Assembled steel full liquid receiving inner floating disc

Abstract

The invention discloses an assembled steel fully liquid-contacted inner floating plate, including single plate, double plate, floating plate legs, guide pipe, oil measuring pipe, manhole, secondary seal, air hole, static electricity conducting facilities, etc. ;The single-plate is inside the floating plate, single-layer steel structure, and different specifications are designed according to the size of the storage tank; Isolation, divided into several buoyancy units, with diagonal braces and vertical ribs to ensure the structural strength and connection strength; the outriggers of the floating plate support the entire floating plate when the liquid level is low; the guide pipe is anti-rotation to increase stability; plate, to realize the sampling operation during the operation of the storage tank; the manhole is the passage of the upper and lower space of the floating plate; the secondary seal is a primary bladder seal and a secondary scraper seal, which reduces the contact area between the storage medium and the air and achieves efficient sealing; the vent valve Eliminate the negative pressure in the space of the floating plate; the static conduction facilities are installed on the upper surface of the floating plate to guide and eliminate the accumulated charges and eliminate potential safety hazards.

Description

technical field [0001] The invention relates to an assembled steel fully liquid-contacted inner floating plate, in particular to an inner floating plate for preventing volatile organic compounds from escaping in a large atmospheric pressure light oil storage tank. Background technique [0002] Oil storage tanks are key equipment in the production, processing, delivery, storage and transportation of oil products. Most refined oil and intermediate products are highly volatile. In order to suppress oil volatilization, internal floating disk technology has been widely used in my country. application. At present, most of the floating discs used in China are iron floating tank type inner floating discs and buoy type inner floating discs. The iron buoyant inner floating plate has the disadvantages of heavy weight, easy corrosion, and high maintenance cost, while the buoy type inner floating plate has oil and gas space, which poses a huge safety hazard. At the same time, the above ...
