Description

[Detailed description of the invention] This invention relates to a steam spray humidifier, and more specifically, by providing a large opening in the container body constituting the steam release part and blocking this opening with a water-repellent moisture permeable member. The present invention relates to a steam spray humidifier equipped with a steam discharge section that only allows steam to be blown out from the opening.

A simple conventional steam spray humidifier for air conditioning is as shown in Figs. There is a single-tube spray nozzle in which steam flows in from the end and is ejected from the nozzle using the steam pressure inside the pipe, but the diffusion angle of the steam coming out of the small hole 2 or nozzle 3 is narrow, and the steam is When blowing out, it may make a whistling sound, or the condensed water that has condensed during the piping or the pipe body 1 may wet the structure where the blowout is installed from the small hole 2 or nozzle 3 together with the steam. Since the opening area of the nozzle 3 is small, the heating and absorption distance required for the vapor to dissolve into the air is long, resulting in the disadvantage that dew condenses on the side panels of the duct and on obstacles (not shown).

Furthermore, as shown in Fig. 5, a plurality of small holes 2 are made in the tube body 1, one end of which is closed. A double pipe spray nozzle has been proposed that is inserted into an outer tube 5 with an opening 4 facing upward, but this spray nozzle not only has the drawbacks of the conventional example described above, but also has the problem that steam is blown from the opening 4. When putting it out,
As shown in FIG. 5, dew condensation is likely to occur at a point P where the discharged steam 6 overlaps, leading to a decrease in efficiency.In addition to the drawbacks that the steam is discharged unevenly and the humidification becomes uneven, the outer tube 5 is cooled. If a large amount of condensed water accumulates inside the outer tube, open the small hole 3.
The disadvantage is that the steam spills outward from the opening 4 and wets the structure where it is installed, as described above.

The purpose of this invention is to eliminate the above-mentioned drawbacks, and its feature is that a large opening is provided in the tube or container that constitutes the steam release section, and this opening is made of water-repellent and moisture-permeable material. To provide a steam spray humidifier which is equipped with a steam discharge part which is closed with a member and which allows only steam to be blown out from the opening, and which does not cause condensed water to be blown out, dew condensation, or resonance to occur. Hereinafter, this invention will be described in detail with reference to an embodiment shown in FIGS. 6a-c and 7.

In the steam spray humidifier of this invention, a large opening 13 is provided in a tube or container body 12 with one end closed, constituting a steam emitting part 11 for emitting steam, and a uniform porosity having a large porosity is formed around the edge of the opening 13. Ceramic porous material with a tertiary network skeleton structure, synthetic resin materials such as tetrafluoroethylene, specific polyolefins, polyethylene chloride, vinylidene fluoride, nylon, polyamide, water-soluble substances, specific carbonates, surfactants, crystals Water repellency and moisture permeability of resin membrane porous materials with high porosity are obtained by mixing specific mixtures of substances, etc. into a film, and then removing it by extraction or dissolution with water, organic acids, non-solvents, etc. A water-repellent moisture-permeable member 14 made of a plate or a membrane-like member is adhered to close the opening 13 with the moisture-permeable member 14, and the other end of the pipe or vessel body 12 is connected to the electromagnetic valve 15 and the flow rate determining joint 16. A trap valve 19 and a drain are connected to the steam pipe 17 connected to a steam generation source (not shown) through the pipe, and between the drain pipe 18 attached to the other end of the pipe or vessel body 12 and the flow rate determining joint 16. It has a configuration in which a collecting pipe 20 is connected.

In the figure, reference numeral 21 denotes a mounting plate for mounting the steam discharge section 11 to a package air conditioner, duct, air handling unit, etc. as an air conditioner that requires humidification.

The steam spray humidifier of this invention is constructed as described above, and the release of steam in this humidifier will be described below. Steam sent from a steam generation source (not shown) through steam piping 17 is throttled to a predetermined amount of steam by a flow rate determining joint 16, as shown by an arrow, and then enters the electromagnetic valve 15. At this time, water droplets condensed in the middle of the piping pass through the trap valve 19 and exit from the drain collecting pipe 20 to the drain pipe 18.

The steam that has passed through the electromagnetic valve 15 enters the pipe or vessel 12 that constitutes the steam release section 11 as shown by the arrow, and is water repellent and moisture permeable through the opening 13 at a vapor pressure of 0.5 Kg/cm ² G or less. As shown in FIG. 7, only steam is discharged almost uniformly and slowly from the entire surface of the opening through the fine pores of the plate or moisture permeable member 14, and water droplets that have condensed inside the pipe or vessel body 12 are blocked from being discharged. , flows through the bottom of the pipe or vessel body 12, collects at the trap valve 19, and is discharged outward from the drain pipe 18, as shown by the dashed arrow.

As described above, this invention provides a large opening in the pipe or vessel constituting the steam release section, and a moisture permeable member 14 having water repellency is provided around the edge of this opening 13.
The opening 13 is closed with a moisture permeable member 14, and the opening allows only the blowing out of steam, so even if the opening for releasing steam is enlarged, the plate or moisture permeable member remains water repellent and moisture permeable. An even vapor pressure is built up between the two (steam will not pass through unless pressure is applied), and during this passage, the passage cross-sectional area is extremely large compared to the small hole or nozzle, so the speed of steam release is extremely low, and the sound generated is emitted. The vapor does not cause any noise disturbance, the vapor diffuses very easily after being blown out, dissolves into the air immediately after being blown out, and the structure is extremely simple and inexpensive.
