In general, as the standard of living of the people improves, the number of disposable plastics increases, and as the amount of consumed fish increases, the number of net meshes is continuously increasing. In the case of waste materials such as disposable waste plastics, It causes serious soil pollution, and the waste materials such as the net are dumped in the sea and are not properly collected, so that the sea ecosystem is seriously polluted and the desertification phenomenon of the sea, deformed fish discovery, and the underwater ecosystem It has led to confusion.

The pyrolysis furnace 110 burns fuel supplied from a fuel tank 101 by a pump 102 into a burner 111 to dissolve waste plastics, A gas separator 120 for extracting gas (vapor) generated in the pyrolysis furnace, a tar separator 130 for separating tar from the gas supplied from the gas separator, A wax separator 140 for separating the wax from the wax, a wax collecting condenser 150 for collecting the wax again from the remaining gaseous body after the wax is separated from the wax, a wax collecting condenser 150 for storing the wax collected from the wax collecting condenser, And a known pyrolysis oil processing device 200 connected to the wax collecting condenser to produce pyrolysis oil by a series of processes.

The pyrolysis oil processing unit 200 includes a plurality of condensers 210 for cooling the vapor and a pyrolysis unit 250 through the backfire prevention unit 220 and the collecting / decomposing tank 230, the oil filter 240 and the oil water separator 250, The oil is pyrolyzed during the process of cooling, refining, and mixing, and pyrolysis oil having intermediate characteristics of heavy oil and light oil is produced. The quality of the pyrolysis oil produced at this time is different depending on the quality, temperature and pressure of the raw material plastic.

Wax (including tar) is produced during the process of producing pyrolysis oil by using waste materials (e.g. waste plastic, waste net for fishing, industrial chemical polymer water, containers using naphtha which is a main product refined in crude oil, etc.) The wax is sensitive to heat and has a hardness to harden, so that a caulking phenomenon, a nozzle and a pipe clogging phenomenon inevitably occur during passage through the pyrolysis oil treatment device 200.

Therefore, the conventional pyrolysis oil production plant has a disadvantage in that the productivity is remarkably deteriorated due to a delay in operation due to wax and a cost burden due to repair or the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a low-temperature pyrolysis oil producing apparatus having a wax reprocessing apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

Fig. 2 is a structural view of the wax reprocessing apparatus in the present invention, and Fig. 3 is a process diagram of the pyrolytic oil production apparatus of the present invention.

First, in the drawings, it is noted that the same components or parts are denoted by the same reference numerals as possible. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted so as to avoid obscuring the subject matter of the present invention.

The low temperature cracked oil producing apparatus provided with the wax reprocessing apparatus according to the embodiment of the present invention is characterized in that the fuel supplied from the fuel tank 101 by the pump 102 is burned by the burner 111 to melt the waste plastics, A gas separator 120 for extracting gas generated from the pyrolysis furnace 110 and a tar separator 120 for separating tar from the gas supplied from the gas separator 120, A wax separator 140 for separating the wax from the residual gas by separating tar from the wax, a wax collecting condenser 150 for collecting the wax again from the remaining gas after the wax is separated, A wax storage tank 160 for storing the wax collected from the wax collecting condenser 150 and a well-known wax storage tank 160 connected to the wax collecting condenser 150 for producing pyrolysis oil by a series of processes A pyrolysis oil treatment device 200, It made of a material processing apparatus.

The wax reprocessing apparatus includes a wax supply pipe 162 having one end connected to the wax storage tank 160 and having a pump 161 and the other end connected to the wax supply pipe 162 to supply the wax to the pyrolysis furnace 110 A pump 171 for pumping the wax supplied to the wax constant amount feeding device 170 in a predetermined amount and a pump 171 connected to the pump 171 to supply the wax to the pyrolysis furnace 110 And a wax injection pipe 172 for injecting wax into the gas decomposition furnace 110. The wax injection pipe 172 is disposed inside the pyrolysis furnace 110 through the gas separator 120. [

At this time, the wax separator 140 and the wax collecting condenser 150 have the same function, so that it is natural that any one of them can be selectively used.

The wax connecting pipe 142 of the wax collecting cylinder 141 and the tar connecting pipe 132 of the tar collecting cylinder 131 are connected to the wax supplying pipe 162. When the wax is pumped by the pump 161, The wax and tar collected in the collecting cylinder 131 and the wax collecting cylinder 141 may be simultaneously pumped and supplied to the wax quantity feeder 170. [

At this time, the tar collecting tank 131 is located at the lower end of the tar separator 130, and the tar separator 130 is a device for separating tar from the vapor. The tar is in a state of being submerged in the inner hot-water pipe of the tar separator 130. The hot-dip pipe has a double-tank type hot-water type warming device for preventing the tar from hardening.

The wax collector 141 is located at the lower end of the wax separator 140. The wax separator 140 is a device for separating the wax from the vapor. Also, the wax is in a state of being immersed in the internal hot water tank of the wax separator 140, and the hot water tank is provided with a double-tank type hot water type warming apparatus to prevent the wax from hardening.

That is, the vapor generated in the pyrolysis furnace 110 passes through the gas separator 120 and the gas transfer pipe 121 through the wax separator 140. During this process, the vapor is decomposed by the bubble in the hot water pipe . That is, since the bubble has a large volume of the gas, when the wax contained in the gas is large, the bubble is finely decomposed by the decomposition network installed in the wax separator 140, and the first wax is separated in this process. At this time, the separated wax is deposited and stored in the wax collection cylinder 141 due to the difference in specific gravity. The separation of the tar is also the same as that of the wax.

The vapor may be returned to the wax collecting condenser 150 for separation. At this time, the wax is separated through a plurality of cooling tubes installed inside the wax collecting condenser 150. That is, the wax having a heavy specific gravity out of the vapor passing through the cooling pipe is settled, and the pure water vapor is discharged and supplied to the pyrolysis oil treatment device 200.

At this time, when the internal temperature of the wax collecting condenser 150 is 250 ° C or higher, the wax is vaporized as well. Therefore, it is preferable to provide a cooling means on the outside of the wax collecting condenser 150 to prevent a temperature rise.

The separated wax is stored in the wax storage tank 160 and then supplied to the wax quantity supply device 170. At this time, the wax quantity supply device 170 operates the helical pump by an inverter starting method to pyrolyze a certain amount of wax (110). At this time, it is preferable that the amount of wax stored in the amount-of-wax-supplying device 170 is checked by a wax storage amount checking device so that a certain amount of wax can be always stored at a constant rate and at a constant rate.

As described above, since the wax separated once is sent back to the pyrolysis furnace 110 to be reprocessed, it is supplied to the pyrolysis oil processing furnace 200 in a fully decomposed state, thereby solving the phenomenon of caulking, nozzle and pipe clogging .

Although the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the present invention is not limited thereto and that various changes and modifications will be apparent to those skilled in the art. Various modifications and variations are possible within the scope of the appended claims.
