Environment-friendly waterborne NBR coating material waste-heat utilization and material recycling preparation device

Abstract

The invention discloses an environment-friendly waterborne NBR coating material waste-heat utilization and material recycling preparation device in the technical field of waterborne NBR. The device comprises a drying kettle, a degasifying kettle and a polymerizing kettle; a servo motor is mounted on the right side of the connecting position of the outer wall of the top of the degasifying kettle and a steel tube; an auxiliary gear is mounted at a power end of the top of the servo motor; a driven gear is fixedly arranged on the outer wall of the steel tube in a sleeving manner; the annular outerwall of the polymerizing kettle is wound with a coiled pipe; two groups of U-shaped pipes are perpendicular to each other; the inner cavity of the polymerizing kettle needs to be subjected to a heating reaction; flowing air in the cavities of the U-shaped pipes and the coiled pipe can adsorb heat, and the heat is transferred into the inner cavity of an air heating box; the air in the inner cavityof the air heating box is fed into the U-shaped pipes to heat the inner cavity of the polymerizing kettle through a first air pump and an air pipe; and when a spiral heat exchange pipe is heated, andmeanwhile, the temperature rising speed of inner cavity of the polymerizing kettle can be accelerated, so that the efficiency of a polymerization reaction is 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 production cost and causes serious environmental pollution. Therefore, we propose an environmentally friendly water-based NBR coatin...
