Benefits of technology
The invention is a feeder device for treating aqueous acrolein solution for use in shipping. The device is simple in construction and can handle large quantities of throughput with justifiable effort. It uses a ring nozzle with multiple openings to feed the acrolein solution to the main ballast water stream in a unitary manner, achieving good mixing with the ballast stream. The feeding unit also includes a flow interfering device to further improve the mixing process. The feeder device can be easily replaced in case of damage or wear. The non-circular shape of the mixing face plate improves the mixing function. The technical effects of the invention include improved effectiveness and convenience in treating ballast water on ships.
Problems solved by technology
Aqueous solutions of acrolein are not poisonous and can be safely handled, however, such solutions can only be handled during a few days such that the use on ships is impossible because of logistic problems.
Although the problem with the handling, the transport and the storage of pure acrolein on ships is solved in this apparatus, there are problems of the dimensioning, in particular of the water jet pump and the reaction container, with increasing requirements of throughput.

Embodiment Construction
[0022]FIG. 1 schematically shows an apparatus for treating ballast water with acrolein in which feeder device of the invention is employed. It is to be noted that the inventive feeder device may also be used independently from the total apparatus shown in FIG. 1.
[0023]As can be seen from FIG. 1, the main ballast water stream (volume / unit of time) BW of the ballast water to be treated with acrolein, flows through the main ballast water line 2 to a feeder device, a ring nozzle 4 with a nozzle ring 5 at the inside of which at least one nozzle opening 6, preferably a plurality of nozzle openings 6 arranged under equal spaces, are provided.
[0024]Furthermore, the feeding unit comprises a flow interfering device located downstream from the ring nozzle 4 as viewed in the direction of the main ballast water stream. The flow interfering device may be a restriction, a flow guiding device or another obstacle whereby the main ballast water stream coming from the ring nozzle, is whirled up and mi...
