Abstract
The utility model relates to a light diesel oil cooling device for marine power, which comprises a diesel oil service tank, a fuel oil service tank, a regulating valve, a supply pump, a circulating pump, and a preheater. The diesel oil service tank and the fuel oil service tank are arranged above the regulating valve and supply pump, and fuel oil is delivered into a cooler for cooling through the circulating pump; a viscosity gauge is arranged between the cooler and a filter; and a method of delivering the filtered fuel oil into a host machine can effectively improve the viscosity of the fuel oil. In the utility model, a cooling agent is not used for directly cooling MGO (marine diesel oil), thus avoiding the danger that the cooling agent enters the marine light diesel oil by means of leakage, and having safer and more reliable use.
Description
Technical field; The utility model relates to a kind of cooling unit, particularly relates to a kind of ship power Diesel oil cooling unit.
Background technique: along with the idea of environmental protection and improving constantly of requirement; emission request to boats and ships sulphide is more and more stricter; under the requirement of the 2005/33/EC of European Union meeting; the emission request that enters all boats and ships sulphur content at European Union member countries harbour from 2010-01-01 later on needs below 0.1%m/m; in order to satisfy this requirement; the boats and ships marine gas oil (MGO) that when navigating by water this zone, must burn; but main frame for original burning heavy fuel oil; subsidiary engine and boiler; former design proposal can not meet the demands; need be at main frame; increase the viscosity that the Diesel oil cooler improves Diesel oil in the oil-fired system of subsidiary engine; satisfy environment requirement; because zones such as International Maritime and European Union are to the requirement of low sulphur emissions; need change Low Sulfur Fuel Oil in ship's navigation during to this zone; and to reach the purpose that sulphur content is lower than 0.1%m/m, must burning marine gas oil MGO.According to the standard of ISO8217:2005MGO (DMA), viscosity is minimum 1.5CST (Li Shi viscosity) (40 ℃), can cause oil pump to kill because oil viscosity is crossed to hang down, and all are according to MAN B﹠amp; The main frame of the requirement of W main frame: MAN does not recommend to use fuel-viscosity variation to be lower than the oil of 2CST, main and auxiliaries can not changed any design, Given this, need in oil-fired system, increase cooler and reduce the oil temperature, thereby improve oil viscosity 2CST to reach the minimum requirements of main and auxiliaries.The purpose of this utility model addresses this problem exactly.
Summary of the invention: the purpose of this utility model will provide a kind of device exactly, can satisfy the requirement of main frame, the purpose of this utility model is to realize like this, ship power Diesel oil cooling unit, formed by the daily cabin of diesel oil, the daily cabin of fuel oil, modulating valve, supply pump, recycle pump, preheater, it is characterized in that: the daily cabin of diesel oil, the daily cabin of fuel oil are arranged on the top of modulating valve and supply pump, fuel oil cools off in recycle pump is transported to cooler, be provided with viscosity gauge in the middle of cooler and filter, the fuel oil after the filtration is sent into main frame; Also be provided with preheater between described recycle pump and cooler, preheater is controlled by viscosity gauge; Above the daily cabin of fuel oil, also be provided with and remove air valve automatically and remove inflator.The utility model is simple in structure, and is easy for installation, can reduce the pollution to environment effectively.

1, main frame 2, filter 3, viscosity gauge 4, steam-gas inlet 5, vapor outlet port 6, preheater 7, recycle pump 8, supply pump 9, modulating valve 10, the daily cabin 11 of fuel oil, air valve 13 is removed in the daily cabin 12 of diesel oil automatically, removes inflator 14, freezing mixture 15, cooler
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing
In the drawings, the utility model ship power Diesel oil cooling unit, formed by the daily cabin of diesel oil, the daily cabin of fuel oil, modulating valve, supply pump, recycle pump, preheater, it is characterized in that: the daily cabin of diesel oil, the daily cabin of fuel oil are arranged on the top of modulating valve and supply pump, fuel oil cools off in recycle pump is transported to cooler, be provided with viscosity gauge in the middle of cooler and filter, the fuel oil after the filtration is sent into main frame; Also be provided with preheater between described recycle pump and cooler, preheater is controlled by viscosity gauge; Above the daily cabin of fuel oil, also be provided with and remove air valve automatically and remove inflator.During concrete enforcement, if cooler is crossed when low the fuel cools temperature, can cause fuel-viscosity variation too high, be arranged on the viscosity gauge in the middle of cooler and the filter this moment, can control preheater and open steam valve, starts heating equipment automatically and give fuel heating.To selecting for use of cooling medium: cooling medium is generally taked: seawater, low temperature fresh water (36 ℃), refrigeration agent (freon) etc.Seawater: because the possibility that the leakage of fuel oil enters seawater, thereby Marine Pollution, so seawater should be as the cooling medium of Diesel oil cooler; Fresh water: low temperature fresh water temperature need be cooled to Diesel oil MGO 20-22 ℃ at 36 ℃, and possibility can not reach requirement so only only cool off with low temperature fresh water hardly; Refrigeration agent (freon R404a): do not recommend directly to use refrigeration agent to cool off Diesel oil, reason has following: (1) is because refrigeration compressor moved at most 8-10 hour and the restriction of compressor minimum injection rate 25%, so can not control fuel oil temperature well; (2) in case vaporizer leaks, refrigeration agent enters fuel pipe with pressure and the generation high pressure that expands rapidly in fuel pipe breaks pipeline suddenly, expanding rapidly causes that air pocket damages oil pump; Given this, need to adopt condenser system, usually be CHILLEDSYSTEM: briefly: promptly earlier make it to become chilled water with condensation unit refrigerant cools low temperature fresh water, the control temperature normally moves main frame, subsidiary engine with chilled water cooling marine gas oil to reach the temperature and the viscosity that need at 5-18 ℃ again.Ship power is reasonable in design simple with the Diesel oil cooling unit, arrange reliable, adopt modular design, compact structure by R404A refrigeration agent elder generation cooling water, cools off MGO with cooled chilled water again, reach good refrigeration effect, because refrigeration agent of no use directly cools off MGO (marine diesel oil), avoided refrigeration agent to enter into the danger of marine gas oil by the mode of seepage, use safer, reliable; The whole control system adopts programming automation control, by elements such as motor-operated control valve, temperature transducer, thermal switches whole system is carried out comprehensive automation control; This system also has been equipped with the complete system monitoring device of a cover, and whole system is carried out overall monitor, has guaranteed the normal operation of system and feedback fault and warning in time, provides maximum guarantee to the safety of boats and ships and this device.
