Abstract
The invention relates to the technical field of compound fertilizer production, and in particular relates to equipment used in the ammonification granulation process of compound fertilizer production. The ammonification granulation cylinder comprises a cylindrical shell, a feed inlet, an ammonia inlet pipe and a dilute sulphuric acid inlet pipe, with the dilute sulphuric acid inlet pipe and the ammonia inlet pipe parallel to the axis of the cylindrical shell. The ammonia inlet pipe is a three-section structure, including a liquid inlet pipe, a vaporization cavity and a distribution pipe. Wherein, the vaporization cavity is an enclosed circular cylinder, the outlet end of the liquid inlet pipe is installed at the central section of the vaporization cavity, and the liquid inlet pipe body is parallel to the axis of the vaporization cavity, the other end of which is connected to the distribution pipe.
Description
Technical field
The present invention 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 has less investment, strong operability, production capacity height, energy consumption is low, production cost is little advantage, is the production technique of current field of compound fertilizer production widespread use.In this method production process raw material is sent into ammoniation granulator after according to corresponding proportion metering, pulverizing, mixing, in the granulation cylinder, add sulfuric acid and ammonia according to certain dosage.The adding of sulfuric acid and ammonia has following effect: make full use of the heat raising temperature of charge that sulfuric acid and ammonia generation chemical reaction discharge on the one hand, both can increase the material balling ratio, can quicken the material particles moisture evaporation again, alleviate drying pressure, thereby save energy consumption; On the other hand can be by adjusting the consumption of sulfuric acid and ammonia, the pH value of regulating material is in suitable scope.
Ammoniation granulator is constructed at present: opening for feed, dilute sulphuric acid import, ammonia import, granulation cylinder, tail gas absorb mouth, gas solid separation chamber and material outlet.Entering material bed ammonia by the ammonia import has two kinds of forms, and a kind of is liquid ammonia, and another kind is the gasiform ammonia.Liquid ammonia enters the granulation kiln, needs to absorb heat in the liquid ammonia vaporescence, reduces temperature of charge, reduces balling ratio; Liquid in addition ammonia excessive concentration is difficult for spraying evenly in material, is difficult to and the dilute sulphuric acid complete reaction, and the sulfuric acid or the ammonia that cause partial material to absorb are too much, can aggravate ammonia volatilization loss simultaneously.The gaseous state ammonia enters tablets press, then need pass through specific installation---and the vaporization of liquefied ammonia vaporizer so not only increased equipment input and operation cost, and the liquefied ammonia vaporizer certainly exists the portion of energy loss.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in the prior art, a kind of ammoniation-granulation tube is provided.
The technical solution adopted for the present invention to solve the technical problems 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, wherein said ammonia-feeding pipe is a three stage structure, be divided into liquid-inlet pipe, vaporization chamber and distribution pipe, vaporization chamber is a containment cylinder, the exit end of liquid-inlet pipe is arranged on the middle part of vaporization chamber, the body of liquid-inlet pipe and the axially parallel of vaporization chamber are connecting distribution pipe at the other end of vaporization chamber.
The sidewall of described vaporization chamber is provided with steam inlet, and the direction that enters vaporization chamber of steam is vertical with the liquefied ammonia liquid-inlet pipe, 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 pipe.
The invention has the beneficial effects as follows: ammonia sparger of the present invention enters material bed obtains following effect for the gaseous state ammonia with steam mixture: one, enter material with liquid state and become to compare; the mixed gas temperature of steam and gaseous state ammonia is higher; the gaseous state ammonia can be finished chemical reaction rapidly with the dilute sulphuric acid short period of time; tablets press exit material contains the ammonia that chemical reaction does not take place hardly, and tail gas absorbs mouthful place's ammonia concentration and reduced about 30%.Owing to there is not the liquid ammonia vaporescence that in material, absorbs heat, can keep suitable high temperature in the granulation kiln, balling ratio can improve 20%～30%.Two, with the liquefied ammonia vaporizer compare, this device technique principle is simple, and input cost is little, and the operation maintenance expense is low, and energy consumption is little, can obviously reduce production costs.
