The present invention relates to a pyrolysis device configured to pyrolyze waste to obtain regenerated fuel, and more particularly, to recover foreign substances and oils including dust at a difference in specific gravity in exhaust gas discharged from pyrolysis of waste, and to clean the exhaust gas. It relates to a purifier for a pyrolysis device configured to discharge to the atmosphere.

As society shows full-scale industrialization, as the waste caused by 'mass production and mass consumption' is rapidly increasing, the environmental pollution accompanying the waste disposal is seriously required. Therefore, efficient waste disposal plans are urgently required.

Generally, there are 'reduction', 'recycling', 'recycling', 'landing' and 'incineration' in the waste treatment method. Recently, various methods of pyrolysis of waste in high temperature and vacuum environment have been introduced, and patents have been introduced. Various pyrolysis apparatuses and methods are presented, developed and used as in the literature, and technologies are continuously being developed to provide more and more advanced technologies (reference patent document (KR) No. 10-0266852, (KR) registration Patent Publication No. 10-0513932, (KR) Patent Publication No. 10-0748624).

In general, an indirect heating pyrolysis apparatus for pyrolysis waste in a high temperature and vacuum environment includes a pyrolysis furnace including a pyrolysis furnace for pyrolyzing waste installed at an inside of a heating furnace, which is a heating means, at a high temperature and a vacuum state. And a refiner (oil collecting device) for collecting oil in the exhaust gas of the discharged waste.

The ordinary purifier 2 comprises a purifier tank 2a in which water is stored for cooling, and an exhaust gas guide tube 2b installed in the tank in a zigzag manner to guide the exhaust gas.

In the exhaust gas guide pipe 2b, as the time passes, foreign matters in the exhaust gas are loaded, and the inside of the pipe is clogged. In order to solve such a clogging phenomenon, a 'U' shaped connector (2c) for cleaning is installed in the bending section of the exhaust gas guide pipe (2b) installed in a zigzag shape, and the inside of the pipe is periodically cleaned.

As described above, when the connector 2c installed on the exhaust gas guide pipe 2b is separated and cleaned, there are various problems.

First, the efficiency is reduced due to the shutdown of the pyrolysis due to the cleaning.

Secondly, when the connector 2c installed on the exhaust gas guide pipe 2b is separated, odors are generated, and the worker's work avoidance and complaints are caused by the odors.

Third, the oil (Oil) contained in the exhaust gas is mixed with the foreign matter loaded in the tube has a disadvantage in that the recovery rate of the oil falls.

One or more tank diaphragms are installed in the lower side of the refiner body to separate the tank into a plurality of unit tanks, and the upper end of the tank diaphragm is located at a position higher than the lower end of the movable diaphragm.

The pyrolytic purifier may further include a cooling water tank for cooling the purifier body using the cooling water.

A plurality of separation grooves in the vertical direction may be formed in the movable diaphragm.

As described above, the purifier for a pyrolyzer according to the present invention has a zigzag-type exhaust gas movement path formed in the exhaust gas passage part by a plurality of movement path diaphragms, so that the movement path of the exhaust gas becomes long, so that foreign substances in the exhaust gas are lowered. The foreign matter falls to the provided water tank unit, and the foreign matter dropped into the water tank unit is not mixed back into the exhaust gas, thereby reducing the amount of foreign matter contained in the exhaust gas discharged to the atmosphere.

In addition, the exhaust gas is cooled by the cooling water tank to increase the efficiency of separating the oil and foreign matter and water contained in the exhaust gas.

In addition, since a plurality of separation grooves in the vertical direction are formed in the moving plate diaphragm, the collection efficiency of oil and foreign matters is increased.
