Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the word "over" a first feature or feature in a second feature may include the word "over" or "over" the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature "under" a second feature may include a first feature that is directly under and obliquely under the second feature, or may simply mean that the first feature is at a lesser elevation than the second feature.
As shown in fig. 1, the boiler water drain apparatus for a ship according to an embodiment of the present invention includes an intake pipe 1, an intake valve 2, a drain pipe 3, at least one drain valve 4, and a vacuum break valve 5, the intake valve 2 selectively communicating the intake pipe 1 with a boiler 100, the drain valve 4 selectively communicating the drain pipe 3 with the outside of the ship, the drain pipe 3 being partially located above a waterline 200, and the vacuum break valve 5 being disposed above the waterline 200 and at the highest position of the drain pipe 3.
The boats and ships boiler water discharging equipment of this embodiment adopts compressed air as power, the switching through admission valve 2 and discharge valve 4 is impressed boiler water and is discharged overboard behind discharge pipe 3, compare in the scheme that sets up bleeding cabin and discharge pump, the cost is lower, the construction degree of difficulty is little and facilitate the use, discharge pipe 3 part sets up and can avoid outboard sea water to get into boiler 100 under the condition that discharge valve 4 became invalid above waterline 200, vacuum break valve 5 can prevent that discharge pipe 3 is inside to produce negative pressure or vacuum, avoid discharge pipe 3 because of inside and outside pressure differential is too big to produce deformation or fracture.
Preferably, the portion of the drain pipe 3 above the water line 200 is in an inverted U shape, so that the boiler water is less resistant to the resistance and can pass through more rapidly.
Preferably, the discharge valves 4 are two in number and are arranged in series at the end of the discharge pipe 3. If only one discharge valve 4 is provided, since the discharge valve is directly contacted with the seawater, the discharge valve is easily damaged due to corrosion, and the two discharge valves 4 are provided, one discharge valve 4 is not directly contacted with the seawater, so that the reliability is improved.
Further, one discharge valve 4 is a stop check valve, and the other discharge valve 4 is a stop valve. By providing one of the discharge valves 4 as a stop check valve, the reverse flow of seawater into the interior of the discharge pipe 3 can be effectively prevented. Both discharge valves 4 are not provided as a check valve in consideration of the fact that the check valve may cause a certain resistance to the discharge of boiler water.
Preferably, the discharge valve 4 as a shut-off valve is a primary valve, and the discharge valve 4 as a shut-off check valve is a secondary valve. The primary valve, i.e., the valve through which boiler water is discharged first, and the secondary valve, which is located downstream of the primary valve, are distinguished according to the flow order of the medium. The discharge valve 4 as a stop check valve is used as a secondary valve, and after the introduction of compressed gas is stopped, external seawater cannot flow backwards into the primary valve and the discharge pipe 3, so that the primary valve and the discharge pipe 3 are protected.
The invention also provides a using method of the marine boiler water discharging device, which comprises the following steps:
s10, providing an air inlet pipe 1, an air inlet valve 2, an exhaust pipe 3 and two exhaust valves 4;
s20, opening an air inlet valve 2 and two discharge valves 4 after the boiler 100 is cooled;
s30, introducing compressed air into the air inlet pipe 1 to convey boiler water into the discharge pipe 3 and discharge the boiler water to the outside of the ship;
s40, closing the air inlet valve 2 and the two discharge valves 4 after the boiler water is discharged.
Preferably, the pressure of the compressed air is 2-5 atm, so as to ensure that the boiler water can be pressed to a sufficient height to be higher than the water line 200 and to pass through the highest position of the discharge pipe 3.
Specifically, when the boiler water discharge operation is started, the discharge valve 4, which is a primary valve, is opened, the intake valve 2 is opened to introduce compressed air, the boiler water is introduced into the discharge pipe 3, and the discharge valve 4, which is a secondary valve, is opened to discharge the boiler water overboard. The method can prevent the discharge valve 4 as a primary valve from being impacted by boiler water, so that the discharge valve has longer service life and higher reliability.
Further, after the boiler water is discharged, the discharge valve 4 serving as a secondary valve is closed, then the intake valve 2 is closed, and then the discharge valve 4 serving as a primary valve is closed, so that the discharge valve 4 serving as a primary valve is not directly impacted, and the service life and the reliability of the discharge valve are prolonged.
The embodiment of the invention also provides a ship, which comprises the ship boiler water discharging device of any one of the embodiments, and can discharge boiler water very conveniently.
