Description
Technical Field
The invention relates to the field of petrochemical industry, in particular to a filling bay type inner floating roof.
Background
The inner floating roof refers to a floating roof which can always float on the liquid level of the liquid petrochemical product and float up and down along with the liquid petrochemical product. In the liquid petrochemical storage tank, the internal floating disc can scientifically and reasonably prevent the volatilization loss of the medium in the storage tank, and has the effects of saving energy, protecting the environment and improving the safety. The inner floating roof mainly comprises the following forms: a float-type inner floating roof, a full liquid-receiving honeycomb-type inner floating roof, a steel inner floating roof and a glass fiber reinforced plastic inner floating roof. At present, the domestic inner floating roof is mainly a floating cylinder type, and the rest accounts for a small amount. With the issuance of national standards such as GB31570-2015 discharge Standard for pollutants for oil refining industry and GB31571-2015 discharge Standard for pollutants for petrochemical industry, the requirement for treatment of VOCs in storage tanks is higher and higher. In particular, the issuance of GB50160-2018 'fireproof design Standard of petrochemical enterprises' obviously increases the demand of the steel inner floating roof. The technology of the carbon steel inner floating roof which is eliminated and has little market share has to be mentioned and used again. The domestic all-liquid-receiving honeycomb type internal floating roof is developed after years and has a large scale, but with the prolonging of the service time, the problems of structural design defects, honeycomb plate liquid inlet and the like also occur in sequence on part of the honeycomb type internal floating roof, and finally, the inclined and sinking plate is caused.
An oil gas volatilization space exists below the floating cylinder type inner floating roof skin cover plate, and the oil gas is dissipated to the upper part of the floating disc through a floating disc gap and an accessory facility and finally discharged to the atmosphere. The current VOCs treatment requirement and emission reduction requirement cannot be met. Because the structural operation process is influenced by fluctuation of the liquid level of the received and sent oil product, blowing replacement impact, stress blocking of a floating disc of the storage tank and the like, the oil product is very easy to collapse and sink, and the structural strength cannot meet the use requirement
The carbon steel inner floating roof takes a steel plate as a main raw material, the steel plate is heavy and easy to chuck after being manufactured, and after the floating cabin is corroded and leaked, the buoyancy of the floating cabin fails, so that accidents of deflection and chuck can occur, further serious explosion accidents can be caused, the installation and maintenance need to be performed with fire, and the safety risk is increased greatly; the operation of opening the gantry on the tank wall or opening the tank top is needed to be damaged, so that the structural strength of the storage tank is damaged; long construction period
The upper and lower plates of the full liquid-receiving honeycomb type inner floating roof honeycomb plate are glued, when the floating plate runs under resistance, the structure and the honeycomb plate are damaged, oil is splashed above the floating plate and then enters the honeycomb plate to cause buoyancy failure, and then the floating plate sinks to finally cause the sinking of the floating plate. Part connects liquid honeycomb formula inner floating roof producer entirely, has some defects in the aspect of the frame roof beam structural design for floating plate overall structure is not strong, has the problem in the design of girder in addition, does not have the both ends of shutoff roof beam, makes originally the girder of buoyancy element lose buoyancy, has become the oil storage space on the contrary.
The glass fiber reinforced plastic inner floating roof is a low-melting-point material, and does not meet GB50160-2018 fireproof standards for petrochemical industry enterprises, so that the glass fiber reinforced plastic inner floating roof does not meet popularization conditions.
