However, the pyrolysis apparatus has a problem in that the combustion heat introduced into the regeneration chamber is discharged only in one direction, so that the efficiency of combustion heat associated with pyrolysis of the regeneration furnace is greatly reduced.

The thermal efficiency is greatly reduced because the thermal decomposition of the.

In addition, since the pyrolysis device having such a configuration is limited to simply pyrolyzing the waste inside the regeneration furnace as a high temperature combustion heat introduced into the regeneration chamber, its utilization is extremely low. In other words, although the heat of combustion introduced into the combustion chamber is still maintained at a high temperature even after heating the regeneration furnace to pyrolyze the waste therein, such high combustion heat is conventionally used only for pyrolysis and then through the exhaust pipe. As it is discharged as it is, it is a big heat loss.

This is made up.

At this time, the input means is horizontally communicated from the upper outer surface of the regeneration furnace, the waste input pipe in the upper end of the hopper communication; It is installed at the rear end of the waste inlet pipe, and the waste supplied from the hopper is introduced into the regeneration furnace by the forward / reverse operation of the cylinder, and the outer surface of the waste inlet tube is in close contact with the inner surface of the waste inlet pipe to complete the A piston coupled with a seal to prevent leakage; And a switch installed between the waste inlet and the hopper to supply waste by opening the hopper in a state in which the piston is reversed, and the piston to block the hopper during the forward operation.

The present invention is characterized in that as shown in Figures 1 to 3 largely, the regeneration furnace 200 is formed on the combustion heat guide plate 210 and the input means for inputting the waste supplied from the hopper is installed on the top of the regeneration furnace And a hot water supply pipe 400 for supplying hot water as its combustion heat via the interior of the regeneration chamber.

First, the regeneration chamber 120 of the present invention supports the regeneration furnace 200 therein and at the same time between the double metal plates 122 to prevent the combustion heat circulated therein from being lost through contact with the outside air. Insulation material 124 is filled. That is, the metal plate 122 and the heat insulator 124 are heat-resistant reinforcement materials that are not deformed or damaged by high-temperature combustion heat. In particular, the rear side of the main body is 35 to 45 from the ground with the regeneration furnace 200 installed therein. It has an inclination of degrees, and the rear end of the inclined body extends to have an inclination of 60 to 70 degrees from the ground. Therefore, the regeneration chamber 120 formed as described above and having an inclination is formed to be movable on the ground by a separate frame frame, and a combustion chamber is connected to the front end thereof and a combustion heat exhaust pipe 126 is formed at the rear end thereof. This results in the supply and discharge of combustion heat.

The regeneration furnace 200 is to generate pyrolysis gas by pyrolyzing the waste introduced and installed in the regeneration chamber 120 by using high temperature indirect heat, and is formed at the same slope as the regeneration chamber 120 to form the slope. This results in smooth input and discharge of waste. On the other hand, since the present invention is applied to a pyrolysis device formed mainly in a small capacity rather than a large capacity, a configuration of a single condenser 140 is preferable. The inclined upper end of the regeneration furnace 200 has the pyrolysis gas generated therein as the condenser 140. Decomposed gas exhaust pipe 142 vertically communicated to guide is formed, a waste input means for injecting waste supplied from the hopper is formed on one side of the outer circumferential surface of the inclined upper end, pyrolysis at the front end of the regeneration furnace 200 Residue outlets 220 and switchgear 230 for discharging the residue of the waste is formed.

In particular, the outer surface of the regeneration furnace 200, the combustion heat guide plate continuously protruding in a spiral shape so that the high temperature combustion heat introduced from the combustion chamber 110 into the regeneration chamber 120 circulates while turning the outer surface of the regeneration furnace 200. 210 is integrally formed. In this case, the combustion heat induction plate 210 maintains a gap between the regeneration chamber 120 and the regeneration furnace 200 and forms a mutual support structure.

The injection means not only prevents the pyrolysis gas inside the regeneration furnace 200 from leaking by the forward and backward operations of the piston 300, but also introduces waste introduced from the hopper 130 into the regeneration furnace 200. It is formed to be injected. That is, the waste is stored in the upper end of the waste inlet pipe 310 in the state in which the waste inlet pipe 310 is horizontally communicated so that the piston 300 is operated forward and backward on the upper outer surface of the regeneration furnace 200. Hopper 130 is formed in communication.

At this time, while the piston 300 is moved forward and backward by the operation of the cylinder 320 installed at the rear end of the waste inlet pipe 310, the waste supplied from the hopper 130 is introduced into the regeneration furnace 200, Sealing 300A is coupled to the outer surface such that pyrolysis gas does not leak while being in close contact with the inner surface of the waste inlet tube 310. On the other hand, between the waste input pipe 310 and the hopper 130 is interlocked with the operation of the piston 300, the switch 330 for opening and closing that the waste inside the hopper 130 is introduced into the waste supply pipe 310 Is formed.

The hot water supply pipe 400 is for supplying the hot water as the heat of combustion via the interior of the regeneration chamber 120, one end of which is in a coiled form along the inner surface of the regeneration chamber 120. It is connected to the 410 and the other end is connected to the cooling water outlet of the condenser 140 is formed to form a single circulation structure. That is, one end of the hot water supply pipe 400 wound at the inlet of the regeneration chamber 120 is connected to a predetermined water tank 410, the water tank 410 is connected to the heating pipe 420, the heating pipe 420 is connected to a cooler 430 for cooling the water circulated to a predetermined temperature, the cooler 430 is connected to the cooling water inlet of the condenser 140, from the cooling water outlet of the condenser 150 It is formed in a single circulation structure connected to the other end of the hot water supply pipe 400 wound on the rear end of (120).

On the other hand, one side of the water tank 410 is further provided with a water tap 420A so that the stored hot water can be used directly as water.

According to the present invention having such a configuration, after generating combustion heat of about 850 to 1000 degrees from the combustion chamber 110, the heat is introduced into the regeneration chamber 120 to heat the regeneration furnace 200 as the heat. Will maintain a temperature of about 500 degrees Celsius.

At this time, the heat of combustion introduced into the regeneration chamber 120 is circulated while rotating spirally by the combustion heat induction plate 240 formed on the outer surface of the regeneration furnace 200, so that the thermal resolution of the regeneration furnace 200 is improved. That is, since the combustion heat introduced into the regeneration chamber 120 spirally rotates, the temperature distribution of the introduced combustion heat is the same as that of the upper and lower layers, so that the overall thermal decomposition is uniform, and the combustion heat is rotated around the outer surface of the regeneration furnace 200. Is discharged through the combustion heat exhaust pipe 122.                     

The pyrolysis gas generated inside the regeneration furnace 200 is guided to the condenser 140 through the cracked gas exhaust pipe 142 of the inclined upper end, and the pyrolysis gas guided to the condenser 140 is from the cooler 430. Pyrolyzed oil is extracted while being liquefied by the introduced cooling water. At this time, the waste supply pipe 310 is sealed by the seal 300A in the state where the piston 300 is advanced, thereby preventing the pyrolysis gas from leaking to the outside.

On the other hand, when the waste is supplied into the regeneration furnace 200, the piston is reversed by the operation of the cylinder 320 in a state in which the switch 330 between the waste supply pipe 310 and the hopper 130 is closed, In the state in which the piston 300 is completely backward, the switch 330 is opened to introduce a certain amount of waste. Subsequently, as the piston 300 is advanced by the operation of the cylinder 320 in the state where the predetermined amount of waste is completed and the switch 330 is closed, the waste introduced into the waste supply pipe 310 is introduced into the regeneration furnace 200. do.

In addition, as the operation for supplying the waste proceeds, the switch 230 installed at the outlet 220 in front of the regeneration furnace 200 is opened to discharge the residue of the pyrolyzed waste.

In addition, hot water for heating or water may be continuously supplied through the hot water supply pipe 400. That is, when the coolant discharged from the condenser 140 is circulated into the hot water supply pipe 400, the coolant is stored in the water tank 410 while being heated by the combustion heat in the regeneration chamber 120.

At this time, the hot water stored in the water tank 410 can be used as hot water for general water through the water tap 420A.

On the other hand, the hot water stored in the water tank 410 is circulated to the heating pipe 420 for heating of each home or office building. In this case, it is well known that smooth circulation is achieved through a compressor having a constant pressure, so a description of the configuration is omitted.

The hot water that has been heated in each building is introduced into the cooler 430 in a state of being lowered to a predetermined temperature, and the cooler 430 recools the introduced water to an appropriate temperature to supply the condenser 150. . Therefore, the water cooled through the cooler 430 is introduced into the condenser 150, so that the liquefaction of the pyrolysis gas circulated inside the condenser 150 becomes more efficient, and thus more pyrolysis oil can be extracted.

Finally, the cooling water condensing the pyrolysis gas is circulated back to the hot water supply pipe 400 to form a single circulation structure.

By not only smooth waste input, but also prevent the leakage of pyrolysis gas, and by continuously supplying hot water for heating or water using the heat of combustion in the regeneration chamber through the hot water supply pipe, a very economical and practical effect is exhibited.

In addition, by forming the combustion chamber with a double metal plate and a heat insulating material of the heat-resistant reinforcement material, not only the heat loss emitted to the outside is reduced, but also by unifying the condenser installed outside the combustion chamber, the pyrolysis apparatus is easily moved from the ground. It is very useful to install.

In addition, by circulating the water cooled to a certain temperature by the cooler into the condenser to utilize the cooling water, the condensation rate of the pyrolysis gas is further improved, and thus a very useful effect of extracting more pyrolysis oil is exerted.
