Description
Technical field
The utility model relates to composite fertilizer's production technical field, especially a kind of equipment that is used for the ammoniation-granulation technological process of composite fertilizer's production.
Background technology
Ammoniation-granulation explained hereafter composite fertilizer is the main flow production technique that current composite fertilizer manufacturing enterprise extensively adopts.This technology is to send in the cylinder tablets press after pulverizing by the plurality of raw materials of metering, adds sulfuric acid and ammonia in the granulation process, keeps material that certain temperature and water ratio are arranged simultaneously, utilizes the granulating method granulating.Advantages such as ammoniation-granulation technology has the production capacity height, energy consumption is low, investment is little, operation cost is low, strong operability.The adding of sulfuric acid and ammonia mainly contains following effect: one, sulfuric acid and ammonia generation chemical reaction, the one side water generation reaction, can reduce the interpolation of water in the granulation process, the heat of chemical reaction release can improve temperature of charge on the other hand, increase balling ratio, be accelerated into the ball particle moisture evaporation simultaneously, alleviate drying pressure; Two, the add-on of control sulfuric acid and the ammonia pH value that can regulate compound fertilizer granules is in the suitable scope; Three, sulfuric acid and raw material DMP effect improve water-soluble phosphorus content; Four, add sulfuric acid in the ammoniation-granulation process, make compound fertilizer granules contain this kind of plant essential nutrient element of sulphur.
Be necessary for dilute sulphuric acid owing to enter the sulfuric acid of ammoniation granulator.Current is that the vitriol oil is passed through specific equipment---sulfuric acid dilution device dilutes, so not only increased the equipment input, increase equipment working cost, also increased energy expenditure, cause the increase of production cost, and a large amount of heats that discharge in the diluting concentrated sulfuric acid process can't utilize, and cause energy dissipation.
Enter material bed ammonia by 3 liquid and two kinds of forms of gasiform are arranged.Liquid ammonia enters the granulation kiln, and the liquid ammonia absorption heat that need gasify reduces local temperature of charge, influences the material balling-up; Liquid ammonia concentration height is difficult in and sprays in the material evenly, can not with the abundant complete reaction of dilute sulphuric acid, cause partial material the phenomenon of sulfuric acid or ammonia to occur too much absorbing, not only can influence the potential of hydrogen of composite fertilizer, also can increase ammonia loss by volatilization.Liquid ammonia enters tablets press, must so must drop into and running cost by increase equipment through the vaporization of liquefied ammonia vaporizer, increases production cost.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of ammoniation-granulation tube is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of ammoniation-granulation tube with ammonia sparger, have cylindrical shell, opening for feed, ammonia-feeding pipe and acid inlet tube, acid inlet tube and ammonia-feeding pipe and cylindrical shell axially parallel, the structure of wherein said acid inlet tube is a syllogic, the pipe connection that is had nothing in common with each other by three sections internal diameters together, be followed successively by water inlet pipe, dilution tube and sour distribution pipe, the tube wall of dilution tube is provided with acid inlet, and acid distribution tube wall is provided with a plurality of shower nozzles; Wherein said ammonia-feeding pipe is a three stage structure, be divided into liquid-inlet pipe, vaporization chamber and distribution piping, vaporization chamber is a containment cylinder, and the exit end of liquid-inlet pipe is arranged on the middle part of vaporization chamber, the body of liquid-inlet pipe and vaporization chamber axially parallel are connecting distribution piping at the other end of vaporization chamber.
The sidewall of described vaporization chamber is provided with steam inlet, and it is vertical with the liquefied ammonia liquid-inlet pipe that steam enters the direction of vaporization chamber, the liquefied ammonia of can effectively vaporizing.
For more uniform distribution ammonia, described distribution tube wall is provided with thrust-augmenting nozzle, and thrust-augmenting nozzle is vertically mounted on the distribution piping.
The beneficial effects of the utility model are: one, the enforcement by this device is owing to following reason can improve temperature of charge.At first, the heat release that is produced during the dilution of the vitriol oil and washing tail gas water can improve an interior temperature of charge in granulating cylinder, and the high temperature dilute sulphuric acid directly is sprayed on the material surface, can improve temperature of charge; Secondly, sulfuric acid and ammonia generation chemical reaction, release of heat.The raising of temperature of charge not only can increase balling ratio, makes balling ratio increase by 25%～35%, can also be accelerated into the ball particle moisture evaporation, makes dry kiln ingress moisture content drop to 2.0%～3.5%; Two, MAP can reduce citric acid soluble phosphorus content about 5% under the vitriolic effect; Three, reduce ammonia loss by volatilization, approximately reduce 10% as calculated.The direct benefit that more than brings is: the production capacity of ammoniation granulator improves 6%, and bunker coal consumption reduces by 10%, and production cost reduces by 25 yuan/ton.
