[0002] Methyl methacrylate, commonly known as MMA, is an organic compound, mainly used in the production of monomers of transparent plastic polymethyl methacrylate (plexiglass, PMMA). It is volatile and toxic, and it will Explosion occurred, and most of the factories now adopt the propylene route, using carbonylation reaction to generate 2-methoxyisobutyrate methyl ester, and then decomposing it into methyl methacrylate and methanol through hydrolysis reaction, and separating methanol and methyl Methyl methacrylate, and the methyl methacrylate is transported to the collection container through the pipeline, but the pipeline is not equipped with a filter device, resulting in impurities in the obtained methyl methacrylate, which affects the purity of the methyl methacrylate

The invention discloses a transport pipeline for methyl methacrylate. The transport pipeline comprises an inner pipe, wherein a filter device is arranged in the inner pipe; an activated carbon adsorption layer, a fiber cotton filtering layer and a filter are sequentially arranged in the filter device from left to right; the activated carbon adsorption layer comprises an activated carbon placer, activated carbon powder is placed in an inner cavity of the activated carbon placer, and thin films are bonded on two sides of the activated carbon placer; the fiber cotton filtering layer comprises a fiber cotton placer. Impurities in methyl methacrylate are filtered by means of arrangement of the filter device; non-soluble solid impurities can be filtered out through cooperation of a filter body, a filter screen and filter holes; the filtering effect is enhanced by fiber cotton; unseparated methanol can be adsorbed by the activated carbon powder and the thin films, so that obtained methyl methacrylate has higher concentration and contains no impurities.
Description
technical field [0001] The invention relates to the technical field of methyl methacrylate transportation, in particular to a methyl methacrylate transportation pipeline. Background technique [0002] Methyl methacrylate, commonly known as MMA, is an organic compound, mainly used in the production of monomers of transparent plastic polymethyl methacrylate (plexiglass, PMMA). It is volatile and toxic, and it will Explosion occurred, and most of the factories now adopt the propylene route, using carbonylation reaction to generate 2-methoxyisobutyrate methyl ester, and then decomposing it into methyl methacrylate and methanol through hydrolysis reaction, and separating methanol and methyl Methyl methacrylate, and methyl methacrylate is transported in the collecting container through pipeline, but pipeline is not provided with filtering device, causes the methyl methacrylate that obtains to contain impurity in this way, affects the purity of methyl methacrylate.
