Description

Field of technology

BACKGROUND OF THE INVENTION The present invention relates to a device for applying corrective agents, in particular to compositions for limiting the growth of cyanobacteria on bodies of water, comprising a water nozzle attached to a vessel and arranged in a channel between its inlet and outlet.

The prior art

When contaminating water bodies with cyanobacteria, plankton, algae, oil, etc. there is a threat to aquatic animals and at the same time to the health of the users of water bodies, which is increasingly reflected in recreational areas.

Basically, two methods are used to eliminate the contamination of water bodies. One way is to powder water surfaces with correction agents from aircraft, the other way to powder correction agents from vessels.

Airborne dusting is disadvantageous due to the frequent dispersion of the correction agents beyond the water surfaces, which leads both to environmental hazards outside these areas and significantly increases the amount of correction agents required to effectively remove contaminants on the water surfaces and thus substantially increases the cost of the process.

Powdering of correction products from vessels is very time consuming, the whole process is unproductive and it is realistic to apply it only to smaller water bodies.

It is an object of the present invention to provide corrective jig application devices that allow for more effective and targeted correction jig application without adversely affecting the environment around water bodies from an ecological point of view.

SUMMARY OF THE INVENTION

The essence of the device for applying correction jigs according to the invention consists in that an on-board ozone generator is connected to the water nozzle, which is arranged in the channel containing the propulsion, through a connecting line.

The outlet part of the water nozzle is in the shape of a Venturi tube with an axis in the direction of movement of the vessel, with the junction of the connecting line into the water nozzle situated behind the propulsor

The advantage of this device for the application of the correction agent is the possibility of effectively utilizing ozone as a correction agent, especially for limiting the growth of cyanobacteria on water bodies, where ozone has very strong oxidizing properties, oxidizing very rapidly compounds present in water and being a very strong bactericidal and virucidal agent. Unlike other oxidizing agents such as chlorine, ozone treatment does not produce toxic products that would have to be removed subsequently.

Overview of the drawings

The attached figures show schematically a device for applying correction jigs, wherein Fig. 1 shows the device in partial section, Fig. 2 shows an axionometric view of a vessel with the device according to Fig. 1.

DETAILED DESCRIPTION OF THE INVENTION

A water nozzle 2 is formed on the vessel 1, forming part of the channel, in which the propulsion 3 is arranged to drive the vessel 1. The propulsion is driven by a motor 4. The inlet opening of the channel is arranged in the direction of the vessel I and its outlet opening away L The channel consists of a substantially upwardly facing inlet section and a substantially horizontal outlet section. The axis of the exit section is parallel to the longitudinal axis of the vessel L

On the vessel there is further provided an ozone generator 5, which is connected to the water nozzle 2 by a connecting line 6, eg a hose. The connecting line 6 opens into a water nozzle downstream of the propeller 3.

As the vessel travels on the water surface while operating the ozone generator 5, the water in the nozzle 2 mixes the water passing through the channel with the propulsor 3 and the ozone, which is thus relatively evenly distributed in the water flow coming out of the water nozzle 2. The use of ozone as a correction agent in the installation achieves a high degree of removal of impurities in the water reservoirs in a very short time and in only the desired area, without ecological threat to other sites.
