  However, in the electrolyzed water production apparatus described above, it is not easy to change the flow rate of the raw water to be diluted which is the mixing target of the electrolysis product generated by the electrolyzer. For example, the flow rate of the raw water to be diluted in the existing equipment is changed. In some cases, significant equipment upgrades are required. Such a problem is a common problem that may occur in a mixing treatment apparatus that mixes an electrolytic product generated by an electrolytic cell with raw water. Here, in addition to the electrolyzed water production apparatus, for example, there is a treatment apparatus that sterilizes or deodorizes water by mixing an electrolysis product generated by an electrolytic cell with water to be mixed.

At least one of the length and the cross-sectional area can be changed. Therefore, the raw water that causes the cheese tube to flow from the cross tube portion toward the tip tube portion 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 tube portion. The flow rate at the time can be changed. Therefore, the flow rate of raw water can be easily changed.

At least one of the length and the cross-sectional area can be changed. Therefore, the raw water that causes the cheese tube to flow from the cross tube portion toward the tip tube portion 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 tube portion. The flow rate at the time can be changed. Therefore, the flow rate of raw water can be easily changed.
The principle of the present invention is the same as that of an orifice flow meter (differential pressure flow meter), and when the flow is throttled in the middle of the pipe, the pressure of the fluid decreases. Since this change is related to fluid density and flow velocity, the flow rate can be determined by measuring the pressure difference between the upstream side and the downstream side. This flow rate is a volume flow rate and can be measured from a small flow rate to a large flow rate. Commercially available general flowmeters require fluid calibration before shipment to check the relationship between flow rate and output, but differential pressure flowmeters are manufactured and installed according to a specific throttle structure and pipe diameter range. If this is the case, actual flow calibration is unnecessary. For measuring instruments that require calibration, such as a flow meter, when the flow rate increases, initial costs and maintenance costs are high. However, in the present invention, the flow rate is guaranteed with the accuracy of the dimensional inspection at the diameter of the body portion of the introduction nozzle, which is very advantageous in terms of cost.

In Rukoto, changes at least one of the length and cross-sectional area of the gap between said introduction nozzle attached to the proximal tube portion straight pipe section.

  According to this configuration, a plurality of types of introduction nozzles that are detachable with respect to the base end pipe portion of the cheese pipe are selectively attached to the base end pipe portion, so that the gap between the introduction nozzle and the straight pipe portion is reduced. At least one of the length and the cross-sectional area is changed. Therefore, the raw water that causes the cheese tube to flow from the cross tube portion toward the tip tube portion 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 tube portion.

  Hereinafter, an electrolytic product mixing apparatus according to an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the electrolytic product mixing device 11 of the embodiment includes an electrolyte solution tank 12 that stores an electrolyte solution, an electrolyte solution pump 13 that sucks and discharges the electrolyte solution from the electrolyte solution tank 12, and an electrolyte solution pump. An electrolysis module 16 having an electrolytic cell 14 into which the electrolyte 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 electrolyte solution with electric power supplied from the electrolytic power supply 15. In addition, the electrolytic product mixing device 11 is sucked and mixed in which raw water is introduced under pressure and the electrolytic product generated by the electrolytic cell 14 is sucked and mixed with the raw water by the flow of the introduced raw water. A device 21 is provided.

  The electrolytic cell 14 electrolyzes the introduced electrolyte solution to generate an electrolytic product. Here, for example, the electrolyte solution contains chlorine ions such as an aqueous sodium chloride solution and an aqueous hydrochloric acid solution, 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 mixing device 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 for the electrolytic vessel 14 suitably. Hereinafter, the case where the electrolytic cell 14 generates chlorine gas as an electrolytic product will be described as an example.

  As shown in FIG. 2, the suction mixing device 21 includes a cylindrical straight pipe portion 22 that extends linearly, and a cylindrical cross that extends linearly and intersects the peripheral wall at an intermediate position in the axial direction of the straight pipe portion 22. T-shaped cheese tube 24 (Tee, Tees) having a tube part 23, an introduction nozzle 25 that is detachably provided on the cheese tube 24, and for attaching or removing the introduction nozzle 25 to or from the cheese tube 24 The union nut 26 is provided.

  The cross pipe part 23 is perpendicular to the central axis of the straight pipe part 22 and protrudes radially outward from the peripheral wall of the straight pipe part 22. The cross pipe portion 23 has an inner hole 31 having a constant diameter. As for the cross pipe part 23, the inlet 32 on the opposite side to the straight pipe part 22 is connected with the supply source of raw | natural water. That is, in the cheese pipe 24, raw water is introduced into the cross pipe part 23 from the introduction port 32, and the straight pipe part 22 is arranged on the downstream side of the cross pipe part 23 in the flow direction of the raw water. .

  In the straight pipe portion 22, the inner peripheral surface 41 is a cylindrical surface having a constant diameter regardless of the axial position, except for an 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 having a constant diameter.

  In the straight pipe portion 22, a portion on one side in the axial direction with respect to the cross pipe portion 23 is a base end pipe portion 43 that is closed by being connected to the introduction nozzle 25. A portion opposite to the end tube portion 43 is a tip tube portion 44. The distal end pipe portion 44 has a distal end opening portion 45 opposite to the axially intersecting tube portion 23 connected to a supply destination of raw water after chlorine gas mixing. That is, the distal end pipe part 44 is arranged on the downstream side of the cross pipe part 23 in the direction of the raw water flow. In other words, in the cheese tube 24, the cross tube portion 23 is on the upstream side in the flow direction of the raw water with respect to the tip tube portion 44, and the tip tube portion 44 is on the downstream side in the flow direction of the raw water with respect to the cross tube portion 23. . Therefore, raw water flows into the cheese tube 24 from the cross tube portion 23 toward the distal end tube portion 44. After the chlorine water is mixed with the chlorine water (described later), the raw water flows from the distal end portion 45 of the distal end tube portion 44. It is discharged toward the supplier.

  The proximal end pipe part 43 is formed with an annular flange part 48 protruding outward in the radial direction at the end part. The union nut 26 has a cylindrical shape, and an annular inner flange portion 51 protruding 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 move between the flange portion 48 as the union flange of the proximal end tube portion 43 and the cross tube portion 23. When the part 51 abuts on the flange part 48 of the proximal end pipe part 43, the movement in the direction away from the cross pipe part 23 is further restricted. When the inner flange portion 51 abuts on the flange portion 48 in this way, the female thread 52 of the union nut 26 is disposed on the outer side in the axial direction than the proximal end tube portion 43.

  The introduction nozzle 25 is inserted into the straight tube portion 22 of the cheese tube 24 from the proximal tube portion 43 and attached to the proximal tube portion 43. The introduction nozzle 25 is freely attachable and detachable repeatedly, that is, detachable from the proximal end pipe portion 43. The introduction nozzle 25 is fitted and fixed to a base end union bolt 62 formed on the outer peripheral portion on one side in the axial direction, and a base end union bolt 62 screwed into the internal thread 52 of the union nut 26. A cylindrical base 63 at the base end, a nozzle body 64 extending from the base 63 into the straight pipe portion 22 of the cheese tube 24, and a connection where one end side is attached to the opposite side of the straight pipe portion 22 of the base 63 And a tubular body 65. The other end side of the connecting pipe body 65 communicates with the electrolytic cell 14 shown in FIG.

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

  After the nozzle body 64 is inserted into the inner hole 42 of the straight tube portion 22 of the cheese tube 24 from the proximal tube portion 43 with the O-ring 78 disposed in the recess 77 of the union bolt 62, The end surface 76 on the concave portion 77 side of the union bolt 62 is brought into contact with the end surface 81 on the flange portion 48 side of the proximal tube 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 moves the flange portion 48 of the proximal end pipe portion 43. Press against the union bolt 62. At that time, the O-ring 78 of the recess 77 of the union bolt 62 comes into contact with the end surface 81 of the proximal end tube portion 43 and elastically deforms. Thereby, the O-ring 78 seals the gap between the union bolt 62 and the proximal end pipe portion 43. In this way, the introduction nozzle 25 is attached to the proximal end tube portion 43 of the cheese tube 24. From this state, when the threaded engagement of the female thread 52 of the union nut 26 with the male thread 61 of the union nut 26 is loosened and released, the introduction nozzle 25 is released from the connection to the proximal end pipe portion 43 of the cheese pipe 24. The base end pipe part 43 is removed.

  The introduction nozzle 25 has a union bolt 62 and a base 63 serving as a base end thereof arranged outside the straight pipe portion 22 without being inserted into the inner hole of the straight pipe portion 22 and attached to the cheese pipe 24 by a union nut 26. It becomes the attaching part 85 to be made. Further, the flange portion 48 of the proximal end tube portion 43, the union nut 26, and the union bolt 62 serve as an attachment / detachment connection portion 86 that removably connects the attachment portion 85 of the introduction nozzle 25 to the proximal end tube portion 43. Yes. That is, the detachable connecting portion 86 is a union joint (a universal union). The inner peripheral surface 88 of the inner flange portion 73 of the union bolt 62 has the same diameter as the inner peripheral 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 peripheral surface 41 of the straight pipe part 22 and the central axis line are made to coincide with each other.

  The end portion of the union bolt 62 on the male screw 61 side in the axial direction is an abutting portion 91 that abuts on the end surface 81 of the proximal tube portion 43 on the flange portion 48 side in the axial direction. 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 contacts the end portion of the proximal tube portion 43 in the axial direction. In this state, the abutment portion 91 of the union bolt 62 at the proximal end portion of the introduction nozzle 25 abuts on the proximal end tube portion 43 to define the insertion length of the introduction nozzle 25 into the straight tube portion 22. In other words, the protruding length of the nozzle body 64 from the abutting portion 91 is a predetermined length, and when the abutting portion 91 abuts on the proximal end tube portion 43, the distal end surface 94 of the nozzle body 64 of this predetermined length is directly straight. The tube portion 22 is positioned in the axial direction. The insertion length of the introduction nozzle 25 is such that the nozzle body 64 crosses the inner opening 33 of the cross pipe portion 23 in the axial direction of the straight pipe portion 22, and the front end portion 45 of the tip pipe portion 44 and the inner side of the cross pipe portion 23. The length is such that the front end surface 94 is located 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 through which the inner hole 95 penetrates in the axial direction. The outer peripheral surface 96 of the nozzle body 64 is a cylindrical surface having a constant diameter regardless of the axial position. The nozzle main body 64 is arranged with the straight pipe portion 22 and the central axis aligned with each other inside the straight pipe portion 22 in a state where the attachment portion 85 is attached to the proximal end pipe portion 43 of the cheese pipe 24 by the union nut 26. It will be. Therefore, the straight tube portion 22 of the cheese tube 24 is an outer tube disposed outside so as to cover the nozzle body 64 of the introduction nozzle 25, and the nozzle body 64 is disposed inside the straight tube portion 22. It is a tube.

  With the attachment portion 85 attached to the proximal end tube portion 43, the inner peripheral surface 41 of the straight tube portion 22, 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 them. 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 where the introduction nozzle 25 is attached to the straight pipe portion 22 of the cheese pipe 24. The gap 101 has a cylindrical shape, one end is closed by the base 63, and the opening 102 at the other end is located at the distal end position of the nozzle main body 64, and the distal end opening 45 is more than the nozzle main body 64 in the straight pipe portion 22. Open to the side. The gap 101 has the same length as the protruding length of the nozzle body 64 from the base 63, and is a length that crosses the inner opening 33 of the intersecting pipe portion 23 in the axial direction of the straight pipe portion 22. The raw water introduced into the cross pipe portion 23 flows through the gap 101 to reach a range where there is no nozzle body 64 in the tip pipe portion 44 from the opening 102 of the gap 101, and from the tip mouth portion 45 toward the supply destination. Flowing.

  The inner hole 95 of the introduction nozzle 25 communicates with the inside of the connecting pipe body 65, and thus flows the chlorine gas generated in the electrolytic cell 14 shown in FIG. As shown in FIG. 3, the inner hole 95 of the introduction nozzle 25 has a tapered hole portion 105 having a tapered shape whose diameter increases toward the distal end surface 94 at the distal end portion. A cylindrical hole 106 having a constant diameter is provided on the end side regardless of the axial position. An end of the tapered hole 105 opposite to the cylindrical hole 106 is an opening 107 of the inner hole 95.

  In the suction mixing device 21 shown in FIG. 2, pressurized raw water is introduced into the cross tube portion 23 of the cheese tube 24 and passes through the gap 101 between the nozzle body 64 and the straight tube portion 22. 22 reaches the distal end pipe portion 44 and flows toward the supply destination. The flow of raw water at that time 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 sucks chlorine gas as an electrolytic product from the electrolytic cell 14 through the inner hole 95. To do. Thus, chlorine gas is introduced from the inner hole 95 into the raw water and mixed in the mixing part 111 in the vicinity of the opening 107 in the inner hole 42 of the straight pipe part 22. In this way, raw water mixed with chlorine gas flows toward the supply destination. That is, the suction mixing device 21 is an ejector that sucks gaseous chlorine gas using raw water that is liquid as a driving fluid.

  Here, the specific example of the dimension of the part relevant to the flow of the raw | natural water and chlorine gas of the suction mixing apparatus 21 is demonstrated. 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 body 64 is φ29 mm, the inner diameter of the cylindrical hole portion 106 of the inner hole 95 of the introduction nozzle 25 shown in FIG. The depth of the portion 105 from the tip surface 94 of the nozzle body 64 is 25 mm, and the angle of the tapered hole portion 105 (the angle formed by two lines that appear when the tapered hole portion 105 is taken as a cross section in a plane including the central axis). It is 40 degrees. In this case, the gap 101 between the straight pipe portion 22 and the nozzle 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 apparatus 11 includes 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 these need to be distinguished, they are distinguished as an introduction nozzle 25 (A), an introduction nozzle 25 (B), an introduction nozzle 25 (C), and an introduction nozzle 25 (D). The parts related to each are similarly distinguished by adding (A), (B), (C), (D) to the reference numerals.

An introduction nozzle 25 (C) having a nozzle body 64 (C) shown in FIG. 4 and an introduction nozzle having a nozzle body 64 (D) shown in FIG. And a nozzle 25 (D). The nozzle body 64 (D) has the same length as the nozzle body 64 (C) and the same thickness 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 mounting portion 85 and the union nut 26 have a common shape. Therefore, both of the introduction nozzles 25 (A) to 25 (D) are connected to the same proximal end tube portion 43 by the union nut 26. On the other hand, it is detachable. In other words, the introduction nozzles 25 (A) to 25 (D) are all detachable from the proximal end tube portion 43 of the same cheese tube 24, and are alternatively selected to be the same cheese tube 24. It is attached to the proximal end pipe part 43 of the. In other words, the attachment / detachment connecting portion 86 for detachably connecting the attachment portion 85 of only one introduction nozzle 25 to the proximal end tube portion 43 is common to these introduction nozzles 25 (A) to 25 (D). All of the introduction nozzles 25 (A) to 25 (D) can be connected to the proximal end pipe portion 43. That is, the introduction nozzles 25 (A) to 25 (D) can be attached by being exchanged with respect to the proximal end pipe portion 43 of the same cheese pipe 24.

  When these introduction nozzles 25 (A) to 25 (D) are alternatively attached to the proximal end pipe portion 43 of the cheese pipe 24, the straight pipe portion 22 is compared with the case where the other introduction nozzles 25 are attached. At least one of the length of the gap 101 and the cross-sectional area 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 pipe portion 43. With reference to the length and cross-sectional area of 101 (A), the introduction nozzle 25 having the nozzle body 64 (B) shown in FIG. When (B) is selected and attached to the proximal end pipe portion 43, the gap 101 (B) has the same length as the gap 101 (A) and the sectional area becomes smaller. Further, the introduction nozzle 25 (C) having the nozzle body 64 (C) shown in FIG. 5C having the same length and the same thickness as the nozzle body 64 (A) is selected and attached to the proximal end pipe portion 43. As a result, the gap 101 (C) has the same cross-sectional area as the gap 101 (A) and a longer length. In addition, the introduction nozzle 25 (D) having the nozzle body 64 (D) shown in FIG. 5D that is long and thick with respect to the nozzle body 64 (A) is selected and attached to the proximal end pipe portion 43. As a result, the gap 101 (D) has a smaller cross-sectional area and a longer length than the gap 101 (A).

  In other words, the electrolytic product mixing device 11 includes 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 end pipe portion 43. In other words, the electrolytic product mixing method of mixing chlorine gas with raw water using the electrolytic product mixing device 11 prepares a plurality of types of introduction nozzles 25 (A) to 25 (D), and these introduction nozzles 25. By selectively attaching (A) to 25 (D) to the proximal end pipe part 43, the length of the gap 101 between the introduction nozzle 25 attached to the proximal end pipe part 43 and the straight pipe part 22, and At least one of the cross-sectional areas is changed.

  According to the embodiment described above, a plurality of types of introduction nozzles 25 that are detachable from the proximal end pipe part 43 of the cheese tube 24 are alternatively attached to the proximal end pipe part 43, At least one of the length of the gap 101 between the straight pipe portion 22 and the cross-sectional area can be changed. Therefore, the raw water that flows through the cheese tube 24 from the cross tube portion 23 toward the tip tube portion 44 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 tube portion 22. The flow rate when flowing through the gap 101 can be changed. Therefore, the flow rate of raw water can be easily changed.

  Specifically, as shown in FIG. 5A, when the introduction nozzle 25 (A) having the nozzle body 64 (A) is selected and attached to the proximal end pipe portion 43, four introduction nozzles are provided. In the case where each of 25 (A) to 25 (D) is attached, the flow rate of the raw water is the largest. Based on this flow rate, the introduction nozzle 25 (B) having the nozzle body 64 (B) shown in FIG. When attached to 43, the gap 101 (B) has the same length as the gap 101 (A) but has a smaller cross-sectional area, so the flow rate of the raw water is reduced. When the introduction nozzle 25 (C) having the nozzle body 64 (C) shown in FIG. 5C having the same length and the same thickness as the nozzle body 64 (A) is attached to the proximal end pipe portion 43, Since the gap 101 (C) has the same cross-sectional area as the gap 101 (A), the length of the gap 101 (C) is increased, so that the flow rate of raw water is reduced due to pressure loss. When the introduction nozzle 25 (D) having the nozzle body 64 (D) shown in FIG. 5 (d) that is long and thick with respect to the nozzle body 64 (A) is attached to the proximal end pipe portion 43. Since the gap 101 (D) has a smaller cross-sectional area and a longer length than the gap 101 (A), the flow rate of the raw water is reduced. When the introduction nozzle 25 (D) is attached, the flow rate of the raw water is reduced most in the case where each of the four introduction nozzles 25 (A) to 25 (D) is attached.

  Here, when the amount of chlorine gas generated by the electrolytic cell 14 is constant, the chlorine concentration of the raw water after mixing decreases as the flow rate of the raw water increases, and the chlorine concentration of the raw water after mixing increases as the flow rate of the raw water increases. Get higher. Further, 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 with the chlorine concentration kept constant.

  In the conventional electrolyzed water production apparatus as an example of the electrolysis product mixing apparatus, the scale of the facility is almost fixed by the capacity of the apparatus. Therefore, once the equipment is completed, changing the production capacity requires a large amount of money and labor. Large equipment and facilities are relatively easy to introduce at the time of new construction, but are often difficult to incorporate into existing facilities. Usually, the electrolyzed water production apparatus has a flow rate, an electrolysis capacity, and an electrolyzer size that are determined for each type of production apparatus, and a plurality of product specifications are prepared by the manufacturer. The customer will choose the best one accordingly. At that time, over-specification, lack of capability, etc. may occur. Moreover, it is not only a problem of capacity, but also has a drawback that the arrangement of piping and the size and shape of the apparatus do not fit into existing facilities. Until now, there was one model for one capability, and changing the capability required replacement of the device body, that is, preparation of another product or a plurality of devices. On the other hand, the electrolytic product mixing device 11 of the present embodiment can change the capacity by simply replacing the suction mixing device 21 with respect to the existing electrolytic product mixing device having a different structure, Capability can be changed at low cost.

  Also, when considering the cost reduction of the apparatus, the smaller the number of product items, the better as the parts are shared. However, in order to meet the customer's request, it is necessary to prepare a large number of items, which increases the cost. In addition, there was a problem that had some inventory as a product. On the other hand, the electrolytic product mixing apparatus 11 of the present embodiment can change the capacity only by replacing the introduction nozzle 25 and can share other parts. Therefore, even if the number of product items is increased, In particular, the number of items in the introduction nozzle 25 can be increased, and the total amount of inventory can be reduced.

  In addition, 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 whose diameter increases toward the tip end, chlorine gas as an electrolytic product can be efficiently sucked.

  In addition, since the proximal end portion of the introduction nozzle 25 is provided with an abutment portion 91 that abuts the proximal end tube portion 43 and defines the insertion length of the introduction nozzle 25 into the straight tube portion 22, the introduction nozzle When the abutment portion 91 is brought into contact with the proximal end tube portion 43 when the 25 is attached to the cheese tube 24, the insertion length of the introduction nozzle 25 into the straight tube portion 22 can be defined. Therefore, the introduction 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 only one mounting portion 85 of the plurality of types of introduction nozzles 25 is detachably connected to the proximal end tube portion 43 of the cheese tube 24. As the attachment / detachment connecting portion 86, it is possible to adopt other than the attachment / detachment connecting portion 86 having the above-described 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 a base 63 (not shown in FIG. 6) instead of the union bolt 62. An annular flange portion 122 projecting radially outward is provided at an end portion of the attachment member 121 opposite to the connection pipe body 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 between the clip members 123. The clip member 123 is formed by bending a band-shaped plate material and is elastically deformable. The clip member 123 is formed with a fitting groove 124, and the flange parts 48 and 122 are clamped by arranging the flange parts 48 and 122 in the fitting groove 124 and fitting them together at the same time. In this case, the flange portions 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 detached from the proximal end tube portion 43. The detachable connecting portion 125 that is freely connected is configured, and the distal end portion of the flange portion 122 of the mounting member 121 abuts on the proximal end tube portion 43 and is introduced into the straight tube portion 22 (in FIG. 6). The contact portion 126 defines the insertion length (not shown).

  Further, for example, as shown in FIG. 7, the union nut 26 shown in FIG. 2 is eliminated, and a perforated disk-shaped attachment member 131 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 increased in accordance with the mounting member 131. The mounting member 131 and the flange portion 48 are fastened by a plurality of fasteners 135 including bolts 133 and nuts 134 with the perforated disk-shaped packing 132 sandwiched between the mounting member 131 and the flange portion 48. In this case, the mounting member 131, the flange portion 48, the packing 132, and the plurality of fasteners 135 can connect all of the plurality of types of introduction nozzles 25, and only one of the plurality of types of introduction nozzles 25 can be connected. The detachable connecting portion 136 that is detachably connected to the proximal end tube portion 43 is configured.

  Further, 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) instead of the union bolt 62. The mounting member 141 is formed with an annular flange portion 142 projecting radially outward at an axially intermediate portion, a male screw 143 on the outer peripheral portion on the tip side, and an annular shape on the tip side of the male screw 143. The groove 144 is formed. Further, 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 on the inner peripheral portion thereof. Then, the O-ring 150 is disposed in the groove 144 at the distal end of the mounting member 141, and the male screw 143 of the mounting member 141 is screwed into the female screw 149 of the proximal end tube portion 43 until the flange portion 142 comes into contact with 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 only one of the plurality of types of introduction nozzles 25 is detachably connected to the proximal end tube portion 43. The detachable connecting portion 151 is configured, and the end portion of the flange portion 142 on the male screw 143 side is in contact with the proximal end tube portion 43 to regulate the insertion length of the introduction nozzle 25 into the straight tube portion 22. It becomes the contact part 152.

  Further, as shown in FIG. 9, a plurality of chlorine gas inlets 161 connected to the inner hole 95 can be formed in the base 63 of the inlet nozzle 25. In this case, the supply amount of chlorine gas can be increased or decreased by increasing or decreasing the number of connections of the electrolytic cell 14.

  In addition to the shape of the introduction nozzle 25 having the tapered hole portion 105 and the cylindrical hole portion 106 as shown in FIG. 10A, other shapes can be employed. For example, as shown in FIG. 10B, a reverse tapered hole 171 having a smaller diameter toward the tapered hole 105 side is provided between the tapered hole 105 and the cylindrical hole 106, or as shown in FIG. As described above, a tapered outer peripheral surface 172 having a smaller diameter toward the distal end side is formed on the outer peripheral portion on the distal end side of the nozzle body 64 so that the outer diameter is narrowed at the distal end, and the diameter of the inner hole 95 is made constant throughout As shown in FIG. 10D, the outer diameter of the nozzle body 64, that is, the diameter of the outer peripheral surface 96 is made constant up to the tip, and the diameter of the inner hole 95 is made constant throughout, or as shown in FIG. Thus, an annular V-shaped groove 173 can be formed on the outer peripheral portion of the nozzle body 64 on the tip side.

  Here, the introduction nozzle 25 (see FIG. 10A) in which the diameter of the inner hole 95 gradually increases in a tapered shape toward the tip at the tip, and the introduction nozzle in which the diameter of the inner hole 95 is constant throughout. 25 (see FIG. 10C), the suction pressure when the introduction nozzles 25 of different lengths were attached to the cheese tube 24 was tested. 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 result is shown in FIG. As shown in FIG. 11, the diameter of the inner hole 95 in FIG. 10A is larger than that of the introduction nozzle 25 (normal nozzle in FIG. 11) where the diameter of the inner hole 95 in FIG. It was found that the suction nozzle 25 (opening nozzle in FIG. 11) whose diameter gradually increased in a tapered shape toward the tip at the tip has a larger absolute value of suction pressure and can be sucked strongly.

  In the case of the introduction nozzle 25 whose outer diameter is narrowed at the tip as shown in FIG. 10C, the gap 101 becomes large immediately before the mixing section 111, the flow velocity is lowered, and the negative pressure is reduced, so that the suction pressure of chlorine gas is lowered. Sometimes. However, if the introduction nozzle 25 has a constant outer diameter as shown in FIG. 10D, the negative pressure can be prevented from decreasing. For this reason, it is preferable that the outer diameter of the introduction nozzle 25 is not constricted at the tip. In view of the above, the introduction nozzle 25 of FIGS. 10A and 10B can further increase the suction pressure.

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

  The electrolyzed product mixing apparatus 11 described above constitutes an electrolyzed water production apparatus by mixing water with chlorine gas as an electrolyzed product to produce electrolyzed water. For example, as shown in FIG. 12, an electrolyzed water production apparatus 182 including an electrolyzer 14 that electrolyzes hydrochloric acid having a predetermined concentration to generate chlorine gas and a water supply pipe 181 that supplies water is configured. In the electrolyzed water production apparatus 182 shown in FIG. 12, the pipes 184 attached to the respective outlets 183 of the plurality of electrolytic cells 14 are connected to the plurality of inlets 161 of the introduction nozzle 25 and pressurized, for example, as raw water. A water supply pipe 181 for supplying tap water is connected to the cross pipe portion 23. When the electrolyzed water production apparatus 182 is driven, water is supplied to the cross pipe section 23 of the suction mixing apparatus 21 and water enters the gap 101 at a high speed from the position of the inner opening 33 of the cross pipe section 23 shown in FIG. To flow. On the other hand, electrolysis of hydrochloric acid water proceeds in the electrolytic cell 14. The water that has passed through the gap 101 and has flowed forward from 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 unit 111 and mixed with the water in the straight pipe unit 22 through the pipe 184 formed.

  Moreover, the electrolysis product mixing apparatus 11 mentioned above comprises a processing apparatus by mixing the raw | natural water with the chlorine gas as an electrolysis product, and sterilizing or deodorizing raw | natural water. The raw water in this case is, for example, pool water, bath water of bathing facilities, purification target water of a water purification plant, sewage, drainage, ship ballast water, or 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 pouring seawater into a ballast water tank 194 of the ship. The ballast water treatment apparatus 191 includes a pipe 195 for feeding seawater to the ballast water tank 194, a pump 192 provided in the pipe 195 for pumping seawater, and seawater to be ballast water pumped and pumped by the pump 192. And a filter 193 for filtering. And in this ballast water treatment apparatus 191, in order to mix the chlorine gas as an electrolysis product with the seawater filtered by the filter 193, the electrolysis product mixing apparatus 11 which consists of the electrolysis module 16 and the suction mixing apparatus 21 mentioned above is mixed. Is used. That is, by introducing the entire amount of seawater filtered by the filter 193 into the cross pipe portion 23 of the suction mixing device 21, the seawater is sterilized by mixing chlorine gas with the seawater. Seawater after the chlorine gas is mixed 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 appropriately changed. For example, the filter 193 may be arranged upstream of the pump 192 or arranged downstream of the electrolytic product mixing device 11. You may do it. Further, the pump 192 may be arranged downstream of the electrolytic product mixing device 11. Such a point is also the same in the embodiments shown in FIGS.

  Further, as shown in FIG. 14, as another ballast water treatment apparatus 201 for pouring seawater into a ballast water tank 194 of a ship, a pipe 195 and a filter 193 similar to the above are provided in a pipe 195, and the filter 193 A bypass route 203 for bypassing a part of the seawater from the main route 202 for pouring the filtered seawater into the ballast water tank 194 of the ship is provided, and the seawater flowing through the bypass route 203 is subjected to chlorine by the electrolytic product mixing device 11. Some mix gas. In this ballast water treatment device 201, seawater of the bypass route 203 is introduced into the cross pipe portion 23 of the suction mixing device 21, so that chlorine gas is mixed with the seawater to sterilize the seawater. Then, the seawater mixed with chlorine gas in this way is joined to the main route 202 and mixed with the seawater flowing through the main route 202 to be sterilized and poured into the ballast water tank 194 of the ship. In this case, the chlorine gas is mixed with the seawater of the bypass route 203 so as to have a high concentration by the electrolytic product mixing device 11, and the seawater of the bypass route 203 is mixed with the seawater flowing through the main route 202, and then the chlorine gas of the seawater. The mixing is adjusted so that the concentration of is the desired concentration. That is, this ballast water treatment apparatus 201 is of a type that dilutes ballast water having a high chlorine concentration.

  Further, as shown in FIG. 15, as another ballast water treatment device 211, there is a pump 212 that pumps ballast water from a ballast water tank 194 of a ship, and electrolytic products are generated in the ballast water that is pumped and pumped by the pump 212. Some mixing devices 11 mix chlorine gas and return it to the ballast water tank 194. In other words, the entire amount of ballast water pumped by the pump 212 is introduced into the cross pipe portion 23 of the suction mixing device 21 so that the ballast water is sterilized by mixing chlorine gas with the ballast water, and then the ballast water tank. Return to 194. The ballast water treatment device 211 sterilizes the ballast water in the ballast water tank 194 by circulating it through a pipe line 195.

  Further, as shown in FIG. 16, as another ballast water treatment device 221, a ballast water tank 194 of a ship has a pump 212 and a pipe 195 similar to those described above, and the ballast water pumped up by the pump 212 and pumped. There is a bypass route 223 for bypassing a part of the ballast water from the main route 222 to be returned to, and a part of the ballast water flowing through the bypass route 223 is mixed with chlorine gas by the electrolytic product mixing device 11. In this ballast water treatment device 221, the ballast water of the bypass route 223 is introduced into the cross pipe portion 23 of the suction mixing device 21, whereby chlorine gas is mixed with this ballast water to sterilize the ballast water. The ballast water mixed with chlorine gas in this manner is merged with the main route 222 and mixed with the ballast water flowing through the main route 222 to be sterilized and returned to the ballast water tank 194 of the ship. In this case, chlorine gas is mixed with the ballast water of the bypass route 223 so as to have a high concentration by the electrolytic product mixing device 11, and the ballast water of the bypass route 223 is mixed with the ballast water flowing through the main route 222, and then the ballast water. The mixing is adjusted so that the chlorine concentration of the water becomes the desired concentration. This ballast water treatment device 221 circulates the ballast water in the ballast water tank 194 and sterilizes it, and is a system for diluting ballast water having a high chlorine concentration.

  In addition, in embodiment, although the suction mixing apparatus 21 illustrated and demonstrated the case where the straight pipe | tube part 22 of the cheese tube 24 was installed so that it might face a horizontal direction, what direction is the direction of the cheese tube 24? 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 liquid, the relationship between the flow rate of the fluid flowing in the pipe and the flow velocity 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 velocity [m / s]

V = √ (2g × P ÷ ρ)
From the application of Bernoulli's theorem,
Q = C × A × √ (2 × P ÷ ρ)
Here, P: pressure (differential pressure) [MPa], ρ: fluid density [kg / m ³ ]
1 Pa = N / m = 1 [Kgm ⁻¹ s ⁻² ], water density: ρ = 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,
A = (15.2 × 15.2 × 3.14) − (14.5 × 14.5 × 3.14)
= 65.3 [mm ² ]
= 6.53 × 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 that is the driving water is 0.2 MPa, the flow rate Q is
Q = C × A × √ (2 × P ÷ ρ)
= 1 × 6.53 × 10 ⁻⁵ × √ (2 × 0.2 × 1000000 ÷ 1000)
= 1.30 × 10 ⁻³ [m ³ / s]
= 4.64 [m ³ / h]

When measured by an approximate value, the flow rate was 4.05 [m ³ / h] at 0.195 MPa.
When the calculation is made assuming that the outflow coefficient C = 1, the flow rate is 4.64 [m ³ ].
From this, the outflow coefficient was 4.05 / 4.64 = 0.873. 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, a theoretical design is possible regardless of the outer diameter of the nozzle 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 a bore 40A (a suction mixing device 21 having a different pipe diameter from the above), a theoretical design was possible when the outflow coefficient was calculated as 0.9. There was no change in the outflow coefficient due to the difference in the outer diameter of the nozzle body 64, and when the straight pipe portion 22 had the same inner diameter, the same outflow coefficient could be used, and it was found that it was not related to the outer diameter of the nozzle body 64. .
