Description

CONTINUOUS PYROLYSIS PETROLIZING APPARATUS FOR CONTROL OF THERMAL EXPANSION OF PYROLYSIS REACTOR}

The present invention relates to a continuous pyrolysis emulsifying apparatus, and more particularly, to a continuous pyrolysis emulsifying apparatus capable of thermal expansion control of a pyrolysis furnace to produce refined oil by thermally decomposing polymer waste such as waste plastic and vinyl by heating. will be.

Currently, plastics and vinyl, which are polymer materials composed of hydrocarbons used for various purposes, have increased emissions due to industrial development, and most of them are disposed of by incineration and landfill, causing serious environmental pollution such as air, soil, and ocean. As a result, new treatment technology for polymer waste is required.

In addition, due to the recent increase in oil prices, various measures for the cyclical use of resources have been devised, and thus, an emulsifying apparatus technology for recycling various types of waste plastics has been activated. For example, by recycling waste plastics such as waste plastics and vinyl, which are made of petroleum as a raw material, heat is applied in a reducing atmosphere without oxygen to cause decomposition reactions in which the carbon chain constituting the polymer is broken, thereby changing to a plurality of low molecular materials. As the waste is dissolved, it is vaporized and then liquefied through a cooling device to obtain refined oil again. Some hydrocarbons break their bonds even at 200 ° C, and violent pyrolysis occurs when heated to 350-400 ° C.

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

A cooling device 30 for cooling and liquefying the gas oil separated by the gas, a gas storage part 40 for storing and liquefying the gas cooled by the cooling device, and a gas not liquefied by the gas storage part. A gas supply unit 50 for resupply to the heating furnace, a combustion gas outlet 60 for discharging waste combustion gas to the outside of the heating furnace 10, and a dust collector for separating and collecting fine characters contained in the combustion gas ( 70 and the combustion that has passed through the dust collector 70 There is a waste plastic and general waste plastic painting apparatus is disclosed that includes an exhaust fan 80 for discharging to the outside.

However, since a large temperature difference occurs because a high temperature combustion heat is supplied to the inside of the furnace to heat the furnace, a large length deformation occurs due to thermal expansion and contraction. If the heating furnace is installed in a fixed state and repeats the operation and stop of the pyrolysis, the heating furnace repeats thermal expansion and contraction, and the damage caused by cracking and deformation may occur, and the pipe may rupture or break away. Loudness or cracking can cause large safety accidents in which oil vapor can leak out.

In addition, the above-described conventional technology is troublesome and difficult to separate the input means and the pyrolysis furnace, it takes a considerable time, there is a problem that maintenance and inspection is inefficient.
