Description
(54) СПОСОБ ПРЕДОТВРАЩЕНИЯ ОБРАЗОВАНИЯ НАКИПИ(54) METHOD FOR PREVENTING SCALE FORMATION
ры способствуют интенсивной направленной кристаллизации.Rays promote intensive directional crystallization.
Пример. Опыты провод т в три серии, в режимах, .имитирующих: услови способа. Солесодержание исходной воды 8,3 г/л. Количество CaSO в исходЬой воде 4,15 г/л.Example. The experiments were carried out in three series, in modes that imitate: conditions of the method. The salt content of the source water is 8.3 g / l. The amount of CaSO4 in the outgoing water is 4.15 g / l.
Перва сери . Контрольный опыт. Пробу воды (1 л) нагревают до 95 С и термостатируют при этой температуре в течение-1 ч. Определ ют содержание CaSO. в фильтровальном растворе .First series Test experience. A sample of water (1 L) is heated to 95 ° C and thermostatic at this temperature for 1 hour. The content of CaSO4 is determined. in filter solution.
Втора сери . В исходную воду (1 л помещаю.т Na-соль карбоксиметилцеллюлозы {КМО в количестве 5 мг/л (вариант А) и н-гептиловый спирт в количестве 15 мг/л (вариант Б), пробы нагревают до 95°С, термостатируют в течениечаса. Определ ют содержаниеCaSO в фильтровальном растворе. The second series. In the initial water (1 l I put. T Na-carboxymethylcellulose salt {KMO in the amount of 5 mg / l (variant A) and n-heptyl alcohol in the amount of 15 mg / l (variant B), the samples are heated to 95 ° C, thermostatic in CasO in the filter solution.
Треть сери . В исходную воду ввод т 5 мг/л Na-соль карбоксиметилцеллюлозу (вариант А) и н-гептиловыйThird series. 5 mg / l of carboxymethylcellulose Na-salt (variant A) and n-heptyl
спирт-15 мг/л (вариант Б), пробы нагревают до 95°С и термостатируют в течение часа, после чеговоду обрабатывают ультразвуковым полем в кавитационном режиме при частоте 20 кГц в течение 30 с. Определ ют содержание CaSO в фильтровальном растворе.alcohol-15 mg / l (option B), samples are heated to 95 ° C and thermostatic for an hour, after chego water are treated with an ultrasonic field in a cavitation mode at a frequency of 20 kHz for 30 s. The CaSO content in the filter solution is determined.
Введение различных ПАВ стабилизирует пересыщение по сернокислому кальцию и при термообработке в течениа, 1 ч отложений на стенках не наблюдаетс . При длительном сто нии в частичном упаривании снимаетс пересыщение и стенки постепенно зарастают гипсом.The introduction of various surfactants stabilizes the supersaturation of calcium sulfate and during heat treatment for a period of 1 hour no deposits on the walls are observed. With prolonged standing in partial evaporation, supersaturation is removed and the walls gradually overgrow with gypsum.
При наложении ультразвука в стабилизированных пересыщенных растворах наблюдаетс интенсивна кристаллизаци с образованием тонкодисперсного порошка без накипеобразовани . Остаточна концентраци солей жесткости в растворах при дальнейшей термообработке последних также не дает накипеобразовани .When applying ultrasound in stabilized supersaturated solutions, intense crystallization is observed with the formation of fine powder without scale formation. The residual concentration of hardness salts in solutions with further heat treatment of the latter also does not scale up.
Результаты опытов даны в таблице.The results of the experiments are given in the table.
