Description
Technical field
The utility model relates to chemical industry environmental protection field more particularly to a kind of single disc-type internal-floating cover of stock tank.
Background technique
With petrochemical industry unit in all parts of the country and each major oil companies and oil plant, port and pier, traffic, power plant
And army rear service department, for being widely used for oil mass, oil storage facility be also it is more and more, it is most common or oil storage tank to make
With, wherein storage tank floating plate is essential energy-saving environmental protection device in these oil storage tanks, and internal-floating cover of stock tank is that one kind passes through buoyancy
It is allowed to the energy-saving environmental protection device being covered on liquid level gone up and down with storage tank liquid surface lifting.To reduce medium volatilization in storage tank, drop
Low-loss is energy saving, protects environment, floating plate in this is added in storage tank.Storage tank by installation floating plate sealed storage medium,
It reduces medium temperature and reaches energy saving, protect the effect of environment.Currently, the structure and style of storage tank floating plate is also a variety of more
Sample is generally divided into steel formula iron buoyancy module floating plate, float-type floating plate, the board-like floating plate of honeycomb, floating box type floating plate, although this few class floating plate
Respective advantage is suffered from, but also exists simultaneously different degrees of hidden danger, steel formula iron buoyancy module floating plate is high, stupid due to cost
Weight, construction period are long, need scene to get angry welding, buoyancy unit is few, and the easy chuck of easy to leak causes to deform, maintenance is not easy to groove tank
And expense is high；The leakproofness of float-type floating plate is not strong, there is volatilization space, each self-dispersing of buoyancy unit, vulnerable to disengaging medium shadow
It rings and generates fluctuation, cover board is thin, be easy to cause deformed damaged, and service life is short, and also not can guarantee people can freely walk in floating roof
Construction；Although the board-like floating plate of honeycomb has breakthrough and improves in configuration aspects, leakproofness is enhanced, it is convenient to construct, and is easy group
Dress, but its structure is excessively complicated, inconvenience is brought for the installation of other floating plate auxiliary accessories, due to auxiliary facility
It is not perfect, so that the safety of floating plate itself is had a greatly reduced quality, and lack effective discharge to oil gas；Floating box type floating plate buoyancy tank knot
Structure is insecure, and buoyancy tank quality can not detect, easy to damage by medium fluctuation buoyancy tank, dismantles the buoyancy tank for having medium and causes safe thing
Therefore often there is declaration of an accident in recent years, therefore state security department has sent the documents at present gradually to ban such floating plate.And it is above-mentioned
Several floating plate sealings only inhibit the volatilization of liquid level, and not to reservoir walls, it is no group that remaining medium volatilization, which control effectively,
Knit discharge.
