Abstract
The utility model relates to a fixed valve tray deck which belongs to the technical field of components of chemical engineering tray. The fixed valve tray deck comprises a tray deck provided with valve holes and a fixed valve corresponding to the valve holes, wherein the fixed valve is provided with a support leg which is fixed with the tray deck; and serrated gaps which are arranged at intervals each other are arranged at the peripheries of the valve holes. The fixed valve tray deck can not only improve the specific surface area at the valve holes, but also ensure the gas phase flow to be distributed to be evener so as to be convenient to disperse the liquid phase, thereby improving the mass transfer efficiency between the gas phase and the liquid phase at the valve holes and the whole tray deck.
Description
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 the 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 valve tower plate wherein is present widely used a kind of tray deck.But the float valve of valve tower plate produces in when work and rotates erratically and play up and down, therefore develops out a kind of float valve to be fixed in Glitsch V-O tray plate on the tray deck.The common structure of this Glitsch V-O tray plate generally is corresponding standing valve place's punching out valve opening on tray deck, and standing valve is fixed by supporting leg and tray deck; During use, the gas phase of rising by valve opening after in standing valve guiding and under distributing with tray deck on liquid phase carry out mass transfer.
According to the knowledge of the applicant, the valve opening of punching out generally all is simple circular and square on the existing Glitsch V-O tray plate.Like this, gas phase is fast in valve opening place upper punch speed, little with the liquid phase contact-making surface, and the gas phase skewness that flows, therefore at the gas-liquid interphase mass transfer weak effect at valve opening place.
The utility model content
The purpose of this utility model is: propose a kind of Glitsch V-O tray plate, this Glitsch V-O tray plate can improve the specific area at valve opening place, and then improves gas-liquid interphase mass transfer efficient.
In order to reach above aforementioned purpose, the solution that the utility model proposes is: a kind of Glitsch V-O tray plate comprises the tray deck that is shaped on valve opening and the standing valve of corresponding valve opening, the supporting leg that described standing valve is shaped on and tray deck is fixing; The periphery of described valve opening is shaped on the profile of tooth breach of each interval.
Glitsch V-O tray plate of the present utility model is compared existing Glitsch V-O tray plate, because the periphery of the valve opening on the tray deck is shaped on the profile of tooth breach of each interval, therefore can improve valve opening place specific area, but also the vapor phase stream amount 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.
Description of drawings
Fig. 1 is the partial structurtes generalized section of the utility model embodiment one Glitsch V-O tray plate.
Fig. 2 is the upward view of Fig. 1.
The specific embodiment
Embodiment
The Glitsch V-O tray plate of present embodiment comprises tray deck 1 and circular standing valve 2 as depicted in figs. 1 and 2, is shaped on circular valve opening 3 (only having reflected the part of tray deck 1 and partial fixing valve 2, valve opening 3 among the figure) on the tray deck 1.Standing valve 2 corresponding circular valve openings 3 also are shaped on two supporting legs 4, and supporting leg 4 passes circular valve opening 3 and is fixed on the bottom surface of tray deck.Be shaped on the first triangular tooth breach 5 of each interval in the circumferential edge of circular valve opening 3.
The top perimeter of standing valve 2 is shaped on second triangular tooth breach 6, the second triangular tooth breach 6 and the first triangular tooth breach 5 relative with the first triangular tooth breach 5 and staggers each other.
In use, the Glitsch V-O tray plate of present embodiment is owing to gas phase during from the following first triangular tooth breach 5 by circular valve opening 3 circumferential edge, can increase contact-making surface with liquid phase, and the vapor phase stream amount is more evenly distributed, help disperseing liquid phase, thereby improve the mass-transfer efficiency between the gas-liquid two-phase.Subsequently, when gas phase is also passed through the second triangular tooth breach 6 at the top that arrives standing valve 2, can increase the contact-making surface of gas phase again, thereby further improve the mass-transfer efficiency between the gas-liquid two-phase in standing valve 2 tops and liquid phase.
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, understand easily: 1) standing valve 2 and valve opening 3 also can be rectangle, trapezoidal or other shape; 2) the concrete pattern of standing valve 2 can adopt float valves such as F1 type, stripe shape, V-type and T type are fixed in pattern on the tray deck; 3) standing valve 2 and supporting leg 4 also can be to make with tray deck 1 disjunctor, form as whole punching out on tray deck 1; 4) supporting leg 4 numbers also can be one or more; 5) the profile of tooth breach also can be rectangle, 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.
