Embodiment 1

[0033] like figure 1 As shown, a new type of tray with a large flux of gas-liquid evenly distributed, including tray 2, valve hole 3 and float valve 1; float valve 1 includes valve plate 11, valve leg 12 and spacer bar 13; wherein the valve plate 11. The edges are alternately arranged with convex arcs and concave arcs. There are three convex parts 14 formed by convex arcs and three concave parts 15 formed by concave arcs. The three convex parts 14 have the same radius of curvature, and the three concave parts 15 The radii of curvature are the same, and the radii of curvature of the three convex portions 14 are less than or equal to the radii of curvature of the three concave portions 15, (preferably the radius of curvature of the convex portions 14 is equal to the radius of curvature of the concave portion 15); between valve plates 11 of different float valves 1 The concave part 15 and the convex part 14 can cooperate with each other; the edge of the valve plate 11 can be incl...

Embodiment 2

[0040] Different from Example 1, as figure 2 As shown, the valve plate 11 can be provided with one or more guide holes 18, and the guide hole 18 is fixed with a guide valve plate 110 supported obliquely. The edge shape of the guide valve plate 110 corresponds to the edge shape of the guide hole 18. ; The guide hole 18 is tongue-shaped, trapezoidal, rectangular, circular or triangular, and the guide valve plate 110 and the guide hole 18 are made by stamping directly on the valve plate.

Embodiment 3

[0042] In the specific embodiment of the present invention, the fixed valve tray of the same structure can also be used, a kind of fixed valve tray, including tray, valve hole and fixed valve; The convex arcs and concave arcs are arranged alternately, and there are three convex parts formed by the convex arcs and three concave parts formed by the concave arcs. The curvature radii of the three convex parts are the same, and the curvature radii of the three concave parts are the same, and The radius of curvature of the convex part is less than or equal to the radius of curvature of the concave part, preferably the radius of curvature of the convex part is the same as that of the concave part; there are three valve legs, and the valve legs are equidistantly spaced, one end of the valve leg is fixed on the lower end surface of the convex part, and the other end is fixed to the tray connect.

[0043] There are several rows of fixed valves parallel to each other on the tray; the fix...

Abstract

The invention provides a novel high-flux gas-liquid uniform tower tray which comprises a tower plate, valve openings and floating valves. The edge of the valve block of each floating valve is arranged in a manner that convex arches and concave arches are arranged in intervened arrangement, the number of convex portions formed by the convex arches and the number of concave portions formed by the concave arches are respectively three, and the curvature radius of the convex portions is smaller than / equal to that of the concave portions; valve legs of each floating valve are perpendicularly fixed on the lower end surface of each convex portion, and the number of the valve legs is three which are in equidistant interval distribution; a spacing strip is arranged at the edge of each valve block. The novel high-flux gas-liquid uniform tower tray is high in operational flexibility, high in mass transfer efficiency, even in airflow dispersion and sufficient in gas-liquid connection.

Description

technical field [0001] The invention belongs to the field of internal components of tower equipment, and in particular relates to a novel tower tray. Background technique [0002] Tower equipment is an important unit operation equipment in the chemical industry, oil refining, food, medicine and environmental protection and other departments. The tower equipment makes the gas phase and the liquid phase fully contact to achieve the purpose of mass transfer and heat transfer between phases. For the plate tower For the purpose, the core component to achieve this purpose is the tray. The tray is the main gas-liquid and liquid-liquid contact element. The performance of the tray not only affects the performance and quality of the product, but also affects the economic benefit, energy consumption, output value and environment. [0003] The forms of existing trays mainly include: sieve trays, bubble cap trays, valve trays and various through-flow trays. The elasticity is small; the...
