In addition, the pressure for the dry air of the drying of discarded object is contemplated to be 0.1~1MPa or so.So-called pressure herein
Power is the pressure maintained in pressure vessel.If the pressure is below 0.1MPa, the moisture content of discarded object will not decline.And
And even more than 1MPa, the amount of money increase of equipment investment, but effect is less in terms of the shortening of drying time, additionally while
The moisture content of discarded object declines in pressure vessel, but the hydrolysis property of in general discarded object may not necessarily improve, in view of
In the case of the recycling (such as fertilizer, fuel) of hydrolysis process discarded object, the deterioration under high temperature is worried, thus it is improper.
This, on the pressure of dry air, is contemplated to be 0.1~1MPa or so, but on the pressure, if with pressure regulating unit 5A or
Person's pressure adjustment plug valve (not shown) described above is suitably adjusted.
Then, holding (maintenance) time as dry air in pressure vessel, it is contemplated to be 1 minute~3 minutes.If
Holding (maintenance) time is less than 1 minute, then the pressure transient of dry air.In addition, when holding (maintenance) time is 3
During the minute above, even if the pressure stability of dry air, dry efficiency also less improves, in addition, on the contrary, excessive sometimes
Dry influences the resistivity (such as less than 2900 Ω m) of discarded object on the contrary.
Then, in the system of the present invention, it is important that when holding (maintenance) of the setting dry air in pressure vessel
After time, the pressure release time for the pressure in pressure vessel to be returned to normal pressure (1 atmospheric pressure) is set.In addition, it is
Pressure release, the pressure in pressure vessel is returned into normal pressure, as long as carried out in such as Fig. 1 using pressure regulating unit 5A
Release.
In addition, on pressure release time, it is contemplated to be 1~2 minute or so.When the pressure release time is less than 1 minute
When, then according to the situation at random of the discarded object in pressure vessel, it is possible to which the action to the system of the present invention has an impact.Separately
Outside, when the pressure release time is more than 2 minutes, the moisture that can sometimes be taken into air and cause containing for discarded object
Water rate do not decline, the situation of (such as less than 2900 Ω m) is had an impact to the resistivity of discarded object.
