Referring to fig. 1, the mobile fractionation liquefying apparatus mainly includes a mobile carrier 10, a fractionating furnace 20, a burner 30, a feeding mechanism 40, a condensing assembly 50 and a generator 60.

In the embodiment, the movable carrier 10 is a container, but the utility model is not limited thereto, and the movable carrier 10 may be a carrier that facilitates various transportation methods, such as a trailer, a pallet, or a railway carriage. In addition, the number of the containers in this embodiment is two and the containers are stacked up and down, so that the longitudinal space can be increased to facilitate the effective distribution of the elements, but the number, size and connection mode of the containers can be adjusted correspondingly according to different requirements, so the present invention does not limit the number.

The fractionating furnace 20 is provided on a lower bin in the movable carrier 10. The fractionating furnace 20 is a hollow furnace body having a chamber 21 and an exhaust passage 22. The fractionating furnace 20 is provided with a plurality of heat pipes 23 and a plurality of heat-conducting partition plates 24 in the cavity 21. Each heat pipe 23 is arranged at the bottom of the cavity 21, and each heat conducting partition plate 24 is vertically arranged above each heat pipe 23, so that the waste plastics in the cavity 21 can be uniformly heated, the product purity is improved, and the efficiency is increased. The exhaust passage 22 is arranged at the top of the furnace body and extends into the container above, and the exhaust passage 22 is communicated with the cavity 21 so that high-temperature gaseous substances generated after fractionation can be upwards discharged out of the fractionating furnace 20 along the exhaust passage 22. Preferably, the mobile fractionation liquefaction apparatus of the present invention further comprises a dust collection filter tank 70 disposed in the upper container. The exhaust passage 22 is communicated with the dust collecting filter tank 70, so that the high-temperature gaseous substances generated after fractionation can reach preliminary filtration after being collected through the plug holes of the dust collecting filter tank 70 to reduce impurities.

The burner 30 is provided at one side of the fractionating furnace 20, and serves to heat the bottom of the fractionating furnace 20. Preferably, the lower container in the movable carrier 10 is provided with a closed combustion chamber 11, and the fractionating furnace 20 and the burner 30 are both disposed in the combustion chamber 11, so as to effectively isolate the high temperature generated by the burner 30, and to perform pyrolysis and fractionation of the waste plastics in an oxygen-free environment to improve the purity of the product.

The feed conveyor assembly 42 connects the bottom of the feed tank 41 and the top of the fractionating furnace 20, so that the waste plastics in the feed tank 41 are quantitatively fed to the top of the fractionating furnace 20 for charging. In the embodiment, the material conveying module 42 is a screw, but the utility model is not limited thereto, for example, the material conveying module 42 may be a conveyor belt or a shifting chain, as long as the effect of continuous quantitative material feeding can be achieved.

The condensation unit 50 is disposed in the upper container, and includes at least one high temperature condensation tank 51, at least one low temperature condensation tank 52, a gas temporary storage tank 53, an air pipe 54, and an oil pipe 55. In the embodiment, the number of the high temperature condensation tank 51 and the low temperature condensation tank 52 is two, but the utility model is not limited thereto. The exhaust passage 22 is communicated with the high temperature condensation tank 51 and the low temperature condensation tank 52, so that the high temperature gaseous substance collected and filtered by the dust collection and filtration tank 70 can enter the high temperature condensation tank 51 and the low temperature condensation tank 52 for liquefaction and condensation, wherein the substance stored after condensation in the high temperature condensation tank 51 is fuel gas, and the low temperature condensation tank 52 is diesel oil. The high-temperature condensation tank 51 is communicated with the gas temporary storage tank 53, and the gas pipe 54 is communicated with the high-temperature condensation tank 51, the gas temporary storage tank 53 and the burner 30, so that the gas in the high-temperature condensation tank 51 and the gas temporary storage tank 53 can be supplied to the burner 30 for use through the gas pipe 54. The oil pipe 55 connects the generator 60 and the low-temperature condensation tank 52, so that the diesel oil in the low-temperature condensation tank 52 can be supplied to the generator 60 through the oil pipe 55. Preferably, the oil delivery pipe 55 is also connected to the burner 30, so that it can be switched to supply diesel oil for combustion when the gas is insufficient. Therefore, the fractionated product can be effectively utilized to achieve energy self-sufficiency, so that the consumption of external energy is effectively reduced, and the cost is reduced.

The power generated by the generator 60 using diesel fuel is used to supply the whole fractionation and liquefaction apparatus, which is disposed in a container below. Preferably, the mobile fractionation liquefaction unit of the present invention may further include a purge gas column 80. The scrubber 80 has an exhaust pipe 81 connected to the generator 60, so that the exhaust gas generated by the generator 60 after burning diesel oil can be discharged to the scrubber 80 through the exhaust pipe 81 for treatment, thereby reducing or removing carbon dioxide (CO2), sulfur oxides (SOx), chlorine (Cl2), suspended Particles (PM), and the like in the exhaust gas, and discharging the remaining water (H2O) and low-concentration carbon dioxide (CO2) to the outside to avoid environmental pollution.
