Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above prior art, in order to promote the contact between the exhaust gas (liquid) and the cleaning water (liquid), a contact promoting filler must be provided, which has the disadvantages of increasing the size of the equipment and increasing the cost. By the way, as a method for efficiently bringing the exhaust gas (gas) into contact with water (liquid), for example, it is conceivable to mix the exhaust gas (gas) with water (liquid) that has been miniaturized into fine particles. By using such a method, without providing a contact promoting filler, while achieving compactification of the equipment and cost reduction, it is advantageous for efficiently mixing the exhaust gas (gas) and water (liquid). In addition, various effects can be expected by efficiently mixing a gas and particles of atomized liquid. For example, it is conceivable that ethanol gas can be efficiently generated by mixing particles of atomized ethanol (liquid) and air (gas). The present invention has been made in view of the above circumstances, and an object thereof is to provide a spiral atomization device for a liquid that is advantageous in efficiently mixing a gas and particles of atomized liquid with a simple configuration.

Means for Solving the Problems

[0005] The present invention is a spiral atomization device for a liquid, comprising: an outer cylinder portion that is elongated, provided with a gas inlet through which a gas is introduced at one end in the longitudinal direction, and a gas outlet through which the gas is discharged at the other end in the longitudinal direction; a rotating cylinder portion that extends along the outer cylinder portion inside the outer cylinder portion and is rotatably supported; a plurality of injection nozzles that are provided at intervals along a spiral locus on the outer peripheral surface of the rotating cylinder portion and whose injection ports communicate with the inside of the rotating cylinder portion; a liquid supply portion that supplies liquid to the inside of the rotating cylinder portion and injects the liquid from the plurality of injection nozzles; a rotation driving portion that rotates the rotating cylinder portion so that the gas is guided from the gas inlet to the gas outlet by the liquid injected from the plurality of injection nozzles; and a liquid outlet that is provided at a location of the outer cylinder portion near the gas outlet and discharges the liquid flowing on the inner surface of the outer cylinder portion to the outside of the outer cylinder portion.

Effects of the Invention

[0006] According to the present invention, with a simple configuration such as rotating a rotating cylinder portion provided with a plurality of injection nozzles inside an outer cylinder portion, the gas introduced into the outer cylinder portion is mixed with particles of atomized liquid by colliding with each other when injected from the plurality of injection nozzles or colliding with the inner peripheral surface of the outer cylinder portion, which is advantageous for efficiently mixing the gas and the liquid particles. In addition, a plurality of injection nozzles are provided at intervals along a spiral locus on the outer peripheral surface of the rotating cylinder portion, and the rotating cylinder portion is rotated so that the gas is guided from the gas inlet to the gas outlet by the liquid injected from the plurality of injection nozzles. Therefore, it is advantageous in efficiently guiding the gas from the gas inlet to the gas outlet by the liquid injected from the plurality of injection nozzles.

Embodiments for Carrying Out the Invention

[0008] (First Embodiment) Next, a liquid spiral type miniaturization device (hereinafter referred to as a spiral type miniaturization device) according to an embodiment of the present invention will be described with reference to the drawings. In the first embodiment, a case where the spiral type miniaturization device is configured as an exhaust gas purification device that purifies exhaust gas as a gas using water as a liquid will be described. As shown in FIG. 1, the spiral type miniaturization device 10A includes an outer cylinder portion 12, a rotating cylinder portion 14, a plurality of injection nozzles 16, a liquid supply portion 17, and a rotation drive portion 18.

[0009] The outer cylinder part 12 includes a straight part 20 presenting an elongated cylindrical shape extending linearly, and a curved part 22 connected to the end of the straight part 20 and curved downward with respect to the straight part 20, and is fixed to the floor surface via a frame (not shown). The curved part 22 includes a base part 23 curved with substantially the same inner and outer diameters as the straight part 20, and a reduced-diameter part 24 provided at the tip of the base part 23 and formed such that the cross-sectional area gradually decreases and the tip thereof serves as the gas discharge port 30. In the present embodiment, the straight part 20 is inclined and arranged so as to be displaced downward as it reaches the reduced-diameter part 24, but the straight part 20 may be arranged horizontally. The end portion located on the side opposite to the curved part 22 of the straight part 20 is closed by an end face wall 26. Also, at a location of the straight part 20 near the end face wall 26, a gas introduction pipe 28 that protrudes downward in the radially outer direction from the straight part 20 and communicates with the inside of the outer cylinder part 12 is provided, and the lower end of the gas introduction pipe 28 serves as a gas introduction port 2802 into which exhaust gas (gas) is introduced. In the present embodiment, as shown in FIG. 4, the gas introduction port 2802 is connected to a waste treatment device 46 that incinerates or carbonizes by heating or pyrolyzing an object to be treated such as waste, and the exhaust gas generated by heating or pyrolyzing from the waste treatment device 46 is introduced as a gas.

[0010] In the present embodiment, by passing through the reduced-diameter part 24, the flow rate of the exhaust gas (gas) is increased, and it is intended that the discharge of the exhaust gas (gas) from the gas discharge port 30 is performed efficiently. Also, in the present embodiment, the gas discharge port 30 is open to the atmosphere, or is connected to another exhaust gas purification device that further purifies the gas (purified exhaust gas) discharged from the gas discharge port 30. Note that it is optional to provide a fan at the gas introduction port 2802 or the gas discharge port 30 to promote the introduction of the exhaust gas into the outer cylinder part 12.

[0011] In the present embodiment, at a location of the outer cylinder portion 12 near the gas discharge port 30, specifically, at the lower part of the curved portion 22, a liquid discharge pipe 32 communicating with the inside of the outer cylinder portion 12 protrudes downward. The lower end of the liquid discharge pipe 32 serves as a liquid discharge port 3202 that discharges water (liquid) flowing on the inner peripheral surface 2002 of the outer cylinder portion 12 (linear portion 20) to the outside of the outer cylinder portion 12. In the present embodiment, as shown in FIG. 4, the liquid discharge port 3202 communicates with the sewage treatment device 44 via a pipe 33. It is designed such that water (liquid) containing dust and the like discharged from the liquid discharge port 3202 has contaminants such as dust removed in the sewage treatment device 44 and is reused.

[0012] The rotating cylinder portion 14 extends along the linear portion 20 inside the linear portion 20 and is located coaxially with the linear portion 20. The rotating cylinder portion 14 is supported by the outer cylinder portion 12 so as to be rotatable about the central axis of the rotating cylinder portion 14. Specifically, a location near one end of the rotating cylinder portion 14 is supported by a bearing 34 provided on the end face wall 26, and one end of the rotating cylinder portion 14 penetrates the end face wall 26 and protrudes outside the linear portion 20. The other end of the rotating cylinder portion 14 is rotatably connected to the tip of the liquid supply pipe 38 via a swivel joint 36. Therefore, the rotating cylinder portion 14 is supported by the outer cylinder portion 12 so as to be rotatable via the bearing 34 and the swivel joint 36. The liquid supply pipe 38 extends outside the curved portion 22 through the wall portion of the curved portion 22 without rotating. A location near the tip of the liquid supply pipe 38 is supported by the linear portion 20 via a plurality of stays 40 and bearings 41 inside the linear portion 20. As shown in FIG. 4, the liquid supply pipe 38 is connected to the sewage treatment device 44 via a pump 42. The purified water stored in the sewage treatment device 44 is supplied to the inside of the rotating cylinder portion 14 via the liquid supply pipe 38 by the pump 42. In addition, in the present embodiment, the case where the swivel joint 36 is disposed inside the outer cylinder portion 12 has been described. However, it goes without saying that the other end of the rotary cylinder portion 14 may penetrate the wall portion of the outer cylinder portion 12 and be located outside, and the other end of the rotary cylinder portion 14 may be rotatably connected to the tip of the liquid supply pipe 38 via the swivel joint 36 outside the outer cylinder portion 12.

[0013] The plurality of injection nozzles 16 are provided at intervals along a counterclockwise spiral (left-handed spiral) locus on the outer peripheral surface 1402 of the rotary cylinder portion 14, and the injection ports 1602 of the plurality of injection nozzles 16 communicate with the inside of the rotary cylinder portion 14. Note that the counterclockwise spiral refers to a spiral that turns counterclockwise when tracing the spiral from the front to the back. In the present embodiment, as shown by the arrow F in FIG. 1, the exhaust gas (gas) flows from the gas inlet 2802 toward the gas outlet 30 inside the outer cylinder portion 12. As shown in FIG. 2, the axis of the injection port 1602 of the injection nozzle 16 is inclined toward the downstream side of the flow F of the exhaust gas (gas). Therefore, it is designed to be advantageous for smoothly guiding the exhaust gas (gas) from the gas inlet 2802 toward the gas outlet 30 by the water (liquid) injected from the injection nozzle 16. The inner diameter of the injection port 1602 is, for example, 0.5 mm.

[0014] The liquid supply unit 17 supplies liquid to the inside of the rotary cylinder portion 14 and injects water (liquid) from the plurality of injection nozzles 16. In the present embodiment, as shown in FIG. 4, the liquid supply unit 17 includes a sewage treatment device 44, a pump 42, and a liquid supply pipe 38.

[0015] As shown in FIG. 1, the rotation drive unit 18 rotates the rotary cylinder portion 14. In the present embodiment, the rotation drive unit 18 includes a motor 48, a first toothed pulley 50 provided on the drive shaft of the motor 48, a second toothed pulley 52 provided at the end of the rotary cylinder portion 14 protruding from the end face wall 26 of the outer cylinder portion 12, and a timing belt 54 wound around the first and second toothed pulleys 50 and 52. Specifically, the rotary drive unit 18 rotates the rotary cylinder unit 14 so that the gas is guided from the gas inlet 2802 to the gas outlet 30 by the liquid ejected from the plurality of injection nozzles 16. That is, since water (liquid) is ejected along the trajectory of a left-handed helix from the plurality of injection nozzles 16 provided at intervals along the trajectory of the left-handed helix, by rotating the rotary cylinder unit 14, the water (liquid) ejected along the trajectory of the helix also rotates following the rotation of the rotary cylinder unit 14, and the gas is guided along the longitudinal direction of the rotary cylinder unit 14 by the ejected water (liquid). In the present embodiment, the rotation direction of the rotary cylinder unit 14 is determined so that the gas is guided from the gas inlet 2802 to the gas outlet 30. Specifically, the rotation direction of the rotary cylinder unit 14 is determined to be a right rotation (clockwise rotation) when viewed from the side of the second toothed pulley 52.

[0016] Also, in the present embodiment, the rotation speed of the rotary cylinder unit 14 by the rotary drive unit 18 is, for example, 3 rotations per second. Note that the plurality of injection nozzles 16 may be provided at intervals along the trajectory of a right-handed helix (right helix). In that case, the rotation direction of the rotary cylinder unit 14 may be opposite to that of the embodiment.

[0017] As shown in FIG. 4, in the present embodiment, in the spiral type miniaturization device 10A, the exhaust gas discharged from the waste treatment device 46 is introduced into the outer cylinder unit 12 from the gas inlet 2802, and the introduced exhaust gas is mixed with the water ejected from the plurality of injection nozzles 16 and purified by contacting the water, and then discharged from the gas outlet 30. The water discharged from the liquid outlet 3202 is purified by the sewage purification device 44 and then introduced into the rotary cylinder unit 14 by the liquid supply unit 17.

[0018] Next, the operation and effects will be described. The rotary cylinder unit 14 is rotated in advance by the rotary drive unit 18, and water is supplied to the rotary cylinder unit 14 by the liquid supply unit 17 and ejected from the plurality of injection nozzles 16. At this time, the water jetted from the plurality of injection nozzles 16 collides with each other, or collides with the inner peripheral surface 2002 of the straight portion 20 (outer cylinder portion 12), and is refined into fine water particles. At this time, the refined fine water particles are negatively charged by the Lennard effect. On the other hand, since the exhaust gas discharged from the waste treatment device 46 is introduced into the inside of the outer cylinder portion 12 from the gas inlet 2802, it mixes with the negatively charged water particles. Here, since the particles of pollutants such as dust, sulfur oxides, and nitrogen oxides contained in the exhaust gas are positively charged, they are efficiently adsorbed by the negatively charged water particles, and these pollutant particles move downward in the vertical direction by the weight of the water particles together with the water particles and contact the inner peripheral surface 2002 of the straight portion 20 (outer cylinder portion 12). When a large number of water particles adsorbed with pollutant particles contact the inner peripheral surface 2002, they become liquid and can flow along the inner peripheral surface 2002, flow toward the liquid discharge port 3202 along the inclination of the outer cylinder portion 12, and are eventually discharged from the liquid discharge port 3202 and supplied to the sewage purification device 44 through the pipe 33. The water containing pollutant particles is purified by the sewage purification device 44 and supplied again from the liquid supply unit 17 to the rotating cylinder portion 14. Therefore, the water is reused as purified circulating water. Specifically, the sewage purification device 44 filters water containing pollutants such as dust with a filter to remove large particles of, for example, 50 μm or more among the pollutants such as dust, and generates purified circulating water. In addition, the exhaust gas is purified by the adsorption of the pollutant particles in the exhaust gas by the water particles, and the purified exhaust gas is discharged from the gas discharge port 30 and released into the atmosphere, or is further purified by another exhaust gas purification device and then released into the atmosphere.

[0019] Here, the phenomenon in which the exhaust gas is guided from the gas inlet 2802 to the gas discharge port 30 by the water (liquid) jetted from the plurality of injection nozzles 16, and the pollutant particles in the exhaust gas are adsorbed by the water particles will be described in detail. The water (liquid) injected from a plurality of injection nozzles inside the outer cylinder portion 12 forms a spiral of water. When this spiral of water is rotated (rotated clockwise when viewed from the side of the second toothed pulley 52), the spiral of water acts in the same way as an Archimedes screw (Archimedes' spiral). That is, as the spiral of water rotates, the exhaust gas (gas) is transferred from the gas inlet 2802 toward the gas outlet 30 by the propulsive force of the spiral of water. Here, since the particles of pollutants contained in the exhaust gas transferred by the spiral of water are transferred in close contact with the surface of the spiral of water, the particles of pollutants having the same size as the particles of water are adsorbed and captured by the particles of water. The particles of water that have captured the particles of pollutants become heavier and are thus repelled toward the inner peripheral surface 2002 of the outer cylinder portion by the centrifugal force of the spiral of water, come into contact with the inner peripheral surface 2002 and become liquid, and flow along the inner peripheral surface 2002. On the other hand, among the particles of pollutants in the exhaust gas, the particles of pollutants that have not been captured by the particles of water, or the particles of pollutants smaller than the particles of water, are sucked from the gas outlet 30, for example, by another exhaust gas purification device, purified, and then discharged into the atmosphere. In this case, as described above, if a fan is provided at the gas inlet 2802 so as to forcibly suck the exhaust gas into the outer cylinder portion 12, in addition to the propulsive force of the spiral of water, the suction force by the fan acts on the exhaust gas, and it is possible to ensure a large transfer amount and flow rate of the exhaust gas, which is advantageous for maximizing the adsorption and capture of the particles of pollutants in the exhaust gas by the particles of water.

[0020] According to the present embodiment, with a simple configuration such as rotating the rotating cylinder portion 14 provided with a plurality of injection nozzles 16 inside the outer cylinder portion 12, the exhaust gas (gas) introduced into the outer cylinder portion 12 is injected from the plurality of injection nozzles 16 and collides with each other, or collides with the inner peripheral surface 2002 of the outer cylinder portion 12 and is thus mixed with the particles of water (liquid) refined thereby, which is advantageous for efficiently mixing the exhaust gas (gas) and the particles of water (liquid). Therefore, it is advantageous in enhancing the purification efficiency of exhaust gas by adsorbing the pollutant particles contained in the exhaust gas onto the water particles and efficiently removing the pollutant particles from the exhaust gas. In addition, a plurality of injection nozzles 16 are provided at intervals along a spiral locus on the outer peripheral surface 1402 of the rotary cylinder portion 14, and the rotary cylinder portion 14 is rotated so that the exhaust gas (gas) is guided from the gas inlet 2802 to the gas outlet 30 by the water (liquid) injected from the plurality of injection nozzles 16. Therefore, the exhaust gas can be efficiently guided from the gas inlet 2802 to the gas outlet 30 by the water injected from the plurality of injection nozzles 16, which is advantageous in enhancing the purification efficiency of the exhaust gas.

[0021] Further, in the present embodiment, since the axis of the injection port 1602 of the injection nozzle 16 is inclined toward the downstream side of the flow F of the exhaust gas, it is more advantageous in efficiently guiding the exhaust gas from the gas inlet 2802 to the gas outlet 30 by the water injected from the plurality of injection nozzles 16, and is more advantageous in enhancing the purification efficiency of the exhaust gas.

[0022] Moreover, in the present embodiment, the exhaust gas introduced into the outer cylinder portion 12 from the gas inlet 2802 is purified by the water injected from the injection nozzles 16 and discharged from the gas outlet 30, and after the water discharged from the liquid outlet 3202 is purified, it is introduced into the liquid supply unit 17. Therefore, by reusing the water, the amount of water used can be suppressed, which is advantageous in reducing the operation cost.

[0023] FIG. 3 is a diagram showing the test results when the exhaust gas is treated using the spiral type miniaturization device 10A of the first embodiment. The test contents are as follows. 10 kg of coal was burned for 1 hour, and the generated exhaust gas was supplied to the spiral type miniaturization device 10A for 4 hours to treat the exhaust gas. Then, at two locations, namely the gas inlet 2802 and the gas outlet 30, the dust concentration, sulfur oxide concentration, nitrogen oxide concentration, and average oxygen concentration were measured respectively, and the average value per hour of these measured values was obtained. At this time, the flow velocity of the exhaust gas (gas) at the gas outlet 30 was 4.1 m / s. When comparing the measured values at the gas inlet 2802 with those at the gas outlet 30, it became clear that the removal of pollutant particles contained in the exhaust gas was being carried out efficiently.

[0024] (Second Embodiment) Next, the second embodiment will be described with reference to FIGS. 1 and 5. In the following embodiments, the same parts and members as those in the first embodiment are denoted by the same reference numerals as in the first embodiment, and the description thereof is omitted, and the different parts will be mainly described. The second embodiment will be described in the case where the spiral type miniaturization device 10B is configured as an ethanol gas generation device that generates air containing ethanol by mixing ethanol as a liquid with air as a gas. The configuration of the spiral type miniaturization device 10B is the same as that in the first embodiment as shown in FIG. 1. In the second embodiment, the gas inlet 2802 is open to the atmosphere. Also, as shown in FIG. 5, ethanol is supplied from the ethanol tank 56 storing ethanol to the rotating cylinder portion 14 via the pump 42 and the liquid supply pipe 38, and the remaining ethanol that has not been mixed with air is recovered from the liquid outlet 3202 to the ethanol tank 56 via the pipe 33. The air (ethanol gas) in which ethanol is mixed inside the outer cylinder portion 12 is supplied from the gas outlet 30 to the thermal power generation device 58. In the second embodiment, the liquid supply unit 17 is configured to include an ethanol tank 56, a pump 42, and a liquid supply pipe 38. In the second embodiment, the inner diameter of the injection port 1602 is, for example, 0.5 mm, and the rotational speed of the rotating cylinder portion 14 by the rotational drive unit 18 is, for example, 6 rotations per second.

[0025] The operation and effects will be described. In advance, the rotary cylinder portion 14 is rotated by the rotary drive portion 18, and ethanol is supplied to the rotary cylinder portion 14 by the liquid supply portion 17 and is ejected from the plurality of injection nozzles 16. At this time, the ethanol ejected from the plurality of injection nozzles 16 collides with each other, or collides with the inner peripheral surface 2002 of the straight portion 20 (outer cylinder portion 12) to be refined into fine ethanol particles. On the other hand, since the air introduced from the atmosphere is introduced into the outer cylinder portion 12 from the gas inlet 2802, it mixes with the ethanol particles to generate ethanol gas. A part of the ethanol particles moves downward in the vertical direction due to its own weight and contacts the inner peripheral surface 2002 of the straight portion 20 (outer cylinder portion 12). A large number of ethanol particles become liquid by contacting the inner peripheral surface 2002 and become in a state where they can flow along the inner peripheral surface 2002, flow toward the liquid discharge port 3202 along the inclination of the outer cylinder portion 12, and are eventually discharged from the liquid discharge port 3202 and recovered into the ethanol tank 56 via the pipe 33. The ethanol recovered in the ethanol tank 56 is supplied again from the liquid supply portion 17 to the rotary cylinder portion 14. In addition, the air mixed with the ethanol particles is discharged as ethanol gas from the gas discharge port 30 and supplied to the thermal power generation device 58, burned by the thermal power generation device 58, and power is generated by the thermal power generation device 58.

[0026] According to the present embodiment, with a simple configuration such as rotating the rotary cylinder portion 14 provided with a plurality of injection nozzles 16 inside the outer cylinder portion 12, the air (gas) introduced into the outer cylinder portion 12 is ejected from the plurality of injection nozzles 16 and collides with each other, or collides with the inner peripheral surface 2002 of the outer cylinder portion 12 to be mixed with the refined ethanol (liquid) particles. Therefore, it is advantageous for efficiently mixing the air (gas) and the ethanol (liquid) particles. Therefore, it is advantageous for efficiently generating ethanol gas in which ethanol particles are mixed with air. In addition, a plurality of injection nozzles 16 are provided at intervals along a spiral locus on the outer peripheral surface 1402 of the rotating cylinder portion 14, and the rotating cylinder portion 14 is rotated so that air (gas) is guided from the gas inlet 2802 to the gas outlet 30 by ethanol (liquid) injected from the plurality of injection nozzles 16. Therefore, air mixed with ethanol particles can be efficiently guided from the gas inlet 2802 to the gas outlet 30 by the ethanol injected from the plurality of injection nozzles 16, which is advantageous for efficiently supplying ethanol gas to the thermal power generation device 58.

[0027] In addition, in the present embodiment, since the axis of the injection port 1602 of the injection nozzle 16 is inclined toward the downstream side of the gas flow, it is more advantageous for efficiently guiding air from the gas inlet 2802 to the gas outlet 30 by the ethanol injected from the plurality of injection nozzles 16, and it is more advantageous for efficiently supplying ethanol gas to the thermal power generation device 58.

[0028] In addition, in the present embodiment, air containing ethanol injected from the injection nozzle 16 is discharged as ethanol gas from the gas outlet 30, and after the ethanol discharged from the liquid outlet 3202 is recovered, it is introduced into the liquid supply unit 17. Therefore, the amount of ethanol used can be suppressed by using ethanol without waste, which is advantageous for reducing the operation cost.

[0029] In the embodiment, the case where the gas is exhaust gas or air and the liquid is water or ethanol has been described. However, as long as the liquid can be atomized and mixed with the gas, various conventionally known gases and liquids can be used for the liquid and the gas.

[0030] In the embodiment, the rotating tube portion 14 of one spiral type miniaturization device 10A or 10B is rotated by the rotational force of one motor 48. However, for example, two or more spiral type miniaturization devices may be arranged at intervals on the same circumference, and the rotating tube portions 14 of these multiple spiral type miniaturization devices may be rotated by one motor 48. In this case, while simplifying the configuration of the rotation drive unit 18, it is advantageous for efficiently mixing a large amount of gas and liquid particles.
