It relates to a differential pressure type atomizer capable of spraying with a vacuum cleaner, a spray unit including the same, and a microplastic dispersion generator including the spray unit.
최근 전세계적으로 플라스틱 누적 폐기물의 양이 증가하고 있으며, 많은 양의 플라스틱이 회수되지 않고 해양 등으로 유입되어 플라스틱에 의한 환경 오염이 심각해지고 있다. 특히 미세플라스틱은 생물 및 생태계에 심각한 영향을 주고 있으며, 다양한 동물의 서식지를 훼손 및 파괴하고, 인체에도 악영향을 주고 있다.Recently, the amount of accumulated plastic waste is increasing worldwide, and a large amount of plastic is not recovered but flows into the ocean, and the environmental pollution caused by plastics is getting serious. In particular, microplastics have a serious impact on living things and ecosystems, damage and destroy habitats of various animals, and adversely affect the human body.
미세플라스틱은 5mm이하의 작은 플라스틱 입자를 가리키는 말로 생성 기원에 따라 1차 미세플라스틱 및 2차 미세플라스틱으로 구분되며, 크기에 따라 미세플라스틱과 초미세플라스틱으로 구분될 수 있다. 이중 초미세플라스틱은 풍화에 의해 나노미터 수준으로 깨진 플라스틱으로, 공기 중에 부유된 초미세플라스틱은 나노에어로졸 상태로 인체에 흡입되어 축적되는 것으로 알려져 있다.Microplastic refers to small plastic particles of 5 mm or less, and is divided into primary microplastics and secondary microplastics according to the origin, and can be divided into microplastics and microplastics according to their size. Among them, microplastics are plastics broken down to nanometer level by weathering, and microplastics suspended in the air are known to be inhaled and accumulated in the human body in the form of nano-aerosols.
미세플라스틱의 발생원은 매우 다양하다. 예를 들어, 공업용 연마재, 화장품 또는 샌드 블라스트용 연마재 등에 직접 사용하기 위해서 생산되는 미세플라스틱이 있고, 다양한 제품을 생산하기 위한 전단계의 원료(펠렛)로 간접적으로 사용하기 위해서 생산되는 미세플라스틱(1차 미세플라스틱)이 있다. 그리고 해양 쓰레기 등의 큰 플라스틱 재료가 깨져서 환경 중에 형성된 미세플라스틱(2차 미세플라스틱)이 있다. 이러한 2차 미세플라스틱을 초래하는 원인은 물결 등의 기계적인 힘과 태양광, 특히 자외선이 일으키는 광화학적 프로세스로 알려져 있다. 또한 의류를 세탁하는 과정에서 천으로부터 합성섬유가 분리되어 발생하는 미세플라스틱이 있다.There are many different sources of microplastics. For example, there are microplastics produced for direct use in industrial abrasives, cosmetics, or abrasives for sandblasting, and microplastics produced for indirect use as raw materials (pellets) in the previous stage to produce various products (primary microplastics). There is also microplastics (secondary microplastics) formed in the environment by breaking large plastic materials such as marine debris. The cause of these secondary microplastics is known as a photochemical process caused by mechanical forces such as waves and sunlight, especially ultraviolet rays. There are also microplastics that are generated by the separation of synthetic fibers from fabrics in the process of washing clothes.
미세플라스틱에 의한 환경 오염이 심각해지면서 전세계적으로 체계적인 연구 및 법률 제정의 필요성이 대두되고 있다. 그러나 이를 위해서는 먼저 미세플라스틱에 대한 정확한 유해성 평가가 선행되어야 한다.As the environmental pollution caused by microplastics is getting serious, the need for systematic research and enactment of laws is emerging around the world.

And most of the currently known microplastic exposure standards are scientifically and experimentally unverified information.

The controller 184 may control the ultrasonic generator 118 to variously change the intensity of the ultrasonic wave generated by the ultrasonic generator 118 . The size of microplastics generated from plastic particles may be variously changed according to the intensity of ultrasonic waves applied to the solution (S). For example, if the intensity of the ultrasonic wave is increased, plastic particles having a relatively small size may be generated, and if the intensity of the ultrasonic wave is decreased, relatively large plastic particles may be generated.

Therefore, the user can adjust the distance the end of the movable rod 236 is spaced apart from the injection hole 155 by rotating the movable rod (236).
도 11의 (a)에 나타낸 것과 같이, 가동 로드(236)가 분사구(155)로부터 이격된 거리가 상대적으로 작으면 분사구(155)에서 분사되는 분무 입자가 더 많이 가동 로드(236)에 충돌하게 된다. 이 경우, 분무유닛은 상대적으로 크기가 작은 분무 입자를 분무할 수 있다.As shown in (a) of Figure 11, when the distance the movable rod 236 is spaced apart from the injection hole 155 is relatively small, the spray particles injected from the injection hole 155 more collide with the movable rod 236 do. In this case, the atomizing unit may atomize atomizing particles having a relatively small size.
반면, 도 11의 (b)에 나타낸 것과 같이, 가동 로드(236)가 분사구(155)로부터 이격된 거리가 상대적으로 크면 가동 로드(236)에 충돌하는 분무 입자의 양이 줄어들게 된다. 이 경우, 분무유닛은 상대적으로 크기가 큰 분무 입자를 분무할 수 있다.On the other hand, as shown in (b) of FIG. 11 , when the distance between the movable rod 236 and the injection hole 155 is relatively large, the amount of spray particles colliding with the movable rod 236 is reduced. In this case, the spray unit may spray relatively large-sized spray particles.
도 12 내지 도 13에 나타낸 분배기(240)는 분사관부(125)의 내측에 설치되는 분배기 플레이트(141)와, 분배기 플레이트(141)로부터 차압방식 분무기(150)의 분사구(155) 측으로 돌출되는 분배기 로드(241)를 포함한다. 분배기 플레이트(141)는 상술한 것과 같다.The distributor 240 shown in FIGS. 12 to 13 includes a distributor plate 141 installed inside the injection pipe part 125 and a distributor protruding from the distributor plate 141 to the injection port 155 side of the differential pressure sprayer 150 . and a rod 241 . The distributor plate 141 is the same as described above.
분배기 로드(241)는 그 중심이 차압방식 분무기(150)의 분사구(155) 중심과 일치하도록 배치된다. 분배기 로드(241)는 분사구(155)로부터의 이격 거리가 조절될 수 있도록 분배기 플레이트(141)에 결합된다. 즉 분배기 로드(241)는 분배기 플레이트(141)에 고정되는 고정 로드(242)와, 고정 로드(242)로부터 돌출될 수 있도록 고정 로드(242)에 이동 가능하게 결합되는 가동 로드(247)를 포함한다.The distributor rod 241 is arranged so that its center coincides with the center of the injection hole 155 of the differential pressure type atomizer 150 . The distributor rod 241 is coupled to the distributor plate 141 so that the separation distance from the injection hole 155 can be adjusted. That is, the distributor rod 241 includes a fixed rod 242 fixed to the distributor plate 141 and a movable rod 247 movably coupled to the fixed rod 242 so as to protrude from the fixed rod 242 . do.
고정 로드(242)의 내측에는 가동 로드(247)가 이동 가능하게 삽입되는 고정 로드 홈(243)이 마련된다. 또한 고정 로드(242)의 내측에는 가동 로드(247)를 선형 이동하도록 가이드하기 위한 가이드 돌기(244)가 구비된다. 도시된 것과 같이, 고정 로드(242)의 끝단은 분사구(155)에서 분사되는 기체 및 분무 입자의 흐름을 가능한 방해하지 않도록 곡면형으로 이루어질 수 있다.A fixed rod groove 243 into which the movable rod 247 is movably inserted is provided inside the fixed rod 242 . In addition, a guide projection 244 for guiding the movable rod 247 to linearly move is provided inside the fixed rod 242 . As shown, the end of the fixed rod 242 may be formed in a curved shape so as not to interfere with the flow of the gas and spray particles injected from the injection port 155 as much as possible.
가동 로드(247)는 고정 로드(242)로부터의 돌출 길이가 조절될 수 있도록 고정 로드 홈(243) 속에 삽입된다. 가동 로드(247)에는 가이드 돌기(244)에 대응하는 가이드 홈(248)이 가동 로드(247)의 이동 방향으로 따라 연장되도록 형성된다. 가동 로드(247)는 가이드 홈(248)에 가이드 돌기(244)가 삽입되도록 고정 로드(242)에 결합된다. 따라서 가동 로드(247)는 그 길이 방향으로 선형 이동할 수 있지만 고정 로드(242)에 대해 상대 회전할 수 없다.The movable rod 247 is inserted into the fixed rod groove 243 so that the protruding length from the fixed rod 242 can be adjusted. A guide groove 248 corresponding to the guide protrusion 244 is formed in the movable rod 247 to extend in the moving direction of the movable rod 247 . The movable rod 247 is coupled to the fixed rod 242 such that the guide protrusion 244 is inserted into the guide groove 248 . Thus, the movable rod 247 can move linearly in its longitudinal direction but cannot rotate relative to the stationary rod 242 .
가동 로드(247)의 선형 운동은 가동 로드 스토퍼(251)에 의해 일정 이동 간격으로 단속될 수 있다. 가동 로드 스토퍼(251)는 고정 로드(242)의 설치홈(245)에 설치되는 디텐트 돌기부재(252) 및 탄성부재(253)를 포함한다. 가동 로드(247)의 외면에는 디텐트 돌기부재(252)가 삽입될 수 있는 디텐트 홈(249)이 형성된다. 디텐트 홈(249)은 가동 로드(247)의 이동 방향을 따라 복수 개가 이격 배치된다. 디텐트 돌기부재(252)는 디텐트 홈(249)에 삽입될 수 있도록 고정 로드(242)의 설치홈(245) 속에서 이동할 수 있다. 탄성부재(253)는 디텐트 돌기부재(252)에 대해 디텐트 홈(249)에 삽입되는 방향으로 탄성력을 가한다.The linear motion of the movable rod 247 may be interrupted by the movable rod stopper 251 at regular movement intervals. The movable rod stopper 251 includes a detent protrusion member 252 and an elastic member 253 installed in the installation groove 245 of the fixed rod 242 . A detent groove 249 into which the detent protrusion member 252 can be inserted is formed on the outer surface of the movable rod 247 . A plurality of detent grooves 249 are spaced apart from each other along the moving direction of the movable rod 247 . The detent protrusion member 252 may move in the installation groove 245 of the fixing rod 242 so that it can be inserted into the detent groove 249 . The elastic member 253 applies an elastic force to the detent protrusion member 252 in a direction to be inserted into the detent groove 249 .
사용자가 가동 로드(247)를 이동시키는 중에 디텐트 돌기부재(252)가 디텐트 홈(249) 속에 삽입됨으로써 가동 로드(247)의 이동이 단속될 수 있다. 이와 같이 가동 로드 스토퍼(251)가 가동 로드(247)의 이동을 단속함으로써 사용자는 가동 로드(247)의 길이를 사전 설정된 길이만큼씩 다단으로 조절하는 것이 가능하다.While the user moves the movable rod 247 , the detent protrusion member 252 is inserted into the detent groove 249 so that the movement of the movable rod 247 may be intermittent. As such, the movable rod stopper 251 controls the movement of the movable rod 247 so that the user can adjust the length of the movable rod 247 in multiple stages by a preset length.
도 13의 (a)에 나타낸 것과 같이, 사용자가 가동 로드(247)를 분사구(155)에 상대적으로 가까이 배치하면 분사구(155)에서 분사되는 분무 입자가 더 많이 가동 로드(247)에 충돌하게 된다. 이 경우, 분무유닛은 상대적으로 크기가 작은 분무 입자를 분무할 수 있다.As shown in (a) of Figure 13, when the user arranges the movable rod 247 relatively close to the injection hole 155, the spray particles injected from the injection hole 155 collide with the movable rod 247 more. . In this case, the atomizing unit may atomize atomizing particles having a relatively small size.
반면, 도 13의 (b)에 나타낸 것과 같이, 사용자가 가동 로드(247)를 분사구(155)로부터 상대적으로 멀리 배치하면 가동 로드(247)에 충돌하는 분무 입자의 양이 줄어들게 된다. 이 경우, 분무유닛은 상대적으로 크기가 큰 분무 입자를 분무할 수 있다.On the other hand, as shown in (b) of FIG. 13 , when the user arranges the movable rod 247 relatively far from the injection hole 155 , the amount of spray particles colliding with the movable rod 247 is reduced. In this case, the spray unit may spray relatively large-sized spray particles.
본 실시예에서 가동 로드 스토퍼(251)의 구조는 다양하게 변경 가능하다. 즉 디텐트 돌기부재(252)의 구체적인 형상이나, 개수, 설치 위치 등은 다양하게 변경될 수 있다. 그리고 도면에는 가동 로드 스토퍼(251)가 고정 로드(242)에 설치되는 것으로 나타냈으나, 디텐트 홈(249)이 고정 로드(242)에 마련되고 가동 로드 스토퍼(251)가 가동 로드(247)에 설치되는 것도 가능하다.The structure of the movable rod stopper 251 in this embodiment can be variously changed. That is, the specific shape, number, and installation position of the detent protrusion member 252 may be variously changed. And in the drawing, it is shown that the movable rod stopper 251 is installed on the fixed rod 242, but a detent groove 249 is provided on the fixed rod 242 and the movable rod stopper 251 is installed on the movable rod 247. It can also be installed in
