Purified treatment, cyclone separator connects pyrolysis gas depurator, and molecule is processed by pyrolysis gas depurator.Pyrolysis gas purifies
Device is provided with heat-insulation layer, prevents from causing pyrolysis gas to condense because temperature is too low, and pyrolysis gas depurator is respectively equipped with heat smoke entrance, hot cigarette
Gas exports, and the outlet of heat smoke entrance, heat smoke is connected with heat-insulation layer, is provided with multilamellar baffle plate in heat-insulation layer, and baffle plate can increase hot cigarette
The gas holdup time, improve energy utilization efficiency.
Being provided with multi-group filter net and the multihole nozzle being correspondingly arranged with filter screen in described pyrolysis gas depurator, multihole nozzle connects
Lean Oxygen Generator, is filtered molecule carbon dust by filter screen, uses the side that noble gas is jetted indirectly in multihole nozzle
Formula removes absorption carbon dust on filter screen.
Being provided with compressor, impulse electromagnetic valve between described multihole nozzle and lean Oxygen Generator, compressor can increase gas pressure
Power, optimizes winding-up effect.
Side, described pyrolysis gas depurator bottom connects cyclone separator, and bottom is provided with wind stopping device, and wind stopping device prevents outside
Gas enters in pyrolysis gas depurator.
Described pyrolysis gas depurator is provided with access hole, conveniently keeps in repair equipment.
Advantages of the present invention and having the beneficial effect that
In the present invention, after pyrolysis gas is separated by cyclone separator, the pyrolysis gas containing a great deal of carbon granule enters heat
After solving gas purifier, before pyrolysis gas cools down, the molecule charcoal in pyrolysis gas is effectively separated, the most right after purification separation
Pyrolysis gas condensation liquefaction, improves quality of bio-oil.
Present system compact overall structure is simple, and with low cost, good operation stability, applicable amplification is promoted the use of.
