At present, the processing mode of medical waste has burning and methods such as sterilization, sterilization in the world.The processing mode of China's medical waste mainly is to burn, adopt the burning mode to handle medical waste and produce secondary pollution unavoidably, especially burn plastic garbage and be easy to generate extremely toxic substance " dioxin " simultaneously, owing to consider hazardness and the environmental protection requirement of medical waste, the operating cost that the cost of investment of general curative refuse treatment plant and medical waste are handled is all very high.

Existing ethylene oxide sterilizing equipment mainly is that sterilization is used to medical device product, every cover oxirane sterilizing installation all is to have only a cabinet, often need deliver to preheating chamber to the product preheating before sterilization, delivers to Resolution Room after the sterilization and resolves, not only waste time and energy, also increased sterilising cycle; Especially at present can carry out the recycling of oxirane medicament without any ethylene oxide sterilizing equipment, after each sterilization finishes, all to be discharged into the oxirane medicament in the earth or the atmosphere, oxirane is poisonous, explosive dangerous materials, therefore, the discharging of oxirane not only pollutes and is dangerous, but also waste, the sterilization cost is improved, higher cost can be accepted for the medical device product sterilization of giving high value, but the article that become medical waste after using for these medical apparatus and instruments are sterilized, and cost factor is just extremely important, and having only cheaply, medical waste sterilizing equipment just has practicality.This utility model can carry out the recycling of oxirane medicament, reduced the sterilization cost of ethylene oxide sterilizing equipment widely, be particularly useful for medical waste is carried out sterilization treatment, particularly being not easy to burn or burn the medical waste article that are easy to generate secondary pollution (such as metallic article, glass, plastic etc.) at those, to carry out sterilization treatment more practical.Use this utility model to carry out sterilization treatment to medical waste, its investment and operation cost are all handled medical waste far below the burning mode, and, medical waste is carried out sterilization treatment, not only can effectively eliminate the harm of medical waste pathogenic bacteria, make the secondary utilization of some medical wastes become possibility again, therefore, have practicality; In addition, the cabinet of at present all ethylene oxide sterilizing equipments all is to be made of an independent body, the equipment that is particularly useful for the medical waste sterilization all needs to use equipment of large epoxy ethane sterilizing, its volume can reach tens and tens cubic metres, weight reaches tens tons, and the loading and unloading of equipment, transportation and installation are all very difficult like this.Simultaneously, owing to the difference that amount of sterilization is required, need the sterilizing installation of different size, the ethylene oxide sterilizing equipment of existing different size, every kind of specification all needs to manufacture and design separately, has also increased the manufacturing cost of equipment.This utility model adopts the combination type cabinet, so just only needs to increase or the quantity of minimizing assembly can realize different demands to cabinet volume size specification, has reduced the manufacturing cost of equipment.And be convenient to loading and unloading, transport and install.

Summary of the invention:

In order to increase a kind of new medical waste processing mode, this utility model provides a kind of can independently finish preheating, sterilization and parsing, especially can carry out recycling medical waste sterilizing equipment to the circulation of ethylene oxide sterilizing medicament, and this medical waste sterilizing equipment has adopted unprecedented cabinet compound mode.

The technical scheme that its technical problem that solves this utility model adopts is:

Every cover sterilizing installation adopts two cabinets, and when operate as normal, a cabinet is as medical waste sterilization use, another cabinet just can be used as preheating chamber and Resolution Room uses, the role of two cabinets can exchange at any time, and like this, the preheating of sterilizing article, sterilization and parsing are all carried out at a cabinet, or else need to carry repeatedly and put, time saving and energy saving, especially even more important for sterilizing to medical waste, because, medical waste has a large amount of virus, pathogenic bacteria, and it is very big repeatedly to carry hidden danger.Simultaneously, the design of two cabinets can realize the recycling of oxirane, method is to be provided with an oxirane displacement apparatus between two cabinets, realize the exchange of two cabinet oxirane medicaments by this displacement apparatus, the oxirane circulation is utilized, core technology in this oxirane displacement apparatus is that several oxirane Dialysis tubings are arranged, oxirane is realized displacement by these Dialysis tubings, Dialysis tubing can intercept air by ethylene oxide gas, the D-loop oxidative ethane be that principle is to be exactly the through characteristic of utilizing oxirane: oxirane is because its vapour pressure height, can reach 141Kp at 30 ℃, can penetrate north material easily, paper, packaging material such as carton, therefore, being widely used in sterilization of medical instrument uses.Experimental results show that: when oxirane metering is 800mg/L, pressure-when 15Kp is above, penetrated packaging material such as 50 layers of cotton, 50 layers of polyethylene thin film, 50 polyvinyl chloride films in 8 hours.Several oxirane Dialysis tubings are arranged in oxirane displacement apparatus of the present utility model, these Dialysis tubings adopt cylinder design, the internal layer of each Dialysis tubing is the stainless steel tube that the screen cloth eye is arranged, can ventilate smoothly, outer parcel dialyzer (as dialyzing paper or preservative film etc.) is carrying out oxirane when recycling, uniform temperature (30 ℃～60 ℃) and pressure (5～-40Kp) under, oxirane can pass dialyzer and mesh easily, and air is intercepted by dialyzer.Dialysis tubing adopts the cylinder design that mesh is arranged, and both can enlarge the dialysis area, the replacing velocity of intensifier ring oxidative ethane, and resistance to compression is again avoided because pressure reduction damages dialyzer.These Dialysis tubings all are sealed in the circular cylindrical cavity, certain space is arranged between these circular cylindrical cavities and the Dialysis tubing, form the outer cavity space of Dialysis tubing, this outer cavity space is connected by the QI KOU that displaces of pipeline with two sterilization cabinets, and the inner chamber of Dialysis tubing is connected with the displacement air inlet of two cabinets respectively, when the oxirane medicament is replaced, oxirane flows to from outside to inside on Dialysis tubing, the internal layer of Dialysis tubing is the stainless steel tube that mesh is arranged, and just can not pressed off, crush with regard to dialyzer like this.The displacement of two cabinets is advanced, the gas outlet all is to be controlled by pneumatic switch, when the D-loop oxidative ethane, after a sterilization cabinet (such as the A cabinet) sterilization finishes, another sterilization cabinet (B cabinet) also preheating has finished to change over to the preparation sterilizing works, at this moment, elder generation finds time to the B cabinet that preparation changes sterilizing works over to, generally be extracted into-40Kp about, after finding time to finish, open the pneumatic switch that the A cabinet displaces QI KOU and B cabinet displacement air inlet simultaneously, like this, the sterilizing gas of A cabinet enters (mainly being made up of ethylene oxide gas and air) in the circular cylindrical cavity (Dialysis tubing external cavity) of oxirane displacement apparatus, at this moment since the pressure of A cabinet 0～-5Kp about, with circular cylindrical cavity (Dialysis tubing external cavity) pressure in the oxirane displacement apparatus of its UNICOM also should 0～-5Kp about, simultaneously, since at this moment B cabinet pressure be evacuated to-40Kp about, so, the Dialysis tubing inside cavity pressure of connecting UNICOM with the air inlet of B cabinet also is-40Kp about, like this Dialysis tubing in, outside just have the pressure reduction about high outside and low outside-40Kp, under the effect of this pressure reduction, make the sterilizing gas in the A cabinet flow to the B cabinet, at this moment the sterilizing gas main component of this flow direction is the mist of air and oxirane, after this mist flows to the oxirane device for interchanging, air is blocked by the dialyzer of Dialysis tubing, enters in the B cabinet and oxirane can penetrate dialyzer.In replacement process, the air inlet of A cabinet will be connected with outside atmosphere, can remain the pressure reduction that A cabinet air pressure is higher than B cabinet air pressure like this.Pressure reduction between oxirane when beginning displacement two cabinets is about 40Kp, along with oxirane by the displacement of a cabinet to another cabinet, the pressure reduction of two cabinets will reduce gradually, when the B cabinet pressure that is advanced oxirane by displacement reach-15Kp～-finish displacement during the 10Kp left and right sides, and begin the B cabinet is poured pure ethylene oxide gas, make it the cabinet internal pressure to reach-normal sterilization pressure between 5Kp～0Kp, loss that like this can the complementary ring oxidative ethane, guarantee the concentration of ethylene oxide sterilizing medicament, guarantee sterilization effect.Like this, realized the displacement of oxirane medicament from the A cabinet to the B cabinet, it is recycling that the oxirane medicament is obtained.Equally, the B cabinet also is like this to the oxirane displacement of A cabinet;

Sterilization cabinet of the present utility model is to be grouped into by forward and backward door section and intermediate body portion, forward and backward door section size specification unanimity, intermediate can be that the identical split of several size specifications is formed, these parts are when forming cabinet, between each part the sealing strip strict seal to be arranged, like this, the cabinet after being assembled into is identical with the cabinet of independent body.When the cabinet of demand different volumes specification, just can realize as long as increase or reduce the quantity of intermediate split.For example, the volume of door and intermediate all was 2 cubic metres before and after we designed, when needing 4 cubic metres medical waste sterilization cabinet, door butt joint in front and back is got final product, add an intermediate in the middle of when needing 6 cubic metres medical waste sterilization cabinet, need 8 cubic metres two intermediate that add, can form any medical waste sterilizing equipment that needs the volume size by that analogy.
