Description

Emulsion device of BA oil and water {THE APPARATUS OF EMULSIFYING BA OIL AND WATER}

The present invention relates to an oil-and-water emulsion apparatus directly connected to a boiler which burns the emulsion oil of the best state emulsified in a very short time. Specifically, bunker A oil, which is a fuel oil, and an liquid additive for emulsification are first mixed with an S-type mixer. After mixing the mixture with water and a mixing ejector, the emulsion was firstly emulsified into W / O type and preheated with a heat exchange type electric heater. Emulsion fuel oil is supplied from the mixing tank, the mixing pump, the D-type mixer, and the electric heater, in order to supply the oil into the emulsion tank and maintain it at a constant temperature (25-30 ° C) by the electric heater in the emulsion tank.

The present invention relates to a device for producing an emulsion fuel oil having an excellent emulsification state in an oil-and-water emulsifying device for fuel, an apparatus configuration of a circulation system for holding an emulsion fuel oil manufactured in a good state, and oil level (level) detection in a tank. The oil and water emulsion device designed to supply the emulsion oil to the boiler in a very short time by controlling the operation of the partial device by interworking with each device.

It starts at the lower level (L ') of the emulsion supply tank (T-2). When the fuel is consumed while the boiler is running, the level controller (LS 02) detects a signal and sends it to the control panel (PLC). The pump is operated to refill the emulsion fuel oil in the emulsion tank (T-1) with the emulsion supply tank (T-2), and the emulsion tank (T-1) has a volume of 40 l, which is one batch capacity, in the emulsion supply tank (T-2). As it is supplied, the level controller (LS 01) operates the lowest level (L) sensor so that the emulsion supply pump (P-3) stops and immediately signals the raw material input to the pump (P-1, P-4, P-). 5) The valve is opened and the valve (SV-01, 02, 03) is opened to perform one bet operation. The one bet process is carried out over one minute.The mixing ratio is 35.8ℓ for BA oil, 0.2ℓ for additives and 4ℓ for water. A total of 40 liters is added at the rate.

The additive injection pump (P-1) operates by adjusting the rotational speed of the DC motor between installations so that 0.2 liters are injected for 1 minute, and 0.2 liters of additives required for one batch are supplied in a fixed amount for 1 minute by the rotational speed of the pump. The additives supplied are mixed with BA oil in an S-type mixer (S-1).

When the water shutoff valve (SV-03) is opened, water is added and the injected water is mixed with fuel mixed with additives in BA oil in the mixing ejector (E-1).

The water supply pump (P-5) is operated to maintain a constant water pressure of the inlet at all times while being controlled to supply 4ℓ for 1 minute.

All the fuel oil is mixed into the mixer pump (P-2) and the emulsion oil is mixed by the D-type mixer (D-1) and the emulsion particle is 0.5- when passing through the D-type mixer (D-1) It is a highly atomized and homogeneous emulsion of 1 μm.

The burning time of one batch (40 liters) is about 5 minutes and it is designed to circulate the mixer more than 3.8 times in emulsion tank (T-1) based on the maximum boiler consumption in 5 minutes.

1 When the flow rate set in the batching operation is confirmed by the flowmeter, the pump power is turned off by the signal of the flowmeter after the closing.

That is, when all the BA oil setting values are input from the BA oil flow meter (FQA 02), the control panel (PLC) detects and cuts off the power of the BA oil supply pump (P-4).

When the additive is input from the additive flowmeter (FQA 01), the additive is sensed at the control panel and then the power supply of the additive supply pump (P-1) is cut off or linked to the BA oil flowmeter to use the BA flowmeter signal as the control signal. do.

That is, at the end of the BA oil injection, the additive injection pump P-1 is also terminated like the BA oil injection pump P-4.

If all set values are entered in the water meter (FQA 03), the control panel detects the water shut off valve (SV-3) and water supply pump (P-5) to shut off the water supply.

This allows the process to run simultaneously and stops simultaneously after one minute.

1 After the batch raw material is put in, the volume of emulsion fuel oil in the emulsion tank (T-1) flows into 40 liters and the emulsion supply tank (T-) is supplied until it is supplied to the emulsion supply tank (T-1) again according to the boiler load. 1) The emulsion fuel oil in the tank flows out from the bottom line of the tank (T-1) and the continuous mixer is passed through the circulation system through the pump (P-2), the D-type mixer (D-1), and the heater (SH-002). The cycle number is 3.8 times at the maximum load rate of the boiler. If the load rate is low, the cycle number is 3.8 times or more.

If the oil level in the emulsion supply tank is lower than the lower level (L ') by continuously consuming the emulsion fuel according to the boiler fuel consumption amount, it can be said that the oil-and-water emulsion device in which the above process is repeated.
