Description

It is a kind of based on the Biohazard Waste processing system of plasma gasification technology and processing Method

Technical field

The invention belongs to environmental technology field, and in particular at a kind of Biohazard Waste based on plasma gasification technology Reason system and processing method.

Background technology

Clinical waste or other hazardous wastes refer to have directly or indirectly toxicity, infectivity, it is damaging and other The waste of harmfulness.How safely and effectively to dispose with these innoxious wastes be always industry a great problem.It is useless for doctor, Most common processing mode is autoclaving sterilization and burning.Taken during but autoclaving sterilization can not fundamentally degrade, doctor is useless A large amount of plastics of band, and burning process can produce the secondary pollutions such as bioxin.

Gasification is the heat chemistry disposing technique between burning and pyrolysis.It can lack the organic component in waste With gasifying agent reaction generation synthesis gas under oxygen atmosphere, inorganic constituents is then excluded in the form of lime-ash.Compared with burning, gasification process With energy regenerating utilization rate is high, secondary pollution is small, flying dust is few, the advantage such as tail gas yield is low, equipment for after-treatment is simple.But Current gasification process there is also some problems in doctor is useless and dangerous waste processing is applied.

Typically gasification is carried out with melting process in a plasma body of heater in the prior art, can be due to plasma collection Sintering, bridging problem caused by middle heating, are difficult to control；The impurity such as tar can be carried in the crude synthesis gas that gasification furnace comes out, These impurity need refining treatment, and reform thermal degradation or catalyzed conversion using addition Secondary Air more than common refining route, Or but both modes exist reduction flow rate the problem of, or exist catalyst poisoning failure it is unstable because Element.

The content of the invention

It is useless there is provided a kind of medical treatment based on plasma gasification technology it is an object of the invention to solve above-mentioned technical problem Gurry processing system, with realize have it is safe efficient, stably, durable and low cost operation feature doctor it is useless/dangerous waste gasification process System.

Technical scheme：

A kind of Biohazard Waste processing system based on plasma gasification technology, including pusher feeder, revolving burner core type gas Change stove, cyclone separator, synthesis gas plasma purifier and plasma melting furnace, the pusher storehouse of the pusher feeder goes out The charging aperture of mouth connection revolving burner core type gasification furnace, syngas outlet and the cyclone separator of the revolving burner core type gasification furnace connect Logical, the ash-scraper of the revolving burner core type gasification furnace bottom connects conveyer, the conveyer and plasma fusion incinerator It is connected, the syngas outlet of the cyclone separator is connected with synthesis gas plasma purifier, the cyclone separator Bottom with being connected in the middle part of conveyer.

Further, the synthesis gas plasma purifier, including horizontal cylindrical section combustion chamber, with chamber front end The centrum section being connected, the cylindrical shape exhanst gas outlet section with the perpendicular connection in combustion chamber rear end, the fixation being connected with combustion chamber Support：The centrum section includes hollow cone, synthesis gas inlet pipeline, plasmatorch and natural gas combustion nozzle, the open circles The tip connection synthesis gas inlet pipeline of cone, its junction is provided with spiral flow deflector, the plasmatorch and natural gas combustion nozzle Horizontal symmetrical is arranged on the both sides of cone；The cylinder of the combustion chamber and exhanst gas outlet section is externally provided with steel shell external jacket, Spiral aviation baffle, the external jacket connection main feed pipe road of chamber front end, the main feed pipe road are provided between external jacket and cylinder On be communicated with four time air supply lines, the port closed of described air supply line and the periphery that cylinder is looped around for circular passage.

9. processing system according to claim 1, it is characterised in that the junction of the cyclone separator and conveyer is also Provided with two grades of blade type valves.

10. handling the method for Biohazard Waste based on the processing system described in claim 1-9 any one claims, it is special Levy and be, including following several steps：

1）Pusher feeder is sent into Biohazard Waste, Biohazard Waste push-in is rotated combustion chamber by the pushing piston of pusher feeder Formula gasification furnace；

2）Gasification reaction generation crude synthesis gas and bottom ash occur in revolving burner core type gasification furnace for Biohazard Waste；

3）Step 2）Syngas outlet feeding cyclone separator of the crude synthesis gas of generation on revolving burner core type gasification furnace, bottom ash Enter conveyer after the discharge of revolving burner core type gasification furnace bottom；

4）Crude synthesis gas is separated into synthesis gas and flying dust by cyclone separator, and the synthesis gas is refined into synthesis gas plasma Device, the flying dust enters conveyer；

5）Into conveyer flying dust mixed with the bottom ash after enter plasma melting furnace carry out melt process, ultimately generate Innoxious glass-like body slag and carrier gas；The synthesis gas generates harmless after the refining of synthesis gas plasma purifier Micro-molecular gas.
