Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to a high-temperature waste gas treatment device. Background Technology

[0002] High-temperature waste gas treatment devices are used to treat high-temperature waste gases generated during industrial production processes. These waste gases typically contain harmful substances and particulate matter, posing a threat to the environment and human health. The design and application of high-temperature waste gas treatment devices need to consider factors such as the composition, temperature, and flow rate of the waste gas, and combine multiple treatment technologies to achieve the best purification effect.

[0003] In the process of high-temperature waste treatment, the most common method is to use a high-temperature incinerator. The waste gas needs to be preheated in the incinerator before being sent inside for combustion. The waste gas contains not only gases but also some impurities. Moreover, because incinerators are generally quite large, the combustion conditions are not easy to control, such as insufficient temperature, insufficient residence time, and insufficient oxygen supply. As a result, some impurities or organic matter in the waste gas are not completely burned, thus producing highly toxic substances such as dioxins. Dioxins have strong carcinogenic, teratogenic, and endocrine-disrupting properties and need to be treated. Utility Model Content

[0004] This invention proposes a high-temperature waste gas treatment device, which solves the problem in the prior art that after the waste gas undergoes high-temperature combustion treatment, some toxic substances are generated due to the combustion of impurities in the waste gas, requiring further treatment.

[0005] The technical solution of this utility model is as follows:

[0006] A high-temperature waste gas treatment device includes a furnace body, an inlet pipe, and an outlet pipe. The inlet pipe is connected to one end of the furnace body, and the outlet pipe is connected to the end of the furnace body that is longitudinally parallel to the inlet pipe. The device further includes:

[0007] A rotating collection mechanism is provided at the other end of the exhaust pipe to collect the treated exhaust gas inside the furnace body.

[0008] A stirring and filtering mechanism is provided inside the rotating collection mechanism for stirring and filtering the waste gas collected inside the rotating collection mechanism.

[0009] An activated carbon filter plate is detachably connected to the end of the rotating collection mechanism away from the outlet pipe, and is used to filter the waste gas filtered by the stirring filter mechanism.

[0010] The discharge frame is fixedly connected to the end of the activated carbon filter plate away from the rotating collection mechanism, and is used to discharge the filtered waste gas outward.

[0011] Preferably, the rotating collection mechanism includes:

[0012] A gas collection box, which is connected to the end of the gas outlet pipe away from the furnace body;

[0013] Motor 1, which is installed on the top of the gas collection box;

[0014] Gear 1, which is fixedly connected to the output end of motor 1;

[0015] Two rotating shafts are fixedly connected to the inner top wall of the gas collecting box, and the two rotating shafts are arranged on both sides of the gear one;

[0016] Gear 2, the other end of the two shafts is rotatably connected to gear 2, and both gear 2 mesh with gear 1;

[0017] The connecting rod is fixedly connected to the end of gear one and the two gear two that are away from motor one.

[0018] Activated carbon rods are detachably connected to each of the connecting rods.

[0019] Preferably, the stirring and filtering mechanism includes:

[0020] Motor 2, which is installed on top of the gas collection box;

[0021] A stirring rod, which is fixedly connected to the output end of the second motor;

[0025] Furthermore, a filter screen is detachably connected to the outlet end of the discharge frame.

[0026] The working principle and beneficial effects of this utility model are as follows:

[0027] In this invention, when using a high-temperature waste gas treatment device to treat waste gas, toxic substances such as dioxins are easily produced after the waste gas is burned at high temperatures. If it is discharged directly, it will cause environmental pollution. Therefore, after the waste gas is treated by high-temperature combustion, it can flow from the exhaust pipe into the rotating collection mechanism. At the same time, the stirring and filtering mechanism is activated to adsorb and filter the incoming waste gas. After adsorption and filtration, the waste gas passes through the activated carbon filter plate and is then discharged out through the discharge frame. At this time, after multiple layers of activated carbon adsorption and filtration, the toxic substances in the waste gas can be greatly reduced, reducing pollution to the environment and human body.

The stirring and filtering mechanism is located inside the rotating collection mechanism and is used to stir and filter the waste gas collected within the rotating collection mechanism. The activated carbon filter plate 4 is detachably connected to the end of the rotating collection mechanism away from the outlet pipe 3 and is used to filter the waste gas filtered by the stirring and filtering mechanism. The discharge frame 5 is fixedly connected to... The end of the activated carbon filter plate 4 away from the rotating collection mechanism is used to discharge the filtered waste gas outward. The end of the activated carbon filter plate 4 facing the gas collection box 101 is fixedly connected to a fixing column 6. The end of the gas collection box 101 away from the gas outlet pipe 3 is provided with a fixing hole 7 corresponding to the fixing column 6. The purpose is to accurately position and facilitate disassembly for cleaning and replacement. The interior of the discharge frame 5 is set with an arc-shaped surface 8. The purpose is to prevent some impurities filtered out from adhering to the filter screen 9 and causing blockage. The connection between the discharge frame 5 and the activated carbon filter plate 4 is set with a straight surface. The main purpose is to collect the slipped material in the frame. The outlet end of the discharge frame 5 is detachably connected to the filter screen 9, which is also for better filtering of impurities in the waste gas.

[0038] In this embodiment, the rotating collection mechanism includes a gas collecting box 101, a motor 102, a gear 103, a rotating shaft 104, a gear 105, a connecting rod 106, and an activated carbon rod 107. The gas collecting box 101 is connected to the end of the gas outlet pipe 3 away from the furnace body 1. The motor 102 is installed on the top of the gas collecting box 101. The gear 103 is fixedly connected to the output end of the motor 102. Two rotating shafts 104 are fixedly connected to the inner top wall of the gas collecting box 101, and the two rotating shafts 104 are arranged on both sides of the gear 103. The other ends of the two rotating shafts 104 are rotatably connected to the gear 105, and both gears 105 mesh with the gear 103. The ends of the gear 103 and the two gears 105 away from the motor 102 are all fixedly connected to the connecting rod 106. Each connecting rod 106 can be detachably connected to an activated carbon rod 107.

[0039] In this embodiment, the stirring and filtering mechanism includes a second motor 201, a stirring rod 202, and activated carbon stirring blades 203.

At the same time, gear 205, which meshes with gear 103, also rotates. When gear 103 and gear 205 rotate, they drive activated carbon rod 107 to rotate. When the waste gas enters the gas collection box 101... Afterwards, the gas will first pass through the adsorption and filtration of the activated carbon rods 107. After adsorption and filtration by the activated carbon rods 107, the gas will reach the area of ​​the activated carbon stirring blades 203. At this time, the motor 201 drives the activated carbon stirring blades 203 to rotate and filter the exhaust gas in the gas collection box 101. During the rotation, some toxic substances will be carried up and adsorbed on the activated carbon stirring blades 203. Then, the exhaust gas will pass through the activated carbon filter plate 4 and the filtered exhaust gas will be discharged outward through the discharge frame 5. When it is discharged outward, some substances will be blocked on the filter screen plate 9 and will slide into the straight discharge frame 5 through the internal arc surface 8. Only periodic cleaning by workers is required.
