In addition, although not shown in detail in the drawings, the present invention is also applicable to a thermometer, a pressure gauge, a flow meter, and the like in an appropriate place for effective control and management of the device.

5 and 6, the ceramic electric band heater 38 may be provided outside the combustion body 32 in comparison with the above-described preferred embodiment, So as to cover the heat quantity at low cost.

At this time, the ceramic electric band heater 38 is arranged to be spaced apart in the longitudinal direction so as to surround the outside of the combustion body 32 in a U-shape, and fastening bolts are fastened and fixed to the upper portion.

7 and 8, in comparison with the above-described preferred embodiments, the combustion body 32 is provided with an incision groove 39a in which an upper center is longitudinally incised, A nozzle 33 is provided in the auxiliary inner cylinder to form a clearance t spaced apart from the combustion body so that the pure liquid material is heated by heating steam And when the liquefied gas is not discharged, the gas is discharged to the discharge port through the clearance between the combustion body and the auxiliary inner cylinder.

At this time, the combustion body 32 and the auxiliary inner cylinder 39 form a spacing gap by the gap holding tool 39b, and the auxiliary inner cylinder 39 is internally coated for the purpose of cleaning the inner scale and is replaceable do.

Reference numeral 33a denotes a supply pipe for supplying the liquid material; and 55, a receptacle for collecting the pure liquid material to be liquefied by the cooling means.

Hereinafter, the operation and operation of the present invention will be described.

First, the waste fluid from the blood of the livestock, food waste, livestock wastewater (drainage) and various industrial wastewater is collected and collected in the waste liquid storage tank 10.

And the waste liquid of the waste liquid storage tank 10 is subjected to no-discharge treatment.

More specifically, the waste liquid in the waste liquid storage tank 10 is supplied to the solid-liquid separator 20 and is compressed, thereby separating the solid matter and the liquid matter.

The separated liquid material is compressed again through the solid-liquid separator 20 to separate the solid material and the liquid material through a plurality of stages, and then the liquid material is collected into the liquid material storage tank 60.

The liquid material collected in the liquid material storage tank 60 is supplied by the pump 62 to the nozzle 33 provided in the incinerator 30 along the longitudinal direction of the combustion body 32, To the combustion chamber 32a inside the combustion body.

At this time, the flame is sprayed in the longitudinal direction of the combustion chamber 32a from the burner 35 installed at one side of the combustion body 32, and the liquid material finely injected into the combustion chamber is heated and incinerated.

That is, the liquid material is finely sprayed and heated by the burner to burn various kinds of foreign substances contained in the liquid material, thereby making the pure liquid material into a heated vapor state.

5 and 6, a ceramic electric band heater 38 is installed outside the combustion body 32 to heat the inside of the combustion body together with the burner, thereby covering a low heat amount from the burner at a low cost Various kinds of foreign substances contained in the liquid material are reliably incinerated and the efficiency of vaporizing the pure liquid material is further enhanced.

The heating steam generated by burning the pure liquid material in the combustion body 32 in this way is discharged to the outside through the exhaust port 36.

Particularly, the salt or the like generated in the incineration process of the liquid material is collected in the form of being fixed inside the conical cap 34 connected to one side of the combustion body will be.

In this process, the incinerator separates one side cap 34 of the combustion body 32 to clean the inside of the combustion body, as well as to continuously use the inside of the cap 34 while cleaning or replacing it.

As described above, the heating steam discharged to the exhaust port 36 of the incinerator is re-filtered through the filtration process for adsorbing foreign matter by the filter means 40 such as activated carbon, cooled by the cooling means 50, It is collected and recycled without discharge.

In this process, when internal pressure is generated in the exhaust port 36 in front of the filter means, the heated steam can not be discharged through the filter means, so that it is sensed by a pressure gauge or the like to drive the fan driving unit 45, So that the discharge of the heated steam can be smoothly performed.

In the meantime, according to the present invention, the pure liquid material is heated in the combustion body 32 of the incinerator and exhausted through the exhaust port 36 in a vapor state. When the pure liquid material is liquefied without being discharged to the exhaust port, 37, and is filtered by the filter means 40 to collect the pure liquid material.

7 and 8, an incision groove 39a is formed in the combustion body 32 so that the upper center is cut in the longitudinal direction, and the auxiliary inner cylinder 39, which is opened at both sides, is further inserted The pure liquid material is liquefied when the pure liquid material rises through the cutout groove 39a of the auxiliary inner cylinder by the heating steam and can not be discharged to the exhaust port so that the clearance t between the combustion body 32 and the auxiliary inner pipe 39 is increased, And is smoothly discharged.

In this case, the scale generated during the incineration process of the liquid material does not fall into the combustion body 32 but falls into the auxiliary inner cylinder 39 to be more easily cleaned. The auxiliary cylinder 39 ) Can be used only for replacement, it will be easy to replace.

9, the lower part of the outer housing 31 of the incinerator is mounted on the base and the hinge shaft 61, and the other part is mounted on the elevating / lowering means 60 such as a jockey. So that the front of the incinerator can be vertically inclined.

At this time, the liquid material injected through the nozzle of the incinerator is incinerated by the flame of the burner by adjusting the upward and downward inclination of the incinerator, so that it can be quickly discharged to the exhaust port 36 while maximally preventing stagnation in the incinerator So that the efficiency of the incinerator is further improved.

Therefore, the present invention separates solid waste and liquid waste from various waste liquids derived from the blood of the livestock, food waste, livestock wastewater (diurnal waste) and various industrial wastewater by the solid-liquid separator 20 and supplies the liquid waste to the incinerator 30 It is burned with the flame of the burner while spraying it through the nozzle, burning the foreign substances contained in the liquid material, discharging the liquid material in a vapor state, filtering and cooling it, collecting it, recycling the waste liquid,
