The STET separator is a parallel plate electrostatic separator, ach, the electrode plates are oriented horizontally as opposed to vertically as is the case in most parallel plate separators. ina theannta sin, the STET separator accomplishes the particle tribo-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, chomh maith leis an gcumas a phróiseáil púdair i bhfad níos míne ná feistí leictreastatach traidisiúnta. The mineral separator machinery has been in commercial operation since 1995 scaradh carbóin unburned ó mhianraí fuinseog eitilt (D50 tipiciúil thart 20 m) i stáisiúin chumhachta guail-fired. This electrostatic separation machine has also been successful at beneficiating other inorganic materials, lena n-áirítear mianraí, mar shampla carbónáit chailciam, talc, barite, agus Daoine eile. 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. The particles are charged by the triboelectric effect through particle-to-particle collisions within the gap between the electrodes. The applied voltage between the electrodes is between ±4 and ±10 kV relative to ground, giving a total voltage difference of 8 - 20 kV across a very narrow electrode gap of nominally 1.5 cm (0.6 orlach). Feed particles are introduced to the STET separator at one of three locations (Feed Ports). The STET separator produces only two products, sruth na gcáithníní lucht diúltach a bailíodh ar an leictreoid atá luchtaithe go deimhneach, agus sruth na gcáithníní luchtaithe go deimhneach a bailíodh ar an leictreoid diúltach. The products are conveyed to the respective hoppers at each end of the STET separator by the separator belt, and fall out of the separator by gravity. Ní dhéanann an deighilteoir STET tháirgeadh meánaigh nó sruth athchúrsáil, cé go bhfoirmíochtaí pas il chun feabhas a chur ar íonachta táirge agus / nó aisghabháil is féidir a dhéanamh.
Cáithníní a in iúl tríd an bhearna leictreoid (crios scaradh) ag lúb leanúnach, crios mogalra oscailte. Feidhmíonn an crios ag luas ard. An geoiméadracht an crios ag freastal a sweep cáithníní fíneáil as an dromchla na leictreoidí, preventing the accumulation of fine particles that degrades the performance and voltage field of traditional free fall parallel plate type separation devices. Freisin, Gineann an crios a fórsa ard, crios suaiteacht ard idir an dá leictreoidí, a chur chun cinn tribo-mhuirearú. Ceadaíonn an taisteal frith-reatha an crios deighilteoir do mhuirearú leanúnach agus ath-mhuirearú nó cáithníní laistigh den deighilteoir, deireadh leis an ngá atá le córas réamh-mhuirearú in aghaidh srutha ar an deighilteoir STET. Is é an deighilteoir STET ráta beatha ard, Córas próiseála cruthaithe ó thaobh na tráchtála. Is é an cumas próiseála uasta na deighilteoir STET den chuid is mó feidhm de chuid an ráta beatha toirtmhéadrach is féidir a chur in iúl tríd an bhearna leictreoid ag an crios deighilteoir STET. athróga eile, cosúil leis an luas an crios, an t-achar idir na leictreoidí agus an dlús aeraithe an púdar éifeacht ar an ráta beatha uasta, de ghnáth go pointe níos lú. For relatively high density materials, for example fly ash, an ráta a phróiseáil uasta 42 orlach (106 cm) Is leithead leictreoid aonad scartha tráchtála thart 40 - 45 Tonna in aghaidh na huaire beatha. I gcás ábhar beatha níos lú dlúth, Is é an ráta beatha uasta níos ísle.
| Feed Material | Approximate Compacted Bulk Density | Approximate STET 42 Inch Separator Maximum Feed Rate |
|---|---|---|
| Cuil Ash | 60 - 80 pound/ft 3 (1000 –1300 kg/m3) | 40 - 45 Ton per hour |
| talc | 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. Freisin, the STET separator has multiple automation options:
STET currently offers two sizes of the STET separator:
This machine is approximately 9.1 méadar (29 cosa, 11 ¾ inches) fada; 1.7 méadar(5 cosa, 7 orlach) ar fud an; 3.2 méadar (8 cosa 1 7/8 orlach) ard. The compactness of the system allows for flexibility in installation designs and processes up to 40 tonnes per hour for fly ash.
Is é an tomhaltas chumhacht faoi 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 méadar (29 cosa, 11 ¾ inches) fada; 1.2 méadar(4 cosa 1 orlach) ar fud an; 3.2 méadar (8 cosa 1 7/8 orlach) ard, making it 18” narrower than or 42” model, and is able to process up to 23 feed tons per hour.
Is é an tomhaltas chumhacht faoi 1 kilowatt-hour per tonne of material processed, with most of the power consumed by the two 30 HP (22KW) motors that drive the belt.
