Solid Discharge Products

Li2S204 being the SEI component at the Li anode and the solid discharge product at the carbon cathode. The Li—SOCI2 and Li—SO2 systems have excellent operational characteristics in a temperature range from —40 to 60 °C (SOCI2) or 80 °C (SO2). Typical applications are military, security, transponder, and car electronics. Primary lithium cells have also various medical uses. The lithium—silver—vanadium oxide system finds application in heart defibrillators. The lithium—iodine system with a lithium iodide solid electrolyte is the preferred pacemaker cell.

In heating or drying applications, when cooling of the product is desired before discharge to the atmosphere, cool air is blown through a second annular space, outside the inlet hot-air annulus, and released through the louvers at the solids-discharge end of the shell. 

The residue was ejected intermittently by a double lock discharge system illustrated in Figure 20. It featured two piston valves ( ram valves ) and an intermediate chamber. With the first ram valve open and the second ram valve closed, the chamber was filled with both solids and product vapor at the operating pressure of the reactor. Then the first ram valve was closed and the second ram valve was opened, thus leading to an ejection of the chamber content into a cyclone, where the solids were separated from the vapor.

To cool the rotor, air is pulled into the casing of the unit and leaves through a frame drain. This air can be a biohazard depending upon the nature of the product. It is therefore recommended to seal the solids discharge frame drain to the solids collection vessel. This air can then be exhausted and handled as waste. Bearings of course, as with any centrifuge, will need to be changed, preferably on a preventive-maintenance basis. 

The formation of the solid polymerized products, which takes place in parallel with fragmentation, as seen for cresol runs, requires considerably less energy. Study on the formation of polymer films starting with various monomers and using the present discharge system presents an extremely interesting problem which is currently under investigation. The results will be published in the near future. 

The present work is the first in a series of investigations of the effect of functional groups on the nature of gaseous and solid decomposition products. The results of such measurements should ultimately support a model for decomposition in a microwave discharge. Further, solid polymers produced in various discharges have not in general been the subject of more than the most rudimentary characterization. The present work explores possible avenues of further characterization.
