Abstract

The invention discloses a treatment system and method for acrylic acid and ester waste oil of the acrylic acid. The treatment system comprises a depolymerizing kettle, a diluent buffer tank, a diluting kettle, an emptying and trapping machine, a tail gas buffer tank, an atomizer, an incinerator, a denitrating tower, a waste heat boiler, a dust removal chamber and a desulfurization tower. The treatment method is characterized in that organic waste acid is used for diluting the acrylic acid and the ester waste oil of the acrylic acid so as to reduce the viscosity of the acrylic acid and the ester waste oil of the acrylic acid, then the acrylic acid and the ester waste oil of the acrylic acid are thoroughly treated after undergoing atomization, incineration, denitration, waste heat recovery,dust removal and desulfuration and can meet the national emission standards, and meanwhile, steam which is generated through burning heat of the acrylic acid and the ester waste oil of the acrylic acid is returned to a production line for recycling. According to the treatment system and method, the breakthrough design concept of using waste to treat waste is adopted, pretreatment, atomization, incineration, denitration, waste heat recovery, dust removal and desulfuration of the acrylic acid and the ester waste oil of the acrylic acid are integrated, various flue gas emission indexes are far lower than the national environmental protection emission standards, so that remarkable practicability and economic benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of industrial waste treatment, and in particular relates to a treatment system and method for acrylic acid and ester waste oil. Background technique [0002] As an important derivative of propylene, acrylic acid is used to synthesize methyl acrylate, ethyl ester, butyl ester, and isooctyl ester, etc., which are also monomers for synthesizing polymers, and are widely used in rubber, medicine, leather, paper, adhesives, etc. Mixture and coating industry. At present, the amount of waste oil produced in the production process of acrylic acid and acrylic acid esters is increasing, which requires corresponding treatment. The main components of methyl acrylate waste oil are methyl acrylate, acrylic acid, methanol, water, and methyl methoxyacrylate. The recovery process of acrylic acid and ester waste oil in the prior art mainly utilizes the cracking reaction to recover acrylic acid, and its process mainly include...
