Abstract
The utility model discloses a plate type wing valve of a gas-solid cyclone separation system, which is mainly used for a catalytic cracking and catalytic pyrolysis device for petrochemical works. The utility model is composed of a valve body, a hinge, a valve port and a valve plate. In order to solve the problems of abrasion resistance and sealing, the valve port of the plate type wing valve of the utility model is provided with an abrasion resistant layer in an annular elliptical plane structure, and the abrasion resistant layer is tightly compounded on the valve port; at the same time, the valve plate is provided with a corresponding projected abrasion resistant layer in an annular elliptical plane structure. Two abrasion resistant layers are hard alloy layers or abrasion resistant powder layers, having good abrasive resistance. Because the abrasion resistant layers in the structures and the shapes, the plate type wing valve of the utility model has good abrasion resistance and sealing performance, so that the service lives of the plate type wing valve and the whole cyclone separation system can be prolonged, the efficiency of the cyclone separation system is guaranteed and the loss of catalyst is reduced.
Description
Technical field
The utility model belongs to gas-solid separation equipment.A kind of cyclone separation system equipment that is used for gas solid separation of more specifically saying so is mainly used in the cyclone separation system of petrochemical industry catalytic cracking and cat-cracker.
Background technique
Gas solid separation is exactly the technology that powder is separated from the mixture of gas and powder.Utilizing cyclone separation system to carry out gas solid separation is one of effective ways.The cyclone separation system of catalytic cracking and cat-cracker is normally by cyclone separator, dipleg and the board-like flutter valve of mounting arrangements are formed from top to bottom.Cyclone separator plays the gas solid separation effect, and dipleg plays and utilizes the effect of material level balance external pressure, and board-like flutter valve then plays discharge and sealing.Promptly when powder reached certain altitude in the dipleg, flutter valve was opened; And after the powder emptying, will close and seal.The purpose of sealing is because system's external pressure greater than internal system pressure, if the sealing of board-like flutter valve is bad, just has gas and enters dipleg and cyclone separator by board-like flutter valve, and then influence separation effect.
Board-like flutter valve is made up of valve body, valve port, valve plate and hinge, as shown in Figure 1.Its working principle is to utilize the gravity horizontal component of inclination valve plate that valve port is carried out shutoff; when the solid powder/particle in the valve body runs up to a certain degree; will push valve plate open and carry out discharging, will divide equally under the power effect at the gravitational water of valve plate after discharging finishes and close automatically, realize sealing.
Existing board-like flutter valve is not owing to have wearing layer at valve plate and valve port position easy to wear, in operating process owing to constantly be subjected to the erosion of solid catalyst powder, on valve port and valve plate, cause wearing and tearing easily, make the valve port and the valve plate of flutter valve poorly sealed, thereby cause that extraneous gas scurries into valve body when flutter valve is closed, enter cyclone separator, reduce the efficient of cyclone separator, and cause the loss of catalyzer to increase.
Summary of the invention
Purpose of the present invention just is by setting up the wearing layer of a specified structure and shape at valve port and valve plate position easy to wear, increase its wear resistance, have the not wear-resisting problem of board-like flutter valve now to solve, thereby prolong its working life, guarantee the efficient of cyclone separator, reduce the loss of catalyzer.
In order to achieve the above object, the technical solution adopted in the utility model is: this board-like flutter valve is made up of valve body, hinge, valve port and valve plate, at the wearing layer that has the ring elliptic plane structure that closely is compounded on the valve port on the valve port; On valve plate, have simultaneously accordingly, wearing layer protrusion, ring elliptic plane structure, and the two can fit tightly together the maintenance excellent sealing performance.
The utility model is owing to adopt the wearing layer of said structure shape at the contact area of valve plate and valve port, can increase substantially the wear resistance of board-like flutter valve, guarantee the sealing of board-like flutter valve, thereby can prolong the life-span of board-like flutter valve and whole cyclone separation system, and reduce the loss of catalyzer.
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.

Embodiment
As shown in Figure 1, the board-like flutter valve of the utility model is made up of valve body 1, hinge 2, valve port 3 and valve plate 4.As Fig. 2 and shown in Figure 4, on valve port 3, has the wearing layer 5 of the ring elliptic plane structure that closely is compounded on the valve port; As Fig. 3 and shown in Figure 5, on valve plate 4, has accordingly wearing layer 6 protrusion, ring elliptic plane structure simultaneously.Valve port wearing layer 5 and valve plate wearing layer 6 are hard alloy layer or wear-resisting powder layer; The thickness of valve port wearing layer 5 and valve plate wearing layer 6 is 0.05～2 millimeter.
The wearing layer of valve port wearing layer 5 and valve plate wearing layer 6 adopts plasma spray technologies such as existing ripe plasma, flame spraying, or various technique for overlaying, or the Clad Steel Plate technology is made.
