Abstract

병원성 폐기물을 효과적으로 살균처리하는 일반적인 방법은 마이크로파 또는 고온의 압력증기를 이용하는 것이다. 마이크로파에 의한 방법은 간편하고 연속적 살균처리가 가능하지만 살균효과가 폐기물의 수분함유량에 의존적인 반면, 압력증기에 의한 방법은 살균효과가 균일하지만 폐기물의 연속적인 출입에 대한 증기압력 유지가 어려워 보통 AUTOCLAVE 형태로 적용되고 있다.

본 발명은 분쇄장치에 의해 분쇄된 후, 압력 유지 구조를 가진 회전식 입출력 장치에 의하여 연속적으로 공급되는 병원성 폐기물을 고온의 압력증기와 마이크로파를 복합적으로 이용하여 살균처리함으로써 처리효율 및 살균효과를 증대시킨다.

마이크로파, 증기, 연속식 살균장치

A common way to effectively sterilize pathogenic waste is through microwave or hot steam. While the method by microwave is simple and continuous sterilization is possible, the sterilization effect is dependent on the water content of the waste, while the method by pressure steam is uniform, but it is difficult to maintain the steam pressure for continuous access of the waste. It is applied in the form.

The present invention increases the treatment efficiency and sterilization effect by sterilizing pathogenic waste continuously supplied by a rotary input / output device having a pressure maintaining structure after being pulverized by a pulverizing apparatus using a combination of high temperature pressure steam and microwave. .

본 발명의 목적은 회전식 입출력 장치를 통해 연속적으로 공급되는 병원성 폐기물의 살균처리를 위한, 분쇄기가 부착된 마이크로파 및 압력증기를 이용한 연속식 살균 처리장치의 개발이다. 본 발명은 소형이며 연속식으로 작동되고, 분쇄기가 부착되어 각 병원에서 배출되는 병원성 폐기물을 자체처리 가능한 살균 처리장치이며, 마이크로파와 압력증기를 복합적으로 이용하여 살균효율을 높이는 장치이다.An object of the present invention is the development of a continuous sterilization apparatus using a microwave and pressure steam with a crusher for sterilization of pathogenic waste that is continuously supplied through a rotary input and output device. The present invention is a compact and continuous operation, a sterilization treatment apparatus capable of self-treatment of pathogenic waste discharged from each hospital with a crusher attached, it is a device to increase the sterilization efficiency by using a combination of microwave and pressure steam.

병원에서 배출되는 감염성 폐기물을 처리하기 위한 많은 방법과 다양한 장치들이 개발되어 왔다. 폐기물을 살균 처리하는 방법 중 가장 효율적인 것은 마이크 로파 또는 압력증기를 이용하는 것이다.Many methods and various devices have been developed for treating infectious waste discharged from hospitals. The most efficient way to disinfect waste is through microwave or pressure steam.

마이크로파는 대상물을 빠른 시간 내에 가열할 수 있으며, 전자기파에 의해 세포막을 파괴함으로써 폐기물을 살균할 수 있는 장점이 있다.Microwaves can heat objects quickly and have the advantage of sterilizing waste by breaking cell membranes by electromagnetic waves.

그러나, 마이크로파의 가열효과는 대상물의 유전특성에 의해 의존적이기 때문에 대상물의 종류에 따라 가열효율이 달라지며, 폐기물과 같이 여러가지 물질이 혼합되어 있는 경우에는 균일하게 살균되지 않는 문제점이 있다.However, since the heating effect of the microwave depends on the dielectric properties of the object, the heating efficiency varies according to the type of the object, and there is a problem in that it is not uniformly sterilized when various substances such as waste are mixed.

또한, 함수율이 낮을 경우 마이크로파가 흡수되지 않아 가열/살균효과가 저하된다.In addition, when the moisture content is low, microwaves are not absorbed, thereby lowering the heating / sterilization effect.

압력증기를 이용한 처리장치는 일정한 체적을 가진 압력용기에 증기발생기로부터 발생된 가열증기를 공급하여 압력용기 내부를 포화증기압 상태로 유지하는 것이다. 이로써 압력용기 내부의 압력은 대기압 보다 높게 형성되며, 온도 또한 물의 비등점 이상으로 유지하게 된다. 이러한 고압,고온을 일정시간 유지시킴으로써 폐기물의 종류 및 함수율에 관계없이 균일하게 처리가 가능하다.The treatment apparatus using pressure steam is to supply the heated steam generated from the steam generator to a pressure vessel having a constant volume to maintain the inside of the pressure vessel in a saturated steam pressure state. As a result, the pressure inside the pressure vessel is formed higher than atmospheric pressure, and the temperature is also maintained above the boiling point of water. By maintaining such high pressure and high temperature for a certain time, it is possible to treat uniformly regardless of waste type and water content.

그러나, 압력용기의 내부압력을 유지시키기 위해 일반적으로 autoclave방식의 비연속적 처리장치가 사용되어 왔으며, 폐기물이 연속적으로 출입하는 연속식 처리장 치의 경우는 내부압력의 유지가 용이하지 않다.However, in order to maintain the internal pressure of the pressure vessel, autoclave-type discontinuous treatment apparatuses have been generally used. In the case of continuous treatment apparatuses in which waste is continuously introduced, it is not easy to maintain the internal pressure.

짧은 시간에 대량의 폐기물을 처리하는 대형장치의 경우에는 처리용량 대비 출입구에서의 압력손실은 상대적으로 미미하여 연속식 처리방식을 적용하는 경우도 있다.In the case of large equipment that processes a large amount of waste in a short time, the pressure loss at the entrance to the treatment capacity is relatively small, and in some cases, continuous treatment is applied.

그러나, 소용량의 이동 가능한 자체 처리장치의 경우는 압력증기를 사용할 경우 비연속식이 일반적이며, 연속식의 경우는 구성이 복잡하고, 압력유지를 위한 과다한 에너지 소모 등의 문제가 있다.However, in the case of a small capacity mobile self-treatment apparatus, when using the steam is a non-continuous type, in the case of a continuous type, the configuration is complicated, there is a problem such as excessive energy consumption for maintaining pressure.

본 발명은 병원성 폐기물을 1차적으로 증기발생기를 통해 공급되는 대기압 이상의 압력과 비등점 이상의 온도를 가진 증기에 일정시간 이상 노출시켜 살균 처리한 후, 2차적으로 마이크로파에 의한 후처리 과정을 거침으로써 살균효율을 증가시킨다.According to the present invention, after sterilizing by exposing the pathogenic waste to steam having a temperature above the atmospheric pressure and boiling point which is supplied through the steam generator for a predetermined time or more, the sterilization efficiency is secondarily subjected to a post-treatment process by microwaves. To increase.

누설억제 구조를 가진 회전식 입출력장치를 이용하여 압력증기를 이용하면서도 폐기물의 연속적인 처리가 가능하고 분쇄기가 자체 부착되어 병원 자체처리가 가능하다.The rotary input / output device with a leak suppression structure enables the continuous treatment of waste while using pressure steam, and the crusher is attached to the hospital itself.

본 발명은 병원성 폐기물의 살균처리를 위해서 마이크로파 및 압력증기를 이용하여 살균 효율을 증대시키며, 회전식 입출력장치를 이용하여 연속적인 처리가 가능하며, 분쇄기가 자체 부착되어 병원 자체에서 처리 가능한 연속식 살균 처리장치이다.The present invention increases the sterilization efficiency by using microwave and pressure steam for sterilization of pathogenic waste, it is possible to continuously process using a rotary input and output device, continuous sterilization treatment that can be processed in the hospital itself with a grinder attached to itself Device.

증기압력 챔버(6)의 상부에는 회전식 입력장치와의 연결부(11)가 있고, 하부에는 회전식 출력장치와의 연결부(12)가 있다. 압력증기 챔버 내부는 2개의 컨베이어 벨트(14)로 구성되며 각각의 벨트에는 인장장치(15)가 있다. 분쇄된 폐기물의 원활한 흐름을 위해 와이퍼(16)가 설치되어 있으며, 최종 배출을 위해 깔대기(17)가 부착된다. 압력증기는 챔버 내부로 증기파이프(13)를 통해 공급된다.At the top of the vapor pressure chamber 6 there is a connection 11 with a rotary input device and at the bottom there is a connection 12 with a rotary output device. Inside the pressure steam chamber is composed of two conveyor belts 14, each of which has a tensioner 15. A wiper 16 is installed for smooth flow of the crushed waste, and a funnel 17 is attached for final discharge. Pressure steam is supplied through the steam pipe 13 into the chamber.

제3도는 회전식 입출력 장치의 상세 구성을 나타낸다.3 shows a detailed configuration of a rotary input / output device.

폐기물이 수거되고 배출되는 호퍼(18)와 압력증기 챔버와의 연결부인 어댑터(19)가 실린더 하우징(20)에 부착되어 있다. 실린더 하우징 내부는 디스크(22) 및 블레이드(23)가 접합된 축(24)이 삽입되어 있으며 디스크의 원주와 블레이드의 선단은 씰링처리 하기위해 홈가공이 되어 있다.An adapter 19, which is a connection between the hopper 18 and the pressure steam chamber where waste is collected and discharged, is attached to the cylinder housing 20. Inside the cylinder housing is inserted a shaft 24 to which the disk 22 and the blade 23 are joined, and the circumference of the disk and the tip of the blade are grooved for sealing.

호퍼(3)로 수거된 폐기물은 블레이드(2)에 의해 분쇄된 후 콜렉터(4)를 통해 회전식 입력장치(5)로 유입된다. 회전식 입력장치(5)의 축(24)은 외부 모터에 의해 일정한 속도로 회전하고 있으며 디스크(22)와 블레이드(23)이 형성하는 빈 체적에 폐기물이 쌓인다. 회전되는 폐기물은 압력증기 챔버(6) 내부로 자유낙하 하게 되며 컨베이어 벨트(14)위에 놓여진다. 외부 모터에 의해 미리 계산된 속도로 구동되는 컨베이어 벨트(14) 위에서 이송되어 지는 동안 폐기물은 증기파이프(13)를 통해 공급되는 대기압 이상의 압력증기에 노출된다. 이후 깔대기(17)를 통해 배출된 폐기물은 마이크로파 챔버(8)의 내부로 보내지며, 여기서도 폐기물을 이송하기 위한 별 도의 컨베이어 벨트가 있다. 벨트 위에서 이송되어 지는 동안 마그네트론(9)에 의해 발생되는 마이크로파로 추가 살균 처리된 후, 최종적으로 배출기(10)를 통해 배출된다.The waste collected by the hopper 3 is crushed by the blade 2 and then introduced into the rotary input device 5 through the collector 4. The shaft 24 of the rotary input device 5 is rotated at a constant speed by an external motor, and waste is accumulated in the empty volume formed by the disk 22 and the blade 23. The rotating waste free-falls into the pressure steam chamber 6 and is placed on the conveyor belt 14. The waste is exposed to pressure steam above atmospheric pressure supplied through the steam pipe 13 while being transported on the conveyor belt 14 driven at a predetermined speed by an external motor. The waste discharged through the funnel 17 is then sent to the interior of the microwave chamber 8, where there is a separate conveyor belt for conveying the waste. After being further sterilized by the microwaves generated by the magnetron 9 while being transported on the belt, it is finally discharged through the ejector 10.
