Description
Technical field
The utility model relates to a kind of adipic acid production equipment, specifically refers to a kind of adipic acid decolouring system.
Background technology
Charcoal absorption is the method for treating water that the performances such as physical absorption, chemisorbed, oxidation, catalytic oxidation and reduction of utilizing active carbon are removed water pollutant.Specifeca tion speeification is the adsorption capacity and the rate of adsorption.Adsorption capacity is that the Unit Weight active carbon reaches absorption adsorbable solute amount when saturated, and is relevant with raw material, manufacture process and renovation process.Adsorption capacity is big more, and used active carbon is economized more; The rate of adsorption is meant Unit Weight active carbon adsorbable solute amount in the unit interval.Because of being adsorbed with selectivity, performance parameter should be by measuring.Granular activated carbon will have certain mechanical strength and particle diameter specification.Solute in the continuous adsorbed water of active carbon, up to adsorption equilibrium be solute concentration when no longer changing till.
The adipic acid charcoal absorption is exactly coloring matter and the impurity that utilizes this principle to adsorb to be dissolved in the solution of adipic acid.The existing adipic acid system of decolouring normally adopts the mode of freely adsorbing in horizontal active carbon dissolving tank.The time of staying of adipic acid in dissolving tank is short, can not fully adsorb, so can also further improve decolorizing effect.
Summary of the invention
The utility model technical problem to be solved is the present situation to prior art, and a kind of adipic acid decolouring device that can effectively improve the adsorption capacity and the rate of adsorption is provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this adipic acid decolouring system; Comprise the adsorption tanks that are used for adsorbing adipic acid slurry coloring matter and assorted material; Said adsorption tanks are provided with first inlet that is used in adsorption tanks, carrying the adipic acid slurry that is connected with upstream process; It is characterized in that described adsorption tanks are vertical structure; And be provided with agitating device in the adsorption tanks, the top of adsorption tanks also is provided with second inlet that is used in adsorption tanks, carrying active carbon suspension that is connected with the active carbon conveyance conduit, and the outlet of said adsorption tanks connects the material inlet of first filter; The bottom of first filter is provided with the waste outlet that is connected with the active carbon storage facilities; The top of said first filter is provided with the material outlet that is connected with the charging aperture of second filter, and described charging aperture is arranged on the bottom of said second filter, the adipic acid that obtains decolouring at the top exit of second filter.
Described first filter and described second filter are candle structure filter.
Described first filter has a plurality of, and these first filters are connected in parallel.
Described first filter has two.
Compared with prior art; The utility model changes adsorption tanks into vertical structure; Increased the time of staying of adipic acid slurry in adsorption tanks; In adsorption tanks, disposed simultaneously agitating device, utilized to stir to enlarge the contact area between active carbon and the slurry, thereby reach the purpose that improves the adsorption capacity and the rate of adsorption; And the further recovered carbon suspension of the design of second filtering tank in the utility model, and can effectively improve the precision of decolouring back adipic acid; The design of a plurality of first filtering tanks then can increase the disposal ability of system.The utility model can significantly reduce the colourity of smart adipic acid.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, this adipic acid decolouring system comprises:
Adsorption tanks 1 are vertical structure, are provided with agitator 11 in it, and the side wall upper part of adsorption tanks 1 is provided with first inlet 15 that is connected with the discharging opening of adipic acid dissolving tank 4, and the adipic acid slurry in the adipic acid dissolving tank 4 gets in the adsorption tanks 1 from first inlet 15; The top of adsorption tanks 1 is provided with second inlet 12, and this second inlet 12 connects active carbon conveyance conduit 13, and active carbon suspension gets in the adsorption tanks 1 from second inlet 12 through active carbon conveyance conduit 13; The bottom of adsorption tanks 1 is provided with outlet 14, and this outlet connects the material inlet 23 of following first filter 2 through pump 5.
The course of work of above-mentioned adipic acid decolouring system is following:
Solution of adipic acid through dissolving tank 4 dissolvings gets into adsorption tanks 1 from first inlet 15; Active carbon suspension gets in the adsorption tanks 1 from second inlet 12; Under the stirring action of agitator 11; Effectively increase the contact area and the touch opportunity of solution of adipic acid and active carbon, strengthened solution and interparticle turbulence, improved the adsorption rate of active carbon; Thereby make active carbon suspension fully contact about 90 ℃ with lysed solution of adipic acid, active carbon fully adsorbs the foreign pigment in the solution of adipic acid; And the adsorption tanks of vertical structure can increase the time of staying of solution of adipic acid, so that adsorb carry out more abundant.
Mixed material after fully absorption, the decolouring gets into first filter 2 of two candle structures through pump 5; The activated carbon composition in the mixed material is gone out in filtration; The waste active carbon that obtains after the filtration gets into waste active carbon storage pool 6 and stores; The adipic acid that obtains after the filtration gets into second filter 3 of candle structure, further removes by filter the active carbon that remains in the adipic acid, after the filtration; Residual waste active carbon enters waste active carbon storage pool 6 from the outlet of second filter, has obtained removing the pure adipic acid of impurity at the top exit of second filter.
