Description

Technical Field

[0001] This invention relates to the field of waste gas purification technology, and in particular to an organic waste gas purification and treatment device for the production of plastic woven bags. Background Technology

[0002] Plastic woven bags are widely used in food, chemical, building materials, and express packaging. The domestic plastic weaving industry is large-scale, with numerous small and medium-sized enterprises using virgin polypropylene and polyethylene materials, as well as recycled waste plastics, as raw materials. The complete production process includes raw material granulation, high-temperature melt extrusion, fiber drawing, circular weaving, color printing and lamination, heat sealing and cutting. During the high-temperature melting, hot stretching, printing and drying stages (180-280℃), the plastic polymers undergo mild thermal decomposition, resulting in the volatilization of large amounts of plasticizers, stabilizers, lubricants, and ink solvents, continuously generating large volumes of organic waste gas. If recycled waste woven bags are used, impurities and adulterated plastics further exacerbate the complexity of pollutants. The core pollutants in the waste gas include: non-methane hydrocarbons, benzene compounds, aldehydes and ketones, tar mist, fine plastic dust, and odorous substances. Some recycled material waste gas contains trace amounts of chlorinated hydrocarbons and sulfides. The waste gas exhibits four main characteristics: large volume, medium to low concentration, high temperature and humidity, presence of viscous tar aerosols, and large fluctuations in concentration under operating conditions, making it a key source of air pollution controlled by the synthetic resin industry.

[0003] Chinese patent CN106978219B discloses a pretreatment device for condensing and capturing tar-laden waste gas, comprising an inlet chamber, a treatment chamber, and an outlet chamber. The inlet chamber is located at the bottom of the treatment chamber, and the outlet chamber is located at the top of the treatment chamber. The treatment chamber consists of a sealed outer shell and airflow pipes. Multiple vertically installed airflow pipes are evenly distributed inside the sealed outer shell. The top of the airflow pipes connects to the outlet chamber, and the bottom of the airflow pipes connects to the inlet chamber. A twisted brush is fixedly installed inside the airflow pipes. Multiple evenly distributed spray pipes are provided at the bottom of the outlet chamber. The device of this invention comprehensively treats high-temperature waste gas containing tar. The waste gas is cooled by the dual action of airflow and spray liquid, resulting in high cooling efficiency. Simultaneously, the tar condensed in the waste gas is captured by the twisted brush. The tar collected on the twisted brush is cleaned by the spray liquid, completing the cleaning work of the device. The device concentrates all multiple operations in the treatment chamber, resulting in good practical effects. This device uses an airflow pipe to condense the exhaust gas. In a conventional smooth airflow pipe, the exhaust gas flows in a laminar straight line. The central airflow does not contact the low-temperature pipe wall throughout the entire process. Only a thin layer of gas on the pipe wall participates in heat exchange, resulting in high thermal resistance and extremely low heat exchange utilization. Furthermore, simply extending the pipe length cannot effectively improve the condensation effect. Summary of the Invention

The outer side of the positioning frame is rotatably connected to the inner side of the base plate through a rolling bearing. When the high-temperature and high-pressure exhaust gas enters the heat exchange tube, under the guiding action of the spiral baffle, the central airflow that originally moves in a straight line is forced to change into a swirling flow that moves along a spiral trajectory. This forces the high-temperature gas in the center of the pipe to be thrown towards the pipe wall and directly contact the low-temperature wall surface for heat exchange, effectively improving the condensation effect.

[0005] Preferably, the turbulence-disrupting device further includes: The rubber scraper is made of rubber. One side of the rubber scraper is fixedly connected to the outer side of the spiral baffle via a bracket. Multiple sets of rubber scrapers are provided.

When the spiral baffle rotates, it drives the rubber scraper to move along the inner wall of the heat exchange tube.

The air blowing pipe 88 has a circular tubular structure and an air blowing hole 89 opened on the air blowing pipe 88. The bottom of the air blowing pipe 88 is connected to an inflation pipe 810, the bottom of the inflation pipe 810 is connected to a horizontal pipe 811, and one end of the horizontal pipe 811 is connected to an air inlet pipe 812.

[0023] One end of the water inlet pipe 2 is connected to the side of the cooling cylinder 1. The interior of the cooling cylinder 1 is filled with coolant. The bottom of the gas supply pipe 7 is connected to the top of the heat exchange pipe 6. The gas supply pipe 7 passes through the top of the cooling cylinder 1 and is fixedly connected to the cooling cylinder 1. There are multiple sets of heat exchange pipes 6, which are evenly distributed inside the cooling cylinder 1.

[0024] The top of the exhaust pipe 10 is connected to the bottom of the heat exchange tube 6, one end of the outlet pipe 11 is connected to the outside of the exhaust pipe 10, the end of the outlet pipe 11 away from the exhaust pipe 10 passes through the cooling cylinder 1 and is fixedly connected to the outer wall of the cooling cylinder 1, and the liquid outlet pipe 12 passes through the bottom of the cooling cylinder 1 and is fixedly connected to the cooling cylinder 1.

[0027] During use, the exhaust gas generated during production is pressurized by an external compressor and then enters the pretreatment device 9. Simultaneously, coolant is continuously added to the cooling cylinder 1 through the water inlet pipe 2. After treatment by the pretreatment device 9, the exhaust gas is discharged into the heat exchange tube 6 through the gas delivery pipe 7. The airflow entering the heat exchange tube 6 impacts the spiral fan 83 and drives it to rotate. The spiral fan 83 drives the spiral baffle 81 to rotate via the annular plate 82. The spiral baffle 81 drives the base plate 84 to rotate. When the high-temperature, high-pressure exhaust gas enters the heat exchange tube 6, under the guiding effect of the spiral baffle 81, the central airflow, which originally moved in a straight line, is forced to transform into a swirling flow moving along a spiral trajectory. This... The high-temperature gas in the center of the pipe is forced to the pipe wall, directly contacting the low-temperature wall surface for heat exchange, effectively improving the condensation effect. Gas is discharged into the inlet pipe 812 through an external air pump. The gas enters the blowing pipe 88 through the horizontal pipe 811 and the air filling pipe 810 in sequence, and finally exits through the blowing hole 89. The discharged gas can further blow the waste gas in the central gap of the spiral baffle 81 towards the inner wall of the heat exchange tube 6. When the spiral baffle 81 rotates, it drives the rubber scraper 86 to move along the inner wall of the heat exchange tube 6. Once wax or frost condenses, it is immediately scraped off by the rubber scraper 86 and mixed into the airflow and carried away, completely eliminating heat exchange failure caused by frost blockage.

This also prevents the edges of the rotating spiral baffle 81 from being worn by impurities, while improving the quality of exhaust gas condensation recovery. Opening the annular electric slide rail 945 moves the moving frame 944 via the internal electric slider. The moving frame 944 rotates the discharge pipe 943, allowing the exhaust pipe 943 to discharge exhaust gas to different positions on the filter screen 97. This avoids exhausting to the same position on the filter screen 97 for a long time, effectively improving the service life and filtration efficiency of the filter screen 97.
