Landfill recovery device for dead body using Brown Gas {METHOD FOR SOIL REMEDIATION USING BROWN GAS}

The present invention relates to a device for restoring a landfill body using brown gas, and more particularly, to restore a burial site of a livestock infected with a livestock epidemic such as foot-and-mouth disease and to incinerate dead bodies and contaminated soil in a burial ground to remove pathogens and recycle them. The present invention relates to a landfill soil restoration apparatus using brown gas capable of producing aggregate.

Foot-and-mouth disease (FMD) is the malignant epidemic among the OIE List A Diseases of cattle designated by the International Water Services Bureau (OIE). It is found in cloven-hoofed animals, such as pigs, sheep deer, and elephants, with a sharp rise in body temperature, blisters (vesicles) in the mouth, hoof nipples, and loss of appetite, causing severe illness or death. It is characterized by being.

In order to prevent the spread of foot-and-mouth disease, we are actively carrying out quarantine activities without distinguishing between vehicles and livestock farms.

Despite these prevention activities, livestock infected with foot-and-mouth disease are produced, and carcasses of killed or killed livestock during the outbreak of livestock epidemics such as foot-and-mouth disease and bird flu have largely depended on the method of investment.

In recent years, as foot-and-mouth disease occurs, more and more landfills are disposed of by killing livestock and poultry infected with pathogens.

The process of killing livestock and poultry caused by pathogenic viruses such as foot-and-mouth disease and bird flu is carried out according to the government's environmental management guidelines for burial of livestock. Install permeable liner.

Thereafter, the killing process is to install a leachate drainage pipe at the bottom of the inclined bottom surface, and put 1m of soil from the draft in the bottom of the pit.

In this case, 5 cm of quicklime is put in the middle part of the soil to be put into the bottom, and the body to be buried is introduced at a height of 2 m, and then a gas discharge pipe is properly installed on the top of the body. Then, about 0.4m of soil is put on the carcass, and the quicklime is laid at a thickness of 5cm.

However, in the above-described landfill method, it is difficult to secure perfect ordering performance because vinyl orderer is easily damaged in the process of connecting gaps of orderer such as vinyl at the bottom and side of the investment pit or the process of investing livestock. to be.

In this case, the leachate generated during the decay of the livestock, which flows through the damaged vinyl, pollutes the soil and groundwater around the buried land or flows into the surrounding stream, causing secondary environmental pollution.

Residents around such burial sites continue to raise environmental pollution issues such as leachate spillage, groundwater contamination and odors.

This environmental pollution problem can occur at any time for years until the body's decay is completely settled and stabilized, so the authorities are currently putting in a lot of personnel to follow up to prevent environmental pollution problems.

In order to solve such a problem, a buried barrel is proposed, but the cost of purchasing a buried barrel is required, and the buried barrel may also leak contaminated water due to breakage and the like, and there is a problem of requiring separate management.

As shown in Figure 1, the carcass landfill restoration device using the brown gas according to the present invention, the brown gas tank for storing the brown gas generated in the electrolysis tank 10, the electrolysis tank 10 to make the brown gas (20), the gas supply means for supplying the brown gas stored in the brown gas tank 20 (30), refers to everything in the area where the livestock was buried in the molten water (dead body, contaminated soil, bones, etc.) ) Is injected into the molten incinerator 40 for melting and incineration the melted product by using brown gas supplied through the gas supply means 30, and recycling or treating the liquid melt as a by-product of melt incineration in the molten incinerator 40. It is composed of a cooling tank 50 to change the phase to a solid to be possible, it is possible to move as well as fixed. In other words, the mobile component is mounted on a trailer and moved, and the soil of the buried land where the livestock caused by infectious diseases such as foot-and-mouth disease are buried may not be transported to other lands due to the transmission of the infectious disease, so that the mobile is moved to the burial land. There is this.

The electrolysis tank 10 may use any electrolysis tank commonly used, and a method using groundwater around a buried land may be preferable. In the case of groundwater, the electrical conductivity may be low, and in order to solve this problem, the electrolysis tank may include an electrolyte tank for storing an electrolyte that increases the electrical conductivity of groundwater, and transfers the electrolyte stored in the electrolyte tank to the groundwater supply unit. It is divided into an electrolyte supply pipe for supplying, an electrolyte supply consisting of a valve for opening and closing the electrolyte supply pipe, an anode portion and a cathode portion and is installed in the electrolysis tank receiving ground water from the ground water supply portion, the anode portion and the cathode portion of the electrolysis tank, respectively The surface roughness is 0.1 to 0.5 micrometers, and is composed of first and second electrodes of different polarities which are electrolyzed by groundwater under power.

The brown gas tank 20 receives brown gas generated from the electrolysis tank 10 (gas transfer pipe, etc.) and stores the brown gas. The brown gas tank 20 is known to generate brown gas during electrolysis. Omit the description.

Brown gas is a gas obtained by electrolysis of water and is a mixed gas of exactly 2: 1 content ratio of hydrogen and oxygen. Normally, when water is electrolyzed, hydrogen is obtained at the cathode and oxygen is obtained at the anode. Brown gas is collected at once without collecting these gases separately.

Brown gas, unlike ordinary gas, has a unique property that causes an impingement phenomenon on combustion. In other words, it does not show an explosion phenomenon during combustion, but rather a flame gathers inside to form a focal point and vacuum the surroundings. As a result, when the brown gas is burned, it is possible to obtain ultra-high temperature enough to sublimate tungsten (melting point: 3,410 ° C, boiling point: 5,660 ° C), which has the highest melting point. In addition, the heating wire is released to the outside

Since there is no energy loss due to radiant heat, it has excellent energy efficiency and contains oxygen in itself, so no separate oxygen supply is needed during combustion. In addition, since only water (H 2 O) is produced as a combustion product, there is no pollution pollution problem.

The gas supply means 30 includes a gas pump 31 for pumping brown gas stored in the brown gas tank 20, a gas supply pipe 32 for supplying brown gas pumped by the gas pump 31, and a gas supply pipe 32. It consists of one or more Brown gas injection nozzles 34 for spraying Brown gas backflow preventer 33, the brown gas supplied through the gas supply pipe 32 in the melting incinerator (40) flowing along the.

The gas supply means 30 having such a configuration is made of a refractory material that is not deformed by high temperature because it transfers high temperature brown gas.

In particular, since the Brown gas injection nozzle 34 is inserted into the melting incinerator 40 and is in direct contact with the high temperature heat (about 1500 ° C to 2000 ° C) inside the melting incinerator 40, deformation and damage due to high temperature The cooling means 35 (refer FIG. 3) is provided so that it may not be. The cooling means 35 circulates a cooling medium (cooling water, cooling air, etc.) to the circumference of the brown gas injection nozzle 34 to protect the brown gas injection nozzle 34, and the circumference of the brown gas injection nozzle 34 The passage forms a flow path through which the cooling medium flows.

Melting incinerator 40 is to provide a space in which the melted material is incinerated, discharge for the discharge of the hopper 41 for the injection of the molten material, the melt (melting liquid only when melt incineration of the melt using brown gas) Part 42 is provided.

The discharge part 42 may be configured to forcibly discharge the molten liquid, or may be configured in an overflow (overflow) manner using the water level. The discharge part 42 is formed at a position higher than the bottom of the melting incinerator 40 for the overflow method. Of course, the discharge portion 42 is not limited to the overflow method, but a forced valve method is also possible.

The melted material may be sized by cutting to increase the efficiency of melt incineration, and the cutter for this may be all known, and the cut granularity may depend on the incineration capacity of the melt incinerator 40 or the brown gas supply amount. It is not limited to the specific number because it may vary.

In the case of the overflow method, it is preferable that a sorting network is mounted to prevent particulate matter from being discharged through the discharge passage 42.

Burners and the like necessary for melt incineration of the molten melt using Brown gas are well known and thus detailed drawings and descriptions thereof are omitted.

Of course, the melting incinerator 40 is composed of a refractory material that is not damaged by melt incineration.

The cooling tank 50 is a phase change of the melt generated due to melt incineration into a solid for the treatment such as recycling, solids such as pellets or agglomeration of the melt liquid discharged from the molten incinerator 40 by a quenching method by the cooling water Phase change to state. The cooling water may be used after being cooled to a predetermined temperature through a cooler or the like, or room temperature water that has not undergone a separate cooling treatment may be used, and may be circulated while being maintained at a predetermined temperature to increase cooling efficiency.

The melting incinerator 40 and the cooling tank 50 are connected to the transfer pipe 43, and the transfer pipe 43 transfers the melt liquid discharged from the melt incinerator 40 to the cooling tank 50.

At this time, before the melt is stored in the cooling tank 50, the phase change to a solid and the transfer pipe 43 will be blocked, in order to prevent this heater 60 for forming the inside of the transfer pipe 43 in a liquid atmosphere Is applied.

The heater 60 may include a heating jacket that generates electricity by receiving electricity and a method in which the heating medium circulates. In the present invention, a separate heater (heating temperature of about 100 ° C. to about) is used by using brown gas stored in the brown gas tank 20. 1000 ° C.) Reduces the cost of driving (temperature control may be achieved for use as a heating medium with brown gas).

The gas purifier 70 is connected to the inside of the melting incinerator 40 through a pipe line and includes an inhaler for sucking gas in the melting incinerator 40 and a water tank for purifying the gas sucked through the inhaler.

The gas purifier is a device for releasing the gas generated while melting the melted melt in the melting incinerator 40 through the purification process and supplying the gas generated in the melting incinerator 40 into the water tank to generate air bubbles. Soluble harmful gases and fine dust in the interior are dissolved in water, and the gas is released in a simple manner.

An inlet pipe for filling an appropriate amount of water into the tank and supplying the gas sucked through the inhaler into the water filled in the tank allows the outlet to be immersed in the water, so that the gas generated in the melting incinerator 40 It is supplied into the water inside the tank through the bubble is forced to generate harmful gases and fine dust in the air is dissolved by the water is purified by clear air is discharged to the gas discharge.

The carcass landfill restoration method using Brown gas according to the present invention is as follows.

The landfill soil (contaminated soil, carcasses, bones, etc.) of the buried land, which buried livestock infected with infectious diseases such as foot-and-mouth disease, was scooped out with a fork-lane, etc. It is operated to generate a brown gas and then stored in the brown gas tank (20).

The molten material is introduced into the melt incinerator 40 and the flame is generated through the burner while injecting the brown gas stored in the brown gas tank 20 through the gas supply means 30 to the melt incinerator 40 to generate the flame through the burner. The melted incinerator is melted and incinerated at about 2500 ° C to 3000 ° C. Therefore, the molten liquid is generated in the melting incinerator 40, and the molten liquid flows through the discharge part 42 into the transfer pipe 43.

At this time, since the inside of the transfer pipe 43 is formed in an atmosphere in which the molten liquid can maintain the liquid phase by the high temperature brown gas circulating in the heater 60, the molten liquid that flows from the melting incinerator 40 is cooled in the liquid state tank ( 50) and quenched.
