The invention discloses a bleaching tank, and particularly relates to a blenching tank for the production of dicarboxylic acid. The bleaching tank comprises a tank body comprising an oval seal head B, an oval seal head A and a skirt; a stirring device formed by a shift-down stirrer, a shift-up stirrer, a stirring shaft and a ribbed coupling is arranged in the tank body; a man hole, a feed inlet, a sight glass A, a sight glass B, an activated carbon pulp inlet, an exhaust port, a speed reducer and a motor are arranged at the top of the tank body; the speed reducer and the motor are connected with the tank body by a single-fulcrum rack, a flange and a mechanical seal; a heating coil is arranged in the tank body; the heating coil is fixed on the inner wall of the tank body by a coil fixing frame; a discharge port is formed at the bottom of the tank body; a steam inlet A, a steam inlet B, a steam inlet C, a steam inlet D and a steam inlet E are formed on the side wall of the tank body; a steam outlet A, a steam outlet B, a steam outlet C, a steam outlet D and a steam outlet E are formed at the other side of the tank body; and a thermometer pipe is also arranged on the side wall of the tank body. The bleaching tank has a reasonable structure and high working efficiency and is suitable for the production of the dicarboxylic acid.
Description
technical field [0001] The invention relates to a decolorizing tank, in particular to a decolorizing tank used for the production of long-chain dibasic acids. Background technique [0002] Long-chain dibasic acids are important fine chemical intermediates, which can be used to synthesize a series of high-value-added special chemicals such as spices, special nylon, and polyamide hot-melt adhesives. [0003] Long-chain dibasic acids do not exist in nature and can only be produced by chemical synthesis, vegetable oil cracking and biological fermentation. It is impossible for all long-chain dibasic acids to be directly oxidized from n-alkanes in petroleum by chemical methods, because during chemical oxidation, n-alkanes are broken and a single binary acid with the corresponding chain length of n-alkanes cannot be obtained. acid. Although all long-chain dibasic acids can start from a certain low-carbon chain dibasic acid, through a series of chemical reaction steps such as este...
