Description
Изобретение относитс к способам осветлени жидкости вибрацией и может быть использовано , например, дл выделени взвешенных веществ из сточной воды.The invention relates to methods for fluid clarification by vibration and can be used, for example, for separating suspended solids from wastewater.
Известен способ осветлени жидкости вибрацией в отстойнике, причем вибратор установлен в верхнем слое жидкости. Осветление в этом случае происходит только в области расположени вибратора. Жидкости, содержащие взвешенные вещества с удельным весом, близким к удельному весу жидкости, почти не осветл ютс .There is a known method for clarifying a liquid by vibration in a settling tank, the vibrator being installed in the upper liquid layer. The clarification in this case occurs only in the area of the vibrator location. Liquids containing suspended solids with a specific gravity close to that of the liquid are almost not clarified.
С целью удалени из жидкости взвешенных веш,еств с удельным весом, близким к удельному весу жидкости, предлагаетс вибрацию осуществл ть через дно отстойника с частотой 15-55 гц и ускорением 3-15 g.In order to remove suspended matter from the liquid with a specific gravity close to that of the liquid, it is proposed to vibrate through the bottom of the settler with a frequency of 15-55 Hz and an acceleration of 3-15 g.
Способ осуществл ют в аппарате, изображенном на чертеже.The method is carried out in the apparatus shown in the drawing.
Аппарат представл ет собой емкость 1, к дну которой подведен вибропривод 2.The apparatus is a capacitance 1, to the bottom of which the vibration drive 2 is brought.
Емкость установлена на амортизаторах 3 и имеет патрубки 4, 5 tfi 6 соответственно дл входа загр зненной жидкости, дл выхода осветленной жидкости и дл выпуска осадка.The tank is installed on the shock absorbers 3 and has nozzles 4, 5 tfi 6, respectively, for the input of contaminated liquid, for the output of the clarified liquid and for the discharge of sediment.
После заполнени емкости осветл емой жидкостью ее нодвергают вибрации преимущественно с частотой 15-55 гц и ускорением 3-15 g. Под действием вертикальных вибраций взвешенные вещества оседают на дно.After the container is filled with a clarified liquid, its vibrations are predominantly vibrated with a frequency of 15-55 Hz and an acceleration of 3-15 g. Under the action of vertical vibrations suspended solids settle to the bottom.
Осадок периодически выпускают через патрубок 6.The precipitate is periodically released through the pipe 6.
Пример 1. Осветл ют сточную жидкость, содержащую взвещенные вещества в количестве 350 мг/л. В результате вибрации при частоте 50-55 гц и ускорении 8 g в течение 2 мин концентраци взвешенных веществ снижаетс до 202 мг/л. Аналогичного снижени содержани взвещенных веществ при гравитационном отстаивании достигают за 3 час.Example 1: Clarify waste liquid containing powdered substances in an amount of 350 mg / l. As a result of vibration at a frequency of 50–55 Hz and an acceleration of 8 g for 2 min, the concentration of suspended solids decreases to 202 mg / l. A similar decrease in the content of caged substances during gravitational sedimentation is reached in 3 hours.
Пример 2. Осветл ют соленую воду с плотностью 1,05 г/см, содержащую взвешенные частицы полистирола с размерами 0,8- 20 мм и уд. в. 1,008 г1см. Вибрацию осуществл ют при частоте 45 гц и ускорении 13 g в течение 3 мин. В результате 30% взвешенных веществ переходит в осадок. После 1 час 10 мин отстаивани в осадок переход т все взвешенные частицы. В услови х гравитационного отстаивани осаждени не происходит.Example 2. Clarify salt water with a density of 1.05 g / cm containing suspended particles of polystyrene with dimensions of 0.8-20 mm and beats. at. 1,008 g1sm. Vibration is performed at a frequency of 45 Hz and an acceleration of 13 g for 3 minutes. As a result, 30% of suspended solids goes to sediment. After 1 hour and 10 minutes of settling, all suspended particles are transferred to the sediment. Under the conditions of gravitational upholding, precipitation does not occur.
Предмет изобретени Subject invention
Способ осветлени жидкости вибрацией в отстойнике , отличающийс тем, что, с целью удалени из жидкости взвешенных веществ с удельным весом, близким к удельному весу жидкости, вибрацию осуществл ют через дно отстойника с частотой 15-55 гц и ускорением 3-15 g.A method for clarifying a liquid by vibration in a settling tank, characterized in that, in order to remove suspended substances from a liquid with a specific weight close to that of a liquid, vibration is carried out through the bottom of the settling tank with a frequency of 15-55 Hz and an acceleration of 3-15 g.
