- PHYSICAL OPERATING PRINCIPLE The HSEDBH, operates on the physical principle of a control system or volume to which energy is delivered, by direct solar radiation, with consequent increase in the internal operating temperature, in accordance with the basic laws of calorimetry (first and second law of thermodynamics) so that the system to which it supplies heat - the sterilization chamber of the HSEDBH - should increase its internal temperature gradually to about 180 -200 0 C, being able to graduate between 160 -170 0 C, which they are higher than the threshold sterilization of bio-infectious waste temperature, which is about 135- 140 0 C for about 35 - 40 minutes.
- the sterilization time interval for safety reasons is at least 6 hours.
- the concentrated solar rays that the sterilization chamber receives and absorbs generate heat that is transferred by thermal conduction to the metal cylinders that contain the infectious - contagious waste, heat that finally reaches the waste itself, raising its temperature to a minimum of 160 - 170 0 C, for the indicated period that includes a margin or safety range.
- the sterilization process - without flames, without fire, without combustion - solid wastes release the liquid phase, in the form of condensable and non-condensable vapors, which are also sterilized during the process of formation and circulation within the chamber.
- Vapors receive more than 99% sterilization in the initial vaporization and circulation phase and, before being discharged into the environment, receive a triple chemical-mechanical selective filtration, of very high filtering power, through a cascade sequence of three special filters recommended by the EPA (Environment Protection Agency).
- the microbiological laboratory tests certify the degree or percentage of mortality or sterilization in the treated waste.
- the necessary heat for the process Io generate solar thermal collectors concentrators.
- OPERATION The hospital bioinfectious wastes are taken, loaded and introduced to HSEDBH, at any time between 18 hours and 9 hours the next day, that is during the night and the next morning according to the planning of the user hospital.
- a reflector concentrator system channels the direct solar radiation to a transparent cover of several glasses and increases the internal temperature of the sterilization chamber from initial 20-25 ° C until the final 160 - 170 0 C, or even until 180 - 200 0 C.
- the waste remains in the corresponding closed containers for a minimum of 2 days and a maximum of 5 days, for a total number of 6 hours, at least, at temperatures above the sterilization threshold (T> 135 0 C ).
- the heat transferred to the sterilization chamber passes to the containers and from there to the solid waste.
- the solid waste emits vapors that are filtered through a series of high power filters recommended by the EPA and finally out to the external environment.
