〔産業上の利用分野〕
本発明は、空気の顕熱を利用して空気に湿分を
付与する加湿効率の高い加湿器に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a humidifier with high humidification efficiency that adds moisture to air by utilizing the sensible heat of the air.
空気の湿分を付与する従来の加湿器には、大き
く分けて、
熱源により水を加熱して蒸発させる方式、
通過空気中に加圧水をスプレーする方式、
高圧空気または超音波で微小水滴を形成しこ
れをスプレーまたは噴霧する方式、そして、
水を湿潤させた気体透過性の膜体に空気を通
過させる方式、などが知られている。
Conventional humidifiers that add moisture to the air can be roughly divided into two methods: one that uses a heat source to heat water and evaporates it, one that sprays pressurized water into the passing air, and one that uses high-pressure air or ultrasonic waves to form microscopic water droplets. Methods of spraying or atomizing this, and methods of passing air through a gas-permeable membrane moistened with water are known.
前記の各方式にはそれぞれ得失があるが、の
方式では熱源が必要であり、装置が複雑化すると
いう問題がある。
Each of the above methods has its advantages and disadvantages, but the method requires a heat source and has the problem of complicating the apparatus.
の水スプレー方式は回転円盤などを用いて水
滴を作るのが一般であるが、液滴が大きくなり、
加湿効率（水の蒸発量／散水量）並びに飽和効率
（実際加湿量／理論加湿量）が共に小さくなり、
また気流中にスプレーするために加湿スペースが
大きくなるという問題がある。 The water spray method generally uses a rotating disk to create water droplets, but the droplets become larger and
Both the humidification efficiency (water evaporation amount/water sprinkling amount) and saturation efficiency (actual humidification amount/theoretical humidification amount) decrease,
There is also the problem that the humidifying space becomes large because the spray is sprayed into the airflow.
の微小水滴を形成する方式では動力が大きく
超音波を利用する場合には超音波振動子が故障し
易いという問題があり、また水滴中の蒸発残渣分
がほこりとなるという問題がある。 In the method of forming minute water droplets, there is a problem that the ultrasonic transducer is likely to break down when the power is large and ultrasonic waves are used, and there is also a problem that the evaporation residue in the water droplets becomes dust.
の膜状加湿器において、多孔性の不織布に水
をかけてその中を空気を通す方式では膜を厚くす
ると圧損が大きくなり膜を薄くすると飽和効率が
悪くなるという問題がある。また膜を水タンク内
を潜らせて湿潤させる場合には動力か必要となる
ほか、膜に付着した雑菌がタンク内で繁殖する危
険がある。 In membrane humidifiers, water is poured onto a porous nonwoven fabric and air is passed through it, but there is a problem in that thicker membranes result in greater pressure loss, while thinner membranes result in poorer saturation efficiency. Furthermore, when the membrane is submerged in a water tank to moisten it, power is required, and there is a risk that bacteria attached to the membrane will breed inside the tank.
そして、〜の方式で共通して言えることは
風速が大きくなると水滴が気流に同伴して飛散す
るという問題と、水中の存在する析出性物質がど
こかに析出してスケールとなるかこれが空気中に
拡散するという問題がある。そして、〜の方
式では加湿効率または飽和効率のいずれか一方ま
たは両方が低いという基本的な問題がある。 What is common to these methods is that when the wind speed increases, water droplets are scattered along with the airflow, and whether precipitable substances existing in the water will precipitate somewhere and become scale. The problem is that it spreads. In addition, the basic problem with the methods is that either one or both of humidification efficiency and saturation efficiency is low.

As a humidifier that solves the above-mentioned problems, the present invention uses a rectangular inorganic porous corrugated plate processed from inorganic fiber paper. The transversely corrugated rectangular plates and the longitudinally corrugated rectangular plates, which have approximately the same external size, are stacked alternately with the plates vertically so that the waves are perpendicular to each other. A porous block body is formed whose width and height are determined by the length of the plate, and whose lateral length is determined by the number of plates, and this porous block body is fixed with a frame.

定する。 With the above-mentioned purpose in mind, the present inventors have conducted various tests and studies to develop a non-powered humidifier that has particularly high humidification efficiency and saturation efficiency, and is free from scale and germ problems. As a result, if the inorganic porous plate is made to contain water and allow the water to flow out temporarily, and the inorganic porous plate is assembled into a specific shape, the above purpose is almost achieved and it is very economical. It was found that targeted and efficient humidification can be performed. In particular, when the humidifier of the present invention is incorporated into an air conditioner, such as an outdoor air conditioner, it can humidify, collect bacteria and sea salt particles, and purify the air at the same time.
Can withstand high temperatures. It is desirable that the inorganic porous plate used be porous so that it can sufficiently absorb water and the absorbed water can be sequentially washed away. From these points of view, it is effective that the inorganic porous plate constituting the porous block has a corrugated shape. More specifically, this inorganic porous plate is formed into transversely corrugated strips having waves in the width direction and longitudinally corrugated strips having waves in the longitudinal direction, and the transversely corrugated strips and the transversely corrugated strips have approximately the same external size. By stacking longitudinally corrugated strips alternately so that the waves are perpendicular to each other, the thickness can be adjusted to the width, height, length, and transverse direction of the board. A porous block body having a length determined by the number of blocks is formed, and this porous block body is fixed with a frame.

When manufacturing an inorganic porous corrugated sheet with the same shape as the single-stage product above, use an inorganic adhesive based on colloidal silica or sodium silicate, and when manufacturing a corrugated sheet consisting only of corrugated parts, use a It is desirable to use an organic adhesive since the flat paper portion is removed during the process. Regarding the shape of paper and single-stage products, limited to the humidifier according to the present invention, the thickness of the paper is 0.1 to 1.0 from the viewpoint of humidification efficiency and pressure loss.

う。 Next, after cutting the single-tiered product into an appropriate size, it is immersed in an inorganic curing agent, such as colloidal silica with a solid content of 10 to 40 wt.%, to impregnate the single-tiered product with colloidal silica. An inorganic porous corrugated plate having the same shape as the single-stage product is produced by firing (300 to 500°C) to remove components. When constructing a porous block body, this is done by combining this single-stage product with an inorganic porous corrugated plate having the same shape, or by combining only the corrugated portions, or by a combination of the two.

きる。 The hardening process is related to the size of the waves, the thickness of the paper, and the size of the porous block, but in some cases, the process is performed two or more times in order to impart the necessary strength. Further, the addition of porous powder such as fine silica powder or diatomaceous earth to the hardening agent is effective in controlling the pore structure of the wall of the corrugated plate, that is, the water content, water flow, water evaporation, etc. In addition, corrugated plates processed and processed from paper using alumina-silica fibers, silica fibers, alumina fibers, and natural inorganic fibers as paper materials can be made into sintered type inorganic porous corrugated plates by processing at 800 to 1300℃. can be produced.

An example is shown below. That is, in this example, in order to give sufficient strength to the thin transverse wave strip plate 1 and the longitudinal wave strip plate 2, a flat strip plate 3 is interposed between the thin transverse wave strip plate 1 and the longitudinal wave strip plate 2. By joining the line-contact parts of the transverse waves and the longitudinal waves of the longitudinal wave strip plate 2, a sandwich-like plywood with widthwise waves on one side and longitudinal waves on the other side is created. A porous block body 5 is formed by stacking the plywood sheets 4 vertically in the same direction. That is, when the plywood boards 4 are stacked in the same direction, the transverse wave strip plates 1 of one plywood board 4 alternately overlap the transverse wave strip plates 1 of the other plywood board 4.

らに膜流が形成さえることになる。 5 and 6 show an example of a humidifier according to the present invention using a porous block body constructed as described above. In this example, a total of nine units of porous block bodies 5 are stacked vertically in three stages and three rows horizontally. A water supply header 10 is installed on the uppermost surface of this laminated porous block body, and water is dropped from this water supply header 10 onto the upper surface of the laminated porous block body. On the other hand, the air to be treated is passed in the thickness direction of the porous block body. Water supply header 1
In order to supply water from the water supply header 10, as shown in FIG.
It is best to install the . In other words, the longitudinal wave strip plate 2 forms a zigzag passage in the air passage direction, but
Since only a hollow tube is formed in the vertical direction, if water is allowed to fall onto the longitudinally corrugated strip plate 2, it is possible that the water may fall without touching the inorganic porous plate. be. When water is continued to be supplied after the entire porous block body 5 has absorbed water, if water is allowed to fall onto each of the transverse wave short thin plates 1 one by one, the phenomenon of transverse waves is as shown in Fig. 8. A film-like water puddle 12 is formed in the upper part of the overhang, and when this water puddle 12 reaches a certain size, it comes into contact with the plate surface in the lower part and flows as a film flow, and the transverse wave strip plate 1 as a whole Further, a membrane flow is formed while all of the inorganic porous plates consisting of the longitudinally waved strip plates 2 remain impregnated.

てこれを系外に排出するものである。 One of the features of the humidifier of the present invention is that by temporarily supplying water to such a porous block body, that is, by simultaneously supplying water and draining water, the humidifier exists in water or in the air. This is to prevent precipitable substances from accumulating on the porous block body.
According to experiments conducted by the present inventors, when water is continuously supplied at a rate of 1.1 to 1.3 times the amount of water that evaporates through the porous block, the humidification efficiency reaches 70 to 90%, and scale formation is semi-permanent. I found out that it doesn't happen. Moreover, the proliferation of various bacteria does not occur at all.
This is because the porous block body 5 is inorganic;
This is thought to be because even if germs from the air land on the porous block, they will be washed away, or, in the case of tap water, a sterilization effect will occur due to the supply of chlorine ions from the continuous supply of fresh water. . Therefore, in the humidifier of the present invention, excess water is received by the drainage pan 13 below the porous block body 5 and is discharged out of the system.

As described above, according to the present invention, in a humidifier that humidifies air in an evaporative manner using the sensible heat of the air, a ceramic corrugate plate (processed from inorganic fiber paper and A porous block body consisting of a transverse wave strip plate and a longitudinal wave strip plate sintered at high temperature is made so that the falling direction of water and the passing direction of air are perpendicular to each other, and the inorganic porous plate itself retains water and has a film on its surface. Since the humidification is performed by constantly forming a temporary flow,
The air passing through the porous block body while being stirred can perform good heat exchange and phase change with the water in the porous block body, so that high humidification efficiency can be obtained with a minimum amount of liquid passing through. Also, according to experiments, a saturation efficiency of 60% was achieved using a porous block body with a thickness of 5 cm and blowing air at 3 m/sec. Further, the ventilation resistance in this case was very small at about 5 mmAq.
No humidifier that utilizes the sensible heat of air has ever been able to achieve such high saturation efficiency with low ventilation resistance. Furthermore, even when the air blow rate was increased to 10 m/sec, no mist was scattered on the downstream side.

The humidifier of the present invention is also beneficial in preventing electrical disturbances in modern office automation equipment. It has become known that the precipitation of salts in water causes them to scatter and cause corrosion and electrical damage, but the humidifier of the present invention does not suffer from such problems. Particularly in buildings near the coast, when sea salt particles are deposited inside the building due to flying sea salt particles, these salts are hygroscopic and promote electrical damage and corrosion, but air conditioners equipped with the humidifier of the present invention Not only will there be no precipitation of salts in the water used for humidification, but it will also serve to collect and discharge sea salt particles that fly into the atmosphere.
