Description
Technical field：The present invention relates to plastics recycling technical fields, and in particular to a kind of recycling of waste plastics
System.Background technique：
" white pollution " is that people claim a kind of visualization of plastic garbage (more referring to polybag) pollution environmental phenomenon difficult to degrade
Meaning.And the waste plastic overwhelming majority in domestic waste is packing plastics or daily necessities container, such as food packaging, equipment packet
Dress etc..This solid waste is mostly made of high-molecular compounds such as polyethylene, polypropylene, polystyrene, polyvinyl chloride.It is all kinds of
Household plastic product is thrown aside using rear, is thrown out without care due to arbitrarily throwing out without care, it is difficult to degradation treatment, so that causing urban environment serious
The phenomenon that pollution is the main reason for causing cities in China " garbage-surrounded city " phenomenon in recent years.
Since the country mostly handles house refuse at present in a manner of landfill, waste plastics can not only occupy largely with garbage loading embeading
Soil, and occupied soil cannot restore for a long time, influence the sustainable use in soil.Into giving up in house refuse
If plastic products are filled, 200 years time cannot degrade.Burying for a long time can be such that soil property pH value produces in the soil
Changing, soil environment deteriorate the growth that can seriously affect crops.If livestock has eaten plastic foil, the alimentary canal of livestock can be caused
Disease, in addition it is dead.It shows according to the relevent statistics, it is total that the packaging material based on polyethylene and polypropylene film accounts for plastic garbage
60% or more of amount.If effectively sorted to both plastics in waste plastic film and resource utilization, sorting
The polyethylene and polypropylene opened have extremely objective regeneration value, also to handle the environmental pollution faced at present and rubbish
Processing problem provides a resolving ideas.But it is stronger for the specific aim of the recycling general technology of waste plastic at present,
Process route is complicated, it could even be possible to generating secondary pollution.
Summary of the invention：The purpose of the present invention is to overcome the deficiencies of the prior art, provides a kind of technics of reclaim of plastic waste benefit
With system, waste plastic after the recovery is put into cracking still, and adds corresponding catalyst, is flammable by cracking of waste plastics
Gas and liquid fuel oil, fuel gas are hydrogen and carbon monoxide, and liquid fuel obtains gasoline and diesel oil after refining, this
Invention have it is easy to operate, lysis efficiency is high, cracking is thorough, cracking process does not cause secondary pollution, ecological value with higher
Value and economic value, solve deficiency in the prior art.To achieve the above object, the present invention provides the following technical solutions：One
Kind recycling of waste plastics system, including the pretreatment of waste plastic pulverized particles, pellet, cracking still cracking, product separation etc.

Repeatedly clean 5-8 time by clear water clean to completely after plastic grain is dried；
（2）Pretreatment of particles；Through（1）Plastic grain, calcium oxide, benzene, dimethylbenzene after middle drying after mixing people's air defense enter it is double
In extruser, ratio 1：10：5：5, at 220-260 DEG C, extruder discharging mouth carries out the control of Twin screw extruder temperature
Heating, control heating temperature are identical as Twin screw extruder temperature；
（3）Cracking still cracking；The river sand of one layer of 50 mesh or so is uniformly laid in cracking still bottom, sand layer thickness 5-10cm, then
It will（2）In pretreated mixture and powdered carbon, copper powder, iron powder etc. be added in cracking still together, be put into ratio be 5：5：2：3,
Then cracking still is heated, controlled at 350-400 DEG C, opens cracking still blender, reacted after 1-1.5h to reaction
Catalyst is added in kettle, control temperature is passed through inert gas in 300-380 DEG C, heating process into cracking still, and intake is
The 1/2 of inventory in cracking still, obtained gas raw material, liquid charging stock and solid material after the reaction time is 2-4h；
（4）It will（3）The gas raw material of middle preparation is passed through condensing tower condensation, oil is made in condensed product after gs-oil separator
Phase product and gas-phase product, oil-phase product and gas-phase product again through after fractionating column system to product purify obtained vapour,
The gaseous products such as the oils such as bavin, kerosene product and hydrogen, carbon monoxide, hydrogen chloride, by the solid-liquid raw material in cracking still by solid
The propenyl benzene raw material of industry is made after liquid separator seperator and purification.
Preferably, the cracking still heating method is in such a way that heating and external heat in microwave combine to plastic grain
It is melted.
Preferably, the inert gas is carbon dioxide, water vapour and nitrogen, ratio 2：2：1.
Preferably, the catalyst is zeolite, bauxite, calcium oxide are mixed with, ratio 3：3：4.
Compared with prior art, beneficial effects of the present invention are as follows：Recycling of waste plastics system of the present invention, particle are pre-
Treatment process by mixed oxidization calcium remove part waste plastic it is heated after the hydrogen chloride gas that decomposites, extruder discharging mouth into
Row heating and addition benzene, dimethylbenzene increase it is heated after the plastic flow property melted, cracking still bottom is laid with layer of sand, addition powdered carbon,
The raw materials such as copper powder, iron powder are the temperature in order to which temperature to be risen to plastic cracking as early as possible, are heated evenly plastics, play simultaneously
Certain catalytic action is passed through inert gas in cracking still and plays certain lubricating action, prevent inside cracking still slagging and
It is adhered, the oxide in catalyst is to prevent corrosion cracking still to neutralize and crack product hydrogen chloride in cracking still, and catalyst is more
Pore structure accelerates the cracking of plastics.
