Description

Technical Field

[0001] The utility model relates to the technical field of equipment for distillation towers, in particular to a liquid collector for distillation towers. Background Art

[0002] Distillation towers are prone to wall flow during operation. Generally, a redistributor is installed in the distillation tower to evenly distribute the wall flow throughout the tower. However, it is not easy to install a redistributor in a distillation tower with a smaller diameter, resulting in the wall flow in the distillation tower flowing along the tower wall to the bottom of the tower. This greatly reduces the amount of liquid reflux on the packing, thereby reducing the purity of the top product. Therefore, a liquid collector is used.

[0003] However, when the existing liquid collectors on the market are used, a flange is set at the top of the liquid collector to fix the liquid collector, which will cause part of the liquid to gather on the flange and then flow into the bottom of the tower along the gap between the flange of the liquid collector and the inner wall of the distillation tower, resulting in low distillation efficiency and the collected liquid cannot flow down evenly. Therefore, the present application proposes a liquid collector for a distillation tower to solve the above problems. Utility Model Content

[0004] In response to the above technical problems, the present invention provides a liquid collector for a distillation tower, which is characterized in that it includes a liquid collector body and a uniform distribution plate. The liquid collector body is composed of an outer ring part, a bottom plate and an inner ring part. The inner side of the bottom of the outer ring part is connected to the outer side of the bottom of the inner ring part through the bottom plate. The outer side of the top of the outer ring part is in contact with the inner wall of the distillation tower body. A plurality of fixed blocks provided on the outer side wall of the outer ring part are connected to the mounting assembly fixedly connected to the distillation tower body. The uniform distribution plate is provided at the upper opening of the inner ring part.

[0005] The mounting assembly consists of a mounting block, a spring and a limit block. The mounting block is fixedly connected to the inner wall of the distillation tower body. A fixing groove is provided on the mounting block and grooves are provided on the groove walls on both sides of the fixing groove. The limit block is slidably connected in the groove. A spring is provided between the limit block and the bottom of the groove.

[0006] The front end of the limit block is configured as an arc-shaped structure, and the limit block is adapted to the limit grooves provided on both sides of the fixed block.

[0007] A plurality of first overflow holes are arranged at intervals on the bottom plate, a plurality of second overflow holes are arranged at intervals on the inner ring portion, and a plurality of third overflow holes are arranged at intervals on the outer ring portion, and the height of the second overflow holes is lower than that of the third overflow holes.

[0008] Specifically, the through holes provided on the uniform distribution plate are evenly distributed.

[0009] Specifically, the lower end of the fixing block is configured to have a trapezoidal structure.

[0010] Specifically, mounting ears are respectively provided on both sides of the top surface of the outer ring portion for mounting the liquid collector body.

In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] Example 1

[0022] As shown in the figure, the liquid collector body 1 is composed of an outer ring part 11, a bottom plate 12 and an inner ring part 13. The inner side of the bottom of the outer ring part 11 is connected to the outer side of the bottom of the inner ring part 13 through the bottom plate 12, wherein mounting ears 6 are respectively provided on both sides of the top surface of the outer ring part 11, and a uniform distribution plate 2 is provided at the upper opening of the inner ring part 13. The through holes provided on the uniform distribution plate 2 are evenly distributed, and a plurality of first overflow holes 121 are arranged at intervals on the bottom plate 12, a plurality of second overflow holes 131 are arranged at intervals on the inner ring part 13, and a plurality of third overflow holes 111 are arranged at intervals on the outer ring part 11. The height of the second overflow hole 131 is lower than the height of the third overflow hole 111.

[0023] The outer side of the top of the outer ring portion 11 is fitted with the inner wall of the distillation tower body 3, and the multiple fixing blocks 4 provided on the outer side wall of the outer ring portion 11 are connected to the fixing groove 511 of the mounting block 51 fixedly connected to the distillation tower body 3. Grooves 512 are provided on both sides of the groove wall of the fixing groove 511 of the mounting block 51, and a limit block 53 is slidably connected in the groove 512. A spring 52 is provided between the limit block 53 and the bottom of the groove 512, and the front end of the limit block 53 is provided with an arc structure. The limit block 53 is adapted to the limit grooves 41 provided on both sides of the fixed block 4, as shown in FIG. Figure 3 The lower end of the fixed block 4 is arranged into a trapezoidal structure.

[0024] Example 2

[0025] When the liquid collector body 1 is installed in the distillation tower body 3 of the utility model, the liquid collector body 1 is lifted up by the lifting lug 6 of the liquid collector body 1 and placed in the distillation tower body 3, and the position of the liquid collector body 1 is adjusted so that the fixing block 4 fixedly installed on the liquid collector body 1 is inserted into the fixing groove 511 of the mounting block 51 on the inner wall of the tower body. Then, the liquid collector is lowered. Due to the weight of the liquid collector itself, the fixing block 4 will press the limiting blocks 52 on both sides of the fixing groove 511 downward, and the limiting block 53 with an arc-shaped end surface will press the spring 5 2 makes the limiting block 53 move into the groove, so that the fixing block 4 continues to move down to the bottom of the fixing groove 511. At this time, the limiting block 53 is compressed by the spring 52 and is stuck in the limiting grooves 41 on both sides of the fixing block 4, thus completing the installation. The operation is simple, and the outer wall of the top of the outer ring portion 11 of the liquid collector body 1 is in contact with the inner wall of the tower body. If the liquid collector needs to be removed, it can be removed by pulling it up with the lifting ear 6, which is convenient for disassembly. Compared with the current installation method of setting a flange, this method reduces the situation where liquid accumulates on the flange and then flows out from the gap between the flange and the tower body.

[0026] A plurality of overflow holes are arranged at intervals on the liquid collector body 1. When the liquid height is lower than the second overflow port 131, it flows downward from the first overflow hole 121 on the bottom plate 12. When the collected liquid reaches a height that allows it to flow out of the second overflow hole 131, it can flow out from the first overflow hole 121 on the bottom plate and evenly from the second overflow hole 131. When the liquid height is higher than the second overflow hole 131, the liquid can also flow out evenly from the third overflow hole 111 on the outer ring part 11. At this time, the liquid will also flow out from the opening of the inner ring part 13 to the uniform distribution plate 2, and the collected liquid will flow down evenly to avoid affecting the lower distillation operation.

[0027] The above shows and describes the basic principles, main features and advantages of the present invention. The various components mentioned in the present invention are common technologies in the existing field. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
