  According to this configuration, the gap between the introduction nozzle and the straight tube portion can be obtained by alternatively attaching a plurality of types of introduction nozzles that can be attached to and removed from the proximal end tube portion of the cheese tube to the base end tube portion. The length and / or cross-sectional area can be varied. Thus, raw water that flows from the cross pipe to the tip pipe and sucks and mixes the electrolytic product from the inner hole of the introduction nozzle flows through the gap between the introduction nozzle and the straight pipe. Flow rate can be changed. Therefore, the flow rate of the raw water can be easily changed.

  The tip end portion of the inner hole of the introduction nozzle may be formed in a tapered shape which increases in diameter toward the tip end. According to this structure, the electrolytic product can be efficiently sucked.

  A plurality of introduction ports of the electrolytic product connected to the inner hole may be formed in the introduction nozzle. According to this structure, the number of connected electrolytic cells can be increased or decreased to increase or decrease the supply amount of the electrolytic product.

  The proximal end portion of the introduction nozzle may be provided with an abutment portion which abuts on the proximal end tube portion to define an insertion length of the introduction nozzle into the straight tube portion. According to this structure, when the introduction nozzle is attached to the cheese pipe, the insertion length of the introduction nozzle into the straight pipe portion can be defined by bringing the contact portion into contact with the proximal end pipe portion. Thus, the inlet nozzle can be easily positioned relative to the cheese tube.

  Electrolyzed products may be mixed with raw water to produce electrolyzed water. In this case, an electrolysis water is mixed with raw water to form an electrolyzed water.

  The electrolytic product may be mixed with the raw water to sterilize or deodorize the raw water. In this case, an electrolysis product is mixed with the raw water to constitute a sterilizing apparatus for sterilizing or deodorizing the raw water.

Raw water may be tap water, sewage or drainage. Generally, in the case of treating these tap water, sewage and waste water, it is difficult to remove pathogens, viruses and further offensive odors with a filter alone. However, mixing the electrolytic products can solve this problem.
Also, the raw water may be ballast water for ships. In this case, a ballast water treatment apparatus will be configured which mixes the electrolytic product with the ballast water to sterilize the ballast water.
The ballast water treatment apparatus for ships according to the present invention comprises a ballast water tank for storing seawater as the ballast water, a pump for pumping the seawater to the ballast water tank, and all or one of the seawater pumped by the pump. And the above-mentioned electrolysis product mixing device introduced into the cross pipe portion of the suction and mixing device to make the raw water. Such a ballast water treatment system is preferably provided on a ship.
As the ballast water treatment capacity is required to have a wide lineup from hundreds of tons to tens of thousands of tons per hour according to the loading capacity of the ship, the flow rate can be changed simply by changing the diameter of the inlet nozzle Can be done easily.

Thus, raw water that flows from the cross pipe to the tip pipe and sucks and mixes the electrolytic product from the inner hole of the introduction nozzle flows through the gap between the introduction nozzle and the straight pipe. Flow rate can be changed. Therefore, the flow rate of the raw water can be easily changed.
The principle of the present invention is the same as an orifice flow meter (differential pressure flow meter), and when the flow is squeezed in the middle of the pipe, the pressure of the fluid decreases. Since this change relates to the fluid density and the flow velocity, measuring the pressure difference between the upstream side and the downstream side reveals the flow rate. This flow rate is a volumetric flow rate, and can be measured from a small flow rate to a large flow rate. Commercially available general flowmeters require a flow of fluid before shipment and require calibration to check the relationship between flow rate and output. However, differential pressure flowmeters are manufactured and installed according to the specific throttle structure and pipe diameter range. Then, no real flow calibration is necessary. For measuring instruments that require calibration, such as flowmeters, when the flow rate increases, initial costs and maintenance costs increase. However, in the present invention, the flow rate is guaranteed with the accuracy of dimensional inspection in the diameter of the barrel of the introduction nozzle, which is very advantageous in cost.

  According to this configuration, the gap between the introduction nozzle and the straight tube portion can be obtained by alternatively attaching a plurality of types of introduction nozzles that can be attached to and removed from the proximal end tube portion of the cheese tube to the base end tube portion. Change at least one of the length and the cross-sectional area. Thus, raw water that flows from the cross pipe to the tip pipe and sucks and mixes the electrolytic product from the inner hole of the introduction nozzle flows through the gap between the introduction nozzle and the straight pipe.

  Hereinafter, an electrolysis product mixing device of one embodiment concerning the present invention is explained with reference to drawings.

  As shown in FIG. 1, the electrolytic product mixing apparatus 11 according to the embodiment includes an electrolytic solution tank 12 for storing an electrolytic solution, an electrolytic solution pump 13 for suctioning and discharging an electrolytic solution from the electrolytic solution tank 12, and an electrolytic solution pump An electrolysis module 16 having an electrolytic cell 14 into which the electrolytic solution discharged from 13 is introduced and an electrolytic power source 15 for supplying electric power to the electrolytic cell 14 is provided. The electrolytic cell 14 electrolyzes the electrolytic solution with the power supplied from the electrolytic power source 15. In addition, the electrolysis product mixing device 11 sucks and mixes the electrolysis product generated by the electrolytic cell 14 with the flow of the introduced raw water and mixes it with the raw water and leads out by the flow of the introduced raw water. A device 21 is provided.

  The electrolytic cell 14 electrolyzes the introduced electrolytic solution to produce an electrolytic product. Here, for example, the electrolytic solution contains chlorine ions such as an aqueous solution of sodium chloride and an aqueous solution of hydrochloric acid, and the electrolytic cell 14 generates chlorine gas as an electrolytic product by the action of electrolytic oxidation. Raw water is introduced into the suction and mixing apparatus 21 and chlorine gas, which is an electrolysis product, is sucked by the flow of the introduced raw water and mixed with the raw water. A well-known thing can be used suitably for the electrolytic vessel 14. Hereinafter, a case where the electrolytic cell 14 generates chlorine gas as an electrolysis product as described above will be described as an example.

  As shown in FIG. 2, the suction and mixing device 21 has a cylindrical intersection which linearly extends in a cylindrical straight pipe portion 22, and which extends linearly and intersects a peripheral wall at an intermediate position in the axial direction of the straight pipe portion 22. A T-shaped cheese tube 24 (Tee, Tees) having a tube portion 23, an introduction nozzle 25 detachably provided to the cheese tube 24, and an attachment nozzle 25 for attaching or detaching the cheese tube 24 And a union nut 26.

  The cross pipe portion 23 is perpendicular to the central axis of the straight pipe portion 22, and protrudes outward in the radial direction from the peripheral wall of the straight pipe portion 22. The cross pipe portion 23 has an inner hole 31 of a fixed diameter. In the cross pipe portion 23, the inlet 32 opposite to the straight pipe portion 22 is in communication with the raw water supply source. That is, raw water will be introduced into the cross pipe portion 23 from the inlet 32 in the cheese pipe 24, and the straight pipe portion 22 is disposed downstream of the cross pipe portion 23 in the flow direction of the raw water .

  The straight pipe portion 22 is a cylindrical surface having a constant diameter regardless of the axial position, except for the inner opening 33 which is an opening to the straight pipe portion 22 of the cross pipe portion 23. That is, the straight pipe portion 22 has an inner hole 42 of a fixed diameter.

  The straight pipe portion 22 is a proximal end pipe portion 43 to which the introduction nozzle 25 is connected and closed to form a proximal end pipe portion 43 at a portion closer to the axial direction than the cross pipe portion 23. A portion opposite to the end pipe portion 43 is a tip end pipe portion 44. The tip end portion 45 opposite to the axial cross section 23 is connected to the supply destination of the raw water after the chlorine gas mixture. That is, the tip end pipe portion 44 is disposed on the downstream side of the intersecting pipe portion 23 in the direction of the flow of the raw water. In other words, in the cheese tube 24, the cross pipe portion 23 is upstream of the tip pipe portion 44 in the flow direction of the raw water, and the tip pipe portion 44 is downstream of the cross pipe portion 23 in the flow direction of the raw water . Therefore, raw water flows from the cross pipe portion 23 toward the tip pipe portion 44 in the cheese pipe 24, and after the chlorine gas is mixed in the raw water (described later), the raw water flows from the tip end 45 of the tip pipe portion 44 It is discharged to the supply destination.

  The proximal end pipe portion 43 is formed with an annular flange portion 48 projecting radially outward at an end portion. The union nut 26 has a cylindrical shape, and an annular inner flange portion 51 projecting radially inward is formed at one end in the axial direction, and a female screw 52 is formed on the inner peripheral side on the other side in the axial direction. The union nut 26 is held by the cheese tube 24 so that the inner flange portion 51 can be moved between the flange portion 48 as the union flange of the base end pipe portion 43 and the cross pipe portion 23, When the portion 51 abuts on the flange portion 48 of the proximal end pipe portion 43, the movement in the direction away from the cross pipe portion 23 is further restricted. When the inner flange portion 51 abuts on the flange portion 48 as described above, the female screw 52 of the union nut 26 is disposed axially outside the proximal end pipe portion 43.

  The introduction nozzle 25 is inserted into the straight pipe portion 22 of the cheese pipe 24 from the proximal end pipe portion 43 and mounted on the proximal end pipe portion 43. The introduction nozzle 25 can be repeatedly attached to and removed from the proximal end tube portion 43, that is, can be detachably attached. The introduction nozzle 25 is fixed by being fitted to the inside of the union bolt 62 and the union bolt 62 of the base end formed on the outer peripheral portion on one axial side with the male screw 61 screwed with the female screw 52 of the union nut 26 Connection with one end side attached to the cylindrical base 63 at the base end, the nozzle main body 64 extending from the base 63 into the straight pipe portion 22 of the cheese tube 24, and the straight pipe portion 22 of the base 63 And a tubular body 65. The other end side of the connection pipe 65 is in communication with the electrolytic cell 14 shown in FIG.

  As shown in FIG. 2, the union bolt 62 has a cylindrical shape, and has a fitting hole 71 formed on the inner side from the end opposite to the axial male screw 61 to the middle part, and the axial direction And an inner hole 72 formed at the end on the male screw 61 side. The inner hole 72 has a diameter smaller than that of the fitting hole 71. Therefore, an annular inner flange portion 73 projecting radially inward is formed on the end of the union bolt 62 on the side of the male screw 61 in the axial direction. It is done. The base 63 is fitted and fixed in the fitting hole 71 of the union bolt 62 and abuts on the inner flange portion 73. In this state, the gap with the union bolt 62 is sealed. An annular recess 77 axially recessed from the end surface 76 is formed in the end surface 76 of the union bolt 62 on the side of the male screw 61 in the axial direction. An O-ring 78 is disposed in the recess 77.

  After the nozzle body 64 is inserted from the proximal end pipe portion 43 into the inner hole 42 of the straight pipe portion 22 of the cheese tube 24 with the O-ring 78 disposed in the recess 77 of the union bolt 62, The end face 76 on the concave portion 77 side of the union bolt 62 is brought into contact with the end face 81 on the flange portion 48 side of the base end pipe portion 43 of the cheese tube 24. In this state, by screwing the female screw 52 of the union nut 26 to the male screw 61 of the union bolt 62 and tightening the union nut 26, the inner flange portion 51 of the union nut 26 engages the flange portion 48 of the base end pipe portion 43. Press on the union bolt 62. At that time, the O-ring 78 of the concave portion 77 of the union bolt 62 abuts on the end surface 81 of the proximal end tube portion 43 and is elastically deformed. Thus, the O-ring 78 seals the gap between the union bolt 62 and the proximal end tube portion 43. Thus, the introduction nozzle 25 is attached to the proximal end 43 of the cheese tube 24. From this state, when the screwing of the female screw 52 of the union nut 26 to the male screw 61 of the union nut 26 is loosened and released, the connection of the introduction nozzle 25 to the proximal end tube portion 43 of the cheese tube 24 is released. , Proximal end tube portion 43.

  The introduction nozzle 25 is disposed outside the straight pipe portion 22 without the union bolt 62 and the base 63 at the base end thereof being inserted into the inner hole of the straight pipe portion 22 and attached to the cheese pipe 24 by the union nut 26 The mounting portion 85 is formed. Further, the flange portion 48 of the proximal end tube portion 43, the union nut 26, and the union bolt 62 form a detachable connection portion 86 for detachably connecting the attachment portion 85 of the introduction nozzle 25 to the proximal end tube portion 43. There is. That is, the detachable connection part 86 is a union joint (universal union). The inner circumferential surface 88 of the inner flange portion 73 of the union bolt 62 has the same diameter as the inner circumferential surface 41 of the straight tube portion 22 of the cheese tube 24, and the introduction nozzle 25 is attached to the cheese tube 24, The inner circumferential surface 41 of the straight pipe portion 22 and the central axis line are made to coincide with each other and continue.

  An end on the male screw 61 side in the axial direction of the union bolt 62 is an abutting portion 91 that abuts on the end surface 81 on the flange portion 48 side in the axial direction of the proximal end pipe portion 43 at the end surface 76 thereof. When the male screw 61 of the introduction nozzle 25 is screwed into the female screw 52 of the union nut 26 and tightened, the contact portion 91 abuts on the axial end of the proximal end tube portion 43. In this state, the abutment portion 91 of the union bolt 62 at the proximal end of the introduction nozzle 25 abuts on the proximal end pipe portion 43 to define the insertion length of the introduction nozzle 25 into the straight pipe portion 22. In other words, the projection length of the nozzle body 64 from the abutment portion 91 is predetermined, and when the abutment portion 91 abuts on the proximal end tube portion 43, the tip end surface 94 of the nozzle body 64 of this predetermined length is straight It is axially positioned relative to the tube 22. The insertion length of the introduction nozzle 25 is such that the nozzle body 64 traverses the inner opening 33 of the cross pipe portion 23 in the axial direction of the straight pipe portion 22 and the tip opening 45 of the tip pipe portion 44 and the inside of the cross pipe portion 23 The end surface 94 is positioned between the opening 33 and the opening 33.

  The introduction nozzle 25 has an inner hole 95 on the central axis, and the nozzle body 64 is formed in a cylindrical shape in which the inner hole 95 penetrates in the axial direction. The outer peripheral surface 96 of the nozzle main body 64 is a cylindrical surface having a constant diameter regardless of the axial position. The nozzle main body 64 is disposed on the inner side of the straight pipe portion 22 with the center axis aligned with the straight pipe portion 22 in a state where the mounting portion 85 is mounted to the proximal end pipe portion 43 of the cheese pipe 24 by the union nut 26. It will be. Therefore, the straight pipe portion 22 of the cheese pipe 24 is an outer cylindrical pipe disposed outside so as to cover the nozzle main body 64 of the introduction nozzle 25, and the nozzle main body 64 is disposed inside the straight pipe portion 22 It is a tube.

  With the mounting portion 85 attached to the proximal end pipe portion 43, the inner peripheral surface 41 of the straight pipe portion 22 and the inner peripheral surface 88 of the inner flange portion 73 of the union bolt 62 and the outer peripheral surface 96 of the nozzle body 64 A gap 101 is formed between the two. In other words, the introduction nozzle 25 forms a gap 101 between the straight pipe portion 22 and the inner flange portion 73 of the union bolt 62 in a state of being attached to the straight pipe portion 22 of the cheese pipe 24. The gap 101 has a cylindrical shape, one end of which is closed by the base 63, and the opening 102 at the other end is a tip end portion 45 of the nozzle main body 64 in the straight pipe portion 22 at the tip end position of the nozzle main body 64. It is open to the side. The gap 101 has the same length as the projection length of the nozzle main body 64 from the base 63, and has a length that traverses the inner opening 33 of the cross pipe portion 23 in the axial direction of the straight pipe portion 22. The raw water introduced into the cross pipe portion 23 flows in the gap 101 and reaches from the opening 102 of the gap 101 to a range where the nozzle main body 64 in the tip pipe portion 44 is absent, and from the tip end 45 toward the supply destination Flow.

  The inner hole 95 of the introduction nozzle 25 is in communication with the inside of the connection pipe 65, and thus causes the chlorine gas generated in the electrolytic cell 14 shown in FIG. 1 to flow. As shown in FIG. 3, the inner hole 95 of the introduction nozzle 25 has a tapered hole portion 105 having a tapered shape which is expanded toward the tip end surface 94 at the tip end portion. On the end side, a cylindrical hole portion 106 having a constant diameter is provided regardless of the axial position. The end of the tapered hole 105 opposite to the cylindrical hole 106 is the opening 107 of the inner hole 95.

  In the suction / mixing apparatus 21 shown in FIG. 2, the pressurized raw water is introduced into the cross pipe portion 23 of the cheese pipe 24, passes through the gap 101 between the nozzle main body 64 and the straight pipe portion 22, and the straight pipe portion It reaches the tip pipe portion 44 of 22 and flows toward the supply destination. At that time, the flow of the raw water generates a negative pressure in the vicinity of the opening 107 of the inner hole 95 of the introduction nozzle 25 by the principle of the ejector, and chlorine gas which is an electrolysis product is sucked from the electrolytic cell 14 through the inner hole 95 Do. Thus, chlorine gas is introduced from the inner hole 95 into the raw water at the mixing portion 111 near the opening 107 in the inner hole 42 of the straight pipe portion 22 and mixed. Thus, raw water mixed with chlorine gas flows toward the supply destination. That is, the suction mixing device 21 is an ejector that sucks chlorine gas, which is a gas, using raw water, which is a liquid, as a driving fluid.

  Here, specific examples of dimensions of portions related to the flow of raw water and chlorine gas of the suction and mixing device 21 will be described. For example, the inner diameter of the inner hole 42 of the straight pipe portion 22 is φ30 mm, the outer diameter of the nozzle main body 64 is φ29 mm, and the inner diameter of the cylindrical hole portion 106 of the inner hole 95 of the introduction nozzle 25 shown in FIG. The angle of the tapered hole portion 105 (the angle formed by the two lines appearing when the tapered hole portion 105 is a cross section in a plane including the central axis) is 25 mm in depth from the tip end surface 94 of the nozzle body 64 of the portion 105 It is 40 degrees. In this case, a gap 101 between the straight pipe portion 22 and the nozzle main body 64 shown in FIG. 2 has a dimension of 0.5 mm on a radial line extending from the central axis to one side in the radial direction.

  The electrolytic product mixing device 11 is provided with a plurality of types of introduction nozzles 25 having different nozzle bodies 64, specifically, four types as shown in FIG. In the following description, when it is necessary to distinguish these, they are distinguished as the introduction nozzle 25 (A), the introduction nozzle 25 (B), the introduction nozzle 25 (C), and the introduction nozzle 25 (D). Then, the parts related to each of them are similarly distinguished by adding (A), (B), (C), (D) to the reference numerals.

And a nozzle 25 (D). The nozzle body 64 (D) has the same length as the nozzle body 64 (C), and has the same size as the nozzle body 64 (B). That is, among the nozzle bodies 64 (A) to 64 (D), the nozzle body 64 (A) is short and thin, the nozzle body 64 (B) is short and thick, and the nozzle body 64 (C) is long and thin, The nozzle body 64 (D) is long and thick.

  Here, in these introduction nozzles 25 (A) to 25 (D), the attachment portion 85 and the union nut 26 have a common shape, and therefore both can be attached to the same proximal tube portion 43 by the union nut 26. However, it is detachable. In other words, the introduction nozzles 25 (A) to 25 (D) are all detachably attachable to the proximal end tube portion 43 of the same cheese tube 24 and are alternatively selected to be the same cheese tube 24 Attached to the proximal tube portion 43 of the In other words, the detachable connecting portion 86 for detachably connecting the attaching portion 85 of only one introducing nozzle 25 to the proximal end pipe portion 43 is common to these introducing nozzles 25 (A) to 25 (D). The shape is such that all of the introduction nozzles 25 (A) to 25 (D) can be connected to the proximal tube portion 43. That is, the introduction nozzles 25 (A) to 25 (D) can be replaced and attached to the proximal end tube portion 43 of the same cheese tube 24.

  When these introduction nozzles 25 (A) to 25 (D) are alternatively attached to the proximal end pipe portion 43 of the cheese tube 24, compared with the case where the other introduction nozzles 25 are attached, the straight pipe portion 22 and At least one of the length and the cross-sectional area of the gap 101 between them is changed. That is, as shown in FIG. 5A, the gap when the introduction nozzle 25 (A) is selected from these introduction nozzles 25 (A) to 25 (D) and attached to the proximal end tube portion 43 Based on the length and cross-sectional area of 101 (A), the introduction nozzle 25 has a nozzle body 64 (B) shown in FIG. 5 (b) which is the same in length and thicker than the nozzle body 64 (A). When (B) is selected and attached to the proximal tube portion 43, the gap 101 (B) has the same length as the gap 101 (A) and a smaller cross-sectional area. Further, the introduction nozzle 25 (C) having the nozzle main body 64 (C) shown in FIG. 5 (c) having a longer length and the same thickness as the nozzle main body 64 (A) is selected and attached to the proximal end pipe portion 43 Then, the gap 101 (C) has the same cross-sectional area as the gap 101 (A) and has a long length. Further, the introduction nozzle 25 (D) having the nozzle main body 64 (D) shown in FIG. 5 (d), which is longer and thicker than the nozzle main body 64 (A), is selected and attached to the proximal end tube portion 43 Then, the gap 101 (D) has a smaller cross-sectional area than the gap 101 (A) and a longer length.

  In other words, the electrolytic product mixing device 11 has a plurality of types of introduction nozzles whose suction mixing device 21 can change at least one of the length and the cross-sectional area of the gap 101 with the straight pipe portion 22. 25 (A) to 25 (D), and these introduction nozzles 25 (A) to 25 (D) are alternatively attached to the proximal tube portion 43. In other words, in the electrolytic product mixing method of mixing chlorine gas into raw water using this electrolytic product mixing device 11, a plurality of types of introduction nozzles 25 (A) to 25 (D) are prepared, and these introduction nozzles 25 are prepared. By selectively attaching (A) to 25 (D) to the proximal end pipe portion 43, the length of the gap 101 between the introduction nozzle 25 attached to the proximal end pipe portion 43 and the straight pipe portion 22, and Change at least one of the cross-sectional areas.

  According to the embodiment described above, the introduction nozzle 25 and the plurality of types of introduction nozzles 25 which can be attached to and detached from the proximal end pipe portion 43 of the cheese tube 24 are alternatively attached to the proximal end pipe portion 43. At least one of the length and the cross-sectional area of the gap 101 between the straight pipe portion 22 can be changed. Therefore, raw water that flows from the cross pipe 23 toward the tip pipe 44 from the cross pipe 23 and sucks and mixes chlorine gas from the inner hole 95 of the introduction nozzle 25 is between the introduction nozzle 25 and the straight pipe 22. The flow rate as it flows through the gap 101 can be changed. Therefore, the flow rate of the raw water can be easily changed.

  Specifically, as shown in FIG. 5 (a), when the introduction nozzle 25 (A) having the nozzle main body 64 (A) is selected and attached to the proximal end tube portion 43, four introduction nozzles are provided. Among the cases where each of 25 (A) to 25 (D) is attached, the raw water flow rate is the largest. Based on this flow rate, the introduction nozzle 25 (B) having the nozzle main body 64 (B) shown in FIG. 5 (b) has the same length and thickness as the nozzle main body 64 (A). When attached to 43, the gap 101 (B) has the same cross-sectional area as the gap 101 (A) but has the same length, so the flow rate of the raw water decreases. Further, when the introduction nozzle 25 (C) having the nozzle main body 64 (C) shown in FIG. 5 (c), which has a longer length and the same thickness as the nozzle main body 64 (A), is attached to the proximal end tube portion 43, Since the gap 101 (C) has the same cross-sectional length as the gap 101 (A), the pressure loss reduces the flow rate of the raw water. Further, when the introduction nozzle 25 (D) having the nozzle main body 64 (D) shown in FIG. 5 (d) having a long length and a large thickness with respect to the nozzle main body 64 (A) is attached to the proximal end tube portion 43, The gap 101 (D) has a smaller cross-sectional area and a longer length than the gap 101 (A), so that the flow rate of the raw water is reduced. When the introduction nozzles 25 (D) are attached, the flow rate of the raw water is reduced most among the cases where each of the four introduction nozzles 25 (A) to 25 (D) is attached.

  Here, if the flow rate of the raw water increases when the chlorine gas generation amount by the electrolytic cell 14 is constant, the chlorine concentration of the raw water after mixing decreases, and if the flow rate of the raw water increases, the chlorine concentration of the raw water after mixing Get higher. In addition, by controlling the amount of chlorine gas generated by the electrolytic cell 14, the flow rate of the raw water after mixing can be increased or decreased while maintaining the chlorine concentration constant.

  So far in the electrolyzed water production apparatus as an example of the electrolyzed product mixing apparatus, the scale of the equipment has been almost fixed due to the capacity of the apparatus. Therefore, once the equipment was completed, changing the manufacturing capacity required a great deal of expense and effort. In addition, large-scale equipment and equipment are relatively easy to introduce at the time of new construction, but often difficult to incorporate into existing equipment. Usually, the flow rate, electrolytic capacity, and size of the electrolytic cell of the electrolyzed water production apparatus are determined for each type of production apparatus, and a plurality of product specifications are prepared by the manufacturer. Customers will choose the one that best suits them. At that time, over specs or lack of ability may occur. Moreover, not only the problem of the capacity but also the arrangement of the piping, the size of the device, the shape, etc. have disadvantages such as not being included in the existing equipment. In the past, there was one model for one capability, and to change the capability, it was necessary to replace the device body, that is, to prepare another commodity or a plurality of devices. On the other hand, the electrolytic product mixing apparatus 11 of the present embodiment can change the capacity only by replacing the suction and mixing apparatus 21 with respect to the existing electrolytic product mixing apparatus having a different structure from this. Ability can be changed at low cost.

  Further, in consideration of cost reduction of the apparatus, the number of product items should be as small as possible in consideration of commonality of parts. However, in order to meet the needs of customers, it is necessary to prepare a large number of items, which is costly. Furthermore, there was also a problem that the stock as a product had to be held to some extent. On the other hand, in the electrolysis product mixing device 11 of the present embodiment, the capacity can be changed only by replacing the introduction nozzle 25 and other parts can be made common, so even if the number of product items is large, it is substantial It is possible to cope with this by increasing the number of items of the introduction nozzle 25 and to reduce the total amount of stock.

  Further, since the introduction nozzle 25 is detachable, inspection and maintenance of the introduction nozzle 25 can be easily performed.

  Further, since the tip end portion of the inner hole 95 of the introduction nozzle 25 is formed in a tapered shape which is expanded in diameter toward the tip end, chlorine gas which is an electrolytic product can be efficiently sucked.

  In addition, since the abutment portion 91 which abuts on the proximal end pipe portion 43 and defines the insertion length of the introduction nozzle 25 into the straight pipe portion 22 is provided at the proximal end portion of the introduction nozzle 25, the introduction nozzle If the contact portion 91 is brought into contact with the proximal end pipe portion 43 when attaching the cheese tube 25 to the cheese pipe 24, the insertion length of the introduction nozzle 25 into the straight pipe portion 22 can be defined. Therefore, the inlet nozzle 25 can be easily positioned with respect to the cheese tube 24. Therefore, the mixing of chlorine gas into the raw water can be made appropriate and constant.

  Here, all of the plurality of types of introduction nozzles 25 can be connected, and the mounting portion 85 of only one of the plurality of types of introduction nozzles 25 is detachably connected to the proximal end pipe portion 43 of the cheese tube 24 As the detachable connection part 86, it is also possible to employ other than the detachable connection part 86 of the above-mentioned union joint structure.

  For example, as shown in FIG. 6, the union nut 26 shown in FIG. 2 is eliminated and the mounting member 121 is fixed to the base 63 (not shown in FIG. 6) in place of the union bolt 62. An annular flange portion 122 projecting radially outward is provided at an end portion of the mounting member 121 opposite to the connection pipe 65. Then, the flange portion 48 of the proximal end tube portion 43 and the flange portion 122 are brought into contact with each other, and the flange portions 48 and 122 are held by the clip member 123. The clip member 123 is formed by bending a strip-like plate material, and is elastically deformable. A fitting groove 124 is formed in the clip member 123, and the flange portions 48 and 122 are held by arranging the flange portions 48 and 122 in the fitting groove 124 at the same time. In this case, the flanges 48 and 122 and the clip member 123 can connect all of the plurality of types of introduction nozzles 25, and only one of the plurality of types of introduction nozzles 25 is attached to and removed from the proximal end pipe portion 43. Thus, the distal end of the flange portion 122 of the mounting member 121 abuts on the proximal end pipe portion 43 and the introduction nozzle 25 into the straight pipe portion 22 (in FIG. 6). It becomes the contact part 126 which defines the insertion length of (not shown).

  Further, for example, as shown in FIG. 7, the union nut 26 shown in FIG. 2 is eliminated and the mounting bolt 131 in the form of a perforated disk is fixed to the base 63 instead of the union bolt 62. Further, the outer diameter of the flange portion 48 of the proximal end tube portion 43 is made larger according to the mounting member 131. Then, in a state where the perforated disk-like packing 132 is held between the mounting member 131 and the flange portion 48, the mounting member 131 and the flange portion 48 are fastened by a plurality of fasteners 135 including the bolt 133 and the nut 134. In this case, the mounting member 131, the flange portion 48, the packing 132, and the plurality of fasteners 135 can connect all the plurality of types of introduction nozzles 25 and only one of the plurality of types of introduction nozzles 25 is The detachable connection part 136 detachably coupled to the proximal end pipe part 43 is configured.

  For example, as shown in FIG. 8, the union nut 26 shown in FIG. 2 is eliminated and the mounting member 141 is fixed to the base 63 (not shown in FIG. 8) in place of the union bolt 62. The mounting member 141 is formed with an annular flange portion 142 projecting radially outward at an axial middle portion, and an external screw 143 is formed on the outer peripheral portion on the distal end side, and an annular ring on the distal end side relative to the external screw 143 Grooves 144 are formed. In addition, a cylindrical tubular portion 148 extending in the axial direction is formed in the proximal end tube portion 43, and a female screw 149 is formed in the inner circumferential portion thereof. Then, the O-ring 150 is disposed in the groove 144 at the tip of the mounting member 141, and the male screw 143 of the mounting member 141 is screwed on the female screw 149 of the proximal end pipe portion 43 until the flange 142 contacts the cylindrical portion 148. Let In this case, the male screw 143 and the female screw 149 can connect all of the plurality of types of introduction nozzles 25 and detachably connect only one of the plurality of types of introduction nozzles 25 to the proximal end tube portion 43. The end of the flange portion 142 on the male screw 143 side abuts on the proximal end pipe portion 43 to define the insertion length of the introduction nozzle 25 into the straight pipe portion 22. The contact portion 152 is formed.

  Further, as shown in FIG. 9, it is also possible to form a plurality of chlorine gas inlets 161 connected to the inner holes 95 in the base 63 of the introduction nozzle 25. In this case, the number of connections of the electrolytic cell 14 can be increased or decreased to increase or decrease the supply amount of chlorine gas.

  Moreover, as shown to Fig.10 (a), it is also possible to employ | adopt other shapes besides the shape of the above-mentioned introduction nozzle 25 which has the taper hole part 105 and the cylindrical hole part 106 above. For example, as shown in FIG. 10 (b), a reverse taper hole 171 having a smaller diameter toward the taper hole 105 is provided between the taper hole 105 and the cylindrical hole 106, or shown in FIG. 10 (c). Thus, a tapered outer peripheral surface 172 is formed on the outer peripheral portion on the tip end side of the nozzle main body 64 so as to decrease in diameter toward the tip end to make the outer diameter narrow at the tip and to make the diameter of the inner hole 95 constant throughout. As shown in FIG. 10D, the outer diameter of the nozzle main body 64, that is, the diameter of the outer peripheral surface 96 is made constant to the tip, and the diameter of the inner hole 95 is made constant over the whole, or shown in FIG. Thus, it is possible to form an annular V-shaped groove 173 in the outer peripheral portion on the tip end side of the nozzle main body 64.

  Here, the introduction nozzle 25 (see FIG. 10A) in which the diameter of the inner hole 95 gradually increases in diameter toward the tip at the tip end portion, and the introduction nozzle where the diameter of the inner hole 95 is constant throughout Using (25) (see FIG. 10 (c)), the suction pressure was tested when the introduction nozzle 25 of different length was attached to the cheese tube 24. In this test, conditions other than the length of the introduction nozzle 25 and the shape of the tip of the inner hole 95 were constant. The results are shown in FIG. As shown in FIG. 11, the diameter of the inner hole 95 in FIG. 10 (c) is smaller than the diameter of the inner hole 95 in FIG. 10 (a) as compared to the constant introduction nozzle 25 (normal nozzle in FIG. 11). It has been found that the introduction nozzle 25 (opening nozzle in FIG. 11) which is gradually tapered in diameter toward the tip of the tip portion has a larger absolute value of the suction pressure and can strongly suck.

  In the case of the introduction nozzle 25 in which the outer diameter shown in FIG. 10 (c) is narrowed at the tip, the gap 101 becomes large immediately before the mixing portion 111 and the flow velocity decreases and the negative pressure decreases, so the suction pressure of chlorine gas decreases. Sometimes. However, as shown in FIG. 10D, if the introduction nozzle 25 has a constant outer diameter, it is possible to prevent the negative pressure from decreasing. For this reason, it is preferable that the outer diameter of the introduction nozzle 25 does not narrow at the tip. In view of the above, the suction pressure can be further increased by the introduction nozzle 25 of FIGS. 10 (a) and 10 (b).

  Therefore, in preparation for changing the suction pressure, it is preferable to prepare a plurality of introduction nozzles 25 in which the angle of the tapered hole portion 105 at the tip of the inner hole 95 is made different. Further, in order to change the flow rate of chlorine gas, a plurality of types of introduction nozzles 25 may be prepared in which the inner diameter of the cylindrical hole portion 106 of the inner hole 95 is different. A plurality of types of replaceable introduction nozzles 25 may be prepared in which both the inner diameter of the portion 105 and the inner diameter of the cylindrical hole portion 106 are appropriately changed.

  The above-described electrolytic product mixing device 11 constitutes an electrolytic water producing device by mixing water with chlorine gas as an electrolytic product to generate electrolytic water. For example, as shown in FIG. 12, an electrolyzed water producing apparatus 182 comprising an electrolyzer 14 for electrolyzing hydrochloric acid having a predetermined concentration to generate chlorine gas, and a water supply pipe 181 for supplying water is configured. In the electrolyzed water production apparatus 182 shown in FIG. 12, pipes 184 attached to the outlet ports 183 of the plurality of electrolytic cells 14 are connected to the inlet ports 161 of the inlet nozzle 25 and pressurized as raw water, for example. A water supply pipe 181 for supplying tap water is connected to the cross pipe portion 23. At the time of driving the electrolyzed water production apparatus 182, water is supplied to the cross pipe portion 23 of the suction and mixing device 21 and water enters the gap 101 at high speed from the position of the inner opening 33 of the cross pipe portion 23 shown in FIG. It flows. On the other hand, in the electrolytic cell 14, electrolysis of hydrochloric acid water proceeds. The water that has passed through the gap 101 and has flowed further forward than the introduction nozzle 25 of the straight pipe portion 22 sucks the inner hole 95 of the introduction nozzle 25 and, as a result, is connected to the outlet 183 of the electrolytic cell 14 shown in FIG. The generated chlorine gas is ejected from the inner hole 95 shown in FIG. 9 to the mixing section 111 via the pipe 184 and mixed with the water in the straight pipe section 22.

  Moreover, the electrolysis product mixing apparatus 11 mentioned above comprises a processing apparatus by mixing the chlorine gas as electrolysis product with raw water, and sterilizing processing or deodorizing processing of raw water. Raw water in this case is, for example, water in a pool, bathing water in a bathing facility, water to be purified in a water purification plant, sewage, drainage, ballast water of a ship, and the like.

  As a ballast water treatment apparatus for purifying ballast water for ships, for example, as shown in FIG. 13, there is a ballast water treatment apparatus 191 for injecting seawater into a ballast water tank 194 of the ship. The ballast water treatment apparatus 191 includes a pipe line 195 for supplying seawater to the ballast water tank 194, a pump 192 provided in the pipe line 195 for pumping seawater, and seawater serving as ballast water pumped and pumped by the pump 192. And a filter 193 for filtering. And in this ballast water treatment apparatus 191, the electrolysis product mixing device 11 which consists of the electrolysis module 16 and suction mixing device 21 which were mentioned above in order to mix chlorine gas as an electrolysis product to seawater after filtration with a filter 193 Is used. That is, by introducing the total amount of seawater after filtration with the filter 193 into the cross pipe portion 23 of the suction mixer 21, the seawater is mixed with chlorine gas to sterilize the seawater. Sea water mixed with chlorine gas is poured into a ballast water tank 194 of the ship. In this case, the position of the filter 193 and the position of the pump 192 can be changed as appropriate. For example, the filter 193 may be arranged upstream of the pump 192 and arranged downstream of the electrolysis product mixing device 11 You may. Also, the pump 192 may be disposed downstream of the electrolysis product mixing device 11. Such a point is the same also in the aspect shown in the following FIGS. 14-16.

  Further, as shown in FIG. 14, as another ballast water treatment apparatus 201 for injecting seawater into the ballast water tank 194 of the ship, the pump 192 and the filter 193 similar to the above are provided in the pipeline 195 and the filter 193 is used. A bypass route 203 for bypassing a portion of seawater from the main route 202 for injecting seawater after filtration into the ballast water tank 194 of the vessel is provided, and a portion of the seawater flowing in the bypass route 203 is chlorinated by the electrolytic product mixing device 11 There are some that mix gas. In this ballast water treatment apparatus 201, the seawater in the bypass route 203 is introduced into the cross pipe portion 23 of the suction mixing device 21, thereby mixing this seawater with chlorine gas to sterilize the seawater. Then, the seawater mixed with chlorine gas in this way is joined to the main route 202, mixed with the seawater flowing in the main route 202, sterilized, and poured into the ballast water tank 194 of the ship. In this case, the seawater in the bypass route 203 is mixed with chlorine gas so as to have a high concentration by the electrolysis product mixing device 11, and the seawater in the bypass route 203 is mixed with the seawater flowing in the main route 202, Adjust the mixture to achieve the desired concentration of That is, the ballast water treatment apparatus 201 is of a type that dilutes ballast water having a high concentration of chlorine.

  Further, as shown in FIG. 15, as another ballast water treatment apparatus 211, it has a pump 212 for pumping ballast water from a ballast water tank 194 of a ship, and electrolytic products are produced in ballast water pumped and pumped by the pump 212. The mixing device 11 mixes chlorine gas and returns it to the ballast water tank 194. That is, by introducing the entire amount of ballast water pumped by the pump 212 into the cross pipe portion 23 of the suction mixer 21, the ballast water is mixed with chlorine gas to sterilize the ballast water, and then the ballast water tank Return to 194. The ballast water treatment apparatus 211 circulates the ballast water of the ballast water tank 194 through a pipe line 195 for sterilization treatment.

  In addition, as shown in FIG. 16, the other ballast water treatment apparatus 221 has the same pump 212 and pipe 195 as above, and ballast water tank 194 pumped and pumped by the pump 212 is used as a ballast water tank 194 of the ship. There is provided a bypass route 223 for bypassing a portion of ballast water from the main route 222 which is returned to the above, and a part of the ballast water flowing through the bypass route 223 is mixed with chlorine gas in the electrolytic product mixer 11. In this ballast water treatment apparatus 221, the ballast water of the bypass route 223 is introduced into the cross pipe portion 23 of the suction mixing device 21, thereby mixing chlorine gas with the ballast water to sterilize the ballast water. Then, the ballast water mixed with chlorine gas is merged with the main route 222, mixed with the ballast water flowing in the main route 222, sterilized, and returned to the ballast water tank 194 of the ship. In this case, the ballast water in the bypass route 223 is mixed with chlorine gas so as to have a high concentration by the electrolytic product mixer 11, and the ballast water in the bypass route 223 is mixed with the ballast water flowing in the main route 222, The mixture is adjusted so that the concentration of chlorine in the mixture is the desired concentration. The ballast water treatment device 221 circulates the ballast water of the ballast water tank 194 for sterilization treatment, and is of a type that dilutes ballast water having a high concentration of chlorine.

  In the embodiment, the suction and mixing apparatus 21 is described by exemplifying the case where the straight pipe portion 22 of the cheese pipe 24 is set to face in the horizontal direction, but the direction of the cheese pipe 24 may be any direction It can also be set.

  Here, the relationship between the outer diameter of the nozzle body 64, the inner diameter of the straight pipe portion 22, and the flow rate of the suction mixing device 21 will be considered.

In the case of a liquid, the relationship between the flow rate of the fluid flowing in the pipe and the flow rate is expressed by the following equation.
Q = C × A × V
Here, Q: flow rate [m ³ / s], C: outflow coefficient, A: flow path area [m ² ], V: flow rate [m / s]

V = √ (2g × P ÷)
From the application of Bernoulli's theorem,
Q = C × A × √ (2 × P ÷)
Where P: pressure (differential pressure) [MPa], ρ: fluid density [kg / m ³ ]
1 Pa = N / m = 1 [Kgm ⁻¹ s ⁻² ], density of water: == 1000 [kg / m ³ ]

When a cylinder with an outer diameter of 29 mm is inserted into a pipe with an inner diameter of 30.4 mm, the cross-sectional area A through which fluid flows is
A = (15.2 * 15.2 * 3.14)-(14.5 * 14.5 * 3.14)
= 65.3 [mm ² ]
= 6.53 x 10 ^-5 [m ² ]

When the secondary side of the suction mixing device 21 is open to the atmosphere, when the pressure of the raw water which is the driving water is 0.2 MPa, the flow rate Q is
Q = C × A × √ (2 × P ÷)
= 1 x 6.53 x 10 ^-5 x √ (2 x 0.2 x 1000000 ÷ 1000)
= 1.30 × 10 ⁻³ [m ³ / s]
= 4.64 [m ³ / h]

When measured as an approximate value, the flow rate was 4.05 [m ³ / h] at 0.195 MPa.
It is a flow of 4.64 [m ³ ] when it is calculated assuming that the outflow coefficient C = 1.
From this, the outflow coefficient was 4.05 / 4.64 = 0.873, and when this was calculated as 0.9, the flow rate was 4.18 [m ³ / h].

  When the outflow coefficient is calculated as 0.9, as shown in Table 1 below, theoretical design is possible regardless of the outer diameter of the nozzle main body 64 of the introduction nozzle 25 and the inner diameter of the straight pipe portion 22 of the cheese pipe 24 .

  As shown in Table 2 below, in the case of the caliber 40A (in the case of the suction mixing device 21 having a different pipe diameter from the above), when the outflow coefficient is calculated as 0.9, theoretical design was possible. There was no change in the outflow coefficient due to the difference in the outer diameter of the nozzle main body 64, and it was found that the same outflow coefficient can be used when the inner diameter of the straight pipe portion 22 is the same and it is not related to the outer diameter of the nozzle main body 64 .
