Description

Oil creation device of waste synthetic resin

The present invention relates to an emulsifying device for waste synthetic resin, and in particular, improves the production efficiency of recycled oil, reduces the amount of waste discharged, solidifies the untreated residue in the reactor to a certain size and reuses it as fuel of a heating device such as a boiler. It relates to an emulsifying device for waste synthetic resin.

Waste synthetic resins such as PE, PP, PS, and PVC are less recyclable and most of them are disposed of as waste, so it takes a long time to decompose into a natural state. New energy development is required.

Accordingly, various techniques for extracting oil through a fixed fixation have been proposed to prevent environmental pollution and to obtain and utilize energy, and the basic principle thereof will be described as follows.

Waste synthetic resins such as waste vinyl and plastic waste are petroleum, and gasoline, diesel, and liquefied gas are also extracted from petroleum. The raw material of the waste synthetic resin is a polymer having a large molecular weight and its composition is composed of carbon and water channels.

In addition, gasoline and diesel oils produced by oil refineries have a relatively small molecular weight and are also composed of carbon and hydrogen.

Accordingly, by converting the composition of the molecular weight, the waste synthetic resin can be converted into gasoline, diesel oil, gas, and the like. As a theoretical basis, the waste synthetic resin can be seen as solid petroleum having a very high molecular weight. It can be converted to oil.

Such cracking methods can be divided into pyrolysis and catalytic cracking processes using only heat, but recently, a process in which heat and catalytic processes are combined has been studied.

Simple pyrolysis process is a simple process and easy to operate, many studies have been conducted, and can be divided into atmospheric pyrolysis, pressurization pyrolysis, hydrogenation process, reforming operation.

It is known that pyrolysis processes can obtain decomposition products such as liquid fuels, gaseous fuels or syngas. However, these products have disadvantages such as wide molecular weight distribution of hydrocarbons and poor quality and process interruption due to carbon deposition.

On the other hand, the decomposition of plastics using catalysts has the advantage of lower recycling temperature, higher selectivity of decomposition products, and narrower molecular weight distribution than other conventional pyrolysis methods. There is room for improvement in terms of cost and process.

In addition, the pyrolysis temperature of plastics is unique to each plastic or the same kind, depending on the type, form, etc., and the influence of plasticizers or other fillers, and the presence of air pyrolyzing plastics, the presence of water vapor or inert gas. Decomposition products vary depending on the presence or absence of a catalyst or other chemicals, and in general, many kinds of gaseous oils and residues are produced.

In addition, the method of recovering chemicals is economically problematic when the cost of decomposition is more than the cost of the direct source, and the type of decomposition products also plays an important factor in determining the economic efficiency of the process. In the case of fixed cost for collecting and storing, it has to be linked with additional treatment process, and the high boiling point mixture with long carbon chain has to be reformed and has a secondary environmental pollution when using catalyst. There was a problem such as causing.

In addition, since only one reactor is conventionally used, residues in the reactor must be removed in order to perform the next operation while the waste synthetic resin is heated in the reactor and the recycled oil is taken out. For this purpose, until the reactor is sufficiently cooled down, Waiting for about two hours and then having to perform the next task was causing a problem that will not keep the reactor running.

Accordingly, the present invention for solving the above problems is provided with two reactors for heating and melting the waste synthetic resin raw material to vaporize, the gas of the bunker oil, gas oil, gasoline components discharged from any one reactor currently operating Cooling is carried out at the temperature condition to form a cooling means for oil retention, producing a high quality recycled oil from the oil obtained by the cooling means through the process of separation of water, acid and sulfur components, etc. Sludge treatment means is formed to solidify the residue to a certain size, and the off gas and propane gas generated during oil re-use are reused as combustion raw materials of the heating burner, thereby improving regeneration oil production efficiency. It reduces the amount of waste discharged and solidifies the unprocessed residue in the reactor to a certain size. It is an object of the present invention to provide an emulsifying device for waste synthetic resin that can be reused as a fuel of a heating device.

It is rotated angularly to supply waste synthetic resin raw materials to the first and second reactors 2 and 3.

In addition, a separate air conditioning system is provided for purifying off gas and propane gas generated during the heat treatment process and discharging them into the atmosphere.

Referring to the operation of the present invention configured as described above is as follows.

First, the collected waste synthetic resin is crushed and cut to form a small size, and the crushed raw material is supplied to the first or second reactors 2 and 3 through the conveyor belt 1.

Here, the raw material is a thermoplastic resin PE, PP, polystyrene, ABS, acrylonitrile styrene, polyethylene terephthalate, polybutylene terephthalate, polyphenylene sulfite, polyphenylene oxide, polyacetal, polycarbonate, acrylic resin, Nylon, polyamide, expanded polyethylene, teflon, synthetic rubber, polyvinyl chloride.

In the present invention, since two reactors (2,3) are used, as a result of using any one of the reactors (2) and operating the other reactors (3) during the time that the reactor (2) is cooled as a whole The same effect as operating the reactor continuously can be expected.

When the heating burner 4 is operated while the waste synthetic resin raw material is supplied to the reactors 2 and 3, the raw materials in the reactors 2 and 3 start to melt, and when the temperature reaches a predetermined temperature, the gas is gasified. Hydrogen cracking (molecular separation) starts to occur, and at this time, the long chain polymer is cracked and low molecular weight is moved upward by the magnetic pressure to the first to third gas pipes (6 to 8) through the gas separation hopper (5). To be discharged.

At this time, since the installation heights of the first to third gas pipes 6 to 8 are different from each other, the first gas pipe 6 located at the lowest position according to the temperature and the specific gravity of the gas is used as the bunker oil. Gas of a light oil component is discharged to the second gas pipe 7, and gas of a gasoline component is discharged to the third gas pipe 8, and gas passing through each gas pipe 6 to 8 is formed at an inlet side thereof. It reacts while passing through the catalyst tower 14, and the wax component contained in the gas is absorbed and removed.

On the other hand, the gases passing through the first to third gas pipes 6 to 8 are cooled at different temperatures by the first to third coolers 9 to 11, respectively, and the bunker oil tank 12 and the first to be in a liquid state. 1 is supplied to the oil tank 13, the reason for cooling the gas of different components as the different coolers (9 to 11) as described above is to increase the oil picking efficiency by cooling to the optimum state.

Since the bunker oil stored in the bunker oil tank 12 is not commercially available, the bunker oil is again supplied to the reactors 2 and 3 to be gasified together with the waste synthetic resin, and the light oil and gasoline collected in the first oil tank 13 are mixed. It is supplied to the oil / water separator 17 through the first auxiliary tank 16 in a state.

At this time, the gas contained in the oil supplied from the first oil tank 13 to the first auxiliary tank 16 is collected and stored in the off-gas tank 15, the gas stored in the off-gas tank 15 Since the unconverted gas is not liquefied into the oil in the second and third coolers 10 and 11, the gas is reused as a fuel of the heating burner 4 so as to reduce the atmospheric emissions of the off gas and propane gas. It was.

The oil / water separator 17 separates and removes moisture contained in the regenerated oil supplied from the first oil tank 13, supplies regenerated oil from which the water is removed, to the second oil tank 18, and the second oil tank. 18 supplies the regeneration oil supplied from the oil / water separator 17 to the reaction tank 20 through the second auxiliary tank 19.

In the process of supplying regeneration oil from the reaction auxiliary tank 22 to the third auxiliary tank 24, sludge contained in the regeneration oil is removed, decolorized and deodorized by the filter unit 23 interposed therebetween. It is supplied to the auxiliary tank 24.

The filter unit 23 is composed of a sludge filter, a deodorizing filter, a decolorizing filter, etc. In the present invention, the deodorizing efficiency is improved by using purified charcoal such as activated carbon as the deodorizing filter.

The third auxiliary tank 24 stores all of the regenerated oil supplied through the filter unit 23 in the oil storage tank 25, thereby generating all the regenerated oil from the waste synthetic resin.

On the other hand, the present invention has a function to automatically discharge the residue generated during the waste synthetic resin heating operation of the reactor (2,3).

Although waste synthetic resins are heated in the reactor to gasify, about 12% of the raw materials added to the reactor cannot be carbonized.

Therefore, in the present invention, when the maximum hydrogenation cracking occurred in the reactor (temperature in the reactor is about 300 ~ 400 ℃) to open the handle valve 31 formed in the lower part of the reactor (2, 3) Due to the high pressure in the reactor, liquid residue (a small proportion of oily substance including unvaporized liquid wax) present in the bottom of the reactor is discharged through the screw 32 installed in the discharge pipe 30, and discharged. The remaining liquid residue is discharged to the sludge tank 35 through the discharge port 33.

The liquid residue discharged to the sludge tank 35 is contained in the storage box 34 of the lattice structure, and when a predetermined time elapses in this state, the liquid residue is cooled and deformed into a solid having a certain shape. This solid mass (residue) can be usefully used as fuel for a boiler.

Therefore, in the present invention, waste such as residue does not occur.

As described above, the present invention has two reactors for heating and melting the waste synthetic resin raw materials and vaporizing them, and the gas of bunker oil, diesel oil and gasoline components discharged from any one reactor currently operating under different temperature conditions Cooling means to form oil cooling means, to produce high-quality recycled oil from the oil obtained from the cooling means through a process such as water separation, acid and sulfur components separation, the liquid residue in the reactor automatically By forming the sludge treatment means for solidifying to a certain size by discharging, it is possible to reuse the off gas and propane gas generated during oil regeneration as the combustion raw material of the heating burner, thereby improving the regeneration oil production efficiency, reducing the amount of waste discharged, The untreated residue in the reactor is solidified to a certain size to fuel the heating device such as a boiler. It can be expected an effect to provide a painting apparatus of the waste plastic to be reused.
