Description
Technical field
The present invention relates to pyrolysis installation, and in particular to a kind of pyrolysis for macromolecule organics such as worn-out agricultural film, plastics
Stove.
Background technology
Plastics are important organic synthesis high polymer materials, and using very extensive, but what waste plastic was brought " white is dirty
Dye is " also increasingly severe.
Plastics recycling mainly has the modes such as burning electricity generation, regeneration and renewable resources at present.It is wherein commonplace
Method be burning method, but due to generally containing the halogens such as Cl, Br in plastics, burning disposal can cause pole to surrounding environment
Its serious harm, and harm of the comburant to human body is huge, and in burning process, often with heavy metal, sour gas
The heavy contaminant compositions such as body, bioxin volatilize.And existing plastics burning facility generally existing poor continuity, high energy consumption, not environmentally
The defects of.
In order to solve drawbacks described above existing for prior art, the present invention utilizes organic matter pyrolysis principle, in anoxic or nothing
Under the conditions of oxygen, the chemical bond that is destroyed using the mode of heating between carbon containing high-molecular compound element, destroy compound in plastics,
Fuel gas is separated out, so as to reach while waste or used plastics are recycled, environmental protection, efficient, continuous production is realized and improves energy
The purpose of source utilization rate.
The content of the invention
It is an object of the invention to provide a kind of worn-out agricultural film plastics pyrolysis oven, makes plastics in anoxic or the condition of anaerobic
Under, the chemical bond that is destroyed using initial thermal energy between carbon containing high-molecular compound element, make the carbon compounds such as plastics destroy or
Chemical restructuring is carried out, the flammable cracking gas that pyrolytic goes out is realized and recycled.
The present invention is achieved by the following technical solutions:
A kind of worn-out agricultural film plastics pyrolysis oven, including shell, pyrolysis chamber, combustion chamber, stirring motor, diesel combustion machine, cracking gas
Pipeline；
Described pyrolysis chamber is fixed in shell, and the intermediate space between pyrolysis chamber and shell forms combustion chamber；
The bottom of the pyrolysis chamber is provided with ash hole, and top is provided with cracking gas outlet and feed hopper, and inside is fixed with welds thereon
There is the puddler of agitating paddle, puddler is driven by stirring motor and rotated；
Described top of combustion chamber is provided with exhanst gas outlet, and bottom is communicated with cracking gas mixing chamber and diesel combustion machine；
Described cracking gas outlet and cracking gas mixing chamber are by the cracking gas pipeline communication provided with burner, on the burner
Air intlet is provided with, is also reserved with the cracking feed channel and sets valvular cracking gas diverging mouth.
Further, fin is provided with the outer wall of described pyrolysis chamber, for strengthening the heat transfer property of pyrolysis chamber.
It is provided with cover plate on described feed hopper, during operation, pending worn-out agricultural film plastics is sent into from feed hopper and are pyrolyzed
Interior, after raw material is filled inside pyrolysis chamber, the cover plate covered on charging aperture is sealed.
Sight burner is provided with described shell, for observing the combustion case in combustion chamber.
Pressure gauge is housed, for measuring combustion chamber pressure on described shell.
The top of described pyrolysis chamber is fixed with thermometer, for determining the temperature in pyrolysis chamber.
The outside of the shell is coated with adiabator layer, and inside sets fire brick layer, for being incubated to pyrolysis oven
And accumulation of heat.
The bottom of the shell is provided with bearing, for pyrolysis oven and ground to be fixed.
In use, pending plastics are sent into pyrolysis chamber by feed hopper first, after raw material is filled inside pyrolysis chamber,
Cover plate is covered to be sealed；Pyrolysis oven initial heating is heated using diesel combustion machine, starts stirring motor while heating,
Drive agitating paddle inside pyrolysis chamber to rotate, be heated evenly raw material；In the case of diesel combustion machine constantly heating, pass through temperature
Flammable cracking gas is begun with when meter observation pyrolysis chamber's thermometer reaches 650-750 DEG C, inside pyrolysis chamber to separate out；Pyrolysis chamber separates out
Cracking gas by cracking gas pipeline to burner, cracking gas and the air that air intlet enters cracking it is gas mixed enter
Row is delivered to enclosure interior combustion chamber after being sufficiently mixed is burnt, and the heat of release is used for heating of plastic pyrolysis and does what is needed
Energy, it can now close diesel combustion machine；When combustion chamber separates out without cracking gas, the pyrolysis of combustion chamber raw material is completed,
Lime-ash after the completion of plastics pyrolysis carries out ash discharge by ash hole, and lime-ash can be used for construction material or roadbed material.
The present invention can realize the nuisanceless disposal of waste or used plastics product, simple in construction, cost is low, save the energy, protection
Environment.
