Recently, livestock farms are suffering a lot of damage due to livestock being killed due to infection with various diseases or infectious diseases. The damage caused by the dead livestock causes not only primary damage due to the death of the livestock but also secondary damage caused by processing the dead livestock containing pathogens, thereby causing livestock farmers to suffer a double whammy.

Conventionally, there is no treatment method other than burying the dead livestock in the ground because equipment for treating the dead livestock is not presented. As a result, even after burial of the dead livestock, pathogens contained in the dead livestock are transmitted to nearby livestock or people, or leachate generated from the dead livestock contaminates the groundwater, so that nearby farmhouses cannot use the groundwater.

In order to solve this problem, various dead livestock processing equipments are being developed. Recently, among waste livestock treatment equipment, the utility value of a hydrolysis treatment device that hydrolyzes dead livestock and animal residues is increasing, and recycling of dead livestock and animal residues liquefied by such a hydrolysis treatment device into compost etc. Research is ongoing.

This stirring device is composed of parts such as a driving motor, a stirring shaft, and stirring blades. In order to arrange these parts in the device, there is a problem of securing an additional space in the processing device, and due to this installation space, the processing device has a dead zone. (dead zone) There is also the problem of creating a space that is unnecessarily difficult to use.

In particular, in the case of treating the dead bodies of the burial site, not only the dead bodies but also the soil contaminated by the dead bodies are put into the treatment tank for hydrolysis treatment. . When the soil is precipitated in this way, it is not easy to evenly agitate and mix the soil with the existing agitating device, and there is a risk of failure or breakage by overloading the agitating device.

The heating unit 30 may be configured as a heating unit 31 in the form of a tube, a furnace, or a hot wire disposed under the treatment tank 20 to supply a heat source to the treatment tank 20 . In addition, the heating unit 30 may use any burner, boiler, electric heater, or the like that uses gas, oil, or electricity as a fuel for supplying a heat source. In this case, a temperature sensor for measuring the temperature of the hydrolyzate HL heated by the heating unit 30 may be installed in the treatment tank 20, and through this, the heating temperature and the temperature of the hydrolyzate HL It is also desirable to be able to monitor and control by the control panel.

In this way, the gas discharged while the hydrolyzate HL or the object to be treated is heated by the heating unit 30 is discharged to the outside through a separate discharge device, and the discharged gas is 280° C. or higher.

In general, when the hydrolyzate (HL) and the object to be treated are heated inside the treatment tank 20, the exhaust gas generated is discharged to the outside and discarded.

Therefore, in the present invention, it is intended to use the discarded high-temperature exhaust gas as an energy source for stirring.

That is, the exhaust gas generated when heating the hydrolyzate (HL) is not discharged through an exhaust device, but is directly recovered from the treatment tank 20 and used as an energy source for generating bubbles (B) for stirring.

Hereinafter, the waste heat recovery unit 40 and the bubble generator 50 for this will be described in detail with reference to the accompanying drawings.

Energy savings can be obtained. In addition, the treatment time can be shortened through the promotion of hydrolysis, and the sterilization effect can also be doubled by spraying high-temperature heat into the hydrolysis liquid (HL).

Unlike conventional agitation devices, there is no need to secure a separate space for waste heat recovery or the installation of the bubble generating unit 50, eliminating dead zones in the processing device, and through this, a compact device can be implemented.

In particular, when the object to be treated contains soil (E) to treat dead bodies buried in the soil (E), in the case of an existing agitation device, the agitation shaft or agitation wing is affected by the soil (E) precipitated inside the treatment tank (20) It is effective in that it can eliminate the problem of difficult stirring due to improper operation and the risk of damage to the stirring device.

That is, the bubbles (B) generated by spraying at high pressure can penetrate into the precipitated soil (E) to float the soil (E), and through this, the hydrolyzate (HL) and the soil (E) can be effectively stirred and mixed. Since it can be, it is possible to solve the above problems that may occur when introducing an existing stirring device.
