Problems solved by technology

When the floating valve is fixed on the tray, it is a fixed-valve tray, which overcomes the common disadvantages of the traditional fixed-valve tray, such as: material back-mixing, large liquid level gradient and resistance, and dead zone and stagnation zone phenomenon; The float valve is connected to the tray by floating clips and used as a composite tray with the float valve reinforced valve, which overcomes the problem that the traditional float valve is easy to block

Abstract

The invention discloses a floating valve which comprises an inverted V-shaped floating valve element. An isosceles triangular plate is bent along the center line of a bottom edge to form the floatingvalve element, and the floating valve element comprises a ridge beam and triangles, an inclination angle is formed between the ridge beam and a horizontal plane. A hinge is arranged at the front end of the floating valve element, and a fixing valve rod is arranged at the rear end of the floating valve element. Inclined sawteeth are arranged on two middles of the isosceles triangular plate to formtoothed wing grooves, and the tips of the inclined sawteeth are inclined towards the tail end of the floating valve element. The invention further discloses a rectifying column tray with the floatingvalve. Two rows of adjacent floating valves are staggered, the projection of the ridge beam of at least one floating valve of at least one end of each row of floating valves is parallel to the tangentline of a column plate, so that the floating valves at the same end are arranged in an arc-shaped mode along a column wall, and the projection of the ridge beams of the rest floating valves on the column plate is parallel to the flowing direction of liquid on the column plate. Mass transfer effects are enhanced by the floating valve, the mass transfer efficiency of the floating valve is improvedby 10% or more as compared with a traditional valve, and the problem of easiness in blockage of an existing floating valve is solved.

Description

technical field [0001] The invention relates to a gas-liquid heat and mass transfer device used in chemical distillation and separation engineering, in particular to a float valve and a rectification tray provided with the float valve. Background technique [0002] The tray is the main component structure in the plate tower, including the tray 2, the downcomer, the overflow weir 3, various valves, fasteners and supports for supporting the tray type, etc. The tray is the part that realizes heat transfer and mass transfer. There are mainly two types of valve trays and sieve trays. Valve trays occupy the majority of plate towers. The commonly used float valves in float valve trays are T-type float valves, F1-type float valves, guided float valves of East China University of Science and Technology, tongue-type solid valves, and MVG solid valves, but the mass transfer effect of the above-mentioned float valve trays is limited, especially When dealing with small gas volumes (such...
