That is, the conversion efficiency of the waste liquid into the vapor state can be increased.

Further, a rotating blade 64 for raising air may be formed between the rotating shaft 61 and the blade 62. That is, by rotating the rotary vane 64 together with the blade 62, the air in the inner space can be further raised, so that a large amount of waste liquid can be easily converted into the vapor state.

The waste liquid evaporation apparatus 40 further includes a drain tank 47 for collecting waste liquid discharged through the drain 46. Therefore, the waste liquid injected from the gas evaporation concentrator 41 is converted into steam and is not converted yet, and is gathered to the lower part, discharged through the drain 46, collected in the drain tank 47, 47 may be supplied to the waste incinerator 10 and may be incinerated or re-supplied to the waste liquid evaporator 40.

When the first combustion gas supply pipe 31 is opened by the first opening and closing member 32 in the state where the waste liquid is completely burned, the combustion gas is supplied to the gas purifying member 30 and purified, have. If the opening degree of the first opening and closing member 32 and the second opening and closing member 43 is set to be different according to the circulation cycle of the combustion gas, a part of the gas is supplied to the gas purifying member 30, 40). In addition, when the combustion gas is circulated for complete incineration, it is possible to prevent incomplete combustion of the combustion gas by adjusting the spray amount of the waste liquid to a small amount.

Hereinafter, the operation and effects according to the embodiment of the present invention will be described.

First, the waste is incinerated in the waste incinerator (10). At this time, when the waste incinerator 10 is composed of the main incinerator 11 and the auxiliary incinerator 12, the main waste incinerator 11 is heated to a temperature of about 800 to 1,200 ° C. and the auxiliary incinerator 12 Lt; RTI ID = 0.0 > 850 C. < / RTI >

The combustion gas at about 800 to 1,200 ° C generated by the incineration of the waste in the waste incinerator 10 is supplied to the heat exchange boiler 20 and exchanges heat with the water to lower the temperature to about 200 to 400 ° C. Water or steam that absorbs heat from the combustion gas of the heat exchange boiler 20 is used for heating or power generation.

The combustion gas discharged from the auxiliary incinerator 12 or the heat exchange boiler 20 is supplied to the inside of the gas evaporator 41 of the waste liquid evaporator 40 through the second combustion gas supply pipe 42, The waste liquid is injected into the gas evaporator (41) through the waste liquid injection nozzle (44) and heated by the combustion gas to be converted into the vapor state.

The waste liquid and the combustion gas converted into the vapor state in the gas evaporation concentrator 41 are supplied to the waste incinerator 10 along the steam supply pipe 45 to be incinerated. As a result, the waste liquid in the liquid state is converted into high-temperature steam and burned, so that it can be easily burned.

Meanwhile, in order to completely incinerate the waste liquid in a vapor state, the waste liquid is supplied to the waste liquid evaporator 40 through the second combustion gas supply pipe 42 as a combustion gas, and then re-supplied to the waste incinerator 10. At this time, when the combustion gas of the waste incinerator 10 is circulated in the primary, secondary, tertiary, or the like, the amount of the waste liquid sprayed to the gas evaporation concentrator 41 may be reduced. Accordingly, the waste liquid contained in the combustion gas is completely burned, so that the smell and the like due to the incomplete combustion of the waste liquid can be completely removed.

When the waste liquid contained in the combustion gas is completely incinerated, the first open / close member 32 is operated to open the first combustion gas supply pipe 31, so that the combustion gas having been completely burned is cleaned through the gas purifying member 30 Filtered and discharged to the atmosphere.

As described above, since the waste incinerator 10 can change the waste liquid to the steam state by using the combustion gas generated by incineration of the waste, the waste incinerator 10 can be incinerated together with the waste incinerator 10, thereby saving energy resources.

In addition, the waste liquid can be easily converted into the vapor state by the combustion gas at 200 to 400 ° C, and the incineration ability of the waste liquid in the vapor state can be improved by the combustion gas at 800 to 1,200 ° C.

As described above, since the waste liquid is incinerated by the present invention, the waste gas and odors are also removed, which is a very useful invention that can be widely applied to an apparatus for incinerating waste liquid.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is to be understood, therefore, that the embodiments described above are to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, All changes or modifications that come within the scope of the equivalent concept are to be construed as being included within the scope of the present invention.
