Problems solved by technology

Its main disadvantages are: because it enters from the DN600 manhole, the skins are very narrow, there are many joints between the skins, the joints connected by bolts and adhesives are not reliable, and people on the floating roof Disturbances when walking or lifting the floating roof will cause leakage at the seams
This will lead to an increase in VOC emissions; there is a gas phase space between the skin and the liquid surface, which is a safety hazard and will also cause an increase in VOC emissions; the volatile gas in the gas phase space between the inner floating roof and the tank roof will condense. Accumulated on the upper surface of the skin to form an effusion that cannot be removed; when a fire breaks out, the skin will deform due to heat, the adhesive will fail when heated, the joints between the skins will crack, and oil and gas will overflow from the cracks. to intensify the fire

Abstract

The invention discloses an assembling method of a factory modularized prefabricated floating roof. The assembling method is characterized in that the floating roof is divided into a plurality of modules, each module is prefabricated in a factory and then is transported into a storage tank, and according to the structure of the floating roof, field assembling and welding and installing are carriedout on the plurality of modules and components to form the factory modularized prefabricated floating roof. According to the assembling method, the field working strength is greatly reduced, the fieldworking time is greatly shortened, the installation working efficiency of the floating roof is improved, the floating roof is installed by adopting a method that an opening is formed in a tank wall or a tank roof of the storage tank as an installation channel, and thus workers can perform assembling, welding and inspection operations conveniently.

Description

Technical field [0001] The invention relates to the field of floating roofs, in particular to a factory modular prefabricated floating roof and an on-site installation method thereof. Background technique [0002] At present, the outer floating roof of the storage tank is a single-pan or double-pan steel floating roof welded on site. All are prefabricated, welded and painted on site. Long construction period; poor construction conditions, easy to be affected by weather and season conditions, construction quality is difficult to guarantee; the space in the floating cabin is small, welding and painting operations in the narrow space are likely to cause major safety accidents; 2006 At about 19:20 on October 28, 2005, an explosion occurred during the painting of the floating roof of a 100,000 m3 crude oil storage tank under construction in Dushanzi, Xinjiang, resulting in 12 deaths and 12 injuries. [0003] At present, the main types of internal floating roofs in storage tanks are: (...
