Abstract

Invention for processing and treating sewage, whereby drying and elimination of pathogens takes place; comprising a feed assembly with conical section and inlet tube having a discharge area and inlet area for the passage of air and sewage and a rotor for creating reverse vortices in a cyclonic air-stream within the conical section and inlet tube, wherein the invention is configurated to also create a fundamental standing wave - to assist treatment and processing of sewage - and a centripetal boundary envelope inside the conical section.

Description

2354232 SEWAGE PROCESSING TREATMIENT INVENTION This invention relates to
an apparatus that treats and processes sewage.
New legislation in many countries is making it increasingly difficult to dispose of sewage into the sea or spread it on land, due to its high content of pathogens. Currently, techniques of drying the sewage, mixed with, for example, lime to combat pathogens, are very expensive. This invention will remove some of the pathogens and dry the sewage at the same time. Market research has shown that the current cost of treatment can be dramatically reduced when using this invention. It will enable sewage companies to substantially reduce transport costs. The end product can also be used in many applications such as fertiliser or to generate electricity.
T'his novel invention has processed and treated centrifuged sewage containing 21.4% dry solids, at a rate of 4000 Kg per hour, with the expelled powdered product containing 70 to 77% dry solid, and removed at least 25 to 50% of the pathogens, due to the configuration of the invention which creates reverse vortices upstream in front of a rotor which also shears the sewage.
The resulting intense disruption, caused by the action within the reverse vortices in the cyclonic airstream, together with the shearing action of the rotor's blades, will alter the chemical structure of the sewage, for example by turning some of the water in the sewage into hydrogen peroxide. So powerful is the reverse vortex that some of the water in the sewage is separated from the solid, in the form of pure water, and returns back down the wall of the inlet tube whilst sewage is being fed in. High speed video photography has successfully recorded the existence of the reverse vortex. Powder and pure water has been seen coming back down the wall of the inlet tube. (Rocks introduced into the conical section travelled in the opposite direction to the rotor at the same time as particles near the rotor travelled in the same direction of the rotor.) This has imitated what happens inside a tornado. When a tornado hits the ground, the airstream suddenly reverses inside the tornado. (This invention may also disassociate water, create ozone to assist in reducing the smell of the sewage, create N2, comminute rocks and materials containing oxygen, whilst at the same time producing Abrikosov vortices which aid fusion.) The apparatus consists of a high speed motor attached to the rotor, a product discharge exit tube area, a specially configurated nine or ten blade rotor rotating horizontally or vertically, contained in a scrolled housing, attached to which is a conical section which slopes downwards at an angle of about 9.7 degrees attached to a feed inlet tube. The inlet tube being parallel and in line with the fan axis. The inlet tube can be mounted horizontally, or vertically with the inlet tube sucking the material upwards due to the high air velocity created by the rotor. Gravity pulling on the sewage will reduce the velocity of the sewage, allowing the reverse vortex further time to treat the sewage.
The 5 to 6mm thick blades, which may be coated to assist with any wear rate problem, lean back 5 degrees from the centre of the hub - whose diameter must not be over 10% of the diameter of the rotor - wbich also has a specially configurated interrupter attached to it - the height of which must not protrude into the conical section beyond the leading edge of the blade - the blade must not protrude into the conical section more than 14. 80/o of its maximum width- The feed in tube must have a diameter equal to one-third the diameter of the rotor and the conical section where it is attached to the housing - must be two-thirds the diameter of the rotor. The scrolled housing 2 should be as small as possible, for example a clearance of only 10mm widening to 120mm, whilst allowing for the free movement of the rotor which will have a maximum width at its top, equal to 88% of the diameter of the inlet tube. (This rotor width is reduced to only 44% by the time it reaches the hub as its configuration is such that there is a 13 degree angle on one side of the blade and a 45 degree angle on the opposite leading edge side of the blade, which shortens the width of the blade. The angle begins one-third of the length of the blade up from the hub.) The interrupter has two semi-spherical mounds side by side, one having a diameter equal to 42% the diameter of the hub, and the other 2 1%. Nfid- way up, both have a hole drilled in them, from one side to the other, that has a diameter no greater than 10% of the diameter of the hub. The discharge exit tube area will have the same area as the inlet tube diameter. The diameter of the rotor is equal to 41% of the total length of the combined conical section and inlet tube. Therefore a typical rotor diameter of 6 1 Omm will have a total feed in length of 148 1 mm. This 6 1 Omm diameter rotor configuration would require a high speed motor, typically 20OKw, that is capable of turning the rotor at a speed of 96 cycles per second (cps) and maintaining that precise speed ( to + or - I cps) under load. It is essential for the formation of the reverse vortex - and the centripetal boundary envelope within the conical section - that the inlet tube connection to the conical section, and the conical section connection to the housing in front of the rotor, is perfectly smooth to allow a smooth larninar flow. The invention also utilises a feed assembly conveyor system.
To determine the ideal configuration of the invention a formula is used to determine the ideal combined length of the inlet tube and conical section. This is because all parts of the invention are fixed in dimension in relation to the other parts. The simple formula is to divide either the speed (of the rotor, the air, or the passage of material in the air) by the frequency of either the material to be processed or the rotor. This will create a fundamental standing wave down the inlet tube that is specific to the material. When the standing wave is achieved the dimensions of all the parts can then be determined. This standing wave will also assist the treatment and processing, within the boundary envelope, inside the reverse vortex whicb in turn is situated inside the conical section.
However should the apparatus be built using, for example, a 610mm diameter rotor, the frequency may be such that a different length of feed tube would be required to suit the chosen material. The inlet tube length would then be fixed according to the standing wave created.
