Description

Technical Field

[0001] This invention relates to the field of floating valve tray technology, specifically a guide floating valve tray for packed towers. Background Technology

[0002] Floating valve trays, as core components of gas-liquid mass transfer separation equipment in chemical, petroleum refining, distillation, and absorption processes, are widely used inside packed towers. Their working principle involves a liquid layer forming on the tray surface, with gas passing through contact elements and dispersing into bubbles, completing the mass and heat transfer process within the liquid layer. Gas-liquid contact states can be categorized as bubbling, honeycomb, foam, and jetting, with the foaming state exhibiting the highest mass transfer efficiency. Based on structural characteristics, they can be classified into sieve trays, floating valve trays, and bubble cap trays, among others.

[0003] Traditional float valves are mostly fixed installation structures, and the outlet angle and airflow direction cannot be flexibly adjusted according to the fluid velocity, material characteristics and process conditions inside the tower. In addition, float valves cannot guide and push the liquid. The internal ventilation structure design of conventional float valves is simple, the gas phase airflow distribution is uneven, and the valve plate is subjected to uneven force, which easily leads to problems such as valve plate jamming and inability to fully open and close, thus affecting the overall separation effect of the tower.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-8 A guide floating valve tray for a packed tower includes a tray body 1, a packed tower body 2 is provided around the tray body 1, and the tray body 1 is installed in the inner cavity of the packed tower body 2. The tray body 1 includes a tray assembly 11, and a float valve assembly 12 is installed in the inner cavity of the tray assembly 11. In the above structure, the float valve assembly 12 is mounted on the tray assembly 11, and the air outlet direction on the float valve assembly 12 can be adjusted to improve the flexibility of the device.

[0022] The tray assembly 11 includes a top plate 1101, a bottom plate 1102 is installed at the bottom of the top plate 1101, a top hole 1103 is opened at the top of the top plate 1101, a bottom hole 1104 is opened at the bottom of the bottom plate 1102, and a plurality of positioning grooves 1105 are opened at the top of the bottom plate 1102, the positioning grooves 1105 being located around the bottom hole 1104. In the above structure, the float valve assembly 12 can cooperate with the positioning groove 1105 through the setting of the positioning groove 1105. The positioning groove 1105 mainly restricts the rotation direction of the float valve assembly 12. When the limiting ball 1223 on the float valve assembly 12 is embedded in the positioning groove 1105, the float valve assembly 12 cannot rotate.

[0023] The float valve assembly 12 includes a valve body 1201, a mounting block 1202 is mounted on the top of the valve body 1201, a mounting shaft 1203 is mounted on the inner wall of the mounting block 1202, a valve plate 1204 is movably sleeved on the outer edge of the mounting shaft 1203, a guide plate 1205 is mounted on the end of the valve plate 1204 away from the mounting shaft 1203, side plates 1207 are mounted on both sides of the guide plate 1205, and guide holes 1206 and air outlet holes 1208 are respectively opened on the outer edges of the guide plate 1205 and the side plates 1207. An inner cylinder 1209 is installed in the inner cavity of the valve body 1201, a connecting cylinder 1211 is provided on the inner wall of the inner cylinder 1209, and an adjusting sleeve 1230 is provided on the inner wall of the connecting cylinder 1211.

[0024] In the above structure, gas enters the connecting cylinder 1211 through the adjusting sleeve 1230, and then enters the inner cylinder 1209. Subsequently, the gas pushes open the valve plate 1204, the guide plate 1205 and the side plate 1207, so that the gas is discharged through the guide plate 1205 and the vent 1208. When the gas is discharged from the guide plate 1205, it can push the liquid to move forward at an accelerated speed, and at the same time generate bubbles to mix fully with the liquid. When the gas is discharged through the vent 1208, the gas and the liquid come into contact and mix.

[0025] In a preferred embodiment: a connecting frame 1210 is installed on the inner wall of the inner cylinder 1209, a connecting screw 1214 is threadedly connected to the inner wall of the connecting frame 1210, a connecting post 1213 is installed at the bottom of the connecting screw 1214, a support frame 1212 is fixedly assembled on the outer wall of the connecting post 1213, and the support frame 1212 is installed on the connecting cylinder 1211.

[0026] In the above structure, by screwing the connecting screw 1214 into the connecting frame 1210, the support frame 1212 and the connecting cylinder 1211 can be connected to the inner cylinder 1209. At this time, the connecting cylinder 1211 and the support frame 1212 cannot fall downward, so that the support frame 1212 and the connecting cylinder 1211 are fixed.

[0027] In a preferred embodiment: a vertical hole 1215 is provided at the bottom of the connecting column 1213, and a rotating rod 1217 is slidably connected to the inner wall of the vertical hole 1215. A mounting housing 1220 is installed at the bottom of the rotating rod 1217. The mounting housing 1220 is installed on the adjusting sleeve 1230. Limiting rods 1222 are provided at both ends of the inner cavity of the mounting housing 1220. The limiting rods 1222 pass through the adjusting sleeve 1230 and the connecting cylinder 1211.

[0028] In the above structure, by setting the limiting rod 1222, when the limiting rod 1222 passes through the adjusting sleeve 1230 and the connecting sleeve 1211, the limiting rod 1222 is limited by the adjusting sleeve 1230, so that the limiting rod 1222 cannot move downward. When the limiting rod 1222 is in the retracted state, by rotating the mounting housing 1220, the connecting column 1213 and the connecting screw 1214 can be rotated by rotating the rotating rod 1217.

[0029] In a preferred embodiment: the inner wall of the connecting column 1213 is provided with a vertical groove 1216, and the outer edge of the rotating rod 1217 is fixedly fitted with a limiting groove 1218, which is slidably connected to the vertical groove 1216.

[0030] In the above structure, the vertical groove 1216 and the limiting groove 1218 can limit the position of the rotating rod 1217 and the connecting column 1213, so that the connecting column 1213 and the rotating rod 1217 can only be slidably connected. The rotating rod 1217 cannot rotate in the connecting column 1213. When the rotating rod 1217 rotates, it will drive the connecting column 1213 to rotate. Therefore, the connecting screw 1214 installed on the connecting column 1213 can be screwed into the connecting frame 1210.

[0031] In a preferred embodiment, a contact spring 1219 is movably sleeved on the outer edge of the rotating rod 1217, and the contact spring 1219 is located between the support frame 1212 and the mounting housing 1220.

[0032] In the above structure, the contact spring 1219 can support the mounting housing 1220, so that the limiting ball 1223 on the mounting housing 1220 can be located in the positioning groove 1105, so that the mounting housing 1220 cannot rotate. Only when the mounting housing 1220 moves upward can the limiting ball 1223 be separated from the positioning groove 1105.

[0033] In a preferred embodiment: a limiting ball 1223 is installed at one end of the limiting rod 1222, an adjusting bracket 1226 is movably connected to the end of the limiting rod 1222 away from the limiting ball 1223, a movable bracket 1227 is movably connected to the end of the adjusting bracket 1226 away from the limiting rod 1222, an adjusting screw 1228 is installed on the inner wall of the movable bracket 1227, the adjusting screw 1228 passes through the mounting housing 1220, and an adjusting nut 1229 is threadedly connected to the outer edge of the adjusting screw 1228.

[0034] In the above structure, rotating the adjusting nut 1229 drives the adjusting screw 1228 to move. The movement of the adjusting screw 1228 drives the moving bracket 1227 to move, gradually reducing the included angle between the two adjusting brackets 1226. At this time, the two limiting rods 1222 move towards the middle, and gradually the limiting rods 1222 and the limiting ball 1223 no longer penetrate the connecting cylinder 1211 and the adjusting sleeve 1230. At this time, the mounting housing 1220 can be rotated. Since the connecting screw 1214 is connected to the connecting bracket 1210, the top of the connecting cylinder 1211 will contact the connecting bracket 1210. When the mounting housing 1220 is rotated again, the connecting screw 1214 cannot be turned. Therefore, the valve body 1201 also rotates with the mounting housing 1220, so that the direction of the valve body 1201 can be adjusted.

[0035] In a preferred embodiment: a support plate 1224 is fixedly mounted on the outer edge of the limiting rod 1222, an inner sleeve 1221 is slidably connected to the outer edge of the limiting rod 1222, the inner sleeve 1221 is installed in the inner cavity of the mounting housing 1220, and a support spring 1225 is movably sleeved on the outer edge of the limiting rod 1222, the support spring 1225 is located between the inner sleeve 1221 and the support plate 1224.

[0036] In the above structure, the support spring 1225 can support the limiting rod 1222, so that the two adjusting brackets 1226 form an angle. By moving the adjusting screw 1228, the moving bracket 1227 can be moved. The movement of the moving bracket 1227 can push the adjusting bracket 1226 to both sides, so that the limiting rod 1222 can move outward, so that the limiting rod 1222 is always in a supported state.

[0037] In a preferred embodiment: a top sealing ring 1231 is fixedly mounted on the outer wall of the connecting cylinder 1211, the top sealing ring 1231 is in contact with the top plate 1101, the top plate 1101 is located between the valve body 1201 and the top sealing ring 1231, and a bottom sealing ring 1232 is installed on the outer wall of the connecting cylinder 1211, the bottom sealing ring 1232 is in contact with the bottom plate 1102.

[0038] In the above structure, the top sealing ring 1231 can contact the top plate 1101, so that the position of the connecting cylinder 1211 can be limited. When the inner cylinder 1209 is connected to the connecting cylinder 1211, the valve body 1201 just contacts the top plate 1101, so that there is no gap between the valve body 1201 and the top plate 1101. The top sealing ring 1231 also plays the role of sealing the bottom plate 1102, and the bottom sealing ring 1232 plays the role of sealing the bottom hole 1104.

[0039] In a preferred embodiment: the diameter of the top sealing ring 1231 is smaller than the diameter of the bottom hole 1104, the diameter of the top sealing ring 1231 is larger than the diameter of the top hole 1103, and the diameter of the bottom sealing ring 1232 is larger than the diameter of the bottom hole 1104.

[0040] In the above structure, the top sealing ring 1231 can enter between the top plate 1101 and the bottom plate 1102 through the bottom hole 1104, so that the top sealing ring 1231 can contact the top plate 1101 and seal the gap between the connecting cylinder 1211 and the top plate 1101. The bottom sealing ring 1232 seals the gap between the bottom plate 1102 and the connecting cylinder 1211.

[0041] In a preferred embodiment, the inner cylinder 1209 is located at the end away from the mounting block 1202, and the bottom of the inner cylinder 1209 is flush with the bottom of the valve body 1201.

[0042] In the above structure, by setting the inner cylinder 1209 at the end of the valve body 1201 away from the mounting block 1202, the gas in the inner cylinder 1209 can better blow up the valve plate 1204, which can effectively prevent the valve plate 1204 from getting stuck between the valve body 1201 and improve the stability of the device.

[0043] Working principle: In use, the support frame 1212, connecting column 1213, connecting screw 1214, and connecting cylinder 1211 are passed through the base plate 1102. Then, the connecting cylinder 1211 enters the inner cylinder 1209, aligning the connecting screw 1214 with the connecting frame 1210. By rotating the connecting cylinder 1211, the connecting screw 1214 is screwed into the connecting frame 1210. When the top of the connecting cylinder 1211 contacts the connecting frame 1210, the connecting cylinder 1211 cannot rotate. Then, the operator adjusts... The sleeve 1230 is inserted into the connecting sleeve 1211, and the rotating rod 1217 is simultaneously inserted into the connecting post 1213. At this time, the limiting rod 1222 is in a retracted state. The contact spring 1219 is installed on the rotating rod 1217. By rotating the adjusting nut 1229, the adjusting screw 1228 is pushed to move, causing the adjusting screw 1228 to drive the moving bracket 1227 to move, gradually causing the two adjusting brackets 1226 to move outward. The outward movement of the adjusting brackets 1226 can drive the limiting rod 1222 to move outward, gradually causing the limiting rod 1222 to move outward. The limiting ball 1223 corresponds to the positioning groove 1105. At this time, the mounting housing 1220 can be relieved of force. The spring force of the contact spring 1219 causes the mounting housing 1220 to move downwards, gradually allowing the limiting ball 1223 to enter the positioning groove 1105. When it is necessary to adjust the direction of the valve body 1201, the mounting housing 1220 is moved upwards, separating the limiting ball 1223 from the positioning groove 1105. Then, the adjusting nut 1229 is rotated in the opposite direction, causing the limiting rod 1222 to move inwards. The mounting housing 1220 is rotated, and gas enters the connecting cylinder 1211 through the adjusting sleeve 1230. The gas in the connecting cylinder 1211 then enters the inner cylinder 1209. The gas in the inner cylinder 1209 can push open the valve plate 1204, the guide plate 1205 and the side plate 1207. The gas is discharged through the guide hole 1206 on the guide plate 1205. At this time, the gas can push the liquid forward and guide the liquid. The gas discharged from the vent 1208 and the guide hole 1206 will come into contact with the liquid.
