Abstract
The invention relates to a long-strip-shaped float valve and belongs to the technical field of chemical equipment for gas-liquid mass transfer separation in the chemical industry. The float valve comprises a quadrangular valve cover and two valve legs and is characterized in that an embossment high in the middle and low in the periphery is formed in the bottom of the valve cover; at least one tongue hole is formed in the valve cover; an obliquely arranged baffle is arranged at the tongue hole of the top of the valve cover; teeth are arranged on two opposite sides of the valve cover; the valve legs are arranged at the bottom of the valve cover, close to the other two sides; the valve legs are perpendicular to the valve cover; a valve foot is arranged at the lower end of each valve leg; a corrosion resistant coating coats the outer surface of the float valve. According to the float valve, the gas-liquid contact area can be effectively enlarged and the mass transfer efficiency can be improved.
Description
Technical field
The present invention relates to a kind of float valve, belong to the technical field of chemical that in chemical industry, gas-liquid mass transfer is separated.
Background technology
Plate column is a class for the classification contact mass transfer equipment of gas-liquid or liquid liquid system, by cylindrical-shaped tower and at a certain distance the some column plates of horizontal device in tower form.Be widely used in rectifying and absorption, also can be used as reactor for liquid phase course of reaction.During operation, liquid under gravity, flows through each layer column plate from top to bottom successively, discharges at the bottom of tower; Gas, under pressure differential promotes, from bottom to top successively through each layer column plate, is discharged to tower top.Every block column plate remains the liquid layer of certain depth, gas is distributed in liquid layer by column plate and goes, and carries out phase border contact mass transfer.
Column plate is the position of gas-liquid two-phase contact mass transfer in plate column, and determine the operating characteristics of tower, float valve is the gas phase dispersion component on valve plate; Can float on column plate, change its open degree along with the change of gas flow.
F1 type (also claiming V1 type) valve plate is the most frequently used column plate, but production practices show, in use there is following problem in F1 type float valve: (1) is because on column plate, liquid level is different everywhere, when causing float valve to be blown afloat, each float valve is by time of blowing open and caused by the degree varies blown open; (2) air-flow is blown into liquid layer from valve opening surrounding, does not have guidance quality, and liquid foam entrainment increases, and plate efficiency reduces; (3) air pocket bloated from valve opening effectively can not be smashed refinement, makes liquid phase contact mass transfer area little, affects the raising of mass-transfer efficiency; (4) float valve wear phenomenon is serious, and is easy to come off.
Summary of the invention
The technical problem that the present invention solves is: propose a kind of a kind of float valve that can increase mass-transfer efficiency for the deficiencies in the prior art.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of rectangle float valve, comprise valve gap and two valve legs of quadrangle, described valve gap is at least provided with a tongue apertures, described valve gap top is provided with the baffle plate be obliquely installed at tongue apertures place, two relative sides of described valve gap are provided with tooth, strip bulge is provided with in surrounding bottom described valve gap, described projection is provided with multiple hole, described valve leg is arranged on bottom valve gap near another two side edge, described valve leg is vertical with valve gap to be arranged, the lower end of described valve leg is provided with valve pin, described float valve outer surface is provided with corrosion-resistant finishes.
Being improved to technique scheme: described valve gap is rectangle, the ratio of its long limit and minor face is 2:1, and described tooth is arranged on two long edge positions of valve gap.
Being improved to technique scheme: described tongue apertures has two.
Being improved to technique scheme: described baffle plate and valve gap angle are 20 ° to 30 °.
Being improved to technique scheme: bend bottom described teeth directional valve gap.
Being improved to technique scheme: described corrosion-resistant finishes is the coating containing carbamide paint or polyurethane.
Beneficial effect of the present invention is: (1) valve gap is provided with tongue apertures, and when gas velocity is lower, valve gap is closed, and gas sprays by tongue apertures, and bubbling is steady, can reduce float valve vibration; (2) two sides of valve gap are provided with tooth, be separated into much tiny air-flow, reduce the diameter of bubble when gas is bloated, and increase gas liquid interfacial area, and mass-transfer efficiency increases; (3) be provided with strip bulge in surrounding bottom valve gap, described projection is provided with multiple hole, time the segmentation of air-flow first through hole before bloating valve gap, reduce the diameter of bubble, increase gas liquid interfacial area, mass-transfer efficiency increases; (4) float valve outer surface is provided with corrosion-resistant finishes, extends the service life of float valve.
