Description

hydrogen generation system

The present invention relates to a hydrogen production system, and more specifically, to a hydrogen production system capable of producing hydrogen in an environmentally friendly manner.

In order to solve the problem of global warming and accelerating climate change, interest in technologies that produce and utilize eco-friendly energy to reduce greenhouse gases is increasing around the world.

As eco-friendly energy, renewable energy such as solar and wind power has the advantage of being environmentally friendly and infinite, but has problems such as intermittency of power generation and system stabilization.

To address these problems, hydrogen is attracting attention as a complementary material to renewable energy, and many countries are announcing various policies to expand the hydrogen economy.

The hydrogen economy refers to an economy in which hydrogen becomes a source of economic growth and eco-friendly energy by using hydrogen as an important energy source to bring about fundamental changes in the national economy and people's lives.

In order to revitalize the hydrogen economy, technology development efforts are needed across the entire hydrogen economy cycle, including production, storage, transportation, and utilization. As a first step, hydrogen production technology to secure and supply sufficient hydrogen is important.

Raw materials used to produce hydrogen include fossil fuels, water, biomass, and waste resources, and energy sources include heat and electricity. Additionally, representative hydrogen production methods include byproduct hydrogen method, reformed hydrogen method, and water electrolysis method.

The byproduct hydrogen method uses hydrogen produced incidentally through a chemical reaction in a petrochemical or steel manufacturing process.

This method has the advantage of being highly economical as there is no additional facility investment cost for hydrogen production because it uses waste gas. However, there is a limit to production because it uses hydrogen generated as a by-product, and its low purity requires a high purity process to be utilized. There is a problem of necessity.

The reformed hydrogen method produces hydrogen through a catalytic reaction using hydrocarbon fossil fuels such as natural gas, coal, and oil.

Currently, most hydrogen produced around the world is hydrogen produced through fossil fuel reforming. However, the method of producing hydrogen through fossil fuel reforming has the problem of accompanying carbon dioxide emissions.

Water electrolysis is a water decomposition method caused by an electrochemical reaction that generates hydrogen by applying electricity to water. Depending on the electrolyte, water electrolysis methods include alkaline water electrolysis (AECl), polymer electrolyte water electrolysis (PEMECl), and solid oxide water electrolysis (SOECl).

Producing hydrogen through water electrolysis based on renewable energy is environmentally friendly because it does not generate carbon dioxide, but the current method has the problem of poor economic feasibility.

Hereinafter, the hydrogen production system according to the present invention will be described in detail with reference to the drawings.

As shown in the drawing, the hydrogen generation system 10 according to an embodiment of the present invention includes a processing device 100 that processes fluid for hydrogen generation, and electrical characteristics of the fluid processed in the processing device 100. It includes a connecting device 210 configured to change the fluid, and a hydrogen generating device 300 that receives fluid through the connecting device 210 and extracts hydrogen from the fluid. The processing device 100 and the connecting device 210 may be connected through a connecting pipe 420, and the connecting device 210 and the hydrogen generating device 300 may be connected through another connecting pipe 430. A valve 500 may be installed between the connection device 210 and the hydrogen generation device 300 to regulate the flow of fluid supplied from the connection device 210 to the hydrogen generation device 300. The valve 500 may be a manual valve or an automatic valve.

The processing device 100 receives fluid from a fluid supply device (not shown) through the supply pipe 410, generates plasma in the fluid by frictionally charging the flowing fluid without an external power source or electrode, and chemically decomposes the fluid through this. It can be processed.

Processing device 100 can process various fluids. For example, the treatment device 100 according to an embodiment of the present invention processes water to produce a large amount of hydronium ions (H ₃ O ⁺ ), hydrogen nano-bubbles (for example, 65 nm in diameter or less), and Plasma activated water containing oxygen nano-bubbles (for example, diameter 65 nm or less) can be generated. The water supplied to the treatment device 100 may be water that has been pretreated to remove foreign substances and have low electrical conductivity.

As shown in FIGS. 2 to 5 , the processing device 100 includes an external body 110, a screw 130 accommodated inside the external body 110, and a guide assembly 140.

The external body 110 is hollow to accommodate the screw 130 and the guide assembly 140. A through hole 111 is formed inside the outer body 110, penetrating the outer body 110 in the longitudinal direction. The through hole 111 may form a fluid flow path through which fluid can flow. A screw 130 and a guide assembly 140 are accommodated in the through hole 111. Additionally, at least a portion of the connecting tube 160 for guiding fluid to the screw 130 may be accommodated in the through hole 111 .

The portion of the through hole 111 between the guide assembly 140 and the connecting tube 160 forms an entry passage 115 that connects the guide assembly 140 and the connecting tube 160 so that fluid can flow. , a screw 130 is disposed in the entry passage 115. Additionally, another portion of the through hole 111 forms a discharge passage 113 through which fluid passing through the guide assembly 140 can flow. The discharge passage 113 is wider than the passages provided in the guide assembly 140.

A ledge 118 is provided on the inside of the external body 110 to limit the movement of the guide assembly 140. The ledge 118 protrudes from the inner surface of the outer body 110. The ledge 118 may restrict the movement of the guide assembly 140 by contacting the end of the guide assembly 140 to prevent the guide assembly 140 from moving in the fluid flow direction A. The ledge 118 may be ring-shaped or in various other shapes that may contact the end of the guide assembly 140.

The ledge 118 includes an enlarged portion 120 and a contact portion 122. The contact portion 122 is disposed upstream of the enlarged portion 120 based on the fluid flow direction A so as to contact the guide assembly 140.

The enlarged portion 120 has a curved shape whose diameter gradually increases in a direction away from the end of the guide assembly 140. A first enlarged part connection part 120a and a second enlarged part connection part 120b are provided at both ends of the enlarged part 120, respectively. The first enlarged part connection part 120a is disposed upstream of the second enlarged part connection part 120b based on the fluid flow direction A. The first enlarged portion connection portion 120a may be formed in a convex curved shape with a constant radius of curvature. The second enlarged portion connection portion 120b may be formed in a concave curved shape with a constant radius of curvature. The radius of curvature of the first enlarged portion connecting portion 120a and the radius of curvature of the second enlarged portion connecting portion 120b may be the same or different. The second enlarged portion connection portion 120b may be connected to the inner surface of the external body 110 that borders the discharge passage 113 at a gentle slope.

The enlarged portion 120 may form a flow path that expands at a gentle inclination angle between the guide assembly 140 and the discharge flow path 113. If there is a corner on the inner surface of the external body 110 in contact with the fluid, a problem may occur where electric charges are concentrated at the corner. The fluid processing device 100 according to the present invention is provided with an enlarged portion 120 between the guide assembly 140 and the discharge passage 113, so that electric charges are concentrated between the guide assembly 140 and the discharge passage 113. , the problem of the external body 110 or the guide assembly 140 being damaged or broken due to concentration of electric charges can be reduced.

The contact portion 122 has a shape whose inner diameter is gradually reduced along the flow direction of the fluid so as to stably contact the guide assembly 140. A first contact connection portion 122a and a second contact connection portion 122b are provided at both ends of the contact portion 122, respectively. The first contact connection portion 122a is disposed upstream of the second contact connection portion 122b based on the fluid flow direction A. The first contact connection portion 122a may be formed in a concave curved shape with a constant radius of curvature. The second contact connection portion 122b may be formed in a convex curved shape with a constant radius of curvature. For example, the first contact connection part 122a may be formed in a curved shape with an arbitrary first radius of curvature, and the second contact connection part 122b may be formed in a curved shape with an arbitrary second radius of curvature. The first radius of curvature and the second radius of curvature may be the same or different.

The outer body 110 is made of an insulating material. For example, the external body 110 may be made of synthetic resin materials such as acrylic and engineering plastic, or various dielectric materials.

The screw 130 is disposed upstream of the guide assembly 140 based on the fluid flow direction A, and can rotate the fluid to flow into the guide assembly 140. The screw 130 is preferably made of a material that is easily frictionally charged with a negative charge, that is, a material that can frictionally charge a fluid with a positive charge. For example, the screw 130 may be made of synthetic resin materials such as acrylic and engineering plastic, or various dielectric materials.

The screw 130 has blades 131 for generating vortices in the fluid. The blade 131 may be shaped to generate a vortex by rotating the fluid. Accordingly, the fluid passing through the blade 131 may flow while swirling. When the fluid quickly passes through the screw 130, a cavitation phenomenon occurs due to a rapid change in fluid pressure, which causes fine bubbles (B, for example, 50 μm in diameter or less) to be generated in the fluid. Additionally, the fluid may be frictionally charged with a positive charge when it quickly passes through the screw 130. The screw 130 may be referred to as a vortex guide.

The screw 130 enters between the guide assembly 140 and the connecting tube 160 in various ways, such as being press-fitted into the external body 110 or fixed between the guide assembly 140 and the connecting tube 160. It may be fixed to the flow path 115. Accordingly, the screw 130 can rotate the fluid without rotating. When the screw 130 is rotated by the flowing fluid, the friction charging efficiency between the fluid and the screw 130 may decrease. On the other hand, the fluid processing device 100 according to an embodiment of the present invention guides the fluid with the screw 130 fixed, thereby increasing the friction charging efficiency of the fluid.

In the drawing, the screw 130 is shown as having a diameter corresponding to the diameter of the entry passage 115, but the screw 130 may have a diameter smaller than the diameter of the entry passage 115.

The guide assembly 140 is located downstream of the screw 130 based on the fluid flow direction (A). The guide assembly 140 may provide a first flow path 156 and a second flow path 158 through which fluid passes. In this specification, the first flow path 156 may be referred to as a bubble forming flow path 156, and the second flow path 158 may be referred to as a reaction flow path 158. The bubble forming flow path 156 is configured to form bubbles B in the fluid flowing along it. The reaction passage 158 is configured to collapse bubbles B contained in the fluid flowing along it. The first flow path 156 is disposed upstream of the second flow path 158 based on the fluid flow direction (A).

The guide assembly 140 includes a first guide 141 and a second guide 145. The first guide 141 and the second guide 145 are sequentially arranged along the fluid flow direction A. The first guide 141 and the second guide 145 are preferably made of a material that is easily charged with a negative charge, that is, a material that can frictionally charge the fluid with a positive charge. For example, the first guide 141 and the second guide 145 may be made of synthetic resin materials such as acrylic and engineering plastic, or various dielectric materials.

The first guide 141 may be in contact with the screw 130 or disposed adjacent to the screw 130 to allow fluid passing through the screw 130 to flow in. The first guide 141 includes a focusing flow path 142 and an inlet flow path 143. The focusing flow path 142 has a shape whose diameter gradually decreases along the fluid flow direction (A). The focusing flow path 142 may guide the fluid passing through the screw 130 to the inlet flow path 143. That is, the fluid may flow along the focusing flow path 142 and be concentrated in the inlet flow path 143. The inlet flow path 143 is connected to the focusing flow path 142 so that fluid flows in from the focusing flow path 142. The inlet flow path 143 is narrower than the focusing flow path 142, so the friction charging effect can be increased by increasing the flow rate of the fluid. At the portion where the focusing flow path 142 and the inlet flow path 143 are connected, the diameter of the focusing flow path 142 and the diameter of the inlet flow path 143 are the same.

The first guide 141 may provide a first flow path 156. That is, the focusing passage 142 and the inlet passage 143 of the first guide 141 form the first passage 156 together with the entry passage 115 that accommodates the screw 130. The fluid may flow while generating a vortex in the first flow path 156, and may be frictionally charged with a positive charge due to friction with the screw 130 and the first guide 141. At this time, the screw 130 and the first guide 141 may be negatively charged. Additionally, when the fluid passes through the first flow path 156, fine bubbles B are generated in the fluid due to cavitation. In addition, when the fluid passes through the first passage 156, the fluid is positively charged, and negative charges are concentrated at the interface of the bubbles (B) generated in the fluid. When the fluid passes through the first passage 156, the fluid Although a large amount of bubbles B are generated in the fluid, the area where bubbles B are generated in the fluid is not limited to the first flow path 156. That is, even when the fluid passes through the second flow path 158, bubbles B may be generated in the fluid.

The second guide 145 may be in contact with the first guide 141 or may be disposed adjacent to the first guide 141 to allow fluid that has passed through the first guide 141 to flow in. The second guide 145 has an expanded flow path 146, a reduced flow path 147, and a connecting flow path 148.

The expansion flow path 146 is connected to the inlet flow path 143 of the first guide 141. Fluid passing through the inlet flow path 143 flows into the expansion flow path 146. The diameter of the expansion flow path 146 is larger than the diameter of the inlet flow path 143. The pressure of the fluid that has passed through the narrow inlet passage 143 flows into the expansion passage 146, and the bubbles B in the fluid may expand in the expansion passage 146.

The reduced flow path 147 is connected to the expanded flow path 146. The diameter of the reduced flow path 147 is smaller than the diameter of the expanded flow path 146. Accordingly, the pressure of the fluid that has passed through the expansion passage 146 flows into the reduction passage 147, and the bubbles B in the fluid may shrink in the reduction passage 147. The connection flow path 148 connects the reduction flow path 147 and the discharge flow path 113.

The connection flow path 148 is connected to the reduction flow path 147. The connection passage 148 has a diameter whose diameter gradually expands along the fluid flow direction (A). The connection passage 148 has a diameter of the portion connected to the reduction passage 147 that is the same as the diameter of the reduction passage 147, and the diameter of the portion connected to the discharge passage 113 is larger than the diameter of the reduction passage 147. . In addition, the diameter of the portion of the connection passage 148 connected to the discharge passage 113 is smaller than the diameter of the discharge passage 113. The connection passage 148 has a shape that gradually expands from the reduction passage 147 toward the discharge passage 113, so that the fluid passing through the reduction passage 147 can be more smoothly discharged into the discharge passage 113. .

The second guide 145 is provided with an inclined portion 152 corresponding to the contact portion 122 of the external body 110. The inclined portion 152 is provided on the outer surface of the second guide 145 in a shape whose outer diameter gradually decreases along the fluid flow direction A. A first inclined portion connection portion 152a and a second inclined portion connecting portion 152b are provided at both ends of the inclined portion 152, respectively. The first inclined portion connection portion 152a is disposed upstream of the second inclined portion connecting portion 152b based on the fluid flow direction (A). The first inclined portion connection portion 152a may be formed in a convex curved shape with a constant radius of curvature. The second inclined portion connection portion 152b may be formed in a concave curved shape with a constant radius of curvature. For example, the first inclined portion connection portion 152a is formed in a curved shape with a first radius of curvature like the first contact portion connecting portion 122a of the contact portion 122, and the second inclined portion connecting portion 152b is a contact portion ( Like the second contact connection portion 122b of 122), it may be formed in a curved shape with a second radius of curvature. Since the first inclined portion connecting portion 152a has the same radius of curvature as the first contact connecting portion 122a, the first inclined portion connecting portion 152a can stably contact the first contact connecting portion 122a. Additionally, since the second inclined portion connection portion 152b has the same radius of curvature as the second contact portion connecting portion 122b, the second inclined portion connecting portion 152b can stably contact the second contact portion connecting portion 122b.

The radius of curvature of the first inclined portion connection portion 152a or the second inclined portion connecting portion 152b may vary depending on the radius of curvature of the first contact portion connecting portion 122a or the second contact portion connecting portion 122b.

A curved round part 154 is provided around the edge of the end of the second guide 145 adjacent to the enlarged part 120 of the external body 110. If there is a sharp edge at the end of the guide assembly 140, a problem may occur where electric charges are concentrated on the edge. Therefore, by providing the round portion 154 around the end edge of the second guide 145, charges are concentrated at the end of the second guide 145, or the second guide 145 is damaged due to the concentration of charges. Damage problems can be reduced.

The second guide 145 may provide a second flow path 158 whose diameter is enlarged in at least some sections so that a rapid change in pressure of the fluid can occur. That is, the expanded flow path 146 and the contracted flow path 147 of the second guide 145 form the second flow path 158. The expansion flow path 146 may form an enlarged diameter section in the second flow path 158. When the fluid passes through the second flow path 158, a rapid change in pressure of the fluid may occur, and the bubbles B in the fluid may collapse.

When fine bubbles (B) with a high density of negative charges at the interface collapse in large quantities in a positively charged fluid, plasma at high temperature (e.g., 12,000 to 14,000 K) and high pressure (e.g., 3,200,000 bar) is generated. do. Additionally, the fluid may be ionized or decomposed due to the plasma generated within the fluid. In other words, substances constituting the fluid may be chemically decomposed by plasma generated in the fluid.

When the fluid passes through the second flow path 158, a large amount of bubbles B in the fluid collapse, but the area where the bubbles B collapse is not limited to the second flow path 158. That is, collapse of the bubbles B may occur in at least a partial area of the first flow path 156 or a partial area of the discharge flow path 113.

The fluid processing process by the fluid processing device 100 is as follows.

The fluid supplied to the processing device 100 through the supply pipe 410 passes through the screw 130. Fluid flowing quickly along the blade 131 of the screw 130 generates a vortex. At this time, a cavitation phenomenon occurs due to a rapid change in fluid pressure, which causes fine bubbles (B) to be generated in the fluid. The fluid passing through the screw 130 generates a vortex and sequentially passes through the focusing flow path 142 and the inlet flow path 143 of the first guide 141. At this time, the fluid is frictionally charged with positive charges, and negative charges are concentrated at the interface of the bubbles (B) in the fluid.

In this way, the fluid in which bubbles B are generated while passing through the bubble forming flow path 156 flows into the second flow path 158, that is, the reaction flow path 158, causing a rapid change in pressure.

Specifically, the fluid that has passed through the bubble forming flow path 156 first flows into the expansion flow path 146 and its pressure is rapidly lowered. The bubbles B in the fluid may expand in the expansion passage 146. Subsequently, the pressure of the fluid that has passed through the expansion passage 146 flows into the reduction passage 147 and rapidly increases. The bubbles B in the fluid may be reduced in the reduction flow path 147.

In this way, the fluid causes a rapid change in pressure as it sequentially passes through the expansion flow path 146 and the contraction flow path 147 forming the reaction flow path 158. Accordingly, while the bubbles B in the fluid pass through the reaction passage 158, they undergo expansion and contraction processes and collapse in large quantities. And, when a large number of bubbles (B) collapse, a discharge phenomenon occurs due to positive and negative charges in the fluid, thereby generating plasma in the fluid. At this time, since plasma is accompanied by light, high heat, and high pressure, the fluid may be ionized or decomposed.

The fluid treated with plasma in this way flows to the connection device 210 through the connection pipe 420.

Referring again to FIG. 1, the connection device 210 connects the processing device 100 and the hydrogen generation device 300 and is configured to change the electrical characteristics of the fluid as it passes through. Connecting device 210 includes a buffer tank 212 that can store treated fluid from processing device 100 . The buffer tank 212 has a storage space 214 capable of storing fluid. The buffer tank 212 is made entirely or partially of a conductive material and is configured to be grounded to the ground portion (G). Accordingly, the buffer tank 212 can ground the fluid contained therein to the ground portion (G). That is, the buffer tank 212 can lower the electrical potential of the fluid by releasing electrons or charges of the fluid to the outside of the storage space 214.

The connection device 210 can store the fluid for a preset time to lower the electrical potential of the fluid and then supply it to the hydrogen generation device 300. For example, after valve 500 is controlled to block the flow of fluid through connector 430, fluid may be supplied to buffer tank 212 at a preset level. And after the electrical potential of the fluid stored in the buffer tank 212 is lowered below a preset level, the valve 500 is controlled to open so that the fluid can be supplied to the hydrogen generating device 300.

When the fluid passes through the processing device 100, the fluid is positively charged by friction charging, so the electrical potential of the fluid is high. Therefore, when the fluid is directly supplied from the processing device 100 to the hydrogen generating device 300, A discharge phenomenon may occur in the hydrogen generation device 300 or various electronic devices or sensors connected to the hydrogen generation device 300, which may cause the hydrogen generation device 300 to malfunction or be damaged. The connection device 210 supplies the fluid to the hydrogen generating device 300 after sufficiently lowering the electrical potential of the fluid, thereby preventing such problems.

If the connection device 210 has excellent efficiency in releasing electrons or charges in the fluid and can sufficiently prevent the discharge phenomenon, the connection device 210 connects the fluid supplied from the processing device 100 to the buffer tank 212. It may be configured to supply directly to the hydrogen generation device 300.

Hydrogen generation device 300 is configured to extract hydrogen from a fluid. The hydrogen generation device 300 includes a separation membrane 310 for separating hydrogen from a fluid, a first discharge pipe 320 for discharging hydrogen, and discharging the fluid from which the hydrogen has been separated or the remaining material from which the hydrogen has been separated from the fluid. It includes a second discharge pipe 330 for. As the separation membrane 310, various types of membranes capable of separating hydrogen, such as a polymer electrolyte membrane (PEM), may be used.

Since hydrogen extraction technology using a separation membrane is known, a detailed description of the hydrogen generation device 300 will be omitted.

Below, a process in which the hydrogen generation system 10 according to an embodiment of the present invention generates hydrogen by receiving water from which minerals or dissolved gases have been removed will be described.

When the fluid processing device 100 is supplied with water, the fluid processing device 100 may treat the water into water rich in hydronium ions and hydrogen nanobubbles.

The water supplied to the fluid processing device 100 is preferably pretreated water or ultrapure water with foreign substances removed to have low electrical conductivity and high electrical resistance. Ultrapure water is water that has relatively high electrical resistance because minerals and dissolved gases have been removed. As water with high electrical resistance passes through the fluid processing device 100, less discharge of electric charge occurs before plasma is generated. In addition, water with high electrical resistance generates less discharge of electric charge before plasma generation, so a more powerful plasma can be induced, and thus can be treated more efficiently.

When high-pressure water is supplied to the fluid processing device 100, a large amount of fine bubbles (B) are generated in the water according to the same principle as described above, and these bubbles (B) collapse to generate plasma. Additionally, water molecules are decomposed through chemical decomposition and ionization reactions due to the high temperature and pressure accompanying plasma generation, generating H+ ions and OH- ions. Additionally, a large amount of OH- ions may be decomposed into hydrogen and oxygen due to the high temperature and pressure caused by plasma generation. According to this chemical decomposition reaction of water molecules, a large amount of hydronium ions (H ₃ O ⁺ ), a large amount of hydrogen nano-bubbles (e.g., diameter 65 nm or less) and oxygen nano-bubbles (e.g., diameter 65 nm or less) ) is created.

Water treated in the treatment device 100 flows into the buffer tank 212 through the connection pipe 420, and the water flowing into the buffer tank 212 is grounded to the ground portion (G), thereby lowering the electrical potential. Water whose electrical properties have been changed by the connecting device 210 is supplied to the hydrogen generating device 300 through the connecting pipe 430.

The hydrogen generation device 300 can extract hydrogen from water using the separation membrane 310. Hydrogen extracted by the separation membrane 310 may flow into a hydrogen storage device (not shown) through the first discharge pipe 320.

Since the hydrogen generation device 300 is supplied with water that has been treated by the treatment device 100 to contain a large amount of hydronium ions and oxygen and hydrogen nano-bubbles, a larger amount of hydrogen can be extracted from the water.

In addition, water treated by the treatment device 100 to contain a large amount of hydronium ions and oxygen and hydrogen nano-bubbles can increase the hydrogen extraction efficiency of the separation membrane 310, making the hydrogen generation device 300 more efficient. It can produce large amounts of hydrogen.

For example, when a polymer electrolyte membrane is used as the separator 310, the catalyst of the polymer electrolyte membrane can be reduced and activated by the excellent reducing power of H2 present in nanobubbles created in water. Additionally, the hydrogen extraction performance of the polymer electrolyte membrane can be improved by activating the catalyst.

As described above, the hydrogen generation system 10 according to an embodiment of the present invention chemically decomposes and ionizes the fluid in an electrodeless manner using the fluid processing device 100, and uses the connection device 210 to After lowering the electrical potential, hydrogen can be extracted from the fluid using the hydrogen generating device 300. Therefore, hydrogen can be produced in an environmentally friendly manner without the need for a fluid electrolysis process.

Here, the electrodeless method of the fluid processing device 100 uses the energy generated when the bubbles (B) in the fluid collapse to ionize or ionize the fluid without the need for an electrode to apply electrical energy to the bubbles (B) in the fluid. It may mean a method of decomposition. The fluid processing device 100 generates a large amount of fine bubbles (B) using the cavitation phenomenon of the flowing fluid, and collapses a large amount of the fine bubbles (B) with negative charges concentrated at the interface to generate plasma by discharge of the charge, thereby generating a large amount of fine bubbles (B) using the cavitation phenomenon of the flowing fluid. Can be chemically decomposed or ionized. In other words, the fluid can be ionized or decomposed in an electrodeless manner by collapsing a large number of fine bubbles (B) with a high negative charge density at the interface in a positively charged fluid to generate high temperature and high pressure plasma. Therefore, the fluid can be ionized or decomposed without an external power source or electrode, and the fluid can be efficiently treated with little energy.

The specific configuration of the fluid processing device 100 is not limited to the form described and shown above.

For example, the specific configuration of the guide assembly 140 for providing the bubble forming flow path 156 and the reaction flow path 158 may be changed in various ways.

The interior of the external body 110 is provided with a discharge passage 113 through which fluid passing through the fourth body 640 flows. The discharge passage 113 is disposed downstream of the fourth body 640 based on the fluid flow direction (A).

The specific configuration of the external body 110 is the same as described above.

The first body 610 includes a screw 130 and a first guide 141.

The screw 130 is disposed upstream of the first guide 141 based on the fluid flow direction A, and can rotate the fluid to flow into the first guide 141. The screw 130 has blades 131 for generating vortices in the fluid.

The second body 620 may be in contact with the first guide 141 or may be disposed adjacent to the first guide 141 so that the fluid that has passed through the first guide 141 flows in. The second body 620 has a second fluid flow path 621. Fluid passing through the first fluid passage 611 of the first body 610 flows into the second fluid passage 621. The diameter of the second fluid flow path 621 is larger than the diameter of the inlet flow path 143. The pressure of the fluid that has passed through the narrow inlet passage 143 flows into the second fluid passage 621, and the bubbles B in the fluid may expand in the second fluid passage 621.

The third body 630 may be in contact with the second body 620 or may be disposed adjacent to the second body 620 so that fluid passing through the second body 620 flows in. The third body 630 has a third fluid passage 631. The diameter of the third fluid passage 631 is smaller than the diameter of the second fluid passage 621. Accordingly, the pressure of the fluid passing through the second fluid passage 621 increases as it flows into the third fluid passage 631, and the bubbles B in the fluid may shrink in the third fluid passage 631.

The third body 630 is made of a material with higher electrical conductivity than the first body 610, the second body 620, and the fourth body 640. For example, the third body 630 may be made of metal. The third body 630 may function as a storage body for storing negative charges. Additionally, the third body 630 may promote the collapse of bubbles B contained in the fluid. That is, the third body 630 stores negative charges and applies a repulsive force to the bubbles B with negative charges concentrated at the interface, thereby promoting the collapse of the bubbles B.

Additionally, the third body 630 can promote the collapse of the bubbles B with negative charges concentrated at the interface by forming an electric field in the fluid.

Additionally, the third body 630 can induce plasma to be stably generated along the center of the reaction passage 652 by concentrating the bubbles B in the center of the reaction passage 652 through repulsion.

As such, the third body 630 has a function of promoting the collapse of the bubbles B, and may be called an accelerator or a metal insert.

The connection passage 643 has a diameter of the portion connected to the reduction passage 642 that is the same as the diameter of the reduction passage 642, and the diameter of the portion connected to the discharge passage 113 is larger than the diameter of the reduction passage 642. . Additionally, the diameter of the connection passage 643 connected to the discharge passage 113 is smaller than the diameter of the discharge passage 113. The connection passage 643 has a shape that gradually expands from the reduction passage 642 toward the discharge passage 113, so that the fluid passing through the reduction passage 642 can be more smoothly discharged into the discharge passage 113. .

The inner surface of the fourth body 640 is provided with an inclined surface 644 that is inclined with respect to the center line of the connection passage 643 to border the circumference of the connection passage 643.

The first inclined portion connection portion 645a may be formed in a convex curved shape with a constant radius of curvature. The second inclined portion connection portion 645b may be formed in a concave curved shape with a constant radius of curvature. For example, the first inclined portion connection portion 645a is formed in a curved shape with a first radius of curvature like the first contact portion connecting portion 122a of the contact portion 122, and the second inclined portion connecting portion 645b is a contact portion ( Like the second contact connection portion 122b of 122), it may be formed in a curved shape with a second radius of curvature.

A curved round part 647 is provided around the edge of the end of the fourth body 640 adjacent to the enlarged part 120 of the external body 110. By providing a round portion 647 around the end edge of the fourth body 640, charges are concentrated at the end of the fourth body 640, or the fourth body 640 is damaged or damaged due to the concentration of charges. Problems can be reduced.

The fluid processing process by the fluid processing device 600 according to this embodiment is as follows.

High-pressure fluid flowing into the interior of the external body 110 through the supply pipe 410 first passes through the screw 130. Fluid flowing quickly along the blade 131 of the screw 130 generates a vortex. At this time, a cavitation phenomenon occurs due to a rapid change in fluid pressure, which causes fine bubbles (B) to be generated in the fluid. The fluid passing through the screw 130 generates a vortex and sequentially passes through the focusing flow path 142 and the inlet flow path 143 of the first guide 141. At this time, the fluid is frictionally charged with positive charges, and negative charges are concentrated at the interface of the bubbles (B) in the fluid.

As the fluid that has passed through the first guide 141 flows into the second fluid passage 621 of the second body 620, its pressure suddenly decreases. Bubbles B in the fluid may expand in the second fluid passage 621. Subsequently, the fluid that has passed through the second fluid passage 621 flows into the third fluid passage 631 of the third body 630 and the reduced passage 642 of the fourth body 640, and the pressure rapidly increases. I do it.

In this way, the fluid passing through the second fluid passage 621, the third fluid passage 631, and the contraction passage 642 causes a rapid change in pressure, and the bubbles B in the fluid undergo expansion and contraction processes. collapses in large quantities. At this time, the third body 630 applies a repulsive force to the bubbles B in the fluid, thereby promoting the collapse of the bubbles B. As bubbles (B) in the fluid collapse in large quantities, plasma is generated in the fluid, and the fluid may be ionized or decomposed by plasma generation.
