Abstract

The invention discloses an agglomeration kettle of a rubber polymer. The agglomeration kettle is used for vaporization and removal of a solvent in a rubber polymer solution so that a micelle solution of the rubber polymer is obtained. The agglomeration kettle comprises a rubber polymer solution feeding unit for introducing a mixture of the rubber polymer solution and water into the agglomerating kettle, a steam feeding unit for introducing steam into the agglomerating kettle so that the steam contacts with the mixture, and a water separation unit for separating a part of water from the contacted material. The invention also provides an agglomeration device of a rubber polymer solution and the agglomeration device uses the agglomerating kettle. The invention also provides an agglomeration method of a rubber polymer solution based on the agglomeration device. When the polymer solution is agglomerated by the agglomeration kettle, the agglomerating kettle can realize concentration, prolong the residence time of the micelle solution in the agglomeration kettle, and enhance the solvent removal effects of the polymer solution.

Description

technical field [0001] The invention relates to an agglomeration kettle and an agglomeration device for rubber polymer and an agglomeration method for rubber polymer solution. Background technique [0002] The production process of common rubber-like polymers usually includes units such as polymerization units, agglomeration units, and post-treatment units. In the polymerization unit, one or more monomers are polymerized in a solvent under the action of a catalyst to obtain a polymer solution; The solvent in the process is separated by flash evaporation; the water-containing polymer obtained from the coagulation unit is then dried and other post-treatment processes to obtain the polymer product. The coagulation process of the water analysis method is to disperse the colloidal particles in the form of droplets in the water under mechanical agitation, and then directly inject steam to heat the water by condensing part of the steam to release latent heat, and the heat is trans...
