Description

Connection device of acrolein ballast water treatment device
Technical Field
The present invention relates to a connecting device for connecting an acrolein ballast water treatment device for producing an aqueous acrolein solution to a main ballast water flow pipe leading from around a ship to a ship ballast water tank, the connecting device comprising a drawing device for drawing a part of a ballast water flow from the main ballast water pipe and leading the part of the ballast water flow into the device for producing the aqueous acrolein solution; and a reflux means for refluxing a portion of the ballast water stream containing the aqueous acrolein solution to the main ballast water conduit.
Background
DE 102009023314 a1 discloses an apparatus for treating ballast water with acrolein, which is connected to a main ballast water line of a ballast water treatment plant, comprising a reactor unit for producing an aqueous acrolein solution by adding an acrolein derivative and water; a shunt tube connected to the main ballast water conduit for shunting a portion of the ballast water flow; a mixing apparatus connected to the bypass conduit and the acrolein solution supply conduit of the reactor apparatus and configured to dilute the aqueous acrolein solution from the reactor apparatus; and a return line for supplying the aqueous acrolein solution in the mixing device to the main ballast water line. The return pipe is provided with an annular nozzle designed for insertion into the main ballast water conduit, which annular nozzle comprises a nozzle ring on the inner circumference of which a plurality of nozzles are distributed. Downstream of the annular nozzle is a mixing orifice plate type flow disruption device.
According to DE 102009023314 a1, installation of a supply device for an acrolein treatment plant of ballast water requires interruption of the main ballast water conduit twice, once by installation of a T-piece with a flange face for withdrawing part of the ballast water flow and once by installation of an annular nozzle with a flange face. In practical use of the connection device, it has been shown that the work of twice interrupting the assembly and welding of the main ballast water line on the ship is very heavy.
In practical use of the device, it has been shown that the hydraulic losses of the fluid interference device with the mixing orifice are excessive. Furthermore, the opening of the annular nozzle may be clogged due to contamination.
Disclosure of Invention
It is an object of the present invention to provide a connection device for connecting equipment for producing an aqueous acrolein solution to a main line of a main ballast water stream introduced into a ballast water tank of a ship from around the ship, by which it is possible to facilitate equipping of the ship with a ballast water treatment device and also to achieve better mixing of the acrolein solution in the main ballast water stream.
This object is achieved by the features of claim 1, the dependent claims constituting further developments of the invention.
The connection device according to the invention for connecting a device for producing an aqueous acrolein solution to a main pipe of a main ballast water stream is characterized in that the extraction device and the reflux device are combined in one structural unit and each have a means for mixing the acrolein solution with the main ballast water stream.
The installation of the connection device according to the invention on the ballast water pipe is very simple, since only one cut at one location of the ballast water pipe is required. Furthermore, the partial ballast water flow mixes very well with the main ballast water flow BW with little hydraulic loss.
The uniform, turbulent mixing of the ballast water split with the main ballast water flow is promoted by the two parts of the apparatus, the withdrawal means and the return means, and their respective mixing means.
The extraction device of the coupling device according to the invention advantageously comprises a pipe section, the inner diameter of which is adapted to the inner circumference of the main ballast water conduit, and a conduit, radially inserted into the pipe section, which is designed as a suction pipe for part of the ballast water flow.
The advantage of this extraction device is that, on the one hand, a sufficient partial ballast water flow can be extracted from the main ballast water flow, and, on the other hand, the piping creates an asymmetric turbulence which facilitates the mixing of the partial ballast water flow with the main ballast water flow in the subsequent flow.
The extraction device of the connection device according to the invention comprises, in an advantageous manner, at its ends a first loose flange for connection to the main ballast water conduit and a second loose flange for connection to the return device, thereby making possible, in an advantageous manner, a modular design of the connection device.
The return device of the coupling device according to the invention comprises, in an advantageous manner, an annular nozzle comprising an inner pipe section provided with a plurality of strip-shaped, open-mouth spouts on its pipe circumference, and an outer pipe section, whereby an annular space is formed. In an advantageous manner, the strip-shaped, open-mouth spout is of an anti-fouling design, thereby reducing the risk of the spout becoming clogged.
According to an advantageous embodiment, the reflux unit comprises an injection tube which opens tangentially into the annular space formed by the inner and outer tube sections of the annular nozzle and through which the aqueous acrolein solution produced by the ballast water treatment plant is fed into the annular nozzle so that there is an adequate supply of liquid all around the orifice of the annular nozzle.
According to an advantageous embodiment, the sum of the strip-shaped opening areas of the spouts corresponds to the cross-sectional area of the injection tube, so that the possibility of occurrence of liquid back-flow is minimized.
In an advantageous manner, the nozzle strip-shaped openings have rounded corners and are staggered in a zigzag pattern over the circumference of the inner pipe section, so that a uniform discharge of liquid from the annular nozzle is achieved.
The modular design of the connection device is further improved if a flange ring for connection to a loose flange on the extraction device and a flange ring for connection to a loose flange on the downstream outlet device are provided between the outer pipe section and the inner pipe section.
In order to increase the tightness of the connection device, a flat sealing ring is advantageously arranged between the welding flanges of the pipe sections of the extraction device and a flat sealing ring is arranged between the welding flange of the outlet device and the second flange ring.
A further advantageous embodiment of the coupling according to the invention is characterized in that the pipe section downstream of the return device comprises a bellows which, on the one hand, makes possible a length compensation between the pipe section cut out from the main ballast water line and the length of the coupling and, on the other hand, due to its corrugation, an additional mixing effect.
The modular design of the connection device is further improved if at the end of the return device a flange for connection with an adjacent flange ring of the return device and a loose flange for connection with a designated flange of the main ballast water conduit are provided, respectively.
The connecting device according to the invention, by combining the withdrawal means, the return means and the outlet means into one structural unit, the mixing effect is substantially improved compared to the known device according to DE 102009023314 a 1. Since the extraction device, in addition to the annular nozzle, promotes mixing of the main ballast water stream with the acrolein solution through the suction pipe extending to the main ballast water conduit, the outlet device also promotes mixing of the main ballast water stream with the acrolein solution through the corrugation of the bellows, whereas in DE 102009023314 a1 only the annular nozzle and the mixing orifice facilitate mixing of the main ballast water stream with the acrolein solution.
Drawings
Further advantages, features and applications of the above invention may be derived from the following description in connection with the illustrated examples.
In the description, in the claims and in the drawings, the terms and specific reference designators in the following list of numerals are used. The specific diagram is as follows:
fig. 1 shows a coupling device according to an embodiment of the present invention, which is compact and can be directly installed on a main ballast water pipe.
Fig. 2 shows an exploded view of the connection device according to fig. 1.
Fig. 3 shows a cross-sectional view of the connection device according to fig. 1.
Detailed Description
As shown in the figures, the connecting means according to the invention comprise three components, namely a withdrawal means 4 for withdrawing a partial ballast water flow from the main ballast water flow BW, a return means 6 in the form of an annular nozzle 8 for returning the partial ballast water flow to the main ballast water flow BW, and an outlet means 10. Thus, as shown in fig. 3, the extraction device 4 is arranged upstream of the annular nozzle 8, while the outlet device 10 is arranged downstream of the annular nozzle 8.
The inner diameter of the annular nozzle 8 is adapted to the inner circumference of the main ballast water conduit through which the main ballast water flow BW flows. As can be seen in fig. 3, the annular nozzle 8 has a nozzle ring 14 which comprises an inner pipe section 16 provided with a plurality of strip-shaped open-ended nozzles 18 on its pipe circumference, and an outer pipe section 20.
Two flange rings 22 and 24 are welded in a fluid-tight manner between the inner pipe section 16 and the outer pipe section 20. Threaded studs 26 and 28 are inserted into the flange rings 22 and 24, these studs being threaded and can be assembled with other parts of the supply device 2 according to the invention by means of nuts 30 and 32.
Fig. 2 shows an exploded view of the coupling device 2, wherein the annular nozzle 8 comprises an injection tube 34 tangentially connected to the outer tube section 16. As can be seen from fig. 2 and 3, the nozzles 18 of the annular nozzle 8 are strip-shaped openings with rounded corners and are staggered in a zigzag pattern on the circumference of the inner pipe section 16. For example, the opening of the spout 18 has a length of 80 mm and a strip-shaped opening width of 6 mm. The sum of the strip-shaped opening areas of the spout 18 corresponds to the cross-sectional area of the injection tube 34. This type of design and arrangement of the nozzle 18 is contamination resistant and provides for a very good mixing of the partial ballast water stream with the main ballast water stream BW.
At typical flow velocities in the main ballast water line of about 2 m/s, the hydraulic losses of the connection according to the invention are only 15% to 20% of the hydraulic losses of the annular nozzle and mixing orifice combination according to DE 102009023314.
The extraction device 4 comprises a pipe section 36, the inner diameter of which is adapted to the inner circumference of the main ballast water line through which the main ballast water flow BW flows, and a suction pipe 38, which is inserted radially into the pipe section 36 and on which a connecting elbow 40 is provided as a suction pipe for the ballast water flow to the ballast water installation, for example according to DE 102009023314 a 1.
A portion of the ballast water flow withdrawn from the main ballast water flow BW enters the suction line 38 through a 90 degree elbow 40 with an orifice 42 in a direction opposite to the direction of flow of the main ballast water flow BW. As shown in fig. 2 and 3, the orifice 42 is concentric with the axis of the tube section 36. The ratio of the inside diameter of the orifice 42 to the inside diameter of the tube section 36 is about 0.25 to 0.33.
The pipe section 36 has two welding flanges 44 and 46 and two corresponding loose flanges 48 and 50. As shown in fig. 3, the extraction device 4 is connected to the annular nozzle 8 by means of a loose flange 50 by means of threaded studs 26 and nuts 30. In order to ensure a fluid-tight connection, a flat sealing ring 52 is provided between the welding flange 46 and the flange ring 22.
The portion of the suction tube 38 extending into the tube section 36 and the elbow 40 welded 90 degrees thereto, which is the same diameter as the suction tube 38, create an asymmetric turbulence in the main ballast water flow BW therethrough. So that additional mixing of the partial ballast water flow with the main ballast water flow BW is achieved in the lower annular nozzle 8.
The outlet device 10 comprises a bellows 54 having an inner diameter adapted to the inner circumference of the main ballast water conduit through which the main ballast water flow BW flows. The bellows 54 has two welded flanges 56 and 58 and two corresponding loose flanges 60 and 62.
As shown in fig. 3, the outlet device 10 is connected to the flange ring 24 of the annular nozzle 8 by loosening the flange 60, by means of threaded studs 28 and nuts 32. In order to ensure a fluid-tight connection between the return device 6 and the outlet device 10, a flat sealing ring 64 is provided between the welding flange 56 of the outlet device 10 and the flange ring 24 of the annular nozzle 8.
The bellows 54 of the outlet device 10 has at least two, and typically three to five, tube corrugations 66 providing additional symmetrical turbulence to the flow of ballast water exiting the annular nozzle 8 on the inner periphery of the bellows 54. The bellows 54 also serves as a compensating means for compensating for a deviation between the length of the pipe section cut out from the main ballast water pipe and the length of the connecting means.
The connecting device is characterized by being assembled from an annular nozzle 8 and an extraction device 4 arranged upstream as a baffle, which device comprises, at the same time, a ballast water treatment apparatus according to DE 102009023314 a1, for example, a suction pipe 38 for extracting part of the ballast water flow by means of a pump (not shown) of the ballast water treatment apparatus, and an outlet device 10, which is designed as a symmetrical baffle and is connected downstream of the annular nozzle 8, making it possible to compensate for the length of the connecting device 2.
According to fig. 1, the compact supply device 2 can be easily installed on the main ballast water line, only by removing one pipe section at the appropriate location. The welding flange is welded to the newly created pipe end of the main ballast water pipe and the coupling device 2 according to the invention can then be fitted to the water pipe directly together with the two flat sealing rings, as an alternative to the removed pipe section. The slight difference in length is compensated by the length adjustment of the outlet device 10 by the bellows of the outlet device.
In the practice of the invention, a section of the main ballast water conduit from the ballast water pump to the ballast water tank is cut at a suitable location and a section of the conduit is removed. The welding flange is welded to the newly created free pipe end. The distance between the sealing surfaces of the two welding flanges installed corresponds approximately to the distance between the sealing surfaces at the two ends of the connecting device 2 consisting of the extraction device 4, the return device 6 and the outlet device 10. The slight difference in length is compensated for by the outlet device 10.
