Description
Technical field
The utility model relates to a kind of deslagging control apparatus for recirculating fluidized bed (CFB) boiler, is specifically related to a kind of butterfly valve type water-cooled slagging coutrol valve.
Background technique
At present domestic big-and-middle-sized CFB boiler generally adopts the equipment of roller slag cooler and deslagging control cooling as end slag, according to the Design Conception of roller slag cooler, the end slag of being discharged by scum pipe forms a slag muck in cinder cooling device, and the internal friction that slag muck produces stops the continuation of slag stream in pipe to be discharged; In the time being promoted lime-ash by drum rotating and move to cylinder slag output end, slag muck height declines thereupon, and the frictional force of slag muck is not enough to stop the discharge of slag stream, and in pipe, slag stream continues again; Realize the control to bed drain purge by start and stop and the rotational speed regulation of cylinder like this.Mobility due to high temperature bottom slag in practical application is very good, and the internal friction of slag muck is difficult to play " slag envelope " effect to managing interior slag stream, and end slag " gravity flow " phenomenon often occurs, and burner hearth bed is pressed and maintained difficulty.It is isolated that high temperature resistant push-pull valve (non-water-cooling type) on scum pipe is only used as pipeline, and seldom operation, also cannot control bed drain purge at ordinary times.
Summary of the invention
To be solved in the utility model is the technical problem of deslagging control in CFB boiler operatiopn, propose a kind of can be at the slag-off valve of reliable operation, deslagging regulating power excellence under high temperature condition.
The utility model is to provide a kind of butterfly valve type water-cooled slagging coutrol valve for solving the problems of the technologies described above proposed technological scheme, comprise water-cooled valve body, the both sides up and down of water-cooled valve body are respectively equipped with water-cooled valve rod, 2 water-cooled valve rod outsides are overlapped and are had upper flange, lower flange respectively, it is characterized in that, described water-cooled valve body is that Double water-cooled is jacket structured, in this Double water-cooled is jacket structured, is provided with valve plate.
Preferably, described valve plate is water-cooling type butterfly plate structure, is provided with cooling water passage in valve plate, and the import of cooling water passage and outlet are exposed from the side of valve plate.
Further, what the import of described cooling water passage and outlet were exposed with water-cooled valve rod joint any from valve plate or be connected with water-cooled valve rod from valve plate two exposes respectively, the water-cooled valve rod of this joint is hollow-core construction, is communicated with import and/or the outlet of cooling water passage.
Preferably, described water-cooled valve interior wall is provided with the seal boss matching with valve plate, and in the time that control valve is closed, the seal boss of valve plate and water-cooled valve interior wall fits tightly.
In actual motion, set slagging coutrol valve aperture initial value according to end slag flow and slag-off valve rating curve, and set the suitable rotating speed of roller slag cooler; Press while continuing to increase (or reduce) when bed, can suitably strengthen (or reducing) control valve aperture, the rotating speed of corresponding adjustment barrel slag cooler, thus realize effective control that bed is pressed and maintain the balance of the quantity of slag in cinder cooling device.Visible, water-cooled slagging coutrol valve can replace the control of roller slag cooler to bed drain purge completely, and it is more effective, reliable to control effect.
The utility model, by adopting the structures such as water-cooled valve body, water-cooled butterfly plate and water-cooled valve rod, significantly reduces the operating temperature of valve critical piece, can be under the high temperature of 900～1000 DEG C reliable operation; Aperture by water-cooled butterfly plate between 0 °～90 ° changes the function that can realize valve fast opening and closing and Flow-rate adjustment, realizes the controlled discharge of high-temperature ash.The utility model has thoroughly solved end slag " gravity flow " phenomenon in scum pipe, is conducive to the stable of boiler operating parameter.Because slagging coutrol valve critical piece is water-cooling structure, in During Process of Long-term Operation, can not deform, the problem such as bite, flexible operation, can maintain normal work for a long time.

Embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
Embodiment 1
As shown in Figure 1-2, the structural representation of the butterfly valve type water-cooled slagging coutrol valve providing for the utility model, comprise water-cooled valve body 1, the both sides up and down of water-cooled valve body 1 are respectively equipped with water-cooled valve rod 5,2 water-cooled valve rod 5 outsides are overlapped respectively upper flange 3, lower flange 4, described water-cooled valve body 1 is that Double water-cooled is jacket structured, in this Double water-cooled is jacket structured, is provided with valve plate 2.As shown in Figure 3-4, valve plate 2 is water-cooling type butterfly plate structure, is provided with snakelike cooling water passage 6 in valve plate 2, and cooling water passage 6 is uniformly distributed on valve plate 2.The import 61 of cooling water passage 6 and outlet 62 are exposed from the joint of valve plate 2 downsides and water-cooled valve rod 5.Downside water-cooled valve rod 5 is hollow-core construction, is communicated with import 61 and the outlet 62 of cooling water passage 6.Water-cooled valve body 1 inwall is provided with the seal boss 7 matching with valve plate 2, and in the time that control valve is closed, valve plate 2 fits tightly with the seal boss 7 of water-cooled valve body 1 inwall.Sealing configuration between water-cooled valve rod 5 and water-cooled valve body 1 adopts traditional control valve sealing configuration, adopts the sealing configurations such as filler, stuffing box gland, and lime-ash can be leaked to outside valve.
