The embodiment of the invention provides a combined fluid distributor which is used in a reactor and can improve the mixing uniformity of liquid in the reactor. The reactor in the invention is an anaerobic reactor, a tower reactor and other devices. As shown in fig. 1 to 8, the combined fluid distributor comprises a plurality of main fluid pipes 1, a central bracket 4, a plurality of groups of circular arc branch pipes 2 and a plurality of liquid outlet pipes 3. Wherein each main fluid pipe 1 is a straight pipe having a first end 11 and a second end 12, the first end 11 being removably secured to the tank wall W of the reactor. The plurality of fluid main pipes 1 are uniformly distributed in the circumferential direction of the same circumferential plane P, and the second ends 12 are directed to the center O of the circumferential plane P. The center bracket 4 is detachably connected to the second end 12 of each main fluid pipe 1. Each set of circular arc branch pipes 2 is positioned between the adjacent main fluid pipes 1, and the circular arc branch pipes 2 are provided with a communication end 21 and a closed end 22, wherein the communication end 21 is communicated with the inside of the main fluid pipe 1, and the closed end 22 is completely closed. The groups of arc branch pipes 2 form at least one circular ring structure in the circumferential plane P. The liquid outlet pipe 3 is communicated with the arc branch pipe 2.
In an embodiment, as shown in fig. 1 and 3, the first end 11 of the main fluid pipe 1 has an external thread, which is connected with the tank wall W of the reactor in a sealing manner by a nut, so as to realize detachable connection of the main fluid pipe 1 with the tank wall W, or can realize detachable connection in other manners, which is not limited herein. In order to ensure the sealing performance, sealing gaskets are arranged on the inner side and the outer side of the tank wall W, and other sealing means can be adopted, so that the sealing method is not limited.
In one embodiment, since the fluid flows from the first end 11 to the second end 12 of the main fluid pipe 1, in order to reduce the difference in inlet pressure drop across the circular arc branch pipes 2 in the flow direction, in one embodiment, the inner diameter of the main fluid pipe 1 gradually decreases from the first end 11 to the second end 12 to facilitate uniform fluid flow at the communication end 21 of the circular arc branch pipes 2.
In one embodiment, at least one connection pipe 13 communicating with the inside of the fluid main pipe 1 is provided on the outer wall thereof. The connecting pipes 13 are short straight pipes, the number of which is the same as that of the arc branch pipes 2 of each group, for the purpose of communicating with the arc branch pipes 2. The connection pipe 13 may be provided on the outer wall of the main fluid pipe 1 by integral molding, welding, or the like, and is not limited herein. In one embodiment, the connecting tube 13 has external threads.
In one embodiment, as shown in fig. 1, the center support 4 includes a plurality of radial fixing pipes 41, and the number of fixing pipes 41 is the same as that of the main fluid pipes 1, and in this embodiment, the number of fixing pipes 41 is four. For example, the central support 4 is welded from a set of hollow steel tubes with external threads, each of the same length. The second end 12 of the main fluid pipe 1 is provided with an external thread, the diameter of the second end 12 is the same as that of the fixed pipe 41, and when the main fluid pipe 1 is installed, the second end 12 and the fixed pipe 41 are fixedly connected through the second threaded sleeve 6.
In an embodiment, the number of the arc branch pipes 2 in each group is plural, for example, two, three, four, six, etc., which are not limited herein. Each group of arc branch pipes 2 is arranged at intervals in the radial direction of the circumferential plane P, and the groups of arc branch pipes 2 form a concentric ring structure in the circumferential plane P and are concentric with the circumferential plane P, as shown in fig. 1. Each set of arc branches 2 has the same arc and has a different arc length. The main fluid pipe 1 thus divides the fluid distributor in several identical parts on the circumferential plane P, the number of which identical parts is identical to the number of main fluid pipes 1. Since the fluid flows in from the first end 11 of the main fluid pipe 1 and then into each of the arc branch pipes 2, the longer the arc branch pipe 2 is closer to the tank wall W, the smaller the water pressure thereof is, and thus the smaller the arc branch pipe is closer to the tank wall W, the smaller the fluid flow rate thereof is delivered to each of the liquid outlet pipes 3. In order to make the fluid flow obtained everywhere in the reactor the same, in one embodiment the spacing of each set of adjacent two circular arc branches 2 is set to taper radially outwards. Here, "outer" refers to the center O of the circle with respect to the circumferential plane P, which is "inner", and away from the center O to the outside, e.g., the direction from the second end 12 to the first end 11 of the fluid main 1 is the inside-out direction.
In an embodiment, the number of each set of arc branch pipes 2 may be one, and the plurality of sets of arc branch pipes 2 form a ring structure, and the ring structure is concentric with the circumferential plane P.
Regarding the connection of the circular arc branch pipe 2 to the main fluid pipe 1, the following manner may be adopted: the communication end 21 of the circular arc branch pipe 2 is integrally formed with the fluid main pipe 1, or the communication end 21 of the circular arc branch pipe 2 is welded to the outer wall of the fluid main pipe 1 and is communicated with the inside of the fluid main pipe 1. However, since a certain circular arc branch pipe 2 may be clogged during long-term use, for replacement convenience, in one embodiment, each circular arc branch pipe 2 is provided to be detachably connected with the main fluid pipe 1. Specifically, in one embodiment, as shown in fig. 4, the communication end 21 of the circular arc branch pipe 2 has external threads, as shown in fig. 3, the connection pipe 13 provided on the outer wall of the fluid main pipe 1 has external threads, and the outer diameter of the communication end 21 of the circular arc branch pipe 2 is the same as the outer diameter of the connection pipe 13. As shown in fig. 1-2, when assembling, a first threaded sleeve 5 is sleeved on the circular arc branch pipe 2 or the connecting pipe 13, the communication end 21 of the circular arc branch pipe 2 is aligned with the port of the connecting pipe 13, and the first threaded sleeve 5 is rotated to connect the two in a sealing way. In order to enhance the tightness, nuts may be respectively provided at both ends of the first threaded sleeve 5, and after the first threaded sleeve 5 is hermetically connected to the connection pipe 13 and the circular arc branch pipe 2, the nuts may be respectively screwed. In another embodiment, the connecting end 21 of the circular arc branch pipe 2 is in sealing connection with the connecting pipe 13 on the main fluid pipe 1 through a flange. Because the present application relates to the arc-shaped branch pipe, in order to simplify the assembly process, the arc-shaped branch pipe 2 is prevented from rotating as much as possible, and therefore, the fluid main pipe 1 is communicated with the arc-shaped branch pipe 2 in a way of rotating a connecting piece. Of course, other assembly modes may be adopted, such as that a through hole is formed in the main fluid pipe 1, the communication end 21 of the circular arc branch pipe 2 is directly inserted into the through hole, and the two are in interference fit, or a sealing sleeve is arranged outside the communication end 21 of the circular arc branch pipe 2, the communication end 21 of the circular arc branch pipe 2 is directly inserted into the through hole of the main fluid pipe 1, and sliding and sealing performance of the two are not ensured through the sealing sleeve. The manner of communication between the circular arc branch pipe 2 and the main fluid pipe 1 may be other, and is not limited herein.
In an embodiment, the closed end 22 of the circular arc branch pipe 2 is a free end or is connected with the outer wall of the adjacent main fluid pipe 1 through a fixing piece. Specifically, since the longer the arc length of the arc branch pipe 2 is, the more the arc branch pipe 2 is located on the outer side in the radial direction, the more the closed end 22 thereof needs to be supported, otherwise the arc branch pipe 2 is easily deformed or even broken. Therefore, the communication end 21 of the circular arc branch pipe 2 communicates with the main fluid pipe 1, and the closed end 22 thereof is fixedly connected with the adjacent main fluid pipe 1. Specifically, as shown in fig. 5, an upper fixing piece 7 is disposed at one side of the closed end 22 of the circular arc branch pipe 2, a lower fixing piece 8 is disposed on the outer wall of the adjacent fluid main pipe 1, the upper fixing piece 7 and the lower fixing piece 8 have the same structure and are provided with at least one threaded hole, and the upper fixing piece 7 and the lower fixing piece 8 are fastened and connected by bolts and nuts, so that the closed end of the circular arc branch pipe 2 is fastened and connected with the fluid main pipe 1.
In an embodiment, since the fluid flows from the communication end 21 to the closed end 22 of the circular arc branch pipe 2, in order to reduce the difference of pressure drops at the outlets where the circular arc branch pipes 2 are connected to the respective liquid outlet pipes 3, the inner diameter of the circular arc branch pipe 2 may be set to gradually decrease from the communication end 21 to the closed end 22 in order to facilitate the uniformity of the fluid flow at the outlets of the respective circular arc branch pipes 2.
A plurality of liquid outlet pipes 3 are communicated with each circular arc branch pipe 2, and fluid is sprayed into the reactor through the liquid outlet pipes 3. In one embodiment, as shown in fig. 4 and 6, the liquid outlet pipe 3 is a relatively short straight pipe, one end of which is communicated with the circular arc branch pipe 2, and the other end of which extends downward. In the present invention, "upper" and "lower" are defined as the top of the reactor, the bottom of the reactor, and the fluid is discharged from the top to the bottom. As shown in fig. 8, the liquid outlet pipe 3 has an angle α inclined radially outward with respect to the vertical direction of the circumferential plane P, 0 ° < α < 90 °, such as 30 °,45 °,60 °,80 °, etc., without limitation. As shown in fig. 7, the liquid outlet pipe 3 forms an angle β with the tangent line of the arc branch pipe 2 at the connection point of the arc branch pipe 2, and the angle β is 0 ° < β < 90 °, such as 30 °,45 °,60 °,70 °,80 °, etc., without limitation. The above arrangement mode makes the liquid outlet pipe 3 incline outwards radially, and meanwhile, the tangent line at the joint of the liquid outlet pipe 3 and the arc branch pipe 2 has an included angle beta, so that the fluid is ejected downwards and outwards from each liquid outlet pipe 3, and the ejected fluid drives the fluid in the tank to do rotary motion simultaneously, thus, under the driving of the fluid ejected from the outlet of each liquid outlet pipe 3 of the fluid distributor, the fluid in the reactor tank below the fluid distributor does downward and outwards spiral motion, and when the downward and outwards spiral flow hits the tank bottom and the tank wall, the downward and outwards spiral flow is converted into upward spiral flow, and the downward and outwards spiral flow enables the pressure of the center position of the reactor tank below the fluid distributor to be lower, so that the fluid above the fluid distributor flows in, and a three-dimensional spiral circulation flow with the center downwards and the periphery upwards is formed in the whole reactor tank. The generation of the three-dimensional circulation spiral flow in turn promotes the distribution uniformity of the liquid after entering the reactor tank from the fluid distributor, and improves the mass transfer effect and the reaction rate in the reactor tank.
The connection mode of the liquid outlet pipe 3 and the circular arc branch pipe 2 is similar to the connection mode of the circular arc branch pipe 2 and the fluid main pipe 1. Such as the liquid outlet pipe 3 and the arc branch pipe 2 are integrally formed or welded on the arc branch pipe 2. And for the convenience of replacement, each liquid outlet pipe 3 is detachably connected with the circular arc branch pipe 2. Specifically, in one embodiment, a connection end is disposed on the outer wall of the circular arc branch pipe 2, and is communicated with the inside of the circular arc branch pipe 2, and protrudes from the outer wall of the circular arc branch pipe 2 along the injection direction of the fluid in the liquid outlet pipe 3, the connection end has an internal thread, one end of the liquid outlet pipe 3 has an external thread, and the two threads are in threaded connection. Or the connecting end is provided with external threads, one end of the liquid outlet pipe 3 is provided with external threads, the external diameter of the liquid outlet pipe is the same as that of the liquid outlet pipe 3, and the liquid outlet pipe is connected through a threaded sleeve. Other connection methods are also possible, and are not limited herein.
In summary, the combined fluid distributor of the present invention is provided with the plurality of main fluid pipes 1, which are uniformly distributed in the circumferential direction of the same circumferential plane P, and the plurality of groups of arc branch pipes 2 are communicated with the main fluid pipes 1, and at least one circular structure is formed in the circumferential plane P, so that the combined fluid distributor is symmetrical in structure, the fluid ejected from the liquid outlet pipe 3 is more uniform, and the mixing uniformity of the liquid in the reactor is further improved.

The invention is capable of other embodiments and of being practiced and carried out in various ways.
