Description

Technical Field

[0001] The invention relates to the technical field of ceramic membrane filter treatment, and in particular to a treatment device for ammoximation of ceramic membrane tubes. Background Art

[0002] Caprolactam is an important organic chemical raw material, and the process of preparing cyclohexanone oxime by ammonia oxime is the core unit in the production of caprolactam. This process uses titanium silicon molecular sieve as a catalyst. Gas ammonia and hydrogen peroxide react under the action of the catalyst to produce hydroxylamine, which then reacts with cyclohexanone to produce cyclohexanone oxime. The crude oxime is separated from the catalyst by a membrane filtration system and then recovered by tert-butyl alcohol for recycling. The oxime water at the bottom of the tower is transported to toluene for extraction to separate the oxime water; the toluene oxime solution is then separated and refined by distillation to obtain the product cyclohexanone oxime.

[0003] Among them, the membrane filtration system often uses ceramic membrane filters. During the use of ceramic membrane filters, due to upstream raw materials, the ceramic membrane tube is easily blocked, causing the membrane permeation flux to gradually decrease, and even causing the membrane to be unable to continue to be used. Therefore, it is necessary to dismantle it for cleaning. The existing cleaning device uses a solution immersion cleaning method. Since it is a static treatment, it cannot restore the flux of the ceramic membrane tube.

[0004] Furthermore, the ceramic membrane tube needs to be tested for fracture and leakage after being cleaned by the cleaning device. Therefore, after each cleaning operation of the ceramic membrane tube is completed, it is necessary to manually transfer the tube to the testing device for fracture and leakage testing. This is not only time-consuming and labor-intensive, but also the existing testing device needs to be manually installed and tested one by one during the docking process of the ceramic membrane tube, which greatly reduces the processing efficiency of the ceramic membrane tube.

[0058] In the above solution, the structure of the blocking structure 8 is specifically as follows:

[0059] See attached Figure 4 As shown, the plugging structure 8 includes a fixed tube 81, an air injection valve 82, and a plugging seat 83; the fixed tube 81 is vertically arranged on the horizontal plate 61, and the top of the fixed tube 81 is connected to the hose 75, the fixed tube 81 is installed with the air injection valve 82, the bottom of the fixed tube 81 is connected with the plugging seat 83, and the plugging seat 83 is provided with an upper plugging cavity 731 that matches the size of the end of the ceramic membrane tube, and the upper plugging cavity 731 is correspondingly arranged with the lower plugging cavity 51 to achieve sealing of the two ends of the ceramic membrane tube;

[0060] To facilitate the disassembly, assembly and replacement of the plugging structure 8 , the middle portion of the fixed tube 81 is threadedly connected to the horizontal plate 61 , the top of the fixed tube 81 is connected to the hose 75 via a quick connector, and the bottom of the fixed tube 81 is threadedly connected to the plugging seat 83 .

[0061] In the above solution, the structure of the exhaust structure 9 is specifically as follows:

[0062] See attached Figure 5 As shown, the exhaust structure 9 includes an exhaust pipe 91, an insert pipe 92 and a pressure reducing valve 93; the exhaust pipe 91 is vertically arranged at the bottom of the processing box 2, and the top of the exhaust pipe 91 is connected with the insert pipe 92 which matches the size of the plug hole 52 and is used to connect to the plug hole 52, and the bottom end of the exhaust pipe 91 extends to the outside of the processing box 2 and is installed with a pressure reducing valve 93;

[0063] In consideration of the disassembly, assembly and replacement of the exhaust structure 9 , the middle portion of the exhaust pipe 91 is threadedly connected to the processing box 2 , and the top end of the exhaust pipe 91 is threadedly connected to the insert pipe 92 .

[0064] In the specific implementation process of this device, refer to the attached Figure 7 -Attached Fig. 9 As shown, the following operation process is included:

[0065] 1) First, the telescopic cylinder 1 4 operates so that the placement platform 5 is located on the upper part of the processing box 2. At this time, the ceramic membrane tube is loaded and vertically inserted into the lower blocking cavity 51 on the placement platform 5 so that the position of the ceramic membrane tube is fixed;

[0066] 2) Then, the telescopic cylinder 14 operates so that the placement platform 5 is in the middle of the processing box 2. At the same time, the vibration motor 14 operates to make the processing box 2 vibrate at a high frequency, so that the solution inside the processing box 2 is fully in contact with the ceramic membrane tube and the surface of the ceramic membrane tube is impact-cleaned, so that the blockage on the ceramic membrane tube is fully dissolved. After the blockage is dissolved, it is discharged from the jack 52 on the placement platform 5 or the top of the ceramic membrane tube;

[0067] 3) Subsequently, the telescopic cylinder 2 6 operates to move the blocking seat 83 downward until the upper blocking cavity 731 seals the top of the ceramic membrane tube. At the same time, the telescopic cylinder 1 4 operates to place the placement platform 5 at the bottom of the processing box 2. At this time, the bottom surface of the placement platform 5 is close to the bottom of the processing box 2, and the insertion tube 92 is inserted into the insertion hole 52 on the placement platform 5. At this time, the bottom and top of the ceramic membrane tube are both in a sealed state;

[0068] 4) After a while, the pressure reducing valve 93 opens to discharge the solution in the ceramic membrane tube;

[0069] 5) Next, one of the pressure reducing valves 93 is opened, and the opening of the pressure reducing valve 93 is adaptively adjusted, and the corresponding gas injection valve 82 is opened, and the other pressure reducing valves 93 and gas injection valves 82 are closed. At this time, the air pump 71 operates to inject gas into the ceramic membrane tube along the open blocking seat 83. At this time, the gas passes through the side wall of the ceramic membrane tube into the solution to form bubbles. The average size and number of bubbles are used to judge whether the ceramic membrane tube has hidden damage. If there are obviously large bubbles, it proves that the ceramic membrane tube is damaged and cannot be used;

[0070] 6) Thereafter, repeat step 5) to complete the inspection of all ceramic membrane tubes;

[0071] 7) Finally, the inspection of the ceramic membrane tube is completed, and the telescopic cylinder 4 operates so that the placement platform 5 is located on the upper part of the processing box 2. At this time, the ceramic membrane tube is unloaded.

[0072] It is worth noting that, considering the ingenuity and functionality of the device, Fig.10 As shown, before the inspection operation of the ceramic membrane tube begins, for step 3), when the sealing structure 8 moves to the inside of the processing box 2 and seals the top of the ceramic membrane tube, at this time, the telescopic cylinder 2 6 and the retracted cylinder 1 are stationary for a period of time. During this period, the gas injection structure 7 starts to operate and injects gas into the sealing structure 8. The generated gas will blow out the blockage inside the ceramic membrane tube. At the same time, the gas will agitate the solution in the processing box 2, thereby increasing the collision effect between the solution and the ceramic membrane tube, accelerating and improving the cleaning ability. For a period of time, the telescopic cylinder 2 6 and the retracted cylinder 1 operate simultaneously, so that the placement platform 5 is at the bottom of the processing box 2.
