Description

싸이클론 집진장치 및 이를 이용한 집진방법Cyclone dust collecting device and dust collecting method using the same
본 발명은 기존 싸이클론과 비교하여 낮은 압력손실을 유지하면서도 집진효율을 개선할 수 있는 싸이클론 집진장치 및 이를 이용한 집진방법에 관한 것이다.The present invention relates to a cyclone dust collecting device and a dust collecting method using the same, which can improve the dust collection efficiency while maintaining a low pressure loss compared to a conventional cyclone.
싸이클론 집진장치는 기체-고체, 기체-액체, 액체-고체 분리장치의 한 종류이다. 예를 들어, 유체가 기체인 경우 싸이클론에 유입되는 기체에 선회류를 형성시키면 기체 속에 부유하고 있는 고체나 액체 상태의 입자상 물질에는 원심력이 작용하게 되고 이러한 원심력에 의해 입자상 물질이 제거된다. 통상의 싸이클론 집진장치의 구조는 도 1 에서 도시한 바와 같이, 하부에 저장탱크(130)와 이에 일체되어 수직방향으로 입설된 원통형의 본체(100)와, 상기 본체(100)의 상부 외벽에서 내부로 연통하도록 접선방향으로 수평 구성된 가스 유입구(110)와, 타 측에는 가스 유입구보다 상부에 위치하여 가스가 배출되는 배출구(120)로 마련된 구조를 갖는다.Cyclone dust collectors are a type of gas-solid, gas-liquid, and liquid-solid separators. For example, when the fluid is a gas, when a swirl flow is formed in a gas flowing into the cyclone, a centrifugal force acts on the solid or liquid particulate matter floating in the gas, and the particulate matter is removed by the centrifugal force. The structure of a conventional cyclone dust collector is shown in FIG. 1, in a storage tank 130 and a cylindrical body 100 integrally inserted therewith in the lower portion, and an upper outer wall of the body 100. It has a structure provided with a gas inlet 110 horizontally configured in a tangential direction to communicate with the inside, and an outlet 120 at which gas is discharged from the gas inlet on the other side.
가스 중의 입자상 물질을 제거하기 위한 집진장치로는 전기집진기, 여과집진기, 스크러버, 싸이클론 등이 주로 사용된다. 여기서 입자상 물질이라 함은 고체상 입자와 액체상 입자를 모두 포함하는 개념으로, 본 발명에서는 가스 중에 포함된 고체상 입자인 분진 제거에 초점을 맞추어 기술하고 있음을 미리 언급하고자 한다. 싸이클론 집진장치는 단순한 구조적 특성으로 인해 시설비용이 저렴하다는 장점이 있으나, 전기집진기나 여과집진기에 비해 집진효율이 낮고, 압력손실이 50 - 150mmAq 정도로 단독으로 사용될 경우에는 백필터에 비해 상대적으로 낮으나, 전기집진장치 또는 백필터의 전단에 1차 집진장치로서 적용될 경우에는 압력손실이 높아 운전비용을 상승시키는 요인이 된다. 또한 기존 싸이클론은 마모성이 높은 분진 제거에 적용될 경우 싸이클론 및 배관 등에 마모가 쉽게 발생하여 성능의 신뢰성과 운전 안정성 측면에서 취약성을 갖고 있다. 이러한 마모문제를 해결하기 위해 싸이클론 내벽을 세라믹 재질의 내마모재로 보강하는 방법 등이 적용되고 있으나 이로 인해 시설비용이 큰 폭으로 증가하게 된다. Electrostatic precipitators, filter precipitators, scrubbers, cyclones, and the like are mainly used as dust collectors for removing particulate matter in gases. Here, the term “particulate matter” is a concept including both solid and liquid particles, and the present invention focuses on removing dust, which is solid particles contained in a gas, and will be described in advance. Cyclone dust collector has the advantage of low facility cost due to its simple structural characteristics, but has low dust collection efficiency compared to an electrostatic precipitator or a filter dust collector, and is relatively low compared to a bag filter when used alone as a pressure loss of 50-150 mmAq. When applied as a primary dust collector to the front end of an electrostatic precipitator or bag filter, the pressure loss is high, which increases the operating cost. In addition, existing cyclones are easily vulnerable to cyclones and piping when applied to remove dust with high abrasion, and thus have vulnerabilities in terms of performance reliability and operational stability. In order to solve such a wear problem, a method of reinforcing the inner wall of the cyclone with a wear-resistant material of ceramic material has been applied, but this greatly increases the facility cost.
이러한 기존 싸이클론의 압력손실을 낮추고 마모에 따른 문제를 극복하기 위하여 한국등록특허 제1132320호에는 이중 외벽 구조를 갖고 내부 집진체에 슬릿을 형성하여 유입되는 일부 가스가 슬릿을 통과할 수 있도록 구성된 싸이클론 집진장치가 개시되어 있다. In order to lower the pressure loss of the existing cyclone and overcome the problems caused by abrasion, Korean Registered Patent No. 1132320 has a double outer wall structure and forms a slit in the internal dust collecting body so that some of the incoming gas can pass through the slit. A clone dust collector is disclosed.

In addition, Figure 5 shows a cross-sectional view of a cyclone dust collecting apparatus using a conventional slit-formed dust collector.
도 2 내지 도 5에 도시된 싸이클론 집진장치는 분진 발생원(90)으로부터 발생되는 함진 가스 내 분진을 제거하기 위한 것으로 집진체(10), 유입부(20), 집진하우징(30), 배출부(40), 로터리 밸브(50), 저장조(60), 제1 슬릿(14), 제2슬릿(15) 등을 포함하여 구성됨을 알 수 있다. The cyclone dust collector shown in FIGS. 2 to 5 is for removing dust in the impregnated gas generated from the dust generating source 90, and the dust collecting body 10, the inlet part 20, the dust collecting housing 30, and the discharge part It can be seen that it is configured to include 40, the rotary valve 50, the storage tank 60, the first slit 14, the second slit 15, and the like.
집진체(10)는 일정한 직경(D1)의 1차 집진부(11)와, 상기 1차 집진부(11) 하단에 연통되도록 연장 형성되며 하단방향으로 직경(D2)이 점차 줄어드는 2차 집진부(12)로 이루어지고, 유입부(20)는 1차 집진부(11)의 한 변에 접하는 방향으로 함진 가스가 유입되도록 한다. 또한, 집진 하우징(30)은 집진체(10)를 내부에 소정간격 이격시키거나 내접하도록 내설하게 되며, 배출부(40)는 집진 하우징(30)과 1차 집진부(11)의 일단에 일정한 깊이로 삽입 연통되어 분진이 제거된 가스가 외부로 배출되도록 한다. 로터리 밸브(50)는 집진 하우징(30)의 타단에 결합되고, 저장조(60)는 로터리 밸브(50)의 일단에 결합되어 상기 집진 하우징(30) 내에서 제거된 분진이 저장되게 된다. 제1슬릿(14)은 1차 집진부(11) 벽면에 길이방향으로 절개되고, 제2슬릿(15)은 2차 집진부(12) 벽면에 길이방향으로 절개되어 형성된다. 도 3과 도 4에서는 제1슬릿(14)과 제2슬릿(15)이 싸이클론 길이방향으로 동일한 위치에 형성된 예를 보여주고 있으나 제1슬릿(14)과 제2슬릿(15)의 길이방향 위치는 다르게 형성될 수 있다.The dust collecting body 10 is formed to extend to communicate with the primary dust collecting part 11 of a certain diameter (D1), and the primary dust collecting part 11, and the secondary dust collecting part 12 whose diameter D2 gradually decreases in the lower direction. It is made of, the inlet 20 is to allow the impregnated gas to flow in a direction in contact with one side of the primary dust collecting unit (11). In addition, the dust collecting housing 30 is installed to space or inscribe the dust collecting body 10 at a predetermined interval therein, and the discharge part 40 has a constant depth at one end of the dust collecting housing 30 and the primary dust collecting part 11. It is inserted into the furnace so that the gas from which the dust has been removed is discharged to the outside. The rotary valve 50 is coupled to the other end of the dust collecting housing 30, and the reservoir 60 is coupled to one end of the rotary valve 50 so that dust removed in the dust collecting housing 30 is stored. The first slits 14 are cut in the longitudinal direction on the wall surface of the primary dust collecting part 11, and the second slits 15 are formed in the longitudinal direction in the wall surface of the secondary dust collecting part 12. 3 and 4 show an example in which the first slits 14 and the second slits 15 are formed at the same position in the cyclone longitudinal direction, but the first slits 14 and the second slits 15 are in the longitudinal direction. The location can be formed differently.
따라서 도 2 내지 도 5에 도시된 싸이클론 집진장치는 유입부(20)를 통해 1차 집진부(11) 내로 유입된 함진 가스 내 분진 입자 중 관성력이 큰 분진 입자의 경우 원심력과 관성력에 의해서 집진체(10)의 벽면에 절개된 제 1슬릿(14) 또는 제 2슬릿(15) 중 하나를 통과하여 집진체(10)와 집진 하우징(30) 사이에서 제거되어 저장조(60)로 낙하되고, 관성력이 상대적으로 작은 분진 입자의 경우 원심력에 의해 집진체(10) 내에서 선회 유동하면서 저장조(60)로 낙하되며, 싸이클론에서 제거되지 못하는 매우 미세한 분진 입자는 처리가스와 함께 배출부(40)를 통해 배출되게 된다. Accordingly, the cyclone dust collector shown in FIGS. 2 to 5 is a dust particle having a high inertia force among dust particles in the impregnated gas flowing into the primary dust collecting part 11 through the inlet 20, the dust collecting body by centrifugal force and inertia force It is removed between the dust collecting body 10 and the dust collecting housing 30 through one of the first slits 14 or the second slits 15 cut into the wall surface of (10) and dropped into the storage tank 60, the inertia force In the case of these relatively small dust particles, the centrifugal force rotates in the dust collecting body 10 while falling into the storage tank 60, and very fine dust particles that cannot be removed from the cyclone are discharged 40 together with the processing gas. Is discharged through.
그러나, 이러한 종래 싸이클론 집진장치는 압력손실을 감소시킬 수는 있으나, 원심력과 관성력만으로는 집진효율을 증가시킬 수 없다는 단점이 여전히 존재한다. However, such a conventional cyclone dust collector can reduce the pressure loss, but still has the disadvantage that it cannot increase the dust collection efficiency only by centrifugal force and inertial force.
따라서 한국등록특허 제1132320호에 개시된 싸이클론 집진장치의 낮은 압력손실 특성을 유지하면서도 집진효율을 더욱 개선할 수 있는 싸이클론 집진장치가 요구된다Therefore, a cyclone dust collecting device capable of further improving dust collection efficiency while maintaining a low pressure loss characteristic of the cyclone dust collecting device disclosed in Korean Patent No. 1132320 is required.

따라서 본 발명은 상기와 같이 한국등록특허 제1132320호에 개시된 종래 싸이클론 집진장치의 문제점인 상대적으로 낮은 집진효율을 개선하고자 안출된 것으로서, 결과적으로 종래 슬릿이 형성된 집진체를 이용하여 싸이클론 집진장치의 구조 개선 및 집진 방법의 개선을 통해 장점인 낮은 압력손실(공기저항)을 유지하면서도 집진효율을 큰 폭으로 향상시킬 수 있는 싸이클론 집진장치 및 이를 이용한 집진방법을 제공하고자 한다.Accordingly, the present invention was devised to improve the relatively low dust collection efficiency, which is a problem of the conventional cyclone dust collector disclosed in Korean Patent No. 1132320, as a result, and as a result, a cyclone dust collector using a dust collector formed with a conventional slit. To provide a cyclone dust collecting device and a dust collecting method using the same, which can significantly improve the dust collection efficiency while maintaining a low pressure loss (air resistance), which is an advantage through improvement of the structure and improvement of the dust collection method.
보다 구체적으로 기술하자면, 종래 슬릿이 형성된 집진체를 이용한 싸이클론 집진장치는 유입되는 가스 중의 일부가 집진체 슬릿을 통과하여 빠져 나가기 때문에 집진체 내부의 선회유동이 약화됨으로써 싸이클론 집진장치의 압력손실이 낮아진다. 즉, 도 1에 도시한 통상의 싸이클론 집진장치는 본체(100) 내부에서 강한 선회류가 생성되고 이로 인한 원심력에 의해 분진이 제거되는 원리가 적용되며, 이때 압력손실은 싸이클론 내부의 강한 선회류로 인한 에너지 손실이 주 원인으로 작용한다. 반면 종래 슬릿이 형성된 집진체를 이용한 싸이클론 집진장치에서는 유입되는 전체 처리가스 중 일부가 슬릿으로 빠져나가기 때문에 집진체 내부에서 선회류를 형성하는 처리가스의 유량이 감소하고 따라서 선회류의 유속이 감소하기 때문에 압력손실이 낮아지게 되는 것이다. More specifically, the cyclone dust collector using a dust collector formed with a conventional slit has a pressure loss of the cyclone dust collector due to a weakening of the swirling flow inside the dust collector because some of the incoming gas passes through the dust collector slits. This is lowered. That is, in the conventional cyclone dust collector shown in FIG. 1, the principle that strong swirl flow is generated inside the main body 100 and dust is removed by centrifugal force is applied, and the pressure loss is a strong swing inside the cyclone. Energy loss due to current is the main cause. On the other hand, in the conventional cyclone dust collector using a slit-formed dust collector, a part of the entire processing gas flowing in is discharged into the slit, so that the flow rate of the processing gas forming a swirl flow inside the dust collector decreases, and thus the flow velocity of the swirl flow decreases. Therefore, the pressure loss is lowered.
반면, 집진효율 측면에서 종래의 슬릿이 형성된 집진체를 이용한 싸이클론 집진장치의 성능을 살펴보면, 슬릿(13)을 통과하여 집진체(10) 외면과 집진 하우징(30) 사이의 공간으로 유입되는 분진은 상당부분 관성력에 의해 제거되지만 집진체(10) 하단부로 재유입되어 배출부(40)를 통해 배출되는 분진의 양도 무시할 수 없다. 또한 집진체(10) 내부에서 선회류를 따라 이동하는 분진은, 약해진 선회유속으로 인해 분진에 작용하는 원심력도 약해지기 때문에 원심력에 의한 집진효율이 저하되는 특징이 있다. 결과적으로 종래의 슬릿이 형성된 집진체를 이용한 싸이클론 집진장치의 경우에는 압력손실 측면에서는 큰 장점이 있지만 집진효율 측면에서는 오히려 성능이 저하될 수 있다는 문제점이 있다.On the other hand, looking at the performance of the cyclone dust collector using a conventional slit-formed dust collector in terms of dust collection efficiency, dust that flows through the slit 13 into the space between the outer surface of the dust collector 10 and the dust collecting housing 30. Silver is removed by a considerable amount of inertia, but the amount of dust discharged through the discharge unit 40 after being re-introduced to the lower end of the dust collecting body 10 cannot be ignored. In addition, dust moving along the swirl flow inside the dust collecting body 10 has a characteristic in that the dust collection efficiency due to the centrifugal force is reduced because the centrifugal force acting on the dust is also weakened due to the weakened swirl flow velocity. As a result, in the case of a cyclone dust collector using a conventional slit-formed dust collector, there is a great advantage in terms of pressure loss, but there is a problem in that performance may be degraded in terms of dust collection efficiency.
따라서 본 발명에서는 종래의 슬릿이 형성된 집진체를 이용한 싸이클론 집진장치의 기본 구성을 기반으로 하여 낮은 압력손실이 유지되도록 하고, 집진효율의 개선을 위해 전기집진기술을 도입하고, 전기집진에 의한 효율 향상을 극대화할 수 있는 싸이클론 구성과 구조, 그리고 집진 방법을 개시하고자 한다. Therefore, in the present invention, based on the basic configuration of a cyclone dust collector using a conventional slit-formed dust collector, a low pressure loss is maintained, an electrostatic dust collection technology is introduced to improve the dust collection efficiency, and the efficiency by electrostatic dust collection. We would like to disclose a cyclone configuration, structure, and dust collection method that can maximize improvement.

이하에서는 본 발명의 실시예에 따른 싸이클론 집진장치(1)의 구성 및 기능에 대해 설명하도록 한다. 먼저, 도 6은 본 발명의 제1실시예에 따른 집진장치 구성과 집진원리를 나타내기 위한 싸이클론 집진장치(1)의 평단면도를 도시한 것이다. Hereinafter, the configuration and function of the cyclone dust collector 1 according to an embodiment of the present invention will be described. First, FIG. 6 shows a cross-sectional plan view of a cyclone dust collector 1 for showing the construction and dust collecting principle according to the first embodiment of the present invention.
도 6에 도시된 바와 같이, 본 발명에 따른 싸이클론 집진장치(1)는 앞서 본 발명의 배경이 되는 기술에서 언급하고 도 3과 도4에 도시한 슬릿(13)을 갖는 집진체(10)가 내장된 싸이클론 집진장치의 구성을 포함하면서, 동시에 전기집진 원리를 적용한 것임을 알 수 있다. As illustrated in FIG. 6, the cyclone dust collecting device 1 according to the present invention is referred to in the background technology of the present invention and has a slit 13 shown in FIGS. 3 and 4 and a dust collecting body 10. It can be seen that, while including the configuration of the cyclone dust collector built in, the principle of electrostatic dust collection was applied at the same time.
따라서 본 발명의 제1실시예에 따른 싸이클론 집진장치(1)는 슬릿(13)이 형성된 집진체(10)를 이용한 종래의 싸이클론 집진장치의 구성요소에 해당되는 집진체(10), 유입부(20), 집진 하우징(30), 배출부(40) 등을 포함하고, 이에 부가하여 전압인가부(70)를 포함하여 구성된다. Therefore, the cyclone dust collector 1 according to the first embodiment of the present invention is a dust collector 10 corresponding to a component of a conventional cyclone dust collector using a dust collector 10 in which a slit 13 is formed, inflow It includes a part 20, a dust collecting housing 30, a discharge part 40, and the like, and in addition, includes a voltage applying part 70.
집진체(10)는 내부공간을 갖고 벽면에는 길이방향으로 절개되는 단일개 또는 다수개의 슬릿(13)이 형성된다. The dust collecting body 10 has an internal space and a single or a plurality of slits 13 that are cut in the longitudinal direction are formed on the wall surface.
보다 구체적으로, 집진체(10)는 일정한 직경을 갖고 벽면에 길이방향으로 절개되는 단일개 또는 다수개의 제1슬릿(14)을 갖는 1차 집진부(11)와, 이러한 1차 집진부(11) 하단에 연통되도록 연장 형성되며 하단방향으로 직경이 점차 줄어드는 2차 집진부(12)를 포함하여 구성될 수 있다. 이때 2차 집진부는 벽면에 길이방향으로 절개되는 단일개 또는 다수개의 제2슬릿(15)이 형성될 수 있다. More specifically, the dust collecting body 10 has a certain diameter and a primary dust collecting part 11 having a single or multiple first slits 14 that are cut in the longitudinal direction on the wall surface, and the lower end of the primary dust collecting part 11 It may be configured to include a secondary dust collecting portion 12 is formed to extend to communicate with the diameter gradually decreases in the lower direction. At this time, the secondary dust collecting unit may be formed with a single or multiple second slits 15 that are cut in the longitudinal direction on the wall surface.
여기서, 제1 슬릿(14)과 제2 슬릿(15)은 연장되어 일체형으로 형성되지 않고 상호 분리되어 형성될 수 있으며, 집진체(10) 길이 방향으로 동일한 위치나 다른 위치에 형성될 수 있다.Here, the first slit 14 and the second slit 15 are extended and may not be integrally formed, but may be formed separately from each other, and may be formed at the same location or at different locations in the longitudinal direction of the dust collecting body 10.
또한, 1차 집진부(11)와 1차 집진부(11)에 마련된 제1 슬릿(14)은 길이가 가변되도록 마련될 수 있다. 더욱 상세하게는, 1차 집진부(11)는 2차 집진부(12) 대비 길이 비율이 증가하거나 감소하도록 마련될 수 있으며, 이에 대응하여, 제1 슬릿(14)도 제2 슬릿(15) 대비 길이 비율이 증가하거나 감소하도록 마련될 수 있다. 이처럼 1차 집진부(11)와 제1 슬릿(14)은 유입되는 분진의 종류, 크기 및 유입되는 함진 가스의 유속 등에 대응하여 길이가 가변되어 최적의 집진 효율을 내도록 할 수 있다.In addition, the first slit 14 provided in the primary dust collecting part 11 and the primary dust collecting part 11 may be provided to have a variable length. More specifically, the primary dust collecting part 11 may be provided to increase or decrease the length ratio compared to the secondary dust collecting part 12, and correspondingly, the first slits 14 also have a length compared to the second slits 15. Ratios can be provided to increase or decrease. In this way, the primary dust collecting part 11 and the first slit 14 are variable in length in response to the type and size of the incoming dust and the flow rate of the incoming gas, so that optimum dust collection efficiency can be obtained.
그리고, 1차 집진부(11)는 2차 집진부(12) 대비 길이가 길도록 마련됨이 바람직하다.And, the primary dust collecting part 11 is preferably provided to have a longer length than the secondary dust collecting part 12.
유입부(20)는 1차 집진부(11)의 한 변에 접하는 방향으로 함진 가스가 유입되도록 한다. 본 발명의 제1실시예에 따라 집진체(10) 내로 유입되는 함진가스에 포함된 분진은 전기적으로 대전된 분진인 경우 집진효율이 향상된다. 따라서 집진체(10) 내로 유입되기 전에 분진을 대전시키기 위한 다양한 수단 및 형태의 하전수단을 포함하여 구성되게 된다.The inlet portion 20 allows the impregnated gas to flow in a direction in contact with one side of the primary dust collecting portion 11. According to the first embodiment of the present invention, dust included in the dust gas flowing into the dust collecting body 10 is improved in the case where the dust is electrically charged dust. Therefore, it is configured to include various means and charging means in various forms for charging dust before it flows into the dust collecting body 10.
또한, 유입부(20)를 포함한 집진체(10)와 집진 하우징(30) 사이는 절연된 상태로 이루어질 수 있으며, 도시하지는 않았으나 본 발명에서 전위차가 발생하는 구성 요소간에는 반드시 절연이 되어야 한다. 즉, 집진체(10)와 배출부(40) 사이, 집진 하우징(30)과 배출부(40) 사이, 또는 집진체(10)와 집진 하우징(30) 사이에 전위차가 발생하도록 구성된 경우에 전기적으로 쌍을 이루는 각 구성요소 사이는 항상 절연된 상태를 유지하여야 한다.In addition, between the dust collecting body 10 including the inlet portion 20 and the dust collecting housing 30 may be formed in an insulated state, although not illustrated, it must be insulated between components generating a potential difference in the present invention. That is, when the electric shock is configured to generate a potential difference between the dust collecting body 10 and the discharge part 40, between the dust collecting housing 30 and the discharge part 40, or between the dust collecting body 10 and the dust collecting housing 30 Each pair of components must be kept insulated.
집진 하우징(30)은 집진체(10)를 내부에 소정간격 이격시키거나 내접하도록 내설하게 된다. 이러한 집진 하우징(30)은 원형, 타원형, 다수번 절곡되는 다각형의 단면 중 하나의 단면을 가질 수 있다. The dust collecting housing 30 is installed so that the dust collecting body 10 is spaced at a predetermined distance therein or inscribed therein. The dust collecting housing 30 may have one cross section of a circular, elliptical, polygonal cross section that is bent multiple times.
배출부(40)는 집진 하우징(30)과 집진체(10)에 일정한 깊이로 삽입 연통되어 분진이 제거된 가스가 외부로 배출되도록 한다. 그리고 로터리 밸브(50)는 집진 하우징(30)의 하단에 결합되며, 저장조(60)는 로터리 밸브(50)의 일단에 결합되어 집진 하우징(30) 내에서 제거된 분진이 저장되게 된다. The discharge part 40 is inserted into the dust collecting housing 30 and the dust collecting body 10 at a predetermined depth so that the gas from which dust is removed is discharged to the outside. And the rotary valve 50 is coupled to the lower end of the dust collecting housing 30, the storage tank 60 is coupled to one end of the rotary valve 50 to store the dust removed in the dust collecting housing 30.
이때, 배출부(40)는 집진체(10)에 일정 깊이로 삽입된 상태로 마련되기 때문에 교체가 용이하다.At this time, since the discharge portion 40 is provided in a state inserted into the dust collecting body 10 at a certain depth, it is easy to replace.
본 발명의 제1실시예에 따른 싸이클론 집진장치(1)는 전기 집진원리를 적용하기 위하여 배출부(40)와 집진 하우징(30) 사이에 전위차를 발생시켜 집진 하우징(30) 내부에 전기장을 형성시키게 된다. The cyclone dust collecting device 1 according to the first embodiment of the present invention generates an electric field inside the dust collecting housing 30 by generating a potential difference between the discharge part 40 and the dust collecting housing 30 to apply the electric dust collecting principle. Is formed.
즉, 전압인가부(70)는 배출부(40), 집진 하우징(30) 및 집진체(10) 중 적어도 어느 하나에 전압을 인가하여 집진 하우징(30) 내에 전기장을 형성하게 된다. That is, the voltage applying unit 70 forms an electric field in the dust collecting housing 30 by applying a voltage to at least one of the discharge part 40, the dust collecting housing 30 and the dust collecting body 10.
구체적으로 제1실시예에서, 전압인가부(70)는 집진체(10) 및 배출부(40) 중 어느 하나 이상에 전압을 인가하게 되고, 집진 하우징(30)은 접지시키게 된다. 예를 들어, 전압인가부(70)가 배출부(40)에만 전압을 인가하여 배출부(40)에 10kV의 전압을 인가하고 집진 하우징(30)을 접지시키게 되는 경우 배출부(40)와 집진 하우징(30) 사이에10kV의 전위차가 발생되게 된다. 만약 집진체(10)가 배출부(40)와 집진 하우징(30)에 대해 각각 전기적으로 절연되어 있다면 집진체(10)는 일정한 전위를 갖게 되고 집진체(10)와 배출부(40) 사이에는 전위차가 생성되며, 또한 집진체(10)와 집진 하우징(30) 사이에도 전위차가 발생하게 된다. 그러나 집진체(10)와 집진 하우징(30)이 전기적으로 연결되어 있다면 집진체(10)의 전위는 집진 하우징(30)의 전위와 동일하게 되어 집진체(10)와 집진 하우징(30) 사이에는 전위차가 없고 배출부(40)와 집진체(10) 또는 집진 하우징(30) 사이에만 전위차가 존재하게 된다.Specifically, in the first embodiment, the voltage applying unit 70 applies a voltage to any one or more of the dust collecting body 10 and the discharge part 40, and the dust collecting housing 30 is grounded. For example, when the voltage application unit 70 applies a voltage of 10 kV to the discharge unit 40 by applying a voltage only to the discharge unit 40 and the dust collecting housing 30 is grounded, the discharge unit 40 and the dust collection unit A potential difference of 10 kV is generated between the housings 30. If the dust collecting body 10 is electrically insulated from the discharge part 40 and the dust collecting housing 30, the dust collecting body 10 has a constant electric potential, and between the dust collecting body 10 and the discharge part 40, A potential difference is generated, and also a potential difference occurs between the dust collecting body 10 and the dust collecting housing 30. However, if the dust collecting body 10 and the dust collecting housing 30 are electrically connected, the electric potential of the dust collecting body 10 is the same as the electric potential of the dust collecting housing 30, so that between the dust collecting body 10 and the dust collecting housing 30, There is no potential difference and there is a potential difference only between the discharge portion 40 and the dust collecting body 10 or the dust collecting housing 30.
본 발명의 싸이클론 집진장치(1) 내에서 분진의 거동을 살펴보면, 집진체(10) 내로 유입된 함진 가스 내의 분진이 (-)로 대전되어 있고 배출부(40)에 (-)10kV가 인가되며 집진체(10)와 집진 하우징(30)은 접지되어 있다면, 대전된 분진과 배출부(40) 외면 사이에는 분진을 배출부(40) 외면으로부터 집진체(10) 내면 및 집진 하우징(30) 내면 방향으로 밀어내는 전기력이 발생되게 된다. Looking at the behavior of the dust in the cyclone dust collector (1) of the present invention, the dust in the impregnated gas flowing into the dust collector (10) is charged with (-), and (-) 10 kV is applied to the discharge part (40). If the dust collecting body 10 and the dust collecting housing 30 are grounded, dust is discharged between the charged dust and the discharge part 40 from the outer surface of the dust collecting body 10 and the dust collecting housing 30. Electric force is pushed out in the inner direction.
따라서, 대전된 분진이 원심력 및 관성력과 전기력에 의해 집진체(10)의 내벽으로 이동하여 포집되어 제거되거나 슬릿(13)을 통과하여 집진체(10)와 집진 하우징(30)의 사이공간으로 이동한 후 제거된다. 따라서 전기력이 작용하지 않는 경우에 비해 본 발명의 싸이클론에서는 전기력에 의한 집진이 추가로 이루어지기 때문에 집진효율이 증가하게 된다. 특히 전기력이 작용되는 경우 입경이 작은 분진의 경우에 전기이동도 상승효과가 크기 때문에 미세한 분진에 대한 집진효율이 보다 큰 폭으로 개선될 수 있다. 도 6에는 분진 입경크기에 따른 분진 입자(2)의 거동 특성이 나타나 있다. 즉, 입경이 큰 분진 입자는 원심력과 관성력만으로도 슬릿(13)으로 유인되어 제거되지만, 입경이 작은 분진 입자의 경우에는 전기력이 적용되었을 때 보다 효과적으로 슬릿(13) 내부로 유인되어 제거될 수 있다. 싸이클론 자체의 선회유동에 의한 원심력 효과도 전기력이 작용할 때 당연히 증가되기 때문에 슬릿(13)으로 유인되지 않더라도 집진체(10) 내부의 선회유동에 의한 분진 제거 효율도 전기력이 작용하였을 때 더 증가하게 된다. Therefore, the charged dust is moved to the inner wall of the dust collecting body 10 by centrifugal force, inertial force, and electric force, and is collected and removed or passed through the slit 13 to move between the dust collecting body 10 and the dust collecting housing 30. And then removed. Therefore, in the cyclone of the present invention, the dust collection efficiency is increased because the dust collection by the electric force is additionally performed compared to the case where the electric force does not work. In particular, when the electric force is applied, since the electric mobility has a large synergistic effect in the case of dust having a small particle size, the dust collection efficiency for fine dust can be significantly improved. 6 shows the behavior characteristics of the dust particles 2 according to the particle size. That is, dust particles having a large particle diameter are attracted and removed by the slit 13 only by centrifugal force and inertia force, but in the case of dust particles having a small particle diameter, they can be more effectively attracted and removed into the slit 13 when electric force is applied. Since the effect of centrifugal force due to the rotational flow of the cyclone itself increases naturally when the electric force is applied, even if it is not attracted to the slit 13, the efficiency of removing dust due to the rotational flow inside the dust collector 10 also increases when the electric force is applied. do.
즉, 본 발명의 제1실시예에 따른 싸이클론 집진장치(1)는 압력손실을 극복하기 위해 이중 외벽 구조를 갖고 슬릿(13)이 형성된 집진체(10)를 채용하면서, 동시에 분진 입자를 전기적으로 대전하고 배출부(40)와 집진 하우징(30) 사이에 전기장을 형성하여 전기 집진원리를 적용함으로써 집진체(10) 내벽으로 이동되어 싸이클론 작용에 의해 제거되거나, 슬릿(13)으로 빠져나가 제거되는 분진의 양을 현저히 증가시켜 집진효율을 상승시키게 된다. That is, the cyclone dust collecting device 1 according to the first embodiment of the present invention adopts a dust collecting body 10 having a double outer wall structure and a slit 13 to overcome pressure loss, while simultaneously discharging dust particles. By charging and forming an electric field between the discharge part 40 and the dust collecting housing 30, it is moved to the inner wall of the dust collecting body 10 by applying an electric dust collecting principle, or is removed by a cyclone action, or exited into the slit 13 The amount of dust to be removed is significantly increased to increase dust collection efficiency.
한편, 전압인가부(70)가 배출부(40)에 제1전압을 인가시키고, 집진체(10)에 제1전압보다 낮은 제2전압을 인가시키고, 집진 하우징(30)은 접지시킬 수도 있다.Meanwhile, the voltage applying unit 70 may apply the first voltage to the discharge unit 40, apply the second voltage lower than the first voltage to the dust collector 10, and the dust collecting housing 30 may be grounded. .
예를 들어, 전압인가부(70)가 배출부(40)에 10kV의 전압을 인가하고, 집진체(10)에 2kV의 전압을 인가하게 되면, 배출부(40)와 집진체(10) 사이에 8kV의 전위차가 발생되고, 또한 집진체(10)와 집진 하우징(30) 사이에 2kV의 전위차가 발생되게 된다. For example, when the voltage applying unit 70 applies a voltage of 10 kV to the discharge unit 40 and applies a voltage of 2 kV to the dust collector 10, between the discharge unit 40 and the dust collector 10 A potential difference of 8 kV is generated, and a potential difference of 2 kV is generated between the dust collecting body 10 and the dust collecting housing 30.
따라서 집진체(10) 내로 유입된 함진 가스 내의 분진이 (+)로 대전되어 있다면, 배출부(40) 외면에서 집진체(10) 내면 방향으로의 전기력과, 집진체(10) 외면에서 집진 하우징(30) 내면 방향으로의 전기력에 의해 대전된 분진이 보다 높은 효율로 집진체(10) 내벽으로 이동하여 제거되거나, 슬릿(13)을 통과하여 집진체(10)와 상기 집진 하우징(30)의 사이공간으로 이동되어 제거된다. Therefore, if the dust in the impregnated gas introduced into the dust collecting body 10 is charged to (+), the electric force from the outer surface of the discharge part 40 toward the inner surface of the dust collecting body 10 and the dust collecting housing from the outer surface of the dust collecting body 10 (30) The dust charged by the electric force in the inner surface direction moves to the inner wall of the dust collecting body 10 with higher efficiency, or is removed or passes through the slits 13 of the dust collecting body 10 and the dust collecting housing 30 It is moved to the interspace and removed.
또한, 도 6에 도시되지는 않았지만 별도의 제어부(80)를 통해 전압인가부(70)를 제어하여 배출부(40)와 집진 하우징(30) 사이의 전위차를 조절할 수 있다. In addition, although not illustrated in FIG. 6, the voltage difference between the discharge unit 40 and the dust collecting housing 30 may be controlled by controlling the voltage application unit 70 through a separate control unit 80.
이와 같이, 전압인가부(70)는 집진체(10) 및 배출부(40) 중 어느 하나 이상에 전압을 인가하여 전위차를 발생시켜 대전된 분진이 집진체(10) 내벽으로 이동하여 제거되거나 슬릿(13)을 통과하여 제거되도록 마련될 수 있다.As described above, the voltage applying unit 70 applies a voltage to any one or more of the dust collecting body 10 and the discharge part 40 to generate a potential difference so that the charged dust moves to the inner wall of the dust collecting body 10 and is removed or slits. It may be provided to be removed through (13).
도 7은 본 발명의 제2실시예에 따른 집진원리를 나타내기 위한 싸이클론 집진장치(1)의 평단면도를 도시한 것이다. 7 is a cross-sectional view of a cyclone dust collecting device 1 for showing a dust collecting principle according to a second embodiment of the present invention.
도 7에 도시된 것처럼, 제2 실시예에 따른 싸이클론 집진장치(1)는 제1 실시예에 따른 싸이클론 집진장치(1)와 실질적으로 동일한 구성으로 마련되고, 집진 하우징(30)은 단면이 원형인 형태를 갖는다. 도 7과 같이 집진하우징(30)의 단면이 원형인 경우, 집진하우징(30) 단면이 사각형인 경우에 비해 배출부(40) 및 집진체(10)와 집진하우징(30) 사이의 간격을 일정하게 할 수 있기 때문에 전압 인가시 싸이클론 집진장치(1) 내부에 보다 균일한 전기장이 형성됨으로써 안정적인 운전과 높은 집진효율을 달성할 수 있게 된다.As shown in FIG. 7, the cyclone dust collecting device 1 according to the second embodiment is provided in substantially the same configuration as the cyclone dust collecting device 1 according to the first embodiment, and the dust collecting housing 30 is cross-sectioned. It has a circular shape. When the cross section of the dust collecting housing 30 is circular as shown in FIG. 7, the distance between the discharge part 40 and the dust collecting body 10 and the dust collecting housing 30 is constant compared to the case where the dust collecting housing 30 has a rectangular cross section. Since a more uniform electric field is formed inside the cyclone dust collector 1 when voltage is applied, stable operation and high dust collection efficiency can be achieved.
도 8은 본 발명의 제3실시예에 따른 집진장치 구성과 집진원리를 나타내기 위한 싸이클론 집진장치(1)의 평단면도이다.8 is a cross-sectional plan view of a cyclone dust collector 1 for showing the dust collecting device configuration and dust collecting principle according to the third embodiment of the present invention.
도 8에 도시된 바와 같이, 본 발명의 제3실시예에 따른 싸이클론 집진장치(1)는 앞서 언급한 제1실시예와 유사하나 전압인가부(70)가 제1전압인가부(71)와 제2전압인가부(72)를 포함하여 구성될 수 있음을 알 수 있다. 즉, 제1전압인가부(71)는 배출부(40) 및 집진 하우징(30) 사이에 전압을 인가하고, 제2전압인가부(72)는 집진체(10) 및 집진 하우징(30) 사이에 전압을 인가할 수 있다. 이때, 집진 하우징(30)은 접지된 상태일 수 있다. 또한 제1 전압인가부(71)에 의해 배출부(40)와 집진 하우징(30) 사이에 인가된 전위는 제2전압인가부(72)에 의해 집진체(10) 및 집진 하우징(30) 사이에 인가된 전위에 비해 낮은 값을 갖도록 제어하는 것이 바람직하다. 여기서 전위는 두 지점 사이의 절대적인 전압차이를 의미한다. 8, the cyclone dust collecting device 1 according to the third embodiment of the present invention is similar to the first embodiment mentioned above, but the voltage applying unit 70 has a first voltage applying unit 71. And a second voltage applying unit 72. That is, the first voltage applying unit 71 applies a voltage between the discharge unit 40 and the dust collecting housing 30, and the second voltage applying unit 72 is between the dust collecting body 10 and the dust collecting housing 30. Voltage can be applied. At this time, the dust collecting housing 30 may be grounded. In addition, the potential applied between the discharge part 40 and the dust collecting housing 30 by the first voltage applying part 71 is between the dust collecting body 10 and the dust collecting housing 30 by the second voltage applying part 72. It is preferable to control to have a lower value than the potential applied to. The potential here means the absolute voltage difference between the two points.
그리고, 도 8에 도시되지는 않았지만 별도의 제어부(80)를 통해 제1 실시예와 유사한 방식으로 제1전압인가부(71)와 제2전압인가부(72)를 제어하여, 집진체(10), 배출부(40) 및 집진 하우징(30) 사이의 전위차를 조절함으로써 대전된 분진이 집진체(10) 내벽으로 이동하여 제거되거나 슬릿(13)을 통과하여 집진체(10)와 집진 하우징(30) 사이 공간으로 이동하여 제거될 수 있다. In addition, although not illustrated in FIG. 8, the first voltage applying unit 71 and the second voltage applying unit 72 are controlled in a similar manner to the first embodiment through a separate control unit 80 to collect the dust collecting body 10. ), by controlling the potential difference between the discharge portion 40 and the dust collecting housing 30, charged dust is removed by moving to the inner wall of the dust collecting body 10 or passing through the slit 13, thereby collecting the dust collecting body 10 and the dust collecting housing ( 30) can be removed by moving to the interspace.
도 9는 본 발명의 제4실시예에 따른 집진장치 구성과 집진원리를 나타내기 위한 싸이클론 집진장치(1)의 평단면도이다.9 is a cross-sectional plan view of a cyclone dust collector 1 for showing a dust collecting device configuration and a dust collecting principle according to a fourth embodiment of the present invention.
도 9에 도시된 것처럼, 제4 실시예에 따른 싸이클론 집진장치는 제3 실시예에 따른 싸이클론 집진장치와 실질적으로 동일한 구성으로 마련되나, 집진 하우징(30)만 원형 형태임을 보여준다.As illustrated in FIG. 9, the cyclone dust collecting device according to the fourth embodiment is provided in substantially the same configuration as the cyclone dust collecting device according to the third embodiment, but shows that only the dust collecting housing 30 is circular.

도 11에 도시된 바와 같이, 본 발명의 제5실시예에 따른 싸이클론 집진장치(1)는 앞서 언급한 제2실시예와 유사한 구성을 가지고 있으나, 배출부(40) 외면에 다수개의 방전침(41)이 구비되는 차이점이 있다. 11, the cyclone dust collector 1 according to the fifth embodiment of the present invention has a configuration similar to the second embodiment mentioned above, but a plurality of discharge needles on the outer surface of the discharge unit 40 There is a difference that 41 is provided.

In the fifth embodiment, as in the above-described second embodiment, the voltage applying unit 70 applies a voltage to form a potential difference between the discharge unit 40 and the dust collecting body 10, and the dust collecting housing 30 Can be grounded. 11, if the dust collecting body 10 and the dust collecting housing 30 are not electrically insulated, the dust collecting body 10 is also grounded together with the dust collecting housing 30.
그리고, 본 발명의 제5실시예에서는 배출부(40) 외면에, 집진체(10)의 내면 방향으로 돌출되는, 다수개의 방전침(41)을 형성하고 배출부(40)에 고전압을 인가하여 방전침(41)에서 코로나(coroana) 방전현상이 발생되도록 함으로써 유입부(20)를 통해 집진체(10) 내로 유입된 함진가스 내의 분진을 대전시킬 수 있게 된다. 즉, 제5실시예에서는 별도의 방전수단(21)을 유입부(20)에 설치하지 않고도, 배출부(40) 외면에 방전침(41)을 구비함으로써, 집진체(10) 내로 유입된 함진 가스 내의 분진을 대전시킬 수 있게 되고, 대전된 분진은 전기력이 추가로 작용함으로써 집진체(10) 내벽에 포집되거나 슬릿(13)을 통과하여 집진 하우징(30)과 집진체(10) 사이 공간으로 이동되어 포집 제거된다. 여기서 방전침(41)은 집진체(10) 내벽과의 사이에 코로나(corona)를 발생시킬 수 있는 다양한 형상으로 구성될 수 있다.In addition, in the fifth embodiment of the present invention, a plurality of discharge needles 41 protruding in the direction of the inner surface of the dust collecting body 10 are formed on the outer surface of the discharge unit 40 and high voltage is applied to the discharge unit 40.

도 12는 본 발명의 제6실시예에 따른 집진장치 구성과 집진원리를 나타내기 위한 싸이클론 집진장치(1)의 평단면도를 도시한 것이다.12 is a cross-sectional view of a cyclone dust collector 1 for showing a dust collecting device configuration and dust collecting principle according to a sixth embodiment of the present invention.
도 12에 도시된 바와 같이, 본 발명의 제6실시예에 따른 싸이클론 집진장치(1)는 앞서 언급한 제5실시예와 유사한 구성을 가지고 있으나, 배출부(40) 외면과 집진체(10) 내면에 다수 개의 돌출부(31)가 형성되어 있으며, 집진 하우징(30) 내면에도 집진체(10)에 형성된 슬릿(13)에 대응되는 위치에 다수 개의 돌출부(31)가 구비되어 있는 차이점이 있다. 12, the cyclone dust collecting device 1 according to the sixth embodiment of the present invention has a configuration similar to that of the fifth embodiment mentioned above, but the outer surface of the discharge part 40 and the dust collecting body 10 ) There is a difference in that a plurality of protrusions 31 are formed on the inner surface, and a plurality of protrusions 31 are provided at positions corresponding to the slits 13 formed in the dust collecting body 10 on the inner surface of the dust collecting housing 30. .
도 12에 나타낸 돌출부(31)는 도 11의 방전침(41)과는 다르게 코로나(corona) 발생을 주목적으로 하지는 않지만 돌출부(31)의 형상과 배치에 따라 코로나가 발생할 수도 있다. 돌출부(31)의 도입 목적은 배출부(40)와 집진체(10), 그리고 집진 하우징(30) 사이에 돌출부(31)에 의한 전기장 집중현상이 발생하도록 함으로써 분진입자에 작용하는 전기력의 세기를 증가시켜 궁극적으로 싸이클론 집진장치(1)의 집진효율을 향상시키는데 있다. 일반적으로 분진입자에 작용하는 전기력의 세기는 전기장의 크기와 분진입자 대전량의 곱에 비례한다. 전기장은 동일한 전압이 인가되었을 때 전극의 형상에 따라 공간 분포가 달라지게 되는데 평평한 전극판보다는 돌출부가 형성된 전극판을 적용하는 경우 돌출부를 중심으로 전기장이 집중되고 높은 세기의 전기장이 돌출부 주변에 형성된다. 따라서 분진 입자가 돌출부(31) 근방을 지나갈 때 분진입자에 작용하는 전기력은 돌출부가 형성되지 않은 경우에 비해 보다 높은 값을 갖게 되고 이로 인해 분진입자가 돌출부(31) 방향으로 유인되고 결과적으로 집진체 또는 집진 하우징에 포집되어 제거된다. 본 발명의 제6실시예에서는 이러한 전기장 집중현상을 이용하여 싸이클론 집진장치(1)의 집진효율을 높일 수 있는 구성을 제시하고 있다.Unlike the discharge needle 41 of FIG. 11, the protrusion 31 shown in FIG. 12 does not primarily generate corona, but corona may occur depending on the shape and arrangement of the protrusion 31. The purpose of introducing the protrusion 31 is to increase the intensity of the electric force acting on the dust particles by causing the electric field to be concentrated by the protrusion 31 between the discharge part 40, the dust collecting body 10, and the dust collecting housing 30. It is to increase the dust collection efficiency of the cyclone dust collector 1 ultimately. In general, the strength of the electric force acting on the dust particles is proportional to the product of the size of the electric field and the charge amount of the dust particles. When the same voltage is applied, the spatial distribution varies depending on the shape of the electrode. When applying an electrode plate with a protrusion rather than a flat electrode plate, the electric field is concentrated around the protrusion and a high-intensity electric field is formed around the protrusion. . Therefore, when the dust particles pass near the protrusion 31, the electric force acting on the dust particles has a higher value than when the protrusion is not formed, whereby the dust particles are attracted in the direction of the protrusion 31 and consequently a dust collector. Or it is collected and removed in the dust collecting housing. In the sixth embodiment of the present invention, a configuration capable of increasing the dust collection efficiency of the cyclone dust collecting device 1 is proposed by using such an electric field concentration phenomenon.

또한, 상기 커버부재(94)의 내부에는 유입관(91)측에서부터 배출관(92)측을 향해 일정각도 경사지는 분배판(95)을 구비하여, 상기 커버부재(94) 내부가 분배판(95)을 기준으로 상단부와 하단부로 분할되도록 하되, 상기 분배판(95)의 저면에는 다수개의 집진체(10)에 결합되어 있는 다수개의 배출부(40)가 연통결합되도록 한다. 물론, 이를 위해 상기 분배판(95)에는 등간격으로 이격천공된 결합공이 형성되어 있어야 할 것이다. 즉, 도 18에서 보는 바와 같이, 분배판(95)이 기울어져 있는 형태이기에, 상기 다수개의 배출부(40)들 또한, 배출관(92)측에 가까워지는 질수록 배출부(40)의 전장이 짧아져 상호간 상이한 길이를 가져야 함은 당연하다. 또한, 다수의 집진체(10)에 함진 가스를 유입하기 위해선 상기 배출관(92)의 결합위치는 유입관(91)의 결합위치 보다 상대적으로 더 높아야 한다.In addition, the inside of the cover member 94 is provided with a distribution plate 95 that is inclined at a constant angle from the inlet pipe 91 side to the discharge pipe 92 side, so that the inside of the cover member 94 is distribution plate 95 ) To be divided into an upper portion and a lower portion, but a plurality of discharge portions 40 coupled to a plurality of dust collecting bodies 10 are communicated with each other on the bottom surface of the distribution plate 95. Of course, for this purpose, the distribution plate 95 should have a coupling hole spaced apart at equal intervals. That is, as shown in FIG. 18, since the distribution plate 95 is inclined, the length of the discharge part 40 increases as the plurality of discharge parts 40 are closer to the discharge pipe 92 side. It is natural that they should be shortened to have different lengths. In addition, in order to introduce the impregnated gas into the plurality of dust collecting bodies 10, the coupling position of the discharge pipe 92 should be relatively higher than that of the inlet pipe 91.
이로써, 상기 유입관(91)으로 유입되는 함진 가스는 분배판(95)의 하단부로 유입되어 다수개의 집진체(10) 유입부(20)로 내입되고, 분진이 처리된 처리 가스는 분배판(95)의 상단부로 유동되어, 상기 분배판(95)의 타단에 결합되어 있는 배출관(92)을 통해 외부로 배출되게 된다.Thus, the impregnated gas flowing into the inlet pipe 91 flows into the lower end of the distribution plate 95 and is introduced into the plurality of dust collecting bodies 10 and the inlet 20, and the processed gas treated with dust is distributed through the distribution plate ( 95), it is discharged to the outside through the discharge pipe 92 coupled to the other end of the distribution plate (95).
