In general, as the people's standard of living improves, the use of disposable plastics increases and the amount of netting produced increases as the consumption of fish increases. In the case of waste materials such as the above disposable plastics, when buried in the ground It causes serious soil pollution, and waste materials such as the nets are dumped in the sea and are not properly collected, polluting the marine ecosystem to a serious level, causing desertification of the sea, discovery of deformed fish, and damage to the marine ecosystem. It ended up causing confusion.

Various technologies are being developed to reduce the disruption of the ecosystem and increase recycling efficiency. One of these is a technology that improves energy recycling by thermal decomposition of waste plastics.

Patented technologies related to the technology for pyrolyzing such waste include Registered Patent No. 1522997, a device for producing renewable fuel oil from waste materials through low-temperature pyrolysis, and Registered Patent No. 2029047, a low-temperature pyrolysis oil production device with a wax reprocessing device, and the main technology. There is a purifier for pyrolysis, which is Registered Patent No. 1869333 provided by the applicant.

Looking at conventional technologies, in order to recover the oil (wax) contained in the gas (emission gas, oil vapor) generated during thermal decomposition, the gas is cooled using water to recover the oil (wax).

That is, in general, foreign substances contained in the gas are removed using a purifier for pyrolysis using water (water bath), and the gas from which foreign substances are removed is supplied to the condenser for pyrolysis to collect oil (wax) contained in the gas. , the collected oil is supplied to an oil-water separator to separate the oil and moisture, and the gas is guided to a gas scrubber to remove dust and harmful gases and then discharged to the outside.

These pyrolyzer condensers collect oil in the gas by cooling the gas using water, and to increase the oil collection efficiency, multiple pyrolyzer condensers are connected in parallel.

In this way, when multiple condensers for pyrolysis are installed in parallel, a number of horizontal gas guide pipes are installed in the horizontal direction to guide gas between the condensers for pyrolysis. When used for a long time, the horizontal gas guide pipes are blocked by oil. Clogging occurs, causing various problems such as having to clean the clogged pipe at regular intervals and making it difficult to clean due to oil content.
