Abstract
The utility model relates to oil refining petrochemical field, in particular to a kind of fixing top storage equipment with floating plate, comprise tank body, in described tank body, floating disc is set, form annular space between described floating disc and tank body, the packing element be fixedly connected with described floating disc is set in described annular space; Described floating disc and packing element together form the overplate on liquid storage face, along with liquid storage fluctuates.Because described floating disc is attached to more than liquid level, liquid and gas in isolation tank body, decrease the volatilization of liquid.Tank deck arranges nitrogen sealing, and after passing into nitrogen, liquid storage and air no touch, be easy to ensure liquid quality, be specially adapted to the liquid chemical of premium oil and easy oxidation stain.
Description
Technical field
The utility model relates to oil refining petrochemical field, particularly a kind of fixing top storage equipment with floating plate.
Background technology
In oil refining, in petrochemical industry, the tank body of storing liquid raw material or product is a lot of all larger, volume generally from a few hectostere to a few ten thousand stere, usually according to different choice floating roof tank or the fixed tank of physical property.
When selecting the fixed tank not adding nitrogen envelope, due to outside air temperature change, tank internal pressure is caused to fluctuate.When pressure raises, material steam enters air and so-called little breathing from breathing valve, causes loss of material and environmental pollution.In addition, during each input and output material of large-scale storage tank, by material steam most of on liquid level from breathing valve discharge and so-called large breathing, larger loss and environmental pollution can be caused.
Floating roof tank adds a floating top cover in tank inside, and communicate with air in the perforate of tank top.Floating top cover fluctuates along with liquid storage, decreases the evaporation loss of storage process.But because floating plate top communicates with air, the material that evaporation is revealed all enters in air, causes certain environmental pollution to air.
Utility model content
The utility model, for the defect of prior art and deficiency, provides a kind of fixing top storage equipment of band floating plate of safer, environmental protection.
The technical solution of the utility model is:
With a fixing top storage equipment for floating plate, comprise tank body, in described tank body, floating disc is set, between described floating disc and tank body, form annular space, the packing element be fixedly connected with described floating disc is set in described annular space; Described floating disc and packing element together form the overplate on liquid storage face, along with liquid storage fluctuates.Because described floating disc is attached to more than liquid level, liquid and gas in isolation tank body, decrease the volatilization of liquid.
For reducing the material contaminated environment leaked out further, breathing valve and nitrogen sealing being set at tank deck top, utilizing the mode of inflated with nitrogen, dilute the material leaking to tank top from floating plate.When charging in tank or temperature rising cause pressure increase, breathing valve is opened, and discharges nitrogen; When discharge in tank or temperature reduction cause pressure increase, nitrogen envelope valve is opened, in tank, supplement nitrogen.
Preferably, described packing element is the flexible foam plastic envelope block of periphery sealant tape sealing.
The beneficial effects of the utility model are:
1, owing to stock solution level there being floating disc cover, liquid storage and tank body upper gas completely cut off, and reduce Fire explosion dangerous;
2, arrange nitrogen sealing, after passing into nitrogen, liquid storage and air no touch, be easy to ensure liquid quality, be specially adapted to the liquid chemical of premium oil and easy oxidation stain;
3, when sealing effectiveness is identical, compared with floating roof tank, can reduce evaporation loss further, this is because fixing top is without the cavity be connected to external world, even if a small amount of gas gone out from floating plate gap leakage is also by nitrogen dilution, reduces the pollution of air to external world;
4, the packing element of floating disc be soft seal not having under oxygen, not easily aging, effectively can improve the sealing property of floating disc and reduce the possibility that seal aging causes seal failure.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model specific embodiment;
Accompanying drawing 2 is the structural representation of packing element described in the utility model;
Accompanying drawing 3 is utility model works schematic flow sheet.
Wherein, 1 is tank body; 2 is floating disc; 3 is packing element; 4 for breathing valve port; 5 is nitrogen sealing; 6 is sealant tape; 7 is flexible foam plastic envelope block; 8 is liquidometer mouth; 9 is manhole.
Detailed description of the invention
In order to understand structure of the present utility model, feature and other object further, the appended preferred embodiment of existing combination is described in detail as follows, and illustrated preferred embodiment is only for illustration of the technical solution of the utility model, and non-limiting the utility model.
Detailed description of the invention of the present utility model is as follows: as shown in Figure 1,
With a fixing top storage equipment for floating plate, comprise tank body 1, in described tank body 1, floating disc 2 is set, between described floating disc 2 and tank body 1, form annular space, the packing element 3 be fixedly connected with described floating disc 2 is set in described annular space; Described tank body 1 top is arranged breathes valve port 4 and nitrogen sealing 5.
Described floating disc 2 together form the overplate on liquid storage face with packing element 3, along with liquid storage fluctuates.Because described floating disc 2 is attached to more than liquid level, liquid and gas in isolation tank body, decrease the volatilization of liquid.
For reducing the material contaminated environment leaked out further, breathing valve and nitrogen sealing being set at tank deck top, utilizing the mode of inflated with nitrogen, dilute the material leaking to tank top from floating plate.When charging in tank or temperature rising cause pressure increase, breathing valve is opened, and discharges nitrogen; When discharge in tank or temperature reduction cause pressure increase, nitrogen envelope valve is opened, in tank, supplement nitrogen.
Described packing element 3 is the flexible foam plastic envelope block 7 that periphery sealant tape 6 seals, soft seal is formed with tank body 1, not having under oxygen, not easily aging, effectively can improve the sealing property of floating disc and reduce the possibility that seal aging causes seal failure.
Through on-the-spot actual verification, a 5000m
3gasoline container, adopt the fixed tank of non-nitrogen envelope, an annual loss is failed to keep an appointment 195t gasoline; Adopt internal floating roof tank, an annual loss is failed to keep an appointment 20t gasoline; Adopt the fixing top storage equipment of band floating plate of the present utility model, within 1 year, loss amount is less than 5t.
