Abstract
The invention relates to a method for preparing petroleum liquefied gas by waste plastics, consisting of cracking kettles, a heater arranged at the lower end of the cracking kettle, a slagoff device, a reactor communicated with the cracking kettle through a pipe, a fractionating tower communicated with the reactor through a pipe, a condensing tower and a tower bottom can communicated with the fractionating tower through pipes and a gasoline outlet and a diesel oil outlet respectively connected with the condensing tower and the tower bottom can, wherein, a melting kettle and a bunker are arranged above the cracking kettle; a pipe which is led out from the fractionating tower is communicated with a heater so as to guide petroleum liquefied gas into the heater. With the melting kettle jacket and the recycle of petroleum liquefied gas, the invention increases thermal efficiency of equipment and saves energy sources.
Description
Technical field
The present invention relates to a kind of method of utilizing waste or used plastics to prepare oil liquefied gas.
Background technology
Utilize the existing device of waste or used plastics continuous production of petroleum generally can't reclaim liquefied gas and make postcombustion.
Adopt single still system, promptly adopt a reactor to finish drying, fusing and the cracking process that the waste or used plastics serialization is made, can't realize continuous operation, production efficiency is low, can't reclaim liquefied gas and make postcombustion.The requirement of incompatibility modern industry.Promote reinforced not only complex operation, and process is discontinuous.Single reactor production catalyzer therein must stop in the time of need bringing back to life regeneration producing, and causes waste.Do not have when stirring mechanism is arranged, waste or used plastics is easy to twine parcel, the about irregular phenomenon of agreeing with being heated.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned existing device, and provide a kind of can the serialization oil, and process is unimpeded, safety performance is good, the waste or used plastics that utilizes that thermo-efficiency is high prepares the method for oil liquefied gas.
Purpose in the time of this can reach by following measure: a kind of method of utilizing waste or used plastics to prepare oil liquefied gas, by cracking still, cracking still, the well heater of lower end, slag discharging device, reactor by pipeline and cracking UNICOM, separation column by pipeline and reactor UNICOM, condensing tower by pipeline and separation column UNICOM, jar at the bottom of the tower, and jar picks out at the bottom of condensing tower and the tower respectively fuel dispensing outlet and diesel oil export mixes, above cracking still, be provided with melting kettle and feed bin, draw a pipeline in the separation column, with well heater UNICOM, oil liquefied gas is introduced in the well heater.
The present invention has the following advantages: (1) adopts the hydraulic pressure feed mechanism that agitator is set in melting kettle, use the plug valve slagging device, the measure that is provided with manifold in the circulating oil path has guaranteed that flow process is unimpeded, has not only improved production efficiency, and the device security performance improves greatly.(2) increase melting kettle and feed bin, adopt the feeding of blower structure, the double-reactor parallel connection guaranteed that equipment gives birth to serialization, make it to adapt to the large-scale industrial production needs.(3) employing of melting kettle chuck and recycle of petroleum liquefied gas have improved device heat efficiency, have saved the energy.
Embodiment
A kind of method of utilizing waste or used plastics to prepare oil liquefied gas, by the well heater of cracking still, cracking still, lower end, slag discharging device, reactor by pipeline and cracking UNICOM, separation column by pipeline and reactor UNICOM, jar at the bottom of condensing tower by pipeline and separation column UNICOM, the tower, and jar picks out at the bottom of condensing tower and the tower respectively fuel dispensing outlet and diesel oil export mixes, above cracking still, be provided with melting kettle and feed bin, it is characterized in that: draw a pipeline in the separation column, with well heater UNICOM, oil liquefied gas is introduced in the well heater.
The heating of melting kettle inside relies on wherein tubulation inside from the hot gas of cracking still on the one hand, fix an insulation heating jacket not on the one hand around, it has been enclosed in wherein, increased the heating surface area of plastics, because this chuck is made with lagging material, played insulation effect simultaneously.
The melting kettle upper end is feed bin fixedly.The waste or used plastics that falls from feed bin enters the melting kettle by the hydraulic pressure feed mechanism, Hydraulic Station is by the piston advance and retreat of pipeline valve control hydraulic cylinder, piston is by connecting rod glassware fixed connection, its advance and retreat end opening place's pipe laying and melting kettle connect, suction hot blast from melting kettle wherein communicates with feed bin one side opening by feeding tube, connects to expect that the lower end of pipe offers a charging opening, waste or used plastics therefrom adds, and imports under hot blast drives among the feed bin.
Cracking still connects by pipeline and valve and separation column by pipeline and valve and reactor
Separation column has three outlets, one is by pipeline and valve and condensing tower connection, condensing tower is again by pipeline and valve and fuel dispensing outlet connection, discharge gasoline by fuel dispensing outlet, it two connects by pipeline and valve and reactor, jar connection at the bottom of its threeway piping and valve and the tower, and pipeline therebetween stretches into that jar partly is a swan neck at the bottom of the tower, jar by pipeline and valve and diesel oil outlet connection, is discharged diesel oil by the diesel oil outlet again at the bottom of the tower.
Claims (2)
1. method of utilizing waste or used plastics to prepare oil liquefied gas, it is characterized in that: by the well heater of cracking still, cracking still, lower end, slag discharging device, reactor by pipeline and cracking UNICOM, separation column by pipeline and reactor UNICOM, jar at the bottom of condensing tower by pipeline and separation column UNICOM, the tower, and jar picks out at the bottom of condensing tower and the tower respectively fuel dispensing outlet and diesel oil export mixes, above cracking still, be provided with melting kettle and feed bin, draw a pipeline in the separation column, with well heater UNICOM, oil liquefied gas is introduced in the well heater.
2. the method for utilizing waste or used plastics to prepare oil liquefied gas as claimed in claim 1 is characterized in that: fixing one deck insulation jacket around the melting kettle.
