JPS60149815A - Disposal ship of public pollutant - Google Patents

Abstract

PURPOSE:To dispose of public pollutant without following generation of Toxic gas and odor by making the pollutant burn underwater, by a method wherein a plurality of pieces of multiarc welding rods is provided in the inside of the titled ship and an underwater incienerator which is made free from entering water outside of the ship or sea water from the bottom of the ship is provided within the ship. CONSTITUTION:An underwater incinerator 2 is inundated with water or sea water from the outside of a ship 1 through the bottom of the incinerator 2 and when waste matters 31 are thrown away within the underwater incinerator 2 through a belt conveyor 3, it becomes that the waste matters 31 are either mixed with or floated on the water or the sea water in the inside of the underwater incinerator 2. When voltage is applied to a space between each of multiarc welding rods 21, 22 in relation to the waste matters 31 which are under such state, the multiarc is heated even underwater up to arc heat of thousands of degrees, the waste matters 31 can be welded cleanly and can be made to burn by resolving the water into oxygen and hydrogen.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pollution treatment ship using a multi-arc (multi-phase multi-electrode arc welding machine). Traditionally, pollutants have been treated by burning them on land or by dumping them directly at sea. However, today there are an increasing number of pollutants that are unsuitable for treatment on land or dumping at sea.

The present invention addresses this current situation by applying multi-arc (multi-phase multi-electrode arc welding machine) technology to burn pollutants underwater to treat them without producing toxic gases or odors. It is something to do. First, the structure of the multi-arc, which is the premise of the present invention, will be explained. This was already invented by the applicant and patented at the Imperial Office, but the principle is that, as shown in Figure 1, the center point of the three-phase star-connected power supply l should be installed in the base material. 3 is of a conductive wire, said midpoint is installed and also connected to the base material), by connecting the ends of the other three-phase power supply to the respective welding rods 21, 22, 23 (in addition) Although FIG. 1 shows a three-phase case as described above, it is not limited to three phases, and may even have multiple phases.)

With this configuration, even if the base material to be welded and melted is not a metal material, an arc can be generated between the welding rods 21, 22, and 23 as shown in Figures 2 (a) and (b). As a result, it is possible to weld and melt base metals, which are non-conductive substances, regardless of whether they are in air, liquid, or powder.

In other words, in the conventional arc welding method that uses a single-phase power source and a single welding rod, since the arc between the welding rod and the base metal is used, it is a natural assumption that the base metal is also conductive. On the other hand, one feature of multi-arc is that it can weld base materials even if the base material is not a conductive material (multi-arc is different in other respects as well. However, since it is not directly related to the present invention, we will omit this point.)

The configuration of the present invention will be explained below with reference to the drawings.

As shown in FIG. 3, the present invention is constructed by providing an underwater incinerator in which a multi-arc welding rod is housed inside the hull, and the bottom part is freely floodable with water or seawater outside the hull.

That is, water or seawater floods into the underwater incinerator from outside the ship through the bottom of the incinerator, and for example, when waste is dumped into the incinerator by the belt conveyor 3 as shown in Figure 3, the waste is The material will mix with or become suspended in the water or seawater in the underwater incinerator. If a voltage is applied between each welding section of the multi-arc to the waste in this situation, the multi-arc will generate arc heat of several thousand degrees even underwater, decomposing the water into oxygen and hydrogen and disposing of the waste. The above-mentioned principle allows for clean welding and combustion. It is convenient to dispose of the incinerated waste at any time by providing an opening/closing section at the bottom of the underwater incinerator. In addition, in order to dump waste into the underwater incinerator using the belt conveyor 3, a lid is provided on the top or side of the underwater incinerator 2, and the underwater incinerator 2 is sealed from the outside during combustion. When dumping into an underwater incinerator, it is best to open it.

Although the present invention configured as described above makes it possible to burn waste underwater, the effects of the present invention are not limited to this.

In other words, due to multi-arc combustion, high-pressure steam is generated in the underwater incinerator, which rotates a steam turbine and converts it into mechanical energy to power the ship, as shown in Figure 4. It becomes possible to use it for power.

Moreover, the hot water in the underwater incinerator is guided into a heat exchanger attached to the underwater incinerator, and thereby can be used as a heat source for heating, cooking, etc. inside the ship 1. Furthermore, a large amount of distilled water can be obtained by extracting a portion of the high-pressure steam generated in the underwater incinerator 2 and cooling it. Furthermore, various gases are generated with the combustion of waste, and depending on the waste, effective gases (for example, nitrogen gas in melamine resin, amine resin, etc.) may be removed from the underwater incinerator and placed in the container 7. It will also be possible to store it and use it separately for the chemical industry.

On the other hand, if toxic gas is generated as a result of incineration, it is best to move the gas through a long pipe to the depths of the sea or lake and dump it into seawater or lake water to dissipate the toxic gas.

As described above, with the present invention, waste that is unsuitable for either ocean dumping or land treatment can be burned underwater in a ship using a new technology called multi-arc, and can be treated without toxic gas or odor. The heat energy generated by steam turbines, steam power generation, distilled water collection, heating,
It can be used as a heat source for cooking, etc.
