除去方法に関する。Detailed Description of the Invention (Industrial Application Field) The present invention selectively and efficiently removes only sulfate ions entering the cooling water of a diesel engine by ion exchange.
The present invention relates to a method for removing sulfate ions from diesel engine cooling water that can prevent corrosion of the cooling surface of the combustion chamber wall of a diesel engine caused by sulfate ions.

が使用さｎている。(Prior Art) Rust prevention management of the cooling system of a diesel engine is extremely important. In particular, the main cause of crack accidents seen in the cooling surfaces of combustion chamber components such as pistons, cylinder covers, and cylinder liners in high-output marine diesel engines is a decrease in strength due to material corrosion. Therefore, a rust preventive agent is added to the cooling water to prevent this corrosion. As such rust preventives, nitrites, phosphates, borates, etc. are used.

一般に硫酸イオンｔ−５０ｐｐｍ以下に抑制することが
必要とされている。However, in the case of OSE diesel engines, since friendly oil with a high sulfur content and V ratio is used as fuel, unsulfate ions generated from the nitrous acid gas generated by this combustion may mix into the cooling water. It is inevitable that it will come. This sulfate ion significantly reduces the rust prevention effect of the rust inhibitor. Additionally, the amount of sulfate ions increases with time, accelerating corrosion of the material. In order to prevent accidents due to corrosion, it is generally necessary to suppress sulfate ions to t-50 ppm or less even in cooling water containing rust preventive agents.
従って腐食防止のためには冷却水全極めて頻繁に交換し

繁な冷却水の交換は不可能である。Therefore, in order to prevent corrosion, all of the cooling water must be replaced very frequently, but fresh water is expensive for ships sailing on the open sea, and the quantity is limited, making it necessary to replace the cooling water frequently. Replacement is not possible.

等操作が煩雑である。A method of injecting alkaline earth metal and lead nitrites or hydroxides has also been proposed as a method for removing sulfate ions in cooling water containing nitrite-based rust inhibitors, but this method does not require metered dose injection. Complex devices such as pumps, chemical injection tanks, reaction tanks, and filters are required, and operations such as weighing, dissolving, and injecting chemicals are complicated.

機関冷却水の硫酸イオン除去方法である。(Ninth means for solving the problem) The present invention passes cooling water through a barium-type strongly acidic cation exchange resin to activate the effect of the rust preventive agent and capture only sulfate ions to increase the concentration of sulfate ions in the cooling water. This reduces the That is, the present invention provides for converting some or all of diesel engine cooling water containing a nitrite-based, phosphate-based, borate-based rust preventive agent, or a mixture thereof into a barium-type strongly acidic cation exchange resin tube. This is a method for removing sulfate ions from diesel engine cooling water.

The sulfate ions in the cooling water are reduced as barium sulfate, which is captured between the ion exchange resin particles, and also reacts with the rust preventive agent. It activates it.
