Description

Как известно, основными операци ми, оказызающими вли ние на производительность сахарных заводов,  вл ютс  очистка и фильтрование сахарных растворов.As it is known, the main operations affecting the productivity of sugar factories are the cleaning and filtering of sugar solutions.

В последние годы дл  фильтрации сахарных растворов начали примен ть установки с пористой керамиковой фильтрующей поверхностью в виде вертикальных полых труб («свечей) или в виде вертикальных керамиковых -элементов с желобчатыми углублени ми по образующим, обвитых снаружи частой проволочной спиралью (фильтры Стеллара).In recent years, installations with a porous ceramic filtering surface in the form of vertical hollow tubes ("candles") or in the form of vertical ceramic elements with grooved depressions along the forming wires entwined outside with frequent wire helix (Stellar filters) began to be used to filter sugar solutions.

В таких установках в качестве фильтрующего сло  примен етс  пористый порощок, предварительно нанесенный на поверхность элементов , обладающий достаточно высокой пористостью и способный задерживать коллоидные частицы. Такой порощок обеспечивает высокое качество фильтруемых через него растворов.In such installations, a porous powder, previously deposited on the surface of the elements, which has a sufficiently high porosity and is capable of trapping colloidal particles, is used as a filtering layer. Such powder provides high quality of solutions filtered through it.

Эти установки дл  фильтровани  отличаютс  относительно небольщими размерами и достаточно производительны. Применение фильтрующей ткани в них не требуетс .These filtration plants are relatively small in size and sufficiently productive. The use of filter cloth is not required.

Фильтрующие порощки обычно получают из диатомитов-породы, состо щей из опалового кремнезема (SiO2-nH2O). Однако порощки, приготовленные из необработанного диатомита, не обеспечивают достаточной скорости фильтровани . Дл  повыщени  их качества необходима предварительна  обработка карьерного диатомита.Filtering powders are usually derived from rock diatomites consisting of opal silica (SiO2-nH2O). However, powders prepared from untreated diatomite do not provide sufficient filtration speed. To improve their quality, preliminary treatment of quarry diatomite is necessary.

Известные технологические процессы приготовлени  фильтрующих порощкоз сложны и недостаточно производительны.The known technological processes of preparing filtering powders are complex and not sufficiently productive.

Так, в книге К. Кальвертом «Диатомиты описана следующа  технологи  приготовлени  порошка: отстаивание водной суспензии диатомита в течение 24 час, фильтраци , высушивание, добавление поваренной соли и прокаливание. Расход соли при этом методе довольно -высок: 6-7% к весу диатомита.Thus, in the book of K. Calvert, Diatomites, the following technology of powder preparation is described: settling of an aqueous suspension of diatomite for 24 hours, filtering, drying, adding salt and calcining. Salt consumption with this method is quite high: 6-7% by weight of diatomite.
