Get back to Fig. 3, the rubbish 28 in the canister 26 comprises many thermoplastics from projects such as syringes usually.These materials will melt in the heating steps of processing procedure.In case hardening, the thermoplastic of these fusings will become nontoxic blocks, and the sharp edges of transfusion device, pipe, pin and point are all wrapped in the resin.Therefore medical waste 28 becomes and can not recognize maybe and can not be reused that sterilization is up to heating and hardening process.Rubbish 28 also may comprise the material and the soft refuse of non-thermal plasticity.This rubbish sterilization is given in heating, and they can be handled with common rubbish.

The following describes the advantage and the function of pipe 30.Work as medical waste, or any refuse of being made up of multiple material is when being heated, this material can not be heated in an orderly manner.Heating causes the gentle volume expansion problem of uncertain heating that is associated sometimes in the time of the material of this heterogeneity.This problem is handled in the utility model special consideration when design.

A ventilating opening 27 is arranged on the canister 26, allow gas to pine for flowing out canister 26 adding.Gas is initial because predetermined air flow flows to filter 38, the space in No. three chamber 24 around the rapid then filling containers 26.When No. three chamber 24 was filled, gas entered pipe 30.Pipe 30 provides extra safe space for the gas of discharging from container 26.Pipe 30 makes system 10 have the ability of processing to inconsistent this problem of heating of specific medical waste.Different thermal conductivitys, the different degassing and from the irregular reaction of irregular clinical waste that is associated and uneven heating can cause sometimes that uncertain gas expands to discharge from container 26.There is sufficient capacity that the contradiction of this gas stream, the safe space that provides gas to expand are provided in the pipe 30.

Opening 32 can link to each other with an air vessel or other additional gas savings device, and unnecessary gas can be stored up to being discharged by system in this device.An advantage of air vessel or pipe is to have eliminated the demand that is necessary to handle No. three bigger chamber 24 of emission Volume Changes to.Thereby only need less heat to heat the spatial domain around the container 26 in No. three chamber 24.

In operation, when container 26 is heated, clinical waste 28 unbalanced being heated.In refuse 28, the refuse of some bags of different densities is arranged, heat with different speed in the different time.Such as, have one bag of alcohol to be heated in the rubbish 28 and since the low boiling of alcohol it will than around the more Zao discharging waste gas that begins of material.This can produce fast and the gas flow of large volume, and this gas flow can cause dangerous air and communicable microorganism escapes from from 24 tops, No. three chamber or too quickly by dissipating behind the filter or being collected.In order to hold accident increase, specially be provided with pipe 30 in the equipment 10 from the air-flow of container 26.

In a first-selected model of the utility model 10, filter 38 is two stage charcoal type filters.Gas at first enters the antibiotic/antiviral microorganism and the biological part 39 of filter 38, the charcoal part 43 of passing through filter 38 then.In order to make the charcoal type filter carry out thoroughly effectively filtering to emission, any when needing the thing that filters through charcoal speed want slow so that charcoal is caught and is absorbed smell.Alcohol is a kind of material that often has in the medical waste, and its boiling point is very low.When alcohol has gasified in running of the present utility model, if filter cool it will be concentrated on the filter.Therefore the temperature of filter should remain on the level of the set point that is higher than alcohol, condenses on the filter to avoid alcohol.Born affinity is arranged between alcohol and the charcoal, and this alcohol that will cause concentrating again covers around the charcoal, stops charcoal to absorb smell.In order to keep filter temperature and prevention alcohol to condense, some heats of No. three chamber 24 generations are allowed to radiation and return filter 38.This realizes by allowing radiant heat from No. three chamber to pass inner casing 25 hot filtration apparatus tubes 38, also realizes by the flowing of cooling air around the restriction filter 38.Various insulating materials can be installed on the inner casing 25, and insulation keeps an acceptable temperature when making the equipment operation.

In any refuse load virus and bacterium are arranged all, they can just be gone out by air borne before temperature arrives the temperature that can kill them.The application of the material of anti-virus/antibiotic and position by trap all airborne viruses and bacterium eliminated this may.

Waste gas is along a predetermined and controlled direction process gas communication and tapping equipment 50.Gas communication and tapping equipment 50 are stayed hazardous gas and communicable microorganism in No. three chamber 24, pipe 34 and the filter 38.Like this by require waste gas before arriving gas communication and tapping equipment 50 through filter 38, filter 38 can be traped airborne bacterium and virus when just having guaranteed that air-flow is in this equipment.

In Fig. 2,5 and 6, can see the characteristics of gas communication and tapping equipment 50 easilier.Fig. 5 has represented that gas communication device 50 is a pair of fans that are positioned at this equipment 10 back sides 60 in first-selected model, 50a and 50b.No. one fan 50a is used for cooling off outside frame 14, and the negative pressure of air and airflow passes filter 38 is provided simultaneously.Fan 50a is at equipment continuous service between the operating period, and its flow velocity is preferably 15-25c.f.m., and this can produce an enough slow air-flow fully works filter.Too high flow velocity is unfavorable for the abundant filtration of medical waste, because pollutant can not stop time enough to be absorbed in filter.Therefore, the potential time of pollutant in filter 38 is long more, and the efficient of filter process pollutant and ability are strong more.No. two fan 50b are used for introducing the air of outside, No. three chamber 24 of cooling after heating cycle.This fan preferably turns round with the flow velocity of 25-35c.f.m..

On Fig. 6, can see three strands of tangible in check air-flows are arranged in the utility model 10.An air-flow 52 has comprised most of air of the system that flows through.No. one fan 50a has attracted from equipment 10 air outside by pressure control ventilating opening 48.The air-flow 52 of No. one chamber control is introduced into chamber 18 No. one through opening 48, flows towards gas circulation device 50.Similarly, gas communication device 50a produces negative pressure at the top of container 26 and equipment 10, through filter 38.The air-flow 52 of negative pressure 54 and No. one chamber control converges the gas communication at 56 places that flow through and tapping equipment 50.This air-flow 52 predetermined, No. one chamber control has guaranteed that the working environment around the equipment 10 exempts from the microorganism and the dangerous discarded invasion and attack of discharging when heating from container 26.

In garbage disposal and cooling period, the air-flow 52 of No. one chamber control has multi-functional.The air-flow 52 of No. one chamber control is produced by the fan 50a that is arranged in high pressure 62.High pressure 62 is intact parts in the system, and it is one and encases fan 50, the framework that it and filter same chambers 18 38 are kept apart.Flow through the air-flow of high pressure 62 from two sources.Air-flow most be the air-flow 52 of No. one chamber control, its is through near a series of big pressure control air vent 64 placing outward of being positioned at high pressure 62, the ventilation fan mouth.The air-flow 52 of No. one a large amount of chamber control mixes with the air through charcoal filter, to prevent the dangerous situation of high alcohol concentration.Remaining gas through high pressure 62 is representational minimum part, and it is derived from purifying gas flow discussed below.

Second function of the air-flow 52 of No. one chamber control is to make outside frame 14 remain on an acceptable temperature.In addition, filter 38 is placed in the air-flow high pressure 62, extremely contiguous internal rack 20.Thereby some handle the temperature that has improved it in heats advance high pressure by radiation the cavity 66.This evaporates the coagulation in the previous processing once again, avoided the back the processing stage on filter 38, condense.

No. two air-flows 90 of native system are purifying gas flows.So definition is chamber 24 because this strand air is flowed through No. three, passes through filter 38 then.Purifying gas flow 90 passes through charcoal filter 38 again through a big blast pipe at equipment top, imports the primary air in the high pressure 62 then, discharges from exhaust outlet 56 at last.

Purify air 90 from the inlet 35---just air vessel opening---that purifies air enter No. three chamber 24 and sweep across No. three chamber 24 inner canister 26 from bottom to top and internal rack 20 between the space, to guarantee the covering that has one deck pure air to form around the container 26.This layer around the container 26 pulls together to provide an additional function by purify air 90 coverings that form and air vessel 30, promptly absorbs the degassing pressure pulse that any explosion by the material that seethes with excitement causes.Purifying gas flow 90 is taken on means of transport, and degassing product is taken to filter 38 from container 26 tops.The cleaning effect of purifying gas flow 90 has guaranteed to finish do not have residual smell in the equipment 10 of back in the medical waste processing procedure simultaneously.

90 amount is very little although purify air, and it is more much bigger than the amount of degassing product.This has guaranteed that the degassing arrives filter 38 and avoided the degassing to assemble on container 26.Therefore, some have high-volatile medical waste item, as alcohol, understand some and condense on the filter 38 behind initial heating evaporation, have risen warm filter 38 then and with the synergy that has risen warm purifying gas flow 90 it have been evaporated once again.The cleaned air that is high concentration equally filters steam, has eliminated the peculiar smell in the processing procedure.

No. three air-flows in the utility model 10 are cooling blasts 96, shown in Fig. 6,7,8.No. two fan 50b imports No. two chamber 22 by pipe 97 with outside air 94, forms cooling blast 96.Cooling blast 96 finishes back cooling No. two chamber 22, internal rack 20 and inner casing 25 a heating cycle, discharge from exhaust outlet 98 as waste gas opening 99 backs of inner casing 25 bottoms of flowing through.
