Abstract

A waste oil processing plant characterised by being one which will automatically blend waste oil with kerosene to produce a fuel suitable for diesel engines and burners. A plant may be made up of three reservoirs containing respectively Waste Oil-Kerosene, and Processed Fuel. Through an all-automatic process inherent in its design the plant will pump waste oil and kerosene through a series of cleaning and polishing filter elements and blend the two fluids at a pre-set ratio to each other in order to produce a fuel suitable for Diesel engines and burners.

Description

THE DF1 WASTE OIL PROCE 3 SING PLANT The invention relates to apparatus, called DF1, for converting waste oil into a Diesel fuel substitute. The DF1 fuel produced can be used in all types of Diesel engines and burners.
The waste oil can be engine crankcase oil, or hydraulic oil, or a mixture of the two. The process involves filtering waste oil and blending it with kerosene. The machine will mix approximately four parts of waste oil to one part kerosene and can produce six hundred litres of DF1 fuel per hour.
Waste oil is poured into the main tark and is strained before being pumped through a triple filtration system. The kerosene in turn is filtered to the same st;sndard and then the two fluids pass through a series of valves, regulators and meters before being mixed together at the correct ratio. The blended fuel will then pass through a water separation unit and final polishing filter before being pumped into the fuel tank.
Automatic sensors ensure that the machine will shut itself off if the fuel tank is full, or if the waste oil, or kerosene tanks are empty. The apparatus will also switch itself off when filters require changing. In all cases lights on a control panel will indicate the reason for the machine shut down. An embodiment of the invention is described below with reference to the accompanying drawing.
As shown in the drawing, Figure 1, the apparatus consists of a waste oil tank 1, a kerosene tank 19 and a fuel tank 24. A process control unit 31 incorporates a power supply socket, a power on/off switch, a motor start button, a load/discharge switch, relays, a pressure sensor, an electronic control unit, a circuit breaker, fuses, annunciatst lamps and a flow rate indicator.
An electric motor drives a waste oil pump 4 and a kerosene pump 15. Waste oil is drawn from the tank 1 through a valve 2 and a suction strainer 3 to the pump 4. The waste oil passes through the primary filters 5 and the pressure is measured by gauge 6.
From the primary filter 5, waste oil is pumped through a positive displacement flow meter 7, to a secondary filter 8 where the pressure is measured by gauge 9. After passing through the secondary filter 8, waste oil is delivered through a flow control valve 10 and a non-return valve 11. By operating the flow control valve 10 the rate of flow through the flow meter 7 can be adjusted to the required setting.
Simultaneously kerosene is drawn from the tank 12 through a valve 13 and suction strainer 14 to the pump 15, from which it is delivered through a non-return valve 16, to a filter 17, where the pressure is measured by gauge 18. The kerosene is pumped from the filter 17 through a flow control valve 19, to a flow meter 20. By operating the flow control valve 19, the rate of flow through the flow meter 23 can be adjusted to the required setting.
The waste oil passing through the non-return valve 11 and the kerosene passing through the flow meter 20 are mixed and delivered to a water separator 21, which is provided with an air release valve 22. The oil and kerosene mixture passes from the water separator 21 into a final polishing filter 23 and then into the fuel tank 24. The fuel is drawn from the fuel tank 24 by a discharge pump 25 and monitored by a discharge counter and totaliser meter 26.
Float switches 27 and 28 are provided on the kerosene 12 and waste oil 1 tanks respectively and come into operation when the tanks are empty. A float switch 32 oz the fuel tank 24 comes into operation when the fuel tank is full. Drain taps 29 and 30 are provided on the kerosene 12 and waste oil 1 tanks respectively.
The machine is operated as follows: The waste oil and kerosene tanks a.-e loaded and the power supply is connected. The power is switched on and the motor is started. With the pumps running the waste oil and kerosene flow control valves are adjusted to the correct settings and the machine will continue to produce fuel automatically until the fuel tank is full, when the machine will switch itself off. The fuel must then be discharged before fuel production can continue. This process can be repeated until either the kerosene or waste oil tanks are empty. The tanks must then be refilled before further fuel production is possible.
When the primary filters become blocked the resultant pressure will operate a pressure sensor, which will switch the machine off. A lamp on the control panel will indicate that the filters should be replaced.
The DF1 machine is designed as a transportable unit for batch production as above, but however it can also be installed permanently on site to provide continuous fuel production.
Since lubricating oils and Diesel type gas oils have very similar paraffinic bases, the DF1 produced fuel is suitable for use in all diesel engines for any mode of operation. The physical properties of this fuel are equal to and in some cases exceed British Standard Specifications for Diesel fuel. The DF1 fuel has also some highly beneficial properties not found in conventional Diesel fuel, i.e. the lubricating and sealing properties of DF1 fuel and the absence of waxing at low ambient temperatures. The calorific value of DF1 fuel is equal to Diesel fuel and there is no loss tf performance or power output.
