Industrial naphthalene hydrofining production method and equipment

Abstract

The invention relates to the technical field of industrial naphthalene, and discloses an industrial naphthalene hydrofining production method and equipment. The industrial naphthalene hydrofining production equipment comprises a heating furnace, the upper surface of the heating furnace is fixedly connected with a mixing device through a connecting pipe, and one side of the mixing device is fixedly connected with a hydrogenation reactor through a connecting pipe. According to the industrial naphthalene hydrofining production method and equipment, through arrangement of structures such as a mixing device, a shell, a motor, a transmission rod, a first gear and a second gear, the motor is started to drive the first gear to rotate, the first gear drives a supporting rod to rotate through the second gear, and the supporting rod drives stirring blades and ribbons to rotate, so that new hydrogen and industrial naphthalene in the shell can be effectively mixed and stirred, the retention time of the new hydrogen and the industrial naphthalene in the shell is prolonged through the cooperative use of a flow guide plate, the mixing uniformity of the new hydrogen and the industrial naphthalene is further improved, the reaction efficiency of the hydrogenation reactor is further improved, and the use of workers is facilitated.

Description

technical field [0001] The invention relates to the technical field of industrial naphthalene, in particular to a hydrogenation and refining production method and equipment for industrial naphthalene. Background technique [0002] The main use of naphthalene is to catalyze the oxidation of phthalic anhydride, and it is also used in large quantities to reduce water in cement. In addition, naphthalene oxidation can produce naphthoquinone; naphthalene sulfonation produces naphthol, azo dyes, and dispersants; naphthalene hydrogenation produces tetrahydronaphthalene and decahydronaphthalene It is a solvent with excellent performance; through alkylation, it can produce alkylnaphthalene, 2,6-dialkylnaphthalene, etc., among which 2,6-diisopropylnaphthalene is an important polymer monomer for the production of 2,6-naphthalene dicarboxylic acid Dinonyl naphthalene can be used as a lubricating oil additive after sulfonation. The naphthalene method phthalic anhydride device uses ordinar...
