Description
Technical field
A kind of internal floating roof tank preventing volatilization, belongs to internal floating roof tank technical field.
Background technique
Current volatile liquid chemical products mainly use internal floating roof tank to store, and it is close that ligulate is installed between floating plate and tank body
Envelope, is that monolith forms, and relies primarily on elastic tongue piece and sealing function is played in tank body sliding contact, since tank body has ellipse
The problems such as degree, verticality are local camber moves up and down during receipt and payment material with floating plate, has under stress effect a certain amount of
Flexible deformation, minim gap can be generated, material Volatile Gas will enter the gas-phase space on floating plate.When storage tank rewinding, with
Liquid level rise, the mixed gas of the gas compartment compressed, and pressure constantly increases, when the pressure of mixed gas in pipe rises to
When the popping pressure of breather valve, just discharged by breather valve to atmosphere；After sunrise, with atmospheric temperature raising and solar radiation
Intensity increases, and the mixed gas expansion of the gas compartment, to make the pressure increase of mixed gas, the mixed gas of the gas compartment is swollen
It is swollen, to make the pressure increase of mixed gas, when pressure inside the tank reaches the release pressure of breather valve, will by breather valve to
Atmosphere discharge.As the generation of being on the rise for atmosphere pollution in recent years, the deterioration of air quality, especially haze is more and more strict
Evil, wherein volatile organic matter VOCs is the main source that haze is formed, and not only pollutes environment, also brings economic loss.
Summary of the invention

Compared with prior art, beneficial effect possessed by the utility model is:
1, it originally prevents from forming cushion chamber between the spring cylinder and inner tank wall of the internal floating roof tank of volatilization, when floating plate is gone up and down,
Spring cylinder can be entered in cushion chamber with floating plate synchronization telescope by the escaping gas overflowed between floating plate and inner tank wall,
Receipt and payment material whole process is closed, without outlet, completely eliminates tank discharge pollution problem, not only reduces energy consumption, and makes to store up
Tank pollutant emission improvement has reached new standard requirement, avoids the physical and mental health of damage worker, and originally prevents the inner floating roof of volatilization
Storage tank small investment, low energy consumption, operate without personnel and without waste discharge etc., with good economic efficiency and environmental benefit is answered
It is very wide with prospect, it is suitable for large-scale promotion.
2, sealing ring facilitates the sealed connection of spring cylinder upper end and tank body, and sealing ring is bent by angle steel, and intensity is high,
And the conveniently sealed connection with inner tank wall and elastic ring.
3, spring cylinder is corrugated tube shape, to make spring cylinder, elasticity is good, and then can preferably stretch with the lifting of floating plate
Contracting, will not cause obstacle to the lifting of floating plate, additionally it is possible to avoid causing spring cylinder to damage since buffering cavity pressure variation is excessive
The problem of.
4, the material of spring cylinder is hydrogenated nitrile-butadiene rubber, has good elasticity, and can be avoided to the material in storage tank
It pollutes.
5, ligulate sealing can be sealed between floating plate and inner tank wall, and material is avoided to overflow, additionally it is possible to be guaranteed floating
Disk is with the intracorporal liquid level synchronization lifting of tank.
6, floating plate is stainless steel plate, and intensity is high and is polluted after can be avoided corrosion to the material in storage tank, Er Qiefang
Just with the sealed connection of spring cylinder, pontoon can adjust the balance between the gravity of floating plate and buoyancy, guarantee that floating plate floats always
On material liquid surface.
