Abstract

The utility model relates to a bridge-shaped fixed-valve tray deck which belongs to the technical field of components of a chemical engineering tray. The bridge-shaped fixed-valve tray deck comprises a tray deck which is provided with paired valve holes and a bridge-shaped fixed valve, first serrated gaps which are arranged at intervals each other are arranged at two lateral sides of the valve holes, and second serrated gaps which are corresponding to the first serrated gaps are arranged at two lateral sides of the bridge-shaped fixed valve. The fixed-valve tray deck can not only improve the specific surface area at the bridge-shaped fixed-valve and the valve holes, but also ensure the gas phase flow at the bridge-shaped fixed-valve and the valve holes to be distributed to be evener so as to be convenient to disperse the liquid phase, thereby improving the mass transfer efficiency between the bridge-shaped fixed valve and the gas-liquid phase at the valve holes and the whole tray deck.

Description

Bridge shape Glitsch V-O tray plate

Technical field

The utility model relates to a kind of member-tray deck of chemical industry plate column, and especially a kind of tray deck that has bridge shape standing valve structure belongs to chemical industry tower tray component technology field.

Background technology

Tray deck is the important component in the chemical industry plate column, and its pattern development is existing so far a lot.Recently very fast a kind of tray deck of using is punching out bridge shape directional fixed valve and the bridge shape Glitsch V-O tray plate that forms on tray deck, as shown in Figure 1, on tray deck 1 in pairs punching out go out to give prominence to tray deck 1 and curve the standing valve 2 (cross section is bridge shape) and the valve opening 3 of bridge shape.This bridge shape Glitsch V-O tray plate structure is simple, to air-flow lead, pressure drop is little, mass-transfer efficiency height on the plate.

But put into practice discovery according to the applicant, when this bridge shape Glitsch V-O tray plate uses, gas phase upper punch speed is fast, little at bridge shape standing valve and valve opening place and liquid phase contact-making surface, and the mobile skewness of gas phase, therefore at the gas-liquid interphase mass transfer weak effect at bridge shape standing valve and valve opening place, influence mass-transfer efficiency on the whole tray deck.

The utility model content

The technical problems to be solved in the utility model is: propose a kind of bridge shape Glitsch V-O tray plate, this bridge shape Glitsch V-O tray plate can improve the specific area and the mass-transfer efficiency at bridge shape standing valve or valve opening place, thereby further improves the mass-transfer efficiency on the whole tray deck.

The technical scheme that the utility model proposes is: a kind of bridge shape Glitsch V-O tray plate, comprise tray deck, and described tray deck is shaped on paired valve opening and bridge shape standing valve, and the dual-side of described valve opening is shaped on the first profile of tooth breach of each interval.

Improvement of the technical scheme is: the dual-side of described bridge shape standing valve is shaped on the second profile of tooth breach of the corresponding first profile of tooth breach.

Bridge shape Glitsch V-O tray plate of the present utility model is compared existing bridge shape Glitsch V-O tray plate, because the dual-side of the periphery of valve opening and bridge shape standing valve all is shaped on the profile of tooth breach of each interval on the tray deck, therefore can improve the specific area at bridge shape standing valve and valve opening place, but also the gas phase flow at this two place is more evenly distributed, help disperseing liquid phase; Thereby raising valve opening place gas-liquid is alternate and the mass-transfer efficiency of whole tray deck.

The specific embodiment

Embodiment

The bridge shape Glitsch V-O tray plate of present embodiment such as Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, comprise tray deck 1, tray deck 1 upper punch is shaped on the rectangle valve opening 3 of bridge shape standing valve 2 and corresponding bridge shape standing valve 2, has only reflected the part of tray deck 1 and part (four pairs) bridge shape standing valve 2, rectangle valve opening 3 among the figure.Be shaped on the first triangular tooth breach 4 of each interval at the dual-side of rectangle valve opening 3.

The second triangular tooth breach, 5, the second triangular tooth breach 5 and the first triangular tooth breach 4 that the dual-side of bridge shape standing valve 2 is shaped on the corresponding first triangular tooth breach 4 stagger each other.

Obviously, the bridge shape Glitsch V-O tray plate of present embodiment increases the specific area at this two place by changing the single linear profile at existing bridge shape standing valve edge and corresponding valve opening edge.When gas phase during from the second triangular tooth breach 5 of the first triangular tooth breach 4 that passes through down rectangle valve opening 3 dual-sides and bridge shape standing valve 2 dual-sides, not only can increase contact-making surface with liquid phase, but also the vapor phase stream amount is more evenly distributed, help disperseing liquid phase, thereby the mass-transfer efficiency between the raising gas-liquid two-phase, and then improve the mass-transfer efficiency of whole tray deck.

Bridge shape Glitsch V-O tray plate of the present utility model is not limited to the described concrete technical scheme of the foregoing description, such as: 1) the profile of tooth breach also can be rectangle, trapezoidal or other shape; 2) bridge shape standing valve 2 and bar shaped valve opening 3 can be selected one and be shaped on the profile of tooth breach, needn't be shaped on the profile of tooth breach simultaneously; 3) rectangle valve opening 3 also can be trapezoidal or other shape; Or the like.The technical scheme that all employings are equal to replacement or equivalent transformation formation is the protection domain that the utility model requires.
