Abstract
The utility model relates to equipment used in adipic acid production, in particular to a fixed bed type adipic acid refiner, which solves the problems in case of directly adding activated carbon into a solution for decoloration, such as much equipment, complex operation and high consumption of activated carbon. The fixed bed type adipic acid refiner comprises a cylindrical body, a heat tracing jacket arranged outside the cylindrical body, a liquid inlet formed at the lower part of the cylindrical body, a liquid outlet formed at the upper part of the cylindrical body, and granular activated carbon arranged inside the cylindrical body. The fixed bed type adipic acid refiner has the advantages of simple structure, reasonable design, and good use effect.
Description
Technical field
The utility model relates to a kind of equipment that uses in the adipic acid process of producing, and is specially a kind of adipic acid refining plant of fixed-bed type.
Background technology
In the adipic acid production process,, except containing adipic acid, also have water and other a spot of accessory substance in the reactant solution through after the catalytic reaction.The existence of these accessory substances can influence the quality index such as colourity of adipic acid.The accessory substance that how to remove effectively in the adipic acid is the major issue that faces in the enterprise production process: conventional way is that powder shaped activated carbon and adipic acid crystals water are mixed, and heating for dissolving is then through stirring mixing and absorption, filtration at last.The equipment that this method is used is many, product and active carbon separation difficulty, and complex operation, active carbon can not be reused and cause consumption big, have increased production cost, and refining effect is not good.
Summary of the invention
Problems such as the utility model directly dropping into active carbon in order to overcome that the equipment that the operation of decolouring in the solution brings is many, complex operation, active carbon consumption are big, and a kind of adipic acid treater of fixed-bed type is provided.
The utility model is realized by following technical scheme, a kind of adipic acid treater of fixed-bed type, and structure comprises cylindrical shell, and cylindrical shell is provided with companion's thermal jacket outward, and the cylindrical shell bottom is an inlet, and top is liquid outlet, and granular active carbon is housed in the cylindrical shell.
The granular active carbon specification is the 15-20 order.
During use, with adipic acid crystals and water heating for dissolving, liquid enters from the bottom of cylindrical shell then, liquid rises along active carbon bed in cylindrical shell, accessory substance is adsorbed layer by layer by active carbon in the liquid uphill process, accompanying thermal jacket constantly to prevent to cylindrical shell heating that solution temperature from descending simultaneously causes adipic acid to separate out and causes bed to stop up, liquid is adsorbed through wherein the secondary produce overwhelming majority behind the activated carbon filtration, the requirement that can touch the mark fully such as product purity and colourity, active carbon cleans by heat, can also reuse after the regeneration, reduce production cost, reduced the discharging of solid waste, reached the purpose of environmental protection.The utility model is simple in structure, and is reasonable in design, and result of use is good.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Among the figure: 1-cylindrical shell, 2-heating jacket, 3-granular active carbon, 4-thermometer
The specific embodiment
As schematically shown in Figure 1, a kind of adipic acid treater of fixed-bed type, structure comprises cylindrical shell 1, is provided with heating jacket 2 outside the cylindrical shell 1, and cylindrical shell 1 bottom is an inlet, and top is liquid outlet, and granular active carbon 3 is housed in the cylindrical shell 1.Granular active carbon 3 specifications are the 15-20 order.
Claims (2)
1. the adipic acid treater of a fixed-bed type, it is characterized in that: structure comprises cylindrical shell (1), and cylindrical shell (1) is outer to be provided with heating jacket (2), and cylindrical shell (1) bottom is an inlet, and top is liquid outlet, and granular active carbon (3) is housed in the cylindrical shell (1).
