Condenser for pyrolysis and A thermal decomposition treatment device with this}

The present invention relates to a condenser for a pyrolysis machine that can collect oil by cooling gas (oil vapor) that has passed through a purifier for collecting oil that separates impurities such as tar from gas (oil vapor) generated during the pyrolysis process of waste plastics, waste vinyl, waste synthetic resin, etc., and specifically, guides installed in a horizontal direction to guide gas (oil vapor) between a plurality of condensers provided to cool the gas (oil vapor) in multiple stages. It relates to a condenser for a thermal decomposition device not including a tube and a thermal decomposition treatment device having the same.

In general, as the standard of living of the people improves, the use of disposable plastics increases and the amount of fish consumed increases. Waste materials such as the disposable plastics cause serious soil contamination when buried in the ground, and waste materials such as the nets are dumped into the sea and are not properly collected, contaminating the marine ecosystem to a serious level, causing desertification of the sea, discovery of deformed fish, and confusion of the underwater ecosystem. reached

Various technologies are being developed to reduce the chaos of the ecosystem and increase recycling efficiency, and as one of them, a technology to improve energy recycling by pyrolysis of waste plastics is being developed.

Patented technologies related to the technology of pyrolysis of such waste include Patent No. 1522997, a device for producing recycled fuel oil from waste materials through low-temperature pyrolysis, Patent No. 2029047, a low-temperature pyrolysis oil production device having a wax reprocessing device, and Patent Registration No. 1869333 provided by the present applicant, such as a refiner for a pyrolysis machine.

Looking at conventional technologies, in order to recover oil (wax) contained in gas (exhaust gas, oil vapor) generated during pyrolysis, water is used to cool the gas to recover oil (wax).

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

The pyrolysis condenser uses water to cool the gas and collects oil in the gas. In order to increase the oil collection efficiency, a plurality of pyrolysis condensers are connected in parallel and used.

In this way, when a plurality of pyrolysis condensers are paralleled, a plurality of horizontal gas guide tubes are installed in the horizontal direction to guide gas between the condensers for pyrolysis, and when used for a long time, the tubes are clogged with oil in the horizontal gas guide tube. This causes various problems such as the need to clean the clogged tubes at regular intervals and the difficulty in cleaning due to oil components.

It may not include a horizontal pipe.

In addition, since it is made of a single pyrolysis condenser instead of a plurality of unit pyrolysis condensers, it is easy to install and manufacture, thereby creating an effect of lowering the product unit price and installation cost.

In addition, it is possible to create an effect that can drastically reduce the installation space by being composed of a single pyrolysis condenser instead of a plurality of condensers for pyrolysis units connected in parallel.

In addition, the piping line can be simplified by placing the oil-water separator and the gas scrubber below the condenser for the thermal decomposition of the present invention.

In addition, it is easy to install a cover (cover) or manhole for inspection and cleaning in the upper flue part and the lower flue part that guides the gas in the horizontal direction, so maintenance is easy.
