It is arranged concentrically and shields portions other than the exhaust flow path member so that the exhaust flow passes only through the exhaust flow path member.

本第２発明は、本第１発明の液体スプレイ噴霧装置を備えた除塵排気塔において、前記排気流路部材の前後面の少なくとも液体スプレイ噴霧装置の液体噴霧方向側に水膜生成用網を１枚以上配置することを特徴とする。   According to the second aspect of the present invention, in the dust removal exhaust tower provided with the liquid spray spraying device of the first invention, a water film generating net is provided at least on the liquid spraying direction side of the liquid spray spraying device on the front and rear surfaces of the exhaust passage member. It is characterized by arranging at least one sheet.

本発明の液体スプレイ噴霧装置を備えた除塵排気塔では、発塵源が存在する建物、構造物及びその他の建造物に形成される自然換気の排気口に設置される排気塔に、液体スプレイ噴霧装置を設置する構成により、上昇気流に乗って建物、構造物及びその他の建造物から外部に排出される手前で液体スプレイ噴霧装置から噴霧される液体により粉塵が液体と結びつき質量が増加することで排気流中の粉塵が分離回収でき、従来の湿式機械集塵方法より設備費が安価でメンテナンスフリーであるため、極めて安い費用により大きな除塵効果を得ることが可能となる。   In the dust removal exhaust tower provided with the liquid spray spray device of the present invention, the liquid spray spray is applied to the exhaust tower installed at the natural ventilation exhaust port formed in the building, structure and other structures where the dust generation source exists. By installing the device, the dust is combined with the liquid by the liquid sprayed from the liquid spray spray device before it is discharged from the building, structure and other structures on the rising airflow, and the mass increases. Dust in the exhaust stream can be separated and recovered, and the equipment cost is lower and maintenance-free than the conventional wet mechanical dust collection method. Therefore, a large dust removal effect can be obtained at an extremely low cost.

自然換気の排気口に、断面円形の排気流路部材を所定の間隔で複数設置し、その排気流路部材内に、その排気流路部材の軸方向から見て円形の液体スプレイ噴霧装置を同心状に配置し、前記排気流路部材内のみに排気流が通過するように前記排気流路部材以外の部分を遮蔽する構成により、液体スプレイ噴霧装置から狭隘な排気流路部材内に噴出された直後の液体中を排気流が通過し、排気流中の粉塵と液体の付着効果を向上することができる。 A plurality of exhaust passage members having a circular cross section are installed at a predetermined interval at the exhaust port for natural ventilation, and a circular liquid spray spray device is concentric in the exhaust passage member when viewed from the axial direction of the exhaust passage member. The liquid spray spray device sprayed into the narrow exhaust passage member by arranging the portion other than the exhaust passage member so that the exhaust flow passes only in the exhaust passage member. The exhaust stream passes through the liquid immediately after it, and the adhesion effect of the dust and the liquid in the exhaust stream can be improved.

排気流路部材の前後面の少なくとも液体スプレイ噴霧装置の液体噴霧方向側に水膜生成用網を１枚以上配置する構成により、排気流路部材内を通過する排気流が確実に水膜を通過するので排気流中の粉塵と液体の付着効果をより一層向上することができる。   The structure in which one or more water film generating nets are arranged at least on the liquid spraying direction side of the liquid spray spray device on the front and rear surfaces of the exhaust flow path member, so that the exhaust flow passing through the exhaust flow path member reliably passes through the water film. Therefore, the adhesion effect of the dust and the liquid in the exhaust flow can be further improved.

一方の排気流路部材を排気流の方向と平行に配置し、他方の排気流路部材を排気流の方向と直交する方向に配置し、前記排気流路部材との間に混合室を形成する構成により、混合室内での排気流中の粉塵と液体の付着時間を増加させ、粉塵と液体の付着効果を向上することができる。   One exhaust passage member is arranged in parallel with the direction of the exhaust flow, the other exhaust passage member is arranged in a direction orthogonal to the direction of the exhaust flow, and a mixing chamber is formed between the exhaust passage member and the exhaust passage member. According to the configuration, it is possible to increase the adhesion time between the dust and the liquid in the exhaust flow in the mixing chamber and improve the adhesion effect between the dust and the liquid.

液体スプレイ噴霧装置の下流側に排気を乱流とする乱流生成手段を配置する構成により、排気流中の粉塵と液体の付着時間を増加させ、粉塵と液体の付着効果をより一層向上することができる。   By arranging the turbulent flow generation means that makes the exhaust gas turbulent downstream of the liquid spray spray device, the adhesion time of dust and liquid in the exhaust flow is increased, and the adhesion effect of dust and liquid is further improved. Can do.

次に、本発明を図示の実施形態により説明する。   Next, the present invention will be described with reference to the illustrated embodiments.

本発明の実施形態を図により説明する。図１（ａ）（ｂ）は、本発明の液体スプレイ噴霧装置を備えた除塵排気塔の実施例１を示すものである。除塵排気塔１は、発塵源のある工場等の建家の屋根２に形成された自然排気の換気口３に設置される。除塵排気塔１は、排気口３を区画する下部水平部４と、下部水平部４の排気口３側端部から垂直に低い高さで立ち上がる下部垂直部５と、下部水平部４の排気口３と反対側の端部から垂直に立ち上がる垂直壁部６と、垂直壁部６の上端から排気口３側に水平に延び、上部開口８を形成する上部水平屋根部７を有する。除塵排気塔１内には、上部開口８からの雨水の浸入するのを防ぐ中間水平屋根部９が設置される。除塵排気塔１内に、中間屋根部９の両端に固定される内部垂直隔壁１０と垂直壁部５により区画される排気通路１１が形成される。排気通路１１内に、少なくとも１個以上の断面円形又は矩形の排気流路部材１２を設置する。図１（ａ）（ｂ）に示される実施例１においては、排気流路部材１２は、排気通路１１内に排気流の方向と平行に配置する。排気通路１１には、排気流が排気流路部材１２内のみを流れるように遮蔽壁１３を設置する。排気流路部材１２内には、その排気流路部材１２の軸方向から見て円形の液体スプレイ噴霧装置１４が同心状に設置される。液体スプレイ噴霧装置１４のノズルから液体を排気流の方向又は排気流と反対方向に噴射する。排気流路部材１２に少なくとも液体スプレイ噴霧装置の液体スプレイ側に水膜生成用網１５を設置する。水膜生成用網１５は、排気流路部材１２の前後に複数枚設置してもよい。 An embodiment of the present invention will be described with reference to the drawings. 1 (a) and 1 (b) show Example 1 of a dust removal exhaust tower equipped with the liquid spray spray device of the present invention. The dust removal exhaust tower 1 is installed in a natural exhaust vent 3 formed on a roof 2 of a building such as a factory having a dust generation source. The dust removal exhaust tower 1 includes a lower horizontal portion 4 that defines an exhaust port 3, a lower vertical portion 5 that rises vertically from the end of the lower horizontal portion 4 on the exhaust port 3 side, and an exhaust port of the lower horizontal portion 4. 3 has a vertical wall portion 6 that rises vertically from an end opposite to the upper end 3, and an upper horizontal roof portion 7 that extends horizontally from the upper end of the vertical wall portion 6 toward the exhaust port 3 and forms an upper opening 8. An intermediate horizontal roof portion 9 is installed in the dust removal exhaust tower 1 to prevent rainwater from entering through the upper opening 8. In the dust removal exhaust tower 1, an exhaust passage 11 defined by an internal vertical partition wall 10 fixed to both ends of the intermediate roof portion 9 and the vertical wall portion 5 is formed. In the exhaust passage 11, at least one exhaust passage member 12 having a circular or rectangular cross section is installed. In the first embodiment shown in FIGS. 1A and 1B, the exhaust passage member 12 is disposed in the exhaust passage 11 in parallel with the direction of the exhaust flow. In the exhaust passage 11, a shielding wall 13 is installed so that the exhaust flow flows only in the exhaust passage member 12. A circular liquid spray spray device 14 is installed concentrically in the exhaust passage member 12 when viewed from the axial direction of the exhaust passage member 12 . The liquid is sprayed from the nozzle of the liquid spray sprayer 14 in the direction of the exhaust flow or in the direction opposite to the exhaust flow. A water film generating net 15 is installed in the exhaust passage member 12 at least on the liquid spray side of the liquid spray spraying device. A plurality of water film generation nets 15 may be installed before and after the exhaust passage member 12.

粉塵を含んだ排気流は、自然換気の上昇流となって建家の屋根２に形成された排気口３から除塵排気口１内に入る。除塵排気搭１内の排気流は、排気通路１１内に設置された排気流路部材１２内を流れる。排気流路部材１２内には、液体スプレイ噴霧装置１４と、液体スプレイ噴霧装置１４からの液体スプレイにより水膜を形成する水膜生成用網１５が設置されているので、狭い排気流路部材１２内を通過する排気流中の粉塵は、確実に液体と接触し、その見掛け比重を増大して排気流から分離され、除塵排気塔１の下部水平部４又は中間水平屋根部９上に落下し、粉塵を除去された排気流が除塵排気塔１の上部開口８から外部に排出される。 The exhaust flow containing dust enters the dust removal exhaust port 1 from the exhaust port 3 formed in the roof 2 of the building as an upward flow of natural ventilation. The exhaust flow in the dust removal exhaust tower 1 flows through the exhaust passage member 12 installed in the exhaust passage 11. In the exhaust flow path member 12, the liquid spray spray device 14 and the water film generation net 15 for forming a water film by the liquid spray from the liquid spray spray device 14 are installed. The dust in the exhaust stream passing through the interior reliably contacts the liquid, increases its apparent specific gravity and is separated from the exhaust stream, and falls on the lower horizontal portion 4 or the intermediate horizontal roof portion 9 of the dust removal exhaust tower 1. The exhaust stream from which the dust has been removed is discharged to the outside from the upper opening 8 of the dust removal exhaust tower 1.

図２（ａ）（ｂ）は、本発明の実施例２を示すものである。この実施例２においては、排気通路１１内に排気流路部材１２を上昇流として除塵排気塔１内に流入する排気流の方向と直交する方向、つまり水平に配置したものである。その他の構成は前記実施例１に示したものと同様である。排気流路部材１２を水平に配置する場合は、液体スプレイ噴霧装置１４から噴霧され、粉塵と結びついた液体が流れ落ちやすいように排気流の入口側が若干下側になるように傾けて配置する。   2 (a) and 2 (b) show Example 2 of the present invention. In the second embodiment, the exhaust passage member 12 is disposed in the exhaust passage 11 in a direction perpendicular to the direction of the exhaust flow flowing into the dust removal exhaust tower 1 as an upward flow, that is, horizontally. Other configurations are the same as those shown in the first embodiment. When the exhaust passage member 12 is disposed horizontally, the exhaust passage member 12 is inclined so that the inlet side of the exhaust flow is slightly lower so that the liquid sprayed from the liquid spray spraying device 14 and the liquid associated with the dust easily flows down.

図３（ａ）（ｂ）は、本発明の実施例３を示すものである。この実施例３においては、排気通路１１内に、排気流の方向と平行に排気流路部材１２を配置し、その下流側に排気流と直交する方向に排気流路部材１２を配置し、両排気流路部材１２，１２との間に遮蔽壁１３により閉ざされた混合室１６を形成する。その他の構成は前記実施例１、２に示したものと同様である。混合室１６内での排気流中の粉塵と液体の付着時間を増加させ、粉塵と液体との付着効果を向上させることができる。   3 (a) and 3 (b) show Example 3 of the present invention. In the third embodiment, the exhaust flow path member 12 is disposed in the exhaust passage 11 in parallel with the direction of the exhaust flow, and the exhaust flow path member 12 is disposed on the downstream side in a direction orthogonal to the exhaust flow. A mixing chamber 16 closed by a shielding wall 13 is formed between the exhaust flow path members 12 and 12. Other configurations are the same as those shown in the first and second embodiments. The adhesion time between the dust and the liquid in the exhaust flow in the mixing chamber 16 can be increased, and the adhesion effect between the dust and the liquid can be improved.

図４（ａ）（ｂ）は、本発明の実施例４を示すものである。この実施例４においては、前記実施形態３のように混合室１６を設けると共に、液体スプレイ噴霧装置１４が設置された排気流路部材１２の外側に、即ち液体スプレイ噴霧装置の下流側に、排気流の乱流形成手段として乱流生成板１７を配置する。排気通路１１内で排気流路部材１２の下流側に間隔をおいて排気流の方向と直角または傾斜して交差するように矩形等の乱流生成板１７が設けられる。その他の構成は前記実施例１、２に示したものと同様である。液体スプレイ噴霧装置１４の下流側に配置した乱流生成板１７に排気流が衝突することで乱流を生成することにより排気流中の粉塵と液体の付着時間を増加させ、粉塵と液体との付着効果を向上させることができる。   4 (a) and 4 (b) show Example 4 of the present invention. In Example 4, the mixing chamber 16 is provided as in the third embodiment, and the exhaust is provided outside the exhaust passage member 12 where the liquid spray spraying device 14 is installed, that is, downstream of the liquid spray spraying device. A turbulent flow generation plate 17 is disposed as a turbulent flow forming means. A turbulent flow generation plate 17 such as a rectangle is provided in the exhaust passage 11 so as to intersect with the direction of the exhaust flow at a right angle or inclined at a downstream side of the exhaust flow path member 12. Other configurations are the same as those shown in the first and second embodiments. The exhaust flow collides with the turbulent flow generation plate 17 disposed on the downstream side of the liquid spray spraying device 14 to generate a turbulent flow, thereby increasing the adhesion time of the dust and the liquid in the exhaust flow. The adhesion effect can be improved.

前記各実施形態では、屋根２に形成された自然換気の換気口３に、液体スプレイ噴霧装置を備えた除塵排気塔の形態を示したが、本発明を実施する場合、図示を省略するが、外壁に形成された自然換気の換気口に、前記各実施形態の液体スプレイ噴霧装置を備えた除塵排気塔を取付けるようにしてもよく、この場合には、外壁外側の排気ダクトの排気口部に下部水平部４を取り付けるようにすれば、前記各実施形態の除塵排気塔の姿勢を変えることなく取付けることができる。なお、必要に応じ、垂直壁部６を外壁に取り付けてもよい。   In each of the above embodiments, the form of the dust exhaust tower provided with the liquid spray spray device is shown in the natural ventilation vent 3 formed on the roof 2, but when the present invention is implemented, the illustration is omitted, A dust removal exhaust tower equipped with the liquid spray spray device of each of the above embodiments may be attached to a natural ventilation vent formed on the outer wall. In this case, the exhaust duct of the exhaust duct outside the outer wall may be attached. If the lower horizontal portion 4 is attached, it can be attached without changing the posture of the dust removal exhaust tower of each of the above embodiments. In addition, you may attach the vertical wall part 6 to an outer wall as needed.

また、本発明を実施する場合、屋根２または外壁の一方または両方に形成された自然換気の換気口に、前記各実施形態の液体スプレイ噴霧装置を備えた除塵排気塔を設けるようしてもよく、屋根２および外壁の両方の換気口に設けると、一方に設ける場合に比べて室内の粉塵除去処理を高めることができる。   Moreover, when implementing this invention, you may make it provide the dust removal exhaust tower provided with the liquid spray spray apparatus of each said embodiment in the ventilation opening of the natural ventilation formed in one or both of the roof 2 or the outer wall. If it is provided in the ventilation openings on both the roof 2 and the outer wall, the dust removal treatment in the room can be enhanced as compared with the case where it is provided on one side.
