Description

Pipe insulation insulation manufacturing device using aerogels {Aerosol pipe with a heat insulation}

The present invention relates to a pipe insulation insulation manufacturing apparatus using an airgel, and specifically, the present invention can be formed in a short time by forming an airgel with excellent thermal insulation power, pipe insulation insulation manufacturing apparatus using an airgel beautiful appearance after installation It is about.

In general, large structures such as heat exchangers, various pipes, and appliances use thermal insulation materials in order to prevent the temperature of the internal fluid from being lowered or to prevent workers from being damaged by these structures at high temperatures.

However, the conventional thermal insulation material is insulated in a narrow space that was not considered in the design, energy loss due to formal thermal insulation, corrosion of internal thermal pipes (CUI), overdesign of the support such as pipe racks with abnormal insulation volume, the insulation itself Insulation effect and durability decrease due to moisture absorption, insulation and damage to the insulation during walking, damage to the human body according to the components of the insulation, transportation and storage problems, etc. As a heat insulating material to solve such problems, pearlite and glass fiber The family is mainly used.

The pearlite has the advantage of low material cost, but weak to moisture, high weight and high volume, breakage and breakage during impact, industrial wastes are generated.

On the other hand, the glass fiber has the advantage of having a high heat resistance, but there is a problem that the glass needle's harmfulness, human hazards are raised and the performance and durability are degraded by water absorption.

If moisture is absorbed into the insulation, the leaked heat is transferred to the support structure, so that the temperature at the bottom of the pipe is markedly different from the temperature at the top, thereby attenuating the insulation performance.

This caused a waste of thermal energy due to a decrease in thermal efficiency due to heat loss.

Therefore, as a way to solve the above problems, domestic application No. 10-2008-0012329 "Insulation insulation for air conditioning duct using aerogel and its construction method" has been proposed.

The properties of the airgel is 90-99.8% of the air, the density is usually 3-150 mg / cm3. The airgel feels like styrofoam, but it's not soft and won't restore when pressed once. If you press very hard, it breaks into pieces like glass. Although it has a cracking property, it is structurally very strong and can lift 2000 times its own weight. This is due to the microstructure in which spherical particles of 2-5 nm size combine to form branched clusters. These clusters form three-dimensional fractal-like meshes that form porous structures with pores smaller than 100 nm. The average size and density of pores can be controlled during the manufacturing process.

In addition, aerogels exhibit significant thermal insulation performance because they neutralize the three methods of heat transfer: convection, conduction and radiation. The reason for effectively blocking convection is that air cannot circulate through the pores. The reason for effectively blocking conduction of silica airgel is that silica is a poor thermal material. (Metal aerogels, on the other hand, can be better thermal conductors.) Carbon aerogels effectively block radiation because carbon absorbs infrared radiation, which causes heat transfer. The best adiabatic airgel is carbon-added silica airgel.

The airgel feels dry due to its hygroscopicity and acts as a powerful dehumidifier. Most of them are made of air, so they are translucent, and the color comes from the scattering of short wavelengths of visible light due to the nano-sized resin structure. This results in a bluish color on a dark background and white on a light background.

Aerogels are hydrophilic by themselves, but can be made hydrophobic through chemical treatment. Absorption of water causes structural changes, such as shrinkage or decomposition, which makes it hydrophobic and can prevent it. Hydrophobic treatment to the inside prevents the airgel from decomposing even if deep cracks occur. If hydrophobic treatment is applied, waterjet cutting can be performed.

As shown in FIG. 1, the thermal insulation material using the airgel is composed of an airgel plate 100 and a winding member 200, and the airgel plate 100 is formed of an airgel material.

At this time, the airgel plate 100 is added to the additive and the fiber structure, by applying a supercritical drying method to completely extract the liquid component from the gel state reinforced with the fiber structure to prevent the airgel particles from breaking or breaking Is formed.

The winding member 20 is formed in a thin plate shape to surround the airgel plate 10, but was formed of a material that reflects heat using aluminum thin plates or aluminum laminating.

Looking at the process installed in the air-conditioning duct using the thermal insulation material as described above,

First, the airgel plate 10 is cut out by adding an extra of about 10% to 20% of the circumferential length of the air conditioning duct 1.

Subsequently, when each airgel plate 10 is wrapped around the air conditioning duct 1, the airgel plate 10 is overlapped with each other by an extra length to completely surround the circumference.

Next, the fixing member 11 is used to fix the airgel plate 10 to the air conditioning duct 1.

At this time, the fixing member 11 may be used by various means such as adhesive, tape or wire.

Next, the winding member is wound around the airgel plate 10 wound around the air conditioning duct 1.

Next, the winding member 20 surrounding the airgel plate 10 was fixed by wrapping the circumference using the finishing fixing member 21.

However, the airgel plate 10 installed as described above, when the air duct (1) is wrapped, the airgel and the airgel overlap, the space is created, and the lifting effect occurs when the fixing member using a fixing member wire, etc. Was lowered.

In addition, the appearance was not good after the construction.

In addition, the construction time is long, there was a problem that a lot of unnecessary subsidiary materials are required.

As another example, Japanese Patent Application Laid-Open No. 2010-85059 discloses a heat insulating device and a heat insulating method for an air conditioner duct.

That is, it is a thermostat and a thermal insulation method of the air conditioning duct piped indoors,

The thermal insulation sheet is a surface paper adhered to the surface of the heat insulating material such as glass wool (glass wool).

When the insulation sheet is wound around the tube, one or more sheet joining bands are provided in the surface layer in a direction orthogonal to the longitudinal direction of the tube, and the sheet joining band has a male-type locking claw at one end. A male engaging portion is formed, and a male engaging claw and a female engaging piece to be engaged are formed at the other end.

The direct tube was wound around the heat insulating sheet or the elbow tube was wound around the elbow insulating sheet, and both of the insulating sheets were bonded to the sheet joining band, and the sheet fixing tape was adhered to the joints of the respective insulating sheets.

However, such a thermal insulation device has the advantages and disadvantages that the thermal insulation power is lower than when using the former airgel, but excellent in the construction method and beautiful appearance.
