Description

Technical Field

[0001] The utility model relates to the technical field of gas distributors for oxidation towers, and particularly to a gas distributor for an oxidation tower. Background Art

[0002] According to a gas distributor with an anti-backflow double-ring distribution pipe and a bubbling tower disclosed in Chinese Publication (Announcement) No. CN116651329A, the gas distributor includes an air inlet pipe. One end of the air inlet pipe is an air inlet, and the other end is connected to an upper ring distribution pipe. A filter baffle is fixedly installed between the two ends of the air inlet pipe. A floating ball is placed between the filter baffle and the air inlet. The air inlet pipe between the floating ball and the air inlet includes at least one reduced-diameter section, the inner diameter of the reduced-diameter section becomes smaller and is smaller than the diameter of the floating ball. The liquid distributor in the bubbling tower is located below the gas distributor, and the liquid outlet of the liquid distributor is directly below the gas distribution holes of the upper ring distribution pipe. It avoids the backflow of liquid into the gas distributor, which causes pipeline corrosion, thereby shortening the service life of the ventilation pipe, increasing the intermediate gas distribution area, passing the gas holdup in the reactor, reducing the occurrence of gas dead zones. The higher the gas holdup, the faster the reaction rate, and greatly improves the working efficiency.

[0003] When the above technology is used, the gas can only be discharged from the distributor in a straight line and the gas discharge position is fixed and cannot be rotated. In this way, when gas-liquid mixing is carried out, the mixing efficiency is relatively low. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defect that in the prior art, the gas can only be discharged from the distributor in a straight line and the gas discharge position is fixed and cannot be rotated, resulting in relatively low gas-liquid mixing efficiency, and to propose a gas distributor for an oxidation tower.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A gas distributor for an oxidation tower includes an air inlet pipe. One side of the air inlet pipe is provided with a first ring distribution pipe, and one side of the first ring distribution pipe is provided with a second ring distribution pipe. Flanges are provided on the surfaces of both ends of the first ring distribution pipe and the second ring distribution pipe. Six air outlet pipes are provided on the top surface of the first ring distribution pipe, and seven air outlet pipes are provided on the top surface of the second ring distribution pipe. Rotating pipes are provided at the tops of the thirteen air outlet pipes. Sealing shafts are provided in the middle of the thirteen air outlet pipes and the thirteen rotating pipes. Cyclones are provided inside the thirteen rotating pipes. Fixing frames are provided outside the thirteen cyclones. Flow dividing plates are provided at the bottom surfaces of the thirteen cyclones. Card slots are provided on the inner walls of the thirteen air outlet pipes. Clamping blocks are provided at the bottom surfaces of the thirteen rotating pipes.

[0006] Preferably, the air inlet pipe penetrates through the first ring distribution pipe, and the air inlet pipe is communicated with the first ring distribution pipe.

[0007] Preferably, the first annular distribution pipe and the second annular distribution pipe are connected by flanges at both ends, and the flanges are welded to both ends of the first annular distribution pipe and the second annular distribution pipe.

[0008] Preferably, the outlet pipes are welded to the bottom surfaces of the first annular distribution pipe and the second annular distribution pipe, and the outlet pipes communicate with the first annular distribution pipe and the second annular distribution pipe.

[0009] Preferably, the outlet pipe and the rotating pipe are connected by a sealing shaft, and the clamping block of the rotating pipe is installed in the clamping groove on the inner wall of the outlet pipe.

[0010] Preferably, the inner wall of the fixing frame is welded to the middle surface of the cyclone, and the outer wall of the fixing frame is welded to the inner surface of the rotating pipe.

[0011] Preferably, the flow dividing plate is welded to the bottom surface of the cyclone, and the flow dividing plate is conical.

[0012] Advantageous Effects

[0013] In the present utility model, the inlet pipe is welded to the surface of the first annular distribution pipe, and the first annular distribution pipe and the second annular distribution pipe are connected by flanges. The outlet pipes are welded to the top surfaces of the first annular distribution pipe and the second annular distribution pipe, and the rotating pipe and the outlet pipe are connected by a sealing shaft. The cyclone inside the rotating pipe is fixed to the inner wall of the rotating pipe by a fixing frame welded to the surface. A flow dividing plate is provided on the bottom surface of the cyclone. When in use, gas enters the first annular distribution pipe and the second annular distribution pipe through the inlet pipe, and the gas is transported into the rotating pipe through the outlet pipes on the top surface. The gas entering the rotating pipe will be evenly divided into the cyclone by the flow dividing plate on the bottom surface of the cyclone, and the gas will be discharged from the rotating pipe in a spiral manner through the arc-shaped channels on the surface of the cyclone. The spiral gas increases the mixing with the liquid. Since a reverse force will be generated when the gas discharges from the rotating pipe, this reverse force will push the rotating pipe to rotate, thereby changing the position of the gas discharge and further increasing the range of gas discharge to further increase the gas-liquid mixing, solving the drawback that the gas can only be discharged from the distributor in a straight line and the position of the gas discharge is fixed and cannot rotate, resulting in a low efficiency of gas-liquid mixing.

However, the following embodiments are only the preferred embodiments of the present utility model, not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.

[0022] The specific embodiments of the present utility model will be described below with reference to the accompanying drawings. Specific Embodiment 1:

On one side of the first annular distribution pipe 3, there is a second annular distribution pipe 4. Flanges 2 are provided on the end surfaces of both ends of the first annular distribution pipe 3 and the second annular distribution pipe 4. Six outlet pipes 5 are provided on the top surface of the first annular distribution pipe 3, and seven outlet pipes 5 are provided on the top surface of the second annular distribution pipe 4. Rotating pipes 6 are provided at the tops of the thirteen outlet pipes 5. Sealing shafts 7 are provided in the middle of the thirteen outlet pipes 5 and the thirteen rotating pipes 6.

Diverting plates 10 are provided on the bottom surfaces of the thirteen cyclones 8. Card slots 9 are provided on the inner walls of the thirteen outlet pipes 5. Clamping blocks 11 are provided on the bottom surfaces of the thirteen rotating pipes 6. The inlet pipe 1 penetrates through the first annular distribution pipe 3, and the inlet pipe 1 is communicated with the first annular distribution pipe 3. The first annular distribution pipe 3 and the second annular distribution pipe 4 are connected through the flanges 2 at both ends, and the flanges 2 are welded to the two ends of the first annular distribution pipe 3 and the second annular distribution pipe 4 respectively. The outlet pipes 5 are welded to the bottom surfaces of the first annular distribution pipe 3 and the second annular distribution pipe 4, and the outlet pipes 5 are communicated with the first annular distribution pipe 3 and the second annular distribution pipe 4. The outlet pipes 5 are connected to the rotating pipes 6 through the sealing shafts 7, and the clamping blocks 11 of the rotating pipes 6 are installed in the card slots 9 on the inner walls of the outlet pipes 5. The inner walls of the fixed frames 12 are welded to the middle surfaces of the cyclones 8, and the outer walls of the fixed frames 12 are welded to the inner wall surfaces of the rotating pipes 6. The diverting plates 10 are welded to the bottom surfaces of the cyclones 8, and the diverting plates 10 are conical in shape.

[0025] The intake pipe 1 penetrates and is welded at the middle position of the first annular distribution pipe 3, and the intake pipe 1 is connected to the first annular distribution pipe 3. The first annular distribution pipe 3 and the second annular distribution pipe 4 are connected by flanges 2 at both ends, and the four flanges 2 are evenly welded at both ends of the first annular distribution pipe 3 and the second annular distribution pipe 4. Six outlet pipes 5 are welded on the top surface of the first annular distribution pipe 3, and seven outlet pipes 5 are welded on the top surface of the second annular distribution pipe 4. The intervals between the outlet pipes 5 are equal. Rotating pipes 6 are provided at the tops of the thirteen outlet pipes 5, and the outlet pipes 5 and the rotating pipes 6 are connected by a sealing shaft 7 in the middle. The stator of the sealing shaft 7 is welded to the top end of the outlet pipe 5, and the rotor of the sealing shaft 7 is welded to the bottom end of the rotating pipe 6. In this way, the rotating pipe 6 can rotate through the sealing shaft 7. When the rotating pipe 6 is installed on the outlet pipe 5, the clamping block 11 welded to the bottom surface of the rotating pipe 6 will be stuck into the clamping groove 9 welded to the inner wall of the outlet pipe 5. Both the clamping block 11 and the clamping groove 9 are circular rings. In this way, the installed clamping block 11 and clamping groove 9 will further reduce the loss of gas and can also provide a positioning function during installation. The swirler 8 inside the rotating pipe 6 is fixed to the inner wall of the rotating pipe 6 through a fixing frame 12 welded to the middle surface of the swirler 8. The inner wall of the fixing frame 12 is welded to the surface of the swirler 8, and the outer wall of the fixing frame 12 is welded to the surface of the inner wall of the rotating pipe 6. In this way, the installation can fix the swirler 8 inside the rotating pipe 6. A flow dividing plate 10 is welded to the bottom surface of the swirler 8. When in use, gas enters the first annular distribution pipe 3 through the intake pipe 1. Since the first annular distribution pipe 3 and the second annular distribution pipe 4 are connected, the gas will flow into the second annular distribution pipe 4. When the first annular distribution pipe 3 and the second annular distribution pipe 4 are filled with gas, the gas will flow into the rotating pipe 6 through the outlet pipes 5 on the top surface. The gas entering the rotating pipe 6 will be evenly divided into the swirler 8 by the flow dividing plate 10 at the bottom surface of the swirler 8, and the gas will be discharged from the rotating pipe 6 in a spiral manner through the arc-shaped channels on the surface of the swirler 8. The spiral gas increases the mixing with the liquid. Since a reverse force will be generated when the gas is discharged from the rotating pipe 6, this reverse force will push the rotating pipe 6 to rotate, thereby changing the position of the gas discharge and further increasing the gas discharge range to further increase the gas-liquid mixing. Specific Embodiment Two:

[0027] Refer to Figures 1-5, An oxidation tower gas distributor. Further based on the basic structure in the first specific embodiment, a circular distribution pipe can be provided in the middle of the first annular distribution pipe 3 and the second annular distribution pipe 4. Connecting pipes are provided on both sides of the circular distribution pipe, and the two connecting pipes are respectively connected to the intake pipe 1 and the second annular distribution pipe 4. The connecting pipes are connected to the intake pipe 1 and the second annular distribution pipe 4 through flanges 2. On the top surface of the circular distribution pipe, there are also air outlet pipes 5, sealing shafts 7, rotating pipes 6, cyclones 8, fixing frames 12 and flow dividing plates 10 that are the same as those of the first annular distribution pipe 3 and the second annular distribution pipe 4. The air outlet pipes 5 are welded on the top surface of the circular distribution pipe, and the rotating pipe 6 is connected to the air outlet pipe 5 through the sealing shaft 7. The cyclone 8 is fixed inside the rotating pipe 6 through the fixing frame 12. In this way, when the gas enters the intake pipe 1, the gas enters the circular distribution pipe through the connecting pipe connected to the intake pipe 1. When the gas inside the circular distribution pipe is full, the gas will flow into the rotating pipe 6 through the air outlet pipe 5 on the top surface. The gas entering the rotating pipe 6 will be evenly divided into the cyclone 8 by the flow dividing plate 10 at the bottom of the cyclone 8. The gas is discharged from the rotating pipe 6 in a spiral manner through the arc-shaped channels on the surface of the cyclone 8. The spiral gas increases the mixing with the liquid. Since a reverse force is generated when the gas discharges from the rotating pipe 6, this reverse force will push the rotating pipe 6 to rotate, thereby changing the position of the gas discharge and further increasing the range of gas discharge to further increase the gas-liquid mixing. By adding a smaller circular distribution pipe in the middle, the efficiency of gas-liquid mixing is further increased.

[0028] In summary:

[0029] 1. The intake pipe 1 is welded on the surface of the first annular distribution pipe 3, and the first annular distribution pipe 3 and the second annular distribution pipe 4 are connected through the flange 2. The air outlet pipes 5 are welded on the top surfaces of the first annular distribution pipe 3 and the second annular distribution pipe 4, and the rotating pipe 6 and the air outlet pipe 5 are connected through the sealing shaft 7. The cyclone 8 inside the rotating pipe 6 is fixed on the inner wall of the rotating pipe 6 through the fixing frame 12 welded on the surface. A flow dividing plate 10 is provided at the bottom of the cyclone 8. When in use, the gas enters the first annular distribution pipe 3 and the second annular distribution pipe 4 through the intake pipe 1, and the gas is transported into the rotating pipe 6 through the air outlet pipe 5 on the top surface. The gas entering the rotating pipe 6 will be evenly divided into the cyclone 8 by the flow dividing plate 10 at the bottom of the cyclone 8. The gas is discharged from the rotating pipe 6 in a spiral manner through the arc-shaped channels on the surface of the cyclone 8. The spiral gas increases the mixing with the liquid. Since a reverse force is generated when the gas discharges from the rotating pipe 6, this reverse force will push the rotating pipe 6 to rotate, thereby changing the position of the gas discharge and further increasing the range of gas discharge to further increase the gas-liquid mixing. This solves the drawback that the gas can only be discharged from the distributor in a straight line and the position of the gas discharge is fixed and cannot rotate, resulting in a low efficiency of gas-liquid mixing.
