Abstract
Provided is an improved floating production storage and offloading (FPSO) sodium hypochlorite pipe system connecting device. A main deck seawater return circuit (1) and a device pneumatic distributing pipeline (2) are connected with a stem sodium hypochlorite processing unit (3). A pypocholoride conveying pipeline (6) is led out from the stem sodium hypochlorite processing unit (3) and connected with an application device through a conveying pump (9), and then chemical feeding injecting is conducted on a seawater conventional pump conveying pipeline (4) which is directly led out from the main deck seawater return circuit (1). By the adoption of reasonable design and pipeline laying, devices are laid in a safe area, pipeline transforming construction quantity is reduced, the FPSO ship body safe anti-explosion management requirement is adapted, work needs of a ballast water system is met, occupied area and space are small, stable pipeline work pressure is maintained and guaranteed, and ballast pump conveying work is controlled to be operated economically and safely.
Description
Technical field
The utility model relates to accessory equipment on International Classification of Patents B63B marine equipment technology or the B63J ship, especially improved type FPSO sodium hypochlorite guard system connecting device.
Background technology
The liquor natrii hypochloritis is a strong oxidizer, is used for papermaking, weaving, light industry etc. as bleaching agent, oxidizer and water scavengine agent, has the effect of bleaching, sterilization, sterilization.In the modern ships technology, the liquor natrii hypochloritis that the electrolysis ballast water produces has corrosive property, and its diffuser arrangement technology receives publicity.
FPSO belongs to the bigger ocean range vessel of the ballast water yield, ad hoc management system is controlled treated ballast water and is finished discharging, on pipe line arrangement, based on historical experience, according to the hull requirement of explosion proof, these pipelines need be installed in superstructure safety zonees such as cabin and overtime work, to avoid hazardous locations such as pump room and cargo hold.
Existing ballast water managerial tools and pipeline are settled and roughly are divided into two classes,, will change ballast line that is, and the ballast water main line is caused main deck, settle Ballast Management equipment again on main deck; Perhaps, relevant device is placed in the pump room, through equipment operation contrast, more than two kinds of methods all have tangible deficiency, the former, not only need a large amount of big rebuilding constructions, and must take the place, relevant range, influence the hull design function, simultaneously, improved pipeline causes pipeline transportation work pressure to be difficult to stable control, even influences the ballast pump normal operation; The latter obviously enters the hazardous location, is unfavorable for the hull safety management, also still has huge potential safety hazard even each equipment of system is carried out explosion-proof processing, and simultaneously, the cost input that is used for later stage safety management and maintenance also rises simultaneously, and is economical lower.The scheme that is suitable for is opener.
201,120,486,926 1 kinds of oil carrier Ballast Management of Chinese patent application system mounting structure, the electrolysis cells of Ballast Management system is installed in the cabin, from cabin seawater main line water intaking electrolysis, the liquor natrii hypochloritis who produces is upward through main deck above pump room in dosing pipe, be passed down through the ballast water dress water main line that main deck is injected into pump room then, realize the dosing of active substance.Neutralisation unit is installed in cabin or superstructure, and its dosing pipe also is that level is walked pipe above pump room on main deck, is passed down through the ballast water drain header road that main deck is connected to pump room, realizes the interpolation of neutralization reagent.For ballast water, active substance and the neutralization reagent that prevents the dangerous area flows to the safety zone, non-return valve is installed on dosing pipe, guarantee solution in the pipeline be from after nonreturn flow forward.
The utility model content
The purpose of this utility model is to provide a kind of improved type FPSO sodium hypochlorite guard system connecting device, to adapt to FPSO hull safety anti-explosive management expectancy.
Realize that the measure of the utility model purpose is: the pneumatic distribution circuit of main deck sea return and equipment connects into ship stern sodium hypochlorite processing unit, the hypochlorite diffuser is drawn by transmission pump from ship stern sodium hypochlorite processing unit and is connected application apparatus, and the conventional pumping line of seawater that the main deck sea return is directly drawn carries out the dosing injection then.
Advantage of the present utility model is, by adopting appropriate design and line layout, facility location is in safety zone, reduce the pipeline modification construction volume, adapt to FPSO hull safety anti-explosive management expectancy, satisfy the ballast water systems need of work, occupied ground and space are few, keep and ensure that the pipeline operation pressure is stable, the operation of control ballast water pumping operation economic security.
