Description

本発明は、空気中で帯電させた塵埃を捕集する集塵装置に関するものである。   The present invention relates to a dust collector that collects dust charged in the air.

従来より、空気通路と、該空気通路内に設置された荷電部と、上記荷電部の下流側に設置された集塵部とを備えた静電式の電気集塵装置が知られている(特許文献1参照)。上記電気集塵装置は、空気流路内に導入された空気中の塵埃を吸着捕集して、塵埃を含む空気を浄化させるためのものである。具体的には、まず、上記電気集塵装置の荷電部が上記空気通路内に流入した塵埃を正帯電させる。次に、上記集塵部が荷電部により正帯電した塵埃を吸着捕集する。これにより、塵埃を含む空気から塵埃を分離して、空気を浄化することができる。   Conventionally, an electrostatic electrostatic precipitator including an air passage, a charging unit installed in the air passage, and a dust collecting unit installed on the downstream side of the charging unit is known ( Patent Document 1). The electric dust collector is for adsorbing and collecting dust in the air introduced into the air flow path and purifying the air containing the dust. Specifically, first, the charging unit of the electrostatic precipitator positively charges the dust flowing into the air passage. Next, the dust collection unit sucks and collects dust positively charged by the charging unit. Thereby, dust can be separated from air containing dust and air can be purified.

ここで、特許文献1の集塵部は、平板状に形成された集塵電極及び同形状の高圧電極を有しており、上記集塵電極と上記高圧電極とが交互に平行配列されている。上記集塵電極が接地されると共に、上記高圧電極が上記電気集塵装置に設けられた電源部の正極側に接続されている。そして、上記電源部により電圧が印加されて、上記高圧電極と上記集塵電極との間に所定の電位差が生じる。この所定の電位差が生じた空間内に正帯電した塵埃が流入して、該塵埃が接地された集塵電極に吸着捕集される構成となっている。

The dust collection electrode is grounded, and the high-voltage electrode is connected to the positive electrode side of the power supply unit provided in the electric dust collector. A voltage is applied by the power supply unit, and a predetermined potential difference is generated between the high-voltage electrode and the dust collection electrode.

Japanese Patent Laid-Open No. 1-310753

ところで、このように上記電気集塵装置の運転中に、集塵部の集塵電極の表面に塵埃が付着して堆積していくと、上記集塵電極及び上記高圧電極の電極間の抵抗が下がり、該電極間に過剰な電流が流れてスパーク(火花放電)が生じることがある。また、上記集塵部に流入する正帯電した塵埃中に導電性粉塵が混在することによっても、該電極間に過剰な電流が流れてスパークが生じることがある。つまり、通常の運転状態において、何らかの影響で上記電極間の抵抗が下がることにより、該電極間にスパークが生じてしまう。このスパークを抑制するために、上記電源部の印加電圧を所定値より下げたり、上記電極間の距離を所定値より長くすれば、スパークは抑えることができるものの、上記集塵部の集塵能力は所期の能力に対して大きく低下してしまう。   By the way, when the dust is deposited and deposited on the surface of the dust collecting electrode of the dust collecting unit during the operation of the electric dust collector, the resistance between the dust collecting electrode and the electrode of the high voltage electrode is reduced. In some cases, an excessive current flows between the electrodes and a spark (spark discharge) may occur. Further, even when conductive dust is mixed in the positively charged dust flowing into the dust collecting portion, an excessive current may flow between the electrodes to cause sparks. That is, in a normal operation state, a spark is generated between the electrodes due to a decrease in resistance between the electrodes due to some influence. In order to suppress this spark, if the applied voltage of the power supply unit is lowered from a predetermined value or the distance between the electrodes is made longer than a predetermined value, the spark can be suppressed, but the dust collecting ability of the dust collecting unit Is greatly reduced with respect to the intended ability.

本発明は、かかる点に鑑みてなされたものであり、その目的は、上記集塵部での集塵能力の低下を抑えつつ、上記集塵部における電極間のスパークの発生を抑制することである。   This invention is made | formed in view of this point, The objective is suppressing generation | occurrence | production of the spark between the electrodes in the said dust collection part, suppressing the fall of the dust collection capability in the said dust collection part. is there.

第1の発明は、空気中の塵埃を帯電させる荷電部(12)と、第1電極(40)と該第1電極(40)の近傍に設置された第2電極(50)とを有する集塵部(30)と、上記集塵部(30)に電圧を印加する電源部とを備えた集塵装置を前提としている。   The first aspect of the present invention is a collector having a charging unit (12) for charging dust in the air, a first electrode (40), and a second electrode (50) installed in the vicinity of the first electrode (40). A dust collector including a dust part (30) and a power supply part that applies a voltage to the dust collection part (30) is assumed.

そして、上記集塵装置の荷電部(12)が、上記塵埃を正に帯電する帯電手段(12a)を備える一方、第1電極(40)或いは第2電極(50)のどちらか一方の電極(50)が上記電源部の正極側に接続され、他方の電極(40)が接地され、上記接地された電極(40)が導電性樹脂材で形成されていることを特徴としている。ここで、上記接地された電極(40)は、上記集塵装置において、帯電した塵埃を吸着捕集する集塵電極(40)として構成されている。   The charging unit (12) of the dust collector includes a charging means (12a) for positively charging the dust, while either the first electrode (40) or the second electrode (50) ( 50) is connected to the positive electrode side of the power supply section, the other electrode (40) is grounded, and the grounded electrode (40) is formed of a conductive resin material. Here, the grounded electrode (40) is configured as a dust collection electrode (40) for adsorbing and collecting charged dust in the dust collector.

第1の発明では、接地された電極(集塵電極)(40)を導電性樹脂で形成することにより、例えば金属で形成された電極と比べて、該集塵電極(40)の体積抵抗率を上げることが可能となる。   In the first invention, by forming the grounded electrode (dust collecting electrode) (40) from a conductive resin, the volume resistivity of the dust collecting electrode (40) compared to, for example, a metal-made electrode. Can be raised.

第2の発明は、第1の発明において、上記導電性樹脂材の体積抵抗率が、10Ωcm以上1012Ωcm以下であることを特徴としている。 According to a second invention, in the first invention, the conductive resin material has a volume resistivity of 10 8 Ωcm or more and 10 12 Ωcm or less.

第2の発明では、上記導電性樹脂材の体積抵抗率を規定することにより、集塵電極(40)に所定の体積抵抗率を付与することができる。ここで、上記導電性樹脂材の体積抵抗率が低すぎれば樹脂としての特性が失われスパークしやすくなり、逆に上記導電性樹脂材の体積抵抗率が高すぎれば、塵埃が接近してきた時の集塵電極(40)内の電荷の移動が遅くなるので、集塵電極(40)の表面への電荷の移動も遅くなり、結果として集塵部(30)の集塵能力が大きく低下してしまう。第2の発明のように上記導電性樹脂材の体積抵抗率を規定することにより、上記集塵電極(40)を、樹脂としての特性を維持しつつ集塵部(30)の集塵能力の低下を抑えた電極を構成することができる。   In 2nd invention, a predetermined | prescribed volume resistivity can be provided to a dust collection electrode (40) by prescribing | regulating the volume resistivity of the said conductive resin material. Here, if the volume resistivity of the conductive resin material is too low, the characteristic as a resin is lost and sparking easily occurs. Conversely, if the volume resistivity of the conductive resin material is too high, dust approaches. Since the movement of charge in the dust collection electrode (40) is slow, the movement of charge to the surface of the dust collection electrode (40) is also slowed. As a result, the dust collection capacity of the dust collection section (30) is greatly reduced. End up. By defining the volume resistivity of the conductive resin material as in the second aspect of the invention, the dust collection electrode (40) can maintain the characteristics as a resin while maintaining the dust collection capacity of the dust collection portion (30). An electrode that suppresses the decrease can be configured.

Thus, when the volume resistivity is applied to the electrodes (40, 50) of the dust collection part (30), the volume resistivity of the conductive resin of the dust collection electrode (40) and the high voltage electrode (50) Within the range, a volume resistivity suitable for both electrodes (40, 50) can be set.

第4の発明は、空気中の塵埃を帯電させる荷電部(12)と、第1電極(40)と該第1電極(40)の近傍に設置された第2電極(50)とを有する集塵部(30)と、上記集塵部(30)に電圧を印加する電源部とを備えた集塵装置を前提としている。   According to a fourth aspect of the present invention, there is provided a collector having a charging unit (12) for charging dust in the air, a first electrode (40), and a second electrode (50) installed in the vicinity of the first electrode (40). A dust collector including a dust part (30) and a power supply part that applies a voltage to the dust collection part (30) is assumed.

そして、上記集塵装置の荷電部(12)が、上記塵埃を負に帯電する帯電手段(12a)を備える一方、第1電極(40)或いは第2電極(50)のどちらか一方の電極(50)が上記電源部の負極側に接続され、他方の電極(40)が接地され、上記接地された電極(40)が導電性樹脂材で形成されていることを特徴としている。   The charging unit (12) of the dust collector includes a charging unit (12a) for negatively charging the dust, while either the first electrode (40) or the second electrode (50) ( 50) is connected to the negative electrode side of the power supply section, the other electrode (40) is grounded, and the grounded electrode (40) is formed of a conductive resin material.

第4の発明では、第1の発明と同様に、接地された電極(集塵電極)(40)を導電性樹脂で形成することにより、例えば金属で形成された電極と比べて、該集塵電極(40)の体積抵抗率を上げることが可能となる。   In the fourth invention, as in the first invention, the grounded electrode (dust collection electrode) (40) is formed of a conductive resin, so that the dust collection is compared with, for example, an electrode formed of metal.

上記送風機(14)は、ケーシング(20)内の空気通路(23)において最下流側に配置され、室内空気をケーシング(20)内に吸い込み、清浄空気を室内に吹き出すためのものである。   The blower (14) is disposed on the most downstream side in the air passage (23) in the casing (20), and sucks room air into the casing (20) and blows clean air into the room.

−運転動作−
次に、上記空気清浄機(10)の空気清浄動作について説明する。
-Driving action-
Next, the air cleaning operation of the air cleaner (10) will be described.

図1及び図2に示すように、上記空気清浄機(10)は、送風機(14)を駆動すると、室内空気がケーシング(20)の空気通路(23)に吸引され、該空気通路(23)を流れることになる。   As shown in FIGS. 1 and 2, when the air cleaner (10) drives the blower (14), indoor air is sucked into the air passage (23) of the casing (20), and the air passage (23) Will flow.

一方、荷電部(12)のイオン化線(12a)と対向電極(12b)と間には直流電圧が印加される一方、集塵部(30)の集塵電極(40)と高圧電極(50)との間にも直流電圧が印加されている。   On the other hand, a DC voltage is applied between the ionization line (12a) of the charging part (12) and the counter electrode (12b), while the dust collection electrode (40) and the high voltage electrode (50) of the dust collection part (30). A DC voltage is also applied between the two.

そして、室内空気がケーシング(20)の空気通路(23)に吸引されると、先ず、上記プレフィルタ(11)は、室内空気に含まれる比較的大きな塵埃を捕集する。   When indoor air is sucked into the air passage (23) of the casing (20), the prefilter (11) first collects relatively large dust contained in the indoor air.

上記プレフィルタ(11)を通過した室内空気は荷電部(12)に流れる。この荷電部(12)において、上記プレフィルタ(11)を通過した比較的小さな塵埃が帯電し、例えば、塵埃が正極に帯電し、この帯電した塵埃が下流側に流れることになる。   The room air that has passed through the prefilter (11) flows to the charging section (12). In the charging unit (12), relatively small dust that has passed through the prefilter (11) is charged. For example, the dust is charged to the positive electrode, and the charged dust flows downstream.

続いて、帯電した塵埃は集塵部(30)に流れ、集塵電極(40)と高圧電極(50)における基台部材(41,51)の通風孔(46,56)を流れることになる。つまり、集塵電極(40)と高圧電極(50)の基台部材(41,51)における枠体(43,53)と縦仕切部材(44,54)と横仕切部材(45,55)とで形成される通風孔(46,56)を室内空気が流れ、集塵電極(40)と高圧電極(50)の突起部材(42,52)の周囲を室内空気が流れる。   Subsequently, the charged dust flows into the dust collecting portion (30) and flows through the ventilation holes (46, 56) of the base member (41, 51) in the dust collecting electrode (40) and the high voltage electrode (50). . That is, the frame body (43, 53), the vertical partition member (44, 54) and the horizontal partition member (45, 55) in the base member (41, 51) of the dust collection electrode (40) and the high voltage electrode (50) The room air flows through the ventilation holes (46, 56) formed in the above, and the room air flows around the protrusions (42, 52) of the dust collection electrode (40) and the high voltage electrode (50).

その際、集塵電極(40)は、例えば、アース電極になっているので、正極に帯電した塵埃が電気影像力により集塵電極(40)に吸着することになる。つまり、上記塵埃は、集塵電極(40)における枠体(43)の内表面、縦仕切部材(44)の表面、横仕切部材(45)の表面及び突起部材(42)の表面に吸着することになる。   At this time, since the dust collection electrode (40) is, for example, a ground electrode, dust charged to the positive electrode is adsorbed to the dust collection electrode (40) by the electric image force. That is, the dust is adsorbed on the inner surface of the frame (43), the surface of the vertical partition member (44), the surface of the horizontal partition member (45), and the surface of the protruding member (42) in the dust collection electrode (40). It will be.

その後、上記塵埃が除去された室内空気は、触媒フィルタ(13)を流れ、空気中の有害物質や臭気物質が分解除去され、清浄空気となる。この清浄空気は、送風機(14)を通り、空気通路(23)から室内に吹き出されることになる。この動作を繰り返し、室内を清浄化する。   Thereafter, the room air from which the dust has been removed flows through the catalyst filter (13), and harmful substances and odorous substances in the air are decomposed and removed to become clean air. This clean air passes through the blower (14) and is blown out into the room from the air passage (23). This operation is repeated to clean the room.

−実施形態の効果−
上記実施形態によれば、上記集塵電極(40)を導電性樹脂で形成することにより該集塵電極(40)の体積抵抗率を上げることができるので、何らかの影響で上記集塵電極(40)及び上記高圧電極(50)の電極間で抵抗が下がったとしても、電極間に過剰な電流が流れてしまうのを防止することができる。つまり、上記集塵部(30)の集塵電極(40)の表面に塵埃が付着し堆積した場合や、上記集塵部(30)に流入する正帯電した塵埃中に導電性粉塵が混在した場合であっても、電極間に過剰な電流が流れてしまうのを防止することができるので、結果としてスパークの発生を抑制することが可能である。
-Effect of the embodiment-
According to the embodiment, since the volume resistivity of the dust collecting electrode (40) can be increased by forming the dust collecting electrode (40) with a conductive resin, the dust collecting electrode (40 ) And the high-voltage electrode (50), even if the resistance decreases, it is possible to prevent an excessive current from flowing between the electrodes.

Even in this case, it is possible to prevent an excessive current from flowing between the electrodes, and as a result, the occurrence of sparks can be suppressed.

又、上記集塵電極(40)の体積抵抗率を10Ωcm以上1012Ωcm以下とし、上記高圧電極(50)の体積抵抗率を10Ωcm以上10Ωcm以下とすることにより、集塵部(30)の集塵能力の低下を抑えつつ、スパークの発生を抑制することができる。 Further, the volume resistivity of the dust collection electrode (40) is set to 10 8 Ωcm or more and 10 12 Ωcm or less, and the volume resistivity of the high voltage electrode (50) is set to 10 3 Ωcm or more and 10 8 Ωcm or less.
