The detailed process that plastics are pyrolyzed:
Firstly, the waste plastic of collection is entered heat accumulating type rotating bed by pretreatment (for example, being crushed to certain partial size)
100, the fabric thickness of waste plastic can be 100mm, by adjusting the height of melting zone 16 and the spacing board 18 of pyrolysis zone 17
So that accommodation space is divided into two independent reaction burner hearths.
Then, the quantity that heat accumulating type rotating bed 100 can be opened and closed by control heat accumulation type radiant tube 19, so that melting zone 16
Temperature of charge at 300~360 DEG C (including endpoint value) Zuo You, the temperature of charge of pyrolysis zone 17 is at 500~600 DEG C of (including ends
Point value), to guarantee that in melting zone 16 heat fusing dechlorination can occur for waste plastic, pyrolysis then occurs in pyrolysis zone 17 and generates heat
Solve oil gas.Specifically, with the rotation of material bed 11, waste plastic enters to melting zone 16, in adding for heat accumulation type radiant tube 19
Under heat, waste plastic temperature can be promoted to 300~360 DEG C, and the fracture of C-Cl key occurs in pyrolysis melting zone 16, generates HCl etc.
Inorganic matter, these sour gas export 14 (for example, passing through air-introduced machine) through chlorine contained exhaust gas and draw, and by later period absorption tower by water
Absorption prepares the by-products such as hydrochloric acid.Waste plastic enters to pyrolysis zone 17, the reaction temperature of pyrolysis zone 17 after 16 dechlorination of melting zone
Degree can be 400~700 DEG C, the organic substance in waste plastic is largely decomposed into oil gas ingredient, by air-introduced machine from pyrolysis oil gas
The quickly export of outlet 15.Wherein, pyrolysis oil gas vent 15 can add oil gas catalytic unit, be catalyzed to plastics pyrolytic tar
Modification, to promote oil quality.Material conveying device can then be scraped through 13 row of discharge port by spiral by being pyrolyzed obtained pyrolytic carbon etc.
Out, for example, pyrolytic carbon can go out outside furnace body 1 by discharging spiral and the double coolconveyer cooling heel row of tube auger.
Wherein, the pyrolysis tail gas of melting zone 16 is directly sprayed through clear water, with the HCl etc. in absorbing reaction gas；Pyrolysis zone 17
Pyrolysis oil gas pass through oil gas catalytic unit, to pyrolytic tar carry out catalysis upgrading, then by ammonia spray to pyrolysis oil gas
Cool down, with separating tar and pyrolysis gas.Pyrolysis gas after purified treatment reuse to 19 combustion heat supplying of heat accumulation type radiant tube.
The major advantage of heat accumulating type rotating bed 100 according to an embodiment of the present invention is as follows:
(1) furnace body 1 is divided by melting zone 16 and pyrolysis zone 17, the heat that two regions generate by adjustable partition 18
It vents one's spleen and is quickly exported by independent air-introduced machine；Different using conversion zone temperature will remove out in waste plastics containing chlorine element in advance
Come, prevent the later period to the corrosion of consersion unit, avoids it from reacting with tar and generate the quality of organic chloride reduction tar；
(2) waste plastics heat fusing can be reacted by the setting of partition 18 and two independent oil gas guiding systems and heat
Solve reaction bonded together, having reduces equipment cost, guarantees the advantages of material steady and continuous is run；
(3) waste plastics pyrolysis is carried out using heat accumulating type rotating bed 100, by distribution device, the rotation of rotary hearth furnace bottom and spiral shell
The continuous operation that scraper guarantees waste plastic pyrolysis is revolved, avoids the problem that plastics are pyrolyzed coking and blocking reactor；Described
The downward concavity of revolving bed annular rotary table, plastic hot melt collect in reactor bottom and avoid flowing to water sealed tank 2 after melting.
