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 separates.
Background technology
Plate column is a class for gas-liquid or the discrete stage contact mass transfer apparatus of liquid liquid system, by cylindrical-shaped tower and at a certain distance the horizontal device some column plates in tower form.It is widely used in rectification and absorption, is alternatively arranged as reactor for liquid phase course of reaction.During operation, liquid is under gravity, flows successively through each layer column plate from top to bottom, discharges at the bottom of tower;Gas, under pressure differential promotes, sequentially passes through each layer column plate from bottom to top, discharges to tower top.Remain the liquid layer of certain depth on every block of column plate, gas is distributed in liquid layer by column plate, carries out phase border contact mass transfer.
Column plate is the position of gas-liquid two-phase contact mass transfer in plate column, determines the operating characteristics of tower, and 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 referred to as V1 type) valve plate is the most frequently used column plate, but production practices show, F1 type float valve in use there is problems in that (1) due on column plate everywhere liquid level different, when causing float valve to be blown afloat, time that each float valve is blown open and the degree blown open are inconsistent；(2) air-flow is blown into liquid layer from valve opening surrounding, does not has 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 prone to come off.
Summary of the invention
Present invention solves the technical problem that and be: propose a kind of energy for the deficiencies in the prior art and reduce a kind of float valve rocked.
For solving above-mentioned technical problem, the technical scheme is that a kind of float valve, valve gap and two valve lower limbs including tetragon, at least provided with a tongue apertures on described valve gap, described valve gap top is provided with the baffle plate being obliquely installed at tongue apertures, and two relative sides of described valve gap are provided with tooth, described valve lower limb is arranged on bottom valve gap near another two side edge, two described valve lower limbs tilt the most laterally, and described valve lower limb is made up of elastic metallic material, and the lower end of described valve lower limb is provided with valve foot；Described float valve outer surface is provided with corrosion-resistant finishes.
Being improved to technique scheme: described valve gap is rectangle, its long limit is 2:1 with the ratio of minor face, and described tooth is arranged on two long edge positions of valve gap.
Technique scheme is improved to: described tongue apertures has two.
Technique scheme is improved to: described baffle plate and valve gap angle are 20 ° to 30 °.
Technique scheme is improved to: bend bottom described teeth directional valve gap.
Technique scheme is improved to: between described valve lower limb and valve gap, angle is 75 ° to 80 °.
Technique scheme is improved to: described corrosion-resistant finishes is the coating containing carbamide paint or polyurethane.
The invention have the benefit that (1) valve gap is provided with tongue apertures, when gas velocity is relatively low, valve gap is closed, and gas can be sprayed by tongue apertures, and bubbling is steady, can reduce float valve vibration；(2) two sides of valve gap are provided with tooth, make gas be divided into the most tiny air-flow when bloating, and reduce the diameter of bubble, increase gas liquid interfacial area, and mass-transfer efficiency increases；(3) valve lower limb is made up of elastic metallic material and valve lower limb tilts laterally so that float valve when being blown afloat by air-flow by buffering and the adjustment of feather valve lower limb so that it is be difficult to vibration；(4) float valve outer surface is provided with corrosion-resistant finishes, extends the service life of float valve.
