Description

Дл  предохранени  поверхности котлов от отложени  на ней накипи примен етс  преимущественно тринатрий фосфат и каустик. Однако эти средства, облада  хорошими антинакипкыми качествами, в то же врем  активно вспенивают котловую воду, что ведет к ухудшению качества пара и, следовательно, к увеличению расхода топлива. Вспенивание и унос воды  вл ютс  причиной загр знени  пароперегревательных элементов и образовани  нагара в золотниках м цилиндрах паровых машин, вызыва  необходимость более частой их продувки.To protect the boiler surface from scale deposits on it, predominantly trisodium phosphate and caustic are used. However, these tools have good anti-boiling qualities, at the same time actively foaming the boiler water, which leads to a deterioration in the quality of steam and, consequently, to an increase in fuel consumption. Foaming and entrainment of water cause fouling of steam superheater elements and the formation of soot in the spools and cylinders of steam engines, necessitating their more frequent blowing.

описываетс  способ внутрикотловой обработки воды с применением антинакипных средств. Отличительна  особенность этого способа состоит в том, что, с целью снижени  вспенивани  и уноса воды, з поступающую в котел воду добавл ют известь (гашеную или негашеную ) или известь в смеси с содой или фocфaтoJM. describes a method of intra-boiler water treatment using anti-scale agents. A distinctive feature of this method is that, in order to reduce foaming and entrainment of water, lime (slaked or unslaked) or lime mixed with soda or juice is added to the water entering the boiler.

Способность извести к пеногашению объ сн етс  специфическим свойством-иона кальци  укрупн ть мелкодисперсную 11звесть, благодар  чему снижаетс  вспенивание и унос котловой воды без ухудшени  антинакипных свойств смеси.The ability of lime to defoaming is explained by the specific property of calcium ion to enlarge finely dispersed lime, thereby reducing the foaming and entrainment of boiler water without degrading the anti-scale properties of the mixture.

В зависимости от качества воды и содержащихс  в ней вешеств дл  снижени  вспенивани  примен ют одну известь или известь в смеси с содой или с фосфатом. Так, при большой временной жесткости воды и малой посто нной жесткости примен ют одну известь, при значительной посто нной жесткости воды лучшие результаты дает применение извести с содой и, наконец, при большом содержании в воде сульфатов примен ют известь с фосфатом, так как фосфат в этом случае преп тствует отложению гипсовой накипи.Depending on the quality of the water and the substances it contains, one lime or lime in a mixture with soda or with phosphate is used to reduce foaming. So, with a large temporary hardness of water and a small constant hardness, one lime is used, with a significant constant water hardness, the use of lime with soda gives the best results, and finally, with a high content of sulfates in water, lime with phosphate is used, since phosphate in In this case, it prevents the deposition of gypsum scale.

Предмет изобретени Subject invention

Способ внутрикотловой обработки воды с применением антинакипных средств, отличающийс  тем, что, с целью снижени  вспенивани  и уноса воды, в поступающую в котел воду добавл ют известь (гашеную или негашеную) или известь в смеси с содой или фосфатом.A method of intra boiler water treatment using antiscale agents, characterized in that, to reduce foaming and water carryover, lime (slaked or unslaked) or lime in a mixture with soda or phosphate is added to the water entering the boiler.
