Integrated tower for removing VOC from polypropylene particles

An integrated tower for removing volatile organic compounds (VOC) from polypropylene particles, comprising:

• a top of the tower;
• a bottom of the tower;
• and
• a middle section of the tower,
• wherein the top and bottom of the tower are respectively provided with a feed inlet and a discharge port, and the middle section of the tower includes a heating and drying section housing and a cooling section housing which are communicating with each other;
• the heating and drying section housing and the cooling section housing are both provided with distribution pipes,
• both sides of the heating and drying section housing are respectively provided with a first air inlet box and a first air outlet box;
• the first air inlet box is respectively communicating with a first heat exchanger and distribution pipes in the heating and drying section housing, and the first heat exchanger is communicating with a blower;
• the first air outlet box is communicating with the distribution pipes in the heating and drying section housing,
• both sides of the cooling section housing are respectively provided with a second air inlet box and a second air outlet box;
• the second air inlet box is respectively communicating with a second heat exchanger and distribution pipes in the cooling section housing, and the second heat exchanger is communicating with the blower;
• the second air outlet box is communicating with distribution pipes in the cooling section housing,
• during operation, the blower sends air to the first heat exchanger, and the first heat exchanger in the heating and drying section heats the air into hot air;
• the hot air enters the distribution pipe through the first air inlet box, and after heat exchange with the materials, it is collected as waste gas in the first air outlet box;
• when the first air outlet box is connected with a dust remover, the first air outlet box sends waste gas to the dust remover, and after dust removal, the waste gas can also enter the first heat exchanger through the blower for recycling;
• the second heat exchanger in the cooling section cools the air into cold air, and the cold air enters the distribution pipe through the second air inlet box;
• after heat exchange with the materials, it is collected as waste gas in the second air outlet box;
• when the second air outlet box is connected with the dust remover, the second air outlet box sends waste gas to the dust remover, and after dust removal, the waste gas can also enter the second heat exchanger through the blower for recycling;
• at the same time, polypropylene particles enter the integrated tower for removing VOC from polypropylene particles from the feed inlet, and are heated, dried and cooled through the distribution pipes in the heating and drying section housing and the cooling section housing respectively, and then discharged through the discharge port, and
• wherein the heating and drying section housing is communicating with the inside of the cooling section housing through a material aggregator.
