Description
Technical field
The present invention relates to a kind of float valve, belong to the technical field of chemical of gas-liquid mass transfer separation in chemical industry.
Background technology
Plate column is the classification contact mass transfer equipment that a class is used for gas-liquid or liquid liquid system, by cylindrical-shaped tower and by certain
Some column plates composition of the spacing horizontal device in tower.It is widely used in rectifying and absorption, is alternatively arranged as reactor for gas-liquid
Phase reaction process.Liquid flows successively through each layer column plate under gravity, from top to bottom during operation, to bottom of towe discharge;Gas exists
Under pressure differential is promoted, each layer column plate is sequentially passed through from bottom to top, to tower top discharge.The liquid of certain depth is remain on every block of column plate
Layer, 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 valve plate
On gas phase dispersion component；Can be floated on column plate, its open degree is changed with the change of gas flow.
F1 types（Also referred to as V1 types）Valve plate is the most frequently used column plate, but production practices show that F1 types float valve is being used
During there is problems with：（1）Because liquid level is different everywhere on column plate, when causing float valve to be blown afloat, each float valve is blown open
Time and the degree that is blown open it is inconsistent；（2）Air-flow is blown into liquid layer from valve opening surrounding, does not have guidance quality, and liquid foam entrainment increases
Plus, plate efficiency reduction；（3）The air pocket bloated from valve opening can not effectively be smashed refinement, make liquid phase contact mass transfer
Area is small, influences the raising of mass-transfer efficiency；（4）Float valve wear phenomenon is serious, and is easy to come off.
The content of the invention
Present invention solves the technical problem that being：A kind of one kind that can increase mass-transfer efficiency is proposed in view of the shortcomings of the prior art
Float valve.
In order to solve the above technical problems, the technical scheme is that：A kind of rectangle float valve, including quadrangle bonnet
With two valve legs, at least provided with a tongue apertures on the bonnet, the bonnet top is provided with the baffle plate being obliquely installed at tongue apertures,
Two relative sides of the bonnet are provided with tooth, and the bonnet bottom is provided with being formed around strip bulge, the projection
Multiple holes, the valve leg is arranged on bonnet bottom near another two side edge, and the valve leg is vertically arranged with bonnet, the valve
The lower end of leg is provided with valve pin, and the float valve outer surface is provided with corrosion-resistant finishes.
Above-mentioned technical proposal is improved to：The bonnet is rectangle, and the ratio of its side long and short side is 2：1, it is described
Tooth is arranged on two long edge positions of bonnet.
Above-mentioned technical proposal is improved to：The tongue apertures has two.
Above-mentioned technical proposal is improved to：The baffle plate and bonnet angle are 20 ° to 30 °.
Above-mentioned technical proposal is improved to：The teeth directional bonnet bottom bending.
Above-mentioned technical proposal is improved to：The corrosion-resistant finishes is the coating containing carbamide paint or polyurethane.
Beneficial effects of the present invention are：(1) bonnet is provided with tongue apertures, and when gas velocity is relatively low, bonnet is closed, and gas can
Sprayed by tongue apertures, bubbling is steady, float valve vibration can be reduced；(2) two sides of bonnet are provided with tooth, when bloating gas
Many tiny air-flows are divided into, the diameter of bubble is reduced, increase gas liquid interfacial area, mass-transfer efficiency increases；(3) valve
Being formed around strip bulge, the projection is provided with multiple holes in base portion, when air-flow hole is first passed through before bonnet is bloated
Segmentation, reduce the diameter of bubble, increase gas liquid interfacial area, mass-transfer efficiency increases；(4) float valve outer surface is provided with corrosion resistant
Erosion resisting coating, extends the service life of float valve.

Tooth 13, the bottom of the bonnet 1 is being formed around strip bulge 14, and described raised 14 are provided with multiple holes 15, and the valve leg 2 sets
Put in the bottom of bonnet 1 at two short sides, the valve leg 2 is vertically arranged with bonnet 1, and the lower end of valve leg 2 is provided with valve pin 21, float
Valve surface scribbles the corrosion-resistant finishes containing carbamide paint.
Embodiment two
The rectangle float valve of the present embodiment, remaining technical characteristic is identical with embodiment one, and difference is：The tongue apertures
Three are provided with, baffle plate 12 and the angle of bonnet 1 are 30 °.
Embodiment three
