内に換気流を送入する方法が採られている。<Prior Art> Conventionally, ventilation in a room is performed by fitting a ventilation device including a fan and a filter to an exhaust port or sending a ventilation flow into the room from a ventilation device installed outdoors.
＜発明が解決しようとする課題＞ しかしながら、上記したいずれの換気器具、装置も火山

くなるという課題がある。<Problems to be Solved by the Invention> However, in any of the above-described ventilation equipment and devices, in a volcanic ash fall area, the filter is clogged in a short period of time and it is difficult to send clean air from which ash dust has been removed into the room. There is a problem.

給気パイプの一端を挿着し、主パイプおよび吸込パイプ
を屋外に設置して室内換気をするようにしたのである。<Means for Solving the Problems> According to the present invention, a cylindrical main pipe having at least one side closed and an air supply pipe connected to the other side of the main pipe, and an outer end protruding to the closed one side of the main pipe. , A suction pipe having a diameter smaller than that of the main pipe inserted so that the inner end is located at an intermediate portion in the main pipe, and a diameter smaller than that of the suction pipe for improving the flow velocity of the air sucked into the inner end of the suction pipe. The formed bifurcated outlet is provided, and the outlet air is inclined and twisted toward the closed side of the main pipe so that the outflowing atmosphere swirls in the main pipe and descends. A ventilation pipe filter was constructed, one end of the air supply pipe was inserted into the ventilation port of the building, and the main pipe and suction pipe were installed outdoors for indoor ventilation.
＜作 用＞ 本発明は換気口に設けた室内ファンを排気側に回転する
と、ファンの遠近にかかわらず給気パイプ内に給気流が
流れて接続する主パイプを経て吸込パイプより等量の大
気が吸込まれる。<Operation> When the indoor fan provided at the ventilation port is rotated to the exhaust side, the present invention passes through the main pipe through which the air supply flows into the air supply pipe regardless of the distance between the fan and the atmosphere, and the same amount of atmospheric air as that of the suction pipe. Is sucked.
この吸込大気は２つの流出口より主パイプ内に吸入され
ることとなるが、流出口は吸込パイプより二股に分岐し
て且つ細く絞られて主パイプの閉塞方向に傾斜捻曲して
いることによって、重力、遠心力、慣性力の３つの作用
が有効に働いて吸込大気中に含まれる灰塵の殆んどを除
去し、上澄のきれいな吸込大気のみを吸気口より室内に
供給することとなる。This suction atmosphere is sucked into the main pipe through the two outlets, but the outlet is bifurcated from the suction pipe and is narrowed down so that it is inclined and twisted in the closing direction of the main pipe. The three functions of gravity, centrifugal force, and inertial force effectively work to remove most of the ash dust contained in the intake air, and only the clean intake air of the supernatant is supplied to the room through the intake port. Become.
すなわち、主パイプの閉塞方向に傾斜捻回した小径の流
出口より流出する大気は主パイプの側壁内面に鈍角にて
衝突するまでは流速が大きく、その後大径の主パイプ内
を渦巻状となって主パイプの閉塞方向に降下流動するこ
とにより吸込大気中に含まれる灰塵粒子は重力、遠心力
及び慣性作用を受けて主パイプの非給気側に押しやられ
て、上澄のきれいな吸込大気のみが給気パイプより室内
に供給されることとなる。That is, the air flowing out from the small-diameter outlet that is inclined and twisted in the closing direction of the main pipe has a large flow velocity until it collides with the inner surface of the side wall of the main pipe at an obtuse angle, and then becomes a spiral in the large-diameter main pipe. The ash dust particles contained in the suction atmosphere as a result of downward flow in the closing direction of the main pipe are pushed to the non-air supply side of the main pipe by gravity, centrifugal force and inertial action, and only the suction air with a clean supernatant Will be supplied indoors through the air supply pipe.
つまり衝突直前の流速が大きく、その後流速が弱まるこ
とから集塵率が高くなるのである。また吸込大気は二股
部分と主パイプ内面の２回に亘り衝突反転することによ
り灰塵捕集慣性力が高くなる。In other words, the flow velocity immediately before the collision is high, and then the flow velocity weakens, so the dust collection rate increases. Further, the suction atmosphere is subjected to collision reversal twice, that is, the forked portion and the inner surface of the main pipe, so that the ash dust collecting inertial force becomes high.

いる。1 and 2 show the first embodiment, in which the air supply pipe 3 is attached to one outer wall 2a surrounding the room 1 of the building so as to project downward from the outer wall 2a of the air supply pipe 3. The main pipe 4 is vertically connected to the bent portion. 4a is a removable cap at the lower end. A suction pipe 5 having a diameter smaller than that of the main pipe 4 is attached to the lower side surface of the main pipe 4 with a penetrating portion. Reference numeral 5a is a suction port, and 6a and 6b are outlets having a diameter smaller than that of the suction pipe 5 which is bifurcated at a position on the middle of the main pipe 4 and is bent obliquely downward (about 45 degrees). . When the indoor fan 8 of the exhaust port 7 of the other side wall 2b of the room is operated to the exhaust side,
A slack air supply flows in the air supply pipe 3, and the air is sucked in through the suction port 5a of the suction pipe 5, and the sucked air is accelerated at the narrow bifurcated portion and twisted diagonally downward while reversing the collision. It flows out into the main pipe 4 through the curved outlets 6a, 6b, hits the inside surface of the side wall of the main pipe 4 at an obtuse angle, and forms a vortex of a slow flow that descends to drop ash dust onto the cap 4a at the lower end of the main pipe 4. Only the clean clean air is supplied to the room through the air supply pipe 3, and the accumulated ash dust is removed by removing the cap 4a. FIG. 3 is the same as the first embodiment except that the air supply pipe 3 is made thinner than the main pipe 4, FIG. 4 is an example in which an indoor fan 8 is attached to the air supply port 9, and FIG. An example of horizontally extending the pipe 4 is shown.

とができるという効果を生ずる。<Effects of the Invention> As described above, according to the present invention, the suction pipe has a smaller diameter than the main pipe, and the suction pipe has a smaller diameter than the suction pipe in order to improve the flow velocity of the air by sucking the inflow outlet of the main pipe. Since it was bifurcated and inclined and twisted toward the closed side of the main pipe, the intake air acceleratedly flowed into the main pipe from the outlet of the forked pipe, colliding and reversing against the inner surface of the side wall of the main pipe. Due to the wide diameter of the main pipe, it slows down to a slow vortex and descends in the closing direction in the main pipe, that is, the flow velocity immediately before the collision is high, and then the flow velocity weakens, so the dust collection rate becomes high, and the suction atmosphere has a bifurcated part. By colliding and reversing the inner surface of the main pipe twice, the ash dust collecting inertial force becomes high and even if the atmosphere containing a large amount of ash dust is sucked into the main pipe, gravity, centrifugal force and inertial action are effective. Action As a result, the included ash dust can be reliably separated and removed, and only the clean, clear air can be supplied to the room through the air supply pipe.
本発明パイプフィルターはまた塗装工場、研磨室等に設
置して、不純物を有効に除去することができるという効
果を生ずる。The pipe filter of the present invention can also be installed in a coating factory, a polishing room, etc., so that impurities can be effectively removed.
さらに本発明は主パイプ、吸込パイプ、給気パイプにて
構成して、フィルターに類するものが介在しないことに
より、目詰まりが全く生じないという効果を生ずる。Further, the present invention has an effect that clogging does not occur at all because the main pipe, the suction pipe, and the air supply pipe are used and no filter-like member is interposed.
