Specific work process of the present invention is as follows:
180kg clinical waste is put into loading hopper 2, is broken into particle with broken roll 1, and fall into from loading hopper 2
On filter plate 43 in process container 4.
In hydrogen peroxide hold-up tank 51, the hydrogenperoxide steam generator that 30L concentration is 50% (w/w) is injected by charge pump
Oxidation solution allocates container 5.In ferrous hold-up tank 52,3 grams of green vitriols are dissolved in 10L water, are infused by charge pump
Enter in oxidation solution allocates container 5, and water is added to 600L.It is arrived simultaneously with the solution pH value that acetic acid adjusts oxidation solution allocates container 5
4-5。
In addition to blow valve (blow valve is arranged on the gaseous phase outlet of gas-liquid separator 45), it is each out to close process container 4
Entrance and valve start high pressure charging circulating pump 53 and heater 55, inject Fenton reagent in process container 4 in heating,
After Fenton reagent injection, blow valve is closed, opens the valve on filter 44, and cutoff high feed cycle pump 53 and oxidation
Valve between liquid allocates container 5 opens the valve that high pressure charging circulating pump 53 is directly arrived on threeway reflux line.Due to processing
Fenton reagent is filled in container 4, and temperature rises due to heating simultaneously, therefore the air pressure in process container 4 increases, opened
When valve on filter 44, the Fenton reagent in process container 4, which is subject to processing 4 air pressure inside of container and acts on, enters height through reflux line
It is pressed into material circulating pump 53 and constantly refills oxidation solution in process container 4.Reagent solution in constantly cyclic process,
Temperature constantly increases.
Meanwhile during circulation, since the outlet of feed pipe and the annular sidewall of reaction kettle are tangent so that from into
The Fenton reagent that pipe material exports out forms whirlpool in reaction kettle, then enters reflux line from whirlpool bottom, and waste
Grain is constantly overturn during just rotating again with whirlpool, is played the role of stirring (namely disturbance), is accelerated Fenton's reaction
Process.
With heating process, when temperature is stepped up to 100 degree in container, keeps the temperature and oxidation solution recycles 20 minutes, (following
Hydrogen peroxide, which is added, to oxidation solution allocates container 5 during ring is used as supplement) hydrogen peroxide charge pump is closed towards oxidation solution
The valve of allocates container 5 opens the valve that hydrogen peroxide is directly injected into return pipe, and 30L concentration is directly injected into return pipe is
