Description

Waste synthetic resin emulsification processing equipment {OIL REVIVAL DEVICE OF DUST RESIN}

The present invention relates to a waste synthetic resin emulsifying apparatus, and more particularly, to a waste synthetic resin emulsifying treatment to thermally decompose various kinds of discarded thermosetting and thermoplastic synthetic resins to produce a high quality emulsified product that can be used as a fuel. Relates to a device.

As the industry develops and accelerates, a large amount of disposable products (plastic, polyester, vinyl, fiber, tires, fishing nets, styrofoam) are sold for the convenience of people, and more than 90% of these disposable products contain oil. One plastic or synthetic resin is used as the material.

Disposable products and vinyl made of these plastic and synthetic resin products are convenient for our lives, but are a major cause of serious environmental pollution.

As environmental pollution became severe due to the indiscriminate use of waste synthetic resins or plastic products, the government issued a special ban on the use of free plastic bags and disposable products in stores and stores to reduce the use of disposable or synthetic resins and plastic products.

However, despite the efforts of the government, environmental pollution by plastic and synthetic resins in our country has reached a serious condition.

As a result, about 6 million tons of waste synthetic resins are generated annually in Korea, of which about 1.5 million tons are recycled and the remainder is disposed of by incineration, landfill, or other methods, which pollute the environment. It causes a third environmental pollution and is facing a serious environmental pollution problem.

In view of the above problems, an emulsifying apparatus for extracting oil components by chemically treating and pyrolyzing waste synthetic resin is known in the art, but it is possible to process a large amount of waste plastic and waste synthetic resin at once even though maintenance and facility costs are expensive. Not only can it take a long time to process, but also has a disadvantage in that it is economically inefficient because oil extraction amount is only 30-40%.

In particular, when the high temperature pyrolysis is performed in a vacuum atmosphere for melting the conventional waste synthetic resin, there is a problem such as cooling the high temperature periodically with the risk of explosion.

The present invention has been proposed to improve the above problems in the prior art, by melting and purifying waste synthetic resin through low-temperature pyrolysis using indirect heat to prevent high energy reduction efficiency and risk factors in the process. It is an object of the present invention to provide an emulsifying apparatus.

Subsequently, the configuration of the refining line is followed by indirect heating of the melted mixed oil using a burner 22 to classify the refined tank 20 into light oil and heavy oil due to temperature variation, and hydrocarbons generated in the refinery tank 20. A second catalyst tank (23) for stabilizing paraffinic hydrocarbons and promoting hydrocarbon catalysts, and two sets of second cooling towers (24) for condensing purified light oil and heavy oil with cooling water supplied from a second cooling tank (26). ), A second oil and water separator 25 for separating the light oil and heavy oil from water, and a storage tank 30 in which the light and heavy oil from which water is separated are stored.

Between the first and second catalyst tanks 13 and 23 and the first and second cooling towers 14 and 24, first and second pressure balances 18 and 28 to adjust the pressure balance to move the reactant gas are respectively. Will be constructed. Reference numerals 17 and 27 represent first and second filters, respectively.

Meanwhile, as shown in FIG. 3, the melting tank 10 has an injection screw operated by the driving motor 6 in a state where the hopper 7 and the inlet 9 into which the waste synthetic resin is introduced are installed at the top ( 8) is built-in, the lower end is provided with a discharge port (5) so that the continuous discharge can be made by the discharge screw (4).

The effect of the operation of the processing apparatus of the present invention having such a configuration will be described.

First, when finely crushed waste synthetic resin (PP, PE, PS, etc.) is introduced into the hopper 7, the screw 8 is lifted along the inlet 9 by the injecting screw 8 rotated by the operation of the driving motor 6. After the injection into the melting tank 10 is made, the input of the waste synthetic resin is to be continuously proceeded to a certain amount.

The waste synthetic resin introduced into the melting tank 10 is thermally decomposed to low temperature (450-500 ° C.) by indirect heat applied from the burner 12 and cracked into low molecular materials to be liquefied and mixed by the mixing scraper 11. By becoming gasified.

The gas generated in this way is cooled by the pressure controlled by the first pressure balance 18 and sent to the primary cooling tower 14a to be liquefied, and the gas not liquefied in the primary cooling tower 14a is again converted into a secondary cooling tower. While passing through 14b, the mixed oil which is an oil component is liquefied and produced.
