The present invention relates to a fine dust removing apparatus.

Electrostatic precipitator

[electric precipitation]

It is a device that cleans the gas by collecting the particles by electrostatic force, by applying an electric field to the gas, especially the dust floating in the air, to generate electricity. Depending on the method of removing the dust collected in the dust collector, there are kinds of wet and dry, and there are some vertical and horizontal depending on the gas flow.

For example, in an electric power plant, an electrostatic precipitator is installed during the gas flow to the chimney to remove a lot of dust, soot, etc. contained in the exhaust of the boiler. A DC voltage of tens of thousands of volts is required to collect electricity.

[Fig.] Shows the principle of dust collection. When a cylindrical dust collector is positive, a negative direct current high voltage is applied to the discharge line at the center of the cylinder, and then a gas containing dust is sent under the cylinder, So that the gas adhering to the inner surface of the cylinder and falling into the upper portion of the cylinder is cleaned. Dust accumulated in the cylinder is removed by washing it with water or mechanical shock to the cylinder.

The former is called wet type and the latter is called dry type dust collector . The gas flow is in a direction perpendicular to the horizontal direction. The former is suitable for a large amount of gas cleaning, the latter efficiently collecting dust, and has a small installation area. To make DC high voltage, use 50 or 60Hz AC power source to make 40,000 to 70,000 V by voltage regulator, special high-voltage transformer, rectifier and so on. The rectifier uses a high-pressure rectifier tube or a silicon rectifier . Regardless of which one is used, the method of limiting the overcurrent when the direct-current high-voltage side is short-circuited should be considered.

In the old method, a rectifying method using a mechanical synchronous relay as a rectifier was also used. The electrostatic precipitator is also referred to as a cotrel dust collector since F.G.

When the electrostatic precipitator is used, it refers to charging the particles by a corona discharge caused by a direct current high voltage and collecting dust using an electrostatic method by an electric field.

There is one stage and two stages. One stage is called cotrel system, which is formed by integrating discharge part and dust collecting part. Two stage type is mainly used for industrial and air purification, in which the discharge part and the dust collecting part are separate, , DC high voltage DC10 ~ 12KV and DC5 ~ 6KV are used.

Cotrrel electrostatic precipitator

F. G. It is a dust collector according to Cotrrel's invention. It is based on the principle that a charge of negative ionization is generated in the dust by the corona discharge and it is collected on the anode. Dust collecting from the exhaust of a cement factory, or dust collecting from a thermal power plant.

Electric dust precipitator

A device for separating charged particles from a gas by an electrostatic force by applying charges to particles in the tumbled gas using a corona discharge. For example, an electrostatic precipitator is installed in the gas flow to the chimney to remove much dust, soot, etc. contained in the boiler exhaust gas from the steam power plant. A DC voltage of tens of thousands of volts is required to collect electricity. The principle of the dust collector is to make the cylindrical dust collecting electrode positive and to apply a negative DC high voltage to the discharge line at the center of the cylinder, When a gas is sent from underneath, the dust adheres to the inner surface of the cylinder by negative charge, so that the gas falling into the upper part of the cylinder is cleaned. Dust accumulated in the cylinder is removed by washing it with water or mechanical shock to the cylinder. The former is called wet type and the latter is called dry type dust collector. The gas flow is in a direction perpendicular to the horizontal direction. The former is suitable for a large amount of gas cleaning, while the latter has an advantage that dust is efficiently collected and the installation area is small. To make DC high voltage, use AC power of 60Hz and make 40,000 to 70,000 V by voltage regulator, special high-voltage transformer, rectifier and so on. As a rectifier, a high-pressure rectifier tube or a silicon rectifier is used. In either case, a method of limiting the overcurrent when the direct-current high-voltage side is short-circuited should be considered. The electrostatic precipitator is also referred to as a cotrel dust collector since F. G. Cottrell has succeeded in industrial use. Abbreviations include EP, ESP, and so on.

Corona discharge [corona discharge sound, discharge]

If the voltage between the two electrodes in the gas is increased, a spark discharge occurs at a certain value. If the electric fields between the electrodes are not equal, a light emission phenomenon occurs in a portion where the electric field on the electrode surface is large before the spark discharge. Flows. This is called a corona discharge. In the portion where light is generated, ionization is actively performed, current density is large, and insulation is lost.

                         Corona discharge

Corona discharge [listen to corona discharge]

Summary: It is a form of gas discharge. When one or both of the electrodes are pointed, the electric field of the pole portion becomes stronger and discharge occurs, so that a discharge is generated in only a part between the poles, so that it is distinguished from the arc discharge.

When a high voltage is applied between the two electrodes, only a strong part of the electric field emits light before the flame is emitted, which is a conductive phenomenon. When the two electrodes are all flat or large spheres, the electric field is almost uniform. However, if one pole or the other is in the form of a rod or a needle, the electric field in the vicinity of the pole Particularly strong, it causes a partial discharge and emits light or sound. Such a state is called a corona discharge. Corona discharge causes corona loss. This discharge is a state in which a discharge is generated in a part between the poles and is different from an arc discharge in which the entire area between the poles is discharged.

The corona discharge occurs in DC voltage or AC voltage. The shape of the corona discharge varies depending on whether the pointed electrode is positive or negative. In the case of AC, the positive and negative corona Are alternately displayed. In the air, corona appears well, and when the pressure is lowered, it becomes increasingly unstable. High-voltage transmission lines can also cause corona, which causes radio disturbances. In order to prevent this obstacle, the structure of the wire and the insulator is improved to obtain the effect.

Corona discharge [listen to corona discharge]

As shown in the figure, when a direct current high voltage is applied between the plate electrode and the needle electrode, the gradient of the potential of the tip of the needle (intensity of the electric field) becomes large. When the voltage is increased, a local discharge accompanied by mischief and stray light occurs at the tip of the needle. This discharge is called a corona discharge, and the loss due to a discharge current is called a corona discharge.

Corona discharge

A local discharge phenomenon occurs only in a strong electric field when a strong inequality electric field is generated around the conductor.

The insulation of the air in the strong electric field is destroyed and discharged.

Silent discharge

Summary: No sound at discharge.

This is the corona discharge. A silent discharge occurs when a metal rod with a sharp end is connected to the whole of the main body or when a dielectric is inserted into a discharge path and an AC voltage is applied to both electrodes. It is used in discharge chemistry together with arc.

Rectifier [rectifier]

Summary: An electric circuit element or device made to concentrate rectification action to obtain DC power in AC power, and has the function of passing current only in one direction. Silicon diodes are used in most power supplies and thyristors are widely used in control rectifier applications.

It is a device or device that periodically converts an alternating current that changes in both positive and negative directions into a direct current having only one direction. The rectifier has a small forward resistance and a sufficiently large reverse resistance, so that it is possible to rectify the current only in one direction. In other words, it refers to a characteristic in which the forward direction in which the current flows smoothly and the reverse direction in which the current hardly flows are distinguished from each other in accordance with the direction of the applied voltage. A rectifier such as a diode can also be used for rectification, but for effective rectification, several devices are usually arranged on a specific circuit.

The electric current supplied by KEPCO is AC, and the electronic equipment we use is operated by DC, so all power supplies and electronic products contain rectifiers. The types used vary, but can be divided into semiconductor rectifiers, electron tube rectifiers, and mechanical rectifiers according to the principle of rectification action. The semiconductor rectifier has a rectifying action in the vicinity of a junction between a semiconductor and a metal or between two types of semiconductors, such as silicon, selenium, and copper oxide.

The potential barrier is composed of two terminals having a potential difference, and a potential barrier exists in a state where no voltage is applied near the junction. When the negative electrode of the power source is connected to the terminal having low potential and the positive electrode is connected to the terminal having high potential, the potential barrier is lowered and the current flows well. Inversely, when connected, the potential barrier increases and the resistance increases to infinity (reverse direction), so that the current does not flow. Through this process, only the current in one direction passes through the rectifier.

The tube rectifier applies the characteristic of the arc discharge. Electrons emitted from a cathode in a vacuum tube or a gas-filled discharge tube can go only to the anode according to the polarity of the applied voltage, so that only a one-sided current flowing from the anode to the cathode can be obtained. The mechanical rectifier achieves the purpose of rectification by using a contactor that is open or closed synchronously with the period of the AC power source or rotating. It has been known for a long time that metals are brought into contact with semiconductors and their rectification is exhibited, and they have been put to practical use as selenium rectifiers and copper oxide rectifiers.

A silicon rectifier is a rectifier circuit that combines a rectifier and consists of a transformer, a cooling device, and various protection devices. It has a simple structure and can be made compact and is easy to handle and has recently been used mainly. It has a long life, but it is weak in overload because of its small heat capacity. In the short term, it is possible to make several thousands of V · thousands of A capacitors, so that several of them can be combined in series and in parallel to produce tens of thousands of kW of rectifiers. A typical tube rectifier is a mercury rectifier and was widely used as a large power direct current power source until the 1950s, especially as a direct current power source for electric railway.

The thyristor is a silicon rectifier having a third electrode in addition to the anode and the cathode. Recently, a thyristor rectifier using a thyristor as a rectifier has been widely used in a control rectifier application part. Since the gate has a function similar to that of the mercury rectifier, the thyristor can rectify the constant AC voltage to obtain a variable DC voltage. By controlling the phase of the control current of the gate circuit, it is possible to control the voltage and current of the direct current so that it is widely used for the direct current constant voltage potential. Applications of gates have been increasingly applied to inverters that obtain alternating currents from a direct current and to choppers that obtain a variable direct current voltage from a constant direct current voltage.

 A rectifier is generally used when supplying a large amount of DC power from a power source for a chemical industry such as electrolysis or electroplating, or a power source for an electric railway. A rectifier is also used to sense the radio signal or to modulate the amplitude. If the signal is not amplified before sensing, use a diode with a very low voltage drop. A diode can be used to apply a polarized voltage when welding, and a bridge rectifier or thyristor can be used instead of a diode to control the output current.

Dust collector A device that recovers dust in the air, such as a cyclone or an electrostatic precipitator.

The centrifugal force collector (Cyclone)

It is a device that directly removes dust using centrifugal force (centrifugal force). Therefore, Cyclone, which is used as a pretreatment device for high-efficiency dust collectors, is used as a centrifugal force dust collector to exert reliable performance for dust removal of large dust particles.

Especially, it is possible to relatively reduce the price of the electrostatic precipitator itself, which is problematic in that it is excellent in design and manufacture as a pretreatment device for fine dust and requires a large installation cost. On the other hand, when used as a pretreatment device for a bag filter, the concentration of dust flowing into the follicle can be lowered, and the period of shaking off the dust can be lengthened, thereby prolonging the life of the filter. As such, the cyclone is not simply a low-performance device, and its own dust-collecting performance has played a large role in occupying the position as a pretreatment device.

Cyclone is the device that actually collects dust using centrifugal force. The gas introduced into the inlet of the centrifugal force collector is spirally rotated in the conical cylinder and the dust particles contained in the gas are separated from the gas at the inner wall of the cylinder or the inner wall of the conical cylinder by the centrifugal force, / RTI > Since the central portion of the conical cylinder is maintained at a negative pressure, the dust particles and the separated gas ascend to the top of the apparatus and are discharged.

Since the centrifugal force formed inside the device acts as an approximate value of 1,000 times or more of the weight of the dust particles, it is presumed that the particle size can be separated up to 5 μm, but in reality, complex secondary flow and turbulence are mixed in the cyclone Therefore, it is difficult to interpret the behavior of this flow analytically.

Cyclone

The air and dust absorbed by the cleaner are sent by centrifugal force to only the dust, and the air is discharged. It is divided into general type according to the suction power holding time, twin type in which air and far-away fat are separated, and multi type in which air and far-away fat are separated and dust is filtered twice.

SUMMARY OF THE INVENTION [0006]

If you look at the news story on TV January 24, 2017,

There are a lot of people who do Osechi so indoors, I will try to find out by experiment how much fine dust is generated during food .

Fine dust was measured with nationally approved equipment. Experts joined the experiment. All the food was cooked with canola oil which is often used for paprika.

The first food is the electric current such as the dongjinda and the tofu. In just five minutes from the start of the transfer, the fine dust concentration has exceeded 100 micrograms. It is above the atmospheric environment standard. So was ultrafine dust. I continued to add more.

"It's been 20 minutes since I cooked. I can see that fine dust has increased four times and super fine dust has increased five times."

This time, I drank early 'Bobbok' during the opening ceremony. Five minutes after the start of cooking , both fine dust and ultrafine dust exceeded three times the air quality standard.

After 15 minutes, the room was filled with smoke. Both fine dust and ultrafine dust poured over six times.

The last menu was pork belly . There are a lot of families who sit in the middle of their living room and sit around their families and bake their pork belly. The amount of fine dust generated was beyond my imagination . The air quality standard was poured 14 times . Ultrafine dust generation amounted to 7 times .

Experts point out that the more greasy the food, the more fine dust is produced.

Sohn Jong Ryul

"During the cooking process, the oil and the protein components in the fish are getting ripened, and fine particles and fine dust are generated. If you burn the food or make a lot of food at the same time,

Let's try cooking with squeezed olive oil. Let's check what the difference is. I measured the amount of fine dust generated by blowing 20 minutes ago. During the same time, we were able to confirm that fine dust and ultrafine dust, which were twice as much as ordinary cooking oil, were generated.

[anchor]

Is there any reason why olive oil causes more fine dust?

[reporter]

This is because the fume point is relatively low, which is the temperature at which the oil begins to boil and smoke begins to emerge. Extra virgin olive oil squeezed out of olive oil has a firing point of 180 degrees. It is the lowest level of edible oil sold on the market. So it is recommended to use mainly pressed or dressing in the case of pressed olive oil.

[anchor]

That means you have to use cooking oil to suit your needs. There is a reason why fine dust coming out from food is more dangerous.

[reporter]

That's right. The fine dust that comes out when cooking food contains carcinogens called PAH, consisting of more than 100 chemicals. Because of this, the World Health Organization (WHO) defines fine dust that occurs when cooking as a primary carcinogen .

[anchor]

It is the housewives who usually eat at home. If you watch this broadcast, you will be worried.

[reporter]

Indeed, we have seen women's lung cancer growth rates in the last 14 years . Women are four times more likely than men. In particular, 87% of women with lung cancer have never smoked in their lifetime. Eventually the food was damaged by fine dust It's likely . Let's listen to the expert.

Lim Young Wook

"There are many cases where people with low motions, such as pregnant women or those who like them, are pregnant, and pregnant women should know that they are weak and immune."

[anchor]

The Osechi is usually gathered in the living room like the experiment. I'm afraid there is more trouble because I can not ventilate.

[reporter]

That's right. So experts itgoyo recommended to write the fine dust masks come off when cooking. When we ventilate, we do not open the window, but if we open it to the front door, we can verify that the ventilation is enough even if it is opened for only about 3 minutes . So, after 15 minutes of cooking, you should open the front door and let it ventilate for 3 minutes or more.

Solving the problem of noise and suction capacity of a vacuum cleaner

And to provide a device for removing fine dust when cooking.

However, since the fine holes of the filter are clogged by dust or the like, the suction force is reduced. Therefore, the noise problem and the reduction of air suction force are problems to be solved by the present invention.
