Patent ID: 8486181

Claim:
A method for making a slow releasing device for slowing releasing chlorine dioxide comprising: sending gaseous chlorine dioxide into a receiving container containing a plurality of particulate carriers, with each of the plurality of particulate carriers having a plurality of pores in a surface thereof, with the receiving container placed in a low-temperature environment below 30° C., with the gaseous chlorine dioxide absorbed by the plurality of particulate carriers; packaging the plurality of particulate carries in at least one container; and sealing said at least one container; wherein sending said gaseous chlorine dioxide into the receiving container further including sending gaseous chlorine dioxide from a gaseous chlorine dioxide generating source through an inlet pipe and passing through the gaseous chlorine dioxide through a purifying unit to purify the gaseous chlorine dioxide before entering the receiving container, with an outlet pipe connected to the receiving container, with superfluous gaseous chlorine dioxide not absorbed by the plurality of particulate carriers exiting the receiving container via the outlet pipe, with a circulating pipeline including a venturi connected to the outlet pipe, with a circulating pump mounted on the circulating pipeline and creating a suction force at the venturi, with an absorbing tank mounted on the circulating pipeline, with the absorbing tank capable of receiving water for dissolving or absorbing the superfluous gaseous chlorine dioxide.
