Abstract
The invention discloses a system for recovering waste plastics. The system comprises a pyrolysis device, a raw material breaker, a cooler, a granulator and a deep cooling device, the pyrolysis device is provided with a raw material inlet, a gas outlet and a waste outlet, the raw material inlet of the pyrolysis device is connected with the raw material breaker, the gas outlet is connected with a condenser, and the waste outlet is connected with the granulator; and the cooler is provided with a gas outlet, the gas outlet is connected with the deep cooling device, the system also comprises a filter, the gas outlet of the pyrolysis device is connected with the inlet of the filter, and the gas outlet of the filter is connected with the inlet of the cooler. The system for recovering waste plastics provides a new idea for recovering waste plastics; and the filter is arranged between the pyrolysis device and the cooler, and the direction of every stage material is adjusted, so pollution of the system to environment is effectively reduced.
Description
Technical field
The invention belongs to petrochemical industry, relate to a kind of system recycling waste or used plastics, be specifically related to a kind of waste or used plastics of recycling and produce the device of oil gas.
Background technology
The natural degradation cycle of waste or used plastics, generally up to 500～1000 years, often results in pollution in wide area.The method recycling plastics is seen in various document already, but still suffers from present processing waste or used plastics with original combustion method, and open burning often results in serious secondary pollution, it is necessary to firmly stopped；In numerous plastics recovery processing methods, utilize waste or used plastics to produce oil gas and there is good development prospect.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of system recycling waste or used plastics.
A kind of system recycling waste or used plastics; including pyrolysis installation, raw material breaker, cooler, comminutor and cryogenic system; described pyrolysis installation is provided with feed(raw material)inlet; gas outlet and waste outlet; the feed(raw material)inlet of described pyrolysis installation is connected with raw material breaker; gas outlet is connected with cooler, and waste outlet is connected with comminutor；Described cooler is provided with gas outlet, and described gas outlet is connected with cryogenic system.
Preferred as this programme, also includes filter, and the gas outlet of pyrolysis installation communicates with the entrance of this filter, and the gas outlet of this filter is connected with cooler entrance.
Preferred as this programme, described filter is additionally provided with solids outlet, and the outlet of described solid waste is connected with pyrolysis installation.
The beneficial effects of the present invention is: the present invention recycles the system of waste or used plastics, provide a kind of new approaches recycling waste or used plastics, the present invention is provided with defecator between pyrolysis installation and cooler, and materials at different levels trend has been adjusted, effectively alleviate the method pollution to environment.
Accompanying drawing explanation
In order to make the purpose of the present invention, technical scheme and beneficial effect clearly, the present invention provides drawings described below to illustrate:
Fig. 1 is that the present invention recycles waste or used plastics system schematic.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
Embodiment 1:
As shown in Figure 1; the present embodiment recycles the system of waste or used plastics; including pyrolysis installation, raw material breaker, cooler, comminutor and cryogenic system; described pyrolysis installation is provided with feed(raw material)inlet; gas outlet and waste outlet; the feed(raw material)inlet of described pyrolysis installation is connected with raw material breaker, and gas outlet is connected with cooler, and waste outlet is connected with comminutor；Described cooler is provided with gas outlet, and described gas outlet is connected with cryogenic system.
In the present embodiment, also including filter, the gas outlet of pyrolysis installation communicates with the entrance of this filter, and the gas outlet of this filter is connected with cooler entrance.
In the present embodiment, described filter is additionally provided with solids outlet, and the outlet of described solid waste is connected with pyrolysis installation.
During use, first with raw material breaker, waste or used plastics is crushed to micron order mix homogeneously, then plastic powders is imported pyrolysis installation and heats to about 400 DEG C, at this moment the organic component in plastics volatilizees and enters filter and filters, gained gas enters chiller, and solid returns pyrolysis installation (dust brought into by the gas of pyrolysis installation has stronger toxicity), entering the gas part liquefaction after cooling of chiller, another part gas goes successively to cryogenic system cooling.
The present invention is provided with defecator between pyrolysis installation and cooler, and materials at different levels trend has been adjusted, and effectively alleviates the method pollution to environment.
What finally illustrate is, preferred embodiment above is only in order to illustrate technical scheme and unrestricted, although the present invention being described in detail by above preferred embodiment, but skilled artisan would appreciate that, in the form and details it can be made various change, without departing from claims of the present invention limited range.
