Description

Plastic waste thermolysis oiling system

[technical field]

The utility model relates to the system that plastic waste is carried out thermolysis, recovery fuel oil, particularly reclaims the system of fuel oil under the anaerobic passive state by the catalysis thermolysis.

[background technology]

Plastic waste is to be the compound of raw material production with the oil, is difficult for decomposing under state of nature.After disposing in the rubbish mode, the meeting contaminated soil causes environmental pollution.

Reclaiming fuel oil in plastic waste is the good method of contaminated solution.The oil-forming method of exploitation and equipment are once all raw materials to be put in fusion and the decomposition at present, so not only the resolving time is long, and the turnout instability of oiling gas, solve the growing amount that this defective can only corresponding increase oiling gas, facility investment will promote greatly like this, and returns of investment descend.

Moreover, owing to contain many impurity in the raw material, be not easy to remove before dropping into oilization device, in disposable oiling process, can produce impurity and pile up, need to interrupt normal oiling operation, processing temperature is cooled to normal temperature after, handle the impurity stores.Dispose, heat up again.So, not only increased tooling cost, and efficient reduces.

[summary of the invention]

Order of the present utility model is, at above-mentioned defective a kind of supplying clean raw material continuously is provided, plastic waste thermolysis oiling system under the anaerobic passive state.

The purpose of this utility model is achieved in that melting furnace, decomposing furnace, a secondary decomposing furnace, send oil pipe, high temperature catalyst reactor, knockout tower, air-cooler, cooled and solidified device, fuel oil storage tank to connect successively, it is characterized in that: further comprising under conveyer that pulverizer, turbine fly-ash separator, wire netting constitute, the wire netting magnet, vibrations sifting machine, storage tank, rotation batch charger, catalyzer weight feed device arranged, drop into two inflators, melting furnace connects successively.Working process is: raw material at first passes through pulverizer, be ground into 30～80mm, with the raw material after pulverizing send into can removal of contamination the turbine fly-ash separator, when the conveyer that constitutes by wire netting, magnet is arranged to remove the iron contamination in the raw material under the wire netting, sift out the raw material of cleaning once more through the vibrations sifting machine, send into storage tank, by shaking(-pan) conveyer raw material is supplied with the rotation batch charger continuously, drop into catalyzer simultaneously, and outside cutting off, continuously raw material supplying is dropped into two inflators under the state of gas, the melting furnace of built-in rotating paddle, a decomposing furnace of built-in rotating paddle, behind the secondary decomposing furnace, fuel oil enters knockout tower by sending oil pipe, isolated gasoline in the knockout tower, pass through air-cooler, enter the gasoline storage tank through the first cooled and solidified device again, isolated diesel oil in the knockout tower enters the diesel oil storage tank by the second cooled and solidified device.

The utility model compared with prior art, increased before oiling to raw material carry out clean, and continuous dosing, oil yield is obviously improved, cost obviously descends, and is environmental.

[description of drawings]

Further specify the utility model below in conjunction with accompanying drawing.

Fig. 1 is the utility model manufacturing process schema.

Fig. 2 is a system of the present utility model pie graph.

[embodiment]

Be mixed with 10～80% foreign substances during waste plastics recovery, insufficient processing will reduce oil yield, and accumulating also of the impurity that is in operation can be hindered production efficiency.

Raw material at first passes through pulverizer 110, be ground into 30～80mm, with the raw material after pulverizing by gas blower 120 send into can removal of contamination turbine fly-ash separator 130, when passing through the conveyer 140 that constitutes with wire netting, magnet 141 is arranged to remove the iron contamination in the raw material under the wire netting, sift out the raw material of cleaning once more through vibrations sifting machine 150, send into storage tank 170, by shaking(-pan) conveyer 180 raw material is supplied with rotation batch charger 190 continuously, drop into catalyzer by catalyzer weight feed device 191 simultaneously, drop into two inflators 220 and will cut off extraneous air, prevent the thermosteresis of melting furnace.The raw material of melting furnace 210 of putting into built-in rotating paddle 211 is with the fused state, acts on for the first time that decomposing furnace 220 and first catalyzer promote to decompose, undecomposed dissolving raw material the second time decomposing furnace be decomposed into oiling gas fully.

Melting furnace 210 and first, second decomposing furnace 220,230, the high temperature air of supplying with from high temperature air supply machine 231 is supplied to and reclaims the round-robin indirect heating line by line.High-temperature Air Generator 231 will generate 600～700 ℃ high temperature air, make in the fusion 300～400 ℃, 400～500 ℃ of decomposing furnaces, the control device of each supply that the secondary decomposing furnace is 500～600 ℃.The oiling gas of secondary decomposing furnace behind catalyst reaction machine 233 neutralizations second catalyst reaction, arrives knockout tower 260 through sending oil pipe 232.In the isolating oiling gas of knockout tower, mink cell focus is by recovery tube 261, put into decomposing furnace once more No. one time, two kinds of the separating of oil one-tenth of high-grade fuel, store the first fuel storage jar 300 through air-cooler 270 and the first cooled and solidified device 280 for one, another stores the second oil fuel storage tank 310 through the second cooled and solidified device 290.Here first oil fuel is to censure gasoline, and second oil fuel is to censure diesel oil.
