Изобретение относитс к области химической очистки теплообменной аппаратуры.This invention relates to the field of chemical cleaning of heat exchange apparatus.
Известны растворы дл химической очистки теплообменной аппаратуры, содержащие сол ную кислоту и ингибиторы.Solutions for the chemical purification of heat exchange apparatus containing hydrochloric acid and inhibitors are known.
Однако они не могут быть использованы одновременно дл поверхностей, изготовленных из углеродистых и нержавеющих сталей и изготовленных из титана и его сплавов.However, they cannot be used simultaneously for surfaces made from carbon and stainless steels and made from titanium and its alloys.
В предложенном растворе концентраци сол ной кислоты составл ет 75-110 г/л, а в качестве ингибиторов введены лаурилпиридиний сульфат 0,5-1,5 г/л, уксусный альдегид 8- 25 г/л, йодистый калий 0,1-0,3 г/л, сернокислый титан 30-50 г/л и смесь полиэтиленгликолевых эфиров моно- и диалкилфенолов (ОП-10) 0,1-0,2 г/л.In the proposed solution, the concentration of hydrochloric acid is 75-110 g / l, and as inhibitors, laurylpyridinium sulfate 0.5-1.5 g / l, acetic aldehyde 8-25 g / l, potassium iodide 0.1-0 , 3 g / l, titanium sulfate 30-50 g / l and a mixture of polyethylene glycol ethers of mono- and dialkylphenols (OP-10) 0.1-0.2 g / l.
Такой раствор защищает от коррозии и удал ет накипь из теплообменной аппаратуры.Such a solution protects against corrosion and removes scale from the heat exchangers.
