Description

  The present invention relates to a dehumidifying device for dehumidifying a space such as a room and an air cleaner to which the dehumidifying device is applied.

  Conventionally, it has been attempted to treat dirty air in a office room, an amusement facility, a factory or the like using an air purifier. As an example, for example, non-processed air taken in from an intake port is brought into contact with a liquid such as water or a cleaning liquid in a spray cooler (capturing unit), and tobacco smoke or dust contained in the non-processed air. Alternatively, after trapping contaminants and removing dust, untreated air that has been excessively humidified with liquid fine particles is guided to the inside through the inlet of a cyclone (dehumidifier), and the centrifugal force of the cyclone An air purifier has been developed in which liquid contained in untreated air is separated and dehumidified, and then the treated air is sent out from the cyclone outlet by an updraft generated near the center axis of the cyclone. The liquid separated from the untreated air is discharged to the outside of the cyclone through a drain extending from the bottom of the cyclone (see, for example, Patent Document 1).

  When the operation of the air purifier 1 shown in FIG. 2 is started, the fan 5 is activated and the air P in the room 50 described above is taken into the air purifier 1 from the intake port 2a. 5 flows out into the space between the dust removing section 13 and the storage section 14 on the lower side of the capturing device 3 through the outlet 5a. At this time, since the liquid in the tank 6 is supplied to the spray unit 12 via the supply pump 7 and sprayed toward the dust removing unit 13 on the lower side, the air P that has flowed into the capture device 3 flows into the capture device 3. The liquid P is intermittently contacted, fine particles such as fine dust and tobacco dust contained in the air P are captured by the liquid, and the air P is washed. In addition, liquid (hereinafter referred to as waste liquid E) that captures dust, tobacco dust, or the like flows down to the storage unit 14 and is temporarily stored, and then flows to the recovery pump 16 through the connection pipe 15.

  Next, the dehumidifying device 4 will be described. As shown in FIGS. 4 to 6, the dehumidifying device 4 includes a cylindrical body 40 having a bottom surface 40 c and an inlet duct 42 having the inlet 42 a of the dehumidifying device 4 described above. And an exhaust pipe 41 having an outlet 41a extending from the upper end surface 40a of the cylindrical body 40 so as to partially penetrate into the cylindrical body 40. The cylindrical body 40 has a cylindrical inner cavity structure having a long axial length compared to the length of the diameter, and is disposed vertically long. The cylindrical body 40 has a bottom surface 40c side facing toward the bottom surface 40c. A reduced diameter portion 40d that gradually decreases in diameter is formed, and a same diameter portion 40b that extends to the same diameter in the vertical direction is formed on the inlet duct 42 side. Further, the intrusion direction of the inlet duct 42 extends so as to remove the central axis of the cylindrical body 40 as shown in FIG. 5, and the cylinder is in contrast to the cleaned air P ′ introduced from the inlet duct 42. The swirl flow is generated so as to turn around the exhaust pipe 41 extending into the body 40. In particular, in this embodiment, as shown in FIG. 5, the cross-sectional shape of the inlet duct 42 is rectangular, and the outer surface 42 c is along the tangential direction of the inner peripheral surface 40 g of the same diameter portion 40 b of the cylindrical body 40. It is arranged to extend. For this reason, the cleaned air P ′ entering from the inlet duct 42 is guided to the inner peripheral surface 40 g of the cylindrical body 40 without resistance, and an effective swirling flow can be generated.

  As shown in FIG. 4 to FIG. 7, a slit 20 as a lead-out port communicating with the inside and the outside of the cylindrical body 40 is formed at a predetermined position on the peripheral surface of the reduced diameter portion 40 d. Is provided with a long side portion 20 a in the axial direction of the cylindrical body 40 and is shortened in the circumferential direction of the cylindrical body 40. Also, as shown in FIGS. 4 to 7, the opening end of the slit 20 is formed flush with the inner peripheral surface 40 g of the tubular body 40. In this embodiment, the slit 20 is opened at one place on the peripheral surface of the cylindrical body 40, but the present invention is not limited to this, and the outlet of the present invention is provided at two locations as long as the peripheral surface of the cylindrical body 40. You may open above.

  As shown in FIGS. 4 to 7, a discharge chamber 21 is provided on the outer peripheral surface of the reduced diameter portion 40d so as to surround the slit 20, and the discharge chamber 21 and the inside of the cylindrical body 40 are slit. 20 to communicate with each other. In addition, the discharge chamber 21 communicates with the connection pipe 15 described above. Although not particularly shown here, an auto drain, an electromagnetic valve, or the like may be provided between the discharge chamber 21 and the connection pipe 15.

  Furthermore, an opening 40e is provided in the bottom surface 40c of the cylindrical body 40, and a discharge pipe 10 'capable of discharging a fluid is connected to the outside of the air cleaner 1. Further, the communication passage communicating with the outside through the opening 40e can be opened and closed by a motor valve 11 'disposed at a predetermined position of the discharge pipe 10'.

  As shown in FIGS. 2 and 6, the cleaned air P ′ cleaned in the capturing device 3 flows into the duct 17 in a state of being humidified with some of the fine particles of the waste liquid E. The cleaned air P ′ flowing into the duct 17 flows from the upper end of the cylindrical body 40 into the dehumidifying device 4 through the inlet 42a in the tangential direction of the inner peripheral surface 40g of the cylindrical body 40. Then, it flows down toward the bottom surface 40 c while turning along the inner peripheral surface 40 g of the cylindrical body 40. As shown in FIGS. 6 and 7, the air P ′ after the cleaning has a specific gravity from the air P ′ after the cleaning due to the centrifugal force generated when swirling along the inner peripheral surface 40 g of the cylindrical body 40. A large waste liquid E is separated in the outer diameter direction and dehumidified.

  When the cleaned air P ′ swirling along the inner peripheral surface 40g of the cylindrical body 40 reaches the vicinity of the bottom surface 40c, the treated air D from which the waste liquid E is separated and dehumidified becomes the substantially central axis of the swirling flow. In this direction, the air P ′ rises through the inside of the swirling flow of the cleaned air P ′, and a part of the treated air D that has risen is discharged from the outlet 41a and returned to the chamber 50 described above. .

  As shown in FIGS. 6, 7, and 8, when the waste liquid E swirling along the inner peripheral surface 40 g of the cylindrical body 40 reaches the reduced diameter portion 40 d, its turning radius decreases as it goes downward. The rotational angular velocity of the swirling flow of the waste liquid E increases. Therefore, the waste liquid E that flows down while turning toward the bottom surface 40c of the cylindrical body 40 reaches the position of the slit 20 with the rotational speed of the swirling flow increased, and the waste liquid E slits using the centrifugal force. 20 is vigorously discharged into the discharge chamber 21 through 20. Therefore, only the waste liquid E adhering to the inner peripheral surface 40g of the cylindrical body 40 by centrifugal force can be gradually and continuously discharged without excessively retaining the waste liquid E in the cylindrical body 40. Therefore, the dehumidifier 4 can be operated continuously, and the entire air cleaner 1 can be operated continuously.

  As described above, by providing the slit 20 on the peripheral surface of the reduced diameter portion 40d where the diameter of the cylindrical body 40 is gradually reduced, the rotational angular velocity of the waste liquid E turning around the reduced diameter portion 40d can be increased. Can compensate for the pressure loss due to friction with the inner peripheral surface 40g of the cylindrical body 40 and the stalled portion of the swirling flow caused by being discharged from the slit 20, and the deterioration of the function of separating the waste liquid E can be prevented. The

  Next, a first modification of the outlet is described with reference to FIG. In addition, the description which overlaps with the same structure as the said Example is abbreviate | omitted. The lead-out port 201 in this modification is configured by an opening 201a formed in the circumferential surface of the reduced diameter portion 40d of the cylindrical body 40, and a pipe 201b attached in a sealed manner to the opening 201a. The end surface 201c on the side of the pipe 201b attached to the opening 201a is formed to be inclined with respect to the tube axis of the pipe 201b, and a part of the end surface 201c protrudes into the cylindrical body 40, and the pipe 201b. Is opposed to the swirl direction of the waste liquid E. Further, the end on the opposite side of the end face 201c communicates with the connecting pipe 15 described above (not shown).

  With the above configuration, a part of the swirling flow of the waste liquid E swirling in the cylindrical body 40 is changed in flow by a part of the end surface 201c slightly protruding into the cylindrical body 40, and the end of the pipe 201b From the opening, it is guided to the connecting pipe 15 through the pipe 201b. In this way, it is only necessary that the swirl flow of the waste liquid E swirling in the cylindrical body can be led out of the cylindrical body using the centrifugal force.

  In this modification, the description has been made on the assumption that the opening 201a has a substantially circular shape and the pipe 201b has a substantially cylindrical shape. However, for example, it is configured by a slit-like opening and a pipe that fits the slit-like opening. Something may be used. For example, a guide fin or the like that protrudes toward the central axis of the cylindrical body with respect to the inner peripheral surface of the cylindrical body near the outlet may be provided.

  Next, a second modification of the outlet will be described with reference to FIG. As shown in FIG. 10, the slit 202 of the present modification is formed to be inclined so that the swivel downstream opening surface 202 a of the waste liquid E gradually spreads toward the outer peripheral surface side of the tubular body 40. Therefore, the discharge flow E2 separated from the swirling flow of the waste liquid E through the slit 202 is smoothly discharged out of the cylindrical body 40 along the inner side surface 202a.

  Next, an example of the opening degree adjusting means and the opening position adjusting means of the present invention will be described with reference to FIGS. In addition, the description which overlaps with the same structure as the said Example is abbreviate | omitted. As shown in FIG. 11, the cylindrical body 401 has guides 80, 80 extending from the edges of both sides in the circumferential direction of the slit 200 toward the outer diameter direction of the cylindrical body 401, and the discharge chamber 210. A screw hole 210b that opens to face the slit 200 is disposed in the vertical direction on the surface 210a facing the slit 200, and a bolt 61 is screwed into the screw hole 210b and sealed through a bearing 62. The body 63 can be inserted into and removed from the slit 200. By these mechanisms, an opening degree adjusting means and an opening position adjusting means in the slit 200 are configured. The sealing body 63 is preferably made of a material such as rubber or synthetic resin that has some elasticity but also has rigidity, but may be made of a rust-resistant metal such as stainless steel. Further, as shown in FIG. 12, the surface on the slit 200 side of the sealing body 63 is provided with a curved portion 63 a that curves along the inner peripheral surface 401 g of the cylindrical body 401.

  The opening degree adjusting means and the opening position adjusting means in the slit 200 described above will be described in detail. When a predetermined tool is engaged with the bolt 61 from the outside of the discharge chamber 210 and is rotated, as shown in FIGS. In addition, the sealing body 63 moves toward the slit 200. At this time, the bolt 61 rotates in the axial direction. However, since the bolt 61 is fixed to the sealing body 63 via the bearing 62, the sealing body 63 is slid with its rotation regulated by the guides 80 and 80. While moving toward the slit 200, the sealing body 63 can be easily fitted into the slit 200 in a sealed manner. In addition, when the sealing body 63 is fitted in the slit 200 in a sealing manner, the curved portion 63a is flush with the inner peripheral surface 401g of the cylindrical body 401. The flow of the waste liquid E swirling on the surface 401g is not hindered.

  As shown in FIG. 11, for example, when the lower end portion of the slit 200 is sealed in a sealed manner by the lowermost sealing body 63, the opening area of the slit 200 becomes small as shown in FIG. 13A. . Further, when the upper end portion of the slit 200 is sealed in a sealed manner by the uppermost sealing body 63 from the state of FIG. 13A, the opening area of the slit 200 is further reduced as shown in FIG. 13B. Will be formed.

  For example, as shown in FIG. 13 (c), a part of the slit 200 is hermetically sealed by the respective sealing bodies 63, so that the opening area of the slit 200 is only at the upper end of the slit 200. The position of the slit 200 can be adjusted as appropriate.

  The adjustment means in the present modification is an aspect in which a plurality of adjustment means are provided in the vertical direction, but in an aspect in which a plurality of adjustment means are provided in the circumferential direction of the cylindrical body and the circumferential width of the opening region of the outlet is adjustable It is also possible to combine the above two aspects.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.

  For example, in the above embodiment, the air purifier 1 takes in the air P in the room 50 and cleans it, dehumidifies the air P ′ after washing, and sends it to the room 50 to clean the room air. For example, the outside air outside is taken in and washed, the air P ′ after washing is dehumidified, and the treated air D is sent into the room 50 to dilute the dirty air P in the room 50 with the treated air D. The indoor air may be cleaned.

  Moreover, in the said Example, although the aspect where the dehumidification apparatus 4 was used for the air cleaner 1 was demonstrated, not only this but a dehumidification apparatus may be used independently, for example, in order to dehumidify indoor air. However, it may be incorporated in a part of a machine tool or the like that uses liquid. Further, for example, the processed air dehumidified by the dehumidifying device may be taken into an air conditioner or the like to adjust the temperature of the processed air as appropriate.

  In addition, the dehumidifier 4 includes an opening 40e that can be opened and closed by the motor valve 11 ′ on the bottom surface 40c of the cylindrical body 40. For example, the opening is not particularly provided on the bottom surface, and the lower end of the peripheral surface of the cylindrical body A lead-out port may be provided in a part of the circumferential direction, and the entire amount of waste liquid accumulated in the cylindrical body at the lead-out port may be discharged. According to this, during operation of the dehumidifier, waste liquid is discharged from the outlet through centrifugal force, and when the dehumidifier is stopped, the waste liquid is discharged from the outlet through the weight of the waste liquid.

  In addition, the outlet of the present invention is not limited to the above-described slit shape, and the slit may be inclined, or may be freely set as appropriate in a circular shape, an arc shape, or the like. Moreover, you may provide in the arbitrary positions in the surrounding surface of a cylindrical body.
