Description

Technical Field

[0001] This utility model belongs to the field of activated carbon technology, and in particular relates to a hazardous waste activated carbon flue gas purification system. Background Technology

[0002] Powdered activated carbon (PAC) is a black, fine powder adsorbent material made from raw materials such as wood chips, coconut shells, fruit shells, and coal, which is then refined through physical or chemical activation methods.

[0003] During the processing of existing powdered activated carbon, some of the powdered activated carbon usually moves with the flue gas, which means that the activated carbon is directly emitted into the air. Since activated carbon particles are inhalable particulate matter, they may be inhaled by workers when emitted into the air, causing respiratory diseases. To address this, we provide a hazardous waste activated carbon flue gas purification system. Utility Model Content

[0004] The purpose of this invention is to provide a hazardous waste activated carbon flue gas purification system. Through spring compression, when the protrusion separates from the compression block, the spring rebounds and pulls the filter screen upwards, causing it to vibrate and clean the activated carbon from the filter screen's pores. This solves the problem that in existing systems, some powdered activated carbon moves with the flue gas, resulting in the activated carbon being directly released into the air. Furthermore, activated carbon particles are inhalable particulate matter, which may be inhaled by workers and cause respiratory illnesses when released into the air.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a hazardous waste activated carbon flue gas purification system, including a flue gas pipe for discharging flue gas, and further comprising...

[0007] A connecting portion, installed above the flue gas pipe, is used to guide airflow; and:

[0008] A filter section is installed at the bottom of the connecting section, and the filter section is used to filter activated carbon in the flue gas;

[0009] The filter is then installed above the connector, and the connector is then connected to the flue pipe to filter the flue gas inside the flue pipe.

[0010] Furthermore, the connecting portion includes a conveying assembly for connecting the flue gas pipe; and:

[0011] The mounting component is installed at the bottom of the conveying component and is used to connect the filter section to the conveying component;

[0012] The filter section is connected to the bottom of the conveying assembly via an installation component.

[0013] Furthermore, the filtration unit includes a power assembly for providing power; and:

[0014] A filter assembly is installed on the outside of the power assembly and is used to filter activated carbon in flue gas.

[0015] The internal walls of the filter assembly are cleaned by starting the power unit.

[0016] Furthermore, the conveying assembly includes a connecting box, a flue pipe is inserted into the bottom right side of the connecting box, a flow channel is opened inside the connecting box, a fan is fixedly connected to the inner wall of the connecting box, and an air outlet is opened at the bottom left side of the connecting box. The fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. The fan draws powder into the conveying pipe and conveys it to the target position by generating negative or positive pressure airflow.

[0017] In this process, after the flue gas enters the flow channel through the flue gas pipe, the fan draws the incoming flue gas into the left side of the connecting box and discharges it through the air outlet.

[0018] Furthermore, the installation assembly includes a locking groove formed at the bottom of the connecting box, a locking rod inserted into the locking groove, an installation ring fixedly connected to the bottom of the locking rod, a support frame fixedly connected inside the air outlet, and a protective cover fixedly connected to the top of the support frame;

[0019] The mounting ring is secured by pushing the locking lever into the locking groove.

[0020] Furthermore, the power assembly includes a motor fixedly connected to the top of the support frame, a rotating shaft fixedly connected to the top output end of the motor via a coupling, the bottom of the rotating shaft penetrating the support frame, a connecting ring fixedly connected to the outer surface of the rotating shaft, a scraper fixedly connected to the end of the connecting ring away from the rotating shaft, a rotating disk fixedly connected to the bottom of the rotating shaft, and an extrusion block fixedly connected to the bottom of the rotating disk.

[0021] The motor is located inside the protective cover, which protects the motor from the influence of activated carbon. The scraper is coated with silicon carbide ceramic.

[0022] Furthermore, the filter assembly includes a filter screen one threadedly connected to the bottom of the mounting ring, a filter screen two slidably connected to the inner wall of the mounting ring, a spring fixedly connected to the bottom of the filter screen two, the bottom of the spring being fixedly connected to the inner wall of the mounting ring, and a protrusion fixedly connected to the top of the filter screen two.

[0023] When the scraper rotates, it scrapes the inner wall of the second filter screen. Then, the extrusion block squeezes the protrusion, causing the second filter screen to shake. The holes of the first filter screen are smaller than those of the second filter screen, so the activated carbon discharged from the second filter screen will be blocked by the first filter screen.

[0024] This utility model has the following beneficial effects:

[0025] 1. This utility model uses a pressing block. Specifically, when the rotating shaft rotates, it synchronously drives the rotating disk to rotate. The rotating disk then drives the pressing block to rotate in a circle. When the pressing block rotates in a circle, it presses the protrusion, causing the protrusion to move the filter screen two downwards and press the spring. When the protrusion separates from the pressing block, the spring rebounds and pulls the filter screen two upwards, causing the filter screen two to vibrate and clean the activated carbon in the holes of the filter screen two.

[0026] 2. This utility model uses a locking rod. Specifically, the mounting ring is rotated first, which causes the locking rod to rotate, disengaging it from the locking groove inside the connecting box. Then, the mounting ring is pulled down, causing filter screen one and filter screen two to detach from the connecting box. Finally, filter screen one is rotated to remove it from the mounting ring, allowing for cleaning of the interior of filter screen two and filter screen one. The operation is simple and allows for quick replacement of filter screen one and filter screen two.

[0027] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figures 1-5As shown, this utility model is a hazardous waste activated carbon flue gas purification system, including a flue gas pipe 3 for discharging flue gas, and a connecting part 1 installed above the flue gas pipe 3 for guiding airflow; and a filter part 2 installed at the bottom of the connecting part 1 for filtering the activated carbon in the flue gas; wherein, after the filter part 2 is installed above the connecting part 1, the connecting part 1 is then connected to the flue gas pipe 3 to filter the flue gas inside the flue gas pipe 3; the connecting part 1 includes a conveying assembly 11 for connecting the flue gas pipe 3; and an installation assembly 12. The mounting assembly 12 is installed at the bottom of the conveying assembly 11, and the mounting assembly 12 is used to connect the filter section 2 to the conveying assembly 11; wherein, the filter section 2 is connected to the bottom of the conveying assembly 11 through the mounting assembly 12; the filter section 2 includes a power assembly 21, which is used to provide power; and a filter assembly 22, which is installed outside the power assembly 21, and is used to filter activated carbon in the flue gas; wherein, the inner wall of the filter assembly 22 is cleaned by starting the power assembly 21; the conveying assembly 11 includes a connecting box 111, and a flue gas pipe 3 is inserted into the bottom right side of the connecting box 111, and the connecting box 111 has an opening inside. The connection box 111 has a flow channel 112, a fan 113 fixedly connected to the inner wall of the connecting box 111, and an air outlet 114 at the bottom left side of the connecting box 111. After the flue gas enters the flow channel 112 through the flue gas pipe 3, the fan 113 draws the flue gas into the left side of the connecting box 111 and raises the air outlet 114 to discharge it. The mounting assembly 12 includes a locking groove 123 at the bottom of the connecting box 111, a locking rod 122 inserted into the locking groove 123, a mounting ring 121 fixedly connected to the bottom of the locking rod 122, a support frame 124 fixedly connected inside the air outlet 114, and a protective cover 125 fixedly connected to the top of the support frame 124. The mounting ring 121 is fixed by pushing the locking rod 122 into the locking groove 123. First, the mounting ring 121 is rotated, which drives the locking rod 122 to rotate, causing it to disengage from the locking groove 123 inside the connecting box 111. Then, the mounting ring 121 is pulled down, causing the filter screen 1 221 and filter screen 222 to disengage from the connecting box 111. Then, the filter screen 1 221 is rotated to remove it from the mounting ring 121, so that the filter screen 222 and the inside of the filter screen 1 221 can be cleaned. The operation is simple and the replacement of filter screen 1 221 and filter screen 222 can be completed quickly.The power assembly 21 includes a motor 211 fixedly connected to the top of the support frame 124. A rotating shaft 212 is fixedly connected to the top output end of the motor 211 via a coupling. The bottom of the rotating shaft 212 passes through the support frame 124. A connecting ring 213 is fixedly connected to the outer surface of the rotating shaft 212. A scraper 214 is fixedly connected to the end of the connecting ring 213 away from the rotating shaft 212. A rotating disk 215 is fixedly connected to the bottom of the rotating disk 215, and an extrusion block 216 is fixedly connected to the bottom of the rotating disk 215. The motor 211 is housed inside a protective cover 125, which protects the motor 211 from the influence of activated carbon. When the rotating shaft 212 rotates, it synchronously drives the rotating disk 215 to rotate, which in turn drives the extrusion block 216 to rotate circumferentially. During the circumferential rotation of the extrusion block 216, it impacts the protrusion 216. The 24th step applies pressure, causing the protrusion 224 to move the filter screen 222 downwards and press the spring 223. When the protrusion 224 disengages from the pressing block 216, the spring 223 rebounds and pulls the filter screen 222 upwards, causing the filter screen 222 to vibrate and clean the activated carbon in the holes of the filter screen 222. The filter assembly 22 includes a filter screen 221 threadedly connected to the bottom of the mounting ring 121, a filter screen 222 slidably connected to the inner wall of the mounting ring 121, a spring 223 fixedly connected to the bottom of the filter screen 222, the bottom of the spring 223 fixedly connected to the inner wall of the mounting ring 121, and a protrusion 224 fixedly connected to the top of the filter screen 222. When the scraper 214 rotates, it scrapes the inner wall of the filter screen 222, and then the pressing block 216 presses the protrusion 224, causing the filter screen 222 to shake.

[0038] A specific application of this embodiment is as follows: During use, the flue gas inside the flue pipe 3 enters the flow channel 112 inside the connecting box 111, and then the fan 113 is started. The fan 113 guides the airflow, causing it to enter the filter screen 222 through the air outlet 114. The airflow then passes through the filter screen 222 and the filter screen 221. When the airflow passes through the filter screen 222, the activated carbon in the airflow is filtered, causing the airflow to separate from the activated carbon. During long-term use, the inner wall and pores of the filter screen 222 will develop... When the filter screen is covered with activated carbon, motor 211 is activated, which drives shaft 212 to rotate. Shaft 212 then drives connecting ring 213 to rotate, which in turn drives scraper 214 to rotate. Scraper 214 scrapes away the activated carbon from the inner wall of filter screen 222. Simultaneously, the rotation of shaft 212 drives rotating disk 215 to rotate, which in turn drives pressing block 216 to rotate circumferentially. The protrusion 224 is squeezed, causing it to move the filter screen 222 downwards and compress the spring 223. When the protrusion 224 disengages from the compression block 216, the spring 223 rebounds, pulling the filter screen 222 upwards, causing it to vibrate and clean the activated carbon from the holes. During this cleaning process, some activated carbon is discharged from the holes of the filter screen 222 and falls into the filter screen 221. This process is then repeated when the activated carbon inside the filter screens 222 and 221 needs further cleaning. During cleaning, first rotate the mounting ring 121. The rotation of the mounting ring 121 will drive the locking rod 122 to rotate, causing it to disengage from the locking groove 123 inside the connecting box 111. Then, pull the mounting ring 121 downwards to disengage filter screen 1 221 and filter screen 2 222 from the connecting box 111. Then, rotate filter screen 1 221 to remove it from the mounting ring 121, so as to clean the inside of filter screen 2 222 and filter screen 1 221. The operation is simple and can quickly complete the replacement of filter screen 1 221 and filter screen 2 222.
