Description

Technical Field

[0001] This invention relates to the field of chemical waste gas purification equipment technology, specifically a waste gas purification structure for chemical machinery with filtration function. Background Technology

[0002] Chemical waste gas is usually purified using biofilm technology. Before treatment, the waste gas needs to be pressurized and prehumidified before being discharged into the filter tower, so that it can come into contact with the biofilm and be absorbed. However, the residence time of the waste gas in the existing pressurized prehumidification step is relatively short, resulting in poor prehumidification effect, which affects the subsequent biofilm absorption effect.

[0003] The chemical waste gas transported inside the waste gas purification structure contains large particulate matter, which accumulates over time, affecting the normal operation of the device. Furthermore, the filtration system inside the waste gas purification structure makes it difficult to disassemble and clean, thus affecting the waste gas purification efficiency. To address these issues, this invention proposes a waste gas purification structure for chemical machinery with filtration function. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a waste gas purification structure for chemical machinery with filtration function, including a base plate, and further comprising:

[0005] The main structure has internal installation space.

[0006] The filtration system provides the filtration function.

[0007] The medicine tank mechanism continuously supplies the spray system;

[0008] A molecular filter membrane is fixedly connected to the inner wall of the tank, a flue pipe is fixedly connected to the bottom of the tank, and a medicine barrel is fixedly connected to the outer wall of the tank.

[0009] Preferably, the main structure includes:

[0010] The support assembly is fixedly connected to the outer wall of the main structure via support members.

[0011] The support components include a support frame that is fixedly connected to the outer wall of the base plate;

[0012] Safety components are fixedly connected to the outer wall of the support assembly via safety parts;

[0013] Safety components include a safety platform fixedly connected to the outer wall of the tank, a safety ladder fixedly connected to the outer wall of the tank, a smoke exhaust pipe connected through the top of the tank, the end of the smoke exhaust pipe away from the tank being fixedly connected to the bottom of the discharge pipe, and a sewage outlet opened on the outer wall of the tank.

[0014] Preferably, the filtration mechanism includes:

[0015] The filter assembly is fixedly connected to the inner wall of the main body through filter elements;

[0016] The filter element includes filter cotton that is fixedly connected to the tank body;

[0017] The flue assembly is fixedly connected to the inner wall of the filter assembly via flue components;

[0018] The flue components include flue pipes that are fixedly connected to the inner wall of the base plate.

[0019] Preferably, the medicine barrel mechanism includes:

[0020] Medicine barrel assembly, the medicine barrel assembly is fixedly connected to the outer wall of the main body;

[0021] Piping assembly, which is fixedly connected to the inner wall of the medicine barrel assembly.

[0022] Preferably, the support assembly includes a discharge pipe fixedly connected to the outer wall of the support frame, and a feed pipe fixedly connected to the outer wall of the tank.

[0023] Preferably, the safety component includes a sludge storage platform fixedly connected to the inner wall of the tank, a filter inclined plate fixedly connected to the inner wall of the tank, the outer wall of the filter inclined plate fixedly connected to the outer wall of the sludge storage platform, and a water storage space provided at the bottom of the filter inclined plate.

[0024] Preferably, the filter assembly includes several filter cottons fixedly connected to the inner wall of the tank, a partition plate fixedly connected to the inner wall of the tank, an annular tube fixedly connected to the inner wall of the tank, and several electronic nozzles fixedly connected to the outer wall of the annular tube. When the equipment is turned on, the exhaust gas enters the equipment through the feed pipe. When the exhaust gas enters the equipment, it moves upward through the molecular filter membrane and filter cotton. When excess moisture flows from the filter cotton into the molecular filter membrane, the moisture penetrates the molecular filter membrane and remains on its surface. As the exhaust gas moves upward through the molecular filter membrane, the PM2.5 in the exhaust gas is filtered by the molecular filter. The membrane acts as an external barrier. Due to the layered filtration of the molecular filtration membrane, PM2.5 cannot penetrate it to achieve the function of filtering dust. When water molecules penetrate the molecular filtration membrane and move downwards, they carry the PM2.5 trapped in the membrane outwards, forming water droplets containing grit on the surface of the membrane. This prevents the molecular filtration membrane from becoming clogged with PM2.5 after prolonged use, which would cause the filtration system to malfunction. This extends the service life of the molecular filtration membrane, prolongs the frequency of membrane replacement, and avoids frequent membrane replacements affecting equipment operation.

[0025] Preferably, the flue assembly includes a rotating shaft rotatably connected to the inner wall of the flue pipe. Several fan blades are fixedly connected to the outer wall of the rotating shaft, and the fan blades are in close contact with the inner wall of the flue pipe. Several smoke outlets are provided on the outer wall of the flue pipe. Several scrapers are fixedly connected to the end of the rotating shaft away from the fan blades, and the scrapers are in close contact with the outer wall of the molecular filter membrane. Utilizing the force of the aforementioned exhaust gas movement, when the exhaust gas enters the flue pipe through the feed pipe, it is discharged outwards through the smoke outlets in the flue pipe. When the exhaust gas passes through the fan blades, it drives the fan blades to rotate and discharges from the smoke outlets, causing the rotating shaft to rotate. When the rotating shaft rotates, it drives the scrapers fixedly connected to the upper end to rotate, scraping the surface of the molecular filter membrane. This prevents small particles from not being dislodged when water droplets fall, causing them to accumulate and clump on the surface of the molecular filter membrane. The scrapers remove these particles, ensuring that there are no particle clumps on the surface of the molecular filter membrane that affect the filtration effect.

[0026] Preferably, the medicine tank assembly includes an inlet on the outer wall of the tank. Utilizing the upward movement of exhaust gas, when the electronic nozzle draws alkaline agent from the tank, it neutralizes the acidic gases in the exhaust gas. When the electronic nozzle sprays alkaline agent, the agent is atomized and fills the tank. As the alkaline agent is sprayed, it slowly falls onto several layers of filter cotton. When the exhaust gas passes through these layers of filter cotton, the filter cotton becomes saturated with alkaline agent, ensuring that the acidic gases in the gas are fully decomposed as the exhaust gas passes through the multiple layers of filter cotton. This prevents the spraying system from failing to fully neutralize the exhaust gas due to the dispersion and uncertainty of the gas. When the alkaline agent encounters the acidic gas, in this reaction, the alkaline agent provides hydroxide ions (OH-), and the acidic gas, after dissolving in water to form acid, provides hydrogen ions (H+). + Hydrogen ions and hydroxide ions combine to form water, which neutralizes the acidic gases in the exhaust gas, and a small amount of water flows down to the lower molecular filtration membrane.

[0027] Preferably, the piping assembly includes a second pipe fixedly connected to the inner wall of the medicine tank, with the end of the second pipe away from the medicine tank fixedly connected to the outer wall of the annular pipe. A first pipe is fixedly connected to the outer wall of the medicine tank, with the end of the first pipe away from the medicine tank fixedly connected to the outer wall of the annular pipe. The end of the first pipe away from the annular pipe is also connected through to the outer wall of the water storage space. An outlet is fixedly connected to the outer wall of the tank. Utilizing the fluidity of water, when the scraper removes clumps of particles, the granular water and some unused alkaline agent will fall to the bottom. When the particles fall onto the filter inclined plate, the alkaline agent and the... The water generated is carried by the flow of water and rolls down the filter plate onto the sludge storage platform. As the water and alkaline agent flow from the filter plate to the sludge storage platform, they permeate the filter plate and fall into the water storage space below. They are then re-drawn into the electronic nozzle by a pipe for use. When too much water accumulates in the storage space, it is discharged and collected from the outlet to avoid wasting the alkaline agent and to reduce energy consumption by making full use of the alkaline agent. The filtered particulate sediment accumulates in the sludge storage platform, which is conveniently collected and discharged through the drain outlet, avoiding the troublesome cleaning of the filter components.

[0028] The present invention has the following beneficial effects:

[0029] (1) This invention addresses the problem of difficult-to-clean sediment accumulation during filtration. When exhaust gas enters the equipment, it moves upward through the molecular filter membrane and filter cotton. When excess water flows from the filter cotton into the molecular filter membrane, the water penetrates the membrane and remains on its surface. As exhaust gas moves upward through the membrane, PM2.5 in the exhaust gas is blocked. Due to the layered filtration of the molecular filter membrane, PM2.5 cannot penetrate it, thus achieving the function of filtering dust. When water molecules penetrate the membrane and move downward, they carry the PM2.5 trapped in the membrane outward, forming water droplets containing grit on the membrane surface. This prevents the membrane from being blocked by PM2.5 after prolonged use, thus preventing the filtration system from functioning properly. This invention increases the lifespan of the membrane and extends the frequency of membrane replacement, avoiding frequent membrane replacements that could affect equipment operation.

[0030] (2) The present invention utilizes the force of the above-mentioned exhaust gas movement. When the exhaust gas enters the flue pipe through the feed pipe, the exhaust port in the flue pipe is discharged outward. When the exhaust gas passes through the fan blade, it drives the fan blade to rotate and discharge from the exhaust port, driving the rotating shaft to rotate. When the rotating shaft rotates, it will drive the scraper fixedly connected at the upper end to rotate, scraping the surface of the molecular filter membrane. This prevents some water droplets from falling without carrying small particles, which would cause small particles to adhere to the surface of the molecular filter membrane and clump together. The scraper removes these particles, ensuring that there are no particles clumping on the surface of the molecular filter membrane, thus affecting the filtration effect.

[0031] (3) This invention utilizes the upward movement of exhaust gas. When the electronic nozzle draws alkaline agent from the medicine tank, it neutralizes the acidic gas in the exhaust gas. When the electronic nozzle sprays out alkaline agent, the alkaline agent is atomized and fills the tank. When the alkaline agent is sprayed out, it slowly falls onto several layers of filter cotton. When the exhaust gas passes through several layers of filter cotton, the filter cotton is full of alkaline agent, so that when the exhaust gas passes through multiple layers of filter cotton, the acidic gas in the gas is fully decomposed, avoiding the inability of the spraying system to fully neutralize the exhaust gas due to the dispersion and uncertainty of the gas.

[0032] (4) This invention utilizes the fluidity of water. When the scraper removes the agglomerates of particles, the water and some unused alkaline agent will fall to the bottom. When the particles fall onto the filter inclined plate, they will roll down onto the sludge storage platform due to the water generated during the neutralization of the alkaline agent. As the water and alkaline agent flow from the filter inclined plate to the sludge storage platform, they will seep through the filter inclined plate and fall into the water storage space below. They will be re-inhaled into the electronic nozzle by the pipe for use. When too much water accumulates in the water storage space, it will be discharged and collected from the outlet to avoid wasting the alkaline agent. By making full use of the alkaline agent, energy consumption is reduced. The filtered particulate sediment will accumulate in the sludge storage platform, which is convenient to collect and discharge through the drain outlet, avoiding the problem of cleaning the filter components.

[0060] The flue component includes a flue pipe 221 that is fixedly connected to the inner wall of the base plate 111.

[0061] Medicine barrel mechanism 3 includes:

[0062] Medicine barrel assembly 31 is fixedly connected to the outer wall of the main body 1;

[0063] Pipe assembly 32 is fixedly connected to the inner wall of medicine barrel assembly 31.

[0064] The support assembly 11 includes a discharge pipe 114 fixedly connected to the outer wall of the support frame 113, and a feed pipe 115 fixedly connected to the outer wall of the tank 112.

[0065] Safety component 12 includes a sludge storage platform 125 fixedly connected to the inner wall of tank 112, a filter inclined plate 126 fixedly connected to the inner wall of tank 112, the outer wall of filter inclined plate 126 fixedly connected to the outer wall of sludge storage platform 125, and a water storage space 127 opened at the bottom of filter inclined plate 126.

[0066] The filter assembly 21 includes several filter cottons 212 fixedly connected to the inner wall of the tank 112. A partition plate 213 is fixedly connected to the inner wall of the tank 112, and an annular pipe 214 is fixedly connected to the inner wall of the tank 112. Several electronic nozzles 215 are fixedly connected to the outer wall of the annular pipe 214. When the equipment is turned on, the exhaust gas enters the equipment through the feed pipe 115. When the exhaust gas enters the equipment, it moves upward through the molecular filter membrane 211 and the filter cottons 212. When excess moisture flows from the filter cottons 212 into the molecular filter membrane 211, the moisture penetrates the molecular filter membrane 211 and remains on its surface. When the exhaust gas moves upward through the molecular filter membrane 211, the PM2.5 in the exhaust gas is filtered out. The PM2.5 particles are isolated by the molecular filter membrane 211. Due to the layered filtration of the molecular filter membrane 211, PM2.5 cannot penetrate the molecular filter membrane 211, thus achieving the function of filtering dust. When water molecules penetrate the molecular filter membrane 211 and move downwards, they will carry the PM2.5 intercepted in the molecular filter membrane 211 outwards and remain on the surface of the molecular filter membrane 211, forming water droplets containing sand and gravel. This prevents the molecular filter membrane 211 from becoming clogged with PM2.5 after prolonged use, which would cause the filtration system to malfunction. This extends the service life of the molecular filter membrane 211, prolongs the frequency of replacement, and avoids frequent replacement of the molecular filter membrane 211 affecting the use of the equipment.

[0067] Example 2, please refer to Figures 4-9 This invention relates to a waste gas purification structure for chemical machinery with filtration function. Based on Example 1, the flue assembly 22 includes a rotating shaft 222 rotatably connected to the inner wall of the flue pipe 221. A plurality of fan blades 223 are fixedly connected to the outer wall of the rotating shaft 222, and the fan blades 223 are in close contact with the inner wall of the flue pipe 221. A plurality of smoke outlets 224 are provided on the outer wall of the flue pipe 221. A plurality of scrapers 225 are fixedly connected to the end of the rotating shaft 222 away from the fan blades 223, and the scrapers 225 are in close contact with the outer wall of the molecular filter membrane 211. Utilizing the force of the aforementioned waste gas movement, when the waste gas passes through the feed pipe... 115 enters the flue pipe 221, and the flue pipe 221 is provided with a flue outlet 224 to discharge it outward. When the exhaust gas passes through the fan blade 223, it drives the fan blade 223 to rotate and discharge it from the flue outlet 224, which drives the rotating shaft 222 to rotate. When the rotating shaft 222 rotates, it drives the scraper 225 fixedly connected to it to rotate and scrape the surface of the molecular filter membrane 211. This prevents small particles from not falling off when some water droplets fall, which would cause small particles to adhere to the surface of the molecular filter membrane 211 and accumulate. The scraper 225 removes these particles, ensuring that there are no particles clumps on the surface of the molecular filter membrane 211 that affect the filtration effect.

[0068] The medicine tank assembly 31 includes an inlet 312 on the outer wall of the medicine tank 311. Utilizing the upward movement of exhaust gas, when the electronic nozzle 215 draws alkaline agent from the medicine tank 311, it neutralizes the acidic gas in the exhaust gas. When the electronic nozzle 215 sprays alkaline agent, the agent is atomized and fills the tank 112. As the alkaline agent is sprayed, it slowly falls onto several layers of filter cotton 212. When the exhaust gas passes through these layers of filter cotton 212, the filter cotton 212 becomes saturated with alkaline agent, allowing the exhaust gas to fully decompose the acidic gas as it passes through the multiple layers of filter cotton 212. This prevents the spraying system from failing to fully neutralize the exhaust gas due to the dispersion and uncertainty of the gas. When the alkaline agent encounters the acidic gas, in this reaction, the alkaline agent provides hydroxide ions (OH-), and the acidic gas, after dissolving in water, forms acid, providing hydrogen ions (H+). + Hydrogen ions and hydroxide ions combine to form water, which neutralizes the acidic gases in the exhaust gas, and a small amount of water flows down to the lower molecular filter membrane 211.

[0069] Pipe assembly 32 includes a second pipe 322 fixedly connected to the inner wall of the medicine tank 311. The end of the second pipe 322 away from the medicine tank 311 is fixedly connected to the outer wall of the annular pipe 214. A first pipe 321 is fixedly connected to the outer wall of the medicine tank 311. The end of the first pipe 321 away from the medicine tank 311 is fixedly connected to the outer wall of the annular pipe 214. The end of the first pipe 321 away from the annular pipe 214 is connected through to the outer wall of the water storage space 127. An outlet 323 is fixedly connected to the outer wall of the tank 112. Utilizing the fluidity of water, when the scraper 225 scrapes off granular agglomerates, the granular water and some unused alkaline agent will fall to the bottom. When the granules fall onto the filter inclined plate 126, they will... The alkaline agent, along with the water generated during neutralization, rolls down from the filter plate 126 onto the sludge storage platform 125. As the water and alkaline agent flow from the filter plate 126 to the sludge storage platform 125, they permeate the filter plate 126 and fall into the water storage space 127 below. The water is then drawn back into the electronic nozzle 215 by the pipe 321 for use. When too much water accumulates in the water storage space 127, it is discharged and collected from the outlet 323, preventing the alkaline agent from being wasted and reducing energy consumption by fully utilizing the alkaline agent. The filtered particulate sediment accumulates in the sludge storage platform 125, making it easy to collect and discharge through the drain outlet 124, avoiding the hassle of cleaning the filter components.

[0070] A specific application of this embodiment is as follows: Before use, power is connected to the device, and the feed pipe 115, inlet 312, and outlet 323 are connected to the corresponding pipes. The device is then turned on, allowing exhaust gas to enter the device through the feed pipe 115. When the exhaust gas enters the device, it moves upward through the molecular filter membrane 211 and filter cotton 212. When excess moisture flows from the filter cotton 212 into the molecular filter membrane 211, the moisture penetrates the molecular filter membrane 211 and remains on its surface. As the exhaust gas moves upward through the molecular filter membrane 211, PM2.5 in the exhaust gas is isolated by the molecular filter membrane 211. The layered filtration of the filter membrane 211 prevents PM2.5 from penetrating it, thus achieving the function of filtering dust. When water molecules penetrate the molecular filter membrane 211 and move downwards, they carry the PM2.5 trapped in the molecular filter membrane 211 outwards, remaining on the surface of the molecular filter membrane 211 to form water droplets containing grit. This prevents the molecular filter membrane 211 from becoming clogged with PM2.5 after prolonged use, which would cause the filtration system to malfunction. This extends the service life of the molecular filter membrane 211, prolongs the frequency of replacement, and avoids frequent replacements affecting equipment operation.

[0071] Utilizing the force of the aforementioned exhaust gas movement, when the exhaust gas enters the flue pipe 221 through the feed pipe 115, the exhaust gas is discharged outward through the exhaust port 224 in the flue pipe 221. When the exhaust gas passes through the fan blade 223, it drives the fan blade 223 to rotate and discharge from the exhaust port 224, driving the rotating shaft 222 to rotate. When the rotating shaft 222 rotates, it drives the scraper 225 fixedly connected at the upper end to rotate, scraping the surface of the molecular filter membrane 211. This prevents small particles from not falling off when some water droplets fall, causing small particles to adhere to the surface of the molecular filter membrane 211 and clump together. The scraper 225 removes these particles, ensuring that there are no particles clumping on the surface of the molecular filter membrane 211, which affects the filtration effect.

[0072] Utilizing the upward movement of exhaust gas, when the electronic nozzle 215 draws alkaline agent from the medicine tank 311, it neutralizes the acidic gas in the exhaust gas. When the electronic nozzle 215 sprays the alkaline agent, it is atomized and fills the tank 112. As the alkaline agent is sprayed, it slowly falls onto several layers of filter cotton 212.

[0073] Utilizing the fluidity of water, when the scraper 225 removes particle clumps, the particulate water and some unused alkaline agent fall to the bottom. When the particles fall onto the filter inclined plate 126, they roll down onto the sludge storage platform 125 due to the flow of water generated during the neutralization process of the alkaline agent. As the water and alkaline agent flow from the filter inclined plate 126 to the sludge storage platform 125, they seep from the filter inclined plate 126 and fall into the water storage space 127 below, where they are re-drawn into the electronic nozzle 215 by the pipe 321 for use. When too much water accumulates in the water storage space 127, it is discharged and collected from the outlet 323 to avoid wasting the alkaline agent and reduce energy consumption by making full use of the alkaline agent.
