Description

Condenser for Pyrolysis Petrolizing Appratus

The present invention relates to a condenser used in a pyrolysis emulsification apparatus that produces pyrolysis oil by thermally decomposing and liquefying polymer waste such as waste plastics and waste vinyl, and more specifically, improving cooling efficiency to produce high-quality pyrolysis oil. In addition, the by-product gas generated in the pyrolysis process of waste relates to a condenser for an emulsification device provided so that it can be reused as an auxiliary fuel.

Polymer materials such as plastics and vinyls, which are being developed for various purposes, have increased emissions due to industrial development, and most are being disposed of by incineration and landfill. The development of new waste treatment technology is required.

As an example, it is a recycling method of polymer waste such as waste plastics and vinyl manufactured using petroleum as a raw material. Heat is applied in a reducing atmosphere without oxygen to cause a decomposition reaction in which the carbon chain constituting the polymer is broken, changing it into several low-molecular substances. As the waste is dissolved and vaporized, it is liquefied through a cooling device to obtain pyrolysis oil again. Some hydrocarbons break their bonds even at 200℃, and when the temperature is raised to 350~400℃, violent thermal decomposition reaction occurs.

Such an emulsifying apparatus includes a batch type in which waste is heated and melted from the outside in a state in which it is charged, and a continuous type in which waste is continuously put into the pyrolysis furnace and continuously pyrolyzed while being heated from the outside.

The condenser used in such a conventional emulsifying device has problems such as it is difficult to remove tar generated in the condensation process of cooling and liquefying the oil vapor, and the oil vapor leaks in the process of thermal expansion and contraction of the condensing facility, resulting in a safety accident.

Therefore, it is urgent to develop a condenser that can be used universally in the batch emulsifier and the continuous emulsifier and has high heat exchange efficiency.
