Description

TECHNICAL FIELD

[0001] The utility model mainly relates to the industrial naphthalene production field, concretely relates to a kind of industrial naphthalene desulfurization device. BACKGROUND

[0002] Naphthalene, also known as naphthalene, is a colorless and shiny flaky crystal. It is insoluble in water, easy to sublimate, and can volatilize with water vapor, with a special odor. It is the most important condensed ring aromatic hydrocarbon in industry, and can be used to produce phthalic anhydride, dye intermediate, rubber additive and insecticide. According to the purity, naphthalene can be divided into industrial naphthalene and refined naphthalene. The purity of industrial naphthalene is generally about 96%. After further purification and removal of impurities and desulfurization, high-purity refined naphthalene can be obtained.

[0003] During the operation of the specific embodiment, the inventor found the following defects:

[0004] When purifying industrial naphthalene to refined naphthalene, industrial naphthalene needs to be put into the inside of the dissolving tank, then ten naphthalene is loaded into the inside of the dissolving tank for dissolution, and then hydrogen is injected into the inside of the dissolving tank for desulfurization treatment of industrial naphthalene. However, since industrial naphthalene accounts for about 20-30% of the total, a large amount of ten naphthalene enters the inside of the dissolving tank, which makes ten naphthalene and industrial naphthalene unable to fully fuse, affecting the subsequent injection of hydrogen and slowing down the desulfurization speed of industrial naphthalene.

[0005] It should be noted that the above content belongs to the technical cognition of the inventor. Since the technical content in this field is vast and complex, the above content of the present application does not necessarily constitute the prior art. CONTENT OF THE UTILITY MODEL
