An environment-friendly water-based nbr coating material waste heat utilization and material recovery preparation device

Abstract

The invention discloses an environment-friendly water-based NBR coating material waste heat utilization and material recovery preparation device in the technical field of water-based NBR, comprising a drying kettle, a degassing kettle and a polymerization kettle. A servo motor is installed on the side, an auxiliary gear is installed at the power end of the top of the servo motor, a driven gear is fixedly sleeved on the outer wall of the steel pipe, a serpentine tube is wound around the outer wall of the polymerization kettle ring, and two sets of U-shaped tubes are installed. They are perpendicular to each other, and the inner cavity of the polymerization kettle needs to be heated. The air flowing in the inner cavity of the U-shaped tube and the serpentine tube can absorb the heat and conduct the heat into the inner cavity of the air heating box, and the air in the inner cavity of the air heating box passes through the first The air pump and the air pipe are sent into the inner cavity of the U-shaped tube to heat the inner cavity of the polymerization kettle. While heating the spiral heat exchange tube, the temperature rise of the inner cavity of the polymerization kettle can be accelerated, and the efficiency of the polymerization reaction can be improved.

Description

technical field [0001] The invention relates to the technical field of water-based NBR, in particular to an environment-friendly water-based NBR coating material waste heat utilization and material recovery preparation device. Background technique [0002] Water-based NBR is also known as liquid nitrile (LNBR). Liquid nitrile (LNBR) can be used to manufacture low-temperature coatings, anti-corrosion coatings, electrical insulation coatings, water-soluble and electrophoretic coatings, and has the advantages of toughness and impact resistance. Liquid nitrile (LNBR) ) preparation process as attached Figure 6 As mentioned above, the water washing and degassing processes are all carried out in the degassing kettle, and the heat energy consumption in the preparation process is relatively large. The gas monomer cannot be recycled, which increases the preparation cost and causes serious environmental pollution. Therefore, we propose an environmentally friendly water-based NBR coati...

[0002] Water-based NBR is also known as liquid nitrile (LNBR). Liquid nitrile (LNBR) can be used to manufacture low-temperature coatings, anti-corrosion coatings, electrical insulation coatings, water-soluble and electrophoretic coatings, and has the advantages of toughness and impact resistance. Liquid nitrile (LNBR) ) preparation process as attached Image 6 As mentioned above, the water washing and degassing processes are all carried out in the degassing kettle, the heat energy consumption in the preparation process is relatively large, and the existing equipment also lacks the utilization device for waste heat, resulting in a large amount of heat energy being wasted, and the exhausted gas from the degassing kettle The gas monomer cannot be recycled, which increases the production cost and causes serious environmental pollution. Therefore, we propose an environmentally friendly water-based NBR coating material waste heat utilization and material recovery preparation device
