Description
Technical field
The utility model belongs to gas-solid separation equipment technical field, relates to a kind of Effect of Catalysis In Petrochemistry cracking unit cyclone dip-leg outlet flutter valve, is specifically related to a kind of double-open type valve plate wing valve.
Background technique
The effect of cyclone dip-leg lower exit flutter valve is concentration and the reserve of catalyzer in stable dipleg, Negative Pressure Difference between balance dipleg inside and the outside discharge space of flutter valve, there is unidirectional discharge and avoid gas anti-channeling to enter the function of dipleg, to ensure the normal running of cyclone separator.The performance of flutter valve directly has influence on the security of operation of cyclone separator and catalytic cracking unit.
The mass flowrate size of cyclone dip-leg catalyst particles highly produces material impact to material envelope in dipleg.When the particle mass flux of blanking is lower, can not sets up and effectively expect envelope, or discharging process forms semicanal discharge, result in flutter valve discharge upper space and open wide formation anti-channeling gas, anti-channeling gas carries the problem that particle causes valve plate erosive wear.The wearing and tearing of flutter valve often cause cyclone separator operation exception or inefficacy, affect catalytic cracking unit long period safe and stable operation.Therefore, the wear problem solving flutter valve is the key factor of assurance device long period safe operation.
The patent No. is that the Chinese patent of ZL 201010562496.3 discloses a kind of folding valve plate wing valve, a traditional monoblock valve plate is divided into upper and lower two pieces of valve plates, articulated manner is adopted to connect between two pieces of valve plates, the valve plate wear problem caused with the change adapting to dipleg inner catalyst mass flowrate.But owing to being hinged between upper and lower two pieces of valve plates, lower valve plate is hinged on the lower edge of valve plate, upper valve plate connects with the davit be fixed on valve body and suspension ring, upper and lower two pieces of valve plates still form an entirety and can not freely rotate completely alone, there is certain interlock interference mutually, the rotation of lower valve plate still can cause certain adverse effect to the sealing of upper valve plate.
Model utility content
The purpose of this utility model is to provide a kind of double-open type valve plate wing valve, eliminate the air intake gap of anti-channeling gas, to alleviate because anti-channeling air-flow carries the erosive wear to flutter valve valve plate that catalyst granules causes, extend the working life of flutter valve, improve the service behaviour of cyclone dip-leg.
The utility model double-open type valve plate wing valve, comprises valve plate, lower valve plate, suspension ring, davit and valve body, and davit is weldingly fixed on valve body, and upper valve plate is located on davit by suspension ring hanging.Wing body is provided with hinge and free bearing, and hinge is fixed on the both sides of lower valve plate, and free bearing is weldingly fixed on the both sides of valve body discharge port, and lower valve plate connects location by hinge and free bearing, and freely rotates with hinge.The cutting lines of upper valve plate and lower valve plate is between 1/3 to 2/3 of whole valve plate height.
Upper valve plate with between lower valve plate for overlapping mode connects, the connection place of upper valve plate is concave circular arcs face, and the connection place of lower valve plate is convex shaped arc face, and the center of circle of hinge center line and lower valve plate convex shaped arc is on the same axis.When upper valve plate and lower valve plate close, the edge of two valve plates exceeds discharge port edge 10 ~ 70mm.When flutter valve is in closed state, the mounting inclination angle degree of upper valve plate, lower valve plate and vertical direction is 3 ° ~ 8 °.Upper valve plate, lower valve plate freely rotate alone, do not interfere with each other mutually.There is single open-type and double-open type discharge function.
When catalyst granules mass flowrate is smaller, only open lower valve plate, upper valve plate is closed prevents air-flow anti-channeling.When catalyst granules mass flowrate is larger, upper and lower valve plate full open, mutually noiseless between upper and lower valve plate, there is double-open type valve plate discharge function, the aperture of upper and lower two valve plates is fixed with the catalyst granules mass flowrate size acted on thereon, can alleviate the erosive wear of Dual-Phrase Distribution of Gas olid to valve plate.
The utility model double-open type valve plate wing valve, by increasing hinge and free bearing at valve body discharge port, makes lower valve plate freely rotate alone, does not interfere with each other mutually.Upper valve plate and lower valve plate can perform closure or openness operation respectively, dipleg is exported and is in single open-type or double-open type two kinds of discharge serviceability, prevent air-flow anti-channeling, be conducive to alleviating catalyst granules that anti-channeling air-flow carries to the erosive wear of valve plate, extend the working life of flutter valve, improve the service behaviour of cyclone separator.The utility model structure is simple, and fabricating cost is lower, is applicable to FCC unit cyclone dipleg flutter valve, is also applicable to other gas solid separation cyclone dip-leg.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in detail.The utility model protection domain is not limited to embodiment, and those skilled in the art make the scope that any change also belongs to the utility model protection in the scope that claim limits.
The utility model double-open type valve plate wing valve as shown in Figure 1 and Figure 2, comprises valve plate 1, lower valve plate 2, suspension ring 5, davit 6, hinge 3, free bearing 4 and valve body 7.Davit 6 is weldingly fixed on valve body 7, and upper valve plate is hung on davit by suspension ring.Hinge 3 is located at the both sides of lower valve plate 2, and free bearing 4 is weldingly fixed on the both sides of valve body 7 discharge port, and lower valve plate connects location by hinge 3 and free bearing 4, and freely rotates with hinge.The cutting lines of upper valve plate and lower valve plate is positioned at 1/2 place of whole valve plate height.As shown in Figure 3, upper valve plate 1 with between lower valve plate 2 for overlapping mode connects, the connection place of upper valve plate 1 is concave circular arcs face.The connection place of lower valve plate 2 is convex shaped arc face, and the center of circle of hinge 3 center line and lower valve plate convex shaped arc on the same axis.When upper valve plate 1 and lower valve plate 2 close, the edge of two valve plates exceeds discharge port edge 20mm.When flutter valve is in closed state, the mounting inclination angle degree of upper valve plate, lower valve plate and vertical direction is 5 °.
Conventional whirlwind shunt dipleg flutter valve monoblock valve plate is divided into upper and lower two-part by the utility model, and the coercive mechanism of each valve plate is all fixed on valve body, can freely rotate alone and not interfere with each other between the two, forms double-open type valve plate.When the catalyst granules mass flowrate in cyclone dip-leg is lower, as shown in Figure 4, the lower valve plate of flutter valve is open, and upper valve plate closes.Catalyst granules now in dipleg is mainly discharged from lower valve plate opening, and upper valve plate is in closed state, and seal is better, can not form the gap of anti-channeling air-flow.When the catalyst granules flow rate in cyclone dip-leg is larger, as shown in Figure 5, the upper valve plate of flutter valve and lower valve plate are opened simultaneously, the opening angle of two valve plates is fixed with the size of effect catalyst granules mass flowrate thereon, catalyst granules in dipleg is discharged from upper lower valve plate opening full packages, namely form double-open type valve plate discharge, anti-channeling air-flow can not be formed.Double-open type valve plate can according to the size variation of particle mass flux, automatically single open-type discharge and double-open type discharge is taked, eliminate the air intake gap of anti-channeling gas, alleviate anti-channeling air-flow and carry the erosive wear of catalyst granules to valve plate, ensure that the normal running of cyclone system.
