Description

Heat exchanger with electrostatic spray dust collection unit {HEAT EXCHANGER WITH ELECTROSTATIC SPRAYING DUST COLLECTING UNIT}

The present invention relates to a total heat exchanger equipped with an electrostatic spray dust collection unit.

As the amount of time spent indoors, such as in residential facilities, public buildings, underground facilities, and offices, increases, interest in indoor air quality is increasing, considering the impact of indoor air on the human body.

The main factors that pollute indoor air quality are known to be particulate matter such as fine dust, asbestos, and dirt, and gaseous substances such as carbon dioxide, formaldehyde, and volatile organic compounds.

In order to remove the above-mentioned indoor pollutants, conventionally, a method of exchanging indoor air with external air through mechanical ventilation using a natural ventilation or air conditioning system is mainly used. Mechanical ventilation using an air conditioning system mainly uses a total heat exchanger that supplies outside air and exhausts indoor air while maintaining the indoor air temperature.

However, if a HEPA filter is used to increase the dust collection efficiency of the total heat exchanger, there is a problem in that the filter replacement cycle is shortened due to high pressure loss. Additionally, there is a problem that airborne bacteria contained in the outside air that is exhausted indoors are introduced into the room.

In addition, an inlet 132 is provided on one side of the housing 131 in communication with the external air outlet 112 of the main body 110, and an outlet 133 through which external air is discharged is provided on the other side of the housing 131. do.

The needle portion 134 includes a conductive plate 135 coupled to the inner upper side of the housing 131, and at least one needle coupled to the conductive plate 135 and disposed opposite to the ground portion 137 to spray reaction water. Includes (136).

One needle 136 may be provided at the center of the conductive plate 135, or a plurality of needles 136 may be provided on the conductive plate 135 to be spaced apart from each other.

The average particle diameter of the water droplets of the reaction water sprayed from the needle 136 may be 10 nm to 200 μm. This is to ensure that the reaction water sprayed from the needle 136 by electrostatic spraying has a particle size of 20㎛ or less and is converted into fine droplets.

The ground portion 137 is provided on the inner lower side of the housing 131 to face the needle portion 134 and to be spaced apart at a predetermined distance. The ground portion 137 includes a mesh-type ground plate provided at the lower portion of the needle portion 134.

The ground plate 137 is formed in a mesh type, so that the reaction water electrostatically sprayed from the needle 136 passes through the mesh type ground plate 137 and falls downward.

And so that the reaction water sprayed from the needle 136 generates hydrogen peroxide through electrostatic spraying, the power supply unit 138 applies a positive (+) voltage to the needle 136 through which the reaction water is sprayed, and is spaced a predetermined distance away from the needle 136. A high negative (-) voltage is applied to the ground plate 137.

In this embodiment, the amount of hydrogen peroxide produced in the reaction water per supply amount (ml/min) of reaction water sprayed from the needle 136 is set to be 0.001 ml/min to 0.05 ml/min.

For this purpose, the spray pressure of the reaction water sprayed from the needle 136 is 10 bar over 0 bar. In addition, the separation distance between the end of the needle 136 and the ground plate 137 may be 10 mm or more to prevent a short circuit from occurring between the end of the needle 136 and the ground plate 137 while the reaction water is electrostatically sprayed. And, the applied voltage between the needle 136 and the ground plate 137 may be ±5kV.

And when a high voltage is applied between the plurality of needles 136 and the ground plate 137, the water droplets sprayed from the plurality of needles 136 by electrostatic spraying are converted into fine droplets and ionized hydrogen ions (H ⁺ ) and hydroxide ions ( OH ^- ) can react again to produce hydrogen peroxide.

As the hydrogen peroxide and the reaction water of the micro droplets containing hydrogen peroxide fall, they remove foreign substances contained in the external air introduced into the interior of the housing 131 and sterilize floating bacteria contained in the external air. And the falling reaction water falls downward through the ground plate 137, is discharged to the outside of the housing 131, and is then stored in the storage tank 150, which will be described later.

In order to collect the reaction water sprayed and dropped from the needle 136, the lower part of the housing 131 located below the ground plate 137 may be formed in a cone shape inclined upward. Since the lower part of the housing 131 has a cone shape, the reaction water electrostatically sprayed from the needle 136 flows downward under its own weight.

Meanwhile, the principle of generating hydrogen peroxide by electrostatic spraying is explained as follows.

In this embodiment, the reaction water may include distilled water, bottled water, mineral water, deep sea water, ionized water, etc.

The reaction water may contain 1 to 200 mg/L of mineral components. The above mineral component may be at least one of iron, magnesium, potassium, potassium, sodium, silicon, and phosphorus. Additionally, the pH of the reaction water may be 5 to 10, and preferably the pH of the reaction water may be 6.7 to 7.3.

In addition, the reaction water has an evaporation residue of 30 to 200 mg/L, free carbon dioxide of 3 to 30 mg/L, a dilution batch number (Threshold Odor Number: TON) of 3 or less, and water hardness (Water Hardness) of 30 to 200 mg/L. hardness) may be 10 to 100 mg/L, potassium permanganate consumption may be 3 mg/L or less, and residual chlorine may be 0.4 mg/L or less.

Evaporation residue is what remains after evaporating water and is the content of minerals or organic matter floating or dissolved in water. Free carbonic acid is carbon dioxide gas dissolved in water, and when contained in large quantities, it can give a fresh taste and refreshing feeling like cider. Potassium permanganate consumption refers to the amount of organic matter, which is a carbon compound, exceeding the ability of microorganisms to decompose and purify organic matter. Residual chlorine is the amount of chlorine used for disinfection. If the concentration is high, the taste may be lost. Chlorine disinfection, which is used worldwide during water purification, is to ensure safety from microorganisms such as general bacteria and E. coli before sending water from the water purification plant to homes. In Korea, the law states that “residual chlorine in the faucet must be more than 0.1 mg / liter.” It is stipulated that Chlorine can be seen as an essential measure to ensure the safety of tap water. During the chlorine disinfection process, disinfection by-products such as chloroform and trihalomethane are generated. These are carcinogens and are strictly regulated by law in water quality standards. Water hardness indicates the content of calcium and magnesium.

This embodiment produces hydrogen peroxide using electrostatic spraying.

The average particle diameter of the water droplets of the reaction water sprayed from the needle 136 may be 10 nm to 200 μm. This is to ensure that the reaction water sprayed from the needle 136 by electrostatic spraying has a particle size of 20㎛ or less and is converted into fine droplets.

The diameter of the discharge port of the needle 136 is 4 mm or less so that the average particle diameter of the water droplets of the reaction water sprayed from the needle 136 is 10 nm to 200 μm. If the diameter of the discharge port of the needle 136 exceeds 4 mm, the average particle diameter of the water droplets may exceed 200 ㎛, and if the average particle diameter of the water droplets exceeds 200 ㎛, the concentration of hydrogen peroxide produced may be lowered.

For the electrostatic spraying effect, a positive (+) voltage is applied to the needle 136 that sprays reaction water, and a high negative (-) voltage is applied to the ground plate 137 spaced a predetermined distance away from the needle 136. can be approved.

Electrostatic spraying is a phenomenon in which the ions in the needle 136 and the reaction water are moved to the surface of the reaction water by repulsion and attraction, and when the Coulomb repulsion force exceeds the surface tension of the water droplets of the reaction water, the water droplets of the reaction water are converted into fine droplets and sprayed. means.

When the voltage between the needle 136 and the ground plate 137 is low, the electric force and the repulsion force of positive ions acting on the surface of the water droplets of the reaction water are smaller than the surface tension of the water droplets of the reaction water, so the water droplets of the reaction water are not sprayed, but the needle ( When a high voltage is applied between 136) and the ground plate 137, the electric force and the repulsion force of positive ions acting on the surface of the water droplets of the reaction water become greater than the surface tension of the water droplets of the reaction water, and the water droplets of the reaction water become fine droplets at the needle 136. It is sprayed.

At this time, when the average particle size of the water droplets of the reaction water decreases to submicron or less, some of the water droplets of the reaction water become as shown in [Formula 1] below and at the same time generate hydrogen peroxide as shown in [Formula 2] below. In other words, water droplets of reaction water are converted into fine droplets by electrostatic spraying, and ionized hydrogen ions (H ⁺ ) and hydroxide ions (OH ^- ) can react again to generate hydrogen peroxide.

[Formula 1]

H ₂ O-> H+ + OH-

[Formula 2]

O ₂ + 2H+ + 2e- -> H ₂ O ₂ , 2OH- + 2H+ -> H ₂ O ₂ + H ₂

This embodiment can effectively generate hydrogen peroxide using only reaction water and oxygen in the air using the electrostatic spray effect. Therefore, hydrogen peroxide can be produced without using additional chemicals such as conventional flammable hydrogen gas or retarded oxygen gas, expensive metal catalysts, and consuming a large amount of energy, thereby reducing costs.

In addition, when producing hydrogen peroxide using electrostatic spraying according to this embodiment, there is no risk of explosion such as heat generation, the process is simple, hydrogen peroxide can be produced on a large scale as well as on a small scale, and hydrogen peroxide can be produced right at the site where it is needed. Because it can be used, the transportation and storage costs of hydrogen peroxide can be reduced.

In addition, in the case of producing hydrogen peroxide using electrostatic spraying in this embodiment, hydrogen peroxide is stored together with reaction water such as water, and reaction water containing the stored hydrogen peroxide is supplied, so that it is used for sterilization in the electrostatic spray dust collection unit 130. You can utilize it.

In this embodiment, the amount of hydrogen peroxide produced in the reaction water per supply amount (ml/min) of reaction water sprayed from the needle 136 is set to be 0.001 ml/min to 0.05 ml/min.

For this purpose, the spray pressure of the reaction water sprayed from the needle 136 is 10 bar over 0 bar. If the spray pressure of the reaction water exceeds 10 bar, a short circuit may occur. Additionally, the supply amount of reaction water sprayed from the needle 136 is 0.01 ml/min or more. At a supply rate of less than 0.01ml/min, the amount of hydrogen peroxide produced may be reduced.

The separation distance between the needle 136 and the ground plate 137 may be 10 mm or more to prevent a short circuit between the needle 136 and the ground plate 137 while the reaction water is electrostatically sprayed. And, the applied voltage between the needle 136 and the ground plate 137 may be ±5kV. If the separation distance between the needle 136 and the ground plate 137 is less than 10 mm and the applied voltage is less than ±5 kV, the concentration of hydrogen peroxide generated may be lowered.

In this embodiment, the dehumidifying unit 140 may be configured as a fin-tube type heat exchanger.

At this time, the moisture that has condensed and fallen can be discharged to the outside and removed.

Since the outside air passing through the electrostatic spray dust collection unit 130 has very high humidity, when non-dehumidified outside air is introduced into the room, the room may become very humid, especially in summer.
