Device for storing and dissolving chemical for disinfecting ballast water

Abstract

The present invention relates to a device for storing and dissolving a chemical, the device being configured to prepare a chemical solution, in which a chemical for disinfection is dissolved, and to supply the same to ballast water piping. More particularly, the present invention relates to a device for storing and dissolving a chemical for disinfecting ballast water, wherein a cylindrical holding case is fixed / installed in the vertical direction on the upper portion of a chemical dissolution tank, in which a solvent (fresh water or seawater) is introduced and stored; a chemical storage barrel having the shape of a circular or polygonal barrel is inserted / installed in the vertical direction into the holding case; multiple vertical chemical storage chambers are formed in the inner space of the chemical storage barrel by a radial partition plate; a chemical injection opening is formed on the bottom surface of the holding case so as to correspond to one chemical storage chamber; the chemical storage barrel is rotated in an upright state such that each chemical storage chamber successively corresponds to the chemical injection opening, thereby enabling a rated amount of injection of the chemical through the chemical dissolution tank in a natural drop type; this guarantees safer management and use of a chemical of an oxidizer type, which has toxicity harmful to human bodies; in addition, each chemical storage chamber stores the exact amount of chemical required for disinfecting ballast water once, and the corresponding chemical can be injected into the chemical dissolution tank with no remnant; this prevents unnecessary waste of the chemical and the solvent and guarantees rapid and accurate preparation of the concentration of the chemical solution as needed without having to apply a complicated control system for adjusting the concentration of the chemical solution.

Description

technical field [0001] The invention relates to a chemical storage and dissolving device for ballast water sterilization treatment, a cylindrical control box fixedly installed in the vertical direction on the upper part of the chemical dissolution tank where the solvent (fresh water or sea water) flows into and stores; Inside the box, a cylindrical or polygonal cylindrical drug storage barrel is inserted and installed in the vertical direction; the inner space of the above drug storage barrel is formed by radial partitions to form a plurality of vertical drug storage rooms. On the other hand, due to the above-mentioned control The bottom surface of the box forms a medicine input port corresponding to one medicine storage chamber, so that the above medicine storage barrel is kept upright and rotated, and each medicine storage chamber corresponds to the medicine inlet in turn, so that the medicine passing through the medicine dissolution box can fall freely And invest quantitati...

Problems solved by technology

[0012] However, according to the above-mentioned method, since the input amount of chemicals and solvents required for one round of ballast water sterilization treatment has room to exceed the standard value, not only will it cause unnecessary waste of chemicals and solvents, but in order to be compatible with the chemical storage tank and In order to adjust the concentration by transporting the screw device together with the chemical dissolution tank, it is necessary to install an additional control system, which increases the installation cost. Not to mention the economic burden caused by this, there is also the troublesome problem of installing an additional control system in the small space in the ship.
