The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
As shown in Figure 1, the ventilative mast of compound type of the discharge of the hazardous gas for spitkit described in the utility model, it comprises one for the main leg 100 that is connected with exhaust emission device (marine main engine, LNG storage tank and filling gas station equipment) and is located at the some signal cross bars 110 on this main leg 100, wherein, main leg 100 is a signal mast, is vertically fixed on compass deck 50; Main leg 100 adopts stainless steel, its inside is also provided with the ventilative pipeline being connected with above-mentioned marine main engine, LNG storage tank and filling gas station equipment, that is to say, at main leg 100, as in signal mast, the hazardous gas that the device of the exhaust emissions such as this marine main engine, LNG storage tank and gas station produces is discharged by this ventilative pipeline.
Bottom and compass deck 50 junctions at main leg 100 are provided with some pillar stiffeners 120 for oblique support main leg 100, and these pillar stiffeners 120 are from supported on both sides main leg 100, to increase the structural strength of whole mast.
Some signal cross bars 110 are horizontally installed on this main leg 100 and (are in the present embodiment 4), symmetrically on these signal cross bars 110 are provided with some signal lamps 130.
In the present embodiment, blind disconnected between main leg 100 and these cross bars 110, to guarantee the air-tightness of the ventilative pipeline in main leg 100; When concrete installation, the weld between main leg 100 and cross bar 110 needs Radiographic test RT and makes pressure test.
As shown in Figure 2, the top on main leg 100 tops is provided with a Ventilated cap 300 for exhaust, and the hazardous gas of the ventilative pipeline in main leg 100 is discharged from this Ventilated cap 300; Wherein, this Ventilated cap 300 is the tube structure of a hollow, and the upper and lower both ends open 301,302 of this tube structure is vertically fixed on the top of main leg 100, the ventilative pipeline connection of its lower ending opening and main leg 100 vertically; In the present embodiment, the pyramidal structure that Ventilated cap 300 is big up and small down, the upper and lower opening diameter of cylindrical shell is less than cylindrical shell middle part diameter of section.
In Ventilated cap 300, be provided with captation 310, between Ventilated cap 300 and captation 310, be provided with exhaust passage 303; Wherein, captation 310 is arranged on directly over the ventilative pipeline of Ventilated cap 300 inside, for stopping that rainwater enters ventilative pipeline, and rainwater is discharged; This captation 310 comprises a water-collecting tray 312 and a drain hose 311, wherein, water-collecting tray 312 is for to be arranged on Ventilated cap 300 inside center places for collecting the inverted bucket-shaped disk body of rainwater, and the diameter of this disk body is not less than the diameter of section of Ventilated cap 300 upper end open 301, that is to say, rainwater will all fall in water-collecting tray 312.
Because the diameter of section at Ventilated cap 300 middle parts is greater than water-collecting tray 312, gap between the inwall of Ventilated cap 300 and water-collecting tray 312 outsides has formed exhaust passage 303, the total waste gas of ventilative pipeline of main leg 100 rises to water-collecting tray 312 places, along the exhaust passage 303 of water-collecting tray 312 outsides, discharges.
As shown in Figure 3, the bottom 200 of main leg 100 is fixedly connected with compass deck 50, the diameter of this bottom 200 is greater than the top of main leg 100, to above-mentioned ventilative pipeline and relief vent road are set as main frame permeability cell 210, LNG storage tank permeability cell 220 and gas station permeability cell 230, these relief vents coordinate the ventilative pipeline in main leg 100 to carry out exhaust emission.
The spitkit that is ventilating duct for some supply air lines, is also provided with ventilating duct air suctiton ventilator exhaust outlet 240 in this bottom 200; At this ventilating duct air suctiton ventilator exhaust outlet 240, airtight boiler check valve is set, to prevent that the gas discharging from can not pour in down a chimney; In addition, between ventilating duct air suctiton ventilator exhaust outlet 240 and compass deck 50, shrouding 250 is set, to avoid forming ventilate " dead angle ".
The utility model arranges ventilative pipeline the main leg 100 as signal mast is interior, and arrange with pillar stiffener 120 combinations, by pillar stiffener 120, support main leg 100 to guarantee the intensity of whole mast structure, make the utility model in as signal mast, there is the function of blow down gas; Greatly simplify the layout of whole mast, effectively reduced the laid down cost of boats and ships.
More than show and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
