Definitions
- An air humidifier including an element comprised of a core provided with spaced radially extending bristles which function as an evaporative surface upon being rotated between a water sump and a stream of air.
- This invention relates to gas and liquid contact apparatus and particularly air humidifier apparatus adapted v the air stream where they form a fine dust which has been found to be particularly undesirable.
- the instant invention relates to the former type of rotary humidifier which relies upon evaporation of water from a rotating wetted surface wherein the minerals entrained within the water are retained on such surface and prevented from contaminating the air.
- this type of air humidifier has presented two basic problems.
- the instant invention is directed toward a humidifier combination which has for its principal object the provision of a device which is high in surface area, extremely easy to clean, simple in construction, easy to manufacture, and low in cost.
- the instant invention comprises in combination means defining a water sump, an elongated bristle supporting core having a generally horizontal axis, support means supporting said elongated core above the normal water level in said sump for rotation about said 'axis, a plurality of elongated bristles supported by and extending radially outward from said core, said bristles being spaced longitudinally along and circumferentially about a portion of said core, each of said bristles being supported solely at its inner portion whereby the radially outer portion is permitted to flex, said support means being arranged with respect to said sump for movement of the radially outer portion of said bristles sequentially into and out of said water sump upon rotation of said core, motor means for rotating said core, and means for passing 'a stream of air over said bristles which are disposed out of said sump as said core is rotated whereby water adhering to said bristles is vaporized into said stream of air.
- FIGURE 1 shows my novel humidifier applied to a hot air furnace installation
- FIGURE 2 shows an enlarged end View of the humidifier in FIGURE 1 having an end cover removed for disclosure of details thereof;
- FIGURE 3 is a sectional view taken at line 3-3 in FIGURE 2;
- FIGURE 4 is an enlarged axial section of the rotatable liquid-gas contact member of the humidifier of FIG- U-RES 1-3.
- furnace 10 is provided with a cold air return duct 12 and a hot air supply duct 14.
- Humidifier .16 is mounted on duct 14 and receives warm air therefrom through an inlet opening 18 and discharges humidified air from an outlet opening 20 at one end thereof through a duct 22 into the return duct 12.
- Humidifier .16 includes a rectangular vaporizing chamher or housing 24 having a top wall 26, a first end wall 28, a second end wall 30 defining outlet 20, and a removable front wall 32.
- the back side of chamber 24 is fastened by screws 29 to duct 14 and closed by the wall of duct 14 except for inlet opening 18.
- a water receiving sump 34 having a semicylindrical pan portion '36 provided with first and second vertically extending end walls 38 and 40 respectively.
- Pan portion 36 is provided with a water supply inlet 42 adapted to be connected to a source of water.
- the water flow from inlet 42 is controlled by a float valve mechanism 44 to maintain a water level in sump 34 as indicated by dashed line 46.
- an overflow drain 48 is provided in end wall 40.
- a protective bafile 49 has been provided extending horizontally from end wall 40, over float valve mechanism 44, and then downward below water level 46. This 'bafile also minimizes mineral deposits at the seat of the valve by reducing evaporation therefrom.
- an elongated bristle supporting core 50 having a generally horizontal axis.
- Core 50 may be constructed by twisting two wire elements 52 to form a pair of coextensive coaxial helicoids of substantially equal diameter.
- semirigid elongated bristles 54 may be interposed between the wire elements.
- These bristles are best shown in FIGURE 4. They are preferably made of monofilament water impervious nylon fiber and are crimped at intervals to improve water pickup and to increase the evaporative surface area. The bristles extend radially outward from the core in a plane normal to the longitudinal axis thereof.
- core 50 is provided with a journal 56 disposed in a plastic bearing 58 carried in end wall 38 above water level 46.
- the other end of core 50 is provided with a coupling member 60 adapted to be connected to the drive member 62 of electric motor 64 which is mounted on the exterior side of wall 40.
- FIGURE 3 shows core 50 disconnected from drive member 62. Coupling of elements 60 and 62 is accomplished by sliding core 50 to the left (FIG. 3) so that the tongue of coupling member 60 is disposed within the groove of drive member 62. A cylindrical retainer 66 is then slid from the position shown to a position over both members 60 and 62 thereby holding core 5% in coaxial driving relation with drive member 62.
- Drive member 62 and bearing 5 are arranged so that the axis of core 50 is generally horizontal.
- the bristles 54 are of sufficient length to extend below water level 4-6 when in the downwardly extending position and into the vaporizing chamber when in the upwardly extending position.
- Electric motor 64 is selected to rotate core 50 be tween about .5 to about revolutions per minute.
- Motor 64 may be provided with a junction box 68 for suitable electrical connection to a source of electric power.
- An end cover 70 which has been removed in FIGURE 2 may be provided to cover junction box 68 and overflow drain 48 and improve general appearance.
- Inlet opening I8 is rectangular in shape and positioned to direct hot unsaturated air from the furnace directly over the bristles which extend upward into the vaporizing chamber.
- a generally horizontal baflie '72 extends from duct 14 over inlet opening 13 to a point directly above core 50 adjacent to uppermost ends of bristles 54 thereby deflecting a major portion of the air passing inlet 13 over bristles 54.
- An air humidifier apparatus comprising: a housing defining a water sump in the lower portion thereof; means for admitting a solution of water and minerals to said sump; and means separating substantially all of said minerals from said water and passing said resulting mineral free water into a stream of air including: an elongated bristle supporting core having a generally horizontal longitudinal axis; support means connected to said housing supporting said elongated core for rotation about said axis; surface means for evaporating water therefrom comprising a plurality of elongated bristles supported by and extending substantially radially outward from said core; said bristles being arranged longitudinally along and circumferentially about a :portion of said core; said bristles having a length greater than the diameter of said portion of said core and each of said bristles being supported solely at its radially inner portion whereby the radially outer portion is permitted to fiex for loosening and removing inflexible scale deposits formed by the evaporation of mineral containing water therefrom;
- said last means including a motor means connected to said core to rotate said core for slowly rotating said bristles alternately between said water sump and said stream of air.
- An air humidifier apparatus comprising: a housing defining a water sump in the lower portion thereof; an elongated bristle supporting core having a generally horizontal axis; support means connected to said housing for rotatably supporting said elongated core about said axis above the normal water level in said sump; surface means for evaporating water therefrom comprising a plurality of elongated bristles supported by and extending radially outward from said core; said bristles being spaced longitudinally along and circumerentially about a portion of said core; each of said bristles being supported solely at its radially inner portion whereby the radially outer portion is permitted to flex for loosening and removing inflexible scale deposits formed by the evaporation of mineral containing water therefrom; float valve means disposed within said water sump for maintaining a normal water level in said sump sufliciently high that said bristles extending downwardly from said core are deeply immersed in the water of said sump; means for passing a stream of air
