Description

Technical Field

[0001] The invention relates to the technical field of accessories for plate tower equipment, in particular to a fixed float valve type high-efficiency tower plate. Background Art

[0002] A plate tower is a mass transfer device used for graded contact of gas-liquid or liquid-liquid systems. A plate tower usually includes multiple tower plates arranged at intervals. The gas phase passes through bubbling units such as float valves and bubble caps arranged on the tower plates from the bottom of the tower plates, mixes with the liquid phase flowing horizontally above the tower plates, and then enters the tower plates of the upper layer. The liquid phase enters the tower plates of the lower layer through downcomers.

[0003] With existing float valves, since most gases come out through small holes of similar shapes, the flux is not large, and the bubble outlet position and direction are relatively single. If the liquid level on the tower plate is too high, vortexes and backmixing are easily formed, resulting in unstable operation, low efficiency, and high steam consumption. At the same time, if the float valve is not cleaned in time for a long time, a lot of impurities such as dust, dirt, and fiber will remain on the float valve, affecting the use effect of the float valve.

[0004] Therefore, the present application provides a fixed floating valve type high-efficiency tower tray to meet the demand. Summary of the invention

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above scheme, the gas phase is diverted by setting a diverter gas guide box assembly, and the gas flow rate is increased. At the same time, the gas entering the gas guide pipe is directly sprayed in a large range around the direction of the gas guide pipe, and contacts the gas-liquid two-phase with the surrounding horizontally flowing liquid phase. The gas sprayed through the square air outlet will be guided by the side wing plate, and the side wing plate is inclined toward the middle to prevent the liquid from flowing back and mixing. At this time, the gas enters the bottom of multiple arc-shaped discs at a high speed, and is guided by the inverted bowl shape of the arc-shaped disc, and is sprayed uniformly in a large range around and below, and sprayed onto the liquid phase on the top of the tower plate, and impacts the gas phase directly sprayed out of the gas guide pipe and the gas-liquid two-phase being mixed, destroying the overall liquid tension, avoiding excessive tension between liquids, too high liquid level depth, and preventing the liquid at the bottom of the liquid surface from not contacting the gas. At the same time, the contact time and contact area between the gas phase and the liquid phase are increased, and the exchange efficiency of the gas-liquid two-phase is improved. The gas phase is sprayed at different heights, directions and shapes to eliminate eddy currents and back mixing, improve the contact and heat exchange of the gas-liquid phase, and meet the needs of increasing the processing capacity.

[0019] By setting up an arc-shaped guide plate assembly, since there is still a certain gap between the arc-shaped disc and the hole wall at the top of the tower plate and the outside of the arc-shaped protrusion, the gas phase will blow up the liquid flowing around the baffle ring and blow a part of it into the arc-shaped disc, mix it on the inside of the arc-shaped disc, and enter the air inlet at the center point from the outer edge of the arc-shaped disc. When it reaches the round cover raised by the feet on the top of multiple arc-shaped discs through the air inlet, it will be resisted and rebounded by the bottom of the round cover. The liquid will rebound from the air inlet to the collection box. When it gushes out, the narrow gap inside the wire disc in the collection box will block the dirt, fiber and other impurities in the liquid and keep them in the collection box. This reciprocating process makes it convenient to collect impurities in the liquid, prevent the float valve from being blocked, reduce the resistance of the blockage itself, improve the mass transfer effect, and reduce steam consumption.

[0020] By setting up the sliding box assembly, the float valve can be easily and quickly disassembled, and the surface of the tower plate can be cleaned separately. The arc-shaped disc that was previously threadedly connected with the screw and fixedly clamped with the collecting box can be pulled up and cleaned separately. Finally, the wire disc in the collecting box can be taken out, the collecting box can be cleaned and replaced with a new wire disc, and finally the installation can be carried out in the reverse order of the above disassembly. The maintenance is very convenient, which improves the convenience of use and service life of the float valve and tower plate, and increases production capacity. It has good application and promotion value in the same industry. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The valve top assembly 2 includes a top cover 20 , which is disposed on the top of the retaining ring 10 . A knob 21 is installed on the top of the top cover 20 , and a screw rod 22 is installed on the bottom of the knob 21 .

[0047] The bottom of the top cover 20 is in close contact with the top of the retaining ring 10 , and the knob 21 and the screw rod 22 are rotatably connected to the central part of the top cover 20 .

[0048] like Figures 6 to 10 As shown, the arc guide plate assembly 3 includes an arc dish 30, which is arranged below the top cover 20, and the number of the arc dishes 30 is set to be multiple. The outer surface of the arc dish 30 is provided with multiple air inlet holes 31, a pad 32 is installed on the top of the arc dish 30, a round cover 33 is installed on the top of the pad 32, and a fixing hole 34 is opened in the center of the arc dish 30. The round cover 33 on the top of the topmost arc dish 30 among the multiple arc dishes 30 is tightly fitted with the bottom surface of the top cover 20, and the screw 22 is inserted into the fixing hole 34.

[0049] In this embodiment, after the staff in this field installs the floating valve type high-efficiency tower plate, the distillation system is turned on, and the gas phase formed by the steam forms a gas-liquid contact with the liquid flowing through the top of the tower plate 1. Specifically, when the steam is sprayed to the bottom of the tower plate 1, it will first enter the bottom expansion mask 11 to gather the gas, and use the driving force of the gas to push the conical guide plate 46 at the bottom of the floating valve upward. At this time, the valve top assembly 2 is lifted up and no longer covers the baffle ring 10. The sliding frame 50 of the sliding box assembly 5 slides upward in the hole of the tower plate 1, pushing the arc guide plate assembly 3 and the diversion gas guide box assembly 4 upward to expose the top of the baffle ring 10 of the tower plate 1, and opening the gas phase flow output. The gas is guided by the gas guide plate 45, a part of it enters the gas guide pipe 42, and the other part is sprayed out from the square air outlet 47 at the top of the guide plate 46, so as to divert the gas phase, increase the flow rate, and avoid vortices and backmixing caused by conventional structures.

[0050] like Figures 11 to 15 As shown, the split air guide box assembly 4 includes an air guide box body 40, which is arranged below the arc-shaped disc 30, a bottom plate 41 is installed at the bottom of the air guide box body 40, a collecting box 43 is installed at the top of the air guide box body 40, a plurality of air guide tubes 42 are installed around the inner wall of the bottom plate 41, an arc-shaped protrusion 44 is installed at the bottom of the bottom plate 41, and a plurality of air guide plates 45 are arranged at the bottom of the arc-shaped protrusion 44, the bottom end of the screw 22 is threadedly connected with the threaded sleeve at the center of the inner wall of the collecting box 43, the top cover 20 and the arc-shaped disc 30 are fixed to the top of the collecting box 43, the outer surface of the air guide box body 40 is arranged in an arc-shaped arch shape, and the top of the collecting box 43 is closely attached to the bottommost one of the plurality of arc-shaped discs 30. Directly below the arc-shaped disc 30, the bottom plate 41 is configured to be a truncated cone with a narrow upper part and a wide lower part. Both ends of the air guide pipe 42 are open, and the top bend is configured to be bent and flow outward. The air guide plate 45 is configured to be arc-shaped and thin. The bottom end of the air guide pipe 42 is adjacent to the arc-shaped protrusion 44 and the air guide plate 45. A wire reel 49 is provided inside the collecting box 43. The wire reel 49 is composed of a steel wire wound with austenitic stainless steel material. A guide plate 46 is sleeved on the outer surface of the air guide box body 40. A plurality of groups of square air outlet holes 47 are arranged on the outer surface of the guide plate 46 in a surrounding manner. Side wing plates 48 are installed on both sides of the top edge of the square air outlet hole 47, and the side wing plates 48 on both sides of the square air outlet hole 47 are inclined 15 degrees to the middle.

[0051] In this embodiment, the gas entering the air guide pipe 42 is directly sprayed in a wide range around the direction of the air guide pipe 42, and contacts the liquid phase of the surrounding transverse flow. The gas sprayed out through the square outlet 47 will be guided by the side wing plate 48. At this time, the gas enters the bottom of the multiple arc-shaped discs 30 at a high speed, and is guided by the inverted bowl shape of the arc-shaped discs 30, and is uniformly sprayed in a wide range around and below, and sprayed onto the liquid phase on the top of the tower plate 1. It is sprayed at different heights, directions and shapes, and contacts with the guide pipe. The gas phase directly ejected from the gas pipe 42 impacts the gas-liquid two phases being mixed, destroying the overall liquid tension, avoiding excessive tension between the liquids, excessive liquid depth, and the liquid at the bottom of the liquid surface not being able to contact the gas, while increasing the contact time and contact area between the gas phase and the liquid phase, and improving the exchange efficiency of the gas-liquid two phases. Since there is a certain gap between the arc-shaped disc 30 and the hole wall at the top of the tower plate 1 and the outer side of the arc-shaped protrusion 44, the outer shape of the arc-shaped protrusion 44 can reduce resistance. At this time, the gas phase will flow through the retaining ring 10 The surrounding liquid is blown up, and a part of it is blown into the arc-shaped disc 30, where it is mixed on the inner side of the arc-shaped disc 30, and at the same time, it enters the air inlet 31 at the center point from the outer edge of the arc-shaped disc 30. When it reaches the round cover 33 at the top of the multiple arc-shaped discs 30 supported by the feet 32 ​​through the air inlet 31, it will be resisted and rebounded by the bottom of the round cover 33. The liquid will rebound from the air inlet 31 to the collection box 43, which will receive the liquid and gush out when the liquid reaches the highest liquid level. However, when it gush out, the steel wire in the collection box 43 The narrow gap inside the disk 49 will block impurities such as dirt and fiber in the liquid and retain them in the collection box 43. This reciprocating process can collect impurities in the liquid to prevent excessive impurities from remaining on the surface of the float valve and affecting the use effect of the float valve. The wire disk 49 is composed of austenitic stainless steel wire, which is corrosion-resistant. The square air outlet holes 47 arranged in a surrounding manner can vent air in a surrounding manner, which just fits the shape of the arc-shaped disc 30 and can better form an impact with the liquid on the bottom surface of the arc-shaped disc 30.

[0052] like Figures 6 to 9 As shown, the slide box assembly 5 includes a sliding frame 50, the surface of the sliding frame 50 is smooth and is slidably arranged on the inner wall of the hole at the top of the tower plate 1, a torsion spring shaft 51 is installed at the bottom of the edge of the sliding frame 50, a limiting plate 52 is elastically arranged at the bottom end of the torsion spring shaft 51, a limiting ring 53 is installed at the bottom end of the limiting plate 52, and the limiting ring 53 is also slidably arranged on the inner wall of the hole at the top of the tower plate 1, the limiting ring 53 is always stuck under the retaining ring 10, the number of the limiting rings 53 is set to two groups, and the torsion spring shaft 51 has an elastic force to expand outward, and a gap is left between the ends of the two groups of limiting rings 53.

[0053] In this embodiment, the staff first manually pulls the knob 21 upwards to pull the limit ring 53 at the bottom of the sliding frame 50 to the inner side of the retaining ring 10, and then holds the top cover 20 above the sliding frame 50 with the palm of the hand, and directly pulls the top cover 20 upward with force. When pulling it out, the limit ring 53 is blocked by the retaining ring 10, and the limit ring 53 will rotate toward the middle through the limit plate 52 and the torsion spring shaft 51, and the gaps at both ends of the two limit rings 53 are closed, so that the limit ring 53 can be smoothly pulled out of the inner side of the retaining ring 10, and the float valve can be removed at this time, achieving the effect of easy maintenance.

[0054] The working principle of the technical solution provided by the present invention is as follows:

[0055] First, after installing the floating valve type high-efficiency tower plate, the staff in this field opens the distillation system, and the gas phase formed by the steam forms a gas-liquid contact with the liquid flowing through the top of the tower plate 1. Specifically, when the steam is sprayed to the bottom of the tower plate 1, it will first enter the bottom expansion mask 11 to gather the gas, and use the driving force of the gas to push the conical guide plate 46 at the bottom of the floating valve upward. At this time, the valve top assembly 2 is lifted up and no longer covers the baffle ring 10. The sliding frame 50 of the sliding box assembly 5 slides upward in the hole of the tower plate 1, pushing the arc guide plate assembly 3 and the diversion gas guide box assembly 4 upward to expose the top of the baffle ring 10 of the tower plate 1, and opening the gas phase flow output (the bottom of the arc-shaped guide plate 46 can reduce the resistance of the gas when it flows through). The gas is guided by the gas guide plate 45, a part of it enters the gas guide pipe 42, and the other part is ejected from the square air outlet 47 at the top of the guide plate 46.

[0056] The gas entering the air duct 42 is directly sprayed in a large range around the air duct 42, and contacts the gas-liquid two-phase with the surrounding horizontally flowing liquid phase, and the gas sprayed through the square outlet 47 will be guided by the side wing plate 48 (the side wing plate 48 is inclined 15 degrees to the middle to prevent the liquid from flowing back and mixing). At this time, the gas enters the bottom of the multiple arc-shaped discs 30 at a high speed, and is guided by the inverted bowl shape of the arc-shaped discs 30, and is sprayed uniformly in a large range around and below, and sprayed onto the liquid phase on the top of the tower plate 1. It is sprayed at different heights, directions and shapes, and impacts the gas phase directly sprayed out of the air duct 42 and the gas-liquid two-phase being mixed, thereby destroying the overall liquid tension, avoiding excessive tension between liquids, too high liquid level, and the liquid at the bottom of the liquid surface cannot contact the gas, thereby increasing the contact time and contact area between the gas phase and the liquid phase, and improving the exchange efficiency of the gas-liquid two-phase.

[0057] In addition, since there is a certain gap between the arc-shaped disc 30 and the hole wall at the top of the tower plate 1 and the outer side of the arc-shaped protrusion 44, the outer shape of the arc-shaped protrusion 44 can reduce the resistance. At this time, the gas phase will blow up the liquid flowing around the baffle ring 10, and blow part of it into the arc-shaped disc 30. At the same time, the gas coming out of the square air outlet 47 just hits the bottom surface of the arc-shaped disc 30 and mixes with the liquid blown up around it, and at the same time enters the air inlet 31 at the center point from the outer edge of the arc-shaped disc 30. (The diameter of the air inlet 31 is larger than that of the screw 22 and the fixing hole 34, so the flow channel will not be affected by the screw 22 and the fixing hole 34. The liquid will rebound from the air inlet 31 to the collecting box 43, which will receive the liquid and gush out when the liquid reaches the highest liquid level. However, when gushing out, the narrow gap inside the wire disc 49 in the collecting box 43 will block the dirt, fiber and other impurities in the liquid and keep them in the collecting box 43. This reciprocating process can collect the impurities in the liquid and prevent excessive impurities from remaining on the surface of the float valve and affecting the use effect of the float valve.

[0058] When the float valve needs to be maintained, the staff first manually pulls the knob 21 upwards to pull the limit ring 53 at the bottom of the sliding frame 50 to the inner side of the retaining ring 10, then holds the top cover 20 above the sliding frame 50 with the palm of the hand, and directly pulls the top cover 20 upward with force. When pulling it out, the limit ring 53 is blocked by the retaining ring 10, and the limit ring 53 will rotate toward the middle through the limit plate 52 and the torsion spring shaft 51, and the gaps at both ends of the two limit rings 53 are closed, so that the limit ring 53 can be smoothly pulled out of the inner side of the retaining ring 10, and the float valve can be disassembled at this time. After disassembling the float valve; first single Clean the surface of the tower plate 1 alone, then twist the knob 21 above the top cover 20 on the top of the float valve counterclockwise to drive the screw 22 to rotate counterclockwise, so that the screw 22 is separated from the threaded sleeve at the center of the collection box 43. At this time, the staff can pull up the top cover 20. At this time, the arc-shaped disc 30 that was previously threadedly connected with the screw 22 and fixedly clamped with the collection box 43 can be pulled up and cleaned separately.
