is more even that each First air manage-style powder can be made to distribute, and burning is optimized.
(2) upper and lower side adjustable baffle plate all can freely control, and can effectively regulate primary wind and powder to distribute, and after regulating, fluid is closer to pipeline center, reduces the erosive wear to duct wall.When upside flow velocity concentration is larger, only need upper rotation angle degree to tune up; Instantly, when effluent speed concentration is larger, only need lower rotation angle degree to tune up.
(3) compared with Conventional tunable shrinkage cavity, the present invention adopts the fender plate that can rotate in baffle plate storehouse well to solve a difficult problem for powder jam.
(4) the bilateral fender plate that the present invention adopts rotates in seal casing shell, has the feature of compact structure, flexible operation, well can adapt to industry spot and install.
