Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a waste gas treatment system for a plastic extruder. Background Technology

[0002] A plastic extruder exhaust gas treatment system is a device used to treat the exhaust gas and harmful gases generated during the plastic extrusion process. It aims to reduce the impact on the environment and human health. The collected exhaust gas passes through filters and purification equipment, such as activated carbon filters, dust collectors, and chemical absorbents, to remove solid particles, organic compounds, volatile organic compounds, and other harmful substances.

[0003] A search revealed Chinese Patent Publication No. CN215791644U, which discloses a plastic extruder with a waste gas collection mechanism. The extrusion pipe, L-shaped, is mounted on the top of the base plate. A valve is installed near the bottom of the extrusion pipe's inner cavity. Support plates are fixedly connected to the extrusion pipe and the base plate near their left and right sides. A first rotating rod is movably connected to the left inner wall of the extrusion pipe via a bearing, and a first spiral blade is mounted on the first rotating rod. A first motor is mounted on the left side wall of the extrusion pipe. The left end of the first rotating rod passes through the inner ring of the bearing and is fixedly connected to the output shaft of the first motor. A first heating pipe is installed near the left side of the top of the extrusion pipe, and a thicker pipe is installed inside the first heating pipe. The bottom end of the thicker pipe passes through both the first heating pipe and the top of the extrusion pipe. This invention, through a series of structural features, enables the device to collect and process waste gas efficiently. However, the aforementioned structure does not consider the need for effective multi-stage treatment of waste gas, leading to potential leaks that could pose a hazard to air quality and operators, and reducing the equipment's practicality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a plastic extruder exhaust gas treatment system, which aims to improve the problem that the existing technology has not considered, and can effectively perform multiple treatments on exhaust gas, which could easily cause certain dangers to the air and operators if the exhaust gas leaks.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a plastic extruder exhaust gas treatment system, including a processing table. A support plate is fixedly connected to the top left side of the processing table near its edge. A wet scrubber is fixedly connected to the top left side of the support plate. An L-shaped pipe (second L-shaped tube) is connected to the left side of each wet scrubber. An L-shaped pipe (first L-shaped tube) is connected to the right side of each L-shaped pipe (second L-shaped tube). A filter cotton tank is connected to the bottom end of each L-shaped pipe (first L-shaped tube). A long pipe (second L-shaped tube) is connected to the right side of the filter cotton tank. An electrostatic oil removal tank is connected to the right end of each long pipe (second L-shaped tube). A Z-shaped tube is connected to the front side of the centrifugal oil removal tank, and a bracket is fixedly connected to the bottom of the centrifugal oil removal tank. The bottom of the bracket is fixedly connected to the right side of the processing table. An L-shaped tube is connected to the rear side of the centrifugal oil removal tank, and an electrostatic precipitator is connected to the other end of the L-shaped tube.

The right side of L-shaped tube two is further connected to L-shaped tube one. The filter cotton tank plays a preliminary filtration role here, capturing larger particles and performing fine filtration. At the same time, the electrostatic oil removal tank uses the principle of electrostatics to effectively remove tiny oil droplets in the media, improving the purification efficiency.

[0007] As a further description of the above technical solution:

The output end of the exhaust fan is connected to an exhaust pipe.

[0009] The above technical solution involves an activated carbon adsorption device that primarily absorbs and removes harmful gases and odors from the air, ensuring the cleanliness of the air inside the rectangular box. The silicone box is mainly used to regulate the internal humidity, maintain a dry environment, and adsorb harmful gases.

[0010] As a further description of the above technical solution:

[0015] The above technical solution allows for the storage of items that require storage, making them easier for operators to use later.

[0016] As a further description of the above technical solution:

[0017] A battery is fixedly connected to the front right side of the top of the processing table.

[0018] The above technical solution enables the battery to effectively provide power to all devices on the equipment that require electricity.

[0045] Working principle: When exhaust gas needs to be treated, the gas first enters the wet scrubber 14 through L-shaped pipe 2 16 for wet scrubbing. Then, it flows through L-shaped pipe 1 13 to the filter cotton tank 12 for filtration. Next, it is transported through long pipe 2 11 to the inside of the electrostatic precipitator 10 for treatment. Then, it is transported through Z-shaped pipe 9 to the inside of the centrifugal oil removal tank 8 for centrifugal oil removal. The exhaust gas is then further treated through L-shaped pipe 3 22 in conjunction with the electrostatic precipitator 21. Finally, it is treated through L-shaped tube 23 in conjunction with the oil mist purifier 18, and then through the long pipe... The process is completed by placing the treated gas inside the storage box 20. This achieves multiple treatments of the waste gas, effectively reducing its harmfulness and avoiding harm to operators. Subsequently, the gas is transported back to the inside of the long box 201 via the elongated tube 204 connected to the storage box 20. There, the activated carbon adsorption device 205, activated carbon box 208, and silica gel box 209 adsorb the harmful substances in the waste gas. Through the above pretreatment of the waste gas, the blockage of activated carbon is effectively avoided, and the service life of activated carbon is improved.
