Description

Technical Field

[0001] This utility model relates to the field of falling film absorbers, and in particular to a uniformly coated graphite falling film absorber. Background Technology

[0002] Graphite falling film absorbers are mainly used in the reaction and absorption of gases and liquids. They are a very important piece of chemical equipment, primarily used in the production of acids such as hydrochloric acid. Their absorption and cooling sections are classified into two types according to their structure: tubular and circular perforated. Their structural classification is the same as that of tubular and circular perforated graphite heat exchangers. The heat exchange material of the circular perforated graphite falling film absorber is a porous cylindrical graphite block, while the heat exchange material of the tubular graphite falling film absorber is a graphite heat exchange tube bundle.

[0003] In the existing technology, the internal structure of traditional graphite falling film absorbers is mostly fixed. This setting will cause uneven adhesion of liquid or gas during use, thereby reducing the cooling absorption efficiency of the graphite falling film absorber and reducing its practicality.

[0024] Reference Figures 1 to 6 The present invention provides a uniformly coated graphite falling film absorber, comprising an absorption cylinder 1, an upper end cap 2, and a lower end cap 3. The upper end cap 2 and the lower end cap 3 are respectively disposed at the top and bottom ends of the absorption cylinder 1. An air inlet pipe 4 and a liquid inlet pipe 5 are connected to the outer surface of the upper end cap 2, and an air outlet pipe 6 and a liquid outlet pipe 7 are connected to the outer surface of the lower end cap 3.

[0025] To facilitate the assembly and disassembly of the upper end cap 2 and the lower end cap 3, connecting pipes 15 are fixedly installed at the top and bottom of the absorption cylinder 1. A sealing sleeve 16 is fitted on the outer surface of the connecting pipe 15. Connecting grooves for insertion into the corresponding connecting pipes 15 are opened on the inner walls of the upper end cap 2 and the lower end cap 3. The sealing sleeve 16 is slidably connected to the inner wall of the connecting groove.

The fixing bolts 20 penetrate the outer surface of the fixing sleeves 18 and are inserted into the outer surface of the absorption cylinder 1.

[0026] By configuring an absorption cylinder 1, an upper end cap 2, a lower end cap 3, an air inlet pipe 4, a liquid inlet pipe 5, an air outlet pipe 6, a liquid outlet pipe 7, a support frame 8, a graphite condenser 9, a connecting rod 10, a motor 11, a rotating rod 12, a locking block 13, a dispersion plate 14, a connecting pipe 15, a sealing sleeve 16, a positioning block 17, a fixing sleeve 18, a slider 19, and a fixing bolt 20, the function of uniformly coating liquid or gas inside the graphite falling film absorber is achieved. The dispersion plate 14 disperses the liquid and gas, and the motor 11 and the rotating rod 12 drive the dispersion plate 14 and the graphite condenser 9 to rotate, so that the liquid or gas is uniformly coated onto the graphite condenser 9, thereby ensuring the absorption efficiency of the graphite falling film absorber and improving its practicality.

[0027] The absorption cylinder 1 is provided with a fixing assembly, which includes a fixing frame 21. The fixing frame 21 is located outside the absorption cylinder 1. Threaded rods 22 are threadedly connected to both side walls of the fixing frame 21. Both threaded rods 22 penetrate the side walls of the fixing frame 21. A turntable 23 is fixedly installed at the end of the threaded rod 22 away from the fixing frame 21. A clamping block 24 is rotatably connected to the end of the threaded rod 22 away from the turntable 23. A sliding rod 25 is fixedly installed at the bottom end of the side wall of the clamping block 24. The two sliding rods 25 penetrate the inner walls of both sides of the fixing frame 21. A rubber pad 26 is fixedly installed on the arc-shaped inner wall of the clamping block 24. A positioning plate 27 is fixedly installed on the outer surface of the absorption cylinder 1. The upper surface of the clamping block 24 is in contact with the lower surface of the positioning plate 27.

[0028] By setting up a fixing frame 21, threaded rod 22, turntable 23, clamping block 24, sliding rod 25, rubber pad 26 and positioning plate 27, the function of quickly suspending and fixing the graphite falling film absorber is realized. By using two clamping blocks 24 that can approach each other to clamp and support the graphite falling film absorber, the graphite falling film absorber can be quickly suspended and fixed, which is quick and convenient, saves time and effort, and improves the convenience of the graphite falling film absorber.

[0029] Working principle: When assembling the graphite falling film absorber, first slide the graphite condenser 9 from the top of the absorber cylinder 1 into the interior of the absorber cylinder 1, so that the graphite condenser 9 contacts the support frame 8, and the connecting rod 10 passes through the support frame 8. Then, place the two sealing sleeves 16 close to the connecting pipes 15 at both ends of the absorber cylinder 1, move the sealing sleeves 16, and put the two sealing sleeves 16 onto the outer surfaces of the two connecting pipes 15, so that the positioning block 17 passes through the sealing sleeve 16. Next, place the upper end cap 2 and the lower end cap 3 close to the top and bottom ends of the absorber cylinder 1, so that the two fixing sleeves 18 are aligned with the absorber cylinder 1, the slider 19 is aligned with the slide groove, and the connecting pipe 15 is aligned with the connecting groove. Move the upper end cap 2 and the lower end cap 3 close to the top and bottom ends of the absorber cylinder 1, so that the two fixing sleeves 18 are aligned with the absorber cylinder 1, the slider 19 is aligned with the slide groove, and the connecting pipe 15 is aligned with the connecting groove. The upper end cap 2 and the lower end cap 3 slide on the outer surface of the two connecting pipes 15 through the connecting groove. The fixing sleeve 18 slides on the outer surface of the absorption cylinder 1, and the slider 19 slides inside the sliding groove. When the fixing sleeve 18 is completely fitted onto the outer surface of the absorption cylinder 1, the upper end cap 2 and the lower end cap 3 are connected to the absorption cylinder 1, thereby fixing the lower end cap 3 to the absorption cylinder 1. During this process, the rotating rod 12 is inserted into the top of the graphite condenser 9, the locking block 13 slides into the inside of the locking groove, and then the fixing bolt 20 is turned so that the fixing bolt 20 penetrates the outer wall of the fixing sleeve 18 and is inserted into the outer wall of the absorption cylinder 1, thereby fixing the fixing sleeve 18 and completing the assembly of the graphite falling film absorber.

[0030] When fixing the graphite falling film absorber, first rotate the two turntables 23, which will drive the two threaded rods 22 to rotate, so that both threaded rods 22 extend towards the fixing frame 21. During the rotation of the threaded rods 22, the clamping blocks 24 will move. Under the action of the sliding rod 25, the two clamping blocks 24 will move closer to each other. When the two clamping blocks 24 reach a suitable distance, place the graphite falling film absorber between the two clamping blocks 24, so that the two clamping blocks 24 are below the positioning plate 27. Rotate the two turntables 23 again, so that the two clamping blocks 24 move closer to the graphite falling film absorber. When the rubber pads 26 on the arc-shaped inner wall of the two clamping blocks 24 contact the graphite falling film absorber, the graphite falling film absorber is clamped and supported, thereby fixing and suspending the graphite falling film absorber.

[0031] When using the graphite falling film absorber, gas and absorbent are introduced into the absorber cylinder 1 through the air inlet pipe 4 and the liquid inlet pipe 5, respectively. At the same time, the motor 11 is started. When the motor 11 runs, it drives the rotating rod 12 to rotate. During the rotation of the rotating rod 12, it drives the locking block 13 and the dispersion plate 14 to rotate. During the rotation of the locking block 13, it drives the graphite condenser 9 to rotate through the locking groove. The above work together to ensure that the gas and absorbent are both adhered to the outer surface of the graphite condenser 9. After the gas and absorbent pass through the graphite condenser 9, the absorption is completed. Then, the absorbed gas is discharged from the graphite falling film absorber through the air outlet pipe 6, and the absorbed absorbent is discharged from the graphite falling film absorber through the liquid outlet pipe 7, thus completing the absorption work.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
