Description
Technical field
It the utility model is related to waste or used plastics process field, and in particular to a kind of worn-out agricultural film process in plastics device.
Background technology
Plastics have excellent combination property, easy to process, the advantages that significantly can saving the energy in production and use, because
This is widely used among industry, agricultural and daily life.But thing followed waste or used plastics product is brought
Environmental pollution has become increasingly serious, plastics can pollute after discarded to environment and the ecosystem.So-called " white pollution " is
Refer to a large amount of light white polybags to abandon in natural environment, it is difficult to collect, handle and caused by environmental landscape pollute, discard
The plastic sheeting in field can influence plant root growth, arable land is run down；Meeting after the plastic flakes being scattered are eaten by mistake by animal
Cause physiological function not normal or even dead；The plastic products especially plastics such as polyvinyl chloride, acrylonitrile illumination, it is heated when can put
Go out hydrogen chloride, formaldehyde, the phenol even harmful substance such as bioxin, pollute air and underground water, threaten the health of the mankind, it is raw
During production foamed plastics the air ecological balance, therefore the recovery of waste or used plastics can be destroyed using CFC and freon
It is to maintain the follow-up only way of plastic industry sustainable development, and most economical effective method at present.
Technics of reclaim of plastic waste, which utilizes, at present mainly the mode such as regeneration and regenerated resources.Regeneration is mainly made
Various plastic products, regenerated resources are mainly used in burning electricity generation, but due to generally containing the halogen families such as Cl, Br member in plastics
Element, burning disposal such as emission is not up to standard to cause extremely serious harm to surrounding environment, and comburant is to the danger of human body
Evil is huge, also, in burning process, is often volatilized with heavy contaminant compositions such as heavy metal, sour gas, bioxin, to ring
Border also result in a certain degree of pollution.
The content of the invention
It is an object of the invention to provide a kind of worn-out agricultural film process in plastics device, solves sour gas caused by directly burning
The problem of gaseous contaminations such as body, heavy metal and bioxin, not only preserve the ecological environment, and reclaim fuel gas to improve energy
Source comprehensive utilization ratio, the energy is saved for society, creates benefit.
The technical solution of the utility model is as follows：A kind of worn-out agricultural film process in plastics device, including plastics pyrolysis oven, it is described
Plastics pyrolysis oven pyrolysis gas outlet connects cooler, and exhanst gas outlet connection Drying, fire end is connected with diesel fuel burner, described
Cooler connects gas storage tank by vavuum pump, and the Drying outlet connects gas scrubbing tower, the gas scrubbing tower
Gas vent is connected by the gas access of blower fan and smoke dust collector, the outlet connection chimney of the smoke dust collector.
Preferably, the plastics pyrolysis oven is external heated fixed-bed plastics pyrolysis oven, makes plastics pyrolysis more abundant, improves modeling
The rate of recovery of material.
Preferably, the gas outlet of the gas storage tank is connected with the fuel gas inlet of plastics pyrolysis furnace bottom, makes combustion gas
Combustion gas inside air accumulator is passed directly into plastics pyrolysis oven internal-combustion through piping, and the heat of release is pyrolyzed for heating of plastic
The energy needed is done, can now close diesel fuel burner, reduces the input of other resources.
Worn-out agricultural film process in plastics device of the present utility model, plastics pyrolysis oven initial heating are carried out using diesel fuel burner
Heating, when plastics pyrolysis oven internal temperature reaches 650-750 DEG C, begin with flammable cracking gas and separate out, it is cold through subcooler
But some coercibility materials are precipitated and can be used as liquid fuel in cracking gas after, and the cracking gas not being condensed pressurizes by vavuum pump
It is stored in inside gas storage tank and is used as gaseous fuel；Plastics pyrolysis oven exiting flue gas pipeline is connected with Drying, flue gas warp
Drying cooling is crossed, the waste or used plastics being put into Drying are dried, the moisture inside Drying in waste or used plastics is steamed
Send out, the less and described Drying of the energy spent by dry waste mulching film plastics into pyrolysis formula in plastics pyrolysis oven
The flue gas discharged in plastics pyrolysis oven can be made full use of to carry out drying waste or used plastics, energy-conserving and environment-protective.
Pass through gas scrubbing tower containing acid gas component, flue gases such as HCl in plastics pyrolysis kiln gas of the present utility model
Afterwards, alkaline solution is fully contacted and reacted with the sour gas in flue gas inside described scrubbing tower, is caught in flue gas
Sour gas.
Smoke duster of the present utility model selects sack cleaner, can effectively catch dust in flue gas, and reduce
The content of heavy metal in flue gas, the heavy metal and dust that described smoke duster is collected can be used for construction material or roadbed material
Material.
Worn-out agricultural film process in plastics device of the present utility model, make the organic matters such as worn-out agricultural film plastics in anoxic or anaerobic
Under conditions of, the chemical bond that is destroyed using heat energy between carbon containing high-molecular compound element, make the carbon compounds such as plastics destroy or
Person, which carries out chemical restructuring and process, the imflammable gas that pyrolytic goes out, to be recycled after supercooling, can be directly used for giving birth to
Production, gas for domestic use, the flue gas that plastics pyrolysis oven excludes are harmful by sour gas, heavy metal etc. after supercooling, washing and dedusting
Material is dispelled, and flue gas finally passes through the direct qualified discharge of chimney.
