Description
Technical field
The present invention relates to the tower reaction unit of a kind of spray-absorption, is the tower carburizing reagent device of spray-absorption of soda balance in a kind of indigo production specifically.
Background technology
At present indigo industrial synthetic process is: anilinoacetic acid potassium/sodium salt and Sodamide in the mixed base of KOH and NaOH is done the system of solvent, alkali fusion occur and react, generation indoxyl potassium/sodium, ammonia and NaOH.After alkali fusion thing dilute with water, blowing air oxidation obtains indigoly after press filtration, and the mother liquor after press filtration is for containing the KOH of alkali 12% and the mixed ammonium/alkali solutions of NaOH.
When alkali fusion reacts, the mixed base K:Na=1:1 of KOH and NaOH, due to when reacting, the sodium in Sodamide is converted into NaOH, and making the potassium sodium ratio in mother liquor is 0.6:1, and NaOH is excessive, after dehydration is reclaimed, does not reach the requirement of making alkali fusion solvent.Existing method is: in mixed alkali, add potassium hydroxide and regulate potassium sodium ratio, it is more than needed that this has just caused mixed base to have, and an alkali part more than needed is carbonized when subsequent oxidation workshop section, becomes sodium carbonate alkaline residue, as solid waste; An alkali part more than needed runs off with indigo wash water, and the diluted alkaline in wash water neutralizes through sulfuric acid, becomes salt, finally becomes waste water, contaminated environment not only, and cause the loss of potassium, wasted potassium resource.
Summary of the invention
In order to solve the deficiency in existing, the invention provides a kind of simple in structurely, easy to use, can effectively regulate mixed alkali potassium sodium ratio, meet the tower carburizing reagent device of spray-absorption of soda balance in indigo production.
The technical solution used in the present invention is: the tower carburizing reagent device of the spray-absorption of soda balance in a kind of indigo production, comprise tower cylindrical shell, upper cover, spray head, cone end socket and discharge nozzle of the slotting end, spray head is arranged in upper cover, upper cover is provided with the air inlet higher than spray head, upper cover is packaged in tower cylinder top, cone end socket is inverted cone shape and is packaged in tower cylindrical shell bottom, insert the corresponding cone of end discharge nozzle lower nozzle end socket back taper bottom, insert end discharge nozzle upper orifice by the tower cylinder lateral wall passing in tower cylindrical shell higher than cone end socket back taper top, its technical characterstic is also to comprise circulation suction line, circulation pipe, circulating pump and feed tube, circulation suction line is connected to exceed on the tower cylindrical shell of inserting end discharge nozzle upper orifice and is communicated with in tower cylindrical shell, circulation suction line is all connected circulating pump with feed tube, circulating pump is communicated with spray head through circulation pipe.
Further, in described tower cylindrical shell, be provided with the inner cone higher than circulation suction line, inner cone is inverted cone shape and bottom end opening.
Further, in described tower cylindrical shell, be provided with agitator.
Further, described agitator is propeller agitator, and propeller agitator is vertically installed on tower cylinder lateral wall.
Further, in described tower cylindrical shell or upper cover, be provided with the cleaning coil pipe that is communicated with outside running water, clean coil pipe and arrange along tower cylindrical shell or upper cover cross section, clean coil pipe outside and be provided with clean-out opening.
Further, described spray head is a plurality of nozzle same level distribution equalizing structures.
Further, described spray head sprays 120 ° symmetrical centered by angle downwards.
Further, described tower cylinder lateral wall is provided with manhole.
Again further, described cone end socket bottom is provided with discharging hole, and the cone end socket bottom conical surface is provided with inspection socket.
When this device is used, by playing circulation containing the mixed alkali liquor of KOH and NaOH46%-48% by feed tube, circulating pump, at CO with pressure
2in airtight tower cylindrical shell, through spray head atomizing spray, absorb CO
2, there is chemical reaction, produce carbonate, due to Na
2cO
3solubility much smaller than K
2cO
3solubility, add in mixed alkali containing a large amount of sodium ions Na in mixed alkali

3supersaturation, makes crystallization separate out by inserting end discharge nozzle, and potassium sodium is played circulation by circulation suction line by circulating pump again than the mixed alkali improving, and comes back in tower cylindrical shell and further improves and regulate potassium sodium ratio, has finally reached the potassium sodium ratio that regulates mixed alkali.
Adopt technique scheme, the invention has the beneficial effects as follows:
1, a plurality of nozzles of spray head are at same level plane spray, and each nozzle does not interfere with each other mutually, can effectively avoid the drop of the nozzle upper strata ejection of arranging up and down to drop on the nozzle of lower floor and form the obstruction that crystallization causes; The alkali lye of circulation forms the tiny droplet cone of 60 ° through spray head atomization, droplet is subject to the effect of air resistance, diffuse to be only subject to gravity do the movement of falling object as the used time, droplet does not arrive tower wall, non-alkali liquor on tower wall, can effectively avoid forming the sticky wall of carbonate crystallization on tower wall, without stifled tower, tower wall crystal deposition phenomenon.
2, the fine mist being sprayed by spray head is dispersed in continuous CO
2in, absorb CO
2, droplet is not dropped down onto on liquid level by any stopping, and equipment resistance is little, and energy consumption is low, coordinates laterally disposed propeller agitator to carry out liquid agitation, further improves reaction efficiency.
3, clean coil pipe and be communicated with on outside running water pipe, by clean-out opening, clean tower wall, it is convenient to clean.In tower cylindrical shell, establish interior centrum, Na
