Сепаратор СТЭТ-бу параллель пластины электростатического сепаратор. Әмма, the electrode plates are oriented horizontally as opposed to vertically, as is the case with most parallel plate separators. Моннан тыш,, the STET separator accomplishes the particle turbo-charging and conveying simultaneously by a high-speed open mesh conveyor belt. This feature allows for both a very high specific processing rate of feed and the capability to process powders much finer than conventional electrostatic devices.
The mineral separator machinery has been in commercial operation since 1995, отделяя несгоревшего углерод берсе золы-уноса минераль матдәләр (типичный Д50 якынча 20 мкм) анда ташкүмер электростанций. This electrostatic separation machine has also been successful at beneficiating other inorganic materials, including minerals such as карбонат кальций , тальк, барит, һәм башка. The STET separator has also been successfully applied to processing agricultural materials such as oilseed meals and pulses, animal meals, and rendering products.
The fundamental details of the STET separator are illustrated below. Частицы заряжаются хисабына трибоэлектрического китергәннәр аша частиц столкновений " зазор арасында электродами. The applied voltage between the electrodes is between ±4 and ±10 kV relative to the ground, давая барлык көчәнеш перепад 8 – 20 кв бик тар межэлектродном промежутке номинально 1.5 см (0.6 дюйма). Feed particles are introduced to the electrostatic separation machine at one of three locations (Порты Ашатырга ).
The electrostatic separation machine produces only two products: a negatively charged particle stream collected on the positively charged electrode and a positively charged particle stream collected on the negatively charged electrode. The products are conveyed to the respective hoppers at each end of the electrostatic separation machine by the separator belt and fall out of the separator by gravity. The machine does not produce a middlings or recycle stream, хәер, многопроходная конфигураций яхшырту өчен чисталык продукт һәм/яки торгызуга возможны.
Частицы тапшырыла аша зазор электрода (зона аеру ) буенча непрерывному циклу, ачык сетка поясы. Пояс эшли, югары тизлек. Геометрия ремень өчен хезмәт итә зачистки вак частиц белән өске электродов, preventing the accumulation of fine particles that degrades the performance and voltage field of traditional free-fall parallel plate-type electrostatic separation machines. Моннан тыш,, пояс булдыра югары чиста, зонасына югары турбулентлык арасында ике электродами, promoting turbo-charging. The counter-current travel of the separator belt allows for continuous charging and re-charging of particles within the separator, eliminating the need for a pre-charging system upstream of the machine.
The electrostatic separation machine is a high feed rate, икътисади яктан нәтиҗәле эшкәртү системасы . The maximum processing capacity of the machine is mostly a function of the volumetric feed rate that can be conveyed through the electrode gap by the separator belt. Башка переменные, кебек хәрәкәт тизлеге тасмалар таратканнар, the distance between the electrodes, and the aerated density of the powder, affect the maximum feed rate, кагыйдә буларак, меньшей дәрәҗә.
Өчен чагыштырмача югары плотности материаллар, such as летучая көл, the maximum processing rate of a 42-inch (106 см) electrode-width commercial separation unit is roughly 40 – 45 Тонна комбиазык сәгате. Өчен ким плотных материаллар , максималь тизлеге бирү түбәнрәк.
| Feed Material | Approximate Compacted Bulk Density | Approximate STET 42 Inch Separator Maximum Feed Rate |
|---|---|---|
| Пепел | 60 – 80 pound/ft 3 (1000 –1300 kg/m3) | 40 – 45 Ton per hour |
| Тальк | 30 – 40 pounds/ft 3 (500 – 600 kg/m3) | 15 – 20 Ton per hour |
| Wheat Flour | 30 – 40 pounds/ft 3 (500 – 600 kg/m3) | 15 – 20 Ton per hour |
The STET separator provides end users with adjustable control of product quality and can be integrated into existing process flowsheets. Моннан тыш,, the STET separator has multiple automation options:
STET currently offers two sizes of the STET separator:
This machine is approximately 9.1 метрдан (29 feet, 11 ¾ inches) озак; 1.7 метрдан(5 feet, 7 дюймов) киң; 3.2 метрдан (8 feet 1 7/8 дюймов) югары. The compactness of the system allows for flexibility in installation designs and processes up to 40 tonnes per hour for fly ash.
Электр энергиясе якын тәшкил итә 1 kilowatt-hour per tonne of material processed, with most of the power consumed by the two 50 HP (37 kW) motors that drive the belt.
This machine is approximately 9.1 метрдан (29 feet, 11 ¾ inches) озак; 1.2 метрдан(4 feet 1 дюйма) киң; 3.2 метрдан (8 feet 1 7/8 дюймов) югары, making it 18” narrower than or 42” model, and is able to process up to 23 feed tons per hour.
