Description

Technical Field

[0001] This invention relates to the field of pharmaceutical waste gas treatment technology, specifically to an integrated waste gas treatment device and method for pharmaceutical applications. Background Technology

[0002] The waste gas generated during pharmaceutical production has a complex composition, typically containing various pollutants such as volatile organic compounds, acidic gases, and particulate matter. How to efficiently and safely treat pharmaceutical waste gas has become a key technical problem that urgently needs to be solved in this field.

[0003] Currently, the pharmaceutical industry primarily employs staged treatment processes for waste gas. For particulate matter in the waste gas, the mainstream solution is to use bag filters or dry filters for interception. However, these methods maintain a constant filter mesh size, making it impossible to adjust in real time when the particle size in the pharmaceutical waste gas changes, thus affecting filtration efficiency. Furthermore, when the concentration of particulate matter in the waste gas is too high, directly introducing it into an oxidation furnace for combustion and oxidation can easily lead to explosions, posing a significant safety hazard.

[0017] 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.

[0018] Example: Figures 1-11 As shown, the present invention provides a technical solution for an integrated waste gas treatment device for pharmaceutical applications. This integrated waste gas treatment device includes an oxidizer 1, a heat storage body 11 inside the oxidizer 1, a rotary valve 2 installed at the bottom of the oxidizer 1, the rotary valve 2 having an inlet channel 21 and an exhaust channel 22, the inlet channel 21 being connected to a buffer chamber 3, a dilution channel 4 at the bottom of the buffer chamber 3, a pipe diameter adjustment component 5 fixedly installed on the dilution channel 4, a gas storage tank 41 fixedly installed at the end of the dilution channel 4, an air inlet 31 on the buffer chamber 3, the air inlet 31 being fixedly connected to a filter assembly 6, the filter assembly 6 including a mounting housing 61 and a filter screen 66, interfaces 6101 on both ends of the mounting housing 61, and pressure detection components 6102 on the inner wall of the interfaces 6101.

[0019] Before the pharmaceutical waste gas enters the treatment equipment, the composition of the waste gas is detected. The appropriate mesh size of the filter screen 66 is automatically selected according to the size of the particulate matter in the waste gas to avoid poor filtration effect or filter screen blockage. At the same time, pressure detection devices 6102 are set before and after the filter component 6. The pressure difference before and after can reflect the blockage of the filter screen 66, which makes it easy to determine the replacement cycle of the filter screen 66, improve the overall waste gas treatment effect and maintenance efficiency of the equipment.

[0020] After filtration, the concentration of pharmaceutical waste gas is monitored. The opening 14 of the pipe diameter regulating component 5 is adjusted in real time according to the concentration of pharmaceutical waste gas. Low-concentration fresh air is introduced into the buffer chamber 3 through the dilution channel 4 to dilute the pharmaceutical waste gas, preventing high-concentration waste gas from exploding during oxidation and ensuring the safety of waste gas treatment.

[0021] After undergoing pretreatment, the pharmaceutical waste gas enters the rotary valve 2 through the inlet channel 21. The rotation of the rotary shaft 23 continuously distributes the pharmaceutical waste gas to different heat storage bodies 11 for preheating, and the gas after oxidation and combustion passes through the heat storage body 11 and is discharged. During the discharge process, the high-temperature gas transfers heat to the heat storage body 11, thereby improving the heat recovery efficiency.

[0022] The mounting housing 61 has a notch 6103 on its side wall and a rotating motor 6104 is mounted on the top of the mounting housing 61. The filter assembly 6 also includes a movable baffle 62, which is located on the side wall of the mounting housing 61 and blocks the notch 6103. A collection groove 6201 is provided on the movable baffle 62. A rotating shaft 63 is provided inside the mounting housing 61 and is connected to the output end of the rotating motor 6104. A partition 6301 is provided around the side wall of the rotating shaft 63, and a sealing strip 6302 is provided at the edge of the partition 6301.

[0023] A connecting port 64 is provided on the upper ring of the rotating shaft 63. Slots 6401 are provided on both side walls of the connecting port 64. A locking spring 6402 is installed at the bottom of the slot 6401. A pin 65 is provided inside the slot 6401, with its bottom fixedly connected to the locking spring 6402. A first inclined surface 6501 is provided on the pin 65 facing the connecting port 64, and a second inclined surface 6502 is provided on the top of the pin 65. A return spring 6403 is fixedly installed on the rear wall of the connecting port 64, and is fixedly connected to a return plate 6404. A filter screen 66 is installed between two partitions 6301. The filter assembly 6 includes an installation sleeve 6601 and a filter element 6602. The side wall of the installation sleeve 6601 is provided with a connecting block 6603. Both sides of the connecting block 6603 are provided with connecting grooves 6604. The filter element 6602 with a mesh size matching can not only improve the filtration effect of exhaust gas, but also slow down the clogging speed of the filter element 6602 and improve its service life. Pressure detection elements 6102 are provided in the front and rear interfaces 6101 of the filter assembly 6. The clogging status of the filter element 6602 is judged according to the pressure difference before and after the exhaust gas, which makes it easier for the staff to judge the replacement cycle of the filter element 6602, thereby improving the efficiency of subsequent maintenance.

[0024] Press the filter screen 66 downwards. Under pressure, the pin 65 is pressed back into the slot 6401 along the second inclined surface 6502. The connecting block 6603, no longer restrained by the pin 65, is ejected by the return spring 6403, completing the disassembly of the filter screen 66. To install a new filter screen 66, simply insert the connecting block 6603 into the connecting port 64. The pin 65 is pressed into the slot 6401 along the first inclined surface 6501 until the connecting groove 6604 connects with the slot 6401. The pin 65 then pops out again, completing the fixing of the new filter screen 66.

[0025] In addition, during the process of switching the filter screen 66 by rotating shaft 63, the edge sealing strip 6302 continuously scrapes away the impurities attached to the inner wall of the mounting housing 61. Finally, these impurities are collected by the collection groove 6201 and removed when the movable baffle 62 is removed, thus completing the self-cleaning of the filter assembly 6.

[0026] An adjustment motor 32 is installed at the bottom of the buffer chamber 3, and an adjustment wheel 3201 is installed at the output end of the adjustment motor 32.

[0027] The pipe diameter adjusting component 5 includes a rotating seat 51 and a fixed seat 52. An adjusting plate 53 is arranged circumferentially between the rotating seat 51 and the fixed seat 52. Both the rotating seat 51 and the fixed seat 52 have through holes 54 in the middle. The bottom of the rotating seat 51 is uniformly provided with arc-shaped grooves 5101, and the side wall of the rotating seat 51 is provided with retaining teeth 5102. The top of the fixed seat 52 is uniformly provided with straight grooves 5201. Both ends of the adjusting plate 53 are provided with limit posts 5301. One limit post 5301 is embedded in the arc-shaped groove 5101, and the other limit post 5301 is embedded in the straight groove 5201. The adjusting wheel 3201 meshes with the retaining teeth 5102. The concentration is detected before the exhaust gas enters the buffer chamber 3. When the concentration is too high, the adjusting motor 32 is started. Motor 32 drives the adjusting wheel 3201 to rotate, and the adjusting wheel 3201 meshes with the locking tooth 5102. Therefore, the adjusting motor 32 can drive the rotating seat 51 to rotate. When the rotating seat 51 rotates, the limiting posts 5301 on both sides of the adjusting plate 53 move in the straight groove 5201 and the arc groove 5101 respectively. This allows the adjusting plate 53 to move along the direction of the straight groove 5201, opening the through hole 54 and allowing the low-concentration fresh air in the gas storage tank 41 to enter the buffer chamber 3 and mix with the high-concentration exhaust gas to complete the dilution, thereby reducing the exhaust gas concentration. The size of the through hole 54 is adjusted in real time according to the concentration entering the buffer chamber 3, thereby ensuring that the exhaust gas concentration entering the oxidation furnace 1 is basically consistent and maintaining the stability of the combustion temperature in the combustion chamber 13.

[0028] The oxidizing furnace 1 is uniformly surrounded by heat insulation plates 12, and the heat storage body 11 is installed between the two heat insulation plates 12. The top of the heat insulation plate 12 is provided with a combustion chamber 13, and the bottom of the oxidizing furnace 1 is provided with an opening 14.

[0029] A rotating shaft 23 is provided inside the rotating valve 2. An air supply channel 2301 is provided inside the rotating shaft 23. An inlet 2302 is provided at the connection between the rotating shaft 23 and the air inlet channel 21. A distribution chamber 24 is provided at the top of the rotating shaft 23. The distribution chamber 24 is connected to the opening 14. The distribution chamber 24 includes a preheating zone 2401 and an air outlet zone 2402. A sealing plate 25 is provided between the air inlet channel 21 and the exhaust channel 22. The air supply channel 2301 is connected to the preheating zone 2401, and the exhaust channel 22 is connected to the air outlet zone 2402.

[0030] This application provides a waste gas treatment method for an integrated waste gas treatment device used in pharmaceutical manufacturing, the steps of which are as follows: S1: Introduce pharmaceutical exhaust gas into the filter assembly 6, and switch the filter screen 66 with the appropriate mesh size according to the particle size in the pharmaceutical exhaust gas. S2: By comparing the pressure difference between the two ports 6101 on both sides of the filter assembly 6 using the pressure detection element 6102, it can be determined whether the filter screen 66 is blocked, which makes it easier to determine the replacement cycle of the filter screen 66. S3: After filtration, the concentration of pharmaceutical waste gas is detected. When the concentration is too high, the dilution channel 4 is opened through the pipe diameter adjustment component 5 to dilute the high concentration of pharmaceutical waste gas in the buffer chamber 3. S4: The pretreated pharmaceutical waste gas is distributed in the oxidation furnace 1 through the rotary valve 2 for oxidation and decomposition, and finally discharged as pollution-free gas.

[0031] Working principle of the invention: Before treating pharmaceutical waste gas, the main components and particle size of the waste gas are detected. Based on the components, a suitable alkaline washing method is selected to reduce the corrosiveness of the waste gas. Then, the gas is introduced into the filter assembly 6 through interface 6101. The filter assembly 6 contains filter elements 6602 with different mesh sizes. The appropriate filter element 6602 is selected based on the previously detected particle size and connected to interface 6101. After prolonged use, the filter screen 66 needs to be replaced. First, the filter screen 66 to be replaced is moved to the notch 6103 by rotating the motor 6104. Then, the movable baffle 62 is removed. Simply press the filter screen 66 downwards; under pressure, the pin 65 is pressed back into the slot 6401 along the second inclined surface 6502. When the connecting block 6603 loses the limit of the pin 65, it is ejected under the push of the return spring 6403, completing the disassembly of the filter screen 66. To install the new filter screen 66, simply insert the connecting block 6603 into the connecting port 64, and the pin 65 is pressed into the slot 6401 along the first inclined surface 6501 until the connecting groove 6604 is connected to the slot 6401. The pin 65 then pops out again to fix the new filter screen 66. In addition, during the process of switching the filter screen 66 by rotating the shaft 63, the edge sealing strip 6302 continuously scrapes away the impurities attached to the inner wall of the mounting housing 61. Finally, these impurities are collected by the collection groove 6201 and removed when the movable baffle 62 is removed, completing the self-cleaning of the filter assembly 6.

[0032] After the exhaust gas is filtered, a concentration test is required to prevent high-concentration exhaust gas from exploding during combustion oxidation. When the concentration is detected to be too high, the regulating motor 32 is activated, which drives the regulating wheel 3201 to rotate. The regulating wheel 3201 engages with the locking tooth 5102, so the regulating motor 32 can drive the rotating seat 51 to rotate. When the rotating seat 51 rotates, the limiting posts 5301 on both sides of the regulating plate 53 move in the straight groove 5201 and the arc groove 5101 respectively. This allows the regulating plate 53 to move along the direction of the straight groove 5201, opening the through hole 54 and allowing the low-concentration fresh air in the gas storage tank 41 to enter the buffer chamber 3 and mix with the high-concentration exhaust gas to dilute it, thereby reducing the exhaust gas concentration. The size of the through hole 54 is adjusted in real time according to the concentration entering the buffer chamber 3 to ensure that the concentration of exhaust gas entering the oxidizer 1 is basically consistent and to maintain the stability of the combustion temperature in the combustion chamber 13.

[0033] After the preceding pretreatment, the pharmaceutical waste gas enters the rotary valve 2 through the inlet channel 21. The waste gas then passes through the inlet 2302 and the gas delivery channel 2301 into the preheating zone 2401 of the distribution chamber 24. Subsequently, as the rotating shaft 23 rotates, the waste gas is passed into different heat storage bodies 11 for preheating. Afterward, it enters the combustion chamber 13 at the top of the oxidizer 1 for complete combustion to generate carbon dioxide and water. The purified gas passes through the heat storage body 11 and enters the outlet zone 2402 in the distribution chamber 24. During the process of passing through the heat storage body 11, the high-temperature purified gas transfers heat to the relatively low-temperature heat storage body 11, achieving full heat recovery and improving energy utilization. The outlet zone 2402 is connected to the exhaust channel 22, which is set to negative pressure. Finally, the purified gas is spontaneously discharged through the exhaust channel 22 due to the pressure difference, completing the treatment of the pharmaceutical waste gas.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.

S2: By comparing the pressure difference between the two ports (6101) of the filter assembly (6) with the pressure detection device (6102), it can be determined whether the filter screen (66) is blocked, so as to determine the replacement cycle of the filter screen (66). S3: After filtration, the concentration of pharmaceutical waste gas is detected. When the concentration is too high, the dilution channel (4) is opened through the pipe diameter adjustment component (5) to dilute the high concentration of pharmaceutical waste gas in the buffer chamber (3). S4: The pretreated pharmaceutical waste gas is distributed in the oxidation furnace (1) through the rotary valve (2) for oxidation and decomposition, and finally discharged as pollution-free gas.
