The present invention relates to a combustion device for completely burning waste oil such as bunker C oil or mobile.

Known combustion burners can be roughly classified into fuel pressurized injection nozzles, rotary injection rotary burner steam, and air injection nozzles.

The above three types of burners merely atomized the liquid heavy oil even when the liquid was scattered and sprayed when pressurized the liquid middle stream (waste oil of bunker C oil).

Therefore, the microscopic observation of the atomization or atomization of the heavy oil is the combustion (oxidation) of the large particles of heavy oil mixed with air. At this time, the inside of the large particles of the heavy oil is 100% complete combustion because air (oxygen) cannot be connected. Could not have been expected.

Therefore, in the industry, dust collectors are used to collect soot or dust generated by incomplete combustion, and dust or dust is collected by this. However, it is being installed and used because it is less than the environmental standard value.

However, such a device has a lot of problems due to the enormous amount of facilities and the accompanying economic overload.

The present invention was invented to solve the above problems, the present invention is a high-temperature, high-temperature (550) by embedding a boiler for heating a high-purity water in the burner itself, the primary heating tube, the secondary heating tube, the third heating tube -600 ° C or higher) and obtains a high-temperature dry saturated steam frame and disperses it in the burner's boiler through a spray nozzle, and the dry high-temperature steam is mixed with waste oil such as heavy oil supplied from a separately installed waste oil tank. Due to the high temperature and high pressure (25-35KG / CM3) of the high temperature (25-35KG / CM3), the injection nozzle end is mixed with the air flowing from the outside under gaseous state instead of liquid atomization. After heating the primary heating tube, secondary heating tube, and tertiary heating tube installed in the burner boiler, it flows into the fire zone of the industrial boiler and enables the heating of the industrial boiler. That will.

The structure and the embodiment will be described in detail with reference to the drawings.

First, in the structure, the water supply pipe 22 is connected to the upper one side of the (-) ion resin tank 14 and the other end of the transport pipe 20 connected to the other lower part is connected to the upper end of the (-) ion resin tank 15 (- The other end of the transfer pipe 20 connected to the other side lower end of the ion resin tank 15 is connected to the upper portion of one side of the activated carbon 16, and the lower end of the activated carbon 16 via the transfer pipe 20 through the middle water tank ( 17 is connected to a lower portion of the middle stream tank 17 and a plunger pump 17 'is connected to a lower portion of the midstream water tank 17 with a transfer pipe 20 interposed therebetween. The middle water tank 17 'and the lower part of the plunger pump 17 is provided with a buffer tank 18 with a transfer pipe 20 interposed therebetween and connected to the other side of the buffer tank 18. The distal end of the feed pipe 20 is connected to the distribution pipe 3 'installed below the burner boiler 1 in a cylindrical shape with the automatic adjusting device 21 interposed therebetween. The dividing pipe 3 'is connected to one end of the plurality of steam generating pipes 3 with small holes 3 ", and the other ends of the steam generating pipes communicate with each other. A plurality of saturated steam generating pipes 5 having a plurality of small pipes 4 interposed therebetween at a side end are connected in a "d" phase, and a plurality of small pipes 4 'are provided at the other end of these saturated steam generating pipes 5. The high-temperature dry saturation steam generating tube (7) is connected to a plurality of dry saturation steam generating tube (6) "d" and the other end of the dry saturation steam generating tube (6) through a plurality of small tubes (4 "). The other end of the high heat saturation steam generating pipe (7) is connected to the steam injection chamber (9) of the spray nozzle (8) placed on the support (8 ") via the outlet pipe (7), and the spray nozzle ( 8) One side of the waste oil injection chamber 10 in the connector 8 'screwed to the rear side of the waste oil tank 10' and the oil supply pipe 10 "are connected, and the other side of the waste oil injection chamber 10 is the injection pipe ( 11) and Although the above-mentioned high-temperature steam injection chamber 9 which interposes the heat shielding plate 12 through the heat dissipation board 12 is communicated to the front-end | tip part of the injection pipe 11, and the heating crater (') of the burner boiler 1 in front of the injection pipe 11. Is located on one side of the main surface of the heating crater (1 ') is provided with an external air inlet (23) and a preheating chamber (2) is installed on the bottom of the burner boiler, but the combustion wick (2') on the bottom of the burner boiler In the circumferential wall, a plurality of vent holes (2 ") are drilled, and the heating crater (13 ') of the industrial boiler (13) is folded in front of the burner boiler (1).

The apparatus of the present invention configured as described above is to completely burn the non-recyclable waste oil such as bunker C oil or mobil oil to obtain a new pollution-free energy and to be a burner for heating the industrial boiler in use. The explanation is as follows.

When water is supplied to the positive ion resin tank 14 through the water supply pipe 22, the water is purified in the negative ion resin tank 15 and the activated carbon tank 16 through the transfer pipe 20 to be pure distilled water. It is sent to the distillation tank 17.

The water in the distilled water tank 17 thus obtained is buffered and adjusted in the buffer tank 18 through the plunger pump 17 'and then transferred to the distribution pipe 3' installed in the burner boiler 1. The water transferred to the pipe 3 'is introduced into the steam generating pipe 3 through the small holes 3 "through which the plurality of steam generating pipes 3 connected to the distribution pipe 3'.

At this time, since the water to be conveyed is pumped by the plunger pump 17 ', the amount of water is evenly distributed since the water is introduced through the small holes 3 "of the steam generating pipe 3 with considerable pressure.

When the preheating chamber (2) installed on the bottom of the burner boiler (1) is ignited in such a state, the flames ignited here are a plurality of steam generating tubes (3) and saturated steam generating tubes disposed on the inner circumferential wall of the burner boiler (1). (5), the dry saturation steam generating tube (6) and the high temperature steam generating tube (7) are heated simultaneously.

In the heating process as described above, the steam heated in the steam generating tube (3) is saturated and diffused in the narrow hole of the small tube (4) when it is introduced into the saturated steam generating tube (5) through the multiple small tube (4) Saturated steam that has become steam and heated in the saturated steam generating pipe (5) is rapidly diffused from the narrow hole of the small pipe (4 ') when flowing into the dry saturation steam generating pipe through a plurality of small pipe (4') Saturated steam and dried saturated steam heated in the saturation steam generating tube (6) is diffused in a small hole as it enters the high heat saturation steam generating tube (7) through a number of small tubes (4 ") After being in the vapor state, it is introduced into the steam injection chamber 9 of the injection nozzle 8 through the discharge pipe 7 '.

The vapor pressure at this time is 25-35KG / CM3 and the temperature is in the range of 600-700 degrees Celsius.

At this time, when the waste oil in the waste oil tank 10 'is introduced into the spray pipe 11 through the waste oil injection chamber 10 formed in the connector 8' connected to the spray nozzle 8 through the oil feed pipe 10 ", In front of the injection pipe 11, the steam injection chamber 9 through the heat shield plate 12 communicates with and injects the high pressure high temperature steam from the steam injection chamber 9. The process of mixing with the thermal steam of the heat shielding plate 12 prevents the carbonization of the waste oil and is ignited and burned by high heat. At this time, the waste oil that is burned by the ignition becomes minute particles due to heat steam at high pressure and high temperature. When it is injected to the injection pipe 11 in the completely burned state close to 100% and is introduced into the heating crater 1 'of the burner boiler 1, since the oxygen is supplied from the external air inlet 23, its combustion state Is a gasified phase rather than a liquid atomization. It burns in the womb, so no dust or soot is produced.

When the burner boiler 1 is heated in this way, at this time, the combustion of the preheating chamber 2 is interrupted and the steam generating pipe 3 installed in the burner boiler 1 as the heat of combustion of the waste oil injected from the injection pipe 11 is used. ), Saturated steam generating tube (5), dry saturation steam generating tube (6) and high temperature dry saturation steam generating tube (7) are heated in a row and their flames are installed in the front of burner boiler (13) It is introduced into the heating crater (13 ') of the industrial boiler (13) to warm up.

The heating adjustment and the transfer adjustment of the distilled water as described above are automatically operated in accordance with the set instruction of the automatic adjustment installation unit 2 provided on the rear side of the burner boiler 1.

As a result of the above, there were the following advantages.

1. The water flowing into the steam generating tube (3) passes through the (+) (-) ion resin tank (14) and (15) activated carbon (16), and the various minerals contained in the water are completely removed. 3), of course, no scale was generated in the inner wall of the saturated steam generating tube (5), the dry saturation steam generating tube (6), and the high-temperature dry saturation steam generating tube (7), thereby significantly extending the life of the tube.

In other words, the use of ordinary tap water without passing through the positive (+) (-) ion resin tanks (14) and the activated carbon tank (16) prevented the generation of high-heat-saturated vapors due to the scale being caught on the inner wall of the tube within 10 days.

2. The waste oil burned in the injection pipe 11 is mixed with high-pressure steam of 25-35KG / CM3 and high temperature steam of 550 ° C or higher to become ultrafine particles. Therefore, the ultrafine particles are completely oxidized when folded with air (oxygen). There is no dust or soot generated by incomplete combustion (oxidation) and it is close to 100% complete combustion.

That is, the performance was superior to the conventional fuel pressurized injection nozzles and rotary injection rotary burners or steam and air injection nozzles.

3. In the present invention, since only the (+) (-) ion resin tank 14, 15, activated carbon 16, distilled water tank 17, burner boiler 1 and waste oil tank 10 'are installed, Since the installation area is simple and the installation area is also small, compared with the conventional cyclone, multi-cyclone, bag filter, electrostatic precipitator, cleaning dust collector, etc., there is an economical advantage that cannot be compared in terms of installation area and installation mechanism.

4. In terms of maintenance and durability, various dust collectors in the related art have a general downtime in case of partial failure due to the complexity of the mechanism, but the present invention has no failure because of the simple mechanism, and quickly grasps a fixed part in case of failure. As a result, the utilization rate could be maximized.

5. In the working environment, the present invention has no dust or smoke at all, so the working environment is clean, and thus the worker's work efficiency is so good that it is incomparable with various conventional dust collectors.

However, when the waste oil was vaporized and burned in the injection pipe 11, some low binge occurred, but the noise was satisfactorily prevented by the noise plate attached to the burner boiler (1).

As described above, the present invention not only recycles low-quality non-recyclable waste oil which is a social pollution factor as a new energy source, but also enables the complete combustion thereof, thereby maximizing thermal efficiency and preventing soot or dust, which is a factor of industrial pollution, almost completely. It can greatly contribute to energy saving and prevention of industrial pollution.
