Abstract

<P>PROBLEM TO BE SOLVED: To solve a problem wherein there is a seeping risk of seawater into smoke tubes because holes are easily opened in the smoke tubes in a boiler for boiling water by passing seawater through the outer peripheries of the smoke tubes. <P>SOLUTION: The smoke tubes 1 for boiling water made of steel, stainless steel, or the like, are arranged in a can 2 for boiling seawater flowing through a water boiling chamber 9 formed around the smoke tubes 1, and zinc 3 subjected to erosion and melting by the seawater is mounted into the can 2. Fire and smoke caused by a burner pass through inside the smoke tubes 1 formed of a hard steel material such as stainless steel, and seawater flows through the water boiling chamber 9 at the outer periphery. The seawater is heated, but at the same time, the zinc 3 of high solubility is eroded and melted by the stream of the seawater. At this time, since ion electrons of seawater flow first to the side of zinc 3 of low electric potential as electricity, the flow of the ion electrons in the seawater in the can 2 decreases, and electricity hardly flows to the smoke tubes 1 made of steel, stainless steel or the like, to obtain a state of hardly causing erosion and melting of the smoke tubes 1 to thereby prevent opening. <P>COPYRIGHT: (C)2008,JPO&amp;INPIT

Description

  Seawater hot water is used to remove and clean shells, seaweeds, etc. adhering to marine aquaculture equipment, but it is related to boilers that boil such seawater, and prevents erosion and perforation of smoke pipes. .

  There is known a technique in which a large number of smoke pipes are arranged inside a can that allows seawater to pass through, and the seawater is boiled through the combustion flame and smoke produced by a burner.

The invention described in claim 1 includes a hot water made of steel or stainless steel in a can body 2 having an inlet 11 for connecting a pump hose for feeding seawater and an outlet 12 for connecting a drain hose such as a nozzle. A boiling smoke tube 1 is arranged, a hot water chamber 9 is formed around the smoke tube 1, and seawater passing through the hot water chamber 9 from the inlet 11 to the outlet 12 is heated, and the peripheral wall of the can 2 An attachment port 4 is formed in a part, and inside the attachment lid 5 that closes the attachment port 4, a zinc lump that is subjected to erosion and dissolution by seawater, and an inner surface of the zinc three lump is placed on the inside of the can body 2 It is set as the boiler structure characterized by being attached to the hot water chamber 9 inside the attachment port 4 so that it can be attached or detached and can be exposed to the flowing hot water .
Inside the smoke pipe 1 made of a hard steel material such as stainless steel, a flame is burned by a burner. Seawater is fed into the outer water heater chamber 9 from the inlet 11 through the inlet 11, flows to the outlet 12, and is injected from the nozzle. Seawater flowing from the inlet 11 to the outlet 12 in the water heating chamber 9 is heated by a flame passing through the smoke pipe 1 or the like. At the same time, the inner surface of the highly soluble zinc 3 lump is caused by the flow of the seawater. It is eroded and dissolved. At this time, since the ion electrons of seawater first flow toward the zinc 3 having a low potential as electricity, the flow of ion electrons in the seawater in the can 2 is reduced, and a smoke tube made of steel or stainless steel is used. The flow of electricity to 1 becomes difficult to be performed, and the smoke tube 1 is prevented from being eroded and dissolved to prevent perforation.

In such a water heating chamber 9, seawater flows and is heated, and at the same time, the zinc 3 is eroded and dissolved by the flow of seawater. And when this zinc 3 lump is reduced by erosion and dissolution, the mounting lid 5 that closes a part of the mounting opening 4 of the can body 2 is removed, and the residual attached to the inside of the mounting lid 5 is removed. The zinc 3 is removed from the attachment port 4 to the outside of the can body 2 together with the attachment lid 5, and a new zinc 3 mass is replaced with the attachment lid 5. When the attachment lid 5 is attached to the attachment port 4, the three zinc parts are inserted into the hot water chamber 9 from the attachment port 4 and positioned on the inner peripheral surface portion of the can body 2. By simply opening and closing the attachment port 4 formed on the outer peripheral portion of the can body 2 with the attachment lid 5 having the zinc 3 attached to the inside thereof, this zinc 3 lump can be easily attached from the outside of the can body 2 to the inside of the hot water chamber 9. be able to.

In the first aspect of the present invention, the seawater flowing from the inlet 11 to the outlet 12 in the water heater 9 is heated by a flame passing through the inside of the smoke pipe 1 and the like. The inner surface of the high zinc 3 mass is eroded and dissolved. At this time, since the ion electrons of seawater first flow toward the zinc 3 having a low potential as electricity, the flow of ion electrons in the seawater in the can 2 is reduced, and a smoke tube made of steel or stainless steel is used. The flow of electricity to 1 becomes difficult to be performed, and the smoke tube 1 is prevented from being eroded and dissolved to prevent perforation.

In such a water heating chamber 9, seawater flows and is heated, and at the same time, the zinc 3 is eroded and dissolved by the flow of seawater. And when this zinc 3 lump is reduced by erosion and dissolution, the mounting lid 5 that closes a part of the mounting opening 4 of the can body 2 is removed, and the residual attached to the inside of the mounting lid 5 is removed. The zinc 3 is removed from the attachment port 4 to the outside of the can body 2 together with the attachment lid 5, and a new zinc 3 mass is replaced with the attachment lid 5. When the attachment lid 5 is attached to the attachment port 4, the three zinc parts are inserted into the hot water chamber 9 from the attachment port 4 and positioned on the inner peripheral surface portion of the can body 2. By opening and closing the attachment port 4 formed on the outer peripheral portion of the can body 2 with the attachment lid 5 having the zinc 3 attached on the inside, the zinc 3 lump is attached to the attachment port 4 inside the hot water chamber 9 from the outside of the can body 2. Can be easily installed in the position of the part.

  Based on the illustrated example, a combustion chamber 6 is formed at the lower end portion and an exhaust chamber 8 having a chimney 7 at the upper end portion is formed inside the vertical cylindrical can 1, and these upper and lower combustion chambers 6 are formed. Then, a hot water chamber 9 is formed in which smoke pipes 1 of an appropriate diameter communicating between the exhaust chambers 8 are arranged at appropriate intervals. The can body 2 and the smoke pipe 1 are made of stainless steel or steel. The lower end of the hot water chamber 9 communicates with a lower hot water chamber 10 formed around the combustion chamber 6. In the lower part of the hot water chamber 9 formed on the outer peripheral part of the combustion chamber 6 and the smoke pipe 1 and the like, an inlet 11 for allowing seawater to flow in, a drain port 19 and the like are formed. An outlet 12 through which hot water that is heated and rises is provided. A burner mouth tube 13 is provided in the combustion chamber 6 so that a burner 14 installed on the outside faces. The burner tube 13 has a mounting plate 15, and a burner 14 is attached by a set bolt 16. An attachment port 4 is formed on the outer periphery of the intermediate portion of the can body 2. The mounting lid 5 is overlapped with a seal 18 from the outside of the mounting port 4, and the mounting lid 5 is detachably mounted by tightening bolts 17. Inside the mounting lid 5, three pieces of zinc are attached by bolting or pasting. When this attachment lid 5 is attached to the attachment opening 4 part, the zinc 3 is positioned in the hot water chamber 9 in the can 2 so that the hot water chamber 9 can be exposed to flowing hot water. . Further, when the zinc 3 is eroded and dissolved by use of a boiler and reduced, the mounting lid 5 can be attached and detached to attach a new zinc 3.

Here, a boiler according to the present invention has a can body 2 for boiling a seawater in which a hot water flue pipe 1 made of steel or stainless steel is disposed and a hot water chamber 9 formed around the flue pipe 1 is passed. Inside, zinc 3 to be eroded and dissolved by the seawater is attached. Inside the smoke pipe 1 made of a hard steel material such as stainless steel, fire smoke from the burner passes, and seawater flows into the water heater chamber 9 on the outer periphery, and this seawater is heated. As a result, the highly soluble zinc 3 is eroded and dissolved. At this time, since the ion electrons of seawater first flow toward the zinc 3 having a low potential as electricity, the flow of ion electrons in the seawater in the can 2 is reduced, and a smoke tube made of steel or stainless steel is used. The flow of electricity to 1 becomes difficult to be performed, and the smoke tube 1 is prevented from being eroded and dissolved to prevent perforation.
A hot water smoke tube 1 made of steel or stainless steel is disposed inside, and a hot water chamber 9 is formed around the smoke tube 1. A boiler structure is provided in which zinc 3 that corrodes and dissolves by seawater is attached to a can 2 that boils seawater into the water heating chamber 9. The inside of the smoke pipe 1 made of a hard steel material such as stainless steel is ignited by a burner, and seawater is supplied to the outer water heating chamber 9 to flow and warm the seawater. As a result, the highly soluble zinc 3 is eroded and dissolved. At this time, since the electricity of the seawater easily flows to the zinc 3, the flow of ion electrons or electricity in the seawater in the can 2 is reduced. Therefore, the flow of electricity to the smoke tube 1 made of steel or stainless steel is reduced, and the smoke tube 1 is prevented from being eroded and dissolved to prevent perforation.

  A mounting port 4 is formed in a part of the can body 2 and zinc 3 is mounted inside a mounting lid 5 that closes the mounting port 4. The zinc 3 is easily attached from the outside of the can body 2 to the inside of the hot water chamber 9 by closing the attachment port 4 formed on the outer periphery of the can body 2 with the attachment lid 5 having the zinc 3 attached to the inside. Can do.

  Zinc 3 is attached to the attachment port 4 by the attachment lid 5, a burner 14 is attached to the burner port cylinder 13, a pump hose for feeding seawater to the inlet 11 is connected, and a drain hose, a nozzle, etc. are connected to the outlet 12. Then, while boiling, the hot water sprayed from this nozzle is sprayed onto the aquaculture netting tool for cleaning work. When the flame by the burner 14 is injected into the combustion chamber 6, the flame flows from the combustion chamber 6 through each smoke pipe 1 to the exhaust chamber 8 and is exhausted from the chimney 7. On the other hand, the seawater flowing in from the inlet 11 is heated at the outer peripheral portion of each smoke pipe 1 through the hot water chamber 9 to the outlet 12 and flows out as hot water.

  When seawater flows in the boiling chamber 9 in the can body 2, the ion electrons generate an electric flow according to the potential difference high and low, and then flow preferentially toward the low potential zinc 3 side. Zinc 3 is subjected to electrolytic action and is eroded and dissolved. For this reason, the number of ion electrons in the seawater is reduced, and the flow of electricity to the smoke pipe 1 made of steel, stainless steel or the like, the can body 2 or the like is reduced, and the erosion dissolution of the smoke pipe 1 or the like is reduced. Even if the seawater flows in this manner, the solubility of the zinc 3 is high and easy, so the zinc 3 reduces the flow of electricity in the seawater and erodes and dissolves the stainless steel smoke pipe 1 and the can 2. The perforation of these smoke pipes 1 and cans 2 is prevented. When zinc 3 is dissolved and reduced by boiling water, the mounting lid 5 is removed from the mounting port 4 with the seawater in the can 2 discharged from the drain port 19, and the zinc behind the mounting lid 5 is replaced with new zinc. 3, and is attached to the attachment port 4 so as to be closed by the attachment lid 5.
