Description

  The present invention relates to a heated and humidified air blower. More specifically, heating and humidification that has the function of converting activated water into saturated steam, then converting it into superheated steam, and then discharging it as warm air for heating and humidification can realize energy saving. The present invention relates to an air blower.

As a conventional heated air blower, for example, a warm air fan heater or a petroleum fan heater is widely used.
The hot air fan heater includes a heater that heats air, a fan that blows air heated by the heater, and a housing in which these are arranged, and after the air in the housing is heated by the heater, The interior of the room is heated by blowing heated air from the outside.
The oil fan heater includes a tank that stores oil, a burner that burns oil supplied from the tank, a fan that blows air heated by the burner, and a housing in which these are arranged. The room is heated by blowing air heated by a burner from the inside of the housing to the outside.
However, in the case of a conventional hot air fan heater, the air is heated by the heater and blown into the room with the air further dried, so the indoor air is dried and the heat capacity of the hot air is small, Heating efficiency is poor. Also, in the case of oil fan heaters, carbon dioxide is generated by burning oil, so indoor ventilation is necessary, and the environment is further burdened by carbon dioxide. From the viewpoint of global warming, it is as much as possible. A heater with low environmental impact is desired.
As a heater having a function of preventing indoor air from drying, there is one using superheated steam.
It is known that if saturated steam is heated, it becomes dry steam, and the steam temperature can be raised to a high temperature. Such high-temperature dry steam is generally called superheated steam and is known as a heating medium for a sauna bath (for example, Patent Document 1).
In addition, superheated steam has been used as a heating medium in food processing, thawing, roasting, drying, carbonization, drying, volume reduction of organic waste, various heat sources, metal surface treatment, etc. (For example, Patent Documents 2 to 4).
Superheated steam has high activity at high temperatures, easily rises to about 800 ° C, easy to control temperature, high ability to transfer substances and heat from dry air, incineration ability of substances and oil It has a function suitable for roasting food that does not like oxidation, such as its high removal function.
As a conventional superheated steam generator, a heated part formed by winding a metal tube in a coil shape is heated by induction heating, and saturated steam is passed through the heated part to generate superheated steam. (For example, Patent Documents 5 to 8).
On the other hand, tourmaline (group name is “tourmaline”) and drabite (tourmaline with high magnesium content, also known as “bitter tourmaline”) are natural minerals with semi-permanent electrodes of about 0.02 to 0.06 milliamps. There are various uses known.
For example, as a technique for generating active ionic water without providing a power supply outside, an active ionic water production apparatus that makes water clusters small with tourmaline ore has been proposed (Patent Document 9). In addition, pressure is applied to tourmaline ore, obsidian, beitou stone, barley stone, radium ore, etc. with heat to generate negative ions, far infrared rays, humidity, etc. Since it can mix, using for a sauna bath is proposed (patent document 10).
Various technologies as described above have been proposed, but active ion water that has been negatively ionized using drabite ceramic (hereinafter sometimes simply referred to as drabite) is used as superheated steam and used as a heating and humidifier. Proposals to make have never been made.

Hereinafter, it demonstrates in detail using FIG. 1 which showed one embodiment of this invention.
In the present invention, the drabite ceramic 1 is used in a water tank 2.
Drabite has a high magnesium content among various tourmalines. Drabite is a polyhedral polar crystal with an electric power of about 2.5 times that of other tourmalines, a natural mineral with a semi-permanent electrode of about 0.06 milliamps, and is prominent from the Tianshan Mountains in China. is there.
The general main components of the drabite ceramic are SiO ₂ : 32.7 mass%, B ₂ O ₃ : 9.34 mass%, Al ₂ O ₃ : 23.34 mass%, Fe ₂ O ₃ : 3.81 mass% , MgO: 22.64 wt%, CaO: 2.30 mass%, Na ₂ O: 0.35 wt%, Li ₂ O: 0.20 wt%, P ₂ O _5: 0.05 wt%, F: It is introduced that it is 0.06 mass%, and others are 5.12 mass% (Unexamined-Japanese-Patent No. 2005-319441).
In the present invention, the drabite ceramic is used by adjusting the particle size to preferably 3 to 10 mm, usually about 7 mm. Smaller particles are preferable because the area in contact with water in the water tank increases, but it is controlled in the above range from the viewpoint of water flow resistance, blockage over time, and economic efficiency.
In addition, since drabite ceramic is a natural mineral, it may contain various water-soluble or oil-soluble components, so it must be washed with water and / or organic solvents at the stage of being crushed before use. It is preferable.
The effect of the drabite ceramic in the present invention is presumed to be due to the following mechanism.
Adsorption effect due to weak current generated from drabite ceramics can be given, and water can be activated by the electrolysis of water and the generation of negative ions by combining OH ^- ions and water molecules. .
The drabite ceramic used in the present invention is preferably used as a mixture with metal particles or metal colloids such as silver, titanium, and platinum.
When mixing, the drabite ceramic is used by adjusting the maximum particle size to 0.5 to 10 μm, preferably 0.5 to 3 μm, usually about 2 μm, and then sized to about 7 mm.
The size of the metal particles or metal colloid is preferably approximately the same as the size of the drabite ceramic particles. The metal particles or metal colloids are usually prepared by reducing each metal halide or the like using a reducing agent such as formaldehyde. It is also possible to prepare an aqueous solution of a salt of each metal and apply this to an oxidizing flame of a gas burner. A coating agent is prepared by mixing each metal particle or metal colloid thus prepared with a drabite ceramic particle and mixing with a binder described later.
Silver and titanium can also be mixed with the drabite ceramic particles in the form of an aqueous solution of nitrate, sulfate, hydrochloride or the like. Platinum is mixed as an aqueous solution such as chloroplatinic acid. Prepare an aqueous solution of these salts (preferably using purified water), mix and dry the drabite ceramic particles, and then reduce it with a reducing agent such as a reducing flame or formaldehyde. In the present invention, a mixture of metal particles or metal colloids deposited on the surface of the drabite ceramic particles is also regarded as a mixture. Two or more kinds of silver, titanium, and platinum may be mixed and used. Content of a metal is 0.2-10 mass% in the total amount of a mixture with a drabite ceramic, Preferably it is 1-8 mass%.

In FIG. 1, a drabite ceramic 1 has a role of activating water that becomes water vapor to change it to negative ion water.
Normally, water is intermittently supplied from the supply nozzle 3 while controlling the water level inside the water tank 2 to a certain depth. In order to control the water level to a certain depth, an electric water level control unit may be used, but a simple ball tap 4 is preferably used. The ball tap 4 is connected to the open / close valve of the supply nozzle 3 via a connecting rod.
The set water level can be adjusted by changing the mounting position in the vertical direction of the supply nozzle 3 connected to the ball tap 4 as shown by a dotted line in FIG.
The supplied water is preferably tap water for drinking. Water that does not contain residual chlorine, such as industrial water, can be used, but if it is used for a long period of time, it will be contaminated by the slime adhering to the lower part of the drabite ceramic, water tank, connecting pipe and electric heater described later. It is not preferable because it takes time to replace the drabite ceramic with a new one in a short period of time.
The material of the aquarium 2 is not particularly limited, such as metal or plastic, but it can be made compact and durable, especially stainless steel, corrosion-resistant aluminum, aluminum alloy, galvanized steel, etc. These metals are preferably used. It is preferable that a lid is attached to the water tank 2 in order to prevent entry of dust and the like from the outside.

The size of the aquarium 2 is not particularly limited, but the water level of the aquarium 2 is always kept constant by a ball tap regardless of the size of the room in which it lives, and the size of the stable space that accommodates livestock. A size that can accommodate the ball tap is sufficient.
The drabite ceramic 1 is used in a state where it is placed in a horizontal position at the bottom of the water tank 2 and is completely immersed in water. In the case where the drabite ceramic 1 is allowed to stand on the entire bottom surface of the water tank 2, the ball tap (float part) 4 is adjusted so as to be about 70 to 90% of the height of the water surface from the viewpoint of the vertical operating range of the ball tap (float part) 4.
The drabite ceramic does not necessarily have to be left standing on the entire bottom surface of the water tank. As shown in FIG. 1, a partition plate (lower or porous) may be provided on the bottom surface of the water tank and left on one side. Good. In short, it suffices if all the water supplied from the supply nozzle 3 is devised so that it always comes into contact with the drabite ceramic.
In order to fully activate the water to be used, drabite ceramics having a volume of about 1/40 to 1/30 times (volume ratio), preferably 1/20 to 1/15 times (same) of the amount of evaporated water per hour are used. It is advantageous to use. In the case where the drabite ceramic is allowed to stand on the entire bottom surface of the water tank 2, a partition plate may be provided for forming a zigzag passage so that the water can contact as long as possible. However, when arranging the partition plates, it is necessary to devise so as not to hinder the vertical operation of the ball tap (float portion).

Next, the connecting pipe 5 will be described. As shown in FIG. 1, the connecting pipe 5 connects the bottom of the water tank and the bottom of the heating part described later, to the heating part of water activated by drabite ceramic in the water tank. It becomes a passage. Regardless of the size of the water tank 2, the water level becomes constant due to the atmospheric pressure applied to the water tank 2 and the steaming section 14, and therefore it is sufficient that the inner diameter of the connecting pipe 5 is about 6 to 8 mm. In order to allow water to contact the stationary drabite ceramic for as long as possible, it is preferable that the connecting pipe 5 is provided at a location separated from the water supply nozzle 3 in the horizontal positional relationship.
The connecting pipe 5 may be made of the same metal material as the water tank 2 or may be made of a silicon tube or the like. It is preferable that the connecting pipe 5 has a removable structure in consideration of regular cleaning.

Next, the heating unit will be described.
The heating part is composed of an electric heater 6 and a cylindrical body 7. Unless there are special circumstances, the heating part is provided substantially vertically as shown in FIG.
A ceramic layer 8 having a function of emitting far infrared rays is provided on the inner wall surface of the cylindrical body 7. The ceramic layer 8 can usually be formed by applying a far-infrared paint.
Examples of the ceramic include sintered ceramics having far-infrared radiation such as SiO ₂ , Al ₂ O ₃ , TiO ₂ , ZrO ₂ , Fe ₂ O ₃ , CuO, MgO, NiO, Li ₂ O, CoO, and the like. The particle size is 100 μm or less, more preferably 15 μm or less. By making the average particle size of the ceramics 100 μm or less, it is possible to prevent the ceramic layer from falling off easily. These ceramics are used alone or in combination of two or more. Of these, SiO ₂ , Al ₂ O ₃ and TiO ₂ are remarkably excellent in far-infrared radiation effect.
In order to form the ceramic layer, a method such as thermal spraying, CVD, or sputtering may be used. However, a slurry-like far-infrared paint or silicic acid in which the particles of the fired ceramic as described above are dispersed in a liquid silane compound or the like. A slurry-like far-infrared paint in which the above sintered ceramic particles are dispersed in an aqueous solution of sodium or potassium silicate is preferably used.
By heating the coating layer of the applied slurry-like far-infrared paint at a predetermined temperature, the entire coating layer can be cured to form a ceramic layer, improving the adhesion of the cylindrical body to the substrate, The strength of the ceramic layer itself is also improved, and the detachment of the ceramic layer can be prevented.
As a specific example of the far-infrared paint, for example, silica-alumina-based liquid ceramic paint (for example, liquid ceramic manufactured by Ceramission Co., Shellac α-1500, etc.) is preferably used. A ceramic layer formed from silica-alumina-based liquid ceramics has extremely high heat resistance, and can be used, for example, in equipment that contacts molten iron at about 1000 ° C.
The thickness of the ceramic layer 8 should just be about 50-200 micrometers normally.
The cylindrical body 7 is provided without contacting with the electric heater 6, and an elongated space 12 having an annular cross section is formed in the vertical direction. The transverse space 12 has an annular space 12 which is saturated steam and superheated by changing it. It becomes a passage for water vapor. However, a thin connecting portion that does not hinder the passage of saturated steam or superheated steam may be provided in some places as a support.
The bottom of the cylindrical body 7 is connected to the end of the connecting pipe 5 in a watertight manner, and flows into the bottom of the electric heater 6 provided inside the cylindrical body 7 via the connecting pipe 5. The activated water comes into contact and saturated water vapor is generated in the water vaporization section 14. The saturated steam generated in the steaming section 14 rises, and the cross section of the electric heater 6 and the tubular body 7 where no activated water is present is directly heated in the annular space 12 to be changed to superheated steam. At the same time, part of the heat generated from the electric heater 6 is converted into far infrared rays in the ceramic layer 8, and the far infrared rays are emitted toward the center, that is, toward the electric heater 6. It contributes to heating to change to superheated steam.
The length (height) of the electric heater 6 and the cylindrical body 7 is preferably set slightly longer (higher) in the latter so that the former does not protrude from the latter. This is for the purpose of preventing the generation of heated steam due to the ventilation of the fan into the cylindrical body 7, and it is preferable that the cylindrical body 7 is made higher by about 2 to 3 cm than the tip of the heater 6.
The material of the cylindrical body 7 is not particularly limited as long as it is heat resistant, but a material having good adhesion to the ceramic layer described later is preferable. Specifically, a stainless steel plate, an aluminum plate, a steel plate and the like whose surfaces are roughened can be used.
The cylindrical body 7 is preferably cylindrical from the viewpoints of design, ease of processing, strength, and the like.
The output of the electric heater 6 is selected according to the purpose of use. For example, when it is desired to obtain an output instantaneously, it is preferable to make a selection according to the application, such as increasing the output of the heater 6 or increasing the number of heaters. For example, in the case of the heating and humidified air blower for about 6 mats, it is about 3 kW, and in the case of the heating and humidified air blower for the stable, it is about 3 to 10 kW. The heater 6 is controlled by a temperature control unit and automatically enters and exits according to a set temperature, and the temperature setting can be arbitrarily adjusted.
The amount of water vapor generated depends on the output of the electric heater 6 and the water level setting position, that is, the depth of water flowing into the bottom.
The electric heater 6 may be a quartz tube heater or a sheathed heater. The electric heater 6 is preferably composed of a semiconductor heat exchange element. The ceramic layer as described above may also be formed on the outer peripheral portion of the electric heater 6, and far infrared rays are also generated from this ceramic layer, which contributes to heating and changing the saturated steam to superheated steam.
A heat insulating cover 10 is preferably provided on the outside of the cylindrical body 7 as necessary from the viewpoint of improving safety and thermal efficiency.
As shown in FIG. 1, a space 13 having an annular cross section is formed in the vertical direction between the inside of the heat insulating cover 10 and the outside of the cylindrical body 7, and the space 13 having an annular cross section is the lower part. It becomes a passage for indoor air that flows in and flows out from the top, and collects almost all of the heat generated from the electric heater 6 together with the heat insulation effect in one place, that is, the upper opening (the three arrows on the upper right in FIG. 1). It has the role of exhausting indoors as warmed and humidified air. Also between the inner side of the heat insulating cover 10 and the cylindrical body 7, a thin connecting portion that does not hinder the passage of room air may be provided as a support in some places.

Next, the air blowing means 9 attached to the top of the cylindrical body will be described.
The blower means 9 comprises a fan and a blower passage, and the lower surface of the blower passage is provided with confidentiality to the outside of the electric heater 6 and the uppermost opening of the cylindrical body 7 as shown in FIG. Connected. In the case of the heating and humidified air blower for about 6 mats, the fan has a blowing capacity of about 2.2 to 2.5 m ³ / min. In the case of the heating and humidified air blower for the stable, 2.2 to 2.2 It is about 9.0m ³ / min.
The superheated steam heated to about 500 to 800 ° C. by the indoor air sent by the fan is sucked from the upper part of the passage whose annular cross section is annular, and is diluted and heated and humidified to about 60 to 160 ° C. It is discharged indoors as wind. For safety, a temperature sensor is provided at the hot air outlet, and when the fan stops due to a failure or the like, the electric heater 6 is turned off so that the hot superheated steam is not discharged as it is. It is preferable to keep it.

  In FIG. 1, reference numeral 11 denotes an electrode portion for supplying electric power to the electric heater. This electrode portion 11 can be connected to a one-phase, two-wire, 200-volt power source or a three-phase, three-wire, 200-volt power source. Thus, an electrical connection terminal is provided. Also, the current value of 1 / √3 times is suppressed in the three-phase three-wire 200 volts than in the one-phase two-wire 200 volts, so the power supply for installing the heating and humidified air blower is three-phase three-wire 200 volts. Good.

Examples of the present invention will be described in detail below, but the present invention is not limited to these examples.
[Preparation Example 1]
<Preparation of drabite ceramic particles>
The drabite ore produced in the Tianshan Mountains of China was pulverized by using a pulverizer manufactured by Guilin China Mining Equipment Co., Ltd. and a lightning wind selector, and passed through a 2000-4000 mesh filter to prepare 10 kg of drabite particles. The particle size distribution of the drabite particles was 2 to 5 μm.
A mixture obtained by mixing platinum particles, titanium, and silver colloidal particles with the drabite particles so as to be 4% by mass (platinum, titanium, silver, etc.) in the mixture was increased to a particle size of about 7 mm.

[Comparative Example 1]
The drabite ceramic was removed from the heated and humidified air blower used in Example 1 above, and the same conditions as in Example 1 were followed. The room temperature at the start of the measurement was 26 ° C. and the relative humidity was 41%. The results are shown in Table 2.
The number of negative ions was measured in the same manner as in Example 1 except that the drabite ceramic was removed.

In addition, as shown in Table 3, in Reference Example 1 in which water was not used, there was a heating (heating) effect, but the relative humidity decreased over time, which was inappropriate as a living environment for humans and animals. It can be seen that it is. Negative ions are generated approximately 2.5 times when using Drabite Ceramic, and the number of negative ions existing in the vicinity of the waterfall is 4700 / cm ³ in nature. It can be seen that

[Reference Example 2]
Test for confirming heating effect on superheated steam substance (1) Using drabite and water In order to align the conditions at the start of the test, the factory was cooled and kept at 24 ° C. In the same tent as described above, the following pieces of wood and copper plates were used.
