Description
Technical field
The utility model belongs to chemical fertilizer manufacturing equipment technical field, and in particular to a kind of jet stream for granulation tower dedusting is micro-
Be soaked generating apparatus.
Background technology
The chemical fertilizer Tower-type melt granulation technique in China is since last century the seventies Introduced From Abroad this technology, from originally
Single urea or ammonium nitrate spheric granules are produced until the granulation tower mesh of the production N P and K ternary compound fertilizer of domestic independent research
Preceding to have spread all over all over the motherland, the agricultural sustainable development for China has played important function.
Key one ring of the granulation tower as fused mass granulating technique, also because of its nuisance while people's abundant affirmation is obtained
The emission problem of matter and gradually paid close attention to by environmental protection administration.
The high tower compound fertilizer fused mass granulating technique in China mainly has two major class of urea-base compound fertilizer and nitro-compound fertilizer, this is two big
The technique of class only melting carrier and technological temperature in terms of have some differences, in addition to this total technological process of two techniques with
And the harmful substance generated is also essentially identical：I.e. from the ammonia-containing gas of fusion tank generation and the simple substance mineral generated from mixing channel
Phosphorus, potassium and filler dust.
Urea or ammonium nitrate as composite fertilizer's melting carrier raw material inevitably generate volatilization in melting process
The ammonia of property, this phenomenon are aggravated with the raising and the extension of fusant residence time of melting temperature.It is produced from fusion tank
Raw harmful substance is mainly the ammonia of volatile and (NOx) pernicious gas of chemical property.
The powder materials such as phosphorus, potassium as composite fertilizer's raw material can generate dust in the technical process for entering mixing channel and fly
It raises, this phenomenon is as the quantity increase of powder raw material and the fineness of powder raw material increase and aggravate.It is produced from mixing channel
Raw harmful substance is mainly solid dust, while also with the chemical noxious gas such as sub-fraction ammonia.
Whether volatile chemical gas or solid dust, whether a large amount of or a small amount of, it is equal to environment
There is negative effect, former capital is to require to be effectively treated scope in environmental protection administration.
During high-tower granulation, whether fusion tank or a mixed slot two mix slot, in container steam inside temperature and
The state slightly larger than local atmospheric pressure can be presented in its space segment under the action of stirring movement, therefore must be set on the end cap of container
The nozzle of about 200 millimeters of the diameter of weighing apparatus pressure, this nozzle are connected by isometrical pipeline inside one holding container of meter, and outlet is straight
It connects and stretches out granulation tower and most of user is in mono- exhaust blower of Chu Duan Installed of this nozzle, enable gas inside container and some
Micro dust is discharged by this pipeline, and the purpose of this measure is exactly the dazzling pungent strong ammonia in order to improve granulation tower working lining
The ambient condition of taste and everywhere dust from flying, the environment of granulation tower working lining has obtained many really under many measures at present
Improve, but since this nozzle is directly stretched to outside hundred meters high of granulation tower working lining, thus these techniques generate it is harmful
Substance has only been transferred to from working site in air.
At present the alternative of composite fertilizer's high tower detoxication substantially there are three, be respectively：
The first scheme is filter material (cloth bag) dust-cleaning scheme, since current granulation tower is generally using gravity-flow ventilation original
Reason, thus to meet the basic fluid condition such as wind speed, wind pressure needed for bag-type dust this technique must just increase it is a set of high-power
Wind turbine, the permeability of filter material and the reliability of continuous work in addition to this must also be considered, because of the filter material of cloth bag etc
Dedusting is not suitable for this kind of strong hygroscopic matter pole such as urea (or ammonium nitrate) phosphorus ammonium and sylvite, and it is long can not to meet this material
The industrial requirement of Time Continuous particularly can not work and clear up at all under the big weather conditions of air humidity, therefore this
One scheme is currently without actual implementation case.
Second scheme is wet method (spray) dust-cleaning scheme, and wet method (spray) dust collecting process is for this water-soluble one
Class substance effect is therefore the granulation tower newly-built in recent years it will be apparent that be easier and dust removing effects are notable due to implementing
This scheme is used mostly.
The third scheme is that electrostatic precipitation ball adding charcoal is adsorbed to the scheme of this two technologies combinations, that is, uses electrostatic precipitation
Dust is caught to flutter, is adsorbed with ball charcoal and catches pernicious gas, but due to program implementation cost and operating cost etc. to flutter
Reason, it is extremely difficult to be received by user, therefore this scheme is at present also without case study on implementation.
But the most wet sprinkling washing process technique of application is still not suitable for high-tower granulation at present, and reason is：
1st, wet method (spray) dust collecting process for this water-soluble substance effect is also compared it will be apparent that implementing
It is easier to, operation principle is that fusion tank and one are mixed to the pernicious gas and powder of two mixed slots with the air-flow that powerful wind turbine generates
The pollutants such as dirt send to the liquid for having enough area and spray region, and the gas containing pollutant is when by spraying region by spray liquid
Body, which is flutterred, to be caught and is dissolved in the liquid, meets the clean gas of environmental requirement spray region is then passed through to leave granulation tower and enter atmosphere
Discharge is completed, what it is due to the dependence of this technique is that the basic fluid condition such as wind speed, wind pressure that wind turbine generates has to be larger than liquid spray
The resistance in region is drenched, therefore will necessarily thus generate a certain number of miniature water mists containing such substance, this micron order therewith
Water mist leave spray region by the kinetic energy of wind turbine, while by hundred meters of height elegant tens of kms with the wind of granulation tower, this
The micron-sized nitrogenous water mist of kind will be far longer than dry minerals dust once taking in its injury to human body by human body！The party
Case seems the pollution for solving granulation tower actually but it is possible that producing another more fearful pollution.
What the 2nd, liquid spray region relied on is that the liquid flow sprayed downwards forms multistage effective water curtain, by pollutant parent
The characteristic of water makes it fall into pond, and the nozzle for generating liquid flow is smaller, i.e., fluid jet is more tiny and the quantity of nozzle is more
That is its more intensive Intercepting effect of liquid flow is better, since the ejecting liquid is to recycle, the powder in liquid in order to prevent
Dirt insoluble matter plug nozzle must just increase the bore of nozzle, and air-flow walks Effect of Short Circuit after the bore of nozzle increases in order to prevent
Intercepting effect is it is necessary to accordingly increase spray area and increase the related parameter that has of water circulating pump and wind turbine, however wind turbine and water pump
Power, i.e. the operating cost of whole device is only what enterprise was concerned about the most, while also having with micron-sized water of being concerned about of enterprise
Mist it is elegant go out granulation tower a large amount of shower waters consumption.
3rd, the technique is not suitable in northern China winter, and freezing point weather can enable device that can not work.
4th, in spite of intensive water curtain but still have a polluted gas and particle flow away short circuit the phenomenon that.
