Description

 Waste plastic oiling device capable of continuous industrial mass production

 The present invention relates to a waste plastic oiling apparatus which can continuously produce industrially produced gasoline fractions, diesel fractions or high quality fuel oils and civil liquefied gases by catalytic or non-catalytic cracking using waste plastics or waste lubricating oils or heavy oils.

Background technique

 At home and abroad, the research and development of waste plastics oil technology has been more than 20 years old, and it is divided into two major categories: catalytic and non-catalytic cracking. However, in the case of large-scale continuous industrial production, the same difficult process and equipment problems were encountered. Until now, there have been few large-scale industrial production facilities with continuous and long-term operation at home and abroad. There are six main process equipment problems encountered: The first high-temperature feeding equipment: How to design a complete feeding equipment that can clamp a certain proportion of silt dust and water in a flammable and explosive atmosphere under cracking high temperature. The addition of waste plastics to the reactor is a primary equipment problem encountered in continuous production. The second high-temperature slagging equipment: How to design a safe slagging equipment to discharge the suspended silt impurities generated during the melting and the coke generated by the reaction in the cracking reaction process, and also form the continuous production. Necessary conditions. The third reaction heating problem, how to design a non-open flame heating reaction heating furnace, which can meet the requirements of improving flame temperature and radiation intensity, provide sufficient reaction heat, and must obey the flammable and explosive pressure vessel to prohibit open flame. Heating design specification requirements. The fourth design of an effective refining treatment equipment for pyrolysis oil, decolorization, deodorization and stability of the product, so that all the quality indicators meet the national standard requirements. In the fifth process, waste gas, waste water and waste residue are inevitably generated. How to design an effective secondary pollution treatment equipment and destroy them in the interior of the device is also an important process and equipment problem for the survival of the device. The sixth design has equipment to ensure safe production measures. This mainly refers to how to ensure the high temperature continuous feeding and slagging in the process of flammable and explosive high temperature reaction, such as feeding back gas protection, slagging fire prevention and Extinguish, container overpressure protection, eliminate tempering, etc., hardware equipment and measures.

 At present, Japan Fuji Recycling Company and POKODA Group Corporation Energy Materials Recycling Department are researching and developing waste plastic oiling technology. The first feature is that waste plastics are subject to careful sorting, washing and drying, extrusion molding, etc., and the processing steps are very complicated. It is huge; another feature is that melting and cracking are carried out separately, but the problem of solidification of molten plastic in the pump body and in the pipeline is not solved. Other companies are also vigorously conducting research and development, but they have not been able to form industrial-scale production facilities.

 In the United States, there was a research and development team led by Professor Mehdi Taghiei of the University of Kentucky. He has done a lot of research and obtained experimental research results. He affirmed the theory that high-quality fuel can be produced by cracking waste plastics. The feasibility of the experiment. But they use hydrogenation catalysis, the process is very complicated.

British BP and five European oil companies, in 1993 in the Scotland Ranchimouth refinery A small test unit with a processing capacity of 100 kg/h was built. This is a high temperature cracking unit for a fluidized bed sand furnace. It sprays the finely divided pieces of washed and pulverized waste plastic into a sand fluidized bed reactor at a high temperature of 400 to 900 ° C, and is cracked into a hydrocarbon mixture mainly composed of ethylene and propylene. Ethylene and propylene can be used as polyethylene and polypropylene monomers after precise separation and treatment. However, to date, no large-scale industrial installations have been put into production.

 Domestically, there are many small reactors for soil refining tank type cracking. Most of them cannot realize continuous operation, and it is impossible to achieve continuous feeding of enthalpy temperature, and it is not possible to discharge slag at high temperature, but it is carried out in one pot and one pot; the color and odor of oil products are Large, unstable nature, the quality does not meet national standards; secondary pollution is more serious, waste water waste slag emissions are discharged anywhere; production safety, lack of effective measures for personal safety, no guarantee.

Tie rod support. All the blades of the paddles 302, 303 are provided with a knife edge on both sides to break the coke block or the sintered plastic block in the liquid. This solves the problems in the previous design that the coke breeze block and the plastic frit block hit the stirring blade, block the exhaust pipe or cause the stirring motor to instantaneously overload and trip, or cause the reactor to vibrate strongly. An electric heating jacket furnace 404 is disposed around the reaction vessel 301 to provide heat required for the reaction; a vaporization-fractionator 306 is disposed on the top of the reactor head, and a cooling water coil 307 is disposed at the top of the reactor to provide internal reflux to generate the entire tower.

The utility model comprises a furnace skirt 401. A circular flame guiding sleeve 402 (as shown in FIG. 4) or six to eight flame guiding tubes 403 (shown in FIG. 5) are arranged around the skirt 401, and a ring around the reaction kettle 301 is arranged. The jacket furnace 404 and the combustion furnace 405 at the lower portion of the reactor 301 are in communication via a ring flame guide 402 or a flame tube 403. The heating device of the present invention is different from the conventional reaction combustion furnaces in that the flow section of the flame trap 402 or the flame guiding tube 403 is larger than twice the cross section of the jacketed furnace 404 around the reaction vessel 301. This reduces the flow resistance of the flue gas from the wide flow volume of the furnace and shortens the section, ensures the vacuum of the furnace and good combustion state, and prevents the furnace from generating positive pressure, which provides a guarantee for improving the furnace temperature. This design solves the problem that the flow path of the flame tube is small in the previous design, causing large resistance, low vacuum of the furnace, and even positive pressure combustion often occurs, the flame exits the furnace door, is unsafe, and limits the temperature increase of the furnace, so that the reaction is provided. Insufficient heat and other issues. A waveform thermal expansion joint 406 is disposed at the upper and lower ends of the flame shield 402 or the flame tube 403 (as shown in FIG. 4 and FIG. 5). Show), to absorb the thermal expansion stress, to ensure the normal operation of the furnace. This structure solves the problem that the expansion ring is seriously leaked in the previous design, the furnace vacuum is lowered, and the combustion is poor, which not only solves the problem of absorbing thermal expansion stress but also ensures the furnace sealing problem.

The plate 407 prevents the flame from directly contacting the reaction vessel 301, forming a non-open flame radiant heating mode. The design of the present invention is combined with the aforementioned large flame-conducting cross-section channel structure, which can not only allow a high furnace temperature, fully ensure the heat supply of the reactor, but also ensure the safe operation of the production, and fundamentally solve the flammability. Explosive reactors are not subject to the requirements of the design specifications for containers that are heated by open flame. The burner 408 used in the combustion furnace 405 is a mixed oil and gas type, and has the functions of automatic ignition, flame monitoring, flameout protection, etc., which are disposed on the lower part of the furnace and above the ash, and two burners are respectively disposed in the combustion furnace 405. On the side, the fire inlet is inclined in the direction of the furnace wall, so that the flame that is ejected forms a flame in the furnace, so that the heat of the flame trap 407 is more uniform. A flue gas outlet 409 is disposed at an upper portion of the reactor annular jacket furnace 404, and the derived flue gas can be removed from the jacketed furnace 102 of the hot press densification roll device 1 and the flue gas jacket 211 of the high temperature seal feeding device 2, and the like.
