Description

Technical Field

[0001] This invention relates to the field of hydrogen peroxide tail gas treatment technology, specifically to an integrated hydrogen peroxide tail gas adsorption-desorption-distillation recovery device. Background Technology

[0002] During the industrial production, storage, transportation, or downstream application of hydrogen peroxide, exhaust gases containing specific components are generated, which need to be recovered and treated using a recovery device.

[0003] In existing technologies, during the recovery and treatment of exhaust gas, the adsorption process needs to selectively retain the target components at normal temperature and pressure, while the desorption and regeneration process requires the introduction of heated gas and maintenance of a specific temperature. The process conditions of the two processes are different and cannot be carried out simultaneously in the same tower. When the adsorbent filled in a single tower reaches the adsorption saturation state, the feeding of hydrogen peroxide exhaust gas needs to be stopped. The adsorbent activity regeneration is completed through the heating desorption process, and the tower is cooled and depressurized to reset to the adsorption condition before the adsorption process can be restarted. This results in an intermittent period in the operation of the device, which affects the treatment efficiency of the exhaust gas. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, after the hydrogen peroxide tail gas is treated by the pretreatment mechanism, it enters the target switching tower through the outlet pipe, the main pipe and the opened third air valve. The target component is selectively adsorbed by the activated carbon adsorption layer in the tower. When the switching tower is saturated, its corresponding third air valve is closed and the third air valve of another switching tower is opened, realizing the adsorption process without downtime switching. The saturated switching tower is heated by the heating mechanism to desorb the target component. The alternating adsorption-desorption of multiple towers avoids the intermittent downtime of single tower operation, ensures the continuous operation efficiency of the device, and improves the operation stability and target component adsorption recovery rate of the device.

[0016] 2. In this invention, the third blower sends the gas through the first gas delivery pipe into the heater to be heated to the set temperature. Then, it enters the catalytic bed through the second gas delivery pipe for impurity purification. After passing through the fourth gas delivery pipe, the fourth blower, the third gas delivery pipe, and the opened fourth air valve, the gas is sent into the switching tower through the fifth gas delivery pipe to achieve target component desorption. The desorbed mixed gas enters the outer shell of the transition mechanism. After filtering out residual impurities through the internal filter, it is transported to the middle of the distillation tower through the second connecting pipe. This avoids impurities contaminating the target component and improves the desorption efficiency and desorption rate. At the same time, the filter performs secondary purification to remove impurities entrained in the desorbed gas, thereby improving the purity of the raw material entering the distillation tower.

[0017] 3. In this invention, after the hydrogen peroxide exhaust gas enters the treatment tower through the inlet pipe, the drive motor drives the rotating shaft and three sets of stirring blades to rotate synchronously, so that the exhaust gas can fully contact the filter material when passing through the three layers of filter plates, intercepting the dust and droplets entrained in the exhaust gas. Then the exhaust gas passes through the drying component fixed inside the treatment tower to remove the free moisture. The pre-treated clean exhaust gas is collected below the isolation plate and transported to the outlet pipe by the first connecting pipe and the first fan to enter the adsorption-desorption mechanism, so as to avoid the activated carbon adsorption layer from being deactivated due to moisture and blockage.

[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] Example 1: Refer to Figures 1-7As shown: An integrated hydrogen peroxide tail gas adsorption-desorption-distillation recovery device includes a distillation column 3. A transition mechanism 4 is installed on one side of the distillation column 3, and an adsorption-desorption mechanism 2 is installed at one end of the transition mechanism 4. The adsorption-desorption mechanism 2 includes a support frame 21. A switching column 22 is fixedly connected to the inner side of the support frame 21. Multiple switching columns 22 are arranged side by side on the support frame 21. The top of each of the multiple switching columns 22 is fixedly connected to a first connecting pipe 24. A first air valve 23 is installed on the outside of each of the multiple first connecting pipes 24. The other ends of the multiple first connecting pipes 24 are fixedly connected to a second connecting pipe 26. The bottom of each of the multiple switching columns 22 is fixedly connected to a feed pipe 210. A third air valve 211 is installed on the outside of each of the multiple feed pipes 210. The other ends of the multiple feed pipes 210 are fixedly connected to a third air valve 211. A main pipe 29 is fixedly connected to the main pipe 29. One end of the main pipe 29 is fixedly connected to an outlet pipe 212. The other end of the outlet pipe 212 is equipped with a pretreatment mechanism 1. An activated carbon adsorption layer 213 is fixedly connected inside the switching tower 22. A heating mechanism 5 is installed on one side of the switching tower 22. The heating mechanism 5 is used to input heating gas into the switching tower 22 to desorb the gas inside the switching tower 22.

A second air valve 25 is installed on the outside of each of the multiple fourth connecting pipes 214. The other end of the multiple fourth connecting pipes 214 is fixedly connected to a third connecting pipe 27. The other end of the third connecting pipe 27 is fixedly connected to a second fan 28.

[0022] In this embodiment, the pretreatment mechanism 1 is activated. After the hydrogen peroxide exhaust gas passes through the pretreatment mechanism 1 to remove dust, droplets, and metal ions, it passes through the exhaust pipe 212 and the main pipe 29. The third air valve 211 corresponding to the target switching tower 22 is opened, and the exhaust gas enters the switching tower 22 and passes through the activated carbon adsorption layer 213. The target components in the exhaust gas are adsorbed by the activated carbon adsorption layer 213. At this time, the first air valve 23 and the second air valve 25 corresponding to the switching tower 22 are in the closed state. When the activated carbon adsorption layer 213 of a certain switching tower 22 reaches adsorption saturation, its corresponding third air valve 211 is closed, and the third air valve corresponding to the other switching tower 22 is opened. 211, the exhaust gas is switched to a new switching tower 22 for continued adsorption, achieving continuous adsorption operation. The heating mechanism 5 is activated to input heating gas into the adsorption-saturated switching tower 22. At the same time, the first air valve 23 corresponding to the switching tower 22 is opened, and the target component on the activated carbon adsorption layer 213 is desorbed. The desorbed target component is transported to the transition mechanism 4 through the first connecting pipe 24 and the second connecting pipe 26, and finally enters the distillation tower 3 for purification. Multiple parallel switching towers 22, in conjunction with the first air valve 23, the second air valve 25 and the third air valve 211, realize the alternating switching of adsorption and desorption, avoid the downtime interval of single tower operation, and ensure the continuous operation of the device.

[0023] Example 2: Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, the heating mechanism 5 includes multiple fifth gas supply pipes 510. One end of each fifth gas supply pipe 510 is fixedly connected to the top side of the switching tower 22. A fourth air valve 55 is installed on the outside of each of the multiple fifth gas supply pipes 510. The other ends of the multiple fifth gas supply pipes 510 are all fixedly connected to a third gas supply pipe 56.

The other end of the fourth gas supply pipe 57 is fixedly connected to a catalytic bed 59. The other end of the catalytic bed 59 is fixedly connected to... The second gas supply pipe 54; the other end of the second gas supply pipe 54 is fixedly connected to the heater 51, the bottom end of the heater 51 is fixedly connected to the first gas supply pipe 52, and the other end of the first gas supply pipe 52 is fixedly connected to the third fan 53; the transition mechanism 4 includes an outer shell 41, a filter 42, and a second connecting pipe 43. One end of the second connecting pipe 43 is fixedly connected to the middle of the distillation column 3, and the other end of the second connecting pipe 43 is fixedly connected to one side of the outer shell 41. The other side of the outer shell 41 is fixedly connected to the other end of the second connecting pipe 26, and the second connecting pipe 43 is fixedly connected inside the outer shell 41.

[0024] In this embodiment, the gas is heated to a set temperature by the heater 51 through the first gas supply pipe 52 when the third fan 53 is working. The heated gas then enters the catalytic bed 59 through the second gas supply pipe 54 for purification to remove impurities. It is then transported through the fourth gas supply pipe 57, the fourth fan 58, and the third gas supply pipe 56. The fourth air valve 55 corresponding to the target switching tower 22 is opened, and the gas enters the switching tower 22 through the fifth gas supply pipe 510. The heated gas comes into contact with the activated carbon adsorption layer 213 in the switching tower 22, and the target component is desorbed. The desorbed mixed gas enters the outer shell 41 of the transition mechanism 4 through the opened first air valve 23, the first connecting pipe 24, and the second connecting pipe 26. After the residual impurities are filtered by the filter 42, it is transported to the interior of the distillation tower 3 through the second connecting pipe 43, thereby improving the desorption efficiency and the target component desorption rate.

[0025] Example 3: According to Figure 1 , Figure 2 and Figure 6As shown, the pretreatment mechanism 1 includes a treatment tower 14. An isolation plate 13 is fixedly connected inside the treatment tower 14. A rotating shaft 15 is rotatably connected to the middle of the isolation plate 13. A drive motor 17 is fixedly connected to one end of the rotating shaft 15. One side of the drive motor 17 is fixedly connected to the bottom end of the treatment tower 14. A drying assembly 18 is rotatably sleeved outside the rotating shaft 15. The drying assembly 18 is fixedly connected inside the treatment tower 14. An air inlet pipe 16 is fixedly connected to the top of the treatment tower 14. Three filter plates 110 are fixedly connected inside the treatment tower 14. The other end of the rotating shaft 15 rotates through the three filter plates 110 in sequence. Three sets of stirring blades 19 are fixedly connected to the outside of the rotating shaft 15 and are respectively arranged above the three filter plates 110. A first connecting pipe 12 is fixedly connected to one side of the treatment tower 14. A first fan 11 is fixedly connected to the other end of the first connecting pipe 12. The other end of the first fan 11 is fixedly connected to the air outlet pipe 212.

[0026] In this embodiment, hydrogen peroxide exhaust gas enters the treatment tower 14 through the inlet pipe 16. The drive motor 17 is started, and the drive motor 17 drives the rotating shaft 15 and the three sets of stirring blades 19 to rotate synchronously. The exhaust gas first flows through the three filter plates 110. The rotation of the stirring blades 19 makes the exhaust gas fully contact the filter plates 110, effectively removing dust and droplets entrained in the exhaust gas. Then the exhaust gas passes through the drying component 18, where free moisture is removed. The pre-treated exhaust gas is collected below the isolation plate 13 and transported to the outlet pipe 212 by the first connecting pipe 12 and the first fan 11. It then enters the adsorption-desorption mechanism 2 to remove impurities and moisture in the exhaust gas in advance, preventing the activated carbon adsorption layer 213 from getting damp and clogged, and extending its service life.

[0027] The operating method and working principle of this device are as follows: First, the hydrogen peroxide exhaust gas enters the treatment tower 14 through the inlet pipe 16. The drive motor 17 drives the rotating shaft 15 and three sets of stirring blades 19 to rotate synchronously, so that the exhaust gas can fully contact the three-layer filter plates 110 in the treatment tower 14 to intercept the dust and droplets entrained in the exhaust gas. Then, the exhaust gas passes through the drying component 18 to remove the free moisture and prevent the subsequent adsorbent from becoming damp and deactivated. The pretreated clean exhaust gas enters the first fan 11 through the first connecting pipe 12. Under the conveying action of the first fan 11, it passes through the outlet pipe 212. The main pipe 29 and the opened third air valve 211 enter the interior of a switching tower 22 in the adsorption-desorption mechanism 2, which is in an adsorption state. The activated carbon adsorption layer 213 in the switching tower 22 selectively adsorbs the target components in the exhaust gas. When the monitoring detects that the activated carbon adsorption layer 213 of the switching tower 22 has reached adsorption saturation, the control system closes the corresponding third air valve 211 and opens the third air valve 211 of another switching tower 22, so that the pretreated exhaust gas can be seamlessly switched to the new switching tower 22 to continue adsorption, realizing uninterrupted continuous operation of the adsorption process.

[0028] For the adsorption-saturated switching tower 22, the heating mechanism 5 is activated, and the third fan 53 sends the gas into the heater 51 through the first gas supply pipe 52 for heating. The heated gas enters the catalytic bed 59 through the second gas supply pipe 54 for purification to remove impurities, and then enters the adsorption-saturated switching tower 22 through the fifth gas supply pipe 510 via the fourth gas supply pipe 57, the fourth fan 58, the third gas supply pipe 56 and the opened fourth air valve 55. The desorbed gas comes into full contact with the activated carbon adsorption layer 213 in the switching tower 22, and the target components are desorbed. The desorbed mixed gas pushes open the first air valve 23 at the top of the switching tower 22 under pressure, and flows into the second connecting pipe 26 through the first connecting pipe 24.

[0029] The mixed gas enters the transition mechanism 4 through the second connecting pipe 26. Inside the outer shell 41, it is filtered by the filter 42 to remove any entrained residual impurities, preventing impurities from entering the subsequent distillation process and affecting the purity of the product. The purified mixed gas is then transported to the distillation column 3 through the second connecting pipe 43. The input mixed gas is then distilled and separated. The trace amounts of moisture and impurities in the mixed gas are removed through the in-column distillation process, and the target product is finally obtained.
