(57) [Summary] [Purpose] Improvement of the device that causes nuclear condensation of water vapor around fine particles floating in the air to form coarse water droplets for separation and removal. [Structure] The low-temperature wet steam (12) is introduced into the cylindrical container (21) from the upper part, and the high-temperature wet steam (11) is introduced from the lower part thereof in the tangential direction to efficiently perform adiabatic mixing. Since the mixed air flow swirls along the inner wall surface of the container, fine particles (1
The water droplets (16) that have taken in 5) and the like and have undergone nuclear condensation collide with the inner wall surface of the container by centrifugal force, flow down along the wall surface, and are discharged and collected from the drain port (25). The clean air (9) from which pollutants have been removed is discharged from an exhaust pipe (22) arranged in the center of the container (21). According to the present invention, since nuclear condensation and water drop collection are performed at the same time, it is possible to reduce the size of the entire equipment without the need for a conventional filter or the like.
Description
【０００１】[0001]
本考案は、クリーンルームや一般空調室等の閉鎖空間内の空気清浄設備におい て微粒子等を分離除去する装置に関する。 The present invention relates to an apparatus for separating and removing fine particles and the like in an air cleaning facility in a closed space such as a clean room or a general air conditioning room.

図５は従来の空気清浄設備の一例を示す全体概念図、図６は図５中の核凝縮発 生器を示す詳細図である。 FIG. 5 is an overall conceptual diagram showing an example of conventional air cleaning equipment, and FIG. 6 is a detailed diagram showing the nuclear condensation generator in FIG.
【０００３】 まず図５において、微粒子またはガス状物質を含んだクリーンルーム内の汚染 空気１は、ファン２により配管３を通って分配器４へ送られ、ここで２方向に分 配される。その一方は加温加湿器５へ送られて高温湿り空気となり、他方は冷却 器６へ送られて低温湿り空気となる。これら高温および低温の湿り空気は、それ ぞれ、後流の核凝縮発生器７へ入る。First, in FIG. 5, contaminated air 1 in a clean room containing fine particles or gaseous substances is sent by a fan 2 through a pipe 3 to a distributor 4, where it is distributed in two directions. One of them is sent to the warming / humidifying device 5 to become high temperature humid air, and the other is sent to the cooler 6 to become low temperature humid air. The hot and cold humid air enters the downstream condensing generator 7, respectively.
【０００４】 核凝縮発生器７においては、図６に示されるように、上方から微粒子またはガ ス状物質１５を含んだ高温湿り空気１１が高温側吸気口１３を通って器内へ吹き 込まれ、下方からは同様に微粒子またはガス状物質１５を含んだ低温湿り空気１ ２が低温側吸気口１４を通って器内へ吹き込まれる。吹き込まれた両湿り空気は 核凝縮発生器７内で衝突して断熱混合する。これによって微粒子またはガス状物 質１５を核とする水蒸気の核凝縮が起こり、除去可能な大きさの粒子径に成長す る。そして、このような粒子（水滴）１６を含む空気が排気口１０から器外へ排 出されると、図５に示される下流のフィルタ８によって汚染粒子が除去され、清 浄空気９が得られるようになっている。In the nuclear condensation generator 7, as shown in FIG. 6, high temperature moist air 11 containing fine particles or a gas-like substance 15 is blown into the chamber from a high temperature side intake port 13 from above. From below, low-temperature humid air 12 containing fine particles or a gaseous substance 15 is blown into the container through the low-temperature side intake port 14. Both of the moist air blown into each other collide in the nuclear condensation generator 7 and are adiabatically mixed. As a result, nuclear condensation of water vapor with the fine particles or the gaseous substance 15 as a nucleus occurs, and the particle diameter grows to a removable size. Then, when the air containing such particles (water droplets) 16 is discharged from the exhaust port 10 to the outside of the device, the downstream filter 8 shown in FIG. 5 removes the contaminating particles and the purified air 9 is obtained. It has become.
【０００５】[0005]
前記従来の核凝縮発生器７では、次のような不具合点があった。すなわち、核 凝縮した水滴は核凝縮発生器では捕集できないから、下流にフィルタ８等を設け て捕集しなければならなかった。そのため、設備全体として大きいものになって いた。 The conventional nuclear condensation generator 7 has the following drawbacks. In other words, the water droplets that have been condensed by the nucleus cannot be collected by the nuclear condensation generator, so a filter 8 or the like must be provided downstream to collect them. Therefore, the equipment as a whole was large.

本考案は、前記従来の課題を解決するために、竪型円筒状の容器と、同容器の 側面上部に接線方向に開口する低温湿り空気導入管と、同低温湿り空気導入管よ りも下方で上記容器の側面に接線方向に開口する高温湿り空気導入管と、上記容 器の軸線に沿って配され下端が上記高温湿り空気導入管よりも下方で上記容器内 に開口する清浄空気排出管と、上記容器の底部に開口する凝縮水滴排出管とを具 備したことを特徴とする微粒子分離除去装置を提案するものである。 In order to solve the above-mentioned conventional problems, the present invention proposes a vertical cylindrical container, a low temperature humid air introduction pipe tangentially opening at the upper side of the container, and a lower temperature lower than the low temperature humid air introduction pipe. A tangentially open high temperature humid air inlet pipe to the side of the container, and a clean air exhaust pipe that is located along the axis of the container and has a lower end that opens below the high temperature humid air inlet pipe into the container. And a condensed water droplet discharge pipe which is opened at the bottom of the container.
【０００７】[0007]
上記本考案の微粒子分離除去装置は以下の作用を有する。 １） 容器の上部から低温湿り空気が、その下方から高温湿り空気が、それぞれ 吹き込まれるので、密度の大きい低温湿り空気は下方へ下降し、密度の小さい高 温湿り空気は上方へ上昇して、効率よく断熱混合が行なわれる。 ２） 低温湿り空気導入管と高温湿り空気導入管は、いずれも容器側面に接線方 向に開口しているので、容器内の混合気流は器内壁面に沿って旋回運動を行なう 。したがって微粒子またはガス状物質を取り込んで核凝縮した水滴は、自重によ る遠心力によって器内壁面に衝突し、壁面を伝わって容器底部へ流下してゆき、 凝縮水滴排出管から排出・捕集される。 The device for separating and removing fine particles of the present invention has the following effects. 1) Low-temperature moist air is blown from the upper part of the container, and high-temperature moist air is blown from the lower part of the container, so that the low-temperature moist air having a high density descends downward, and the high-temperature moist air having a low density rises upward, Adiabatic mixing is efficiently performed. 2) Both the low temperature humid air introduction pipe and the high temperature humid air introduction pipe are opened tangentially to the side of the container, so that the mixed air flow in the container makes a swirling motion along the inner wall surface of the container. Therefore, the water droplets that have taken in fine particles or gaseous substances and have undergone nuclear condensation collide with the inner wall surface due to the centrifugal force due to their own weight, travel along the wall surface and flow down to the bottom of the container, and are discharged and collected from the condensed water droplet discharge pipe. To be done.
【０００８】 ３） 一方汚染物質を除去された清浄空気は、容器中央の軸線に沿って配された 清浄空気排出管から器外へ排気される。またこの清浄空気排気管の開口部は、高 温湿り空気導入管よりも下方に位置しているので、高温湿り空気が清浄空気排気 管へ直接侵入することはない。 ４） 本考案においては、微粒子分離除去装置だけで核凝縮と凝縮水滴の捕集が 同時にできるので、フィルタ等を必要とせず、設備全体をコンパクトにできる。3) On the other hand, the clean air from which contaminants have been removed is exhausted out of the device through a clean air discharge pipe arranged along the axis of the center of the container. Further, since the opening of the clean air exhaust pipe is located below the high temperature / humidity air introduction pipe, the high temperature / humidity air does not directly enter the clean air exhaust pipe. 4) In the present invention, since the nuclear condensation and the collection of condensed water droplets can be performed simultaneously with only the fine particle separation and removal device, no filter or the like is required, and the entire equipment can be made compact.

図１は本考案の第１実施例を示す平面図，図２は同じく側面図である。本実施 例では、竪型円筒状の容器２１の側面上部に低温湿り空気導入管２４が、その下 方の同じく側面に高温湿り空気導入管２３が、いずれも接線方向にそれぞれ開口 している。また容器２１の中央部には、軸線に沿って清浄空気排出管２２が配さ れ、その開口部（排気口）２２ａは、高温湿り空気導入管２３よりも低位置にあ る。更に容器２１の底部は逆円錘形をしており、凝縮水滴排出管２５が開口して いる。 1 is a plan view showing a first embodiment of the present invention, and FIG. 2 is a side view of the same. In this embodiment, a low temperature humid air introduction pipe 24 is opened in the upper side surface of the vertical cylindrical container 21, and a high temperature humid air introduction pipe 23 is also opened tangentially in the lower side surface thereof. A clean air discharge pipe 22 is arranged along the axis in the center of the container 21, and its opening (exhaust port) 22 a is located lower than the hot and humid air introduction pipe 23. Further, the bottom of the container 21 has an inverted conical shape, and the condensed water droplet discharge pipe 25 is opened.
【００１０】 低温湿り空気導入管２４から流入してきた微粒子またはガス状物質１５を含む 低温湿り空気１２は、容器２１の壁面に沿って旋回しながら下方へ流れてゆく。 一方高温湿り空気導入管２３から流入してきた微粒子またはガス状物質１５を含 む高温湿り空気１１は同様に旋回しながら上方へ流れてゆく。両湿り空気は途中 で出遇い、混合しながら旋回する間に、微粒子またはガス状物質１５を核とする 水蒸気の核凝縮が起こる。生成された凝縮水滴１６は、旋回の遠心力により容器 ２１の壁面に衝突して捕捉され、壁面に沿って降下し、凝縮水滴排出管２５から 器外へ排出される。一方、微粒子またはガス状物質１５を除去された清浄空気９ は、容器中央の清浄空気排出管２２を通って器外へ排出される。なお、この実施 例における高温側および低温側の湿り空気導入管２３，２４の位置関係は、同じ 旋回方向であれば、相対的に３６０°どの位置に開口部があってもよい。The low-temperature humid air 12 containing the fine particles or the gaseous substance 15 flowing in from the low-temperature humid air introduction pipe 24 flows downward while swirling along the wall surface of the container 21. On the other hand, the high-temperature humid air 11 containing the fine particles or the gaseous substance 15 flowing in from the high-temperature humid air introduction pipe 23 similarly swirls and flows upward. Both humid air are treated on the way, and while swirling while mixing, nuclear condensation of water vapor with the fine particles or the gaseous substance 15 as the nucleus occurs. The generated condensed water droplets 16 collide with and are captured by the wall surface of the container 21 by the centrifugal force of the swirl, fall along the wall surface, and are discharged from the condensed water droplet discharge pipe 25 to the outside of the device. On the other hand, the clean air 9 from which the fine particles or the gaseous substance 15 has been removed is discharged to the outside of the device through the clean air discharge pipe 22 at the center of the container. In this embodiment, the high temperature side and the low temperature side of the humid air introducing pipes 23 and 24 may have an opening portion at any relative position of 360 ° as long as they have the same turning direction.
【００１１】 図３および図４は、本考案の第２実施例として、高温および低温の湿り空気１ １，１２の旋回方向が反対になるように、高温湿り空気導入管３３と低温湿り空 気導入管３４を配置した例を示す平面図および側面図であり、作用効果は前記第 １実施例と同じである。本実施例においても、高温側および低温側の湿り空気導 入管３３，３４の位置関係は、相対的に３６０°どの位置にあってもよい。3 and 4 show a second embodiment of the present invention, in which the hot and cold humid air introduction pipes 33 and the cold humid air are arranged so that the swirling directions of the hot and cold humid air 11 and 12 are opposite to each other. It is a top view and a side view showing an example in which introduction pipe 34 is arranged, and the operation and effect are the same as those in the first embodiment. Also in the present embodiment, the positional relationship between the high temperature side and the low temperature side humid air introducing pipes 33, 34 may be at any relative position of 360 °.
【００１２】[0012]
本考案の微粒子分離除去装置によれば、次に示す効果が得られる。 １） 密度の大きい低温湿り空気が上方から、密度の小さい高温湿り空気が下方 から、それぞれ流入するので、両者の断熱混合が効率よく行なわれる。 ２） 核凝縮した水滴は自重による遠心力のため該容器側面に衝突・捕集され、 清浄空気と分離される。 ３） 核凝縮の発生と凝縮水滴の捕集を同時に行なうので、設備全体をコンパク ト化できる。 According to the particulate separation and removal device of the present invention, the following effects can be obtained. 1) Since low-temperature moist air having a high density flows in from above and high-temperature moist air having a low density flows in from below, adiabatic mixing of both is efficiently performed. 2) The condensed water droplets collide and are collected on the side surface of the container due to the centrifugal force due to its own weight, and are separated from the clean air. 3) Since the nuclear condensation occurs and the condensed water droplets are collected at the same time, the entire equipment can be compacted.
