In carrying out the said procedure process, under heated condition, be conducive in treatment box, clinical waste be continued to stir.In the final stage of said procedure, repeat to absorb the clinical waste that gas is conducive to obtain dewatering state, thereby the pressure in the treatment box 2 is decreased near vacuum pressure.
Before carrying out this program, preferably the clinical waste of putting into treatment box is pulverized first.The unloading clinical waste stage preferably should carry out after treatment box is pressurized to atmospheric pressure again, then absorbs by 28 pairs of clinical wastes of aspirator.The present invention has some major advantages.In fact, device 1 has guaranteed clinical waste and the with it thorough sterilization of the gas of contact.It is sterilized that 200 degrees centigrade of heating-up temperature to quite high temperature have also guaranteed, especially after clinical waste was pulverized, heating process can penetrate more clinical waste and carry out.
Clean unit 5 has also guaranteed the sterilization of gas and contacting of unpasteurized clinical waste simultaneously, in addition, compares with the equipment that utilizes chemical/physical process or radiative process that clinical waste is sterilized, and the required energy of whole device still less.
In fact the required energy of great majority heating clinical waste is by the burning gained, rather than by electric power, should this also guarantee the lower operational cost of heating process.Another advantage that consists of is actually whole device and has guaranteed the sterilization of high speed high power capacity.
Treatment box 2 in fact can bear 300 kilogram weights, can carry out one time the sterilization cycle process in per 20 minutes.Namely per hour but amount of sterilization is greater than 600 kilograms, and amount of sterilization surpasses a larger autoclave.
In addition, the same with other bactericidal unit that utilizes high-pressure water vapor and microwave sterilizating, can not be subject to the impact of clinical waste kind to the sterilize length of required time of even clinical waste after crushed.
Another main advantage be clinical waste in fact with " bead " or block, drying shrinkage and the form of similar size discharge.Bead or block are not only light but also easily transmit, and this has finally also reduced the transmission cost.
Perhaps, this invention can make amendment in invention theory scope and change.For example, purifier may make into to replace general filter with an absolute filter, and full filter allows air to pass through, but does not allow passing through of the particle that pollutes or antibacterial and virus, and filter must regularly carry out disinfection or change.
Heating unit also can carry out other repacking, for example by using electric current or allowing the direct breakthrough process case 2 of heat, directly contacts clinical waste and heats, and also might carry out the repacking of other form simultaneously.Can be by like, the substituting of any form or size material carried out all these details repackings.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes description of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
