Description

[Detailed Description of the Invention] The present invention relates to an emulsion fuel generation device using waste oil.

Currently, a wide variety of oils, including lubricating oils for various engines and machine tools, cutting oils for machining, cooling oils for cooling processed products, etc., are contaminated with dirt, dust, rainwater, or thermally decomposed as a result of long-term use. When the oiliness of oil decreases due to physical and chemical factors such as these, and it can no longer fulfill its role, it is incinerated as waste oil, but the energy generated during incineration is wasted without being used.

Also, the transportation and incineration costs for disposal are not trivial.

However, although the oiliness of such waste oil has decreased, the calorific value (calories) during combustion has not decreased significantly.

However, until now, no effective system for converting this waste oil into emulsion fuel has been proposed.

Therefore, it is an object of the present invention to provide an emulsion fuel generation device using waste oil, which aims to effectively utilize this waste oil.

This invention connects heavy oil and other oil tanks, waste oil tanks, and if necessary, these and water tanks to a static mixer through pumps, and continuously injects the emulsion stabilizer tank and stabilizer into the static mixer. A mixing oil tank with connected pumps is installed, and a level gauge is installed on the mixing oil tank to enable control of the start and stop of each pump, and a continuously variable transmission is connected to the pump to adjust the discharge volume of each pump. This is an emulsion fuel generation device that uses waste oil.

The present invention can be used for various purposes, and as an example, the case where it is applied to a boiler using heavy oil will be explained with reference to the drawings.

In the figure, 1 is a heavy oil tank, 2 is a water tank, and 3 is a waste oil tank.

4 is a static mixer, which usually has a twisted blade element inserted into a pipe.

The static mixer 4 includes a heavy oil pump 5, a water pump 6,
It is connected to a heavy oil tank 1, a water tank 2, and a waste oil tank 3 via a waste oil pump 7, respectively.

Of course, if water is not mixed, the water tank 2 and water pump 6 are unnecessary.

Several strainers will be installed on the suction side of each pump as necessary to prevent pump wear and accidents.

5a, 6a, and 7a are flowmeters.

8 is a continuously variable transmission with a motor, and 9, 10, and 11 are continuously variable transmissions that are successively installed in the continuously variable transmission with a motor 8.

12.13 is a fixed coupling that connects the continuously variable transmission,
Reference numeral 14 denotes a removable clutch, which is used to prevent power consumption due to idling of the continuously variable transmission 11 when waste oil is difficult to obtain at all times.

As the continuously variable transmission, a chain type or a bell type is usually used.

15, 16, and 17 indicate chains wound between the continuously variable transmission and each pump.

Reference numeral 18 denotes a mixed oil tank, which is installed following the static mixer 4 and stores the oil that has been stirred and mixed in the static mixer 4 and sent.

One is an emulsion stabilizer tank, and 20 is a stabilizer pump, which is connected to the mixing oil tank 18 or the inlet of the static mixer 4, or both.

A level gauge 21 may be installed in the mixed oil tank 18.

The level gauge 21 senses the upper and lower limits of the amount of oil in the mixed oil tank 18, and stops the operation of the heavy oil pump 5, water pump 6, waste oil pump 7, and stabilizer pump 20 at the upper limit, and stops the operation of the heavy oil pump 5, water pump 6, waste oil pump 7, and stabilizer pump 20 at the lower limit. enable to operate.

Furthermore, it is desirable to install a pump 22 with a static mixer in the mixed oil tank 18 to maintain the mixed oil in a perfect state at all times.

23 is a flow meter, 24 is a boiler parser pump, and 25 is a direct connection pipe that directly connects the heavy oil tank 1 and the boiler burner pump 24.

To explain the operation of the present invention, first, the continuously variable transmission is adjusted, and the discharge amounts of the heavy oil pump 5, water pump 6, and waste oil pump 7 are adjusted according to the flow meters 5a, 5a, and 7a, and the heavy oil, water, and waste oil are mixed. Determine the ratio.

When the motor of the motor-equipped continuously variable transmission 8 is driven, heavy oil, water, and waste oil are discharged in fixed amounts from each pump and sent to the static mixer 4, where they are mixed and agitated and used for the boiler. It is stored in the mixed oil tank 18 as emulsion fuel.

Also, a stabilizer pump 20 is installed in the mixed oil tank 18 at the same time.
The emulsion stabilizer is supplied and mixed into the mixed oil.

The mixed oil in the mixed oil tank 18 is transferred to the pump 2 with a mixer.
2, the emulsion fuel is constantly circulated and stirred to maintain its complete state as an emulsion fuel.

When the level gauge 21 is installed, the pump is automatically activated and stopped, and no oil leakage or fuel shortage occurs in the mixed oil tank 18.

In addition, by removing the removable clutch 14, it is possible to use only heavy oil and water, or by stopping the motor and connecting the direct connection pipe 25.
By opening the valve, only heavy oil can be used.

Next, experimental data for combustion in a boiler of emulsion fuel produced by the generation device according to the present invention will be shown.

The waste oil used here is mainly from ship bilge.

As shown in Table 2 below, the calorific value of the emulsion fuel mixed with the waste oil is close to that of heavy oil only, and there is no inferiority in exhaust gas or combustion efficiency, confirming that it is suitable as a fuel.

The present invention is as described above, and because it enables the effective use of waste oil that was conventionally discarded as useless, it is important to note that it is considered inevitable that the price of crude oil will continue to rise in the future, and resource conservation is being called for. It is extremely useful.
