Description

Technical part

The utility model belongs to the area of the treatment plant for the ballast water of the ships, whereby the treatment systems for the filtering and UV-ultrasound in particular go to the ballast water of the ships.

Background of the technique

The threats that the sea has to face on Earth can be classified into the following categories: the invasion of marine organisms into other biological systems in the ocean; pollution from the mainland; the overfishing of marine resources and physical destruction in the habitat of marine life. From this, ships should be responsible for the fact that marine organisms have invaded the other biological systems from the sea because it is the ballast water from the ships that contain the marine life and also those that are absorbed at the hull of the body of the ships , The ballast water is the main route for the distribution of marine life between the different locations in the waters that are geographically isolated. More than 80% of the global merchandise trade is transported by ship, and there are approximately three to five billion tonnes of ballast water in the world every year, moving through the ships along the seashore. Every year there is also a large amount of ballast water that moves in the interior of different countries and between different regions. For the modern transport the ballast water is necessary. It can guarantee the safety of ships and high performance operation, ensuring the balance and stability of ships without goods. But it also brings threats to the economic environment, to the economy and also to human health. In 2004, "the International Pact on the Management and Control of Ships' Ballast Water and Sediment", proposed at the 45th session of the IMO-Maritime Environmental Protection Committee (MEPC) to pass the diplomatic meeting, became a compulsory one become an international pact. The main content of the pact is the control of ballast water, which contains the dangerous aquatic organisms and the dangerous pathogens, and the residual transfer. The pact calls for: ships to carry out the exchange of ballast water in the deep sea and in open water and as far as possible from the coast. It should be at least 200 nautical miles away from the mainland and at least over 200 meters deep. Therefore, ships need to install the safe, efficient, fast ballast water treatment system at a low cost.

In combating the pests infested by the ballast water from the ships, the larger organisms are removed by the physical filtration. But because of the small size of the tiny protozoa and protozoa you can not effectively remove them. Scientists and researchers have done a great deal of research to prevent pest infestation by the ballast water from the ships: e.g. B. There is a method of exchange of ballast water in the deep sea. This method is a feasible measure that effectively reduces the invasion of alien species. But there are also such problems, such. B. the high energy consumption, the long operation and operating time; There is also a method for heating the ballast water. But the cloisterium in the ballast water can be killed after the water temperature of 38 ° C after two hours. So there are the difficult to overwhelming problems, such. As the long treatment time, the high energy consumption, and the heat load formed will affect the safety of the ship.

Content of the utility model

Purpose of the utility model: The purpose of the utility model is to provide a ballast water treatment plant from the ships to solve the problems of low efficiency and high cost, as well as the regeneration of the microorganisms from the already processed sea water in the ballast tank prevent.

Technical solution: To the o. G. In order to solve technical problems, this utility model has offered the treatment method and equipment for filtration and UV ultrasound to the ballast water from the ships. This utility model includes solenoid valves, water pumps, pressure sensors, flow meters, filters, the integrated processing unit of UV ultrasound, control system, solenoid valves and piping. The water goes through the pipes in the filter and then through the UV system, the living creatures are killed. Finally, the water is relieved. The UV ultrasound device works very well during the sterilization. The ultrasound destroys the protective layer of the microorganisms, and the UV radiation will destroy DNA and RNA from the microorganisms. At the same time the ultrasound will also purify the UV lamp to a certain extent.

As an advantageous invention, the inner wall of the presented UV ultrasonic processing unit is highly polished.

As an advantageous invention, the frequency of the ultrasonic treatment device is 15 ~ 75 kHz.

As an advantageous invention, the presented filter uses an automatic microporous filter, the accuracy of which is between 10 ~ 100 μm.

The housings of the featured filter and the presented UV ultrasonic processing unit may be densified by the stainless steel or titanium alloy material inside.

In the ultraviolet ultrasonic processing unit, according to the number of indoor lamps and the processing requirements, the housing can be shaped in the shape of a cylinder or a cuboid, etc.

The water inlet from the UV ultrasonic processing unit can be installed above or below the unit.

For the presented UV generator you can use the amalgam lamps with low, medium and high voltage output.

For the presented UV lamp tube you can use natural or artificial quartz.

The Mercury located in the UV lamps is isolated from the outside world by the isolation devices. This insulation device is planned as a thin layer whose material is plastic or materials that can not make any chemical reactions with mercury.

The presented control system can be operated by just one button. This system is completely intelligent. All you have to do is press any key and then the system can be started automatically. It needs no subsequent operation. Even in the event of an emergency, the system itself can automatically eradicate this case. For example, the system can control the individual treatment of the UV device and the ultrasound device and the coordinating treatment of the UV ultrasound device.

Useful effect: The utility model will efficiently kill the microorganisms in the ballast water of the ships, resulting in low energy consumption and reliability is quite high. Operation and maintenance of the devices are very easy. The self-control unit can operate the devices via one-button operation or, depending on the actual situation, choose the mounting platforms flexibly.
